News https://dmcivil.com.au/news/rss 2021 CCF Industry and Training Awards https://dmcivil.com.au/news/2021-ccf-industry-and-training-awards/ <p>The 2020 CCF Industry and Training Awards was held on Friday 16th April and we were so thrilled to announce that Joshua, Richard and Tessa won their respective categories!</p> <p><strong>Josh - Apprentice of the Year.</strong> Determined to achieve a trade, Josh enrolled himself into and completed a Cert II pre-apprenticeship in Heavy Vehicle Servicing and proactively sought employment after he was made redundant from his previous electrical apprenticeship due to an industry downturn. In November 2018 DM Civil signed him up for a Cert III in Mobile Plant Technology.</p> <p>Josh takes pride in being able to apply new concepts in the workplace. When he completed the air conditioning units of his course, he promptly contacted his TAFE trainer for the Cert II in Automotive Air Conditioning Technology certificate so he could apply for a refrigerant handling licence, allowing him to work on air conditioning equipment fitted to company vehicles.</p> <p>Josh respects the tradespeople he works with. He’s eager to learn from them and support all workshop and field personnel. The skills and knowledge he’s attained as part of his apprenticeship has now allowed Josh to work more independently in the field and on remote sites.</p> <p><strong>Richard - Supervisor of the Year.</strong> Throughout 2020, Richard showed both the desire and the capability to exceed the responsibilities of a Supervisor by managing and delivering projects without the assistance of project management and engineering resources. Richard not only has excellent site management and construction experience to deliver project works, he has administration and organisation skills that has allowed him to assume roles generally completed by Construction and Project Managers.</p> <p>Richard creates a strong team dynamic through his thorough understanding of each project’s scope, including the coordination and planning of resources, HSEQ requirements, procurement and logistics. He maps out project sequencing, identifying key milestones and pathways to achieve them and communicates this succinctly to all involved with appropriate notice. This measured approach to critical elements of work results in strong decision making and confidence from stakeholders.</p> <p>Richard’s maturity, leadership qualities and ability to solve unexpected issues professionally are just a few indicators of his depth. He leads by example and actively adheres to and promotes company values and culture, systems and procedures. He doesn’t claim to know everything, will seek the expertise and knowledge of senior personnel and involves his team in construction solutions or decision making processes. In turn, everyone understands each other’s capabilities and roles on site.</p> <p><strong>Tessa - Engineer of the Year.</strong> Throughout 2020, Tessa excelled as Project Engineer on the Fremantle Cast Iron Water Main replacement. Her duties included material supply and delivery coordination, variations and progress claims, stakeholder management, contributing to commissioning activities, managing traceability and QA. Tessa exceeded these responsibilities by delivering expertise in project design, providing direction for quality assurance system improvements and maintaining professional communication and liaison with all stakeholders.</p> <p>Tessa’s leadership comes naturally because she’s so attentive to project detail and knowledge that people trust her planning, decision making and direction. They’re confident that she’s researched project requirements and will listen to advice and expertise from her crews. She’s always respectful and patient, providing context, facts and solution-focused information for the message she’s delivering. On the back of her superior performance, Tessa was promoted to Project Manager. The Roleystone DN760 Pipe Renewal is her first standalone project and comes with very unique challenges, which she’s doing an outstanding job of project managing.</p> <p>We congratulate Josh, Richard and Tessa for their outstanding contribution and achievements in 2020 and look forward to their continued development and success with DM Civil.</p> Thu, 24 Jun 2021 11:40:54 +0800 https://dmcivil.com.au/news/2021-ccf-industry-and-training-awards/ Pipes for Fremantle https://dmcivil.com.au/news/pipes-for-fremantle/ <p>As part of the Water Corporations, Pipes for Fremantle project, DM Civil was an integral part in the renewal of 2.1 kms of ageing water mains with new pipelines in Fremantle. DM Civil was contracted to replace century-old cast iron water mains in the heart of Fremantle to ensure safe and reliable water supply in the area.</p> <p>DM Civil started works in April 2020 and completed the project in November 2020, under controlled stages, to ensure that the works footprint could be managed efficiently and minimise the community disruption and traffic flow over an extensive area. The staging was targeted on a street-by-street basis covering; High Street Stage 1 – Market St to Henry St, High Street Stage 2 – Henry St to Roundhouse, Essex Street, Essex Lane, Leake and Cantonment Street, Nairn Street, Marine Terrace and Norfolk Street. Streets were identified as a single stage and if the street extended greater than 300m, this was split into two stages. High Street and Marine Terrace being 480m and 564m respectively was broken into two stages for works. The size of the new mains ranged from 100mm diameter up to 250mm diameter and approximately 282m was installed to allow for connections to the existing water mains at connecting streets and intersections.</p> <p>Fremantle is within a recognised heritage zone. The CI works were completed under a strict heritage management plan. This plan incorporated supervision by Archaeological experts, Archae Aus, during excavation activities to assist in recovery, cataloguing and managing items that were discovered during the works.  Generally, objects that were exposed included bottles, glass fragments, pottery and tile fragment and animal bones such as sheep and cattle.</p> <p>The greatest challenge on CI Renewals in urban areas is allowing for the unknowns. Under the asphalt in High Street, DM Civil discovered two layers of concrete that was approximately 450mm thick. There was a 150mm thick concrete slab and then underneath this a 300mm limestone spall layer fill with cement slurry. We now believe this was the original foundation for the tramway that was in place between the early 1900’s and the 1950’s.</p> <p>Further, on the intersection of High Street and Mouat Street, as part of the connection excavation to the existing water main, DM Civil uncovered the original Karri pavers that were used in the early 1900’s as the pavement for High Street and surrounding roads. These blocks of timber were dipped in hot tar and then installed on their ends and created an economical and long-lasting trafficable pavement for the Fremantle CBD. The tar prevented the timber from rotting and insect attack. Once the pavers were exposed, Archae Aus was immediately advised and all works ceased in the area until they were able to assess and provide guidance on what to do. It was decided that the pavers had significant heritage value and that they shouldn’t be disturbed. DM Civil were able to redesign the connection so that the pavers were not disturbed. Archae Aus catalogued the discovery and asphalt was placed back over the pavers for protection.</p> <p>CI renewal works, such as these, are considered extremely disruptive to the local community and businesses. Water Corporation and DM Civil both shared the view that Community Consultation was a significant and important aspect of the works and without this, the project would not be a success. Water Corporation had a community/stakeholder management team onsite for the duration of the works. They were the direct interface to the public and local stakeholders, providing accurate, well planned information to provide as much lead time as possible. This information was provided by DMC management team on a weekly basis and without this accurate and reliable information that reflected the proposed works for the following week(s), the community would quickly lose faith in the project in terms of achieving and delivering what was being stated.</p> <p>The Water Corporation and DM Civil also conducted community stakeholder meetings once a fortnight, where the community asked questions, requested clarifications and received information in general about the project. This allowed us to clarify and explain the sequencing of the works, the methodology required and why in some instances certain activities took longer than others. This proactive approach with the community, where the staging of the works, the timing of the works, details around how the construction would be completed made a significant positive difference to the delivery of the project. When the community was being heard and kept in the loop on how the works were progressing, there was a real positive sentiment and feedback.</p> <p>DM Civil delivered a broader range of diverse services to this complex project. Extending our capabilities beyond our <a href="https://dmcivil.com.au/capabilities/pipelines/">pipe laying</a> and <a href="https://dmcivil.com.au/capabilities/trenchless-technology/">trenchless</a> methodologies, we completed 90% of the works using our own internal workforce and machinery.  Specialised activities such as HDD Installation, PE Welding and Asphalt and Profiling were completed by sub-contractors, closely managed by DM Civil’s team.</p> <p>Our self-performing capabilities continue to showcase why the Water Corporation approach us for complex, highly integrated work scopes. DM Civil are proud to have helped secure the reliability of water to customers in Fremantle and the surrounding areas for decades to come.</p> Thu, 28 Jan 2021 09:28:26 +0800 https://dmcivil.com.au/news/pipes-for-fremantle/ Replacing Centuries of Drains https://dmcivil.com.au/news/replacing-centuries-of-drains/ <p>In the process of completing Main Drainage Upgrades within the heart of Fremantle, DM Civil uncovered a rare glimpse of drainage history. An 1800’s two foot by eleven-inch timber box drain used as the way to remove stormwater off the street and out to the swan river, solving a severe sanitation issue at the time. The timber box drainage line was decommissioned when the 675RC main was installed in early-1900’s which DM Civil is now upgrading in 2020/21. It is safe to say that design has come a long way from the timber drainage line, however the longevity of the timber was remarkable even under a major roads loading. The dedicated Archaeologist team took over and recorded the find before the State’s Heritage Department gave DM Civil the green light to remove and install our new drain.</p> <p>DM Civil have completed 130m of 900RC pipes and 100m of 1800x900 Reinforced Box Culverts with a tie-in to an existing chamber to create a new outlet to the harbour. The works completed have been done to an extremely high quality and DM Civil are proud to now be connected with this piece of history for many more centuries to come.  </p> <p>We will return in the winter of 2021 to complete another complex part of the works at the railway crossing.</p> Fri, 04 Dec 2020 10:27:48 +0800 https://dmcivil.com.au/news/replacing-centuries-of-drains/ Investing in new grout equipment at DM Civil https://dmcivil.com.au/news/investing-in-new-grout-equipment-at-dm-civil/ <p>DM Civil continues to reinvest in its company owned equipment. Recently, the Trenchless Technology division purchased a new grout pump. The design and procurement of this pump is to meet any changes to client grout specifications used for filling the annulus between pipes and casings in our trenchless technology works.</p> <p>It is a 3 Phase 415V 7.5 kW (10HP) Abarque HD50 Peristaltic Hose Pump. A Peristaltic pump is similar in operation to the pumps used on concrete pumping units.</p> <p>It has a fixed position rubber hose that is curved around a 360-degree arc, with the suction at the top and discharge down the bottom. It is classified as a positive displacement pump and in particular a progressive cavity pump.</p> <p>This pump purchase is in response to market requirements moving away from the traditional gravity fed borehole slurry mix that has been used over the last three decades, to now a sand and cement based pumped grout mix. This mixture flows poorly under its own weight by gravity and therefore requires a pump like this to push the grout into the annular cavity under pressure. This pump will allow DM Civil's <a href="https://dmcivil.com.au/capabilities/trenchless-technology/">Trenchless Technology</a> Division to meet any new client specification requirements.</p> Fri, 30 Oct 2020 10:45:58 +0800 https://dmcivil.com.au/news/investing-in-new-grout-equipment-at-dm-civil/ DM Civil Steps Up Training Opportunities https://dmcivil.com.au/news/dm-civil-steps-up-training-opportunities/ <p>In line with our peak industry body, the Civil Contractors Federation WA (CCFWA), DM Civil continues to offer <a href="https://dmcivil.com.au/about/training/">training opportunities</a> to our staff. CCFWA is lobbying our state government to consider re-classifying Certificate III Civil Construction traineeships to apprenticeships. This is a part of an effort to raise the status of civil construction training to that of building and mechanical trades that have historically enjoyed a higher profile than our operators, drainers and crew supervisors.</p> <p>The decline in the number of trade apprentices being engaged in recent years coincides with the drop off of business activity. This could also be seen as a failure of government policy on both sides of politics to maintain this important training ground and has a negative effect on all industries including civil construction. The lack of trained and qualified tradespeople and what this means for Australia as a nation and for us, the civil construction industry, will result in a severe shortage of talent and that shortage may be starting now. The hard times that Western Australian business has endured has meant that the industry has been unable to maintain staff training positions, let alone remain solvent in so many cases.</p> <p>DM Civil has always maintained a policy of adding people at a junior or untrained level and relying on our experienced core staff to support and nurture the talent that these newcomers bring to us.</p> <p>An example of our trainee scheme is our apprentice boilermaker/welder, Brennan. Brennan has been with DM Civil since November 2018 and is being trained by our steel fabrication team under Adam and Craig. Adam is our lead boilermaker/welder and is in charge of fabrication for our projects including our <a href="https://dmcivil.com.au/capabilities/trenchless-technology/">trenchless</a> division work. Both Adam and Craig take on the responsibility of assigning work to Brennan and overseeing his progress while providing task specific training to help this young apprentice progress on his path to becoming a qualified tradesperson in years to come. This hands-on training under experienced tradesmen is essential to teaching our youth the correct techniques for welding and fabrication duties. This applies to the craft itself and as importantly, the work ethic that is required to properly fulfil the duties of a tradesperson.</p> <p>Since joining DM Civil after completion of his high school studies, Brennan has progressed in his short time with us to become a useful member of his team in the fabrication workshop. As an example of his progress to date, Brennan is showing the capabilities required for refurbishing auger flights that have been misshapen during the trenchless division’s bore and jack operations. This required heating and reshaping of the auger flights back to their original level and alignment and grinding back the leading edges after manipulation to ensure the continuity of the spiral.</p> <p>Another recent example of Brennan’s progress was his work on refurbishing a set of 3 kibble frames, originally configured for mining operations. The kibbles were first disassembled and stripped back to bare metal. Then, new stop gates, lever connections, handles and springs were designed and fabricated in house to render the units as working kibbles with their new designs to suit our field operations. After a coat of paint, the kibbles are now fit for work and in use for our field crews. The refurbishment of these kibbles, which were destined for the scrap heap, are a fine example of the value of having in-house capabilities to design, fabricate and repair our own equipment. This capability extends to all areas of our plant and equipment fleet and is applied to our mechanical workshop with its staff of fitters and technicians.</p> <p>We are proud to have Brennan in our team of tradespeople and we encourage him and our other apprentices and trainees to progress and we wish him luck in completing his studies and internship to become a qualified tradesperson.</p> Sun, 16 Aug 2020 23:40:08 +0800 https://dmcivil.com.au/news/dm-civil-steps-up-training-opportunities/ 2020 CCF WA Awards https://dmcivil.com.au/news/2020-ccf-wa-awards/ <p class="p1">DM Civil celebrates the award of Project Manager of the Year to our own Grant Craven. The Civil Contractors Federation of WA judging panel has selected Grant Craven from a strong group of finalists who also have substantial experience and credentials in the delivery of civil projects.</p> <p class="p1">Grant started working at DM Civil in 2001 as a graduate civil engineer, not long after graduation from Curtin University. His journey with the company began on work sites like the WA-21 Woodman Point Wastewater Treatment Plant upgrade, a 150-million-dollar Water Corporation project. This project was managed on site by DM Civil’s Jack van Bemmel. Jack was one of Grant’s project management mentors on major projects like WA-21 and the Canning Vale Type 180 wastewater pumping station. Grant also served a long period of mentoring under Martin Hicks on projects like Samson Brook trunk main, Coral Bay Water Supply Upgrade and Karara Water Operations. Grant went on to manage projects on his own including Bungaroo Pipeline Replacement and he is currently in charge of our Cast Iron Replacement programme or Pipes for Perth. During all of his time since joining the company, Grant has been mentored by our General Manager of Engineering, Bruce Shaw. Grant and Bruce worked together to a point where Grant achieved his status of Chartered Professional Engineer with Engineers Australia.</p> <p class="p1">In recent times, Grant was elevated to his role of Projects Commercial Manager, which encompasses control of the DM Civil engineering group to reinforce the role that engineers, and project managers fulfil within the company to, in turn, increase the performance of the group within the company structure. Grant’s two decades of experience in site project engineering and his performance in that role, made him an obvious choice for this office.</p> <p class="p1">Grant has excelled in the role because he has seized the opportunity to better organise the group and the processes under his control. He has achieved this success partly through his own hard work in planning and organisation and partly by mentoring his group to allow them to grow professionally and by pushing them to maximise their opportunities and capabilities. This has become a self-perpetuating process that increases efficiencies in his own department and in the company as a whole.</p> <p class="p1">Grant has a natural individual style of leadership. Over his years of involvement in project management on site and in the office environment, he has developed his own techniques engaging with his staff to ensure that they understand their roles and in encouraging them to perform to their best in delivering successful outcomes. Grant has also developed what is a natural eye for detail in the key requirements of a project and the challenges that need to be addressed and overcome to succeed in delivering the completed contract requirements. His ability to judge people and personalities has increased over time. This has allowed him to deal with clients and other stakeholders such that what may have been a disjointed relationship, becomes a collaborative relationship where all parties can acknowledge a win/win outcome. These attributes are not necessarily a given quality, and Grant can take credit for creating his own success in this area.</p> <p class="p2"><strong>Master of Business Administration Degree</strong></p> <p class="p1">Grant undertook this course, largely in his own time, for the enhancement of his understanding of the requirements to running of a business, relevant to DM Civil. This gave him a good understanding of all the roles associated with his own that must be executed effectively in order for a business to survive and thrive in the current commercial climate. Some of the lessons learnt through this degree are evident in the way that Grant fulfils his role.</p> <p class="p2"><strong>Board of Management</strong></p> <p class="p1">For many of the same reasons that he was elevated to his core duty as Projects Commercial Manager, Grant was chosen to be a participant on our <a href="https://dmcivil.com.au/about/board-of-management/">DM Civil Board of Management</a>. This role is carried on top of his core duties as the Projects Commercial Manager and also the individual contracts that he project manages. Participation at board level has undoubtedly led Grant to grow in all roles because he is able to see and actively contribute to company direction.</p> <p class="p1">We congratulate Grant on this achievement and his well-deserved award in front of his peers. He is a fine example of the professional that we all aspire to be.</p> Mon, 06 Jul 2020 12:40:44 +0800 https://dmcivil.com.au/news/2020-ccf-wa-awards/ DM Civil’s Tesmec TRS 1475 Trenching Rock Saw essential equipment for mine pit https://dmcivil.com.au/news/dm-civils-tesmec-trs-1475-trenching-rock-saw-essential-equipment-for-mine-pit/ <h2><div class="media leftAlone"><iframe width="459" height="258" src="https://www.youtube.com/embed/op7njAzD6Jk?feature=oembed" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen=""></iframe></div></h2> <p>DM Civil were initially contracted to undertake several kilometres of drainage trenching surrounding a mine pit dewatering pond at amine site in the goldfields using DM Civil’s 95 tonne 600HP Tesmec TRS 1475 Rock Saw.</p> <p>The existing near surface material was extremely hard and site management were extremely impressed with both the machine’s performance and also the our crew’s work ethic.</p> <p>Senior mining engineers recognised that the use of the Tesmec TRS 1475 may help with excavation works as part of the primary development of a new lift shaft infrastructure.</p> <p>The key issue was that the hardness of the subsurface material and confines of the work between existing stockpiles, mine pit haul road and mine site offices in the near vicinity precluded the standard drill &amp; blast and bulk excavation methodology.</p> <p>This standard approach would be too invasive to the mine’s operations and with potential harm to nearby existing infrastructure</p> <p>Discussions between the mine and DM Civil resulted in a team collaborative approach to an extremely tight excavation, utilising the Tesmec TRS 1475, plus 36 tonne excavators and 30 tonne front end loaders.</p> <p>The methodology was to undertake slot trench excavation, up to 3 metres deep then backfill and compact immediately to allow the next slot trench pass to be within 300mm of the previous excavation.</p> <p>The works was to be undertaken included in 5 different flitch (box-out) levels. ,By  with gradually reducing overall perimeter sizes, to a depth of approximately 13.5 metres and with an 8 degree entry/exit ramp approximately 100 metres long left in place for access to future raise boring and concrete works.</p> <p>Location, orientation, overall cut shape and time were all essential elements of the proposed earth works, with overseas specialty drilling, grouting &amp; and raise boring contractors scheduled for mobilisation in advance of the earthworks being completed.</p> <p>DM Civil mobilised two (2) teams of personnel to undertake 24 hour shift operation.</p> <p>DM Civil in-house survey teams uploaded excavation design and individual trench cut route alignments into a GPS base station, which was linked with the Tesmec TRS 1475 GPS system.</p> <p>This produced extremely accurate position, orientation and depth control essential to create a level and flat base for each flitch for the Tesmec TRS 1475 to undertake the next batch of slot trenches.</p> <p>The 300mm wide by 3000mm deep “biscuits” of hard material left between each slot trench cut were easy work for DM Civil's Cat 336EL excavators to snap off when undertaking the bulk earthworks.</p> <p>DM Civil's Cat 980 front end loader was the “War Horse” that uploaded and carted excavated material back up the ramp to a stockpile.</p> <p>The trenched material was excellent material was, free of rock boulders because of the chain saw trenching process and was therefore later re-used as valuable backfill. to This was placed and compacted to fill a disused pond at the location of one of the shaft A-Frame back-brace footings.</p> <p>The operation of trenching, immediate backfill, re-excavation, loading and carting of material to a stockpile was undertaken using a mixture of 12 and 24 hour shifts over a 14 day period.</p> <p>During this time DM Civil also worked in conjunction with specialised drilling and soil anchoring contractors, who installed rock bolts and soil anchors to the vertical sided pit excavation walls.</p> <p>The mine management was extremely pleased with the quality of the finished product, timeliness of the operation and importantly ability to re-use valuable trenched material that would otherwise be drill and blast boulder waste.</p> <p>The GPS control to the Tesmec TRS 1475 allowed peg-less survey control of the excavation, which aided in the overall safety of the operation without the need for ground based survey personnel in the near vicinity of very large earthmoving machinery, with restricted visibility.</p> <p>Trenching machine productivity and GET (Ground Engaging Tool) performance were greatly enhanced through the use of construction water, which also aided for trench backfill compaction and also pre-conditioning of the excavated material for subsequent re-use for the A-Frame footing earthworks. This also had the added benefit of controlling dust during the earthworks.</p> <p>Overall, whilst the Tesmec TRS 1475 with its GPS control was essential to deliver the required project outcomes, ultimately, the teamwork between mine management, &amp; staff and DM Civil personnel that guaranteed its success. The excellent use of interpersonal skills and cross fertilisation of ideas and solutions to problems, as they arose on site, was testament to the “Can Do” approach of both organisations and a truly rewarding experience for everyone involved.</p> <p>The Tesmec TRS 1475, showcased in this video, was an essential element in delivering a successful outcome for this highly integrated project.</p> Fri, 19 Jun 2020 10:03:31 +0800 https://dmcivil.com.au/news/dm-civils-tesmec-trs-1475-trenching-rock-saw-essential-equipment-for-mine-pit/ DM Civil’s War Horse - Cat 980G front end loader https://dmcivil.com.au/news/dm-civils-war-horse-cat-980g-front-end-loader/ <p>DMC owns and operates a Cat 980G front end loader. It is an often forgotten, unassuming and at times maligned item of plant.</p> <p>The Cat 980G has recently been in regular daily, plus night shift use for loading and carting excavated rock from our works at a mine near Leinster.</p> <p>The excavation is a part of infrastructure work to develop a new vertical head frame access shaft, rather than access via the current open pit and tunnels for the extraction of the resource. </p> <p>Our <a href="https://dmcivil.com.au/capabilities/trencher-hire-and-services/tesmec-trs-1475/">Tesmec TRS1475</a> rocksaw has excavated, via a unique method of sequenced trenches and floors, approximately 15,000m<sup>3</sup> of rock to a depth of 13.5m.</p> <p>Two Cat 336EL excavators were used to excavate and stockpile the trenched material on each box-out floor, for the Cat 980G loader to uplift and cart up a ramp and stockpile for later use.</p> <p>The stockpiled material is now being used as backfill in a disused turkeys nest dam, which is at the location of one of the proposed two mammoth concrete footings for the head frame backstays, approximately 200 metres away.</p> <p>Our Tesmec TRS1475, was fitted with its new GPS monitor and linked to a survey base station, which was uploaded with the pit excavation design, with alignments and depths of all cuts. It has done a magnificent job and will be of tremendous benefit in the future for peg-less position, orientation and depth control, particularly on “graded” pipelines.That however is another story for another day.</p> <p>The other stand-out star, which DMC site personnel have nick named “DMC’s War Horse” was the Cat 980G, which has outperformed all expectations on site and also some in the office. It has been the perfect machine for this job. The Cat 980G picks up a whopping 5.4m<sup>3</sup>, nearly 10 tonnes of rock, 13.5 metres below the surface and carts it up a 100 metre long ramp, with an incline of 8 degrees, in its stride, only to return and do the same thing again and again on a nearly full time cycle. This is during a 12 hour day shift and then, after refuelling, grease and maintenance check, straight into a 12 hour night shift. </p> <p>Many team members at DM Civil consider the loader slow; however in every one of the 4 gears the Cat 980 is up to 6% faster than the same gears in our new Cat 950H loaders. One bucket load in the Cat 980G is 5.4m<sup>3</sup> compared to 2.9m<sup>3</sup> for a Cat 950H.</p> <p>Due to the cycle time of manoeuvring, loading, manoeuvring and dumping the Cat 980G far outstrips the performance of two Cat 950H’s. This is because, for every one bucket load of the Cat 980 there is approximately 30 seconds spent in these loading and dumping moves compared to two 30 second cycles for the equivalent with two Cat 950H’s, plus the near equivalent travel speed.</p> <p>Robert LeTourneau, who was born in 1888 and died in 1969, was arguably the world’s most prolific inventor of earthmoving machinery, particularly extremely large earth moving equipment. He was famous for his saying: “The secret to success in the earthmoving business was having the cheapest dollars per cubic yard of dirt moved.” This comment is still valid today as demonstrated above. </p> <p>DM Civil’s Cat 980G moved material 36% cheaper than if we had used two of our latest Cat 950H’s. On this latest project, it has been estimated that DM Civil saved our client $36,000.00 by using DM Civil’s “Old and Slow” Cat 980G, instead of two “New and Fast” Cat 950H’s.</p> <p>We ask everyone at DM Civil to reconsider, that often sometimes what is thought and at times said, is not necessarily the truth. It’s only when you are prepared to challenge your thinking and look at the facts that you will discover the real truth. This is probably the lesson to be learnt from this particular project.</p> <p>The Cat 980G has performed faultlessly, in extremely high heat and arduous conditions and is truly worthy of recognition as DM Civil’s War Horse.</p> Fri, 17 Apr 2020 08:05:21 +0800 https://dmcivil.com.au/news/dm-civils-war-horse-cat-980g-front-end-loader/ Kambalda DN375 Sewer Replacement and Associated Works https://dmcivil.com.au/news/kambalda-dn375-sewer-replacement-and-associated-works/ <p class="Pa0">The Kambalda West sewer network was constructed by Western Mining Corporation in the 1970’s. The sewer main was constructed with asbestos cement (AC) pipe but the 150m replacement section, which is to be constructed in a floodway is above ground and to be constructed from GRP pipe. Additional works for this project are replacement of two dilapidated stormwater culverts and the upgrade of the existing access track.</p> <p class="Pa0">We have now completed the second swing for the works following the Christmas shutdown with practical completion carried out on 28 January. We will spend a third part swing beyond this to complete miscellaneous works additional to the original scope.</p> <p>The project required the fabrication of a stainless steel sluice gate (penstock) and weir upstream of the works. The penstock design drawing supplied had insufficient detail to fabricate the unit without making several assumptions. DM Civil designed and detailed this unit in-house in order to provide enough detail for our supplier to produce a workable unit. The shop drawing was produced by our in-house draftsman. The access chamber has a bifurcation to both the treatment works as well as to an emergency overflow pond.</p> <p>Another issue that required special attention was the connections between the existing AC pipe, the existing PVC pipe and the new GRP pipe. Custom made level invert tapers were required in the correct size to allow for ductile iron connectors to be used at these interfaces. Our engineering manager, Bruce Shaw, was consulted by the project team to provide his experience and expertise in this area. Bruce’s previous experience as a pipeline and pump designer at Hardie Pipelines gave us exactly the advice needed for this task. His wealth of knowledge avoided costly mistakes being made with pipes produced so long ago that have some characteristics unknown to modern designers and field staff.</p> <p>The design of the GRP pipe required the procurement of 12m lengths to maintain stiffness for the above ground section, which is supported on steel pipe cradles. It was through the purchasing department that we were able to call upon a long time supplier to provide a special run of this non-standard length to be ready on time and to keep on schedule. </p> <p>No regional project can be completed without thorough planning for materials delivery. Plans and orders of all materials were through our purchasing department. Almost all machinery and materials were conveyed by our own trucks through the transport and logistics department. Our team made several trips back and forth to ensure that deliveries were made reliably, on time and using our own resources.</p> <p>An essential part of working in regional areas is to satisfy the requirements of the local operators. The region is based at the wastewater treatment works, only a few hundred metres downstream of the works. This allowed our crew to liaise directly with the local staff to fine-tune the installation of components such as the penstock. This was installed upstream of the works into an existing access chamber. After on-site discussions between DM Civil and the local operator, we received a request from head office to install a second penstock to enable isolation of both channels in the bifurcated access chamber.</p> <p>The existing asbestos cement (AC) pipework was in a dilapidated state and except for the above section being replaced by DM Civil, this pipework had been relined with a spiral wound plastic. Despite this refurbishment, care was needed working around the pipe to avoid breaking away fragments or puncturing the plastic lining. The scope of works originally required the placement of fill material over the existing AC pipe to a minimum cover followed by compaction. DM Civil clarified that we made no allowance for this compaction because of the risk of pipe failure. As a departure from the scope, we have placed fill material around and over the pipe and coated this with ballast material to guard against soil erosion from wind and rain.</p> <p>The project has been a great success and a credit to the construction crew and our office based support. The client has thanked us for producing an upgraded asset delivered on time and under budget with little requirement for direction or management throughout. DM Civil’s adaptive in-house capabilities, diverse long-standing experience and hands on approach ensured project delivery and highlighted our ability to provide tailored, sustainable civil contracting solutions to regional Australia.</p> Wed, 12 Feb 2020 11:52:48 +0800 https://dmcivil.com.au/news/kambalda-dn375-sewer-replacement-and-associated-works/ Successful completion of water infrastructure contract https://dmcivil.com.au/news/successful-completion-of-water-infrastructure-contract/ <p>In March 2018, DM Civil became involved in an ECI (Early Contract Involvement) contract to be part of the upgrade Armadale Road from Murdoch Drive to Nicholson Road, including a major over-pass bridge at Nicholson Road.</p> <p>Initially the works for DM Civil was to replace sections of the existing DN1370 &amp; DN1220 Serpentine Trunk Water Main, which feeds Perth with water from Serpentine Dam. This was to be done with new DN1400 Sintakote® cement lined steel pipe, in stages, on planned shut downs. This was critical work, which required considerable, design, planning, scheduling, coordination and management throughout the works, whilst working in with other construction workers building the new overpass and relocating and replacing other services with new infrastructure.</p> <p>DMC commenced work on site on the DN1400 mains on the 6th July 2018.</p> <p>On completion of the DN1400 Serpentine Main upgrade works, DM Civil was awarded additional and new critical water infrastructure works, being completed 18 months later in December 2019.</p> <p>The last items of work was the construction of a Pressure Regulating Valve (PRV) building near the intersection of Nicholson and Warton Road.</p> <p>DM Civil constructed the new above ground DN400 &amp; DN200 PRV valve station; however due to its proximity to local residences and the noise generated from the continuously operating PRV’s required to be enclosed with an acoustic building to mitigate the nuisance sound.</p> <p>Like all the other works on this design and construct contract, speed of construction, through anticipation of design and prior planning for bespoke components were a necessity to bring the works to a successful completion, on time and also on budget.</p> <p>The PRV building was constructed utilising precast concrete tilt up panels and pre-fabricated streel roof truss frame.</p> <p>This facilitated a speedy on site construction; however dimension control of the tilt-up panels and also the structural steel roofing was critical to ensure this was done properly, once and without re-work.</p> <p>The PRV building included some unique features:</p> <ul> <li>Architectural texture banding to sections of the external wall panels;</li> <li>Two weather &amp; sound proof removable roof hatches to allow later removal, repair and maintenance to the PRV’s;</li> <li>Roof acoustic insulation;</li> <li>Acoustic ventilation louvres;</li> <li>Solid acoustic steel clad doors;</li> <li>Full-surround acoustic door seals.</li> </ul> <p>We worked closely with our client to organise, coordinate and manage specialised contractors, on a best for project basis, to provide a successful outcome on time, budget, quality, environment and safety.</p> <p>The PRV building was a culmination of a highly successful business relationship to bring all the important new water supply infrastructure on line to allow the new Armadale Road to be opened to the public for use on time.</p> <p> </p> Fri, 31 Jan 2020 13:29:37 +0800 https://dmcivil.com.au/news/successful-completion-of-water-infrastructure-contract/ Nicholson Road PRV Building – Not All of DM Civil’s Work Gets Buried https://dmcivil.com.au/news/nicholson-road-prv-building-not-all-of-dm-civils-work-gets-buried/ <p>We certainly have a diverse range of capabilities and this is not limited to just complex pipeline projects. DM Civil were commissioned to construct a building to house the above ground mild steel cement lined (MSCL) pipework and pressure regulating valves (PRV’s).</p> <p><br>The PRV pipework and valve station are all part of the services relocation work DM Civil have been undertaking at the intersection of Nicholson &amp; Armadale Roads, over the last 18 months.<br><br>The water supply connection is for Hakea Prison and with continual operation of the PRV’s, there was a noise pollution issue with adjoining properties, which was resolved by the construction of the PRV building to enclose the valves and deaden the noise.</p> <p><br>The building incorporates a number of acoustic control devices and features, such as, acoustic ventilation louvres, which allow air movement through the building; however traps noise. The three access doors are made from solid timber, with complete metal cladding and fully sealed around the door perimeter to prevent noise escaping. The roof and ceiling space is fully filled with two layers of acoustic insulation up to 200mm thick to prevent noise escaping.</p> <p><br>A feature of the roof is that it has two removable hatches to allow future craneage of the valves for repair &amp; maintenance work. The removable hatches have full perimeter rubber seals for both weather proofing and acoustic properties. The building is constructed using pre-cast concrete wall panels, which feature external texture banding cast into the upper part of the walls.</p> <p><br>Our in-house engineers created detailed fabrication drawings for the structural steel roof and pre-fabrication was in our metal fabrication workshop to match with the building program and concrete wall panel construction. Tight dimension control was crucial to a successful outcome. DM Civil procured numerous specification driven specialty components used in the building, some from inter-state and others from overseas.</p> <p><br>The prefabricated concrete walls were erected in early November and currently the structural roof components, roof cladding, brick &amp; plaster work, ceiling fixing, external concrete pavement and door installation are complete with only the painting and anti-graffiti coating remaining, which will be complete in the first week of December.</p> <p>Attention to detail, planning, scheduling, prefabrication and coordination have allowed for a rapid site build and a structure which will stand to serve our client and the community for many years.</p> Mon, 02 Dec 2019 10:23:15 +0800 https://dmcivil.com.au/news/nicholson-road-prv-building-not-all-of-dm-civils-work-gets-buried/ Rottnest Island Wastewater Pumping Station, Sewer Replacement and Pressurised Fire Main Upgrade https://dmcivil.com.au/news/rottnest-island-wastewater-pumping-station-sewer-replacement-and-pressurised-fire-main-upgrade/ <p>DM Civil was engaged in April 2019 by Rottnest Island Authority in a contract to construct a new wastewater pumping station (WWPS) and sewer reticulation on Bedford Avenue in the main settlement. The requirement for this infrastructure upgrade was driven by the plan to expand the existing Hotel Rottnest by adding an 80 room accommodation wing overlooking Thomson Bay. This work is currently underway by the builder and provided a critical date for commissioning of the WWPS.</p> <p>The existing settlement is a congested mix of holiday accommodation units, commercial premises and a road network carrying countless tourists within the main hub and to and from the island’s other attractions. The existing underground infrastructure is an aging matrix of gas, electrical, bore water, potable water and communications pipework and wiring – the alignments and depths vary and do not necessarily conform to the rigid standards of utilities installed on the mainland. This is typical of some of the older areas of Perth and Fremantle where standards evolved since the early 1900’s and presents a challenge when installing new services.</p> <p>A key factor in the decision to award the contract to DM Civil was the demonstration of our capability to work in such an environment without interrupting the supply of these services. Rottnest Island is an important and growing tourist attraction for Western Australia. Even in the winter months, tourist numbers have proven to be high, partly because of the historic as well as natural attractions but also because our relatively mild winters are no barrier to international tourists. A unique natural feature of Rottnest Island is the Quokka population. These curious marsupials are gaining international fame since Roger Federer and several other famous identities posted ‘Quokka Selfies’ to the delight of their fans who now insist on the same when visiting the island. The proven ability to carry out our works without disturbing the island’s tourist traffic was another factor in the award of the contract to DM Civil. This was largely facilitated by our offer of cost-effective trenchless installation of the sewer main. Protection of the Quokkas by eliminating trenching and isolating drill pits with sand bags on fencelines as well as ‘Quokka Ladders’ as an escape contingency was seen as a big positive by the selection panel.</p> <p>The wastewater pumping station installation was another challenge. At over 5 metres deep, the base of the excavation would be in groundwater, which was approximately 2 metres below existing ground level. The excavation would need to be dewatered to allow for installation of the concrete structure and a strict rate of extraction of groundwater needed to be adhered to for compliance with Department of Water regulations. To limit the groundwater extraction rate, DM Civil proposed the use of a sacrificial steel caisson and a concrete plug as a contingency against base heave. The actual installation proved to be favourable in terms of groundwater extraction rates and only metal bedding was required, providing a programme shortcut. The pumping station was commissioned without incident and is now operating.</p> <p>A further scope of works awarded to DM Civil was the upgrade of the pressurised fire main. The existing main is limited in coverage and was originally a simple gravity feed, unsuitable for the growing resort. The new fire main configuration will increase coverage and reliability of the firefighting network. Installation of this network was also carried using <a href="https://dmcivil.com.au/capabilities/trenchless-technology/">trenchless techniques</a>, thereby virtually eliminating any interface with tourist visitors and bypassing existing services.</p> <p>DM Civil has succeeded in delivering this infrastructure upgrade in complying with the project quality scope and as importantly, in minimising disturbance to tourism, businesses and existing infrastructure. We look forward to successful completion in the coming weeks and a satisfied client.</p> Mon, 09 Sep 2019 09:51:54 +0800 https://dmcivil.com.au/news/rottnest-island-wastewater-pumping-station-sewer-replacement-and-pressurised-fire-main-upgrade/ HSEQ recertification https://dmcivil.com.au/news/hseq-recertification/ <p>DM Civil are pleased to achieve recertification to ISO 9001:2015 for Quality and ISO 14001:2015 for Environment.  We also successfully transitioned to ISO 45001:2018 for Occupational Health and Safety, having previously held AS/NZS 4801:2001.</p> <p>We achieved our first <a href="https://dmcivil.com.au/about/health-safety-environment-and-quality/">quality assurance accreditation</a> to AS 3902 back in 1994 and upgraded to AS/NZS ISO 9001:2000 in 2003.  In 2007 we gained accreditation to AS/NZS ISO 14001:2004 for Environment and AS 4801:2001 for Safety.  Having evolved over that period, our integrated management system (IMS) had become very mature. </p> <p>Being able to align all three management systems provides a real opportunity to strategically integrate our whole of business approach.  The flexibility to implement “fit for purpose” structures and processes allows for more efficient outcomes whilst still achieving compliance and continual improvement, suited to the business, not the standards.  Identifying opportunities and risks will become more effective by improving employee consultation and involvement in systems implementation.</p> <p>This is a company-wide achievement and we’d like to thank all employees for their participation during the 7 day audit process.

These projects were critical stages to the delivery of a main roundabout and fly-over bridge development.  </p> <p>As these pipeline works incorporated some of Perth’s main water supplies, Serpentine &amp; Armadale Trunk Water Mains, it was crucial to have early contractor involvement. DM Civil, collaborated closely with key stakeholders to develop extensive constructibility methodologies and establish clear planning, staging, sequencing and co-ordination for the roll-out of all services, including:</p> <ul> <li>Comprehensive stakeholder management – a staged process to minimise disruption to local businesses, scheduling of works during peak water demand times, hazard prevention with high voltage power lines, high pressure gas mains and water reticulation mains to maintain the integrity of the water supply during construction.<br><br></li> <li>Pipeline design, replacement and construction logistics – a re-iterative process to establish the best suited alignment, pipe materials for the location, environmental sustainability and to minimise the disruption of existing infrastructure.    </li> </ul> <p>Our scope of works expanded as the project evolved and DM Civil were awarded:</p> <ul> <li>The replacement of 90m of the DN1220 &amp; DN1370 Serpentine trunk mains, replaced with DMN 1400 Sintakote® MSCL, under Armadale Road.

These types of microtunnelling machines utilise the slurry shield system and can operate in dry or water charged ground conditions.</p> <p class="Pa0">DM Civil has a current project to undertake an 80 meter microtunnelling bore under the Mitchell Freeway and Northern Transit Railway Lines. DM Civil proposed to utilise an Iseki TCS 900 Mixed Head microtunnelling Machine (MTM) with DN900 Reinforced Concrete Jacking Pipe (RCJP) to form a casing for the new DN700 Mild Steel Cement Lined (MSCL) bore collector pipe to be sleeved inside. The ground conditions of both sand and limestone required the use of a “Mixed Head” unit, which is Iseki’s “TCS” machine configuration.</p> <p>In order to match the dimension of the DN900 RCJP, the MTM had to undergo some reconfiguration to enlarge the cutting head to match the outside diameter (O.D.) of the RCJP. This was not an easy task, because rock and mixed head machines usually cannot be easily altered to suit different O.D. pipes.</p> <p class="Pa0">This is DM Civil’s largest Slurry Shield MTM to date with capability of bores up to approximately 1,200mm O.D. in mixed sand and hard rock up to 150 MPa in strength; i.e. 7 times harder than concrete. This machine can also crush rocks and boulders that enter the machine up to 200 MPa in strength; i.e. 10 time the hardness of concrete.</p> <p class="Pa0">Our workshop and fabrication shop, in coordination with the Trenchless Division, also built a new control building to house the machine controls. Whilst the MTM was disassembled the workshop undertook some improvements to the MTM to ensure the machine reliability was up to DM Civil’s requirements.</p> <p class="Pa0">DM Civil’s first became involved in trenchless technology over 35 years ago using auger boring machines (ABM) from America. Currently, DM Civil have a fleet of 4 different sized ABM’s capable of bores from DN300 to DN1600. These machines were complemented with the purchase of two guided boring machines (GBM), which accurately install pipes from DN150 to DN600.</p> <p class="Pa0">We moved into Microtunnelling to augment and complement the capacity of our ABM’s &amp; GBM’s with purchase Iseki and also Rockman MTM’s from Japan commencing in 2006. Over the last 13 years DM Civil’s Slurry Shield MTM fleet has grown and currently allows us to bore accurately in 9 different sizes from DN250 up to DN1200 in the complete range of boreable ground we encounter here in Western Australia, including wet ground and hard rock.</p> <p>The secret to our success and growth in this business is having a fully trained and experienced trenchless technology division team, plus, importantly, a qualified, experienced and trained in-house workshop and fabrication shop team. They are able to deal with all manner of maintenance, repairs and modifications to these highly complex machines, which utilise combinations of hydraulic, electric, mechanical and laser control componentry.</p> <p><a href="https://dmcivil.com.au/capabilities/trenchless-technology/microtunneling-earth-and-rock-/">Microtunnelling</a> is a very cost effective methodology used for bores under roads, railway lines, services and structures, in wet or dry ground conditions, where line, level and grade are critical. Our range of trenchless solutions allows us to provide flexible alternatives and methodology combinations to install infrastructure varying from DN150 to DN1600 in any ground conditions.</p> Thu, 20 Jun 2019 14:51:40 +0800 https://dmcivil.com.au/news/dm-civils-microtunnelling-fleet-has-grown/ Mount Street Trunk Water Main Replacement https://dmcivil.com.au/news/mount-street-trunk-water-main-replacement/ <p class="p1"> </p> <p class="p1">We have now reached a milestone in the Mount Street contract for Water Corporation. </p> <p class="p2">Our scope of works includes the replacement of a segment of the main water feed into the Perth central business district. This element being the DN900 steel water main that was laid in the northern road pavement lane from the lower end centre island up the hill and into Kings Park land. The scope of works also included the replacement of the reticulation mains which ran on both sides of the dual lanes in the verge. </p> <p class="p2">The new configuration feeds all buildings on both sides of the road from a single DN375 PVC main, also laid in the northern road pavement lane parallel to the DN900, but at a shallower level. The new design of the reticulation to the buildings is similar to our recent cast iron replacement schemes where we charged the new main after a short shutdown and proceed to change over services individually with very short shutdowns to the individual properties. </p> <p class="p2">In keeping with our originally proposed methodology, we now have an operating reticulation system that will be kept in service for the duration of the remaining works, except for a shutdown during the DN900 main connection. This sequencing of the works is designed to mitigate the risk of a water outage to the local residents and businesses and was an important innovation in our original tender submission. </p> <p class="p3">The initial challenge for DM Civil was the negotiations with City of Perth to reach agreement on the pruning of the boulevard trees planted on the verge and centre island. These were Queensland Box (Lophostemon confertus) and Jacaranda (Jacaranda mimisifolia) trees, essential to the amenity of the area. After extensive consultation with registered arborists, the City of Perth’s term contractor was used to appropriately prune the overarching trees in accordance with approved procedures and to the satisfaction of City of Perth. There were 70 trees to be considered. The result is an enhanced grove of trees in keeping with the most photographed area of Perth City. </p> <p class="p1">Reinstatement of the road pavement was required for the full width of the Mount Street northern carriageway. Compaction and levelling on the steep grade was a difficult task. However, the standards were achieved and the finished product has proven to match and exceed the original pavement. </p> <p class="p1">An excellent example of value adding for the contract was the decision by DM Civil to construct the DN900 distribution main using trenchless techniques under the traffic roundabout at Cliff Street and existing vegetation located within the Kings Park grounds. This was carried out by the trenchless division and provided at no additional cost to the client. The benefit to Water Corporation, Botanical Parks and Gardens Authority, the local residents and the public including tourists, was a continuous traffic flow and retention of high value trees in our world class park. </p> <p class="p1">One of the tender requirements was to demonstrate a record of stakeholder management in high density and politically sensitive environments. DM Civil has a good reputation in this area and this was certainly relevant to being chosen to bid on the project. To date, the project has not received any adverse press or on-site complaints. In fact, we have received positive feedback throughout the project process. </p> <p class="p1">Due to the original delay in the award of contract and possession of site, the construction programme was pushed into the summer period. The security of critical water supply to the CBD during the summer months required the postponing of the tie-in process for the DN900 main. This is now scheduled for the autumn months where demand will be reduced to the point where contingency supplies can be back-fed from the network. </p> <p class="p1"><span>Discover how our <a href="https://dmcivil.com.au/capabilities/pipelines/">multi-disciplined capabilities</a> enabled us to deliver this complex scope of work.</span></p> Fri, 15 Mar 2019 15:05:31 +0800 https://dmcivil.com.au/news/mount-street-trunk-water-main-replacement/ Morooka MST 800E Modification - Pipe and Flat-Bed Tray Carrier https://dmcivil.com.au/news/morooka-mst-800e-modification-pipe-and-flat-bed-tray-carrier/ <p>DM Civil’s DN700 Neerabup Bore Main project poses a number of challenges. One of these challenges was delivery of 12 metre long, 2.0 tonne DN700 MSCL pipes along parts of the pipe route that won’t permit the use of road transport trucks. </p> <p><a href="https://dmcivil.com.au/about/our-company/">Our workshop</a> team developed a solution to modify our existing Morooka MST 800E rubber tracked tip truck to a pipe and also flat-bed tray carrier. Both the workshop and fabrication team collaborated to bring the modification to fruition, and you can see the end result in action as depicted in the header photo. </p> <p>All the new components are bolted for easy removal for re-fitment of the tip body when required. Various engine components required re-configuration to ensure they didn’t clash with the pipe when being carried. </p> <p>The Morooka is rated to 4 tonnes as a tip truck; however, with the addition of pipe cradles at each end of the machine and flat-bed platform, the machine is now rated to 3 tonnes in this new configuration. </p> <p>This modification will allow for the safe transport of the DN700 MSCL pipes and DN1500 scour valve pit components across rough terrain with restricted access and no turn-around for road trucks. The platform also allows safe man access to allow rigging a lifting sling to the middle of the pipe, or chains to precast concrete components.  </p> <p><a href="https://dmcivil.com.au/about/health-safety-environment-and-quality/">SEQ</a> has worked in conjunction with the workshop team to develop a JSEA for the correct and safe use and operation of the Morooka in this configuration. Drafted working drawings were supplied to an independent structural engineer to obtain rated capacity certification.  </p> <p>This is a brilliant innovation to allow more diverse use of existing plant and equipment and was an outstanding effort by all involved. </p> Mon, 17 Dec 2018 13:05:31 +0800 https://dmcivil.com.au/news/morooka-mst-800e-modification-pipe-and-flat-bed-tray-carrier/ Water Corporation’s Steel Pipeline design and construct contract awarded at Neerabup https://dmcivil.com.au/news/water-corporations-steel-pipeline-design-and-construct-contract-awarded-at-neerabup/ <p class="Pa0">We have now been awarded Separable Portion 2 of the Neerabup Bore Collector Main. Separable Portion 2 is the construction element of the 500m of DN500 and 3,500m DN800 <a href="https://dmcivil.com.au/capabilities/pipelines/steel-pipelines-/">steel pipeline</a> and follows on from Separable Portion 1 being the design contract. DM Civil will be utilising cement lined and polyethylene coated steel pipe (Sintakote MSCL) in welded, weld restraint and rubber ring joint configurations to complete this project.</p> <p class="Pa0">The critical path of the contract programme commences with a section of pipeline to be laid behind the Mitchell Freeway Eastern noise wall, north of Moore Drive and south of Burns Beach Road. The route of the main lies beneath Western Power high voltage distribution lines which will be de-energised during construction of this section of works. The shutdown period is relatively short which will require a solid effort from the crews to complete the works on time and remain on the construction program.</p> <p class="Pa0">The <a href="https://dmcivil.com.au/capabilities/trenchless-technology/">trenchless</a> portion also has its complexities. The diameter and ground conditions for microtunnelling are such that we have purchased additional components for our existing machine to ensure that the rock conditions are not an issue. There is a considerable lead time on these components which means that we are pushed to the back of the programme for these works. Added to the list of complexities is the task of entering the existing DN1800 concrete sleeve that terminates beneath the traffic lane of the freeway. This will require specialist soil stabilisation and careful attention to detail for the bore setup and monitoring process.</p> <p>We are proud to have been chosen as the contractor for what is a complex and time critical task. Water Corporation considered the award over a long period due to the contract risks, of which there are many.

This is credit to Murray Pich as workshop manager and his team of fitters for their dedication.<span class="Apple-converted-space"> </span></p> Wed, 17 Oct 2018 15:30:06 +0800 https://dmcivil.com.au/news/dm-civil-transport-fleet-management/ Supporting the Australian Men’s Shed Association https://dmcivil.com.au/news/supporting-the-australian-mens-shed-association/ <p class="p1">The Australian Men’s Shed Association (AMSA) is the body representing almost 1000 Men’s Sheds and is recognised as one of Australia’s largest male based community development organisations.<span class="Apple-converted-space"> </span></p> <p class="p1">While doing a bit of a spring clean, we came across some PPE that was excess to our requirements or no longer suitable for our industry, rather than dispose of these items, Russell Pember suggested we should contact “Men’s Shed” and offer the PPE to them.<span class="Apple-converted-space"> </span></p> <p class="p3">AMSA was established in 2007 and funded by the Federal Department of Health.
