Residents were located on the North and Eastern boundaries of the work site. As a result, managing dust throughout the works was critical to minimise the impact on these residents. Through good construction practices and monitoring weather conditions, dust was never recorded leaving site and no complaints were raised for the duration.

The western half of the site contained loose sand to a depth of approx 3m. This material was unsuitable for building homes or services due to its relative low strength. Original option was to dig out this material, replace and compact in layers to meet geotechnical requirements. This would have been time consuming and expensive. DM Civil implemented an alternative compaction method called High Density Impact Compaction.

Using a specialised high impact roller, the 3m of loose sand could be compacted from the surface, providing the solid foundation required without any excavation and replacement of material required.

The new sewer reticulation was originally designed to connect with an existing main sewer at a depth of 6m. With the high water table, constrained site and for environmental considerations, the ground water extracted could not be disposed offsite. Through liaison with the consultant and Water Corporation, an alternative solution was found whereby an internal drop was used to connect with the existing sewer allowing the design levels to be brought up by approx 1.8m. This was significant in reducing the ground water encountered, reducing the environmental impact of the works.

An existing pre-school was operating at the eastern end of the site. To provide an event for the children, DM Civil organised a site visit where all the kids could get close access to the heavy machinery and see the works in action. This was the highlight of their week.

By providing alternative construction methods, implementation of new design principals, presenting strong community liaison skills and tight management structure, DM Civil ensured this project was a success for the client LandCorp.
