Contamination Management For Earthworks At Major Infrastructure Projects

During major infrastructure projects, management of potential and actual contamination issues is an important part of the approvals, construction and closeout phases of the overall works program. Planning for contamination may save considerable time and expense with the consultants and contractors working to ensure any construction activities are protective of human health and the environment while maximising the re-use potential of materials. While management of soils, spoil and water is common place during the building of major infrastructure, the impact of contamination from past land-use, acid sulfate soils or fibrous cement sheeting fragments (containing asbestos) is less quantifiable, but no less costly if poorly managed.
