Abstract: Contamination on a construction site can lead to increased risk of unanticipated construction delays and increased costs. In response, some owners are opting for proactive approaches to handling contamination starting with the design stage. In many instances this involves preparing soil management plans as part of the construction bid documents. Thee Massachusetts Bay Transportation Authority's (MBTA's) Draw Number 7 Bridge Replacement project recently completed near Boston involved such planning to address contamination expected during excavation. Risks were allocated between the owner and contractor based on their source and the responsibility each entity had in managing those risks. This example illustrates key elements of that successfully executed contaminated soil management plan.
