While excavating on a project site, a contractor discovers hazardous chemicals buried a few metres below the surface. The project is delayed to allow for collection and disposition of the hazardous chemicals. Who would normally be expected to absorb these costs?

While excavating on a project site, a contractor discovers hazardous chemicals buried a few metres below the surface. The project is delayed to allow for collection and disposition of the hazardous chemicals. Who would normally be expected to absorb these costs?

• A. The owner.
• B. The contractor.
• C. The project manager.
• D. The regulator.

Answer: (A)

Unforeseen site conditions and hazardous materials are a risk that is typically owned by the project owner in standard contracts. When hazardous chemicals are found during excavation, the responsibility for remediation, disposal, and any resulting delays usually rests with the owner because they retain the budget and the scope for the project. The contractor performs the work as defined, and while additional costs for handling the hazard can be recovered through change orders, that reimbursement still comes from the owner’s budget rather than being absorbed by the contractor by default. The regulator enforces safety and environmental requirements, not funding remediation, and the project manager’s role is to oversee the process, not absorb financial risk. So, the owner would normally absorb these costs.
