  3. Q3.Under a lump sum (fixed price) contract, who bears the risk of cost overruns?

    A.The project owner
    B.The architect or engineer
    C.The contractor
    D.The surety company
    CThe contractor

    Explanation: In a lump sum (stipulated sum) contract, the contractor agrees to complete the work for a fixed price.

Lump sum contracts transfer most financial risk to the contractor.

  4. Q4.What is a retainage in construction contracts?

    A.Advance payment made to the contractor before work begins
    B.A percentage of each progress payment withheld until project completion to ensure the work is properly finished
    C.The contractor's profit margin on materials
    D.A penalty deducted for each day a project is delayed beyond the completion date
    BA percentage of each progress payment withheld until project completion to ensure the work is properly finished

    Explanation: Retainage (typically 5–10% of each progress payment) is withheld by the owner until the project is substantially complete and all punch list items are resolved. It protects the owner by ensuring the contractor has financial incentive to finish and correct deficiencies.

  5. Q5.What does the term 'substantial completion' mean in a construction contract?

    A.The point when 100% of the work is finished with no outstanding items
    B.The stage when the work is sufficiently complete that the owner can use it for its intended purpose
    C.When the foundation and structural frame are complete
    D.When all subcontractors have been paid in full
    BThe stage when the work is sufficiently complete that the owner can use it for its intended purpose

    Explanation: Substantial completion is the date when the project is sufficiently complete for the owner to occupy and use it for its intended purpose, even though minor items (punch list) remain. It typically triggers the start of the warranty period, release of retainage, and the statute of limitations for claims.
