Lump Sum contracts often include limited audit rights and undisclosed contingencies.

• A. Lump Sum
• B. Cost Plus
• C. Target Price
• D. Unit Price

Answer: (A)

In a fixed-price lump-sum contract, the owner and contractor agree on a single price for a clearly defined scope, so the contractor bears most of the cost risk. Because the price is fixed, there’s less need to expose every actual cost through detailed cost accounting, and the owner often limits how deeply it can audit the contractor’s internal costs. The contractor, in turn, builds contingencies into the bid to cover unknowns, and those contingencies aren’t typically disclosed separately to the owner. That combination—limited rights to audit costs and hidden contingencies folded into the price—reflects the risk-and-reward balance of lump-sum arrangements, where price certainty for the owner comes at the contractor’s risk of cost overruns and reduced cost transparency. For contrast, cost-plus contracts involve open-book cost accounting with broader audit rights, since the owner pays actual costs plus a fee. A target-price approach blends a fixed target with incentives and shared risk, but doesn't typically conceal contingencies the same way. Unit-price contracts bill based on measured quantities, with ongoing cost data and audits more integral to how payments are determined.
