When may a Lump Sum contract be least economical?

• A. When the scope is vague and undefined
• B. When detailed drawings and specifications are required
• C. When project duration is uncertain
• D. When material costs are fixed

Answer: (B)

A Lump Sum contract, which involves a fixed price for the entire project, may be least economical when the scope is vague and undefined. In situations where the project requirements are not clearly outlined, it becomes challenging for contractors to assess the effort, resources, and materials needed accurately. As a result, contractors may include a significant risk premium in their pricing to account for the uncertainties, leading to higher overall costs. In contrast, when detailed drawings and specifications are provided, contractors have clear guidance on the project requirements. This clarity allows them to offer more precise pricing based on known factors, which can lead to cost efficiencies. When project duration is uncertain, it can complicate the pricing and increase risks for contractors, but it doesn't inherently make a Lump Sum contract least economical. Fixed material costs provide stability in pricing, making it less relevant to the context of Lump Sum contracts and their economic efficiency. Therefore, the correct answer aligns more closely with the understanding that an unclear project scope will lead to higher costs, impacting the overall economy of a Lump Sum contract.
