Which statement about contingency decreases as design detail increases is true?

• A. Contingency decreases
• B. Contingency increases
• C. Contingency stays the same
• D. Contingency is unrelated to design detail

Answer: (A)

Contingency acts as a reserve for unknowns. As design detail increases, the project becomes more defined—quantities, scope, and execution methods are clearer—so the likelihood of surprises drops. With fewer unknowns, the estimate is more reliable, and the cushion for unforeseen conditions can be reduced. Therefore, contingency decreases as design detail increases. The other directions would imply more uncertainty or no relationship, which doesn’t align with how risk and budgeting are managed when design detail improves.
