Why are allowances and contingencies included in bid timelines?

• A. To inflate project costs unnecessarily
• B. To circumvent client approvals
• C. To account for long-lead items and potential schedule risks
• D. To conceal acceptable delays

Answer: (C)

Allowances and contingencies are included to account for unknowns and procurement realities in a bid timeline. An allowance sets aside a budget for items not yet selected or priced precisely, such as finishes or fixtures that the client will decide on later. A contingency provides a safety margin for schedule risks and potential cost overruns caused by long-lead items, supplier delays, fabrication challenges, or unexpected site conditions. By building these buffers in, the project can stay on track toward milestones even when orders take longer, substitutions are needed, or prices shift. They help keep expectations realistic and reduce the chance that late decisions or delays derail the timeline.
