Allowance Contingency
What is Allowance Contingency?
Allowance Contingency, A budget reserve within construction allowances to cover unforeseen scope variations or price overruns.
Description
Allowance contingency is an additional percentage or fixed amount carried with an allowance line item to absorb unexpected cost increases, such as material price spikes, design changes, or quantity adjustments, before selections are finalized. Owners and contractors typically negotiate contingency levels, ranging from 5 to 10 percent of the allowance value. Proper tracking in the schedule of values ensures transparency; unused contingency is credited back at project closeout.
