What is the advantage of quoting an allowance for additional materials?

Quoting an allowance for additional materials provides flexibility for adjustments because it acknowledges that there may be unforeseen circumstances or changes in the project scope that require additional resources. This approach allows for a buffer in the budget so that if costs exceed initial estimates due to these adjustments, the project can continue without significant delays or complications. By incorporating an allowance, the contractor and the client can adapt to changes more smoothly, ensuring that the project can proceed efficiently even when modifications are needed. This flexibility is crucial in the dynamic environment of construction and fire alarm system installations, where changes often arise from various factors, such as design modifications or changes in building codes.
