If additional speakers are required beyond code, how should this be addressed in the quotation?

When additional speakers are required beyond what is specified by code, addressing this in the quotation as an allowance is the most suitable approach. An allowance provides a specific budget for additional items not initially included in the scope of work. It signals to the client that these additional speakers will incur extra costs, but it does not require a renegotiation of the original contract or budget.

By including an allowance, the contractor establishes a clear framework for how these additional needs will be met while keeping the project financially transparent. It helps ensure that there are funds reserved specifically for the additional speakers when they are needed, providing a proactive solution to potential code compliance issues.

While alternate prices and addenda are valid approaches for modification of existing contracts, they may introduce complexities as they would typically lead to renegotiation or changes to contractual terms. Failing to address the need for additional speakers completely would not be prudent, as it would leave the project open to non-compliance with code and potential future disputes over costs. Thus, including the need for additional speakers as an allowance is the most effective way to manage this situation.
