Q

Describe the 2 ways that a contingency sum can be integrated into the project?

A

1) Within the Contract.

A contingency sum is sometimes included within the contract. In these instances, they are expended only by written instruction by the client.

2) Outside of the Contract.

Some clients prefer contingency sums to remain outside of the contract, and instead form part of the project cost. These costs should still be available for the architect to expend if required. This strategy means that the contractor isn’t entitled to margin on top of the contingency, and doesn’t see it as an opportunity to request variations.
