We typically see 5% in change orders on a project. This can be much higher if you aren’t realistic with expectations in the preconstruction phase. We build on a cost-plus basis; change orders are the same. We do not use them as a profit center, so the billing rate is consistent with the base scope. We prefer not to have them at all. They are a lot of work for everyone. Our specification process during preconstruction helps to minimize change orders. A contingency budget is built into the account to help plan on the unexpected. The project’s schedule is modified with each change order.
