Change orders over $500,000

Find change orders for our projects that are $500,000 or greater in cost.

When changes must take place in order to build the project as planned, we issue a change order to modify the original contract. This order directs the contractor how to handle the change, and also modifies the contract cost, plans and specifications as necessary. Oftentimes, these costs are included in the risk reserves for the project.
