Cost Concepts provides various services during the construction process. One of these services is Change Order preparation and negotiation. The cause for change orders varies greatly, from change of design to unforeseen conditions. Cost Concepts prepares the change order estimate, which is even greater in detail than our final estimate. The change order estimate is in a labor/material format, complete with manhours and productivity breakdown. The detail serves as a tool, in order to control the contractor’s cost. Our team then goes on to negotiate with the contractor, producing a realistic cost for the change order.
