ABSTRACT
As the design is being developed, engineers will continue to control costs by comparing actual and forecast values of engineering workhours and costs against the current estimate.
IV. 35% OF THE DESIGN COMPLETED At thirty-five percent completion of the design work, there will be more detailed information from the designer and the support team. At this stage, engineers may start utilizing information that was determined in the cost survey. They will know, exactly, what the wage rates should be for a given area. If they are going to use unit costing, or unit pricing in the estimate, they can start building this into controlling the costs. They may start using subcontractors, such as mechanical and electrical---often the largest subcontracts. The engineers may also go out to vendors for cost information, such as for special equipment. The 35% estimate is going to develop into a volume document with more information based on the design to date.
