At the various stages of the project, quantities are estimated for structural elements. Standard check lists are used as guides to relate to the specific project.

Quinn Dressel Associates' in-house data bases on costing of recent projects are compared to costs for the region obtained from local sources, and unit rates established. Structural costs are developed to enable a reference comparison of prices by the costing consultant, and to establish the accuracy of structural prices at each cost control stage of the project.

A partner monitors the costing during the development of working drawings and keeps the team aware of the significance of structural development as they impact on costs.

There is an evolving process requiring co-operation between designers, cost specialists and the owner, to emphasize value analysis and to secure an improved and more economical structural system suited to local construction practices and availability of materials.
