Part of: Preparing for Construction in the 21st Century


During the last decade, efforts were directed towards improving constructability of highway design at Washington State Department of Transportation (WSDOT). This paper briefly summarizes previous constructability improvement activities at WSDOT based on the results from the interviews with both design and construction engineers in addition to various supporting documents. Change order review has been found to be a very effective way to extract construction knowledge. Valuable construction knowledge has been entered into a hypertext-linked Highway Constructability Improvement System (HCIS). It is not to replace the thorough constructability review process currently existing in many organizations including WSDOT, but the HCIS is another tool to increase awareness of design engineers to constructability concerns.
