Abstract
Construction Standard Productivity Manual Unit system(CSPM) has been used for estimating the contract amount of construction projects in public sector. CSPM has been annually either revised and/or updated with high socio-economic cost. This study identifies simulation modeling and analysis is an effective tool to complement the issues involved in revising, updating, and enacting CSPM. This paper presents how Web-CYCLONE which is a discrete event simulation systems can be effectively used for this purpose. This study verifies that the enhanced simulation system can effectively assist enacting and/or revising CSPM using a new version of Web-CYCLONE that implements new modules specialized to CSPM revision. A test case with gas pressure welding operation is performed to verify the usability of the add-in modules.
