The U.S. Army Corps of Engineers faces a dilemma in seeking to automate construction project scheduling with Critical Path Method CPM software systems, because each vendor uses its own proprietary data format. To purchase and learn eaqh system used by various contractors would be expensive and time consuming. Yet specifying a system leaves the Corps open to charges of giving unfair advantage to contractors using that particular system. Requiring contractors to provide hardware, software, and training for any CPM scheduling system differing from the one specified by the Corps can keep a contractor from being able to submit a competitive bid on a smaller project. The U.S. Army Construction Engineering Research Laboratories USACERL has been working on a solution establishing a standard data format that provides a common ground between proprietary systems. This report chronicles the development of this format, named the Standard Data Exchange Format SDEF. Appendix A to this report is a draft of the SDEF specifications. Additionally, this report evaluates how well the following commercially available systems conform to the SDEF AlderGraf AlderGraf Systems, Inc. OpenPlan Welcom Software Technology Corporation PMS-80 Pinnell-Busch, Inc. PPMS 30,000 Version 4.02 Advanced Project Approach, Inc., and Primavera Primavera Systems, Inc.. MM
