MWDBE PARTICIPATION: The advertised M/WBE contract goals for this project were 12.94% MBE and 8.72% WBE (21.66% total). The M/WBE goals approved for this project were 12.94% MBE and 8.72% WBE (21.66% total). According to the Office of Business Opportunity, the actual participation achieved on this project was 13.06% MBE and 0.56% WBE (13.62% total). The standard for meeting MWBE participation goals is the demonstration of Good Faith Efforts. The Contractor’s M/WBE performance on this project was rated Satisfactory due to Good Faith Efforts for the following reasons: due to significant changes to the project, the work orders were comprised mostly of specialized technology work that could only be self-performed by the prime. Additionally, change orders eliminated the services slated to be provided by some goal credit subcontractors on the project. In one instance, change orders applied to the project because of emergency repairs to a 72-inch waterline caused major cost overruns that eliminated a substantial portion of the funding for this project. For the reasons listed, the Contractor's performance meets the intent and spirit of the City of Houston's MWBE program.
