DESCRIPTION/SCOPE: The project consisted of relocation, reconditioning, refurbishing, testing, and complete installation of Waukesha VHP5900GSi gas enginator generating system from Southwest Wastewater Treatment Plant (WWTP) to Northwest Wastewater Treatment Plant (WWTP). Chiang, Patel & Yerby, Inc. designed the project with 180 calendar days. The project was awarded to C. F. McDonald Electric, Inc. with an original Contract Amount of $834,469.00.
LOCATION: The project area is located at 5423 Mangum, Houston Texas, Key Map Grid 451C.
CONTRACT COMPLETION AND COST: The Contractor, C.F. McDonald Electric, Inc. has completed the work under the subject Contract. The project was completed on time with additional 888 days approved by Change Order Nos. 1 and 2. The final cost of the project, including overrun and underrun of estimated unit price quantities and previously approved Change Order No. 1 is $843,879.03, an increase of $9,410.03 or 1.13% over the original Contract Amount and under 5% contingency amount.
The increased cost is a result of the difference between planned and measured quantities. This increase is primarily the result of an overrun in various Base Unit Price Items and Extra Unit Price Items, which was necessary to complete the project.
MWBE/SBE PARTICIPATION: No City MWSBE participation goal was established for this project, as the contract will not be a goal oriented contract per Section 15-82 of the Code of Ordinances.
