SUBJECT: Accept Work for Early Work Package No. 1 for Northeast Water Purification Plant Expansion Project.
RECOMMENDATION: Pass a motion to approve the final Contract Amount of $36,698,489.00 or 1.72% under the Original Contract Amount of $37,339,549.00, accept the Work and authorize final payment.
SPECIFIC EXPLANATION: The project was part of the Northeast Water Purification Plant Expansion early construction work to meet the project milestones. This package consisted of the site development of approximately 90 acres and was subdivided into seven (7) subcontract packages: Survey, Temporary Construction Fencing, Erosion Control, Clearing and Grubbing, Earthwork, Utility Relocations, and Temporary Power and Lighting. The project was awarded to Houston Waterworks Team (a joint venture between CH2M Hill Engineers, Inc. and CDM Constructors Inc.) designed with three hundred and fifteen (315) days for construction and an original contract amount of $37,339,594.00.
This project was described and briefed to the Transportation, Technology, and Infrastructure (TTI) Committee on August 6, 2020.
LOCATION: This project is located at 12630 Water Works Way, in Humble.
Contract Completion and Cost: The Contractor, Houston Waterworks Team, has completed the work under the subject Contract. This Amendment’s schedule was subsumed within the Amended and Restated Design Build Agreement between the City and the Contractor. The final cost of the project, including overrun and underrun of estimated unit price quantities and previously approved Change Order Nos. 1 - 5 is $36,698,489.00, a decrease of $641,105.00 (1.72%) under the Original Contract Amount. The decreased cost is a result of the difference between planned and measured quantities and unspent escalation.
M/WSBE Participation: The advertised M/WSBE contract goal for this project was 80.45%. The final achieved participation was 79.56% and was reviewed by the Office of Business Opportunity (OBO). Typically, when a project closes, a M/WSBE performance rating is assigned. However, this closeout represents only a fraction of many contract packages to be completed for the Northeast Water Purification Plant Expansion, a performance rating from OBO was not offered at this time.
