Description/History
Project No. 28 in the 2019 Water Master Plan is the Capital Improvements project to expand the Bud Ervin Water Treatment Plant (BEWTP) from 45 million gallons per day (MGD) to 60 MGD capacity production of potable water. This project is funded primarily through a $50,000,000 bond issuance.
Resolution 3972-23 and Resolution 3973-23 issued January 23, 2023 authorizes the contract to Plummer and Associates, Inc. for the design of the BEWTP Phase V Expansion from 45 MGD to 60 MGD and authorizes the Construction Manager-at-Rick (CMAR) delivery method. Resolution 4106-23 issued on October 23, 2023 approves the award of the CMAR contract to Archer Western Construction, LLC.
Archer Western Construction, LLC. solicited proposals, defined as Bid Package 1, from Aria Filtra (Pall) and H2O Innovations/Nanostone to provide costs and scope of supply of equipment. Bid Package 1 proposals were received, opened, and read aloud in a public forum on August 2, 2024.
The proposals from Bid Package 1 have been evaluated by Plummer and Associates, Inc. in coordination with Archer Wester Construction, LLC. and City of Mansfield’s Engineering Services and Public Works Departments. Plummer and Associates, Inc. provided a recommendation to award the proposal submitted by Aria Filtra (Pall) on August 23, 2024 defined by Bid Item A.3 to provide the full buildout membrane production capacity to 33.41 MGD. This selection will increase the BEWTP production capacity from 45 MGD to 63 MGD, which is 3 MGD additional production capacity above the expected Master Planned anticipated capacity limit of 60 MGD.
This Work Authorization directs Archer Western, LLC. to select Aria Filtra’s Bid Item A.3 proposal from the Bid Package 1 evaluation and selection. The requested funds of $7,281,338.00 include equipment to be supplied at $6,470,000.00, the contractually obligated CMAR Fee of $517,600,000.00 at 8%, the contractually obligated bonds and insurance costs of $99,638.00 at 1.54%, and a CMAR Contingency Allowance of $194,100.00.
Justification
This early-out package has a long lead time (up to 54 weeks) and must be selected early to allow engineering design to move forward, as this is the largest component of the project. The total cost for Work Authorization 1 is within budget for the overall project and will be rolled into the final Guaranteed Maximum Price (GMP) when design is complete. Engineering Services and Public Utilities staff recommends Work Authorization 1 award to Archer Western Construction, LLC.
The Executive Director of Public Works will attend the meeting to answer Council’s questions.
Funding Source
The funding source will be from the Utility Construction Fund.
