Title

Authorize Supplemental Agreement No. 4 to the professional services contract with Arcadis CE, Inc. f/k/a Malcolm Pirnie, Inc. to provide additional engineering services associated with water quality improvements at the Elm Fork Water Treatment Plant - Not to exceed $2,371,053.00, from $25,908,306.00 to $28,279,359.00 - Financing: Water Capital Improvement G Fund

 

Body

BACKGROUND

 

In June 2006, Dallas Water Utilities (DWU) initiated a study to investigate the cause of water quality concerns in parts of the water distribution system. The study and requisite testing confirmed that the treated water chemically changes as it moves through the water system. Recommendations to stabilize the water included process changes and the implementation of improvements at all three water treatment plants. Three firms, one firm for each water treatment plant, were selected to perform engineering and design services. It was anticipated that each firm would be awarded planned supplemental agreements as work progresses to ensure a targeted approach to design.

 

One major recommendation from the 2006 study included the implementation of biologically active filtration at each plant. DWU has successfully implemented biologically active filtration at the East Side and Bachman Water Treatment Plants and is working to implement these improvements at the Elm Fork Water Treatment Plant. The next step includes the construction of a new Filter Complex to convert treatment operations, address hydraulic limitations, and upgrade existing infrastructure at the end of its useful life. The Elm Fork Water Treatment Plant located in Carrollton, Texas, is the second largest of the three water treatment plants serving DWU customers. It was constructed in the 1950s, underwent an expansion and renovation to its current capacity of 300 million gallons per day in the early 1990s, and is now in need of water quality improvements to continue providing reliable service and producing high-quality water to customers.

 

 

 

 

On July 9, 2021, two bids were received for the Elm Fork Filter Complex project. After reviewing bids, it was determined that they were significantly higher than the engineer’s estimate and the available project budget. The high costs were found to be influenced by current shortages in labor and materials, limited contractor competition in the North Texas market for the scope and scale of the project, and the risks associated with pricing volatility of raw materials given the multi-year project schedule. DWU rejected the bids and is working with the engineer to repackage the project into phases to receive more bids and better prices. The first phase is scheduled to be advertised for construction bids in May 2022.

 

This Supplemental Agreement No. 4 continues to advance the goals of the Water Quality Improvements Program at the Elm Fork Water Treatment Plant by providing engineering design and bid phase services for the new Filter Complex Package #1. Services include splitting and repackaging the Filter Complex design into smaller, more easily funded projects, evaluating alternate delivery and funding options for the remaining project phases and water quality improvements, bid phase services for Package #1, engineering support for the evaluation and management of existing infrastructure until the project is completed, continued construction administration support through the completion of the ongoing Pump Station 1 replacement project, preparing a drainage plan for the site, and special services to prepare for new regulatory requirements. Future supplemental agreements will be required for construction administration and start-up of the Filter Complex Package #1, the design and construction of subsequent Filter Complex packages, and future improvements to complete the overall Water Quality Program at the Elm Fork Water Treatment Plant.
