SUBJECT
Title
Authorize an increase in the construction services contract with Archer Western Construction, LLC, for additional work associated with Dallas Water Utilities’ raw water system facilities located at Lake Ray Hubbard - Not to exceed $993,520.00, from $32,082,400.00 to $33,075,920.00 - Financing: Water Construction Fund
Body
BACKGROUND
Dallas Water Utilities (DWU) identified and evaluated 10 raw water facilities based on their age and condition, impact to the system, reliability, cost to operate, and frequency of repairs. The most critical raw water facilities were found to include the lake intake, Forney Pump Station, and Forney Dam at Lake Ray Hubbard. Lake Ray Hubbard is the only DWU reservoir owned and operated by the City of Dallas. The reservoir and associated water supply infrastructure were constructed in the late 1960’s and early 1970’s and several critical components require rehabilitation and replacement.
On August 10, 2022, the City Council authorized a construction services contract with Archer Western Construction, LLC for major rehabilitation and replacement of infrastructure at Lake Ray Hubbard. Improvements include traveling screens, sluice gate replacement at the intake, pump and valve replacement, site civil and groundwater monitoring improvements, monorail and bridge crane system improvements, new stop logs and storage building, spillway concrete repairs, spillway gate repairs, heating, ventilation, and air conditioning upgrades, and electrical and control improvements for the Forney Dam. The existing facilities have reached the end of their useful life, have limited operability, and are difficult to access and repair.
This action will authorize Change Order No.1 to the construction services contract with Archer Western Construction, LLC for additional work associated with the rehabilitation and replacement of infrastructure at Lake Ray Hubbard. During construction, additional work not within the original contract was identified and is required to complete the proposed improvements. The additional work includes repair of the tainter gates and inspection of the low flow West slide gates, services for the crane rail design, replacement of one 60-inch butterfly valve, meter flow vault, replacement of two pressure relief/pressure sustaining surge control valves, and installation of new doors and hardware at the Forney Pump Station electrical building and bulkhead storage building.
