Authorize a construction contract for the White Rock Lake Dam and Spillway Maintenance Improvements Project - Rebcon, Inc., only bidder - Not to exceed $5,997,105.00 - Financing: Water Capital Improvement E Fund
Body
BACKGROUND
The White Rock Lake Dam and Spillway was originally constructed in 1911 and today includes an approximately 47-foot tall earthen embankment and 450-foot long concrete overflow spillway. The dam is operated and maintained by the Dallas Water Utilities (DWU) Department and is regulated by the Texas Commission on Environmental Quality. As part of regulatory requirements, DWU performs monthly, annual, and five-year regulatory inspections to assess the condition of the dam and recommend maintenance repairs, additional monitoring measures, operational improvements, or risk mitigation strategies. In December 2016, a White Rock Dam Safety Inspection Report was completed that recommended several maintenance repairs to improve the condition of the dam and protect the critical infrastructure asset.
In the interest of public safety and compliance with local, state, and federal dam and environmental regulations, DWU has prepared construction plans and specifications to address recommended maintenance repairs from inspections of the White Rock Dam and Spillway. This action will authorize a construction contract to perform the recommended maintenance of the dam and spillway, including structural concrete repair to the stop log channels and spillway slabs, replacement of broken concrete on the waterside face of the earthen embankment, slope protection on the land side of the earthen embankment to control erosion, and vegetation removal at the base of the dam to allow for maintenance access and inspection and to prevent invasive roots from impacting the integrity of the dam. In addition, grout injection, concrete joint sealant replacement, and painting of the parapet wall along the top of the dam are included in the proposed improvements.
