Huitt-Zollars prepared construction documents for the rehabilitation of the outlet structures for the Addicks and Barker Reservoirs in Houston, Texas. These “extremely high-risk” dams provide flood-damage reduction for our nation’s fourth largest population center. The project included replacement of non-functional Gate #1 at Barker Reservoir; installation of new on-site standby diesel generators at each site to operate the gates during utility outage conditions, including new buildings to house the generators, transfer switches, associated equipment and the installation of new electrical service conduit and wiring; additional lighting at the inlet and outlet structures to enhance security at the dams and facilitate maintenance operations.; replacement of existing fiberglass walkway grating on the service bridges and intake structures with galvanized steel grating; and painting of the gates and support structures. Huitt-Zollars also prepared evaluation reports for the mechanical and electrical components of the floodgates and operators along with a Design Document Report and an MII cost estimate. Huitt-Zollars also reviewed submittals and shop drawings during construction.
