Emergency Repairs to White Oak Bayou After Hurricane Ike

Huitt-Zollars conducted a site survey and prepared construction drawings, specifications and cost estimates to repair approximately four hundred fifty (450’) feet of channel embankment on White Oak Bayou that had been damaged during Hurricane Ike.  Huitt-Zollars performed a topographic survey to document the existing conditions, identify the repair area, and provide a baseline condition for estimating project unit quantities for bidding and constructing the repair work.  Huitt-Zollars prepared construction drawings and specifications for the repair of damaged area and made design submittals at the 65%, 90%, and 100% design milestones.  The drawings and specifications identified the project area as well as concrete scour pad plan sections and details required for the repair. A MII cost estimate was prepared and submitted at the 90% and 100% submittals. The drawings, specifications and cost estimate were prepared in accordance with applicable USACE Technical Manuals, Criteria and Standards. Huitt-Zollars prepared a Design Documentation Report in accordance with ER 1110-2-1150 for the 90% and 100% submittals.  Based on engineering calculations by Huitt-Zollars, the weep holes and sand filter bedding identified in the PIR were determined to be unnecessary which significantly reduced the cost of the construction.  Huitt-Zollars participated in Technical Reviews; an Over-the-Shoulder Review and a Biddability, Constructability, Operability, and Environmental (BCOE) Review with members of the District’s Project Team.  The project was completed ahead of schedule. Estimated construction cost: $105,491.
