Brays Bayou Federal Flood Control, Multiple Channel Improvements, and Bridge Replacements

Harris County Flood Control District | Houston, Texas

Binkley & Barfield | DCCM was contracted by HCFCD to provide engineering services for three separate projects for Brays Bayou.

Channel Modifications, Discrete Segment 109 – Binkley & Barfield | DCCM evaluated the impact of the proposed channel widening to the existing foundation of eight bridges. Binkley & Barfield | DCCM also designed the soil nail and gravity retaining walls to protect the bridge abutments and stabilized the bayou banks. Additional services included preparing a structural analysis of the proposed walls per Harris County Flood Control District criteria, plans, specifications, and estimates, force mains relocation design, relocation and replacement of existing storm sewer flap gate boxes, and an updated evaluation of the previous IH 610 bridge engineering report. Services also included an alternative final design, evaluation of existing bridge foundations capacity, and a recommendation on soil excavation impact. Construction cost: $11 million

Telephone Road, Lawndale Street, South 75th Street, and Almeda Road Bridge Replacements – Binkley & Barfield | DCCM provided preliminary and final design and bid and construction phase services for the replacement of the four bridges. Binkley & Barfield | DCCM investigated the site, researched record drawings and existing utilities, and performed a topographic survey of the existing channel and bridges to supplement data. Binkley & Barfield | DCCM assisted with the coordination for lane configurations and sidewalk width to determine typical bridge sections and prepared exhibits showing alternatives for each bridge. Binkley & Barfield | DCCM prepared traffic control plans, local drainage design, stormwater pollution prevention plan, a drainage area map, hydraulic calculations, and drainage standards. Construction cost: $23 million

Stella Link Road and Ardmore Street Bridge Replacements – Binkley & Barfield | DCCM provided the design, coordination, scheduling, and plans, specifications, and estimates for the replacement of the existing Ardmore Street bridge and addition of a new span to the Stella Link Road bridge. The project increased the hydraulic capacity of Brays Bayou by expanding the cross-sectional area under the bridges. The new bridge at Ardmore Street provided a U-turn, wider lanes, and sidewalks for community connectivity. The project included a compressed schedule to meet federal funding requirements, environmental issues, and utility.
