Inter-Agency Infrastructure Coordination and Assessment Tool

Inter-Agency Infrastructure Coordination and Assessment Tool Harris County | Harris County, Texas Binkley & Barfield | DCCM was selected as the prime firm for assembling an Inter-agency Infrastructure Coordination and Assessment Tool. The purpose of the tool was to assist Harris County and partner agencies with project statuses and updates on capital improvement projects across Harris County. Partner agencies include TxDOT, Harris County Flood Control District, METRO, Harris County Toll Road Authority, City of Houston, and the Houston Parks Board. The tool was developed as a GIS using the Environmental Systems Research Institute platform.

42-inch Water Line Design, Segment 3 A1

42-inch Water Line Design, Segment 3 A1 West Harris County Regional Water Authority | Harris County, Texas Binkley & Barfield | DCCM provided final design and construction phase services for 14,000 linear feet of 42-inch water transmission line in a CenterPoint Energy electric transmission line corridor and easement. This water line is part of the West Harris County Regional Water Authority’s 2025 system, which will provide at least 60% of the water demand using surface water. This is the latest project in a long history of working with the Authority to supply their surface water requirements. Challenges The project involved installing water lines in CenterPoint Energy’s electrical transmission line corridor for miles. Trenchless construction was required near truss towers within 20 feet, as well as for crossing busy roadways. Close coordination was maintained with the City of Houston and Harris County for permitting and record drawing acquisition. Collaboration with the design engineer ensured a proper connection to an 84-inch water line. Additionally, coordination with multiple petroleum pipelines and dry utilities in CenterPoint Energy’s corridor was necessary.

108-Inch Northeast Transmission Line, Contract 99D-2

108-Inch Northeast Transmission Line, Contract 99D-2 City of Houston | Houston, Texas Binkley & Barfield | DCCM provided final design and construction phase services for 7,400 linear feet of 108-inch water transmission line from Aldine Westfield Road to Willis Street in City of Houston-owned easements inside the North Sam Houston Parkway. Since the project was in an urban region, Binkley & Barfield | DCCM worked closely with the existing utilities to develop utility conflict documents and support their relocation. The design also included construction phasing and traffic control to maintain access to residences, facilities, and emergency services. The water line was a significant transmission main constructed via open-cut and tunneling methods. This project was part of the City of Houston’s work to meet the Harris Galveston Subsidence District’s 2025 50 percent surface water mandate. It is Binkley & Barfield | DCCM’s latest project in a long history of working on large-diameter water line projects for the City of Houston. Project challenges included the water line design’s complexity because of the pipe’s considerable size and the constraints imposed by the limited easement area. It was important to collaborate closely with the City of Houston and its Program Manager to follow the program design standard, requiring constant communication throughout the project’s duration. In addition, the design phase involved creating multiple tunnels spanning various landscapes, including businesses, parking lots, and existing pipelines, ensuring structural integrity and functionality. We also had to coordinate with a pipeline company about the implementation of a trenchless crossing to navigate their aging infrastructure.

2020 Multi-Street Reconstruction

2020 Multi-Street Reconstruction City of Pasadena | Pasadena, Texas Binkley & Barfield | DCCM provided the preliminary design, final design, bidding, and construction phase services for reconstructing 12,220 linear feet of neighborhood residential streets and a collector street within the City of Pasadena. The project comprised nine separate residential streets, including West Park Lane, Madison Avenue, Austin Avenue, Easthaven Drive, Magnolia Street, Tilden Drive, Polk Avenue, Kansas Street, and Llano Street, a major collector.  The project scope included the complete reconstruction of existing neighborhood concrete roads, including storm sewer, sanitary sewer, and water line replacements and upgrades. The project also included Americans with Disabilities Act-compliant sidewalks/shared-use paths and ramps, signing and pavement markings, traffic control, a stormwater pollution prevention plan, a complete drainage study, and a geotechnical report. This reconstruction project was bid on a unit price basis before the design began and was executed on a fast-track schedule. This included close coordination between Binkley & Barfield | DCCM and the contractor during the design and continuous coordination with the City of Pasadena and the contractor. This close coordination allowed changes to be quickly made in the field during construction as required. Portions of the project required innovative engineering to provide necessary detention within the limits of the street. This fast-track process will set the path for future projects designed and constructed in Pasadena. The design and reconstruction of all streets were completed in an accelerated schedule of 12 months.
