FM 1097 Widening, Segments 1, 2, 3

FM 1097 Reconstruction, Segments 1, 2, and 3 Montgomery County/TxDOT | Montgomery County, Texas This project was a joint effort between Montgomery County and TxDOT and involved widening an existing two-lane with a dedicated left-turn lane road into a four-lane with a dedicated left turn. Binkley & Barfield | DCCM was responsible for the identification of utilities, design coordination, permit and utility agreement review, and relocation oversight. Utility adjustments were needed for all utilities due to most right-of-way (ROW) being taken on one side. Binkley & Barfield | DCCM worked closely with ROW to prioritize parcel acquisitions so utilities could complete adjustments without delays. Utilities included Entergy, Kinder Morgan pipeline, CenterPoint Energy, numerous telecommunications lines, and City of Willis water and wastewater. Binkley & Barfield | DCCM worked with the design team to mitigate any utility conflicts that could be costly or would require a long lead time for adjustments. Binkley & Barfield | DCCM set up several utility workshops between the roadway design team, the utility owner, and the construction area office to work through the details to allow a pipeline to be protected in place and avoid a costly relocation. Other coordination efforts included working with the design team on the traffic control phasing to allow the utilities more time for adjustments while allowing the roadway contractor to continue working without delays.

FM 646 Reconstruction

FM 646 Reconstruction Galveston County/TxDOT | Santa Fe, Texas Binkley & Barfield | DCCM provided engineering and construction management services to reconstruct and upgrade existing FM 646 from FM 1764 to SH 6 for Galveston County and the TxDOT in Santa Fe. The project included widening FM 646 from an existing two-lane asphalt roadway with open roadside ditches to a proposed four-lane concrete roadway with two-way left-turn lanes and storm sewer. The project also involved grading, lime-treated subgrade, Portland cement-treated base, bond breaker, continuously reinforced concrete pavement, inlets and storm sewer, outfall channel, drainage structures, signing, pavement markings, traffic signals, traffic control plan, and a stormwater pollution prevention plan. The roadway improvements required purchasing an additional 20 feet of right-of-way. This project also included a realignment of the roadway so that TxDOT design criteria were met, allowing a new 150-foot prestressed slab beam bridge to be constructed over Highlands Bayou. Binkley & Barfield | DCCM refined the roadway profile to not only meet the TxDOT design criteria but also to minimize the need for construction easements during construction, which ultimately reduced the overall cost of the project. The bridge design included four lanes, a raised sidewalk, and a combination rail on the outside. The bridge foundation design was performed using the Client Assistance 18 program. The realignment also required that Binkley & Barfield | DCCM retain a portion of the existing roadway in place to maintain access to city streets and businesses. Signal design included modification to the signal at the FM 1764 intersection and modification to the signals at 6th Street and SH 6. The signal at SH 6 required coordination with Union Pacific Railroad due to its proximity to their railroad crossing, which ensured that all railroad crossing preemption measures would remain functional. Binkley & Barfield | DCCM also provided construction management services, utility coordination, and relocation for several utility companies, including AT&T, Comcast, CenterPoint Energy gas, and Phonoscope. We delivered weekly utility relocation updates for the contractor and TxDOT to facilitate and adhere to the project construction schedule. Our team was also entrusted by TxDOT to review and approve permit applications for proposed relocation for the entire project.
