2020 Multi-Street Reconstruction

2020 Multi-Street Reconstruction Pasadena, Texas DCCM provided preliminary and 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 (ADA)-compliant sidewalks/shared-use paths and ramps, signing and pavement markings, traffic control, a stormwater pollution prevention plan (SWPPP), a complete drainage study, and a geotechnical report. This reconstruction project was bid on a unit-price basis before design began and executed on a fast-track schedule. This included close coordination between 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 the necessary detention within the street’s limits. This fast-track process will set the path for future projects designed and constructed within the City of Pasadena. The design and reconstruction of all streets were completed within an accelerated 12-month schedule.

42-inch Water Line Design, Segment 3 A1

42-inch Water Line Design, Segment 3 A1 Harris County, Texas DCCM provided final design and construction phase services for 14,000 linear feet of 42-inch water transmission line within a CenterPoint Energy electric transmission line corridor and easement. This water line is part of the West Harris County Regional Water Authority’s (WHCRWA) 2025 system, which will meet at least 60% of water demand with surface water. This is the latest project in a long history of working with WHCRWA to supply their surface water requirements. The project involved installing water lines in CenterPoint Energy’s electrical transmission line corridor for miles. Trenchless construction was required within 20 feet of truss towers and across busy roadways. Close coordination was maintained with the City of Houston and Harris County for permitting and the acquisition of record drawings. 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.

FM 1097 Widening, Segments 1, 2, 3

FM 1097 Widening, Segments 1, 2, and 3 Montgomery County, Texas This project was a joint effort between Montgomery County and TxDOT. It involved widening an existing two-lane road with a dedicated left-turn lane into a four-lane road with a dedicated left-turn lane. DCCM was responsible for identifying utilities, coordinating design, reviewing permits and utility agreements, and overseeing relocation. Utility adjustments were needed for all utilities due to most right-of-way being taken on one side, and DCCM worked closely with right-of-way to prioritize parcel acquisitions so utilities could complete adjustments without delays. Utilities included Entergy, Kinder Morgan pipeline, CenterPoint Energy, numerous telecommunication lines, and the City of Willis water and wastewater. DCCM worked with the design team to mitigate utility conflicts that could be costly or require long lead times for adjustments. Our team set up several utility workshops among the roadway design team, the utility owner, and the construction area office to work through the details to protect the pipeline in place and avoid a costly relocation. Other coordination efforts included working with the design team on traffic control phasing to give utilities more time for adjustments while allowing the roadway contractor to continue working without delay.

Avenue S Rehabilitation

Avenue S Rehabilitation Galveston County DCCM provided the design of 8,600 linear feet of roadway reconstruction along Avenue S from 53rd Street to Seawall Boulevard. The paving cross-section comprised two travel lanes with two outside parking areas. The project design included replacing 8,900 linear feet of water line, including branches and intersections along the route, crossing intersections that were previously reconstructed for other concurrent projects. Additionally, a 15-inch sanitary sewer was replaced, stretching from 35th Street to 33rd Street, including branches and intersections. Our assessment of the drainage system along the corridor and side streets enabled us to determine the most effective methods for enhancing drainage efficiency while removing bridge blocks. The flat terrain of Galveston provided grading challenges, and with our detailed 3D grading abilities, the shallow underground storm system had the proper cover under the road and for some instances where standard cover was not achievable, it was discovered and known during the design or it was identified during construction and the design remedies were ready before construction was delayed. Our subconsultants performed geotechnical, surveying, SUE, environmental, and inspection services for the project. DCCM provided construction phase services for the City of Galveston and collaborated with the contractor to ensure the design intent was effectively implemented. The final product of the road was excellent, and the contractor successfully constructed the road and storm sewer system with minimal RFIs and minor adjustments to the road, sidewalks, and storm sewer system grading. All meetings were accompanied by a well-organized agenda and meeting minutes, which included detailed action items to be completed by the next meeting. This attention to detail and accountability helped lead the project to a successful completion and limited citizen complaints. Surveying Services DCCM supported land surveying services for 2.5 miles of Avenue S from 53rd Street east to Seawall Boulevard Drive. Tasks included right-of-way (ROW) determinations, topographic surveying, and subsurface utility surveying to support engineering design. The project included a full-depth replacement of existing pavement and utilities, including water lines and subsurface sanitary and storm sewer systems. Approximately 275 parcels were abstracted to support ROW determinations and graphically depict property ownership. Survey control was established, including ground targets for aerial triangulation of UAS/drone imagery acquired by a subconsultant. Lidar data was also collected, post-processed, and delivered to us for analysis and integration into our survey. Supplemental ground surveying was performed to support the validation of the imagery and lidar data. Final deliverables included 3D mapping in Civil 3D format and rectified orthomosaic imagery of the project extents. SUE Services DCCM provided SUE services along 8,600 linear feet of water and sanitary sewer line from Avenue S from 53rd Street to Seawall Boulevard. The SUE QL-B designation revealed more than 56,000 feet of utilities in that area. As in all SUE projects, the utility mainlines were designated. This project was unusual because all utility services were also designated so that the designers would have substantial utility information and the best chance to protect the utilities in place—this required electronically traceable duct runners, fish tapes, and electromagnetic sweeping.
