Roadway

Cedarspur Drive, Burkhart Road, and Winningham Lane Improvements Spring Valley Village, Texas DCCM provided the preliminary engineering report, design, survey, and SUE QL-C and D for road paving and utility improvements in three separate areas of the City of Spring Valley Village. The project encompassed the reconstruction of Cedarspur Drive, Burkhart Road, and Winningham Lane East, totaling 2,200 linear feet. It included replacing 6,400 square yards of concrete roadway and driveways, water line, and sanitary improvements. Additional services included attending pre-bid meetings, bid evaluation, and award recommendation. DCCM also attended a preconstruction conference, reviewed shop drawings and requests for information, performed site visits as specified by the client, and provided record drawings. The design of the TCP was challenging because the project consisted of three streets with dead ends, requiring us to maintain two-way traffic while rebuilding a two-lane roadway. We limited work zones to 400 linear feet at a time to make it easier for residents traveling to and from their homes. Ongoing flagging and coordination with residents was imperative for a smooth project. DCCM coordinated closely with the City of Spring Valley Village, the contractor, and affected homeowners to provide a seamless design and construction experience. Homeowners were notified of the schedules, including the start and end times for work on their street. Homeowners were also encouraged to notify the city, the contractor, or the engineer if there were any issues. The project went smoothly with minimal issues.

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.

Avenue S Rehabilitation Galveston County, Texas 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.
