Cedarspur Drive, Burkhart Road, and Winningham Lane Improvements

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.

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

108-Inch Northeast Transmission Line, Contract 99D-2 Houston, Texas DCCM provided final engineering design and construction-phase services for 1.4 miles of 108-inch water main from Aldine Westfield Road to Willis Street in north Houston. This project was extremely complex due to the size of the water main and the congested area where the alignment was located. DCCM worked with the City of Houston and its Program Manager to develop a 50-foot water line easement through an existing urban region. To develop the preferred alignment, DCCM considered construction issues, including laydown areas, environmental constraints, traffic impacts, and existing utilities. DCCM developed alignment alternatives, such as tunnels instead of open-cut construction, in multiple areas to minimize or eliminate significant impacts on existing businesses, as numerous commercial buildings are close to the route. Tunnels were designed to mitigate the impact on the buildings and their operations in these areas. Since the project was in an urban region, 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. Each method was optimized for the project.
