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.

IH 35 at Ronald Reagan Boulevard Bridge

IH 35 at Ronald Reagan Boulevard Bridge Williamson County, Texas The project included schematic development and plans, specifications, and estimates for realigning Ronald Reagan Boulevard into a divided roadway with two one-way alignments. It included the removal of the existing two-way bridge over IH 35 and the construction of two new one-way bridges over IH 35, while continuing to provide connectivity to CR 247 and CR 311. Ronald Reagan Boulevard improvements started 2,300 feet west of IH 35 and proceeded east to IH 35, and continued east for 500 feet. Beginning at CR 247, the new Ronald Reagan Boulevard tapers to a divided roadway (two lanes in each direction), with one-way eastbound and westbound alignments and paved shoulders. In the future, Ronald Reagan Boulevard will be widened to four lanes from SH 195 to CR 247, providing a major artery from Georgetown to IH 35. The project included new safety lighting, retaining walls on IH 35 for the new bridge abutments, construction of auxiliary lanes on IH 35 under the new bridges, and drainage improvements along Ronald Reagan Boulevard, the frontage roads, and IH 35 mainlanes. The offset distance between the east- and westbound alignments of Ronald Reagan Boulevard also provided an adequate span for future freeway construction and additional widening of the boulevard. Public involvement, utility coordination, private land and business owners, the City of Jarrell, emergency service providers, TxDOT, Williamson County, the Federal Highway Administration, the Texas Commission on Environmental Quality, and other stakeholders were important to project success.

Beltway 8 High-Mast Illumination

Beltway 8 High-Mast Illumination Harris County, Texas DCCM provided surveying services for a high-mast illumination design project along Beltway 8 for the Harris County Toll Road Authority (HCTRA) from November 2018 through September 2019. For this project, Baseline coordinated a low-altitude aerial lidar flight along 25 miles of Beltway 8, from north of Lansdale Drive to east of IH 45. This 25-mile segment was divided among four survey consultants, and our firm was responsible for 5 miles from north of Lansdale Drive to Briar Forest Drive. DCCM verified the existing horizontal and vertical controls and established new controls, including primary and secondary aerial controls. Our subconsultant, DAS, used this control for the aerial lidar flight, and DCCM field crews used it to acquire supplemental survey data. GPS set control, and digital differential levels were run through all control points to ensure vertical accuracy. Control index sheets were also provided. Close coordination with DAS and the other three survey consultants was maintained to ensure a seamless and consistent product was delivered. DCCM played a vital role in cost savings for HCTRA by suggesting a single flight for the entire project rather than each consultant acquiring their own flight data. Coordination among the consultants was also ongoing to ensure the survey and aerial control were accurate and relevant. Additionally, DCCM provided supplemental field surveying to map surface features, obscured areas, flowline elevations, pipe sizes, and flow directions for storm drainage, as well as to capture all other features and utilities not captured by the aerial lidar. A Texas811 (one-call) was initiated to have utilities marked and flagged; abstracting and research were performed to obtain the latest ownerships of adjoining parcels; ROW boundaries were determined based on provided record maps, found monumentation, and deeds; and plats were obtained through research for DCCM’s entire segment. DCCM staked the project, and weekly progress reports were provided to the HCTRA Project Manager, enabling our team to execute work in a professional and timely manner.

Piper Road Drainage Improvements

Piper Road Drainage Improvements Brazoria County and Pearland, Texas DCCM provided design plans and specifications for a bid-ready submittal package that included comprehensive drainage and minor roadway improvements for Piper Road. The 2,900-foot project extended from FM 518 (Broadway Street) on the north to Fite Road on the south. The project included an asphalt overlay, along with subgrade repairs where necessary, based on visual cracking and pavement failure. The design reduced the watershed area for the portion of Piper Road draining to the north, which diminished a recurring ponding problem at FM 518. The majority of the roadway now drains to Fite Road on the south using storm sewers underneath the former ditches. Driveway culverts were eliminated for the storm sewers draining to the south and were replaced with area drains between the driveways for direct drainage into the new storm sewer system. Using storm sewers in this manner eliminated the need to do costly utility relocations or ROW acquisition. At about the same cost as acquiring ROW and moving utilities, this concept greatly reduced the time required for project completion and the need to disrupt the front yards of homes along Piper Road. Existing, significant trees also did not need to be removed. Existing water and sanitary sewer main lines and services were either protected or replaced to accommodate the new storm sewers. We leveraged our relationship with CenterPoint Energy to expedite relocations with the proposed storm sewer before construction began, keeping the project on schedule. The project significantly improved drainage compared to the existing roadway ditches. At a Glance 2,900 Feet $1.2 million Construction Cost Markets Municipal Services Water & wastewater

Bayland Island Development

Bayland Island Development Baytown, Texas DCCM provided the surveying associated with the development of this 27-acre peninsula (island) located south of SH 146, just east of the Fred Hartman Bridge in the City of Baytown. Close coordination was conducted with the City of Baytown officials, title companies, and developers. The survey included detailed abstracting of a chain of title for mineral leases, pipelines, and real property records. The firm performed shoreline boundary surveys of tidally influenced areas, boundary surveys of upland areas, and topographic surveys of the island. Additionally, DCCM prepared an American Land Title Association/National Society for Professional Surveyors survey of the island and roadway access from SH 146, as well as a 6.8-acre portion of the island for development. The firm also coordinated utility and access easements and prepared and coordinated the platting of the entire project. An existing marina sports bar and grill facility is located on the island. Locating and identifying existing utility easements and utilities that served the island was difficult, especially a non-visible sanitary sewer force main. The DCCM office personnel and field crew worked closely with the City of Baytown’s public works department, subsurface utility engineering consultants, and others to excavate and locate the buried utility in various places and obtain an accurate location and depth of the line. Another challenge faced during the project was coordinating with engineers, architects, city planners, and various city departments. DCCM implemented a solution by conducting regularly scheduled team progress and scheduling meetings. These meetings were crucial in ensuring the project remained on track and continued progressing productively. Additionally, weekly progress reports were provided to the City of Baytown to inform them about the project’s status. Through this experience, it was learned that regular meetings with the entire team not only help prevent potential issues but also promote organization and accelerate the project’s overall progress.

Cedar Bayou Crossing Corridor Study

Cedar Bayou Crossing Corridor Study Harris County and Baytown, Texas DCCM was selected to provide professional services for the proposed Cedar Bayou crossing. The crossing will serve as a critical link for the City of Baytown to ensure the orderly development of the northern part of the city and provide necessary east-to-west mobility to supplement IH 10. The project area was from Hunt Road at Main Street to Kilgore Parkway at SH 146. DCCM provided project management, data collection, existing condition evaluation, alternative analysis, community outreach support, preliminary engineering, geotechnical investigation, subsurface utility engineering, survey, and an environmental analysis. DCCM conducted a corridor study to identify alignment alternatives and assess the project’s feasibility. The study included several aspects to consider and required sufficient information to measure and evaluate a range of viable improvement options. The traffic analysis reviewed traffic and crash data, existing roadways, traffic flow patterns, traffic counts, turning movement counts, and transit and traffic operations. The DCCM team conducted capacity analyses for designated locations and sections of roadways and made recommendations to improve traffic flow. DCCM provided hydrology and hydraulics to support the corridor layout of the proposed roadway. This task used the latest Mapping, Assessment, and Awareness project (MAAPNext) models for Cedar Bayou as developed by the Harris County Flood Control District. DCCM also provided community outreach, public meetings, and City Council meetings. The project concluded with identifying recommended improvements, preliminary plans with several alternatives and their estimated costs, and a preferred alignment. Surveying Services DCCM performed professional surveying services to obtain and review existing lidar data and the limited preliminary ground survey data for the Cedar Bayou Corridor Study. The project spanned 3.7 miles from North Main Street, 3,300 feet south of IH 10 (west tie-in point), to the intersection of SH 146 and Kilgore Parkway (east tie-in point). The latest available lidar data published from USACE and Texas Natural Resources Information System covering the project area to evaluate and perform the following tasks: Data sets were extracted/downloaded into Esri ArcGIS (Pro+3D Analyst tool) and Context Capture/OpenRoads Cross-data checks were performed against public datasets from TxDOT, the City of Baytown, Harris County, and other available online resources. The MicroStation DGN deliverable included: DEM 2D building/structure footprints Roads, highways, and railroads Overhead transmission lines Other visible features within the lidar data Limited field surveying was performed.
