Burkart Boulevard Bypass

Burkart Boulevard Bypass Seymour, IN This project involved constructing a 4.7-mile-long bypass around Seymour. The bypass extends from the US 50/Burkart Boulevard Intersection southwest and connects to the O’Brien Street intersection. The first phase of the project features a 99-ft. long bridge over the Conrail railroad, an MSE wall design that minimized the right-of-way footprint, a single-lane roundabout that can accommodate semi-truck and farm equipment traffic, and a new multi-use pathway along the project limits. The bypass also resulted in entirely new alignment and permanent traffic pattern changes. DCCM participated in extensive public involvement, continually coordinated with INDOT, the City of Seymour, and Conrail Railroad, and provided on-site and off-site mitigation efforts to accommodate all project features.

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.

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. At a Glance 12,220 Linear Feet $11.4 million Construction Cost Services Service Markets Market

US 79 Widening

US 79 Widening Jewett, Texas The DCCM team designed a 10-mile schematic and environmental project in Leon County. The project consisted of widening US 79 from a two-lane section to a four-lane divided section from west of Jewett at FM 1512 to Buffalo. This project developed three alternatives and refined the preferred alternative based on stakeholder input from two public meetings, environmental constraints, and limited right-of-way (ROW). The team worked on developing all environmental technical reports required to obtain environmental clearance for ROW acquisition and utility relocation before the final design. One project challenge involved reintroducing a relief route around the City of Jewett during the 90% schematic design. The DCCM team collaborated with the Emerging Technologies group to devise potential relief routes and create exhibits for the upcoming public meeting. Additionally, the DCCM team generated 3D renderings for downtown design options and collaborated with the City of Jewett to gain consensus from key stakeholders. Another challenge involved two grade-separated railroad crossings with BNSF and UPRR. The UPRR crossing featured a rail siding to the Nucor Corporation plant. To address this, seven alternatives were developed to convert the Nucor Corporation at-grade crossing into a grade-separated crossing, ensuring access to Nucor Corporation plants and CR 347. In coordination with Nucor Corporation and TxDOT, the team worked to find a design solution that accommodated all parties while minimizing interchange construction costs.

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.

SH 288 Bridge Improvements

SH 288 Bridge Improvements Brazoria County, Texas TxDOT awarded a statewide indefinite deliverable contract for bridge engineering to DCCM for bridge engineering services. For work authorization No. 1, DCCM was awarded a project in Brazoria County to prepare plans, specifications, and estimates for bridges at three intersections along SH 288. The project required the design of new overpass structures at the intersections of SH 288 with CR 57 and CR 64, the widening of an existing structure at SH 288 and CR 56, and two frontage-road creek-crossing bridges. The structural designs ranged from TxDOT-standard multi-column TxGirders for stream crossings to green ribbon overpasses with U-beams and inverted tees with skews, to modified details with TxGirders. The designs addressed utility conflicts, wetland and stream impacts, skewing, and embankment settlement mitigation. We provided bridge layout plan sheets for each bridge and a comparative cost analysis. The team set bridge spans and limits to achieve optimal beam design and vertical clearance. CR 57 Constructed new location CR 57 cross-street bridge (DCCM) Added ramps Added auxiliary lanes Constructed two frontage road bridges CR 64 Constructed new location CR 64 cross-street bridge (DCCM) Added ramps Added auxiliary lanes CR 56 Widened the existing CR 56 bridge (another consultant) Added frontage roads Added auxiliary lanes Design aspects of the project included surveying, geotechnical engineering, bridge design, roadway design, drainage, environmental engineering, and subsurface utility engineering. As the prime provider of the project, DCCM held an e-mail version of the design concept conference before the 30% submittal. The project milestones were 30%, 60%, 90%, 95%, 100%, and the final milestone. DCCM’s engineers coordinated closely with the adjacent segment engineers to assure continuity of design across segment lines. DCCM presented several typical section options to TxDOT prior to beginning the design to ensure TxDOT’s needs were prioritized. The chosen roadway section included a 16-foot median, four 12-foot lanes, two 12-foot shoulders, and a 5-foot, 6-inch sidewalk with C223 rail. The overall roadway width is 103 feet. The project included converting two-way frontage roads to one-way operations. The team used Atlas 14 to determine the floodplain width for the frontage road bridges over West Fork Chocolate Bayou at CR 5. At a Glance $57.2 million Project Cost Services Service Markets Market

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.

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 (H&H) 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. Field surveying tasks included setting four project control points, performing limited topographic surveying along North Main Street (1,000 feet north and south of the west tie-in point) and SH 146 (500 feet north and south of the west tie-in), and obtaining cross sections along the existing railroad running through the project. Field surveying also included determining the elevations of the existing railroad running at the railroad bridge over SH 146 and confirming (spot-checking) the lidar data in several accessible areas. The survey data was based on the NAD 83, Texas Coordinate System, South Central Zone (4204) CORS adjustment. Elevations were based on the NAVD 88 2001 adjustment relative to the lidar data. The survey information was provided in MicroStation Select Series 10. At a Glance 3.7 Miles $140 million Construction Cost Services Service Markets Market

FM 2818 (Harvey Mitchell Parkway) Improvements

FM 2818 (Harvey Mitchell Parkway) Improvements College Station, Texas The FM 2818 (Harvey Mitchell Parkway) project in College Station is a story of innovation, collaboration, and technical excellence. DCCM led the team that worked closely with the City of College Station, TxDOT, Texas A&M University, and Easterwood Airport to address the region’s rapid growth and evolving transportation needs. Our journey began with a comprehensive corridor study and traffic analysis, which revealed that traditional intersection designs would not provide the necessary capacity or operational improvements. In response, we expanded our analysis to include six additional alternatives and ultimately selected an innovative “superstreet” (Restricted Crossing U-turn) design. This approach reduced signal phases at intersections, improved traffic flow, and provided flexibility for future upgrades to a controlled access facility. Our scope included data collection, accident and traffic analysis, environmental documentation, public involvement, identification of right-of-way (ROW) and easements, utility coordination, and topographic surveying. We also managed a team of eight subconsultants for specialized analyses and design tasks. We completed both the schematic and PS&E phases for FM 2818, developing a geometric design schematic from Wellborn Road to F&B Road, and seamlessly transitioning into detailed construction documents. The final schematic design was coordinated with the parallel PS&E design team, enabling construction documents to reach 60% design before schematic finalization. This efficient transition was made possible by keeping most of the same key staff and maintaining a strong project management plan throughout both phases. One of the most significant challenges was the presence of a major underground electric duct bank that conflicted with the proposed curb line and storm sewers. By conducting precise SUE QL-A potholing and collaborating with the city and TxDOT, we developed a solution that allowed the duct bank to remain in place while relocating the storm sewer, avoiding major disruptions and keeping the project on schedule. Another challenge arose when a new overpass at Jones-Butler Road was added late in the design process. Our team quickly adapted, revising schedules and resources to incorporate the new structure without impacting the letting date. Environmental considerations were also paramount. White Creek, which runs parallel to the corridor, required careful coordination to minimize impacts to the floodplain and wetlands. Through detailed grading, innovative barrier design, and close collaboration with regulatory agencies, we kept wetland impacts below permitting thresholds and avoided additional ROW acquisition. The FM 2818 project is now under construction. The result is a safer, more efficient, and future-ready corridor that supports the continued growth of College Station and the surrounding community. Traffic Analysis/Corridor Study Services DCCM performed a corridor study for FM 2818 from George Bush Drive to Wellborn Road. The study examined various alternatives, including many different intersection configurations. Ultimately, the conventional intersection designs failed to provide adequate operations. As a result, the superstreet concept was proposed and evaluated as a potential solution for the corridor. This provided the opportunity to reduce signal phases at intersections while maintaining the flexibility to upgrade the corridor to a controlled-access facility in the future should the need arise. Responsiveness: The original scope included an analysis of three options for access management along the corridor, none of which provided adequate capacity. To keep the project on schedule, the DCCM team worked with the City of College Station and TxDOT to identify and analyze six more options before the change order was processed. The innovative intersection used in the final design was one of these six additional options. Surveying Services During the S&E phase, DCCM provided a comprehensive topographic survey on this City of College Station/TxDOT street design project. The route was a 1.8-mile section of the existing state highway roadway. The extra width of the ROW created an unusually large, 80-acre project area, with several acres of native trees and brush. Using baseline survey points and information from the early 1970s, the ROW lines were accurately fitted to the topographic survey. Additionally, Baseline | DCCM had surveyed utility easements along the highway over 15 years prior, before any of the adjoining apartment complexes were developed. Schematic Design Services DCCM developed a geometric design schematic for FM 2818 from Wellborn Road to George Bush Drive. The project scope included conceptual and schematic design, data collection, accident and traffic analysis, conceptual design, schematic design, environmental documentation, public involvement, ROW/easement identification, utility coordination, project management, and topographic surveying. The initial scope included analyzing three design-year alternatives, developing a conceptual schematic for each, and developing the selected alternative through schematic design. Based on the results of the traffic analysis/conceptual design and meetings with City of College Station and TxDOT staff, it was determined that the three design-year alternatives would not adequately address growth issues along the project corridor; therefore, six additional alternatives were analyzed. Based on the traffic analysis and input from the City and TxDOT, a “super street” option was selected and developed through schematic design. SUE Services Under the SUE department’s TxDOT contract, the Bryan District requested that SUE QL-B designation be performed for their 3.2-mile FM 2818 Improvement project. More than 265,000 linear feet of utilities were identified on the project, resulting in a utility map that revealed numerous critical conflicts with the proposed roadway improvements. The designers and utility coordinators asked for 24 SUE QL-A test holes. All test holes were completed, the SUE QL-B designation and the conflicts it revealed were validated, and the designation was assigned. An additional SUE QL-B was requested for the downside streets to fully understand the utility impact. This project faced challenges, including complex traffic control and Texas A&M mowing the TxDOT ROW before each home football game. It was critical to complete the survey work each week before the Friday afternoon mowers arrived.
