Procurement Projects

IH35NEX, Bexar County

The Texas Department of Transportation (TxDOT) and the Federal Highway Administration (FHWA) propose improvements to Interstate Highway 35 (I-35) in South Central Texas from I-410 South in San Antonio to Farm-to-Market (FM) 1103 in Schertz. The proposed project would add capacity in the form of elevated managed lanes. In addition, proposed direct connectors would link the managed lanes to the existing I-410 South, I-410 West, and Loop 1604 facilities. The proposed project, generally referred to as the I-35 Northeast San Antonio Expansion Project, is located in Bexar, Guadalupe, and Comal Counties.  Cities and towns within the study area include San Antonio, Windcrest, Live Oak, Universal City, Selma, Schertz, Kirby, and Cibolo. The construction limits of the project account for transitions into the existing roadways and extend approximately 2.8 miles south of the project begin at I-410 South to just south of Copeland Drive, and extend approximately 1.3 miles north of the project end at FM 1103. In support of efforts to reduce project construction costs while maintaining an acceptable return on the investment, SLG studied alternative project scenarios by looking at revised direct connector alignments and designing cross-over bridges to allow potential elimination of portions of the managed lanes.  Also, assisted in development of revised quantities and cost estimates for the project.

US 281, Montgomery, Bexar County

The need for improvements to the US 281 project corridor stems from historic and continuing trends in population and employment growth along the corridor and within the surrounding areas. This proposed eight mile segment, between LP 1604 and Borgfeld Drive, doubles the number of existing lanes and completes direct connections with LP 1604. This project is an integral part of the San Antonio-Bexar County MPO’s long-range transportation plan. Under this WA, led efforts for development of project technical provisions, participated in alternative technical concept evaluations, assisted in design review of project schematics, supported the development of preliminary cost opinions for construction and maintenance and attended working group meetings as needed.

SH 99 (Grand Parkway) Sections H, I-1 and I-2, Montgomery, Harris, Liberty and Chambers County

State Highway 99 (the Grand Parkway) is a proposed 180-mile circumferential highway traversing seven counties in the Greater Houston Area. It is divided into 11 Segments designated A through I-2. For Segments H & I-1, the alternative alignments were developed within the project area to fulfill the need for and purpose of the project, to minimize potential environmental impacts, and to respond to public/landowner and resource agency comments. Project required engineering support and feasibility review services under a procurement contract for SH 99 from near US 59 to SH 146. Under this WA, assisted in design review of project schematics and supported the development of preliminary cost opinions for construction and maintenance.

SH 249, Montgomery and Grimes County 

Project required design assistance and supplemental services under a procurement contract for SH 249 Preliminary Studies from near FM 149 in Montgomery County to SH 105 in Grimes County. Under this WA, assisted in development of preliminary cost opinions and prepared necessary presentation materials, reports and exhibits to support the above tasks.

Loop 20, Webb County 

Project required design assistance and supplemental services under a procurement contract for the Loop 20 expansion Project from IH 35 to US 59 in Laredo. Under this WA, assisted in development of route alternatives, design criteria and preliminary cost opinions; assisted in coordination with project stakeholders; reviewed existing and proposed

ROW for compatibility with design and identified potential constraints; conducted design criteria analyses for the project limits; identified potential cost saving solutions; and prepared necessary presentation materials, reports and exhibits to support the above tasks.

Loop 375, El Paso County

Project required design assistance and supplemental services under a procurement contract for the Loop 375 Border Highway West Extension Project from Racetrack Dr. to US 54 in El Paso. Under this WA, assisted in development of technical provisions, design criteria and preliminary engineering documents; assisted in the development of RFQ documents for potential responders; assisted in coordination with project stakeholders including the BNSF Railroad, U.S. Customs and Border Protection and area utilities; assisted in determinations of limits of operations and maintenance; conducted design criteria analyses for the project limits; distributed information through the project e-mail site and monitored for questions and responses; identified potential cost saving solutions; and prepared all necessary presentation materials, reports and exhibits to support the above tasks. Involvement continued through the escrowed document review and into miscellaneous support during the construction phase.

Loop 1604, Bexar County

Project required design assistance and supplemental services under a procurement contract for the Loop 1604 Western Extension Project from FM 471 to SH 16. Under this WA, assisted in development of technical provisions, design criteria and preliminary engineering documents; evaluated alternate project configurations; assisted in completion of

design exception requests; reviewed existing and proposed ROW for compatibility with design and identified potential constraints; reviewed and updated probable construction and maintenance costs; identified potential cost saving solutions; and prepared all necessary presentation materials, reports and exhibits to support the above tasks.

IH 35E, Dallas/Denton Counties

Project required design assistance and supplemental services under a procurement contract for improvements to over 28 miles of IH 35E from just north of IH-635 in Dallas to US 380 in Denton. Under this WA, reviewed and updated probable construction and maintenance costs for the initial Phase 1 construction project and for ultimate configuration

improvements. Cost determinations for the ultimate configuration required the analysis of schematic design alongside PS&E plans to determine what improvements could remain and what would have to be rebuilt. Tasks included preparation of all necessary documentation and exhibits to support the estimates.

SH 183/Loop 12/SH 114, Dallas/Tarrant Counties

Project required design assistance and supplemental services under a procurement contract for improvements to over 26 miles of SH 183 east of SH 121 to IH 35E; Loop 12 at SH183 to IH 35 E; and SH 114 east of International Pkwy. to SH 183. Under this WA, reviewed and updated probable construction and maintenance costs for all phases and segments of construction. Tasks included preparation of all necessary documentation and exhibits to support the estimates.
