About TSI Engineering, Inc.
TSI Engineering, Inc., a North Highlands, California-based minority-owned small business, is a SBA-certified 8(a) Program Participant and HUBZone firm that specializes in delivering construction, renovation, and facility maintenance services to federal agencies. The company provides civil engineering, general contracting, and infrastructure improvement services with demonstrated expertise across multiple government entities. TSI Engineering has established itself as a strategic partner for the Department of Defense and civilian agencies through both competitive and set-aside contracting vehicles, leveraging over 60 years of combined experience in delivering complex infrastructure projects.
TSI Engineering's federal contract portfolio encompasses a diverse range of construction and maintenance services across multiple agencies and project types. The company has executed definitive contracts and delivery orders with the U.S. Air Force's Air Mobility Command for extensive base maintenance work at Travis Air Force Base, including base-wide painting services, sewer system repairs, dormitory painting, and traffic survey sign installation and repair. Notable projects include a $916,786 firm fixed-price contract for sewer system repairs in the 400 area of Travis Air Force Base (awarded September 28, 2022, set aside under the 8(a) Sole Source program) and a substantial $8,605,263.51 HUBZone set-aside contract with the Federal Highway Administration for the China Beach Access Road reconstruction project in San Francisco, which encompassed parking lot construction, drainage systems, retaining walls, trail construction, and utilities work. The company has also performed significant infrastructure work for the U.S. Army Corps of Engineers, including a $5,135,504.05 total small business set-aside contract for the Natomas Reach B levee repair and roadway improvement project in Sacramento, California. Recent delivery orders from Air Mobility Command in 2025 demonstrate continued engagement, including awards valued at $950,940.43 for Building 1 exterior paint and patch work, $562,289.32 for Building 249 exterior painting, $228,339.04 for Building 1301 exterior painting, and $235,096.93 for base-wide painting services. The company has also received contracts from the Federal Highway Administration and worked with the National Park Service on infrastructure projects, consistently performing as the prime contractor with firm fixed-price arrangements.
TSI Engineering currently holds a single-award 8(a) sole source Indefinite Delivery Contract with the U.S. Air Force's Air Mobility Command, awarded September 23, 2024, with a ceiling value of $4,500,000 and a period of performance extending through September 22, 2029. This IDV requires the contractor to provide all labor, materials, and supervision for base-wide painting services at Air Mobility Command installations in accordance with the base Statement of Work and individual task order Statements of Work requirements. This indefinite delivery vehicle has served as the parent contract for multiple task order awards issued throughout 2024 and 2025, enabling Air Mobility Command to efficiently procure painting and facility maintenance services across the fiscal year without individual competitive procurements. The substantial task orders issued under this IDV demonstrate the Air Force's confidence in TSI Engineering's capacity and performance, with cumulative delivery order values exceeding $2.8 million to date, indicating robust utilization of the contract vehicle for the command's base maintenance priorities.
