What S&B Engineers and Constructors does
S&B Engineers and Constructors, Ltd. is a privately held, Houston-based engineering, procurement, and construction (EPC) firm founded in 1967 that delivers complex industrial facilities under single-point accountability. Its integrated EPC model combines engineering, procurement, construction, and safety services — with optional standalone engineering, construction management, or reimbursable/EPCM engagements — targeting midstream operators, refiners, petrochemical producers, energy transition developers, power and industrial customers, terminals, pulp and paper manufacturers, maritime/government clients, and advanced recycling operators. The company's technology stack centers on direct-hire craft labor (rather than subcontracted), modularization and constructability studies, a 54-acre Baytown, Texas fabrication facility with CLOOS robotic welding, plasma-pipe cutting, X-ray bays, and a 100-ton mobile gantry crane, plus an integrated U.S.-India engineering delivery model (Noida, India office with 120 added employees and Vishakhapatnam maritime team) for 24/7 project execution.
S&B generates revenue primarily through fixed-price (lump-sum) and reimbursable EPC contracts for large industrial projects, with supplementary revenue from standalone engineering and construction services, fabrication and modular assembly sold both internally and externally, and maritime engineering through the TAI Engineers subsidiary. Go-to-market is exclusively direct enterprise field sales — no channel partners or PLG — with the commercial team led by Chief Commercial Officer Greg Hafer pursuing competitive bids and relationship-driven wins with major industrial owners. The S&B family of companies includes wholly-owned subsidiaries Ford, Bacon & Davis (oil and gas, industrial, power, and renewables, integrated January 2022), TAI Engineers (maritime, acquired May 2021), S&B Fabrication Services (formerly S&B Modular Operations), S&B Infrastructure, Ltd., and a majority stake in Bibb Architects, Engineers and Constructors (acquired August 2021). The firm employs more than 4,500 people across the United States and India and was recognized by ENR as No. 10 in the Oil & Gas sector on the 2026 Top 400 Contractors list, No. 1 in Power (Hydrogen), and No. 2 in Oil & Gas (Refineries and Petrochemical Plants) on the ENR 2024 Top 500 Design Firms. Notable customers include Chevron Phillips Chemical (world's largest on-purpose 1-hexene unit, C3 splitter), Plug Power (largest U.S. electrolytic liquid hydrogen plant, completed March 2024), Smackover Lithium (EPCC for Central Processing Facility, May 2026), and New Hope Energy (420 MT/day advanced recycling project).
