What T & B Engineering Inc does
T & B Engineering, Inc. is a privately held structural engineering firm headquartered in Riverside, California, with origins traceable to co-founder Jesus Torres's 1989 graduation from Cal Poly San Luis Obispo. The firm operates from a six-county Southern California footprint (Riverside, Los Angeles, Orange, San Bernardino, San Diego, and Ventura) and delivers four integrated service lines: Design Services (structural design, analysis, and construction documents), Inspections and Assessments, Retrofitting and Rehabilitation (including seismic retrofitting), and Construction Support. Its technical stack centers on RAM Steel for structural modeling and Revit and AutoCAD for BIM-driven drafting, with deep expertise across wood, steel, reinforced concrete, masonry, and light-gauge metal framing.
The firm's client base is heavily concentrated in California public K-12 and higher education, evidenced by named projects with Los Angeles Unified, Long Beach Unified, Riverside Unified, West Covina Unified, California Baptist University, College of the Canyons, and Pierce College, plus a stated 60+ school district relationships. The firm has secured the first Division of State Architect (DSA) approval for Insulated Concrete Forms (ICFs) in a California public school gymnasium at Hollencrest Middle School. Leadership rests with President Mark Ballou (strategic and RFP oversight), Principal Peter Ravenkamp, P.E., S.E. (engineering execution, 19 years of experience), Senior Project Engineer Raymundo Lozano, P.E. (8+ years), Project Manager and BIM Specialist Mark Erlendson, and Accounting & Marketing Manager April Flores.
Revenue is generated through project-based professional services fees on a quote-based pricing model, with no disclosed financials, no outside funding, and no parent company involvement. Business development runs through RFP responses, direct architect and contractor relationships, an active company blog, and LinkedIn presence. The firm is independently owned following the 2018 death of co-founder Jesus Torres, with Mark Ballou and Peter Ravenkamp as the current operating principals.
