Stridde, Callins & Associates

What Stridde, Callins & Associates does

Stridde, Callins & Associates, Inc. (SCA) is a private mechanical, electrical, and plumbing (MEP) consulting engineering firm headquartered at 342 S Navigation Blvd, Corpus Christi, Texas, in continuous operation since its founding in 1956 by Mr. Jack Callins. The firm employs 11-50 technical and support staff and operates from a single South Texas office, serving K-12 school districts, colleges and universities, county governments, port authorities, cultural institutions, and private industry clients across the region. SCA's leadership is concentrated among its principals: Scott Stridde, P.E. serves as President and Jared Merdes, P.E., MBA, LEED AP as Vice President, with direct principal involvement in technical design across all engagements.

The firm's core offerings are organized into four integrated service lines: Mechanical/HVAC Engineering (including building automation and commissioning), Electrical Engineering (distribution, emergency generation/transfer, lighting, fire alarm, and lighting controls), Plumbing Engineering (sanitary, water, gas, sprinkler systems), and Arc Flash Studies (incident energy analysis, one-line diagrams, NFPA 70E/OSHA compliance). Its value proposition rests on a self-described unique composition of licensed P.E. design professionals and licensed construction tradesmen, claimed to produce the lowest change-order volumes in the industry and complete, constructible contract documents. SCA markets no proprietary technology platform or software product; it operates as a pure professional services consulting practice, with projects executed as part of design teams alongside architects and general contractors under standard MEP fee structures.

SCA's revenue model is project-based professional services billing for consulting engineering engagements, with scope-driven pricing (no public rate cards) and customer acquisition driven by reputation, direct relationships, and architect/general-contractor referrals. The customer mix is heavily weighted toward institutional and government clients in South Texas, including repeated engagements with multiple independent school districts (Gregory-Portland ISD, Flour Bluff ISD, Calallen ISD, Victoria ISD), Del Mar College and Victoria College, Victoria and Nueces Counties, and the Port of Corpus Christi. The firm is privately held with no institutional investment, parent company, or subsidiaries disclosed.
