What Sapphire Engineering Company, Inc. does

Sapphire Engineering Company, Inc. (SECI) is a privately held structural and civil engineering consulting firm founded in 2004 by principal engineer Shahzain Husain, P.E. and headquartered in Westlake Village, California. The company provides integrated construction consulting services spanning structural engineering, civil engineering, construction management, plan review for county building departments, temporary earth shoring design, and seismic retrofit work. Project scope spans tenant improvements of a few thousand square feet to ground-up new construction valued up to approximately $40 million, with a documented track record across commercial, residential, healthcare, educational, and entertainment facilities in Southern California.

The firm operates as a professional services practice with a relatively flat operating model. It maintains a small multidisciplinary team of roughly six people covering structural, civil, and construction management functions, supplemented by its 2024 hire of Vice President Arif Shamim (PE SE MBA), who brought 30 years of structural engineering experience and OSHPD/DSA regulated-work credentials. Technical capabilities include complete structural design and analysis, peer/plan review for Los Angeles County Building and Safety (covering architectural, fire safety, exiting, and structural requirements), shoring design using rakers, tie-backs, and cantilevered pile systems, and civil site work such as retaining walls, drainage, grading, erosion control, and SUSMP compliance. Service delivery is project-based and quote-based, with no publicly disclosed pricing or packaged offerings.

The go-to-market model is direct client engagement through the company website, phone, and email, supplemented by referrals from architecture firm partners. The firm is a member of SEAOC and ASCE, which provide industry credibility and networking channels. The customer base is a heterogeneous mix of residential developers (e.g., D.R. Horton, Vintage Homes), luxury residential architects (e.g., Marmol Radziner, Van Tilburg Banvard & Soderbergh), construction groups, and institutional clients (Pepperdine University, Universal Studios Hollywood, Tarzana Medical Offices). The company has no disclosed funding, no app or API product, no patents, and no digital platform component; revenue is generated entirely from professional services fees.
