Systems Engineering and Forensic Services in Chula Vista's Eastlake district is a forensic engineering consulting firm incorporated in 2012, with operational roots tracing to the late 1990s and led by a California-registered P.E. holding a Diplomate in Forensic Engineering (D.F.E.) from NAFE. Litigation support and expert-witness testimony form the firm's primary service line, providing accident investigation and reconstruction analysis for crane, rigging, and material-handling cases — a caseload that regularly interfaces with South Bay litigation practices including The Sexton Law Firm. Specialization covers aerial devices, forklifts, conveyors, below-the-hook lifting devices, and hydraulic and pneumatic systems, with marine engineering credentials extending to stability analysis of floating dry docks, barges, and coffer dams. OSHA compliance audits and ASME B30 safety-code reviews supplement the investigative work, covering the same crane and rigging systems that general contractors deploy on multi-story projects — Sonny Builders among the Chula Vista firms managing heavy-lift sequences on active jobsites. Investigation methodology applies ASME, SAE, and ISO standards to reconstruct failure sequences in crane collapses, rigging failures, and material-handling system malfunctions through finite-element analysis and risk simulation modeling.
