An architect & contractor who brings expertise & experience in both architecture & construction. More than 30 years experience in design and building single family homes & commercial structures.

As an expert witness and litigation consultant on issues involving residential and commercial buildings, I work on cases that involve an array of issues:

Architectural Analysis — code compliance, construction defects, research into historic building codes or research into the historic element of a building.

Forensic Construction Investigation — develop the “story,” such as slips and falls involving building code issues; Americans with Disability Act (ADA); or such construction defects as missing handrails and guardrails; leakage; detection of faulty construction; and why a building has failed.

Analysis of Construction Defects and Construction Documents — building codes; design flaws; errors; failure (leaks, slips and falls); architectural standards of care; and discovery of plan defects.

Building Plan Interpretation — codes, architecture standards of care, defense of architects and contractors, plan defect analysis.

Leak Intrusion — waterproofing, weatherproofing components

Repair Drawings and Specifications —repair drawings and specs for remediation of defects; and construction administration of remedial work.

Other legal issues I work on:

Property line disputes, Employer and/or Property Manager duties to provide safe working environment (EDD, CAL/OSHA), Site visit with detailed reports, including photography (print/digital), and video Courtroom/Deposition models and exhibits.

John Rohosky functions as construction sleuth, when the situation requires a thorough
& responsive expert.
