Construction Defect Investigation
Independent investigation of defective construction: foundations, framing, drainage, concrete and site work.
What the work involves
When a new home, building or site improvement performs poorly, an engineer investigates whether design or construction departed from plans, codes and industry standards. Work includes document review, inspection, measurements, destructive testing where needed, and a report on causes and repair costs. Reports support warranty claims, negotiations, and litigation, and many states have right-to-repair statutes that set notice steps before suit.
Local conditions we plan for
- Crumbling concrete foundations caused by pyrrhotite in aggregate (northeast Connecticut)
- Coastal flooding and hurricane storm surge on Long Island Sound
- Aging infrastructure and older housing stock
- Frost heave in glacial till soils
Building code: 2021 IBC/IRC adopted at the state level (ICC adoption chart, April 2026).
When you need it
- Cracking, settlement or water problems in new construction
- Builder disputes the cause of a problem
- HOA transition study before taking control from a developer
- Warranty claim deadline approaching
