Forensic Engineering & Expert Witness Services
A full evaluation of distress typically involves a review of construction documents, including soils reports, and building and grading plans; review of published and unpublished geologic maps and reports; stereoscopic review of aerial photographs; interior and exterior documentation of distress; manometer (floor level) surveys of building slabs; subsurface exploration; laboratory testing; data analysis; formulation of repair recommendations; and report preparation.
Subsurface exploration typically requires the use of truck-mounted or portable drilling equipment or hand-digging. Such excavations are performed under the supervision of our engineers or geologists. Following excavation, holes are carefully backfilled and landscaping or hardscape is restored as closely as possible to its original condition. Our modern testing laboratories are fully equipped and accredited by CCRL and AASHTO as well as by several local and state agencies.
Forensic evaluations can be performed to evaluate:
- Landsliding and slope stability, including landslide geometry and geologic structure
- Flooding and mudflows
- Ground shaking, liquefaction, lateral spreading, and settlement
- Groundwater seepage and moisture intrusion
- Construction and changed conditions claims

- Ground settlement associated with soil compaction and collapsible soils
- Expansive soil distress
