MarcorSEN Engineering / Services
Three connected practice areas.
Years of experience.
Forensic engineering, expert witness testimony, and specialty practice — delivered personally by Marcor Platt, PE, SE. Each engagement is led end-to-end by a single PE/SE-licensed practitioner with 700+ reports authored and trial-tested testimony in federal and state courts.
Expert testimony that survives cross-examination.
Over 700 forensic reports and trial-tested testimony in federal and state courts. Engagements begin with conflict checks and end with verdicts — every step documented to the standard that holds under rigorous examination.
Explore Expert WitnessForensic engineering that works backward from the failure.
Root-cause analysis for construction defects, natural-disaster damage, water intrusion, fires, and foundation failures. Each investigation links observed damage to causative events through documented evidence and applicable codes.
Explore Forensic EngineeringSpecialty engineering across the failure spectrum.
Four dedicated focus areas — hydrology & hydraulics, natural disaster impact, building code & project-management forensics, and man-made disaster causation — covering the failure modes most often driving litigation and insurance disputes.

Specific deliverables that turn site evidence into courtroom-ready opinions.
Within the three practice areas above, engagements typically include one or more of the following specific deliverables. Each is scoped to the dispute at hand and documented to the standard required for deposition or trial.
Truss Repair vs. Replacement Decisions
Pre-engineered metal-plate-connected truss assessment — quantifying observed damage, residual capacity, and whether repair, sistering, or replacement is the appropriate remedy under the applicable code.
Structural Adequacy for Wind Forces
Component-and-cladding and main-wind-force-resisting-system analysis to determine whether an as-built structure satisfies the wind loads required by ASCE 7 and the IBC at the relevant code cycle.
Wind-Driven Water Intrusion Analysis
Reconstruction of storm wind and rain exposure, envelope performance, and the path of water infiltration — separating wind-driven rain claims from pre-existing envelope or maintenance failures.
Underground Engineering Feasibility
Feasibility, design, and cost evaluation of underground utility infrastructure — including transmission-line work supporting expert testimony before the California Public Utilities Commission.
Project Cost Estimates
Independent cost estimates for repair, remediation, and remediation alternatives — built up from quantity takeoffs, regional unit pricing, and constructability review rather than insurance-software defaults.
Continued-Use Suitability Opinions
After-fire, after-impact, and after-settlement determinations of whether a damaged structure can be safely occupied or returned to service — and under what conditions and limitations.
