Independent forensic investigation of construction defects — design errors, workmanship failures, material deficiencies, and code compliance.
Construction defect forensic investigation identifies and evaluates design errors, workmanship failures, material deficiencies, and code non-compliance. PE-stamped reports support construction defect litigation, insurance claims, and remediation for commercial and residential construction.
Design Errors
Inadequate structural calculations, undersized members, insufficient connections, or failure to account for loads, soil conditions, or environmental factors in the engineering design.
Workmanship Defects
Poor concrete placement, inadequate welding, missing fasteners, improper flashing, or deviation from engineered plans during construction.
Material Deficiencies
Substandard materials — low-strength concrete, undersized steel, defective lumber, or failing sealants — that do not meet specifications or code.
Code Non-Compliance
Construction that does not meet applicable building codes — including structural, life safety, accessibility, and energy code requirements.
Inadequate Supervision
Insufficient inspection and quality control during construction allows defects to go undetected and uncorrected before they become concealed.
Change Order Errors
Field modifications, substitutions, or value engineering changes that compromise structural integrity without engineering review.
Schedule Pressure
Rushed construction — inadequate curing time, premature loading, or skipped inspections — leads to defects that may not appear for years.
Document review — construction documents, specifications, change orders, inspection reports, and warranty claims.
Comprehensive visual survey documenting all observed distress, defects, and deviations from plans.
As-built comparison — measuring actual construction and comparing to engineered plans and specifications.
Material testing — extracting cores, coupons, and samples for laboratory analysis of strength, composition, and compliance.
Code compliance review — evaluating construction against applicable building codes and standards.
Construction sequence analysis — reviewing inspection records, daily reports, and construction timeline.
Structural analysis — evaluating whether defects compromise structural capacity or performance.
PE-stamped report with defect identification, causation, significance, and remediation.
Plan Deviations
Differences between as-built conditions and engineered plans — missing reinforcement, incorrect member sizes, or altered connections — reveal construction defects.
Material Test Results
Laboratory testing revealing substandard concrete strength, deficient steel properties, or non-compliant materials provides objective evidence of defects.
Distress Patterns
Cracking, deflection, water intrusion, and deterioration patterns correlate with specific construction defects — the pattern reveals the underlying cause.
Inspection Record Gaps
Missing or inadequate inspection records, failed inspections, or unverified corrections indicate quality control failures during construction.
Construction Documentation
RFI responses, change orders, submittals, and daily reports reveal construction decisions and modifications that may have introduced defects.
✗ If the building passed inspection, there are no defects.
✓ Building inspections focus on code minimums and may not catch all defects — especially concealed conditions, material substitutions, or long-term performance issues. Engineering investigation goes beyond inspection to identify defects.
✗ Construction defects are always the contractor's fault.
✓ Defects can result from design errors, material failures, owner-directed changes, or a combination of factors. Independent investigation allocates responsibility based on evidence, not assumption.
✗ If there's no visible damage, there's no defect.
✓ Many construction defects are concealed — missing fireproofing, inadequate connections, improper flashing — and may not cause visible damage for years. Investigation with destructive testing may be needed.

Remediation scope and methodology recommendations
Construction defects in commercial buildings affect safety, performance, and asset value. For property owners and developers, an independent investigation provides the documentation needed for construction defect litigation, insurance claims, and remediation planning. PE-stamped reports carry legal authority that contractor inspections do not.
Construction defect cases involve multiple parties — designers, contractors, subcontractors, suppliers, and developers. Key considerations: identifying specific defects, allocating responsibility among parties, differentiating design from construction from material causes, and quantifying repair costs. Dr. Mousavi's reports provide clear causation opinions for multi-party litigation.
Construction defects may be covered under builders risk, CGL, or professional liability policies depending on the nature and timing. Key considerations: differentiating defective work (may be covered) from inherent defect (typically excluded), and determining whether resulting damage is covered even if the defect itself is not. Our PE-stamped reports provide the causation analysis.
Independent engineering answers about construction defects
Statutes vary by state — typically 2-10 years depending on the jurisdiction and claim type. However, the discovery rule may extend the period if defects were concealed. Consult an attorney for specific limitations; engineering investigation should begin as soon as defects are suspected.
Yes. Many defects — inadequate connections, missing fireproofing, improper flashing, substandard concrete — are concealed behind finishes and may not cause visible symptoms for years. Destructive investigation may be needed to identify hidden defects.
By comparing as-built conditions to engineered plans, testing material properties, reviewing construction documentation, and analyzing the failure mechanism. If construction matches the design but the design is inadequate, it's a design defect. If construction deviates from adequate plans, it's a construction defect.
