Background
A commercial warehouse facility reported structural concerns after visible deterioration was observed in primary steel framing members. ClearLine Forensics was retained to evaluate the extent of deterioration and determine contributing factors.
Investigation
Engineers conducted a full structural assessment including visual inspection of all exposed steel framing members, measurement of section loss, evaluation of protective coatings, and review of building maintenance records.
Particular attention was given to connection details and load-bearing capacity.
Key Findings
Beam Condition
Primary I-beam flanges showed significant delamination and section loss exceeding 30% in multiple locations, compromising load-bearing capacity.
Corrosion Pattern
Deterioration patterns were consistent with prolonged moisture exposure from a failing roof drainage system, not structural overloading.
Maintenance History
Building maintenance records revealed the roof drainage system had not been serviced in over 8 years, allowing persistent water intrusion onto structural members.
