Large-Loss Case Studies.

Challenge

Multi-floor smoke contamination plus suppression-water Cat 1 on upper floors with an already-published reopening date that wasn't moving.

Response

IICRC S700 + S500 dual protocol under one project manager. Soot classified by area (protein + wet smoke). Bar-coded contents pack-out across hundreds of guest-room inventories. Layered HEPA + thermal fogging + ozone deodorization with cycle-time logging.

Outcome

Reopened on the published date. Carrier documentation cleared first-pass review.

Challenge

Water intrusion past S500 thresholds with secondary mold growth behind vinyl wall base across multiple wings of an active occupied healthcare facility.

Response

ICRA 2.0 Class IV containment maintained continuously. Hard-wall barriers, full anteroom, -0.01 in. w.g. continuous negative pressure. Dual S500 + S520 documentation tracks. Daily Infection Prevention permit sign-off.

Outcome

Independent IEP clearance achieved before reconstruction. Zero patient or staff complaints.

Challenge

Emergency water intrusion at an active semiconductor facility — cleanroom environment, ESD-sensitive equipment, no tolerance for dust or residue at the protocol-specified clean class.

Response

ESD-safe drying. Corrosion neutralization on exposed metal surfaces. OEM-aligned cleaning protocols matching the facility's existing cleanroom specification. Continuous documentation for the carrier and the facility's quality-assurance audit trail.

Outcome

Production line cleared for reoccupancy at the original cleanroom class with documented chain of custody on every affected zone.

Challenge

Sewage backflow across three floors of a 32-unit multifamily complex. Category 3 black water per IICRC S500 — every porous material affected became regulated waste.

Response

Full HAZWOPER-certified extraction with regulated-waste disposal. Containment barriers. Two-step antimicrobial application per S500 protocol. Independent IEP clearance prior to reconstruction. Tenant communication coordinated with property management.

Outcome

Completed in 6 days. Zero long-term tenant displacement past the initial 48-hour stabilization window.

Challenge

Sprinkler head failure on floor 18 of a Class A office tower discovered overnight. Standing water across multiple suites, electronics and contents at risk, tenants returning at 7 AM.

Response

Crews on-site in 52 minutes. Water extraction concurrent with structural drying setup. Contents triage — electronics moved to drying chambers, papers prioritized for document recovery. Carrier notified with same-night photo timeline.

Outcome

Tenants returned to full operations by 7 AM. Documented dry-standard achieved within 5 days.

Challenge

Hidden moisture behind vinyl wall base discovered during a routine refurbishment. Memory-care residents in active occupancy. Visible Condition 3 mold across four wings.

Response

Phased ICRA-aligned containment moving wing-by-wing rather than facility-wide. S520 protocol with HEPA negative-air filtration in each phase. Resident communication coordinated with the facility's family-services team. Third-party clearance testing per phase.

Outcome

Residents stayed in place throughout. Each wing handed back with written IEP clearance before the next phase began.

Challenge

Flash-flood intrusion through roll-up doors during a Phoenix monsoon event. 180,000 square feet of warehouse with high-value inventory and active distribution operations.

Response

Desiccant drying array sized to the cubic-feet load — multiple trailer-mount units running concurrently. Inventory salvage coordinated with the carrier and the facility's logistics team. HEPA filtration on exhaust air to protect adjacent occupied space.

Outcome

Distribution operations resumed in stages. Inventory salvage rate exceeded the carrier's pre-event reserve estimate.

Challenge

Structural kitchen fire with smoke migration into adjacent living spaces, custom finishes, and high-value contents. Like-kind-and-quality finish match required throughout.

Response

S700 protocol with protein-residue chemistry in the kitchen zone, wet-smoke chemistry in the adjacent areas. Contents pack-out for ozone treatment. Reconstruction with finish carpentry matching original specification.

Outcome

Completed in 11 weeks including reconstruction. Carrier-approved finish-match documentation.

Challenge

Cat 3 sewage across three floors of a 42-unit complex. S500 protocol required every porous material removed, antimicrobial applied, and clearance verified before reconstruction.

Response

Full S500 mitigation with documented psychrometrics. Two-step antimicrobial application. Coordinated tenant relocation per Arizona's 30-day rule with the property management team.

Outcome

Zero displaced tenants past day four. Full clearance documentation delivered to the carrier.
