The challenge

Mold across an active headquarters campus

The Caribbean Development Bank's campus in Wildey, St. Michael had mold affecting multiple buildings, including offices, a registry documents room and the Conference Center. Work had to proceed with oversight from the bank's consulting engineer, Consulting Engineers Partnership Ltd (CEP), and with minimal disruption to bank operations.

The project was completed by Preven-Tech.

CDB headquarters building, Wildey, St. Michael
Before & during

What we found, and how we contained it

Before: inspection findings

During: containment & air filtration

Our approach

From inspection to verified clearance

Inspect & test

On-site inspection, moisture mapping and lab air and surface sampling of each building, followed by a remediation plan presented to the bank's board.

Plan the zones

Floor-by-floor containment zone maps and a phased, building-by-building schedule, so each area could be isolated and treated in sequence.

Contain

6-mil poly containment, ZipWall barriers and zippered entries, critical barriers on vents and doors, and sealed HVAC supplies and returns.

Remediate

Removal and cleaning to the IICRC S520 standard, with detailed micro-cleaning of surfaces and contents. A second crew was added at the bank's request to expedite.

Verify

Post-remediation verification by air spore-trap sampling: indoor levels at or below the outdoor control, with no atypical species.

Correct the cause

Building B envelope and waterproofing correction with our construction partner Professional Roofing, certified complete by CEP.
