Emergency Structural Repairs Restore X425 Bronx School Pool

Client: New York City School Construction Authority (NYCSCA)
Our Role: Construction Manager-at-Risk

A renovated indoor pool with eight repaired structural steel columns.

When structural deficiencies were discovered at an active Bronx school’s swimming pool, the New York City School Construction Authority (NYCSCA) declared a Red Dot emergency, requiring immediate action to protect more than 2,000 students and staff. As construction manager-at-risk, GFT led the emergency response, coordinating contractors, engineers, and school stakeholders to stabilize the structure and deliver critical repairs. Working within the constraints of a fully occupied school, the team carefully balanced safety, construction activities, and uninterrupted school operations while navigating complex site conditions and an accelerated schedule. The result was a fast, coordinated repair effort that prioritized student and staff safety without disrupting the educational environment.

Key Features

Mobilized onsite within two hours of the NYCSCA Red Dot emergency declaration.
Coordinated 24/7 construction operations around strict building occupancy requirements.
Redesigned shoring approach in response to geotechnical constraints caused by a high groundwater table and underground tributaries of the Bronx River.
Deployed real-time optical point monitoring with live notifications to track structural movement continuously throughout demolition and repairs.
Implemented staggered column repair strategy using multiple hydraulic jack systems to enable simultaneous column repairs.
Specified rapid-strength concrete mixes achieving 5,000 psi in five days, saving approximately 161 days of curing time across eight column repairs.
Managed approximately 60 special inspections for structural stability, welding, bolting, and concrete placement.

Outcomes

Completed major construction eight weeks ahead of the original 24-week schedule, a 33% reduction in construction duration.
Delivered under a time-and-materials contract with zero change orders, claims, and safety incidents.
Maintained safe, uninterrupted school operations throughout the emergency repair process.
