Window replacement: a thoughtful, energy-saving transformation
As the architectural and engineering partner for Red Hook Central School District’s multi-year window replacement program, Tetra Tech developed a design solution that improved comfort, durability, and energy performance across the District campus. The firm recommended replacing the original large, single-glazed windows from the 1960s with dual-glazed, high-performance glass in thermally broken frames to reduce solar heat gain, limit air infiltration and water leaks, and improve HVAC efficiency.
To manage the scope and logistics of work across multiple schools, Tetra Tech developed a smart contracting and phasing strategy that balanced schedule, competition, and constructability. Recognizing that a single contractor taking on all scopes would be unrealistic, Tetra Tech broke the project into school-specific bids and separated elementary from middle/high school scopes, issuing two window contracts alongside general contractor contracts. This approach broadened the pool of bidders, enabled contractors of varying sizes and capacities to participate, mitigated supply-chain pressures, and preserved a summer-focused construction schedule. Phasing the work over two summers accommodated long lead times and substantial shop-drawing requirements while minimizing disruption during the school year and producing favorable pricing for the district.
When unforeseen field conditions emerged—such as at Mill Road Elementary, where existing drawings did not align with actual site conditions and flashing-to-window interfaces required redesign—Tetra Tech’s experienced design and field teams responded quickly and effectively. The firm activated planned contingencies, performed targeted destructive investigations and asbestos testing as needed, and worked closely with mechanical staff to resolve interface and sequencing challenges with minimal disruption. Tetra Tech’s deep familiarity with the district’s facilities, combined with its hands-on field expertise, was instrumental in keeping the project on schedule. With major work completed at the middle school and continued progress at the high school, the district is well positioned to benefit from improved comfort, lower energy use, and a more resilient building envelope for years to come.
By combining strategic phasing, responsive field support, and high-performance design, Tetra Tech helped transform an aging window system into a long-term asset for the district.
