PS 206 School Construction Authority Sheepshead Bay Brooklyn We provided the required A/E Services for a $5.2 M full roofing replacement that included rebuilding all parapets and custom cast copings, installing copper ledge covers and flashings at stone balconies, water tables and front portico, and replacing historic ornamental iron railings and sidewalk vault waterproofing. All of our work was reviewed with and approved by the New York State Historic Preservation Office.
Being in close proximity to the Long Island Sound, this building was exposed to severe weathering over the last 100 years, with poor maintenance of the exterior envelope evidenced by water infiltration in all top floor classrooms. The original design incorporated numerous ventilation shaftways topped by copper louver grilles which had provided a pathway for wind-driven rain. We rebuilt top of the shaftways with hurricane proof louvers. Where the classrooms along the east elevation were ridden with leakage, we rebuilt the parapets and brick and stone masonry, integrating thru-wall copper & rubberized waterproof membranes.
A science lab had to be dismantled and reinstalled in order to replace a reinforced concrete floor that was in danger of failure due to corroded internal reinforcement. The central bulkhead structure containing HVAC equipment and boiler chimney also had to be reconstructed. At the entrance to the building, we restored the columned entrance portico, replaced marble steps railings, repaired ADA ramps and reconstructed the portico roof to halt leakage into the principal's office.
This was one of six schools assigned to our firm under a 5-year term contract with the School Construction Authority. Our office completed all phases of design and construction-related services on these projects; the budgets for each school ranged from $1.2 to $6.2 million dollars for construction costs. Our responsibilities began with detailed surveys and scope reports to establish the budget and scope of each project. We then took each project through to construction documents, bidding, construction administration and close-out. Our exterior envelope work addressed brick and stone masonry repointing and replacement, parapet and bulkhead rebuilding, and roofing replacement. We also renewed outdoor sports and play areas.
Interior renovation work included general redesign/reconfiguration of interior spaces as well as structural repairs, plaster/paint refinishing of walls, upgrading restrooms to ADA compliance, creating early childhood restrooms, replacing auditorium ceiling and lighting, rebuilding a stage, retrofitting of existing systems, piping and drainage replacement, and grout injection waterproofing to eliminate flooding.
