This project involves a three-story building constructed in 1961, with a small building addition completed in 1965. The scope includes the replacement of all eight building roofs, implementation of a protective guard around the main roof, various flashing work, and selective masonry work on the facades. The scope of the project also includes the restoration of the existing building's exterior terracotta panels between windows. The proposed work of the terracotta panels involves selective replacement of panels, spall and crack repairs, a potassium silicate coating, and repointing.

This project involved a four-story building with a basement and cellar level, located in the Bushwick area of Brooklyn, New York. The original building was constructed in 1904, with a matching addition constructed in about 1924. The charge involved identifying potential causes and sources of water infiltration within the cellar of the school building, and providing a repair to reduce the overall water seepage into the below grade spaces. The scope of the project included windows, masonry, restoration, and complete roof replacement. For this project, an energy analysis was performed on adding 2" of additional roof insulation. As a result, 8" (in lieu of 6") of roof insulation was provided on this project. This resulted in raising all the bulkhead doors at the roof level.

The existing 1920 building was continuously experiencing water infiltration and moisture issues on the upper two floors. This project involved the replacement of all the existing roofs, including a play roof. In addition, in 1998 the roof side of all the parapets were covered with a metal lath and cementitious coating. The cementitious coating significantly spalled and cracked throughout. As part of this project, the cementitious coating and face brick was removed and face brick replacement was provided. Various selective exterior masonry restoration work was performed and interior plaster repair was provided to address the associated water damaged areas.

The existing 1995 building will undergo an exterior renovation to address deteriorated conditions, and includes reconstruction of an existing exterior ramp and retaining walls, and roofing assembly and coping replacement at low roofs, selective masonry restoration and repair, and painting of all existing site steel fencing, steel artwork, and window guards. Includes associated plumbing work.

The existing 1927 building is undergoing an exterior renovation to address deteriorated conditions, including complete roof replacement, selective masonry repairs and replacement, removal of a non-breathable coating on the exterior masonry, cellar epoxy injection and concrete repair work to address water infiltration, and site work including removal and reconstruction of areaway slabs and piping, repairs of an existing retaining wall, and exterior hatch door replacement. Includes associated plumbing and electrical work.

The existing 1958 building consists of a concrete superstructure with solid masonry exterior walls. The mortar joints throughout the building have weathered and deteriorated. This project involves repointing the entire building, complete roof replacement, and selective masonry restoration work. As the thickness of the roof insulation is being increased to 6", the existing parapets are being raised to comply with the minimum protective guard height requirement of the NYC Building Code. This project also includes the replacement of the existing unitized aluminum curtain wall system for the entire building. Probes were performed to determine the complete scope of work associated with the curtain wall replacement and design documents developed thereafter.

This project was initially an emergency project to address falling glass block on the exterior walls of the exit stairs. The scope of the project includes exterior masonry restoration work of the 1950 three-story building. The mortar joints on both sides of the existing parapets were deteriorated and a majority of the parapet coping stone joints were found to be open. The scope of the project includes the replacement of the glass block and frames in the exit stairs, repointing of the parapets (both sides), repointing of the coping stones, selective masonry restoration throughout the building, as well as the replacement of the third-floor roof playground safety surface.

This is an existing 1899 five story school with a 1918 three story addition.  The project involved probing and evaluating the falling masonry conditions, and to provide a design for the repair of such conditions.  The resulting $6.7M project involved an extensive masonry restoration project involving spandrel steel repairs, ornamental terracotta jack arch and jamb repairs and other selective masonry and window repair work.

This is an existing two-story building with a basement that was built in 1926.  The project involved evaluating the chronic water infiltration from the exterior walls and water infiltration at the basement level.  The resulting $3.1M project involved developing a design of a waterproof drainage plane within the collar joint of the existing exterior wall.  The project also involved composite replacement of a shingle roof with synthetic slate tiles with a snow retention system; limestone coping work, marble and granite water table work, interior plaster restoration and chemical grout injection work.

PS 100Q is a four story school building constructed in 1930.  The project involved assessing the cause of water infiltration and the cause of various deteriorated exterior masonry conditions. 

The resulting $3.2M project involved an extensive masonry restoration project including ornamental terracotta replacement; glazed brick flat jack arch replacement, parapet and building conrner reconstruction, steel lintel replacement and other selective masonry work.

PS32X is an existing 1899 school, five stories with a cellar and approximately 82,000 SF.  The project involved evaluating the condition of severe flooding and assessment of a failing structural clay tile floor assembly.  The resulting $18M project included site drainage improvements, reconstruction of the first floor/ceiling assembly, reconstruction of a new cafeteria, kitchen, toilet rooms, and a complete boiler replacement and various MEP system upgrades.  A temporary kitchen with toilet facilities was also provided in the play yard area as part of the phasing work of the project.

PS48Q is an existing 1936, three story building with a cellar.  The project involved evaluating groundwater levels and to provide a design for the control of water infiltration in the cellar.  The resulting $2.2M project involved developing a sheet mbmbrane type waterproofing system with a concrete topping slab to resist hydrostatic pressure; and a pressure injected resin type waterproofing system.  Also part of the design was the installation of pressure reliefs to provide additional protection against a temporary rise in groundwater levels.

Jamaica Learning Center was built in 1895.  This $6.5M project involved the repair of heavy timber wood trusses, complete roof replacement, extensive masonry restoration including restoration of brick corbeling, restoration of the auditorium including replacement of original stamped copper panels, site work including fence and sidewalk replacement work.  The project also involved a building wide electrical upgrade.

The existing 4-story, 75,000 SF building was renovated to provide 'function programmatic accessibility,' that resulted in a $4.5M renovation project.  The project included a building addition to house the new elevator, and reconstruction of an existing one-story entrance vestibule.  A temporary egress corridor was constructed to allow for continued occupancy.  Accessible toilets, door hardware and classroom sinks were provided throughout the building.

This project involved renovating an existing dated library into a state of the art multimedia center.  A dynamic ceiling is used to compliment the variety of functional seating areas.

This school was constructed circa 1970's, during which there was a stop in construction for a few years.  The project involved evaluating the reasons for the chronic deterioration of the existing stairs.  The resulting $1.2M project involved complete replacement of four stairs and the selective repair of two stairs.

The existing 600 seat auditorium was completely renovated.  Since the existing geometry and low ceiling were causing distinct echoes, a major component of this project was to improve the audibility of the space.  The ceiling was modified to provide volume to the space and acoustical treatment was provided on the vertical surfaces.  The $1.5M renovation included replacement of the existing seating, finishes and improvement tot he house lighting system and the repair of the stage rigging system.
