South Walkway, 2011

The project focus was to improve the overall aesthetics of the walkway since it is the main path for visitors into the campus.  To achieve this goal the walkway was realigned to provide screening of buildings on the south side and provide a smoother transition west of Tierney Hall, replace several retaining walls, steps at Hughes Avenue, and improve pavements, curbs and fencing as necessary for the length of the project.  Our services included design, construction documents, permitting, construction administration and inspection.

The project encompassed dredging and park improvements at four ponds including Loft’s Pond, Silver Lake, Tanglewood Pond and Mill Pond.  The project objective was to balance the need for public access, passive recreation, and the preservation or enhancement of water quality, fish and wildlife habitat and restore the ponds that have been impaired due to storm water runoff and bank erosion and address the declining aesthetic condition of the parks.  Construction included new pedestrian walkways and bridges, landscaping, lighting, grading of existing areas, drainage, installation of park benches, trash receptacles, fishing piers, gazebos, hydraulic dredging, bulkheading/erosion control, wetland planting, and installation of aeration systems.  Our services included topo, utility and hydrographic surveys, watershed base map research, Environmental and Engineering Study and Report, storm runoff calculations, preparation of hydraulic profiles, sampling and testing of pond sediments, review of pond biology, DEC Permits, met with local Civic Associations, construction documents, submittal review, respond to RFI's, and project management.  The improvements were made to the satisfaction of Nassau County Department of Recreation and Parks, Nassau County Department of Public Works, New York State Department of Environmental Conservation (DEC), and United States Environmental Protection Agency (EPA). The construction cost was $4,500,000.

The Goldstein Wing of Montefiore Hospital in New Rochelle underwent renovations to the ground floor and first, second and third floors. In support of this effort de Bruin designed access to meet existing and new entrances into the building. Construction included reconstructing steps to create a wider entrance and provide a new ADA ramp. This work required the reconstruction of a section of the public sidewalk which resulted in some grades in excess of 10%.and a new ADA pedestrian ramp from the street curb. An existing stepped terrace was renovated with blue stone treads, porous concrete pavers and bench seating to create a public space. de Bruin also provided routing of new underground electrical service to a new pad mounted transformer and designed footings for a new Montefiore sign. 

The project consisted of approximately 1,300' of road where the intersection of Warner Avenue and Lincoln Avenue meet the entrance to the Roslyn Station parking field of the Long Island Railroad.  The project was later expanded to include the intersection of Lincoln Avenue and Roslyn Road.  The project objective was to improve traffic flow and safety by clarifying traffic patterns at this complex intersection while taking into account the high degree of pedestrian traffic, railroad crossing, four bus stops, and close proximity of the local high school. Construction included turning lanes, road re-alignment, full pavement reconstruction, sidewalks, curbs, driveway aprons, rehabilitation of a passive sitting area, private property restoration to accommodate small grade changes, and relocation of sewer force main.  The overall construction cost was $1,500,000. Our responsibilities included topo and utility surveys, design, construction documents, conduct public information meetings, right of way mapping, property acquisitions, coordination with the LIRR and major utilities, construction management and inspection. 

The project spanned two miles of road through the Incorporated Village of Lynbrook.  The project objective was to provide a clear identity for the central business district and improve the aesthetics of the adjacent area with a street lighting system upgrade. Construction included lighting, new sidewalks and landscaping.  Our services included construction documents, permitting, bid assistance, respond to RFI's, run project meetings, process contractor payments, work with merchants to ensure continuous operation of their businesses, and construction inspection. The construction cost was $3,200,000.  

The existing site included two 5'x12' cast-in-place culverts constructed under the LIRR and Sunrise Highway and terminating on the north side of the railroad.  The hydraulic capacities of these two culverts were found to be just adequate for the Milburn system when a detention basin was proposed on the Brookside Preserve property.  Without the detention basin they are slightly undersized, plus the County demolished the culvert 100’ north of the LIRR further restricting this system.  The project objective was to increase the hydraulic capacity in order to reduce flooding in the area adjacent to the Brookside Preserve.  Construction included repairs to the existing culverts and construction of two 5'x12' cast-in-place culverts connected to the existing culverts.  The construction cost was $870,000.  Our services included survey, construction documents, construction management and construction inspection.
