25th Street Wharf Rehabilitation

25th Street Wharf, Brooklyn
Project Overview: 
As part of a waterfront contract with Lafarge North America, McLaren was selected to provide waterfront rehabilitation services at the 25th Street Wharf, located along the Gowanus Canal in Brooklyn. The site is the operational home for New York Sand and Stone, a heavy industrial facility. As part of the lease agreement, Lafarge requested McLaren’s services to ensure the quality and life span of the structure.
McLaren's Role: 
McLaren performed above water and underwater inspection of the wharf, which comprises a low-level relieving platform. The firm then provided preliminary and final design services with construction cost estimates for rehabilitation and life cycle cost analysis. Because the facility is an old, pile-supported structure, McLaren was exposed to and developed solutions for a range of conditions – in consideration of environmental regulations. Repairs included concrete encasement of deteriorated piles, replacement of failed timber members, and installation of a new timber fender system to accommodate large ship berthing. McLaren also provided permitting support and construction management services, including bid phase support.

Monroe Street Bridge Replacement Design

Monroe Street Bridge Replacement
Project Overview: 
The Monroe Street Bridge is a three-span overpass supporting four New Haven mainline tracks and two sidetracks, which service Metro-North Railroad’s Danbury Line. It is supported by stone masonry abutments and built-up steel piers supported by stone masonry pedestals. The primary objective was to replace the superstructure and piers and to improve the existing roadway vertical clearance.
McLaren's Role: 
McLaren was responsible for complete reconstruction design of the bridge, which was complex due to superstructure height limitation. The three-span structure was replaced with a single-span steel structure spanning approximately 72 feet. A finite element model of the entire superstructure was performed. Longitudinal stringers with moment connections were provided in addition to the thru-girders to share the loads. An elaborate construction staging scheme was performed to maintain three main tracks in operation at all times. Reconstruction was accomplished in multiple stages to minimize the impact on railroad traffic.

Signature Place

Rendering of the proposed high-rise at Signature Place
Project Overview: 
Signature Place is a proposed 38-story residential high-rise complex in downtown Stamford comprising 1.6 million square feet of floor area. Phase 1 of the project consisted of Building 1, a 38-story tower, plus 289,000 square feet below grade. Phase 2 included Buildings 2 and 3 - two 30-story towers plus 318,000 square feet below grade.
McLaren's Role: 
McLaren provided structural and foundation engineering for Signature Place. The structural system design is composed of conventionally reinforced concrete with shear walls. The use of high strength concrete (12,000 psi) was considered to diminish column sizes with increased leasable space. The foundation system design is a series of six foot diameter caissons that were to be drilled to quartzite bedrock. Groundwater management was a serious consideration for both constructability and serviceability, as the actual groundwater level is above the lowest floor level.

City Center Mall, Mixed-Use Retail and Residential Facilities

City Center Mall, White Plains, NY
Project Overview: 
The City Center Mall project is a mixed-use high-rise retail and residential facility at the former Macy's Department Store in downtown White Plains, New York. Three 35-story residential buildings were also designed at this location encompassing 727,900 square feet. A municipal parking garage was included providing both below and above grade parking, and a garage core encompassing 767,000 square feet.
McLaren's Role: 
McLaren provided foundation and structural design for retail areas, loading docks, and below-grade parking. Within the retail space are the White Plains Performing Arts Center and a multiplex cinema with an IMAX Theater. The PAC includes a 400-seat theater with stadium seating, overhead pipe grids and catwalks, and mezzanine for storage, lighting and lobby. McLaren was involved with design of sloped raker beams and light gage framing that supports stadium seating; reinforcement of existing steel framing to support new theater loads; structural support for box booms, lighting equipment, and other theater features; and coordination with architect and theater consultant on layout and structural requirements for theater features.

Marriott Inner Harbor Hotel and Convention Center

Marriott Inner Harbor Hotel, Baltimore
Project Overview: 
McLaren was chosen to provide engineering services for the Baltimore Marriott Inner Harbor Hotel and Convention Center. The Hotel was designed and constructed in two separate phases. The original phase consisted of a 12-story hotel tower and a one-story steel frame low-rise that housed the convention facilities. The second phase consisted of another 12-story hotel tower and a two-story concrete frame low-rise that housed additional convention facilities in both phases.
McLaren's Role: 
Phase I required long clear spans to accommodate large meeting rooms and banquet facilities. Phase II required a framed ballroom floor, which necessitated heavy post-tensioned concrete beams and floor slabs to accommodate impact loads produced by ballroom activities (dancing). In addition, Phase II employed the use of post-tensioned concrete transfer girders, which clear spanned the ballroom and supported the hotel tower above. Hotel towers for both Phases were constructed from post-tensioned concrete flat plates supported on reinforced concrete columns and shear walls. The lower levels (street level) are reinforced concrete flat plates.
