LIRR Jamaica Station Headquarters Structural Rehabilitation

LIRR Jamaica Station Headquarters Structural Rehabilitation .jpg
Project Overview: 
McLaren provided structural inspection, evaluation, and design services for the rehabilitation of exterior elements of the historic LIRR. Completed in 1913 with great fanfare, the Jamaica Station building’s restoration not only protects this valuable asset against further deterioration, but also highlights its historical and cultural significance. Since the building is eligible to be listed on the National Register, rehabilitation work was performed with the approval of the New York SHPO.
McLaren's Role: 
McLaren performed a detailed condition inspection of the Jamaica Station Building’s exterior, including all concrete, terra cotta, sheet metal, cast iron, brick, granite, and wood façade elements. In order to allow the building to maintain 100% functionality, a comprehensive staging plan was developed for the inspections. Accessing the facades was a key challenge; a specialized rigging contractor was utilized for these. Inspection findings were tabulated into a rehabilitation report. Following the inspection, McLaren began rehabilitation designs for the deteriorated structural elements. New lighting and coatings was also provided. Bid Phase Support was provided after construction documents were delivered.

Maryland Live! Divergent Diamond Intersection

Maryland Live DDI.JPG
Project Overview: 
McLaren designed the improvements to Maryland’s first Diverging Diamond Interchange (DDI). The MD 295 B-W Parkway and Arundel Mills Boulevard interchange was reconfigured into a DDI, to improve traffic flow and efficiency for the New Maryland Live! Casino.
McLaren's Role: 
Specific project tasks included the design of on-site and off-site roadway improvements including public off-site traffic/roadway improvements, preparation of schematic sketches, public roadway improvement plans, a formal permit submission package, and permit applications. The bridge and both roadway approaches were redesigned and reconstructed. The project also involved a field run topographic survey for all of the proposed public off-site traffic/roadway improvements to supplement the existing survey files; specifically at the improvement “tie-in” locations in accordance with Maryland’s Minimum Standards of Practice for Professional Land Surveyors. McLaren was also involved with the preparation of a schematic and final public stormwater management plans.

East Avenue Bridge Design

East Ave Bridge.jpg
Project Overview: 
The East Avenue Bridge is a single-span bridge supporting four main line railroad tracks, contiguous to the East Norwalk Train Station.
McLaren's Role: 
As Prime Consultant, McLaren was responsible for complete reconstruction design of the bridge including the replacement of the superstructure and replacement of the existing abutments for roadway widening. McLaren provided a preliminary engineering study of four (4) span/roadway width scenarios to minimize the depth of the structure in order to improve the vertical clearance beneath the bridge.

Survey & Engineering Services, Quaspeck Park Drainage Improvements

Quaspeck Park Drainage.jpg
Project Overview: 
McLaren was retained by the Town of Clarkstown to provide surveying and site civil engineering services because several streets and adjacent resident lots in Valley Cottage were experiencing problems with both surface and subsurface drainage. Project locations included Charles Boulevard, Helene Road, Quaspeck Boulevard, East Mary Lane, West Mary Lane, and Rock Drive. To correct these deficiencies, modifications and improvements to the existing storm drain system were required.
McLaren's Role: 
McLaren’s surveying services included a boundary and limited topographic survey of four (4) parcels of land for the creation of drainage easements in favor of the Town of Clarkstown. The limited topographic survey included all utilities in the above-mentioned predefined area. Trees with a diameter greater than 8” within this predefined were located and mapped. Off-site drainage structures leading from NYS RT. 9W to Rockland Lake were also e located and mapped for Civil Design purposes. McLaren’s site/civil engineering services associated with this drainage improvement project included a site investigation, environmental assessment, hydraulic analysis, drainage analysis, drainage design, public outreach and construction administration.
