Domino Sugar Refinery Bulkhead/Waterfront Platform Reconstruction

Domino Sugar Construction 2016-06-03 (2).JPG
Project Overview: 
The former historic Domino Sugar Refinery site is being redeveloped into several high-rise buildings for both residential and commercial space as well as the addition of five (5) acres of green open space. The existing gantry cranes, syrup silos and refinery building will be rehabilitated and integrated into the overall program in order to preserve the historical industrial heritage of the Williamsburg community.
McLaren's Role: 
Upon review and analysis, it was determined that the demolition and reconstruction of the entire platform was required but sections of the existing bulkhead could be repaired. McLaren used the foundation of the existing bulkhead, that sits on-top of the existing seawall foundation, saving the client a 1/3 of the cost. The new platform designed by McLaren will support a future public park that will be incorporated into the planned upland development. Upon completion of the inspection Phases, McLaren performed a detailed assessment of the current conditions as it relates to the future construction. Design alternatives were studied in order to provide all information for the reconstruction of the entire bulkhead as opposed to rehabilitation.

NYSOGS 95 Walsh Retaining Wall

NYSOGS 95 Walsh (2).jpg
Project Overview: 
On March 11, 2015 a slope failure occurred that impacted a senior living building located at 95 Walsh Road causing the evacuation of the building. McLaren responded immediately that evening to observe the retaining wall and slope failure, which exposed a portion of the croton aqueduct built in the 1830’s.
McLaren's Role: 
McLaren determined the resulting slope failure was predominately mud, and excess water behind the wall appeared to have caused the failure. The main challenge was to not further destabilize the slope while stabilizing the remaining walls. McLaren recommended several next steps to the client. The ensuing effort, under an Executive Order from the Governor of NYS, was to design and construct a new 320 foot long tied back soldier pile wall with concrete form lined lagging in front of the existing stone gravity retaining wall as part of a Design-Build contract with Moretrench.

470 Kent Avenue Echoscope Survey

470 Kent Avenue Echoscope Survey.jpg
Project Overview: 
Due to a collapsed portion of Bulkhead, McLaren was hired to perform an Echoscope Survey for the purpose of determining collapsed portions of the structure, outfall locations, pile locations and debris fields outboard of the structure.
McLaren's Role: 
McLaren prepared the Echoscope including attaching and calibrating equipment through the provision of a field survey crew. McLaren collected data along the 800 foot bulkhead. Survey data was collected in the NAD 83 horizontal coordinate system and NAVD 88 Vertical datum. Final reports, underwater images and videos were provided to the client. Specific results from the survey were utilized to quantify offshore debris, chart water depths and detail the issues with the bulkhead.
