Construction of Gwen Ifill (Railroad) Park

Queens, New York

Project Overview

MFS Consulting Engineers & Surveyor, DPC provided professional geotechnical engineering services for the New York City Department of Parks and Recreation (NYC Parks) Construction of Gwen Ifill (Railroad) Park project. The project consisted of construction of a new park at the project site. As part of the construction, a comfort station and sports lighting were constructed, in addition to on-site green infrastructure practices.

Project Details

Prior to mobilizing for the subsurface investigation on site, MFS coordinated with a subcontractor to provide clearing and grubbing services as necessary to facilitate access to each testing location. Following the clearing and grubbing services, MFS coordinated with a trusted subcontracted drilling agency to drill three (3) structural test borings to a depth of 100 feet below grade. MFS obtained samples continuously in the upper 12 feet and at five-foot intervals during the borings. An additional eight (8) green infrastructure test borings/permeability tests were conducted at the project site. The green infrastructure borings were completed to a depth of 15 feet below grade and the permeability tests were conducted at depths of 3 feet, 5 feet, and 10 feet below grade.

During the test boring operations, MFS observed the subsurface conditions and generated test boring logs to include soil classifications in accordance with the Unified Soil Classification System (USCS) and New York City Building Code (NYCBC), groundwater observations, action of equipment, and other noteworthy observations. The boring logs showed borehole and sample diameters and depths at which drilling or sampling methods or equipment changed. Logs showed total depth of penetration, blow counts, groundwater level (if encountered), and types of sampling. The drilling equipment make and model, drilling method, date and time drilled, casing, any heaving conditions, loss of circulation, and voids were also noted on the logs.

During the permeability tests, the MFS inspector recorded the drop in water at specified intervals to determine the permeability rates of the soils.

Laboratory tests were performed to classify soils and obtain geotechnical physical characteristics for soils. The results of the field investigation and laboratory testing program, evaluation of the subsurface conditions, and our geotechnical engineering recommendations were presented in a written geotechnical engineering report which included a seismic evaluation and design and construction recommendations for the proposed comfort station and sports lighting.
