NYC Parks Weeping Beech Park Playground Reconstruction

Queens, New York

Project Overview

MFS Consulting Engineers & Surveyor, DPC provided subsurface investigation services for the City of New York Department of Parks and Recreation (NYC Parks) Weeping Beach Park Playground Reconstruction project. The investigation was part of a feasibility study for the design of stormwater management systems.

Project Details

MFS’s services included subsurface borings, geotechnical and environmental sampling, in-situ permeability testing, laboratory analysis, and associated reporting. The investigation consisted of five borings with associated permeability testing distributed across the project site.

MFS coordinated with a trusted subcontractor drilling agency to drill five test borings and permeability tests. Each of the borings were completed to a depth of 15 feet below existing site grade. MFS obtained Standard Penetration Test samples continuously in upper 15 feet during each boring. In addition, environmental samples were collected in the uppermost 6 feet below grade. Permeability tests were conducted at depths of 3 feet, 5 feet, and 10 feet below grade in an adjacent hole at each location.

During the test boring operations, MFS observed the subsurface conditions and generated test borings logs to include soil classifications in accordance with the United Soil Classification System (USCS) and New York City Building Code (NYCBC), groundwater observations, action of equipment, and other noteworthy observations. The boring logs showed boreholes 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 heavy conditions, loss of circulation, and voids were also noted on the logs.

Geotechnical laboratory tests were performed to classify soils and obtain geotechnical physical characteristics for soils. Environmental laboratory tests were conducted on the soil samples obtained and the results were compared to the New York State Department of Environmental Conservation (NYSDEC) Part 37 Restricted Residential Soil Clean Up Objectives. The results of the field investigation and laboratory testing program were presented in a written geotechnical scope summary memorandum.
