Manhattan, New York

Project Overview

Project Details

The project consisted of the construction of a new storehouse facility to support NYC Parks operations for the Borough of Manhattan within Randall’s Island Park.

MFS completed a topographic survey to identify visible above-ground features, including buildings, curbs, pavements, and utilities. Utility surveys were conducted to locate surface infrastructures such as manholes, catch basis, and utility poles. Subsurface utility lines were mapped based on surface features and available mapping data.

MFS coordinated with our trusted drilling agency to drill four test borings at the project site in accordance with adherence to NYC Building Code specifications. Each of the borings were completed to a depth of 25 to 40 feet below existing site grade. Samples were obtained continuously in the upper 12 feet and at five-foot intervals thereafter during each boring. In addition, MFS conducted five borings and infiltration testing in the footprints of the stormwater practice areas. Each of the five infiltration tests were conducted in borings in accordance with the procedures outlined in the New York City Department of Environmental Protection (NYCDEP) New York City Stormwater Manual and Appendix D of the New York State Department of Environmental Conservation (NYSDEC) Stormwater Management Design Manual (SWMDM). Each of the infiltration test borings were conducted to a maximum depth of 15 feet below grade and one infiltration test was conducted in an adjacent borehole. The infiltration tests were conducted at depths ranging from 8 to 11 feet below grade.

During the test boring operations, MFS observed the subsurface conditions and generate test boring logs to include soil classification in accordance with the Unified Soil Classification System (USCS), groundwater observations, action of equipment, and other noteworthy observations. Upon completing the field investigations, MFS assigned laboratory testing on select sample to verify field classifications and obtain geotechnical physical characteristics of the soils.

MFS’ site/civil team prepared a site plan package, which consisted of site data including key map, proposed use, zoning table, and other items in the plan requirements, a site demolition and removal plan that depicted the existing site conditions with the items/structures that need to be removed or to remain, a proposed site plan that depicted improvements including the new storehouse structure footprint, facility vehicle travel ways, pavement, signage, dimensioning of the site features to the property lines, and other site related elements. A grading plan was prepared to divert storm water away from buildings and around structures in a controlled manner to prevent property damage. A site utility plan was prepared to depict water, sanitary, gas, electric, IT, security and fire services from adjacent city and private owned utilities.
