Suffern WWTP Upgrades

Suffern, New York

Project Overview

MFS Engineers & Surveyors provided geotechnical engineering services in support of the Suffern Wastewater Treatment Plant (WWTP) Upgrades project in the Village of Suffern, New York.

Suffern, New York

Project Details

MFS coordinated with our trusted drilling agency to drill six test borings at the project site during two subsurface investigations. The purpose of the test borings was to identify the general subsurface conditions at the project site to inform the project geotechnical and structural design components for the proposed floodwall construction. Each of the six borings were conducted on land along the alignment of the proposed floodwall. Each boring was conducted to depths between ranging from 12 feet to 38 feet below existing grade. MFS obtained samples continuously in the uppermost 12 feet and at five-foot intervals thereafter during each of the borings conducted.

MFS provided on-site, full-time special inspections during the subsurface field investigation. MFS observed the subsurface conditions and generated test boring logs to include soil classifications in accordance with the Unified Soil Classification System, 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 change. In addition, the logs showed total depth of penetration, blow counts, groundwater level, and types of sampling. The drilling equipment make and model, drilling method, date and time drilled, casing, any heaving conditions, loss of circulation, voids, or any other conditions observed during drilling will also be noted on the logs.

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 MFS’ geotechnical engineering recommendations were presented in a written geotechnical data report.

Following the subsurface investigation and geotechnical data report, MFS supported the design team by providing geotechnical and structural engineering design for the proposed sheet pile floodwall. MFS analyzed the earth and flood water loads on the proposed wall and provided design development and construction documents, technical specifications, and assisted the project team with design review meetings and coordination for the steel sheet pile floodwall.
