Geotechnical Report 8 of 8 A0004.pdf

This document is a Geotechnical Engineering Evaluation report containing laboratory test results for a Replace Boiler & Upgrade Controls Project at West Roxbury Veterans Administration Medical Center in West Roxbury, Massachusetts. The report, prepared by R.W. Gillespie & Associates, Inc., is dated December 16, 2021, and assigned Project No. 1821-001.

The document consists of nine Particle Size Distribution Reports presenting soil analysis data from multiple boring locations (B-1 through B-9) at varying depths. Each report includes graphical particle size distribution curves and detailed soil classification data, including grain size percentages, Atterberg limits coefficients, USCS classifications, and moisture content measurements. Sample locations range from depths of 20-22 feet to 10-12 feet, with soil descriptions varying from poorly graded gravel with silt and sand to well-graded sand with silt and gravel. Classification designations include GP-GM, SW-SM, GW-GM, and SP, all rated as A-1-a under the AASHTO system. Moisture content ranges from 4.3% to 20.0% across samples. The testing was conducted by R.W. Gillespie & Associates, Inc., located in Biddeford, Maine, with results checked and verified by laboratory personnel. This geotechnical data would support design and construction planning for the boiler replacement and controls upgrade project at the VA facility.
