About this file

Written by GovTribe AI ·

This document appears to be a collection of Asbestos Analysis of Bulk Materials test reports prepared by EMSL Analytical, Inc. for a federal contract opportunity related to EHRM Infrastructure Upgrades - Tier 2 in Prescott, AZ. The reports provide detailed analysis of various building materials sampled from multiple buildings, including Buildings 14, 151, 161, 70, 164, T6, 117, 160, and 154. The analysis indicates the presence and concentrations of asbestos and other non-asbestos materials in the samples. While this document does not directly address the required products or services for the federal contract opportunity, the asbestos analysis information may be relevant to the contract requirements or site preparation activities.
