New Haven Station Rehabilitation Project
Westchester County, NY

ECI conducted Hazardous Materials Surveys, including lead-based paint (LBP) and asbestos, at six rail stations in Westchester County. The stations, located along the New Haven Line, were evaluated prior to major renovations aimed at improving commuter access.

The work scope included reviewing construction plans and historic LBP surveys, preparing a work plan for the LBP inspections and complete asbestos inspections of all structures proposed for rehabilitation. The LBP survey was performed using a portable x-ray fluorescence device. During the asbestos inspection, potential asbestos containing material (ACM) samples were collected for analysis by a New York State-accredited laboratory. LBP was found on walls, billboards and structural (support) members, as well as railings. Asbestos, when present, was typically found in roofing materials.

During the course of the inspections, ECI's work scope was expanded several times to encompass additional structures and to conduct an environmental evaluation of geotechnical soil borings. ECI field screened the fill and soil samples with a photoionization detector and monitored for explosive gases.

Based on the inspections and reviewed data, ECI prepared LBP and ACM abatement cost estimates, plans, specifications and AUTOCADD 14 ® drawings in accordance with Metro-North standard practices.
