Sylvan Remediation Plan Addendum 6/19/13

On behalf of the University of Massachusetts (UMass), this addendum has been prepared by Woodard & Curran to document the characterization and remediation of Polychlorinated Biphenyl (PCB) containing caulking masonry joints to be disturbed as part of interior renovations at the McNamara and Cashin buildings located within the Sylvan Residential Complex at 112 Eastman Lane on the UMass Amherst campus in Amherst, Massachusetts.

This addendum is intended to be incorporated into the existing PCB remediation plans submitted for both the McNamara and Cashin buildings within the overall Sylvan Residential Complex, as described in the March 15, 2013 submittal.

This submittal includes a description of the materials identified, a summary of the remedial approach (waste segregation and in-place management approach consistent with the previously submitted plans for the Americans with Disability Act [ADA] restroom upgrades conducted at the Brown and McNamara buildings submitted in 2011 and 2012), the proposed verification sampling strategy, and a schedule for completing the work.

Project Summary

The scope of work to be conducted at each of the two buildings is as follows:

Cashin Building 

Interior renovations are planned to be conducted on the first floor as part of a reconfiguration of interior spaces for administrative offices in the Cashin Building. As part of the renovation, brick walls and a CMU block wall are scheduled for removal to allow for the construction of a new service desk window and overnight mail slot. In addition, an existing kitchen area, currently enclosed by the CMU block wall scheduled for removal, is being removed (the kitchen is not being replaced).

McNamara Building 

Interior renovations are planned to be conducted in the basement level as part of a reconfiguration of a common study room area. The renovations include the removal of two CMU block walls and six doors (including frames), as well as the cleaning and painting of seven door frames (including four doors located along the structural concrete).
