Windows in Historical Buildings

James H. Quillen VA Medical Center, Mountain Home, TN


Scope: BES Design/Build, LLC (BES D/B) provided design and construction services for the removal and installation of 480 windows in historic buildings 19 and 39-47. This project consisted of ten historic structures that are listed on the Department of Interiors National Register. Coordination and approvals were required by the State Historical Preservation Office.

Buildings 19 and 39-47 were residential-style two-story structures that were over 100 years of age. Some were offices and some were temporary or permanent housing quarters. The existing windows on buildings 19 and 39-47 were old and in poor condition with infiltration issues.  The windows were original equipment, and were single-pane, predominately weighted sash. BES D/B removed the existing windows, and designed and installed new Energy Star compliant primed wood windows. The replacement windows are not only energy efficient, but also conform visually to the existing historical window style.

The work was performed in occupied facilities and included lead paint abatement, remediation and complete replacement of 480 windows. BES D/B furnished all labor, A/E designs, materials, supervision, and equipment necessary to complete the design and construction for this project. BES D/B also provided preliminary and final contract drawings, specifications, and construction period services.

BES D/B ensured a safe work environment for subcontractors and the VA Medical Center employees and patients while executing the tasks. The structures were inspected to evaluate any environmental concerns such as asbestos, lead, mold and presence and/or growth of pathogenic biological  agents for precautionary and regulatory compliance requirements. An X-ray fluorescence (XRF) spectrum analyzer was utilized to determine the lead in the paint on the window components. Bulk samples of the waste were collected to conduct toxicity characteristic leaching procedure (TCLP) for lead, to determine disposal requirements. An exposure assessment was performed during the removal of the windows by collecting working area and personal air samples for asbestos and lead.
