Statement of Work

Objective

This project requirement is to replace the sash windows at the Courthouse, located in Yosemite Valley. The windows have begun to fail to operate and are in need of replacement for a means or egress and greater energy efficiency. The window frames will remain and the window sashes will be replaced to ensure operability.

Background

The Yosemite Valley Magistrate Court building is a modular building that was placed at the site in 1985. The windows are original to the building construction. They will be replaced through this project with the double hung sashes specified below. There will be an additional option for the replacement of the fixed windows.

Scope

This project consists of the removal and replacement of 26 sash windows with double-hung windows at the Courthouse. The existing sashes will be removed, leaving the existing window frames in place. A standard Z-Bar will be installed to hold the new window sashes in place.
