Stained Glass Restoration
Use this CSI 3 part SimpleSpecs™ master specification to specify the restoration of historic stained glass windows, including glass and lead and zinc, came.
Restoration of window frames and sash are specified in several Division 08 sections and should be coordinated with this section.
Replacement of damaged historic glass should be carefully evaluated since some glasses can no longer be reproduced and salvaged glass may be difficult or impossible to locate. Some historic pigments can no longer be used due to environmental concerns, and some glass-making techniques have been lost over time. Therefore, it is often best to retain and repair glass containing only minor damage.
Acids and caustic and abrasive cleaners, including common household glass cleaners, should never be used on historic glass since damage to the glass or came could result. The painted glass should be carefully tested prior to cleaning and may require cleaning only with soft swabs and water.
In place, restoration should be limited to small, non-structural repairs only. Windows requiring major restoration, including the removal of bowing due to insufficient support structure, should be carefully removed for shop restoration on a flat surface.
For additional information on this subject, refer to Preservation Brief No. 33 – The Preservation and Repair of Historic Stained and Leaded Glass, National Park Service, www.nps.gov.

The SimpleSpecs™ master specs concept
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable. In fact, quite the opposite is true. Having shorter, easily understood specifications makes us less likely to have problems in the field.
A belief that having lots of words protects us from a Contactor making mistakes. There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit
SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.
Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.
Hidden Guide Text
Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.
SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually. Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
