Masonry Restoration and Cleaning

A. Summary

This section contains general design criteria for masonry restoration and cleaning and should be adhered to when providing quotes for cleaning.

B. System Design and Performance Requirements

When undertaking masonry restoration and cleaning, use extreme care to renew and extend the life of these buildings. Specify the minimum possible treatment necessary to attain a clean masonry surface.

This bid schedule enables adjustments, based on quantity, to fairly compensate for increases or decreases in the scope of work. The owner, architect, and contractor must document and agree on the final scope of work.

E. Restoration and Cleaning Guidelines
