Practical Notes

Use this code to accurately specify stone dressing finishes (e.g., ashlar, punched, tooled, or rock-faced) in a Bill of Quantities (BOQ) to prevent contractual disputes.

Highly useful for conservation architects and engineers when interpreting historical architectural restoration documents or legacy masonry specifications.
