Dear Mr. Davies:

This is in response to your letter of April 11 to the Occupational Safety and Health Administration (OSHA) in which you request a clarification of the masonry wall bracing requirements contained in 29 CFR 1926.706(b).

As you recognize, the requirement to install bracing applies to all masonry walls over eight feet tall that are not otherwise adequately supported. This is the case whether the wall contains reinforcing steel (rebar) or not. It is the responsibility of the employer to assure that walls not adequately supported to withstand all normally expected forces, which would include prevailing wind pressure loads, building geometry, and wall location, are braced. If the employer determines the wall is capable of withstanding the forces applied during construction, then the wall would be considered to be adequately supported and would not require racing. The employer must be prepared to substantiate this determination.

If you require any further assistance, please do not hesitate to contact us again by writing to:
