MAINTENANCE OF mechanical equipment
Provide guards, handrails, ladders, and platforms for maintenance to meet OSHA requirements.
See VA Design and Construction Procedures (formerly Construction Standards CD-54), VA Handbook H-18-8, and Uniform Building Code.
Provide seismic restraints for equipment where ‘Z’ value is equal or greater than 0.10. Comply with local code if there are more stringent requirements.
Provide seismic bracing of piping and ductwork where ‘Z’ value is equal or greater than 0.20. Comply with local code requirements if there are more stringent requirements.
Z values of various VA medical Centers are listed in VA Handbook H-18-8. Verify these values before proceeding on a specific project.
VA allows use of SMACNA or NUSIG details for seismic bracing.
