- Suppliers' detailed drawings of support/connection types, marked up to show loads or
load ranges shall be used to facilitate type designations.
- Referenced construction details, from "Guidelines" mentioned in .01 above, of
support/connection types, marked up to show loads or load ranges may be used to
facilitate type designations.
12. Provide equipment restraints as manufactured by Mason Industries Inc. or approved equal.
Shop drawings must clearly indicate recommended method of installation and points of
attachment of hangers and supports to provide the necessary seismic restraint and be sealed by a
B.C. registered Professional Engineer.
- Shop drawings shall include statements detailing:
●
●
●
●
Operating weight
Calculated lateral force value V p
Number of foundation bolts required and shear force on bolts.
Tension force on anchorages from sum of moments for overturning.
- It is equipment manufacturer's responsibility to design strength and anchorage of internal
components that exceeds the force level required to restrain and anchor the unit to the
supporting structure. Manufacturer's equipment shop drawings, required to be submitted
for review prior to fabrication, shall certify that equipment construction complies with
requirements of 2006 B.C. Building Code section 4.1.9.

vendor. Equipment suppliers shall provide appropriate holes, tabs, brackets, etc. to
accommodate attachment of seismic restraint devices.
14. For Fort Nelson, B.C. site the following values apply:
Seismic Hazard Level (SHL) = C
Lateral force, V p = v(S p )W p .
Zonal velocity ratio, v = 0.05
Horizontal force factor, S p as defined in the Code for mechanical/electrical equipment.
W p is weight of component(s) being considered.
15. Provide the services of the Professional Engineer(s) who designed the restraint systems for
"Field Review" of the installed components including completion of the Letters of Assurance of
Professional Review and Compliance in accordance with the Building Code. Typewritten
