Construction
Interstitial deck installed after mains hung from floor above. Contractors typically used high-
reach lifts to install from structural floor below. Openings through platform were sleeved before
lightweight concrete placed.
Floor construction is topping slab over precast, pre-tensioned "joists." Contractor was allowed
to run conduits for branch circuits in topping. Creates difficulties for remodel work.
Smoke evacuation is provided for interstitial levels. Fire barriers do not extend vertically through
the service zone.
Operation
Interstitial service zone facilitates maintenance and modifications of service systems.
Modifications
Lightweight concrete easily cut (hole saw) and patched for service relocations.
Comments--Advantages/Disadvantages of VAHBS
What would you change?
Service bays should be sized for growth potential in the module.
Enforce rules for service distribution (i.e., no conduit in slabs).
