Mid- & High-Rise Structures» Decreases weight of structure •Reducesfoundationrequirements •Lessensseismicimpact» Reduces column footprint •Facilitatesspaceplanning •Produces2%moreuseablefloorspace» Provides flexibility •Allowsforcoredrillingwhereneeded •Offersoptionsforsuspendingcomponents •FinisheswithpaintedDekorgypsumceilings

Panelization» Creates vertically aligned lineal chase way for M/E/P» Creates flush spandrel beam condition

(Allowsfloor-to-ceilingglasscurtainwall)

Safety with Panelization»Assemblesatgradelevel» Carries welded wire fabric and rebar bundles

when lifted» Includes fall protection before lifting

Vertical Transportation of Panels» Needs fewer crane picks» Carries additional materials when lifted» Reduces burden on man lifts

Versa-Floor™ [HR] panels create aligned lineal chase ways, which simplify M/E/P installation.

Flush spandrel beam condition allows floor-to-ceiling glass curtain wall.

Versa-Floor™ [HR] creates unobstructed ceilings without filler beams.

Versa-Floor™ [HR] has no post-tension strands to hinder M/E/P installation.
