iFLY Indoor Skydiving

Tigard, OR

Technical Information Project Completion Date: November 1, 2015 Project Location: Tigard, OR Size of Project: This 4 story tall indoor skydiving facility consists of 1,283 Cubic yards of concrete (20,425 Square feet of concrete total and 8,500 square feet of concrete for metal decks)

Strength Requirements: 4,000 and 6,000 psi

Water/Cement Ratios: 0.38 and 0.47

Unique or High Volume Admixtures: Seismic design parameters resulted in complicated details at the corners, where 7,000 psi poured in place concrete infills were used to tie together the interlocking grid of rebar extending from the precast panels.

iFLY Portland is a compact and complicated multifaceted structure allowing individuals to have an experience of sky diving while safely

being indoors in a wind chamber.

iFLY Indoor Skydiving

Integration of cast in place concrete, structural steel, and precast concrete has made a one of a kind product to add to the iFLY portfolio. A below grade basement

housing utilities and acting as a wind chamber was constructed with a concrete mat slab and 14” thick concrete walls.

This basement substructure was also the base for the 4 story structure and large Precast ram air tunnel.

The twin precast silos providing air flow to the sky diving chamber each consisted of 4 sides of structural precast panels, stacked 6 tiers and 80 plus

feet into the air.

The geometry of the silos, with sides sloping in as the structure rises, required careful construction sequencing to comply with the

engineered bracing.

interlocking grid of rebar extending from the precast panels.

In addition to the corner infills, 100s of NMB grout sleeves were used to tie the lifts of precast together. Extensive planning and careful coordination of the reinforcing steel details

was required to ensure a constructible design and maximize construction efficiency.

The interior lobby uses polished concrete to accent the many concrete features within the building. The 8500 SF of concrete metal decks are used for viewing areas, classrooms, and offices. You can’t miss this unique concrete structure

looming adjacent to Highway 217 near the Greenburg Road exit.
