Block 30, Portland, Oregon
Forming Slabs using Efficient, Simple and
Effective SKYDECK System
The Willamette Riverfront area in Portland, Oregon will become a host to over 15 structures similar to the “Block 30” Condominium project. These twin towers will house mainly condominiums, with office and retail space located on the bottom floor. The 60,000 ft² (5,600 m²) floor plate of this project includes two buildings with approximately 11,000 ft² (1,000 m²) footprint per floor.
In order to achieve a six day pour cycle, Hoffman Construction elected to use the patented PERI SKYDECK slab formwork system for the floors and the TRIO Shaft system for the cores. The PERI SKYDECK system uses a drophead technology which allows the shores to stay in place during the stripping procedure. This saves in labor costs during the erection and dismantle stages and reduces equipment requirements as only the level being formed is required.

„Using the PERI SKYDECK system allowed my crew to achieve the six day pour cycle scheduled for this project. It was extremely easy to assemble and strip, due to the light weight components.”

Using a modular decking system on this project also allowed Hoffman Construction to eliminate the need for custom solutions for the cantilevered balcony design on this structure. Using standard components, PERI was able to provide the client with an effective design using a cantilevered SLT 375 mainbeam on the SKYDECK system, providing a safe and efficient work environment for any finish work required on the slab edge. |
