The Edge, Residential Structure, West Palm Beach, Florida
Perfect PERI Slab Table Solution
20 Units Moved in Only 2 Hours
The Edge, is a residential structure located in downtown West Palm Beach comprising two 16 story, 164 ft (50 m) high towers with an adjoining five-level parking facility.
With the west tower and large parking structure currently under construction, PERI engineers are working closely with Pate Construction on developing an efficient slab formwork solution for this project.
Detailed table flying sequences have been developed for all of the 174 tables on site. Specific tables were also designed to break apart to accomodate the retreating slab on higher levels.
With a quick release mechanism, the swivel head folds props out of the way to easily negotiate obstacles. The props then lock back into place when raised by the lifting hook allowing quick landing.
Combining UNIPORTAL formwork technology with PERI engineering has allowed Pate Construction to achieve high productivity levels on this project.

“This is my first experience with the UNIPORTAL tables. PERI engineers worked closely with our people to create an exact table flying schedule for every floor. As a result, we moved and landed 21 tables in two hours. We are really making money on our decks.”

With a repetitive floor plan and large open-faced facades, the PERI tableform was chosen as the most cost-effective solution for the slabs. The table head allows the props to quickly pivot during transportation and to automatically lock into position when being raised by the crane. |
|
Several PERI table striking and transportation trolleys are used to quickly move the tables to the slab edge where the PERI lifting fork safely raises them to the next working level. PERI engineers prepared detailed table flying sequences to make this process more efficient. Productivity rates of flying and setting over 20 tables in less than 2 hours were then possible, allowing the client meet the tight schedule. |
|
The use of lightweight PERI MULTIPROP aluminium post shores as well as PEP 20 and PEP 30 steel tube props ensure that the loads from both the tower and parking structure decks are safely transferred. |

There are a total of 174 tables used concurrently on this site, with 95 on the West Tower and 79 on the parking structure. The tables range in size from 6 m² to 50 m² and have been designed by PERI to be used throughout the entire life of the project. This posed a unique challenge regarding the slab retreats on upper levels, and the tables have been designed to accommodate this change. An entire row of tables was removed at one point, allowing the tables at the edge to efficiently slide back and shore the new floor plan dimensions. One table was designed to be separated into two halves for this reason. |

The robust steel panel formwork system, PERI TRIO, has been used throughout the site for all shear walls because of its versatility and quick shuttering times. The special TRIO columns panels are also being used due to their easy transportation, one piece clamp-on chamfer strip, and quick adjustability. The TRIO BFD, the one piece multi-purpose coupler, is used for all connections on both columns and walls, and can easily handle necessary timber fillers. The pre-assembled PERI FB 180 platform is used as a quick and simple working platform for accessing, aligning and supporting the TRIO wall forms on external shear walls. |

The site crew, headed by superintendent Gary Coultas has over 5 years experience with PERI systems but had never used the UNIPORTAL system before this project. With support from PERI Orlando, they are currently maintaining a concurrent 9 day cycle on the tower and a 15 day cycle on the garage, and comfortably meeting their construction schedule. The residents of The Edge West are to move in their new homes in May of 2007. |
