Project data

Location: Los Angeles, United States

Two 46-story residential towers are now being constructed in the Century City section of Los Angeles alongside the Fairmont Century Plaza Hotel. Complementing the recently refurbished iconic crescent-shaped structure, the new glass towers will add approximately 300 elegant condominium homes to the area.

Requirements

The towers, which are being built at the same time, have hexagon-shaped cores. For each of the cores, the contractor is using a PERI ACS Core 400 self-climbing interior system with gantry beams suspending the exterior formwork.

The open tower lobbies are designed with structural steel framing, with no concrete slab from which the construction could proceed. A radius trolley trailer beam suspended from the core climber facilitates construction, enabling the contractor to set the lobby steel.

Customer

Largo Concrete, Inc., Tustin, CA

Customer's benefit

  • Featuring high-capacity single-stroke hydraulic cylinders, the ACS 400 system climbs to the next level in just 20 minutes. Because it uses fewer brackets, anchors, and other parts and pieces, labor requirements and cycle times are reduced even more.

  • Internal and external platforms for use with the ACS 400 typically are preassembled, increasing safety and reducing the crane time required for installation of external suspended platforms.

Tower Superintendent

The PERI ACS 400 is a very simple, smooth-running system, and the PERI field crews are great. Assembling the first six-sided climber was a challenge for all of us, but the second then went together quickly and easily. I’m very happy with how simple it is in use.

PERI solution

  • The floor slabs are being placed using PERI VARIODECK Steel Waler Slab Tables. Custom steel corners on the interior easily accommodate the nonstandard angles of the hexagonal core. In addition to their high load-bearing capacity, the VARIODECK tables can be moved quickly from one level to the next with a single crane lift.

  • Screens that work with PERI’s RCS Rail Climbing System enclose the upper floors as they are being constructed and provide enhanced safety on the site. Completion of the Century Plaza residential towers is expected in 2019.
