Torre Banco Macro, Argentina

The design of modern architecture confronts construction with very sophisticated demands.
The Torre Banco Macro is the new company headquarters of the Argentinian bank of the same name.
MULTIPROP shoring towers up to 16 m high were used to provide the form-giving load-bearing system for the reinforced concrete edge beams.
The edge beam construction for the tower finish placed very high requirements on construction operations.
The ovate ground plan of the high-rise building develops into an elegantly curved roof landscape more than 100 m high.

Project data

Location: Buenos Aires, Argentina

  • 135 meter high-rise office building in the center of Buenos Aires

Star architect César Pelli gave the skyscraper a distinctive finish with an elegantly curved roof landscape.

Requirements

  • The outer edges of the longitudinal sides merge from a convex into a concave form in the upper quarter
  • 1,300 m² large standard floors
  • 3.90 m high core walls in fair-faced concrete quality
  • Three-dimensionally warped reinforced concrete edge beam of the upper floor at a height of 135 meters

Customer's benefit

  • Project-specific, customized formwork and shoring solutions which fulfil all requirements and at the same time optimize the work performance.
  • Fast cycle sequences due to slabs and edge tables which are individually adjusted to the ovate ground plan, put together from four different radii.
  • Precisely defined required material quantities for slabs and walls ensure efficient work processes with economical use of material

In particular, the upper part of the tower with its distinctive geometry and the varying inclinations as well as the load transfer to different assembly levels presented substantial challenges. The PERI solution adapted itself perfectly to suit the given requirements and allowed us to optimize the work performance. I would like to especially highlight the engineering performance of PERI – through their support and the constant exchange of ideas with our site management, we could work out the best solution.

PERI solution

  • Customized slab table solution for the creation of the 1,300 m² big standard floors
  • 42 rectangular and trapezoid slab and edge tables, individually adjusted to the ovate ground plan which is composed of four different radii.
  • Forming of the 3.90-meter high core walls with PERI solution based on the VARIO GT 24 girder wall formwork system in fair-faced concrete quality
  • Shoring towers with four or multiple legs made of MULTIPROP aluminum props connected to MRK frames, in different heights ranging from 5 meters up to 16 meters
