Mega Bridge, Industrial Ring Road, Thailand

Project data

Location: Bangkok, Thailand

bridge connection as part of the Industrial Ring Road IRR over the Chao Phraya river, motorway junctions lie in the middle

  • construction: two cable-stayed bridges
  • length: 702 m and 582 m
  • height of the four pylons: 173 m and 164 m
  • span width: 326 m and 398 m
  • construction period: until 2006

Requirements

  • simultaneous construction of four pylons
  • sophisticated pylon geometry with complicated three-dimensional intersections  due to forward and reverse inclinations
  • inclining cross-section
  • chamfered inner and outer edges

Customer

TNNS Joint Venture:
Taisei, Nishimatsu, NKK, Sino Thai

Customer's benefit

  • concrete pouring in a weekly cycle
  • not a large amount of substructure work on the ground
  • high productivity due to safe and convenient work processes

The PERI formwork solution made a substantial contribution to the successful realisation of this project. The formwork adapted superbly to the changing cross-sections and different inclinations.  High work-rate was achieved as a result of the safe and convenient work processes provided by the PERI ACS self-climbing formwork.

PERI solution

  • crane-independent ACS self-climbing formwork
  • coordinated formwork and platform execution on all standard concreting steps
  • consideration of the cable outlets on the pylon heads
