Mega Bridge, Industrial Ring Road

Mega Bridge, Industrial Ring Road, Bangkok, Thailand - The four pylons of spectacular Mega Bridge in Bangkok rise 173 m into the sky. For the realization, the ACS climbing system ensured rapid construction process.
Mega Bridge, Industrial Ring Road, Bangkok, Thailand - The PERI formwork solution with the ACS self-climbing system and VARIO GT 24 wall formwork allowed efficient construction of the demanding pylon geometry with complicated three-dimensional intersections due to forward and reverse inclinations as well as tapering cross-sections along with chamfered edges.
Mega Bridge, Industrial Ring Road, Bangkok, Thailand - The pylons were divided into 3 sections with complicated transition areas. The continuously adjustable brackets of the ACS V climbing system ensured horizontally-positioned platforms at all times for safe and ergonomic working operations.

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
