Ayalon Motorway Bridge, Israel

The expert engineers of PERI Israel ideally matched the superstructure formwork and the shoring for the crossing of a highway over a railroad line.
The PERI formwork and shoring solution as well as the ongoing jobsite support accelerated the construction work for the 450-meter-long highway bridge (structure 301).
The large-size formwork units with about 8 m x 3 m, based on the VARIOKIT engineering construction kit, could be moved efficiently in only one crane lift.
It was possible to adjust the two modular-type systems PERI UP and VARIOKIT extremely flexibly to the bridge’s geometry and the loads.

Project data

Location: Ga'ash/Shefayim, Israel

The Ayalon highway (20) is the main arterial road in and around Tel Aviv. It is expanded to the north, and close to Shefayim, in the direction towards Haifa, it joins the highway no. 2, which runs in parallel with the coast of the Mediterranean Sea. The construction of the 450 m bridge structure has become necessary to cross a railway line. 

Requirements

  • 450-meter-long, 12-bay bridge
  • 15.60-meter-wide superstructure in T-beam cross-section
  • Concreting of the whole bridge in only 4 cycles
  • Concreting cycle length: 115 m

Customer's benefit

  • Flexible adjustment of the two construction kit systems, PERI UP and VARIOKIT, to the bridge’s geometry
  • Ideal matching of superstructure formwork and shoring by PERI expert engineers
  • Fast construction progress due to fast assembly and fast cycle sequences as well as concreting of webs and panels in one pour
  • Moving of the 8 m x 3 m formwork units with only one crane lift

Building a bridge reveals many challenges along the way. PERI was the best partner for that matter, being focused on our requirements with innovative design and ideas, on-site support and excellent equipment: PERI UP as ‘stand-alone’ shoring and VARIOKIT as stiff formwork units.

PERI solution

  • VARIOKIT formwork units and supporting scaffold, based on the PERI UP Flex modular-type scaffolding system
  • Formwork units with the large dimensions of 8 m x 3 m
  • PERI UP Flex shoring solution with 1.50-meter-wide and 15.75-meter long shoring tower disks as well as load-optimized adjustment due to bay widths of 150 cm and 75 cm
  • Anchoring of large-size formwork units after the concreting and hardening process with DW 15 ties on the bridge superstructure to take load off the PERI UP shoring structure, for fast moving of the shoring structure into the next cycle
  • Lowering of the formwork units with winches without time-consuming dismantling, for fast transporting to the next construction section
