Formwork solution for the island´s large-scale infrastructure project

A mixed commercial, residential and leisure project is under construction on Saadiyat island located 500 m off Abu Dhabi. The island will feature many world class resorts, museums and universities. It is expected to be completed in 2020. MEVA KHK in Dubai were consulted to design and provide a comprehensive formwork solution for the island´s large-scale infrastructure projects.

Part of the project is the building of a new sewage treatment plant with biological tanks. The project encompasses the following concrete structures:

  • Main Storage Tanks
  • Biological Tanks
  • MBR Gallery
  • Equalization Tanks
  • Pre-Treatment Plant
  • Main Pumping Station
  • Workshop

MEVA KHK Solution

  • 3500 m² of Mammut 350 wall formwork
  • 6.6 m high CaroFalt column formwork for the construction of the main storage tanks
  • Custom-tailored rails designed and manufactured by MEVA KHK facilitate the change of thickness perimeter and dividing walls of the storage tanks (6.6 m high) and biological tanks (8.0 m high).
  • The 9.0 m perimeter walls stepped in on the external face from 900 mm at base to 400 mm at 3.5 m.
  • The dividing walls incline 250 mm at 3.5 m height to 4.0 m height on both sides.
  • The equalization tank walls, 9.0 m high and 80 cm thick, were poured to full height in one pour with 0 mm deflection.

The contractors were especially pleased with the stability and robustness of the formwork and the 0 mm deflection achieved on the high walls that were poured to full height in just a single pour.

Kharafi National LLC´s Senior Civil Engineer said that given the performance and service on this project, MEVA KHK will definitely be used on future projects!
