Project data

Location: West Coast Peninsula, South Africa

  • Construction of 12 gigantic underground tanks for storing 13.2 million barrels of crude oil
  • 110 m x 110 m storage tanks with large-sized slab areas at a height of 17 m
  • Construction of diverse administration and logistic buildings


  • Execution of the 110 m x 110 m storage tank slabs at heights of 17 m
  • Execution of 2,400 columns with 8 m spacings and without the possibility of laying down the formwork
  • Realisation of the tank walls without any budget overrun
  • Cost-effective execution of the huge project without any serious delays


WBHO Construction (Pty) Ltd, Johannesburg, South Africa

Customer's benefit

  • Reduced cost and time requirements for the execution of the tank slabs and support columns through a project-specific implementation solution
  • Minimised problem factor for the execution of the high columns
  • Drastically reduced crane requirements and associated costs as the columns could remain in the tank for cleaning and oiling
  • Enormous cost savings due to the rentability of the TRIO Panel Formwork
  • Reduction in the number of errors and optimised work processes through an optimal overview and constant availability of all relevant information
  • Continuously optimised workflows and permanent point of contact through ongoing PERI project support

Contracts Director

"We wanted a partner on-board early in the project with whom we could work together on the solution. With PERI and the VARIOKIT system, we certainly made the right choice. It's definitely the best system, and I cannot imagine that we could have done it better or quicker with any other system."

PERI solution

  • VARIOKIT formwork carriage solution borrowed from the bridge building sector for cost-effective construction of the tank slabs
  • Development, testing and optimisation of reinforced, 17 m high circular column formwork which could be cleaned and oiled while still in a vertical position
  • Development of a concept for the economical execution of the large tank walls by means of project-specifically adapted TRIO Panel Formwork elements
  • Implementation of BIM for optimising the work and logistical processes during the planning phase and on the jobsite
  • Continuous project support provided by PERI project coordinators and supervisor
