Having already successfully completed the first two phases of the Alice Lane Precinct, WBHO was appointed as the main contractor for the next phase of this prestigious project. Intelligent and strategic planning allowed WBHO to select a system that would alleviate the crane time required for construction of critical-path elements on the project.
PERI Formwork Scaffolding Engineering (Pty) Ltd South Africa was awarded the contract for the supply of formwork, and used the RCS hydraulic self-climbing platforms on the lift core structures. The lift core structures posed some special challenges, which included: changing door opening levels and locations, varying pour heights and changes in shaft geometry, which varied from closed boxed sections, to open U-section scenic lift arrangements.
To accommodate these challenges, PERI’s design and projects teams engineered the following processes:
To ensure minimal disruption to the project’s daytime activities, the system was completely installed and commissioned during night shifts. Efficient planning also ensured that the limited space available for laydown and assembly of the RCS system was optimised most effectively. PERI’s team of construction specialists in their respective fields provided day and night support to all aspects of the project: design, planning, programming, installation, supervision and so on. This ensured the successful installation and commissioning of the RCS system.
PERI systems purchased include:
The system placed on site has been a huge success allowing WBHO to achieve cycle times of as little as 6 days with a team of only 12 people on both shaft core structures. All challenges have all been met with success, and it stands to reason that with PERI’s expertise and quality of material, WBHO has been suitably impressed with the RCS system.
