  • Customized girder trusses
  • GT24 Girder
  • MP Towers with MRK frames
  • Quickstage Shoring support
  • 4mm and12mm Plywood



The architect met with the PERI team two years prior to the project to discuss the project. Based on PERI's past success on similar projects, a formwork solution was found to be viable.

The intricate chapel roof is 20m long x 12m wide and 6m high at the top apex.
It was agreed that a 1:50 concrete demo "cup" was constructed in the PERI Cape Town yard. The project team was involved with the process and shotcrete was selected as the chosen product. The concrete demo proved invaluable in the planning of the project.

PERI was the only formwork supplier that was man-enough to price this project. From the  designing, 3-D formwork modeling, site support, technical know-how and overall service was excellent.

We will gladly partner with them again on future projects like these - it can be done.

PERI solution


PERI Cape Town provided on site support for all set-out points. PERI engineered the truss solution to keep the formwork as simple as possible. Using a combination of trusses and ribs, the structure was formed.

Using Autodesk inventer a total of # 584 x trusses were designed and then produced by a local roof truss manufacturer. All trusses was marked and checked for alignment before delivery to site.

Concrete finish required:
Smooth/shape of slab soffit and to be skimmed.

Sequence of formwork erection : 

  • Shoring towers complete with platforms were erected.
  • Set-out points and levels plumbed and checked. 
  • Trusses placed in position from below and from the top.
  • 38mm timber battens was fixed horizontally as temporary and falsework.
  • Shutterply was fixed in layers, 12mm + 4mm.
