Safe, fast and efficient
slab forming with PERI SKYDECK
When completed in July 2005 the new 4 storey Medical Research Centre building for Edinburgh University will be linked into the new Edinburgh Royal Infirmary.
A range of PERI formwork and falsework systems are being used by Balfour Beatty Construction Ltd. to construct the concrete frame forming part of this £34million project.
The concrete frame presented a number of technical challenges as the basement area of 5,000m² was completely enclosed and 4.80m deep. The three floors above basement level, each 5,000m² in area, then changed to a height of 3.90m. Approximately 15,000m³ of structural concrete and 2,000 tonnes of re-bar were used during the works.

Dougie Hanley, Construction Manager:
“The SKYDECK slab formwork system is without doubt the safest system I have used in years. It ensured that we carried out all our decking operations in a very safe and professional manner. Its simplicity on handling and early strike features contributed to this successful project.”
PERI MULTIPROP
These lightweight props are made of aluminium and can be combined with frames and used as tables or shoring towers. The MULTIPROP system is economically adaptable to any supporting situation. The frames can be fixed to the outer and inner tubes with the captive wedge.
|
 |
To overcome the constraints of the confined basement, PERI’s solution was to combine SKYDECK with small sections of MULTIPROP to accommodate the downstand beams. This same technique was then reused above with 3.75m SLT edge beams and SKYDECK platforms. |
|
Columns were cast using TRIO formwork with integral access ladders and concrete platforms which began as 5.40m high units and were then modified to 3.90m. All walls also used TRIO with areas being split into 12m long pours. |
|
The TRIO columns with access ladders and concrete platforms enabled the contractor to keep to a strict work schedule and avoid having to build and move scaffold access towers from column to column. At the on-site safety committee meetings it was commented on how professional and safe the equipment looked and worked in practice. |
|
Soffits were easily constructed with SKYDECK on 4.80m high MULTIPROP using access towers and passing the lightweight formwork panels up from below. |
|
Only a short time into the contract there were more than 2,500 SKYDECK panels on site. Predicted ease of use was confirmed as most panels were erected and stripped by labourers, freeing up joiners to work on walls, infills and edges. |
|
With SKYDECK comprising relatively small modules, and being easy to erect, it was possible to form the walls by omitting only one or two SKYDECK panels. As soon as the wall forms were struck the remaining panels were infilled and reinforcing works could begin on the deck. |
|
Elsewhere, PERI RUNDFLEX Panels were used on oval walls on the Rotunda lecture area with SKYDECK used to form edge beams and downstands for cooling towers on level 4.14m high MULTIPROP towers with SKYDECK panels and beams were also used on level 4 at external stair locations enabling cantilevered roof slabs to be cast. |
