The EFT-CRAFT Process

Development of a Unitized Roofing System

While the Original design of the architect (ASVD), was to install all roof & soffit cladding in situ, Craft, now EFT-Craft, offered an alternative proposed to prefabricate large-scale roof units at ground level. The largest of which was 42m long by 7m wide. Through this approach the following two key safety advantages where highlighted:

a. It eliminated the risks of having large workforce working at height as the bulk of the workers remained at ground level working in the safety of the fabrication jigs;

b. It enabled the installation to be completed by a small team of skilled rope access technicians. Depending on the size of the units to be installed the number of rope access technicians ranged from between 6-10, as opposed to needing 40 or more to install the units

utilizing a conventional in-situ buildup.

Simplification of the bolting connections

Our design team simplified the bolting connection design to the primary steel cleats at roof level which helped to minimize the use of workers requiring specialist rope access to  infill the strips between the roof units.

3D-scanning of as built cleats

Our surveying team was able to complete a thorough 3D-scan from ground level of all of the as built cleats, i.e. the supporting brackets receiving the prefabricated units. This was extremely helpful as the analysis of the scan identified potential installation issues and allowed the project team to make rectifications at ground level reducing the need for tricky alterations at height. The 3D scan proved to reduce safety risk and also saved time on the overall programme of works.

Note of interest

More than 5,000 cleats and 10,000 holes were 3D scanned from the ground!
