RMD's modular cantilever formwork system Paraslim has been used on two major roadwork schemes. It was adapted for the construction of bridge deck edges on the A30 Kennards House junction in Launceston, Cornwall being built by Tilbury Douglas. It is also in use on Costain Civil Engineering's A34 Newbury bypass in Berkshire.
RMD claims that Paraslim is half the cost of underslung or overslung systems because it uses substantially fewer components, and this is one of the reasons why the system was picked for the road projects. It is also said to be safe and rapid to erect.
At both Newbury and Launceston, use of Paraslim did away with the need for access beneath the soffit and allowed erection, levelling, tilt adjustment and stripping operations to carried out safely from deck level.
Paraslim is based on a triangular frame supported by a single diagonal tie. This tie is attached to a Paraslim bracket, unique to RMD, which is fixed to the top of the bridge beam.
