Caunton Engineering have been employed at Kettering General Hospital to help build the new Cardiac Catheterisation Unit. They are working for Medicinq Ltd., the Procure 21 NHS-framework contractor – in actuality a team of four major contractors. Simons Construction is the lead contractor for Medicinq in this case.
The project involved building over the “air rights“of an existing single storey hospital building. Caunton erected a sequence of two storey portal frames (one pitched) over this building. These required massive 914x419 Universal Beam sections for the 20-metre-spanning floor beams.
The site was extremely difficult to access. A 250te mobile crane was necessary to erect both steelwork and pre-cast concrete floor planks, from outside the footprint of the building.
Fire engineering benefited the design of the frame – the floor beams were sprayed off-site with intumescent paint, while the columns were in fact boarded.
Resistance to vibration is so important in such sensitive areas. The area where the sensitive cardiac catheterisation equipment is housed required substantial floor stiffening thereby minimising induced vibration. This was a requirement that steel was readily able to accommodate.
