IHBC CPD ‘Boost AND checkup’: DBW on Prefabrication

buildingWith sources such as the IHBC’s Conservation Wiki re-posting from our membership journal – on post-war mass housing – Designing Buildings Wiki (DBW) has offered a briefing on ‘Prefabrication’ that IHBC members can both review as a ‘CPD boost’ and, where registered on DBW, enhance by shaping the article using their own skills, knowledge and experience.

The term ‘prefabrication’ describes assemblies that are manufactured under factory conditions and then transported to construction sites for incorporation into building or civil engineering works….

The acute shortage of housing following the second world war led to a boom in high-riseapartment blocks, and contractors turned to prefabricated panelised wall and floor system building in an attempt to meet demand. However, the jointing systems used and the failure to hide large joints produced a number of monotonous, ugly developments, often with condensation and other problems. Faults were so numerous that the Housing Defects Act 1984 created a scheme to compensate owners who had unwittingly purchased dwellings with defects. It was estimated that 31,000 owners were eligible under the scheme. See Housing Defects Act 1984 for more information…

.. The handling, transportation, craneage and erection costs of prefabrication have to be weighed against in-situ alternatives. Economic justification is often dependent on high volume and repetition. This has led to use in applications such as residential blocks, hotels and houses. Architectural success in disguising panel joints has improved public opinion, helping to combat the perception that prefabrication is ‘unsightly’ or ‘cheap’.
