A low‐cost maintenance approach to high‐rise flats

During the 1960s, thousands of high‐ and medium‐rise single sided corridor blocks were designed and constructed using prefabricated concrete cladding systems. Most were characterised by inferior quality material and poor workmanship, poor supervision and inadequate environmental services which subsequently deteriorated to a state of disrepair. The main culprits were condensation, water ingress and cold bridging effects owing to low energy efficiency standards and lack of thermal insulation. It was initially contemplated that at the end of their life span these problems would be remedied by adopting “high‐tech” components involving composite cladding methods and highly automated environmental services to improve the operational efficiency and optimise their long‐term durability and life cost cycle. However, the cost has proved to be beyond client affordability. Meeting the requirements of today’s users and the current building regulations necessitated rethinking of the whole process; and alternative cost‐effective maintenance and energy efficient approaches had to be developed. This paper critically evaluates the approach to low‐cost maintenance and refurbishment of high‐rise buildings in parts of Birmingham, UK.
