East and North Hertfordshire NHS Trust
Description: As Principal Supply Chain Member constructor to Medicinq (ProCure 21 Principal Supply Chain Partner) we had early involvement with users, structural engineer and scaffolding specialist, which ensured that both planning and buildability issues were optimised in advance of construction activity. Tiling/render was made safe by fixing Corus metal sheeting clamped against the surface and tied back to the structure. Windows were replaced with steel reinforced pvc frames and double glazing appropriate to the level of exposure. The scaffold was removed floor by floor as work was completed. On-going liaison with users and infection control nurses was critical to the success of the project.

Programme: 59 weeks
Vision
The Trust required the most cost effective solution to the operational and serious health and safety problems arising from defective ceramic tiling and windows on the top seven floors of its' 12-storey Tower Block.
Challenge
To carry out the noisy and intrusive activities associated with the project without disrupting the delivery of clinical services. The 12 storey c.1972 Tower Block accommodates a number of key hospital departments, including Acute Wards, A and E, CCU and Outpatients. It is generally of rc frame construction, clad with ceramic tiles on cement render on concrete wall panels, and timber windows. Tiles were de-bonding because of freeze/ thaw action and timber sub-frames and casements were extensively rotten due to the level of exposure.
Solution
A partial scaffold and fan protection was erected as a temporary measure in advance of the project commencing. Works involved full scaffold and enclosure for all four sides of the seven upper levels of the building. Much of the scaffolding was erected off gallions brackets. Defective ceramic tiling was over clad with profiled metal sheeting. All windows have been replaced.
Benefit
Health and Safety risks have been negated, with maintenance costs expected to be negligible over the planned 10 year remaining life of the building. Works were carried out with virtually no disruption to the delivery of clinical services.
