The 24 King William St project involves transforming a dated and under-utilised 1980s steel framed office building into a new attractive and lettable building on this prominent location. To add value to the site a new 3 storey mansard is being added to replace the existing roof plant area providing an addition 20,000sqft of net internal area. Elliott Wood was trusted with the responsibility of demonstrating that this additional floor area could be accommodated onto the existing structure without the need to undertake any costly strengthening works to the existing frame or the foundations and to maintain occupied retail units on the lower floors. Our approach was to fully understand the building’s strengths and weaknesses in order to target surveys and focus strengthening works onto key components rather than entire structural systems. Existing building drawings were obtained and extensive back analysis was undertaken on the structure to gain a detailed understanding. It was found that the stability system, in particular isolated moment connections between the columns and floor beams, were the components which required strengthening. Our targeted approach resulted in a proposed scheme that included zero foundation works and minimal steelwork strengthening which in some areas consisting of simple bolt upgrades.
