Published every quarter, they will examine the key cost drivers for different sectors, provide a building type specific cost comparison and include a cost table with indicative cost ranges for various frame types.
These cost ranges can be used to act as a comparative cost benchmark. Subsequent articles will include cost comparison updates for each sector to ensure the cost data remains current.
In the first article’s cost comparison, the 10-storey One Kingdom Street project in Paddington, west London (pictured) is examined. This grade A office building was originally part of the Target Zero study, which provided guidance on the design and construction of sustainable low and zero carbon buildings.
The updated cost comparison for this project shows that a steel composite solution was 7% lower than a post-tensioned concrete flat slab alternative in terms of the frame and upper floors, and 5% lower on a total building basis.
Over time the cost guidance series will comprise studies into commercial, education, mixed-use, retail and industrial buildings. Each article will also examine the process of cost planning throughout the design stages, and provide a market update on tender price trends.
