Concrete beats steel in school tests
The Concrete Centre News Archive 2007
Release date: 15th March 2007
New independent research confirms that concrete offers the best overall economic solution for school construction, beating steel in terms of cost and lead times. Concrete-framed construction was found to be up to 6.4% less expensive and up to six weeks faster. In addition, concrete construction offers schools a range of extra value benefits at no additional cost.
The independent research conducted for The Concrete Centre included a cost analysis of a typical secondary school long-span and short-span construction, comparing reinforced concrete and steel-framed options, taking into account construction times and the effect of programme on cost.
It was noted that the most economical concrete-framed solution, the post tensioned flat slab, was found to be up to 6.4% less expensive than steel-framed solutions. Furthermore, Slimdek steel-framed solution proved to be 6.8% more expensive than a concrete post-tensioned flat slab solution, and was found to be 63% more expensive if only the cost of the frame was considered.
The concrete-framed options proved to be a few weeks faster in terms of speed of construction, with a calculation of 81-83 weeks (taking into account procurement and lead times as well as construction duration) compared to 86-87 weeks for the steel-framed options.
