The Society of Chartered Surveyors (SCS) have announced following a recent study that tender prices have decreased by 17.3% over the last 12 months to levels not seen since 1999. The dramatic fall has been caused by the drop off in demand for construction projects in all sectors including residential, commercial, public sector along with civil engineering schemes. The study states there was significant drop off in the last six months of 2008 and that this has continued into the first six months of 2009.
