Chief construction adviser Paul Morrell compared the 鈥渋rrational exuberance鈥 in recent architecture to the hedonism of the financial markets in a speech yesterday.

Delivering the 2010 Povey Lecture in London, Morrell called for public projects to set 鈥渕aximum design standards鈥 as well as minimum. He warned that good design had to produce value, and added that 鈥渄esign that celebrates little apart from itself is bad design鈥.

Morrell also called for greater attention to be paid to whole-life costing and cost benchmarking, and repeated his calls for greater supply chain integration and for 好色先生TV Information Modelling to be used on all public sector projects.

Morrell鈥檚 comments came days after the government revised down its estimate of construction growth by more than a 拢1bn, in a move that is likely to knock 0.2% off the nation鈥檚 recorded growth.

The revision follows the receipt of further data and a revision of the methodology of recent estimates, which produced record growth figures for the industry over the past six months.

The Office for National Statistics said that growth in the second quarter had actually been 6.8%, rather than the 9.6% previously recorded.

In addition, the decline in output in the first quarter was more severe than previously recorded, at 1.2% rather than 0.8%.
