ICT innovations relating to the construction industry have been rapid, offering the potential for efficiency gains and improved business effectiveness. However economic considerations, industry-specific conditions, legal, and business issues have limited their adoption by multi-firm, temporary project organisations. ICT adoption rates are the manifestation of boundedly rational business decisions, shaped by personal attitudes to innovation. Although attitudes are personal constructs they are phenomena that are experienced, can be personally reported, and observed by others. Recent research has mapped the influences shaping the attitudes of decision-makers, revealing that their decisions are shaped by their developing perception over time of human, business, and innovation- specific considerations.
