Competitive tendering is something architects have become all too used to, but Monmouthshire architect Liddell & Associates has turned the tables by asking three CAD providers to bid to be used on a specific refurbishment project, to create a new life for a disused Victorian church. In this case, however, the bidding was to do with time, not money. The architect took a set of drawings from a new church it was working on that had an unusual roof profile, and asked the suppliers to see how quickly they could get it on their CAD system. One declined, another took three hours, and the winner, ArchiCAD, took only 20 minutes. As a result, the practice adopted ArchiCAD to create the complex model that showed the church in the context of the town.
