Everyone wants BIM case studies but coaxing them out of members is proving to be a real challenge. The BIM Theme Group has worked tirelessly to develop a simple proforma which can be used at all stages of a project or programme. The aim is to build a library of relevant and helpful examples. John Lorimer, chair of the Constructing Excellence BIM Theme Group, launched his own initiative at their last meeting held on 1st April in Leeds. He will give a bottle of Champagne (the proper stuff) for each case study submitted. A case will be purchased and given out on a first come first served basis – unless they are consumed in the meantime.
