By closing the gap between conceptual design and the documentation required for construction, building information modelling (BIM) promises to revolutionise contemporary design practice. This issue of AD brings together a group of pioneering academics, architects, engineers and construction managers all of whom are engaged in the use of building information models in the actualisation of complex building projects, from design stage to construction. Key texts trace the development of building information modelling technologies and address issues of collaboration, design and management, while featured projects systematise the use of BIM in contemporary design practice for students and professionals alike faced with considering these tools within the changing marketplace. •Covers a core area of technological development: BIM systems that span the gap between the design, manufacturing and construction processes. •Key contributions from: Chuck Eastman, Cynthia Ottchen and Dennis Shelden of Gehry Technologies. •Features work by: Asymptote, Greg Lynn FORM, KieranTimberlake, Morphosis and SHoP Architects.
