An information-led process framework for hybrid projects

Building adaptation is the broad term used to describe any work to a building beyond maintenance. A hybrid building project is a phrase used for the benefit of research, to define a type of adaptation project where new elements or buildings are combined with existing buildings within the same spatial boundary. The hybrid building process of addition or extension of spatial, structural, façade systems, etc. should result in a singular compound building and not a building of separate parts. The hybrid process has similarities with traditional new build projects but it also offers unique situations that often require a different approach. This is because the approach to design, planning and construction will differ for adapting an existing building, compared to new build. In addition, as-built information will directly influence the design-specific stages of the process. This paper presents a comparative study of design-related variations using the standard RIBA design process. The result was mapped to highlight information, decision and activity flows for a hybrid project framework which has been evaluated by industry experts. A summary of findings from the latter is also presented.
