Constructability in Design

TLDR: In this paper, the potential contribution of the consideration of design to improving constructability, illustrating the concepts involved through practical case studies, is considered, with a view to producing building and engineering details that not only have greater simplicity in themselves but in so doing are made more easy to construct on site.

Abstract: This chapter considers the potential contribution of the consideration of design to improving constructability, illustrating the concepts involved through practical case studies. Emphasis is placed upon the consideration of design elements and the empathy between design and construction, with a view to producing building and engineering details that not only have greater simplicity in themselves but in so doing are made more easy to construct on site. It should be emphasised, however, that the role of design is primarily to provide design solutions that meet the technical and financial needs of clients. The traditional design process is not focused on the production of the contractor. It is perhaps the responsibility of the contractor to better match the construction process to design needs. Where non-traditional procurement is adopted there is increased opportunity for a beneficial relationship between design and construction. Constructability at the detailed design stage is, obviously, the prerogative of the design team. Consideration of constructability at this stage demands that the following principles are incorporated into the formulation of the technical design solution and its elements: construction methodology; specification; accessibility; team skills.
