Renovation and refurbishment of 1960-70’s office buildings is now a key focus of international investment in Ireland. This project at Dublin Airport, by PERSPECTIVE Dublin for the refurbishment of an 8200 sq. m six storey building is one such project. This is a Design-Build Competition which includes the provision of high quality, flexible, Grade A office accommodation and refurbishment of the external envelope and services design to achieve a LEED Gold accreditation and an A3 Building Energy Rating. It is required to bring it to the market quickly and facilitate phased handover for early tenant occupation. We have adopted a Building Information Modelling (BIM) process in preparation of the tender proposal. This process has allowed us to comprehensively consider and test solutions, and make informed decisions. This has provided us with greater cost and programme certainty in developing our approach to the project. Our ‘smooth handover’, BIM to FM, manages phased handover for tenant fitout and occupation.
