Murphy Surveys Ltd were appointed to undertake a measured building survey of a historical site within Dublin City Center. The project involved high quality surveys of areas of most concern with surround buildings and topography surveyed as context to different degrees. Our BIM survey would be used as a starting point and background for a design BIM process. Overall the project area covered c. 20,000 square meters consisting of dense urban heritage buildings approx. 4 storeys high for much of it. The environment was extremely complex and intricate with basements featuring a maze of different barrel vaulted ceilings, as well as floors and walls that were sagging and warping to a high degree in many different planes and sections. Varying constructions also made it hard to understand the spaces easily on a project of this size.
The Wellcome Wolfson Institute for Experimental Medicine (WWIEM) is an innovative and pioneering bio-medical research and development facility. The laboratories are arranged around a central atrium which encourages collaborative working with transparency across the building between research spaces. The concept maintains a clear adaptable floor plate, free from service risers by routing ductwork vertically on the building perimeter within an energy efficient double skin façade. The building celebrates the science that occurs within and is an exemplar of sustainable and carbon-limiting laboratory design. The building’s energy efficiency and forward looking low carbon design has made a positive contribution to the University’s target figures and sustainability commitments in managing its estate.
The aim was to provide laser scan surveys and an accurate BIM model of the site and surroundings that could be used as part of a BIM Design and retrofit project of the heritage site in question. This model would need to be set up in accordance with PAS 1192 and would require information, such as, material changes and detail items like cornicing, radiators, sills and site surrounding hardscape and set up as linked separated files which could be used in a variety of ways for the BIM design project.

The building has a BMS system that links directly to a central estates energy monitoring system and the building will be monitored seasonally against energy performance targets. The project has been at the cutting edge of BIM technology in Northern Ireland. BIM was successfully used as a tool for the design development, fabrication, installation and operation of the facility. It has broken new ground for Queens University Belfast as the information stored in the BIM model will be used for facilities management. BIM has been adopted across the project supply chain to enable better project outcomes to be realised. The use of BIM has been seen as a path finder for the whole team including the client in order to derive efficiencies and lessons learnt for WWIEM and future projects across the estate.
