Hybrid-Thumb Crumlin Childrens Hospital


This design-build project was delivered on time and within budget through the use of Building Information Modelling (BIM) by an interdisciplinary project team with RPS serving as Mechanical and Electrical Consulting Engineer. 

The M&E design was carried out in a Federated BIM Level 2 model. The project consisted of a three storey development with an undercroft area for car parking, a hybrid catheterisation lab and orthopaedic theatre including an ultra clean ventilation system and all ancillary spaces. The third floor is an internal plantroom containing all the plant items necessary to serve the building. Both the lab and the orthopaedic theatre are served by individual air handling units complete with HEPA filtration and heat recovery to provide ultra clean air and energy efficiency for areas with high air change rates. All life critical electrical systems are backed up with UPS and IPS as required for medically used rooms.

A link bridge was constructed to link the new facility with the existing theatre block. Careful planning was required to achieve the tie-ins to the existing services to ensure any down time to life critical systems was minimised. Backup systems were put in place to ensure continuity of service in critical care areas at all times during construction.
