The project comprised the construction of a paediatric cardiology unit on top of an existing two-storey PICU building, and measured 1,250m2 in new build area. This was a Design and Build project led by Clancy Construction.

The site posed numerous challenges. Firstly, the existing two storey building below was constructed in a confined courtyard between original hospital buildings. The building was constructed to within 4.5m of original buildings on three of the four sides. The fourth side was within 5m of the main live public carpark.

Secondly, as the building was being used for extremely sensitive medical purposes, there was a requirement for the structural vibrations to be limited in accordance with the requirements of HTM 08-01 Acoustics, and a complex modelling exercise has to be carried out to calculate the vibration response.

Thirdly, the existing building was constructed with columns being extended above roof level. The design for the additional storey was restricted to an allowable permitted loading at each individual column location.

The overall height of the building was set by the planning authority, which resulted in complex coordination of structural member sizes for strength, deflection and vibration in respect to existing roof finishes, under floor services and ceiling services as well as obtaining the specified internal floor to ceiling heights.

There were two link bridges that connected the new building to the existing perimeter buildings. These structures required alterations to the original buildings, with appropriate movement joints incorporated within the design.
