The MechanicalServices scope of works comprises the provision of Mechanical Air & Water, MechanicalElectrical, BMCS and Pneumatic Tube Services. The Mechanical Services includes the complete design, supply, installation, testing, commissioning and maintenance of the works.






1.    Open services riser spanning five levels containing CHW, HHW and refrigerant pipework, ductwork, pneumatic tube, cable trays presented safety issue due to fall risk

2.    Minimal plant room space on a number of Levels

3.    Building was better sealed than the anticipated 0.5 ACH resulting in over pressurisation during fire mode

4.    Pandemic mode – design/installation of a new dedicated AHU and exhaust fan serving ICU pandemic area – requirement came in at the end of the job when plant rooms were already designed and partially installed


Engineering Solutions

1.    Designed, supplied & Installed prefab riser

2.    Replaced single zone AHU’s with multi-coil AHU’s

3.    Redesign of the fire matrix late in the project; final result was turning pressurisation air handling units off in fire mode – still easily achieving zone pressures

4.    Detailed coordination, redesign of risers (including new slab penetrations)
