Projects floating ceiling panels and align with the network of exposed steel trusses. Local reception desks are provided with underfloor heating to improve local thermal comfort in winter. The auditorium is served by a dedicated air handling unit via high volume radial diffusers and double noise attenuators. Lastly, the central server room is served by a dedicated up-blow DX CRAC unit in a cold-isle configuration, and the patch rooms by DX blower coil units. BMS SYSTEM A modern BMS system was installed at UP Engineering 4.0 to monitor and control all HVAC systems. The system has its own standalone IP network and comprises a series of field controllers in all the plant rooms, connected to a central front-end computer. The front-end is web-based, enabling remote or offsite connectivity when needed. The BMS facilitates full interrogation of HVAC systems, including set point management, all control parameters, room conditions, water temperatures, system statuses, and all system scheduling. Automatic alarming alerts the user to any problems such as tripping statuses, dirty filters or high temperatures. Selected other services are also connected and monitored, including the compressed air plant, laboratory gas alarm panels, fire panel, generator and transformers. Continuous historic trending and logging of all conditions, loads, statuses and set points ensures traceability and enables informed decision making and tuning of systems to improve efficiency and service delivery. PROJECT TAKE AWAY A project such as this can only be a success if a team of individuals work together and bring their expertise to the table in an enterprising way. As end-user client, Prof. Wynand Steyn (head of Department Civil Engineering) and Johan Scholtz (Laboratory Control instructor) ensured that complex design requirements were clarified and ensured throughout the project that the end product is nothing short of world class. The draughtsperson, Stephanie Esterhuizen, ensured the complex systems are accurately modelled in Revit and the design is well coordinated to ensure workable solutions. Andrew Wills and his team at Airgro did a great job with the mechanical installation and challenging commissioning requirements. Riaan van der Walt provided a state-of-the-art BMS and control system installation. Overall, the end-user client is very satisfied, appreciative and excited about the world-class mechanical engineering services design and installation at the facility. UP Engineering 4.0 is an inspiring example of a facility where building services star one of the leading roles in the functionality, sustainability and aesthetics to create a comfortable and educational environment to its occupants – by engineers, for engineers.
