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. RACA
