Project commissioning (T&C) is the process of assuring that all systems and
components of a building or industrial plant are designed, installed, tested,
operated and maintained according to the operational requirements of the
client.

Before fault tests are carried out, the value of all set points (AI/AO/DI/DO) are
recorded from the BMS system are validated by the T&C engineer to determine
whether it is operating normally.
Fault test:
A1 When the System is in “Manual Mode”, DDC will stop the Chiller Plant Operation
A2 In “Auto Mode”, startup of the automatic Chiller Plant Operation will follow the BMS
time schedule
A3 Whenever the time schedule is “On”, one set of chiller/CHWP will always be running
A4 DDC Controller will switched on the lead equipment (chiller/CHWP) first unless fault is
detected in the equipment
A5 Each group of equipment has its own lead/lag rotation sequence which is independent
from each others
A6 Lead/lag rotations are changed daily

A manual is prepared by contractor which includes the
guidelines that Facilities Management (FM) Team of the
building must address to ensure that the operations and
maintenance of the installed chiller system is in good
condition. This extends beyond the in-house staff to any
contracted services as well.

Based on the energy saving estimate illustrated, the performance of the new
chiller plant is acceptable. The accuracy of saving estimate will be further
determine by tracking and documenting of the saving estimate for the next five
months.
Fine-tuning strategies:
1. Validate installed equipment and control schemes meet specifications
2. Validate modelled expected building load calculations
3. Validate installed equipment and control schemes operate and perform as specified
4. Check metering performance periodically to ensure meter functions properly
5. Water temperature, differential pressure to be reset seasonally
6. Sequencing of chiller
22. Bollard Procurement
This project involved the installation of anti-ram bollards to enhance the security
of the building according to our client’s requirement. A total of 9 bollards (4
fixed, 5 removable) shall be installed. There are Anti-Ram Standards to comply
with. The fixed bollards have to meet UK PAS 68 2007 (7.5 tonne at 50kph) to
protect the perimeter of the building.

Editor's Notes
Summer Internship Start & End Date: 23 June to 28 August.
Presentation rundown:
Introduction of the company profile
Training activities within the company given to interns
Chiller Replacement projects under my line manager
Bollard procurement – another task I was assigned
Takeaway – summarized my working experience in this company
EC Harris – built asset consultancy firm.
It is now an Arcadis company.
Goal of the Company – Generate the best possible solution and outcome for our client.
First week in this company – Induction program.
Information Risk Awareness Training – a training provided to us regarding the P&C issues.
Safety, Health & Environment – SHE.
Risk assessment – Test our knowledge on some anticipated risk.
ECH Harris Academy – Training in their academy which are compulsory. Some are modules provided for our own interest.
“Green Card” – I obtain this certificate on 31/07/2015.
Chiller replacement projects for commercial buildings.
Our role – PM.
Engage with the design and build contractor to provide turnkey solution for the replacement of existing chillers.
Highlighted in orange – For that these projects under my Line Manager are similar, thus, I would only present the chiller replacement project for TST.
By the time I join ARCADIS, this project is already at the stage with the dismantle of old chillers and installment of new chillers had been done.
Involved in the inspection of building defects, T&C, Project Handover and M&V.
Below presenting those process/task I was involved in, there is a brief description of the design condition of this project.
Point out that COP, which is the performance of the chiller is important.
It is an important aspect for this project.
The table shown T&C Record that has to be done for this project.
Piping hydraulic test
Water analysis report for flushing
BMS system
Chiller unit
Chilled water pump
For example A2:
There is a BMS time schedule where will show the operating time at different days. While the chiller plant is operating at “Auto” Mode, it has to follow the pre-set time schedule.
An interphase of the BMS system which provide important parameters.
Alternative commercially available bollard which fits our requirements?
Supplier/Contractor with related work experience which could provide us a clue to resolve the on-site constraints.
Solution for Area 2, contact existing supplier/contractor to check whether the electrical wires of the road blocker system are installed underground or there are conduits which are hanged at the basement.
Installation work – How to carried out?
Proposed work cost – whether it is reasonable and its quality are upmost important to deliver our companies’ goals.
Theoretical knowledge would not be enough in the real life application of engineering works. There are lot of things to be considered to produce desired result.
First taste of work experience in Hong Kong.
Meet and network with so many people of different background.
Elephant – 22 months to be exact. It has one of the longest gestation periods in the animal kingdom.
Blue whale pregnant for about 1 year.
It shows that the company emphasized a lot on the safety. It helps to create awareness.
Workshops such as Yong Talent Meeting – MBTI, Training with interns – get important feedback from line manger, Communicating with impact – benefit me a lot
How we can all contribute.
