3 Commissioning and Integrated Testing Strategy
3.1 Uprating of base build air handling plant
The Rebalance and adjustments to existing building plant are not part of the main
contractor’s scope of works. Arup have developed the following proposals to address this.
Air Systems
ICL have agreed to the Arup recommendation to appoint NDY as technical advisor to their
maintenance team to allow them to make the necessary adjustments to the main building
plant and act as liaison between ICL and WL/Axima on the rebalance of the systems. This is
a more efficient approach than appointing an external commissioning engineer because
NDY have all the necessary knowledge and familiarity with the systems and parties involved
already.
NDY have advised that this work will not affect the lower floors because that is a Constant
Volume air system so a full rebalance should not be required.
WL have advised that this work can proceed before final commissioning of special extract
systems.
This work was completed on Friday 1 February 08.
Chilled Water / Low Temperature Hot Water
ICL have agreed that the systems can be signed off on the basis of the proportional balance
carried out by WL using temporary pumps.
A full rebalance may still be necessary post completion. Arup have obtained a quote for this
which is being reviewed and will be issued to ICL.
3.2 Commissioning
During commissioning the various installations and plant items are tested and balanced as
individual entities to ensure that they perform to the required design duties. The culmination
of the individual testing establishes the completeness of the systems and by definition the
building to proceed into the integrated testing processes.
Walter Lilly are responsible for commissioning have developed a commissioning program
which can be seen in Appendix E. Four important milestones have been selected for
monitoring the progress of commissioning at a strategic level. These are:
o
o
o
o
Main air systems
Special extracts
Fume cupboards
Chlorination
Banyards are responsible for witnessing the commissioning. A tracker has been developed
to indicate the progress of this, an example of which can be seen in Appendix F.
3.3 Integrated Testing
This period is specifically to ensure that all of the above is definitively integrated as
determined by the design and specification requirements and incorporates all of the design
changes instructed throughout the duration of the installations.
