JHG learning from others!!
Information Communications and Technology (ICT)
The Fiona Stanley Hospital which is also a hospital built in Perth was completed in December 2013, it still has not open due to the ICT packages a State deliverable not functioning properly. This has been one of my major focuses for the past 6 to 8 weeks, ensuring we (JHG) deliver the ICT package early enough to the State to enable the State to have sufficient time to make Perth Children’s hospital (PCH) work. My main focus has been on the Central Communications Room 2 (CCR 2) and having it ready for commissioning on the 25th November 2014, which has involved all subcontractors from looking at UPS power, Critical Essential power, in row cooling, leak detection, fibre optics, copper cabling, earthing system and quite interestingly a carbon based anti static flooring. Which is has is a black carbon based primer which is the medium to conduct electrical current through it with a number of specific earthing points.
This system uses small copper strips and a conductive flooring which is a new system, compared to that of the existing systems which involved a full grid matrix of copper foil to interlink all the floor. The next phase is then pour and rolling the carbon based conductive flooring which is roughly 2-3mm thick and then do a physical test which is meant to represent the pressure of a foot and ensure the floor is conductive see photo below.
Quite an amazing product made by Sika the German paint company, I conducted the testing with Tercel the earthing company and it was an interesting experience. Below are a number of photo’s of CCR 2 including blown fibre tubing, copper interconnect cabling and all the electrical works to power the racks.
We have Power!!
On the 15th of September HV power was connected from the Central Energy Plant to the hospital a huge and extremely significant milestone for the project, this was the first piece of work which I worked on when starting the project. It involved a weekly meeting, factory acceptance tests of all LV main switch boards, air freighting equipment in from China and lots of hard work. It was delivered only two days after programme so a huge achievement by all involved. I have learnt a great deal about HV and the switching process and also Australian Standards on safety equipment and earthing.
The first part of the process after everyone was content that everything had been completed, all the inspection and test plans had been signed, was locking out of all the HV switch gear in PCH, then with coordination to ensure all HV rooms where clear of people the switching process began. Photo below show the actual switching on of PCH from CEP.
Mechanical subcontractor troubles
With continued trouble with the mech subbie, with no thought into how the large diameter pipework is being restrained caused a huge amount of problem, when they finally designed there support system and it was entered into the BIM 360 construction model. It meant weeks of modelling to get clash free before installation could proceed. This battle has continued with lack of documentation for welding certificates in line with the specification and the latest item which I have been investigation is all their commissioning sets being dramatically undersized. Looking at BISRA, CIBSE and the manufacturing guides lines valves on occasion where two or three sizes too small. See photo below for an example.
The pipe diameters where dropping from 65mm pipe to a 32mm commissioning set as can be seen above and the location of the commissioning sets and motorised valves are located to close to elbows, pipe reductions or locations which would cause irregular flow which would ultimately effect balancing and commissioning. The mech subbie now sadly takes up a large amount of my time due to the determination to cut corners, not build as per specification and proceed in areas which have not been coordinated correctly.
Aussie Living
On a positive note I am now swimming for a local club and will be going to the National Masters competition in Hobart Tasmania, Hannah has entered us both into a half Ironman in November great joy!! Hannah is also doing trails with the Australian Modern Pentathlon team. I am also still fishing 4.5kg snapper below and kiting when I can.

Olly,
Where do you stadn contractually with the subcon constructing without BIM co-ordination? It’s an interesting apsect of contract mangement evolution from the traditional “issued for construction” process and one which I suspect will need to be watched as BIM comes into ascendancy.
P.S. Nice to see you back on the blog after only two months gap this time, beats the three months between the last two. Must be an E&M absence of anything interesting to talk about issue?
Richard,
The process was for the design consult to deliver a LOD 250 model which will be progressed through the subcontractors design to deliver a LOD 500 to JHG and this would be issued to our Client. This will be a full interaction model with integrated manuals for maintenance will all online forms etc, which I am currently doing the first stages of at present.
Contractually all subcontractors are to deliver a full coordinated clash free model, this is made difficult as the first model from the design consultants was not particularly good and definitely not clash free. The process as it stands is to complete the model, clash free, submit drawings for approval and then after they have been approved then they go forward for Issued For Construction (IFC).
In terms of you last comment we can discuss this point in July 2015 but I believe Brendan and Nick have made PEW aware.

Anti static flooring, interesting and not something you come across everyday, so its good to see you being exposed to something a little less run of the mill. You may come across them again after phase 4 if youre involved with ESAs and have to arrange work to comply with ESTC6 so put anything you learn in the back brain!
Presumably the subbie is trying to get on to the next job, commission quickly and move on? Remember 65mm commissioning sets are expensive, there was probably a job lot of 32s in the yard
Any information on the earthing and the HV would be welcomed, may be I could in corperate it in my lectures. Thanks John
Mark,
Please see my next blog to show what has happened with the commissioning sets. In terms of the anti-static flooring yes very interesting and also very new. So will lock that info away for the future,
John,
What info are you after? I have all the test results for all the HV switch gear including their High Pot and Megga tests, also test results for all the HV cables. We also completed the HV switching from 6.6kV to 11kV to site which was good, changing the internal tappings of the Transformer and terminating the new cables. We are now moving into the LV side and the first termination will be to our MSSB into the main Mechanical Plant Room in the basement which is a 800 Amp feed. We are also terminating all the large VSD’s for the pumps so a very interesting couple of weeks ahead. I will put a pack together and send it through on email if its not too large.
