One of the largest project roles HJK has been involved in was the Wellington Regional Rail Project which involved
initially procurement specific roles which morphed into peripheral scoping, procurement, installation and construction roles.
The first was for evaluating and shortlisting civil engineering contractors for the upgrade of railway station platform
upgrades and used a weighted attribute methodology which HJK developed specific for the purpose. Next, the project
required the evaluation and recommendation for a design and build contactor to supply the HVDC power equipment for
its new sub stations. Again, HJK used a weighted attribute methodology developed specific for the purpose and through
a rigorous process involving 2 shortlisting stages and peer review for probity purposes ABB NZ Ltd was awarded the contract.
HJK went on to set up the design coordination between ABB and Fletcher Construction who were constructing the substation
buildings the equipment was housed in. HJK then transitioned into the scoping and procurement for the SCADA hardware and
software, interface equipment between the SCADA and power equipment at both ends plus the fibre optic WAN linking them
altogether. This involved working with Power Systems Consultants together with Kiwirail staff to develop exactly what
the operators wanted to see and use in their new SCADA system, documenting that and setting up all the procurement
documents for the 3 separate contracts that were involved. In the end Realflex were contracted for the SCADA hardware
and software, Invensys process Systems for the RTU's and United Group for the WAN. A process involving software development,
database development and coordination and lab testing of power equipment and RTU devices was overseen by HJK through to
installation and commissioning. The installation and commissioning phase involved exposure to Kiwirails rigorous health
and safety procedure and systems in HV sub stations and the rail corridor. The foregoing occurred over almost 2 years
simultaneous with other projects for other clients, and was a busy time for HJK.
HJK has more recently been involved with Kiwirail on its properties in Invercargill which have involved enabling works
involving services rerouting and buildings demolition to assist one of its stakeholders, Mainfreight in establishing its
new terminal on the site. This work also involved the development of another part of the Invercargill site to a new paved
yard for another stakeholder, Halls. These projects involved basic design and civil works procurement.
HJK understands the operational constraints involved in working in the rail corridor and together with the demonstrated
expertise in solving complex engineering problems are an ideal resource for rail orientated projects.
