The reason we are able to highlight this project prior to its completion date is that the bulk of the in ground earthworks have been completed and this project in particular highlights the management skills of Affinity Electrical and our proposed subcontractor National Directional Drilling

With the project only having a performance specification for civil components designed by ARUP consulting Engineers, under the superintendence of Cox Architects, it was really up to AET to come up with a best case solution to the conduit reticulation on this site, as well as building footings and pits for the cable reticulation to pass through.  Throughout the construction of the Manuka Oval Lighting and very, much during the in ground services portion of the project we have indeed had to have a strong commitment to understanding the site and its uses, so that we can best manage the stakeholders, client and constructions competing interests. 

The client on this project comes in a few forms, these being

  1. Australian Federal Government – NCA
  2. ACT Government – Economic Development Directorate
  3. ACT Government – Territory and Events Portfolio

The On Site Managers on the project are:

  1. Venue Manager – Matt Tokley
  2. Venue Green Keeper – Brad Vandem

Super intendants:

  1. Cox Architects – Ian Smith
  2. Arup Consulting Engineers – Andrew Greenwood

The Site Stakeholders & primary tenants of the Site:

  1. AFL Canberra
  2. Cricket ACT

AET Clients:

  1. Dialight Australia
  2. Abacus Lighting – United Kingdom

What we identified from the start was that the site gets use basically every day of the week from various users.  The Bradman Pavilion gets used by both private and government clients because its size and proximity within the Capital. 

One of the issues identified on the first day was the problems on the site with vehicular access.  People using Manuka Oval believe that they can park anywhere within the site to changing the culture of car usage was first.  Coming up with detailed scheduling plans so that we can move our materials around the site while maintaining safety.  See below for our lifting plan for the light towers.  This project also runs across the changes of season between winter and summer which is the busiest time of year for green keepers to prepare pitches.  With this years summer of cricket we had to allow the venue’s green keepers, staff access to the oval as well as the practice wickets external to the venue so that they can continue operations.

Finally the stake holders being both AFL Canberra and ACT Cricket.  Allowing fit young athletes access to practice wickets, keeping them focused of safety areas and maintain the balance between required use of the venue versus culturally what the stakeholders had always done in terms of access.  We have had to be upfront with them about the use, but also getting “buy in” from those stakeholders so that no one was put at risk during the in ground works across the venue. 

Because our actual client on the project is working from England this meant that Affinity Electrical had to be vigilant in our management of the site, we determined early that decision that were to be made had to be made early, and with as much planning as possible to have the best outcomes for the above mentioned stakeholders of the project. 

With regards to the in-ground portions of the project after being awarded the project under the head contractor Dialight Australia AET went to National Directional Drilling to devise the best way to get these conduits into position with the following issues

inground servicesTTM & PTMManage and Maintain pedestrian and vehicular access to the site.  As anyone that know Manuka Oval would appreciate this venue gets used by Cricket and AFL all year round.  Because this site is a working, “living site” these tenants need to managed across the course of construction to allow them safe egress but to also maintain the construction site integrity as work site.  This site also has its own machinery which needs access to all areas of the facility and our ability to have sites that have been worked through, back to allowing machinery for the ovals green keeping staff is also paramount. 

A key component of managing this site safely was maintaining our temporary fencing to stop or avoid trip and fall hazards.  As you can see from the photos, we have some detailed and deep excavations on this site, which posed a considerable issue if someone was to fall into one of these holes.  At the start of the project we identified the vigilance required to maintenance on our temporary fencing and this was highlighted throughout our daily work sign ups.  This indicated to our staff that they weren’t’t able to leave a site unattended and without  a temporary barrier in between Manuka oval stakeholders and the fall hazards that exist.  These issues if found during the course of the day are highlighted for review at the next meeting.  This enabled us to maintain the fence line and not allow breaches of safety to the project.  We were able to get subcontractor buy-in to this process by highlighting the importance of key safety outcomes, to a point that ACTEWAGL on induction of their staff also understand and were great performers in this key safety outcomes.

Inground Services:  and in particular our ability to avoid and manage any in ground issues that arise has been a success of ours on this project.  The site, is over 80 years old and records of what has been installed on the site are sketchy at best.  It has its own substation on the premises that sits right in the path of our conduit reticulation.  This is an example of our ability to manage the problem, plan the solution and have a outcome that maintains the safety of our staff, and the stakeholders of the Manuka oval.  Obviously the site is littered with other services like, sewer, telecommunications, water, irrigation, gas and the only service that we have encountered is a sewer line during the construction of the 2 x 1 Megawatt sub-station on the eastern side of the oval.  The advise from the Super-intendant was that there is nothing in the vicinity.

Restoration of Surfaces: was paramount in our thinking when we decided to under bore the whole conduit reticulation across the site.  AET knew what a mess of the facility open trenching would make, and while it would have been easier to lay our conduits NDD have experience in getting multiple conduits to the correct positions with 1 x conduit pull.  The oval has a service road that rings the facility and a fair portion of this is loose gravel in its make up so we needed to maintain the integrity of this road to avoid having large restoration at the projects end.  I would also like to highlight our ability to manage heavy machinery across the site to keep the restoration to a minimum.  We used ply board under machinery where necessary to transport the large equipment and not damage the superficial surfaces.  These machines include

  • 1 x 15 tonne piling machine
  • 1 x 30 tonne crane
  • 1 x directional bore machine
  • 3 x 8 tonne excavators

All of these machines were managed through rain and wet days in a way that would least disturb the surfaces and that would allow pedestrian, and vehicular access throughout the site.  While the full restoration isn’t completed until the 200 Crane exits the site, we are confident in our installation methods having the least disruptive effects on the surfaces to have to remediate. 

Engaging & Managing Subcontractors: for this particular site with all of the ACT & Canberra sporting people looking over it, we needed the ability to manage the portions of the contract that we weren’t familiar with.  AET has a proud tradition of putting cable and conduit in the ground, however bringing together the electrical components of the project along with hard civil, detailed civil, concrete, steel works, lead us to seek some assistance in protecting our business as well as the clients integrity.  AET engaged Russell Boyd from Projectum to assist with our management systems on site and to also assist with our managing key outcomes.  These being budget, program, installation certification and contract.

Obviously to complete such a detailed infrastructure installation we required the assistance of multiple of subcontractors.  Our ability to get the following subcontractors all assisting and working together is testament to our ability to manage subcontractors.

  • Footing Design & Certification – AWT consulting Engineers – Darren Salt
  • Geotech – Coffey
  • Site Survey – Land & Data Services – Bill Campbell
  • Conduit and Pit Installation – National Directional Drilling – Dean Hall
  • Detailed Excavation – Indetail Earthworks
  • Pier Footings Piling – Hyatt Ground Engineering – Brendan Muldoon
  • Steel work Installation – Tricivil & One Steel
  • Concrete – Tricivil & Elvin Group
  • Power Supply – ACTEWAGL Networks – Raul Tinio
  • Sewer Relocation – ACTEW Water – Bruce Reid
  • Sub-Station Construction - ABA Construction – Mohammed Wazir
  • Communications – Pathway Communications – Andrew Peel
  • Building Approval – Certified Building Solutions – Chris Southwell

Managing this subcontractors to protect our clients interests and de-risk this project has been paramount during construction.  As you can see from the detailed footing design we had 13 meters bored piers in very tight positions across the site.  AET’s ability to manage the safety of the installation and the progress of the installation meant that we had numerous concrete pours because we wouldn’t risk having 13 meter holes left exposed with only temporary fencing around the work sites.  As you could imagine this comes at a cost disadvantage to AET however the risk to the project was highlighted and appropriate action coordinated.  We highlight this as a fact that our management systems work in the way intended and shows our ability to cross control multiple subcontractors. 

Dealing with ACTEWAGL on the project can sometimes be problematic, however with early engagement process we identified the issues, problems and potential risk to safety and program.  We provided all information upfront to ACTEW for asset update and acceptance and found that the substations were installed on time, and with AET ability to pay the sewer works upfront no time was lost dealing with ACTEW water.
