Ventia Boral Amey Joint Venture (VBA JV) manages the Sydney South Stewardship Maintenance Contract, awarded by NSW Roads and Maritime Services to deliver road asset management services over seven years, valued at $100 million per annum.

VBA JV Sydney commenced service delivery on 31 March 2014. In addition, VBA JV has constructed over $75 million in road improvement works on behalf on Roads and Maritime to date.

Since the inception of the contract, NA Group has been a key service provider for VBA JV. Their areas of expertise have included road construction and civil works but they are more than willing to assist wherever possible. When required for Incident Response, they are dependable, competent and professional. They are proactive with supplying solutions, and exemplify the teamwork value of VBA JV with valuable contributions to our WHS&E systems.

NA Group’s solid commitment to safety, efficiency, quality and environment has been evident in the incident free completion of many key projects. They have an excellent safety system, giving confidence in their ability to not only complete works on time and to specification, but most importantly, to ensure that everyone goes home safely. This requirement is non-negotiable by VBA JV and NA Group has not disappointed.

Their professional, can-do attitude has been a vital element in maintaining the high standards demanded by VBA JV and our client, NSW Roads and Maritime Services. NA Group Director Nick Argyropoulos leads from the front with a personal oversight of and involvement in all work undertaken for the joint venture. This accountability is reflected in the culture and work ethic of all NA Group staff.

I regard NA Group more as a partner than a subcontractor in their attitude and approach to innovation. I unreservedly recommend them to any business seeking the highest standards in roads and civil works contractors.

NA Group assisted Brefni with the supply of site batched concrete using their Mobile Batching Unit (MBU) at a remote location on the Central Coast.

Logistical restrictions accessing the site at Wondabyne meant that there were limited options for traditionally batched concrete, resulting in the MBU having to be mobilised to the site via barge along the Hawksbury River. NA Group staff were extremely attentive and resourceful when planning the works with Brefni to ensure that suitable material and provisions were in place ahead of the tightly-programmed rail possession works.

Further flexibility and professionalism were demonstrated when on site, with the ability of the MBU to change mix designs and/or slumps to suit the conditions of the build. This was a well-managed and risk assessed solution which successfully achieved the desired outcome under some unique and logistically challenging circumstances.

NA Group recently completed expedient pavement construction on a critical road intersection.

From the early involvement in the planning and construction staging with their management right through to the delivery of the constrcution works I cannot fault them. The works required three mobilisations and their crew to completed the pavement works in a short time frame.

I was impressed watching the site team working with limited conversation or direction required as it was clear to see the individuals all knew their own tasks combining to work as a team.

NA Group delivered a quality program at all levels.

It was refreshing to once again find a company of such quality and proffesionalism that we entrusted the spray seal program with complete confidence.

From Senior Managment to the work crews onsite, all NA Group personnel we dealt with were extremely professional and had "can do" attitudes. This culture is deeply entrenched in their day to day business, which makes working with them extremely easy and mutually beneficial.

I had the pleasure of working with NA Group on the B Line Project where they consistently completed slab replacement and miscellaneous concrete work on a nightly basis over a one year period. No task or change was too difficult, with NA Group going above and beyond on multiple occasions to ensure all our needs were met. The expertise and knowledge and NA Group brought to our project was invaluable. Being an industry leader in RMS slab replacement work, NA Group were able ot provide great insight and advice with regards to resolving challenging situations whilst providing a high level of comfort.
