  • "professionalism, integrity and commitment to our Project outcomes"

    Boeing recently encountered a high priority need to establish fibre optic cable at one of our Operational sites. The time-critical nature of this need initiated a search across a range of suppliers who could satisfy very stringent requirements for schedule, flexibility, cost and quality. It very quickly became apparent to us that Craig McIntosh’s team at GNB Energy provided the best value option for our needs. From the moment Craig and his team signed on to the task, they never disappointed. Communication was fantastic between us; their clarity and honesty about the timeline and risks were outstanding…this ensured that we could continue effectively juggling the key Programmatic requirements on our side. Further to this, the completion of the task by Craig and his GNB Energy team during trying conditions went perfectly. On behalf of the Boeing Team, we like to thank GNB Energy for the professionalism, integrity and commitment to our Project outcomes.
