Rockbrook have played a critical part in the developmental and maintenance of Dublin Airports Airfield Lighting Control System since 2006. I have always found that their team to be highly skilled and competent. They possess a large wealth of experience gain from other sites and are always available to provide advice especially regarding options on maximising the safety of operation. Their level of service is consistently high, shown commitment to programme, have been flexible if agreed dates change. Rockbrook have built up an excellent working relationship with our design and asset care departments and with the Control Tower staff of the IAA. Their collaborative approach mirrors the four pillars of the Dublin Airports values ethos which include Brilliant at the Essentials; Respecting each other’s Value; Passing the Baton, not the Buck; and Always Better. As a result of the successful completion of amendments and their support/maintenance of the system over the years a high level of confidence and trust has now been developed by Dublin Airport in the Rockbrook team. Rockbrook are considered an integral part of the Dublin Airport’s airfield team in delivering this.
