We bought our first GPS unit in May 2014. A refurbished Trimble R6 and started undertaking small topographical surveys to support our main consultancy business. We were able to provide basic but practical information to supplement our designs which saved our clients’ money from having to engage with another contractor and undertake a fully blown, standalone surveys.
As time went on we developed a reputation for turning around surveys with short notice and to meet our clients increasing demand we purchased a total station to improve the accuracy of our surveys and to allow more difficult structures to be surveyed. We purchased a Trimble S8 Total Station in January 2016. With these two pieces of kit we were able to undertake very accurate surveys of structures using a local grid and tie them into the OS network using the GPS to establish control stations.
In November 2016 we employed our first full time Surveyor, Craig Warnock, who has brought consistency and radically changed the way we undertake and deliver topographical surveying. We changed our business plan from only undertaking surveys which were required as part of an ongoing design to producing surveys for standalone projects.
More clients started requesting height and stagger surveys to deliver rail works, principally bridge refurbishment schemes and to assist with this we purchased an Abtus height and stagger gauge which measures the height of the traction cable above the plane of the rails.
