Topographical Surveys

Land Surveying, the foundation of the Mason business and its primary activity today.

We are involved with surveying all types of sites, including roads, airports, railways, urban and rural areas and construction sites. Control can be established and coordinated to a local grid and datum or on National grid and datum using dual frequency GPS units. Detail is captured using the latest high precision total stations and Network RTK GPS units. Data is Quality Assurance checked before being passed to the client in the requested digital format and to the required CAD Standards.

Monitoring

We have extensive experience of installing, maintaining and measuring monitoring systems to detect movement in dams, rail lines and tunnels, roads, runways and other structures.
Points can be monitored by total station, digital level or GPS.

Leica GeoMOSS software may also be employed, combined with remote total stations and other sensors, to provide 24-hour real time monitoring. See also Advanced Services for Monitoring.

Obstruction Surveys

We have completed numerous obstruction or obstacle surveys for both military and civilian airports in the UK and overseas. Surveys are completed to the CAA’s CAP 168 and CAP 232 specifications using SmartRover GPS receivers combined with reflectorless laser distance measurement using digital total stations.
Notable surveys have been completed for Heathrow, Gatwick, Stansted and Leeds/ Bradford airports, as well as many military airfields in the UK and overseas.

Setting Out

Fully equipped setting out teams can be provided to work in the construction environment, experienced staff use total stations and levels to set out coordinates, points or lines from supplied CAD drawings.
