In preparing a preliminary route map, survey data needs to be gathered in order to produce construction alignment sheets, permit drawings, easement plats and engineering detail design drawings. An as-built survey should be carried out during construction of the pipeline so that the exact location of the pipe can be recorded and the data used to prepare the final as-built drawings.

Merrett Surveys professional surveyors have vast experience in pipeline surveys and use the latest technology, including EDM total stations, double depth pipeline detection equipment, GPS and terrestrial laser scanning. Our experienced surveyors gather survey information and record attributes such that they can be used in any CAD and GIS programs.

We provide:

• GIS asset data collection surveys to aid in determining the route of a new pipeline.
• Airborne LiDAR surveys to collect wide area topographic terrain maps.
• Boundary and topographic surveys.
• As-built surveys and stake out for construction.
• River crossing profiles to monitor erosion rates etc...for hydrographic modelling.
