Volumetric Surveys

JM Surveys carries out volumetric surveys with GPS and total station to produce an accurate three-dimensional model of stockpiled material or excavated quantities from a borrow pit. These surveys are essentially a variation of topographical surveys, with particular emphasis on levels and breaklines.
The information presented on the drawing includes contours, spot levels and quantities calculated in cubic metres.

JM Surveys uses a combination of high precision GPS and total station with dedicated mapping software to produce the required outputs. Volumes are calculated at the processing stage along with any other necessary information (i.e. average fill/cut).
‘Before and after’ surveys can be compared to give rapid and reliable earthworks quantities.
Drawings can be supplied in Irish Transverse Mercator (ITM) or Irish National Grid.

Application

Calculation of the quantity of material to be excavated off site or imported on site.
Calculations for planning permission for soil infill recovery sites.
A smooth base surface for a stockpile will allow accurate volume determination.
Ground surveying is possible in any weather conditions.
Quantify amount of material removed from excavations and quarries.
Accurate calculation of capacity of dams and the amount of airspace remaining in landfills.

Topographical Surveys

A topographical survey produces a three-dimensional model of a piece of land.

Floor Plans &
Elevation Surveys

Floor plans of an existing building are produced by a total station with a built in laser, disto (laser measuring device) and a hand-held computer which stores the data later used to generate the drawing.

As-Built Surveys

An as-built survey drawing is a mapped record of a completed project or development, and is usually required before a Local Authority takes a development in charge.

Forensic Surveys

JM Surveys carry out forensic surveys for forensic engineers all over Ireland.

Boundary Surveys

JM Surveys carries out boundary surveys for various legal purposes.

Setting Out Surveys

Once an architect or engineer has prepared an accurate plan of a proposed development we can then set out roads, buildings, services, boundaries etc. with pegs on the ground.
