Topographical Surveys

Purpose

A topographical survey produces a three-dimensional model of a piece of land. It includes all natural and man-made features (e.g. trees, buildings, roads, footpaths, manholes, utility poles, retaining walls etc.) represented on the drawing by text, lines and symbols.
It also includes heights and elevations, represented on the drawing by spot levels and contours.

The survey then provides a base map for the design of a proposed development. JM Surveys can provide any output a client requires, whether it be a 2d or a 3d drawing, linked to any co-ordinate system (e.g. local grid, ITM, Irish Grid 1975 etc.) and to any datum (e.g. site datum, Malin Head etc.).

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.

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.
