Quarry Surveys

Quarry Surveys can be required for a muliple of reasons such as to ensure work carried out so far complies with planning permission guidelines as outlined under Section 261 of The Planning and Development Act and also for quarry managers to plan for future development of the quarry. We at control surveys can provide such a service by carrying out a complete survey of the quarry showing all buildings, structures, haulage roads, tailings ponds, cliff faces, stockpiles etc and by creating a contour map which show the high and low points of the quarry.  Using a Reflectorless Total Station we can take measurements to inaccessible and dangerous areas of the quarry resulting in a more accurate map without compromising safety. 

Volume Surveys

The information we gather from our surveys allows us to determine volumes.  We can produce a 3D model of a given stockpile and accurately calculate its volume to assist quarry managers in future planning and for stock taking purposes.  Removal of material in quarries can also be monitored.  Contractors blasting and removing the rock in quarries are usually paid by the cubic metre of removed material.  Control Surveys can cost effectively assess the amount removed, thus ensuring both client and contractor are remunerated accordingly. Our mapping software package is very flexible in its approach to volume determination.  Comprehensive reporting, map output, cross-sections etc are a feature of our volume determination and give the client excellent backup and confidence in our results.

Future Planning

Survey maps can also be used by the quarry manager to plan ahead and if a previous survey has been done, to compare what progress has been made in that time. Proposed contours can be created and overlaid on an existing survey map to show how a quarry would look after having had changes made.  To aid visualisation a 3D model and pre and post development cross-sections can be produced anywhere in the quarry showing the existing ground levels compared to the proposed ground levels. Restoration drawings can be prepared, which can be added in an EIS report, to illustrate what the quarry would look like after excavation activites cease. Topographical surveys are also often required by quarries for the proposed development of a new quarry or an extension to an existing one and for legal mapping issues such as area calculation, property subdivision and boundary determination.
