Mining, Site & Building Surveys

Precise measurement, volume calculation, setting-out and construction control across mining sites, construction sites and building projects.

Mining sites and construction sites are constantly changing. Every cubic metre excavated, filled or stockpiled is both a cost and a measure of progress. The way to track that change reliably is to survey the site at regular intervals and compare it with its previous state.

A volume figure is the difference between two surfaces: the surface at the date of measurement and the reference surface. Its accuracy therefore depends on both measurements sitting in the same coordinate system. That is why permanent control points are established on site — if the reference moves, so does the volume.

On building work, surveying runs ahead of construction. Axis and level setting-out is done before the pour; verticality and geometry checks are done during or immediately after. Catching an error early is far cheaper than correcting it later.

How We Work

Process

  1. Reference network

    Permanent control points are established on site and tied to the national coordinate system; every periodic survey rests on this network.

  2. Baseline survey

    The surface is measured before work begins. All subsequent volume calculations are made against this reference.

  3. Periodic survey

    The site is resurveyed at agreed intervals; drone photogrammetry covers wide open areas, the total station covers narrow and deep sections.

  4. Volume calculation

    The difference between the two surfaces is split into cut and fill; results are reported as tables and a colour-coded difference map.

  5. Reporting

    The period report, cumulative progress and the current site model are delivered.

FAQ

Common questions

How often should volume surveys be carried out?
Usually in line with the payment certificate cycle; on sites billed monthly, a monthly survey is common. Fast-moving excavation may call for weekly surveys. What matters is not the interval itself but that every survey sits on the same reference network.
Is drone-based volume calculation reliable?
On open, visible surfaces yes — supported by ground control points it delivers centimetre-level accuracy. Lower levels, galleries and covered areas outside the line of sight still require conventional surveying.
What is an as-built survey for?
It documents where the construction actually is relative to the design. It is used both in acceptance processes and so that subsequent work can be set out from a correct reference.
How is verticality checked on a high-rise?
From control points established outside the building, the position of column and shear wall axes is measured with a total station on each floor and the deviation from the design position is reported.
