Survey Audits & Check Surveys

Independent verification of survey work and underground workings — the impartial second opinion that protects safety, compliance and the value of what's been built.

What it is

Survey Audits & Check Surveys — engineered for accuracy.

A check survey is an independent re-measurement that confirms — or challenges — the accuracy of survey work, whether done in-house or by a contractor. Survey House performs this auditing function for new mines and as third-party checks on existing surface and underground workings, acting for either a client or a contractor.

The cost of getting it wrong is real: the company has seen a hoist chamber and main shaft set out in the wrong place, where rectification and contract extension were estimated at around R14 million per month over six months. Independent control surveys are essential to maintaining the accuracy of an underground network, whose bearing can drift over time if left unchecked.

The work includes re-observing and adjusting control networks, verifying setting-out and as-built positions against plan, checking primary bearings with gyro observation, and confirming statutory survey records and plans. On the Mine Audit & Consulting side, a surveyor on the shaft offsets for over- and under-break before each blast — assurance that protects management, regulators and partners alike.

FAQ

Survey Audits & Check Surveys — frequently asked questions

Clear answers to the questions clients and search engines ask most about this service.

What is a check survey?

An independent re-survey that verifies the accuracy of existing survey work or workings — re-observing control, setting-out and as-builts to confirm they are correct, or to identify and quantify discrepancies.

Why commission an independent survey audit?

To get impartial assurance that survey-critical work is accurate before errors cause a mis-holing, a statutory non-compliance or a disputed measurement. A single mis-set shaft has cost an estimated R14 million per month to rectify — independent checking is cheap insurance against that.

Can you audit a contractor's survey?

Yes — Survey House acts as an independent third party for both clients and contractors, auditing survey work, control and records, and can also establish survey offices and systems on new operations.

Do you help with mining-licence survey requirements?

Yes — the company has supported clients through licensing and compliance, including setting up survey systems and auditing on greenfield projects such as Great Basin Gold's Burnstone.
