Surveying services and supervision
for mining projects
How much does an error cost when it is found after it has been built? Rework, claims and weeks of delay. We know where these problems tend to appear in a mine expansion and what the Projects team needs to decide in time.
T&S Ingeniería has provided surveying services for mining and infrastructure throughout Peru since 1998: topographic surveys, stakeout, construction control and survey supervision of contractors.
We know what matters to your project
Any calibrated instrument can measure. In mining surveying, the value lies in knowing what to measure, when and why: the critical tolerances for assembly, the quantities to verify before progress billing, and the work front that can delay the next one. That judgment comes from 28 years inside operating mines in Peru.
Survey supervision that improves everyone's work
Having everyone work on the same reference is the starting point, not the goal. Our aim is for each contractor to improve their processes: fewer costly errors, fewer delays, and quantities that match what was actually built and are properly supported.
We anticipate problems, explain the reasoning behind each observation and support the teams until the process is corrected. The project's success is shared.
What we do on your project
- Contractor survey supervision and quantity verification.
- Topographic surveys for studies, engineering and technical files.
- Stakeout of axes, levels and structures according to design.
- Survey control of earthworks progress: cut and fill volumes.
- Dimensional control of electromechanical assembly.
- As-built survey and release protocols.
- Project coordinate system and transformation set.
Independent survey supervision
When several contractors work at the same time, we independently verify their measurements and progress, so the Projects team has a single reliable source of information before releasing each stage.
A real case
In 2014 we took part in supervising the construction of the Las Bambas tailings dam, in Apurímac. We have kept working at that operation ever since: today it is the client with the most projects in our history.

Frequently asked questions
Who do you work for?
For the mine's Projects team and for engineering and construction companies carrying out expansions inside operating mines.
Do you carry out topographic surveys for studies and technical files?
Yes. We carry out topographic surveys with total stations and GNSS and, when the area justifies it, with aerial LiDAR, for studies, engineering and technical files for mining projects in Peru.
What if the mine uses a local coordinate system?
We integrate it: we measure the points in both systems and document the transformation, so every contractor works on the same reference.
How much does a surveying service cost?
Each service is quoted to fit the needs of the project: the price depends on the technical specifications, site conditions and scope. We review your requirements and, when needed, make a technical visit before quoting.
How long does a topographic survey take?
It depends on the specifications, site conditions and scope. With that information, we propose a schedule together with the quote.
What do you need to quote?
Location, scope (stakeout, construction control or supervision), estimated duration of the works and number of work fronts. Write to comercial@grupots.com or call +51 967 421 477.
A project is built only once. At T&S Ingeniería we bring our experience so that every stage is built right the first time.
