Precise Surveys for Projects Without Surprises
At PG Arpentage, we lay the foundations of your projects with a precision that eliminates costly surprises. By combining multigenerational expertise, cutting-edge technologies, and an absolute commitment to health and safety, we ensure the reliability of your work from the very first step.
Our teams of qualified technicians work in compliance with the highest industry standards and deliver impeccable surveys that allow your job site to move forward without delays, without surprises, and by the book. Every measurement counts, every data point is verified, and every deliverable reflects our pursuit of excellence.
Topographic Surveys
Complete terrain surveys to determine existing elevations, slopes, and features, which are essential for the planning and design of any project.
Our teams use robotic total stations and high-precision GPS systems to map your site with millimetre-level accuracy, establishing the solid foundations your project needs.
Layout
PG Arpentage offers layout services for infrastructure projects, as well as mechanical, structural, roadway, and civil engineering layout, ensuring placement that conforms to plans and specifications. We also carry out critical layout work where absolute precision is essential, particularly for structural axes, foundations, underground networks, and prefabricated elements.
Through rigorous tolerance control and close coordination between teams, we minimize the risk of errors, rework, and delays, thereby contributing to the quality, safety, and smooth operation of job sites.
Civil Engineering Work
Site grading, as well as the layout of concrete structures, curbs, and flat surfaces, ensures durable development that conforms to plans. We also offer the layout and surveying of piping networks to guarantee their position, slope, and on-site compliance.
Through the use of precision electronic levels, GPS systems, and total stations, we achieve very tight tolerances, even on the most demanding job sites, whether for sanitary, stormwater, industrial, or underground networks.
Quality Control and Assurance
Systematic, rigorous verifications to ensure that every phase meets the tolerances and requirements of the project.
Our quality assurance protocols rely on calibrated equipment, proven procedures, and careful interpretation of plans and specifications to deliver compliant results every time. We identify discrepancies and produce detailed deviation reports.
Tunnel Control and Alignment
Specialized measurements to guide and verify the alignment, positioning, and precision in tunnel construction. Using our high-precision total stations, we ensure millimetre-level monitoring of underground excavations and guarantee compliance with tolerances in the most demanding environments.
High-Precision Surveys and Control Networks
Installation and maintenance of reliable reference points to guarantee measurement accuracy throughout the job site. We establish robust control networks using our high-precision total stations and GPS equipment, with geometric levelling and geodetic surveys that conform to local authority specifications.
These networks ensure consistency among all stakeholders on site and allow for the verification of the correlation between the terrain and its model.
Industrial Layout
The positioning and marking of massive industrial equipment demands absolute rigour. Our teams intervene to precisely lay out your machine tools, production equipment, turbines, conveyors, tanks, piping systems, and any machinery critical to your operations.
We establish reference benchmarks, verify foundations, mark anchor points, and validate compliance before final installation. Every measurement is carried out to strict tolerances to avoid readjustment costs.
Industrial Alignment
Our technicians use high-precision laser systems and total stations to measure, analyze, and correct misalignments that cause premature wear, excessive vibrations, and energy losses.
We intervene on your pumps, compressors, turbines, motors, reducers, and any machinery requiring millimetre alignment. Verifications are carried out according to industry best practices to reduce unplanned downtime.
Site Monitoring
Our teams maintain a strategic presence on your job sites to verify that work complies with plans and specifications.
We analyze field data in real time, rapidly identify discrepancies, and work with your teams to adjust interventions before problems escalate. This proactive monitoring guarantees compliance with tolerances, schedules, and safety standards, while reducing the risk of costly rework.
