We offer a full range of high-precision surveying and measurement services, from alignment and deformation monitoring to complex infrastructure mapping. Our commitment to advanced technology and expert techniques ensures reliable, accurate results that meet the demands of every engineering project.
TUNNEL SURVEYING & NAVIGATION
- Structures layout.
- Precise alignment marking.
- Navigation system equipment installation and pre-advance guidance system calibration.
- Tunnel Boring Machine (TBM) guidance and navigation during tunnelling and attendant quality control surveys.
- We offer TBM guidance for tunnels from 900 mm ID and above.
SETTLEMENT | GEOTECHNICAL MONITORING
- We install necessary the geotechnical and geodetic instrumentation.
- We opt for remote continuous monitoring of all equipment and emanating data where possible.
- We provide geotechnical and optical measurements reports on response to stress of structures and existing ground.
CONTROL NETWORKS
- Pre-analysis, design and optimization of geodetic networks, adjustment and post analysis of geodetic measurements.
- Pre-analysis and design of the geometry of a project geodetic network and report on necessary measurements required to optimize accuracies to support project requirements.
- Analysis and optimal configuration of a site survey network given the space and geometrical limitations of a construction site.
- Perform regional geodetic horizontal and vertical networks using GNSS receivers, precise total stations and spirit levels for governments and large agencies.
AS-BUILTS
- As-built surveys of existing structures during and post-construction; comparison to design.
- We have performed accurate as-built surveys for pipes as small as 300 mm ID.
