Excavation Base Control
An excavation base control study is an assessment conducted to monitor and evaluate the stability of excavation walls and bottoms or of trenches during construction or excavation work. It helps prevent risks of collapse or instability, ensuring the safety of workers and providing a secure environment for teams working in excavations. It also protects surrounding infrastructure, including buildings, roads, and underground utilities.
OUR METHOD
01
RELEVANCE
Construction Work
During excavation for building foundations, roadworks, underground works, and similar projects.
Trench Excavation
For construction projects involving sewer networks, underground cable lines or other underground utilities.
Site Rehabilitation
During the restoration of contaminated or degraded sites that require excavation as part of remediation work.
02
PROCESS
Initial Inspection
A visual assessment of the excavation walls and base to identify signs of instability, such as cracks, collapses, or settlement.
Geotechnical Measurements
Use of measurement instruments to monitor and record movements or changes in the excavation structure, such as inclinometers, survey piles, deformation sensors, and more.
Analysis and Evaluation
The collected data is analyzed to assess the current stability of the excavation. Comparisons are made against established safety criteria to determine the level of risk.
Continuous Monitoring
Ongoing monitoring is often required to detect any changes in excavation stability over time, particularly during construction phases.
Report and Recommendations
The study results are compiled into a detailed report, which includes an evaluation of current stability, recommendations to minimize risks, and corrective actions if necessary.

INTERPRETATION
OF RESULTS
Adequate Stability
If the excavation is deemed stable, recommendations may include ongoing monitoring to detect any potential changes.
Detected Instability
If stability issues are identified, corrective measures may be recommended, such as reinforcing the walls, adding supports or shoring, or modifying the excavation method.
