- A site laboratory (all rights reserved)
The site laboratory is equipped for performing analyses and ground tests which will be needed at 2 stages in the operations:
• At the preparatory stage, to identify the types of ground and their characteristics.
These provide the site engineers with information on how they should be excavated, used and compacted.
• At the utilisation and construction stage, to ensure that this has been properly carried out and will ensure the structural durability.
To do this, the laboratory technicians employ standardised tests with methods and test equipment that are fully and precisely specified so as to perform tests that are reproducible and comparable.
A traditional site laboratory is fitted out to perform around ten different analyses, such as soil granulometry, water content, degree of clay plasticity, and rock friability.
Physical characteristics tests relate to the soil compaction capacity and its capability of taking site traffic: density measurements, mechanical resistance measurements, and measurement of load bearing capacity.
Every excavation and every infill operation is therefore subject to a wide range of tests which give full traceability of the materials used and quality control of the engineering operations undertaken.
