What is Soils Investigation?
Soils investigation is a critical step in any pre-construction and addition/renovation projects. It involves the assessment of subsurface conditions through field sampling and laboratory analysis to determine whether the site can support the proposed structure. The process helps identify soil composition, strength, density, and moisture levels, etc. —information necessary for proper foundation design and regulatory compliance.
At QAI-HGEI, we offer a full range of geotechnical and soil testing services, including engineering geology and construction site evaluation for clients in both public and private sectors. Our experienced field crews and laboratory personnel utilize advanced equipment and methods to provide timely, accurate, and detailed data for engineers, architects, and developers.
Our Soil Investigation Process Includes:
Site reconnaissance and planning
Borehole drilling, test pit excavations, soil sampling and logging
Laboratory testing for soil classification, compaction, permeability, and strength
Comprehensive reporting with geotechnical recommendations
Liquefaction Analysis based on site-specific conditions
All testing is backed by expert consultation and detailed reporting to support your engineering and quality goals.
Why is Soil Testing Important?
Proper soil testing minimizes construction risk by identifying subsurface issues early. It ensures foundations are designed based on actual site conditions, prevents costly structural failures, and supports compliance with local and national building codes.
QAI-HGEI’s combination of expertise, accredited facilities, and client-focused service makes us the ideal partner for soils investigation and geotechnical engineering evaluations.
