Service details
What Geotechnical Soil Investigation covers
Use this section to check whether the service matches your project. It sets out the typical scope, inputs, deliverables and controls; the signed appointment defines the final responsibility.
Who is this service for?
Project owners, consultants, contractors and institutions use this service when they need field investigation and reporting that turns ground-condition information into usable evidence for foundation and construction decisions. Start with site plan, proposed building or infrastructure information and known loading conditions. and access permission, utility information, previous reports and site history..
What does SMCTi deliver?
Typical deliverables are investigation plan and location schedule.; borehole or trial-pit logs, sample register and field test records.; laboratory test coordination and results register.. The project brief and appointment confirm which items apply.
How does the Geotechnical Soil Investigation process work?
SMCTi starts by define the investigation objective, proposed loads, foundation questions, access constraints and required reporting format. It then review available survey, geological, previous investigation and site-use information to set the investigation plan. and set out investigation points, confirm utility clearance and mobilise the approved equipment and competent field team.
What affects the scope and result?
Scope depends on the approved documents, site or asset conditions, access, authority requirements, programme and appointed responsibilities. Final structural or foundation design, environmental contamination assessment and specialist geohazard studies require separate appointment unless included.
How does SMCTi control quality?
Investigation points, depths, samples, tests and groundwater observations are logged consistently and traceably.
Why choose SMCTi
Why choose SMCTi for Geotechnical Soil Investigation?
Choose SMCTi when the investigation must answer a foundation decision, not merely produce borehole logs.
A generic drilling programme can collect data without resolving the actual design question. SMCTi starts with the proposed structure, loads, site history, access and decision required, then connects field records, laboratory results, interpretation and stated limitations in one usable report.
The practical difference
- Investigation points, depths, sampling and tests are selected around the project decision and available site evidence.
- Measured field and laboratory results are kept distinct from engineering interpretation, assumptions and recommendations.
- Locations, samples, groundwater observations, refusal conditions and test results remain traceable from fieldwork to report.
The SMCTi difference is decision-grade ground information: clear evidence, clear interpretation and clear limits on what the investigation can establish.

Field investigation and reporting that turns ground-condition information into usable evidence for foundation and construction decisions.
Discuss this serviceDefine the investigation objective, proposed loads, foundation questions, access constraints and required reporting format.
Review available survey, geological, previous investigation and site-use information to set the investigation plan.
Set out investigation points, confirm utility clearance and mobilise the approved equipment and competent field team.
Carry out drilling, sampling and in-situ testing with depth, recovery, groundwater and refusal conditions recorded.
Coordinate laboratory testing, check data completeness and distinguish measured results from engineering interpretation.
Issue a report that states methods, logs, test results, assumptions, limitations and recommendations for the decision required.
Scope of work
- Investigation planning based on the proposed structure, site history, ground profile and decision required.
- Boreholes, sampling, in-situ testing, groundwater observations and field records as agreed.
- Laboratory testing coordination and interpretation of available field and laboratory results.
- Geotechnical reporting with factual findings, stated limitations and recommendations within the appointed role.
Client inputs required
- Site plan, proposed building or infrastructure information and known loading conditions.
- Access permission, utility information, previous reports and site history.
- Required design decisions, reporting standard and review or approval requirements.
Typical deliverables
- Investigation plan and location schedule.
- Borehole or trial-pit logs, sample register and field test records.
- Laboratory test coordination and results register.
- Factual and interpretive geotechnical report with limitations and recommendations.
Quality, safety & control
- Investigation points, depths, samples, tests and groundwater observations are logged consistently and traceably.
- Testing is specified and reported against the agreed project requirements and competent laboratory procedures.
- Recommendations state the information basis, uncertainty and limitations; they are not presented as a substitute for final design responsibility.
Assumptions & exclusions
- Final structural or foundation design, environmental contamination assessment and specialist geohazard studies require separate appointment unless included.
- Access permissions, utility clearance and safe working conditions must be available before fieldwork starts.
