Ground Investigation Service
Coordinate ground investigation inputs for foundation and testing decisions.
- Fully Insured
- Commercial & Site Work Specialists
- 5 Star Rated
- Emergency Callout
We arrange and interpret ground investigation inputs so the foundation strategy is based on real site conditions rather than assumptions. That supports foundation design, testing and buildability decisions.
How ground investigation is engineered and delivered
Ground investigation reduces uncertainty before foundation, pavement, drainage or remediation design is fixed. A useful investigation is scoped around project decisions: the expected loads, development layout, suspected hazards, groundwater, contamination and the parameters designers actually need.
Engineering workflow
Stage 1
Desk study and decision mapping
Review site history, geology, previous reports, proposed development and designer information needs so fieldwork targets specific risks rather than collecting generic data.
Output: Investigation scope, rationale and location plan.
Stage 2
Fieldwork coordination
Coordinate specialist trial pits, boreholes, probing, sampling, groundwater observations or in-situ tests with access, service clearance and reinstatement.
Output: Field logs, samples and factual observations.
Stage 3
Testing and interpretation
Send scheduled samples for appropriate laboratory testing and interpret strata, strength, settlement, groundwater and contamination information against the proposed works.
Output: Factual and interpretive reporting with design parameters and limitations.
Stage 4
Design and procurement handover
Translate findings into foundation, earthworks, drainage or remediation decisions and identify residual risks that tenderers must allow for.
Output: Design-risk briefing and procurement information pack.
Planning, constraints and ground risk
Planning considerations
- The investigation depth and spacing should reflect the structure, earthworks and drainage decisions to be made.
- Utility clearance, access, working areas and reinstatement affect where exploratory points can be completed safely.
- Groundwater often needs repeat observation; a single visit may not describe longer-term conditions.
- Contamination and geotechnical sampling have different objectives and should be coordinated deliberately.
Site constraints
- Live sites, buried services and limited drilling access
- Occupied buildings requiring low-disruption exploratory methods
- Contaminated arisings, groundwater and sample handling
- Reinstatement of slabs, roads, gardens or operational areas
Ground conditions
- Made ground can vary sharply across short distances and may contain obstructions or contamination.
- Clay strength and volume-change behaviour influence shallow foundations and earthworks.
- Granular soils and groundwater affect excavation stability, drainage and dewatering.
- Historic workings, filled ground or buried structures require targeted investigation rather than assumptions.
Procurement and project preparation
Procure investigation against a project-specific scope with clear factual and interpretive outputs. State who designs the investigation, clears services, provides access, schedules laboratory testing, assesses contamination and converts results into structural or civil design.
Tender checklist
- Proposed development, loads and current layout
- Desk-study findings and known site-history risks
- Exploratory methods, depths, locations and sampling schedule
- Laboratory and in-situ test schedule
- Reporting format, design parameters, contamination and groundwater scope
Prepare before mobilisation
- Issue the proposed development layout and the decisions the report must support.
- Provide utility records and arrange site clearance before intrusive work.
- Identify access, working-hour and reinstatement requirements.
- Agree laboratory schedules and reporting deadlines with the design programme.

Frequently Asked Questions
What makes a ground investigation suitable for foundation design?
It must investigate the relevant footprint and depth, identify strata and groundwater, obtain suitable samples or test data and provide the parameters and interpretation the structural or geotechnical designer needs.
Is a desk study enough before tendering groundworks?
A desk study is an important first stage but does not usually verify site strata, strength, groundwater or contamination. Tender risk reduces when desk findings are followed by targeted fieldwork and testing.
Who interprets ground investigation results?
Interpretation should be completed by an appropriately competent geotechnical or environmental specialist for the relevant scope. Foundation and civil designers then use the parameters and recommendations within their own design responsibilities.
What should be included in a ground investigation enquiry?
Include the proposed development, known site history, required design decisions, access and service constraints, exploratory methods, testing schedule, reporting outputs, programme and responsibility for reinstatement.
Do you coordinate ground investigation with the foundation design?
We work from the ground investigation findings and the engineer's design so the foundation route reflects what the site is actually doing.
