Geo Environmental / Technical

Assessing land quality is essential before development, sale or redevelopment. We deliver contaminated land assessments across residential, commercial and industrial sectors, including Phase I desk studies to identify risks to people and the environment.

Geo Environmental

Our Geo-Environmental Engineering services support the identification, assessment and management of land contamination and ground-related environmental risks.

We help clients understand the hazards and risks posed by land to both people and the surrounding environment. We then provide solutions that meet the requirements of regulatory bodies, satisfy stakeholder expectations, and align with the specific needs of each project.

We deliver Phase 1 and Phase 2 site investigations, contaminated land assessments and hydrogeological risk assessments, providing clear, proportionate advice to support planning, regulatory compliance and the safe redevelopment of complex sites.

Phase 1 Environmental Desk Study / Preliminary Risk Assessment

We undertake Phase 1 Environmental Desk Studies to identify potential contamination risks and inform early project decisions.

Phase 2 Geo-Environmental Site Investigation Report

Our team delivers Phase 2 investigations to characterise ground contamination and assess risks through targeted sampling and analysis.

Contaminated Land Assessment

We carry out contaminated land assessments to evaluate pollutant linkages and determine appropriate risk management measures.

Hydrogeological Risk Assessment

We prepare hydrogeological risk assessments to evaluate groundwater impacts and protect controlled waters during construction and operation.

Geo Technical

Our Geotechnical Engineering services provide robust ground risk assessment and design support from feasibility to construction. We deliver geotechnical desk studies, ground investigation specifications, factual and interpretative reporting, and outline to detailed geotechnical design, enabling safe, compliant and cost-effective foundations and earthworks solutions for complex ground conditions.

Our geotechnical engineers provide the insight needed to understand your ground conditions and ensure your project is built on a solid foundation, our services include:

Geotechnical Desk Study Report (GDSR)

Our team produces a Geotechnical Desk Study Report to identify ground risks, constraints, and opportunities supporting safe, efficient infrastructure design.

Ground Investigation (GI) Specification

We prepare a Ground Investigation specification defining investigation scope, methods, and testing to characterise site ground conditions.

GI Factual and Interpretative Reports

Our team compiles factual and interpretative reports to present ground data and assess its implications for design.

Geotechnical Design Reports (outline and detailed)

We deliver outline and detailed geotechnical design reports setting out analyses, assumptions, and recommendations for safe construction.

Frequently Asked Questions

What is a Flood Risk Assessment (FRA)?

A Flood Risk Assessment checks if a site is suitable for development by evaluating its risk of flooding. Requirements vary by region, but usually depend on the site’s location, size, and type of development. In England and Scotland, it’s called a Flood Risk Assessment; in Wales, it’s a Flood Consequence Assessment.

Do I need a Flood Risk Assessment?

A Flood Risk Assessment is typically required when any of the following applies:

1. The site is over 1ha.

2. Can be classed as a major development.

3. Located in Flood Zone 2 or 3.

4. Drainage area is classed as critical.

Do I need a Drainage Strategy?

A Drainage Strategy (SuDS report) is needed if your site is over 1ha, a major development (10+ units), in Flood Zone 2 or 3, in a critical drainage area, or if building a new structure.

Local planning authorities may request one to ensure your project complies with regulations and avoids future issues. Checking early helps prevent delays, and our team can guide you through the process.

We have already carried out an FRA but are now being asked to provide further information? E.g. modelling

In certain areas the LLFA, EA, SEPA or NRW may not hold sufficient information for your site to inform their decision on flood risk, flood sources and flood hazards. We can support your Flood Risk Assessment in-house with hydrology assessments and detailed hydraulic modelling.

What is involved with hydraulic modelling?

Hydraulic modelling simulates how water behaves under changing conditions to assess flood risks. Using software such as MIKE FLOOD, Flood Modeller Pro, TUFLOW, and HEC-RAS, we predict flood depths, velocities, inundation rates, and hazard ratings. These insights inform UK flood maps and help clients develop effective flood management strategies.
