Land Quality & Regeneration

CONTACT US
Sustainable Development and Brownfield Site Regeneration

We offer a fully integrated geotechnical and environmental consultancy, providing a wide range of services from initial feasibility studies and investigations to the design, management, supervision and validation of remediation projects. With expertise in a range of disciplines, our geo-environmental staff work together to assess the natural and anthropogenic issues relating to site conditions within the context of a proposed or existing development.

Contaminated Land Consultants
With over 20 years in the contained land sector, Ayesa has extensive experience in providing practical solutions to our client's brownfield site issues. Developers of brownfield sites across the UK face the challenges of an industrial legacy and our aim is to adopt a collaborative approach with clients to understand the feasibility, opportunities and constraints in relation to the regeneration of a brownfield site.  Contaminated Land is a field with strict legislative standards and we assist with initial site appraisals to master planning to optimise land value and discharging planning conditions.

Advice Across all Stages of Brownfield site projects
Our technical advice, risk assessment and appropriate mitigation can help you find a cost-effective and safe solution that meets statutory requirements. We assist developers to resolve the contamination issues that increase risks and add uncertainty to programme, costs and schedules. Our teams have delivered services at every stage of contaminated land management from initial due diligence and desk study through to investigation, risk assessment, remediation and post-completion monitoring. Our team understands the regulatory frameworks surrounding contaminated land and land quality issues in different jurisdictions. We take a pro-active approach working with regulators to achieve solutions that satisfy legal requirements while minimising delays to development projects.

Our consultants are adept in the preparation and completion of Conceptual Site Models (CSMs), undertaking environmental risk assessments following the source, pathway, receptor model and developing remedial options.  With an excellent working knowledge of the planning regime and contaminated land legislation, our team are able to provide guidance and support to clients through all aspects of development from the pre-planning stage through to the discharge of planning conditions.

Large and Small Brownfield Projects
Our consultants have a wide range of experiences from small scale residential developments through to large-scale commercial and industrial projects. In partnership with experienced contractors, we deliver a fully coordinated ground investigation, remediation or earthworks programme to comply with regulatory requirements in both the planning and legislative frameworks. When you work with Ayesa, we combine our geo-environmental, geotechnical, environmental and structural engineering services to deliver an integrated cost-effective approach with a lens on sustainability.
