At Cognition Land and Water, we pride ourselves on being an environmentally friendly and conscious company with a deep focus on the sustainability of our work.Read more
With a team of experienced and highly qualified professionals in our project planning and management team, Cognition is adept at taking your project through all stages from concept, feasibility and due diligence through to value engineering, design and regulatory approval and on to implementation, project management and completion. Our ISO9001 accredited Integrated Management System provides us with the tools to deliver your project effectively and efficiently, on time and within budget, to the quality you expect from Cognition Land and Water.
Cognition has an enviable track record of successfully negotiating approval of permit and licence applications with the Environment Agency, local authorities and other regulators. Whilst the majority of our team are contractors ‘born and bred’, a significant proportion of our senior management have specialist skills and backgrounds that lend themselves to successful regulator negotiation. For example, our Operations Director has some 20 years’ experience working within the Environment Agency and has an in-depth knowledge of the organisation and how it operates. In addition, our Technical Director has almost 30 years’ experience working for engineering and environmental consultancies and understands their key drivers and demands.
Through the regular work we carry out in contamination remediation, earthworks and enabling works, Cognition is very familiar with obtaining approvals for Mobile Plant Permits, Materials Management Plans under DoWCoP, discharge consents (to ground and sewer), Deposit for Recovery Environmental Permits, Standard Rules and Bespoke Environmental Permits, etc.
The sustainable management of soils is a key driver for Cognition Land and Water. Undoubtedly, the greatest impact we can make in terms of cost, programme, sustainability, waste minimisation and carbon reduction is the proactive, systematic and meticulous management of site won soils.
Specialist processing, picking and screening; biological and chemical treatment; stabilisation and solidification; rigorous tracking and segregation of stockpiles - all of these approaches lead to very significant reduction in unnecessary disposal to landfill with resultant savings in costs, tax and the loss of valuable materials resources. We regularly achieve reuse or recycling of over 95% of previously marginal and contaminated soils on our projects.
This is such an important issue for us that Cognition is a lead funder and Project Steering Group member for an upcoming CIRIA guide into the Sustainable Use of Surplus Soils and Aggregates on Construction Sites. Being at the forefront of industry best practice gives us a valuable edge over our competition and enables us to offer cutting edge approaches and methodologies to our clients.
Cognition offers a turn key project management service from start to finish where we take on a project for a developer and carry out approvals, enabling works, groundworks followed by organising all the follow on trades. We manage these trades to completion of the whole build and handing over the completed properties to ensure we meet the developers budgets and programme deadlines.
