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
Cognition Land and Water is not a site investigation contractor and we do not regularly carry out site investigations as a single service on a project. However, through the vast experience and track record of our professional team, including several who have worked within ground investigation contractors and consultants for many years, we are adept at planning, specifying and managing site investigations for projects where we have been commissioned to carry out our ground engineering and/or remediation contracting services. This may include additional desk study research, supplementary ground investigation following gap analysis, ground investigation to finalise detailed design, additional investigation to refine our approach or solution to a project, installation of additional gas/ groundwater monitoring wells, or investigations into unforeseen ground conditions during a project.
Our in-house staff and plant resources makes the execution of ground investigations cost effective and rapid for our clients. Strong relationships with our network of specialist ground investigation contractors means that we can bring in these specialist services on larger investigations using a wide variety of techniques and technologies.
Cognition regularly and successfully collaborates and negotiates with local communities, local authorities, the Environmental Agency and other regulators. We constantly monitor changes and updates to environmental regulation and legislation and adjust our internal procedures and practices accordingly. Several of our employees have worked in the past with regulators including the Environment Agency. Hence, we have in-depth knowledge and experience of the objectives, drivers and touch points of regulator stakeholders.
Cognition uses various manual and automated monitoring systems to control emissions of volatile compounds, dust and odours from all our site activities and deploy suitable measures and controls to mitigate these before they become a nuisance or a potential risk. For daily monitoring Cognition uses a mix of active, dust monitoring units (Turnkey OSIRIS), active VOC monitoring sensors (Turnkey iGas) as well as passive, dust deposition pots, manual PID and odour observations. The AirQWeb system allows us to view, download and generate data reports as well as share live data with our clients. We exclusively use UKAS accredited laboratories for all sample testing.
Asbestos air fibre reassurance monitoring is undertaken by an independent UKATA accredited specialist contractor during all asbestos remedial activities undertaken by Cognition. Monitoring includes site boundary, close proximity around the processing area as well as personal monitoring of the most susceptible site staff.
Cognition conducts various groundwater and surface water monitoring as part of our obligations under mobile plant permit as well as requirements of site-specific environmental permits and site operations. This is managed and carried out by our team of trained and competent site engineers who also have the experience and skills to conduct site investigations, monitoring well installations and decommissioning.
Cognition is committed to reduce noise and vibration levels from all site activities by using modern and well maintained plant and equipment avoiding excessive noise and minimising vibration. All our equipment and activities are fully compliant with the recommendations set out in BS 5228-1&2:2009, Code of Practice for Noise and Vibration Control on Construction and Open Sites. We monitor our activities daily using a mix of manual and automated active monitoring equipment.
We carefully plan and actively assess potential hazards and resultant risks of all our operations. This informs our decisions regarding all aspects of our works such as our approach to the required works, access, transportation, selection of equipment, site logistics and mitigation measures to minimise the risk to site staff and surrounding receptors such as local community or the wider environment.
With substantial recent investment in sustainable technologies, materials, plant and equipment, Cognition is now in the process of implementing ISO 14001 and ISO 45001, both of which will strengthen our systems and performance and reinforce our past efforts in establishing ourselves as a Net Zero Carbon company.
