Our client operates Nottingham County Council’s green waste composting facility. The green waste material (non-food waste) is turned into a fertile compost that is used by farmers, garden centres and households. The existing facility was at capacity and required modernisation.
Our brief was to upgrade the facility to a modern, high tech and energy-efficient plant under a design and build contract. The project required close liaison with the Dutch company WTT who supplied the aeration equipment and technology.
Taking green waste out of the landfill disposal stream has a huge benefit to the local population and environment alike. Recycling in this way also reduces the strain on local and world habitats, greenhouse gas emissions and chemical interventions that can adversely affect watercourses and biodiversity.
As a sustainability-focused business, we designed into the construction process ways of reducing our impact on local people, the environment and future maintenance. Measures taken included using gas and solar power for temporary accommodation, recycling all the excavated materials to eliminate the need for landfill and associated transportation costs, batching 90% of the required concrete at the site to reduce road congestion and transportation emissions. The batching was part of overall energy and time-efficient concrete laying strategy using alternative and fast concrete laying technologies.

Converting waste collection vehicles from diesel fuel to Compressed Natural Gas (CNG) as part of our client, and the London Mayor’s, drive to reduce harmful vehicle emissions in and around London, England.
We were appointed to design and build the CNG refuelling stations infrastructure and facilitate the equipment installation.
Converting vehicles from diesel to less polluting fuels such as CNG improves the public and workers’ air quality and is proven to reduce early deaths. The construction process was developed through design to minimise its environmental impacts by minimising excavations, off-site disposal and utilising recycled materials.

This old engineering facility had been empty for some time. Our client was required to carry out an environmental audit that established a historic oil spill at some point in the past. The oil was found below ground and floating on non-aquifer and trapped localised water.
We were appointed to carry out the civil works involved in installing a cleverly designed pump and treatment process. The traditional excavate and landfill option would have cost in excess of £700k and had a big impact on the local environment.
It is important that the industry addresses historic practices that have an adverse impact on the local environment and that could affect future generations and habitat alike. This treatment process was a clever way of minimising the disturbance of existing land and building surfaces and could be likened to modern-day keyhole surgery. The innovative design reduced the civil engineering infrastructure requirements, energy usage, emissions, transportation, and landfill need by siphoning off the underlying oils that could then be recycled and put back to use in the local economy.

This was a disused industrial site that had produced wood preservatives. The manufacturing processes had contaminated the groundwater and soil with various hazardous chemical contaminates; chemicals included chromium, cadmium, arsenic and fuel oils. In addition, the old industrial and office buildings also contained extensive fibrous asbestos.
Our client’s instructions were to investigate and profile-map the areas of contamination, review with various government authorities, agree on a clean-up strategy and to undertake the necessary works for the sale of the property.
We reviewed the brief from the perspective of meeting statutory requirements; protecting future site users and developments, keeping the workforce safe and minimising the carbon footprint and expenditure of the remediation process and future redevelopments.
