Sustainable Development

As a matter of course QuadConsult considers the sustainability of projects through design and is committed to minimising environmental impacts on projects. We have been awarded ISO14001 accreditation for Environmental Management, and are a Member of AECB (The Association for Environment Conscious Building).

Renewable Energy is an important sector for us as we fully believe in its importance for all of our futures.

Entertainment & Leisure

QuadConsult has specialist experience of working with creative teams and construction houses to realise the aspirations of set designers, and also assists the particular needs of the leisure industry.


CDM Support and Principal Designer

QuadConsult has had considerable experience of CDM Regulations since their introduction in 1994, having had many commissions to work as Principal Designer.  We provide CDM advisory services to support clients to discharge their obligations under the Regulations.  In addition, we offer training on the 2015 CDM Regulations, past clients including Natural Resources Wales, Vattenfall and Pure Energy Professionals.

Staff who lead in this role are professionally qualified and have been mentored through training by the Institution of Civil Engineers.



Our engineers review all projects with the client and key designers to assess the geometry and use of building to successfully establish the ideal structural form.

Undertaking all design and detailing our engineers and technicians use the most up-to-date 3D, BIM compliant software.   We regularly undertake projects with carbon zero aspirations, and understand the need for sound sustainable design to achieve accreditations such as BREEAM, WELL, LEED and FITWEL.




By working closely with clients on a diverse range of historically interesting heritage projects, our engineers have acquired considerable experience in traditional construction techniques and sensitive methods of repair for older timber, masonry and iron buildings.

Public Sector

Our commissions for the public sector include many highway commissions including Section 184 and 278 agreements, generally on behalf of housing developers although other clients have commissioned us on wide-ranging projects.

Many strengthening and refurbishment commissions have taken place throughout Wales and England for NHS Trusts, and our engineers have designed several schools, particularly the superstructure for our steel fabricator clients.

As a result of responding to the current unique times in Welsh rail history, QuadConsult has been awarded a four-star RISQS accreditation, and is a primary sponsor under the Sentinel system.  Our team comprises fully rail-safety trained personnel, including experienced technical designers accredited as:

  •    Contractor’s Responsible Engineer (CRE)
  •    Contractor’s Engineering Manager (CEM)

Our extensive experience covers a wide range of rail works and includes milestone projects such as Cross Rail and Wales Region Asset Management.  Priding ourselves on being cost effective, flexible and responsive, we have an excellent track record of providing the services all our national and international clients require.

We work closely with our clients to fully understand the operational needs of complex industrial sites, ensuring our designs minimise disruption and shut down.

Our work within the UK, Europe and the Middle East has serviced clients within the petrochemical, pharmaceutical, agricultural and domestic food production industries.  We fully appreciate the harsh environments in which many industrial complexes are sited.  Therefore, our designs are always considered practical, commercial, safe and fit for purpose with minimal maintenance.

Infrastructure & Transportation

QuadConsult is able to offer a comprehensive Civil & Structural engineering design service for the provision of infrastructure works to bespoke projects across several sectors, such as leisure, agricultural and energy. Foul water treatment plants, access roads and drainage infrastructure provision, together with permanent car park design, are just some examples of services we are able to provide.

Flood Consequences Assessment & SuDS

We undertake Flood Consequences Assessments to meet the requirements of TAN15 ‘Development & Flood Risk’ in Wales, and Policy Planning Guidance (PPG) ‘Flood Risk & Coastal Change’ under the National Planning Policy Framework (NPPF) in England, usually in support of a planning application.

We are fully equipped to give advice on all aspects and impacts of SuDS legislation or the SAB process.



QuadConsult has many repeat clients in the retail sector.  We have a good relationship with household names such as Lidl, Costa Coffee, Iceland, Starbucks, Travers Perkins and M&P Motors, and have designed building conversions for outlets such as Tesco, Rola Wala, Harry Ramsden’s, The Alchemist, Slim Chicken, MOD Pizza, Frankie & Benny’s and 5 Guys. We have many commissions for building conversions from The Restaurant Group, and have designed whole retail parks. 

Sound sustainable design is second nature to us, allowing us to achieve accreditations such as BREEAM.
