Accreditations and quality

One of our main objectives within GMG is to raise standards in all areas in which we work – to strive for perfection within our industry.

GMG has focused on three particular areas of quality management, with stringent external auditing from award-winning international certification bodies.

The first is BS EN ISO 9001: 2008 International Quality Management System.

GMG also recognises the importance of protecting our planet and is committed to incorporating ecological considerations into their business activities and striving to maintain the highest standard of environmental performance.

We believe that proactively managing environmental issues is in the best interest of our employees, customers and the communities we serve, so we currently also operate to the requirements of Environmental Management legal compliance standard BS EN ISO 14001: 2004.

Finally, we have achieved ISO 45001: 2018 (Occupational Health and Safety) certification, which demonstrates that we are committed to reducing accidents, complying with the law and improving our overall health and safety performance.

This increases employee, customer and stakeholder confidence in our management systems, enhances our brand and gives us a competitive advantage.

The ISO family of Quality Management Standards was globally designed and introduced to assist organisations and ensure that they meet the needs and requirements of clients, while meeting both statutory and regulatory requirements of a particular programme.

We’re proud to be recognised by several industry-leading accreditations, ensuring that we deliver the best service to all our clients. Our certifications include:

ISO 9001: 2008 (International Quality Management)

ISO 9001 is based upon seven core Quality Management Principles (QMP):

  • QMP1 – Customer focus
  • QMP2 – Leadership
  • QMP3 – Engagement of people
  • QMP4 – Process approach
  • QMP5 – Improvement
  • QMP6 – Evidence-based decision-making
  • QMP7 – Relationship management

ISO 14001: 2004 (Environmental Management)

GMG adopted the ISO 14001 standard because we take our environmental responsibilities extremely seriously.

Construction’s biggest environmental problem is wastage of material. By continually finding new ways to recycle material and working closely with the Technology and Innovation Centre at the University of Strathclyde, GMG is assisting to not only reduce its own carbon footprint but also on finding new ways to improve the industry’s key performance indicators on waste.

ISO 45001: 2018 (Occupational Health & Safety)

ISO 45001 is an internationally applied British Standard for Health and Safety management. Its primary objective is to put in place and implement best practice for a company to utilise in all aspects of Health & Safety.

The construction industry has improved significantly over the last three decades in this regard but, with a bespoke developed system, GMG aim to continually strive to ensure all our staff, and those around us, are safe and healthy in their workplace.
