Quality and Sustainability in our Products and Services

Quality in our products and services

Our reputation and ability to attract and retain clients and grow our business in line with our strategic objectives relies on delivering innovative, client- focused, future-proof solutions through our services and products. We ensure quality is maintained by following a consistent approach and adhering to international standards and recognised practices in quality management. They are incorporated into the way we work through WorkWise, our new integrated management system.

WorkWise streamlines and harmonises our working practices so we can be efficient and effective, ensuring consistency, reliability, coordination and synergy across disciplines and departments.

WorkWise brings together our various management system standards into one cohesive framework. It is based on and certified against international standards in the following areas:

  • Quality - Quality management (ISO 9001).

  • Health and safety - Occupational health & safety management (ISO 45001).

  • Environment - Environmental management (ISO 14001).

  • Integrity - Compliance management (ISO 37301), Anti-bribery management (ISO 37001).

  • Information security and data privacy – Information security management (ISO 27001).

  • Information management - Information management using building information modelling (ISO 19650) (as applicable to certain project scopes).

We are continually analysing and fine-tuning our working practices and processes to improve project quality and service delivery for our clients and to support our business objectives. One of the inputs for improvement is feedback from clients via our client satisfaction survey. In 2024, the average overall satisfaction score was 8.4 out of 10, maintaining a consistent level of overall satisfaction over successive years.

In 2024, our Corporate Quality, Health, Safety and Environment (QHSE) department coordinated internal QHSE audits in all our business lines and in 45 of our offices. These were conducted by our global network of independent internal auditors. External QHSE audits were conducted by DNV in the Netherlands, Poland, Singapore, the United Arab Emirates and the United Kingdom. As a result of these audits, our ISO 9001:2015 (Quality), ISO 14001:2015 (Environment) and ISO 45001:2018 (Occupational Health and Safety) certificates were continued to September 2025. External integrity & compliance audits took place in Australia, the Netherlands and India by EuroCompliance. These resulted in our ISO 37001:2016 (Anti-bribery) and ISO 37301:2021 (Compliance) certificates being continued to November 2026.

To support our growing strategic goals for QHSE within our company, we appointed two Global Leads in 2024: one for health and safety and one for quality and environment. Our Quality and Environment Lead will be taking forward our ambitions on quality management by further developing a standardised way of working and implementing our Business Process Management principles.

We renewed our certification against the requirements of Information Management using Building Information Modelling (BIM) in accordance with ISO 19650:2018 in 2024. Successful external audits were conducted in Australia, the Netherlands, the United Kingdom and Vietnam. ISO 19650 is the international standard for managing digital information throughout the life cycle of built assets and construction projects of all sizes and levels of complexity. The certification shows we are committed to using a standard approach to define, create, validate, and share project information.

Sustainability in our products and services

As a company, the positive impact we achieve through our work for clients is far more significant than reductions we make on our direct footprint. To maximise this impact, it is important that all our people and systems reflect and reinforce our purpose. We always challenge ourselves, our teams and our clients for more sustainable solutions. Until early 2023, we demonstrated project impact through individual project examples.

From April 2023, we started measuring the impact of our projects on people and planet on five themes: climate change, biodiversity, resources, social value and safety. In 2024, we more than doubled the number of projects assessed against these five themes to cover projects making up more than 60% of our revenue. Read more about this in Sustainability Performance under Purpose Chart.

Clients are asked for feedback when projects are completed. Most of our clients rate us Good or Very Good on delivering on our purpose of Enhancing Society Together. In 2024, this resulted in an average Enhancing Society Together score of 7.7 out of 10, which is a slight increase compared to previous years.
