How the Infrastructure Client Group is gaining scale, scope and strategic clout

The Infrastructure Client Group (ICG) has published its second annual report, passing another milestone on its quest to transform how UK infrastructure is delivered.

The group unites many of the nation’s largest infrastructure clients in sharing best practice across the sector and speaking with one voice to influence policy.

With new members in 2025 including Gatwick airport, the Sizewell C construction project, United Utilities and Great British Energy – Nuclear, it’s becoming ever more influential.

Key ICG activities in 2025

This year’s report highlights the work of the task groups the ICG has established in five strategic areas:

Climate Task Group, chaired by Rachel Skinner, executive director at WSP in the UK

Its remit broadened this year to cover nature-based solutions and climate resilience as well as carbon management.

It has not only been developing its Concrete Decarbonisation Accelerator programme, it has also started a new one called the Nature Accelerator.

Data and Digital Task Group, chaired by Ashleigh Monagle, strategic infrastructure adviser at Allora Infrastructure

Its Digital Integration Accelerator programme is helping to bridge the gap between design, construction and project management.

Meanwhile, its Adopters Group is promoting technical knowledge-sharing across the sector.

People Task Group, chaired by Sahil Chaini, regional market director at Transcend

Newly formed in 2025, it addresses critical factors in sustaining the infrastructure sector’s growth.

These include workforce planning, diversity, wellbeing and public engagement.

Productivity Task Group, chaired by Ed McCann, senior director at Expedition Engineering

This is working on several resources. They include the forthcoming PAS 4010 standard, a productivity maturity model and a route map to help infrastructure teams deliver better assets more efficiently.

Project 13, chaired by Dale Evans, partner at Allora Infrastructure

This task group is developing guidance and leadership programmes to support the sector’s uptake of the Project 13 approach – a more integrated, collaborative way to deliver infrastructure.

What’s next for the group

Reflecting the scale of improvements still needed across the infrastructure sector, the ICG is planning further ambitious and far-reaching work. This will include:

• Advancing the discovery phase of the Nature Accelerator Programme. This will build a UK-wide strategic nature network helping large landowners to restore natural capital across their estate.
• Expanding on the Concrete Decarbonisation Accelerator’s commitments to using low-carbon concrete and engaging the supply chain.
• Helping to develop PAS 3090, the first British standard for climate adaptation pathways, due for publication in 2026.
• Finalising the forthcoming PAS 4010 standard for infrastructure productivity and promoting it throughout the sector.
• Completing the productivity maturity model with the aid of pilot work by National Highways.
• Delivering a digital integration blueprint covering the entire infrastructure lifecycle.
• Exploring the evolving role of chief data officer in infrastructure organisations.
• Identifying the main factors helping and hindering the sector’s adoption of digital tech.
• Mapping HR initiatives in the sector and identifying areas for improvement, especially in recruitment, retention and employee wellbeing.
• Updating Project 13 resources to reflect lessons learnt by adopters of the approach and support further uptake.
• Launching a Project 13 leadership programme.
