NEC4 Focus.

Turning words into action

Clause 10 of the NEC4 contract sets the standard: act as stated in the contract, and in a spirit of mutual trust and cooperation.

These principles are simple to state but harder to live in the tensions of a live project.

The Clause 10 Collective exists to change that.

WHY IT
MATTERS.

The construction and engineering industries have long been held back by adversarial behaviours and short-term thinking. NEC®’s Clause 10 offers a different path — one grounded in integrity, cooperation, and shared values, to achieve better outcomes for clients, contractors, and regional supply chain communities.

The Clause 10 Collective provides a platform to share insights, tools, innovations, and behaviours that make collaboration a lived reality — not just a contractual aspiration. By working together, we can create an established norm for NEC4 project delivery: one where mutual trust and cooperation deliver measurable success and meaningful benefits.

OUR
PARTNERS.

Created by Solomons Europe in partnership with The Halcyon Club, the Clause 10 Collective brings together industry thought leaders who share a commitment to embedding trust, cooperation, and collaboration at the heart of project delivery — ensuring productive conflict and commitment to project goals deliver meaningful, collective project results. Over time, the movement will continue to grow through partnerships with other organisations and voices across the industry, reflecting the collective and enabling spirit Clause 10 demands.

This is a collaborative movement. Solomons Europe and The Halcyon Club are proud to lead it, but the Clause 10 Collective is built on the strength of its partners. Industry thought leaders, training providers, and professional bodies, and those we hope will continue to join us as we grow.
