BUILDING THE INFRASTRUCTURE OF TOMORROW

Trusted Partner to Tier 1 Contractors

We’ve built long-standing relationships with major contractors, delivering specialist packages that are critical to programme success. Our collaborative approach, transparency and technical excellence make us a partner of choice on major infrastructure schemes. Engineering certainty through early contractor involvement.

Through early contractor involvement (ECI), we optimise methodologies, reduce programme risk, improve cost certainty and support value engineering. Our input at pre-construction stage consistently leads to smoother, safer delivery on site.

We have a strong track record on complex, high-profile infrastructure schemes in the UK and internationally. Our teams deliver specialist works that are critical to the success of major rail, water, energy, aviation and marine projects. Expertise across every tunnelling method

From TBM and EPB tunnelling to pipe jacking, microtunnelling, HDD and shaft sinking, we apply the most effective techniques for each environment. Our multi-disciplinary expertise allows us to design and deliver the best technical solution for every project.
