“We are delighted, therefore, to renew our relationships with Morrison, Morgan Sindall and Keir and to celebrate our new partnership with BAM Construct UK and Robertson Construction.

“Our newest partners bring to the table their rich experience in the education, leisure, and healthcare sectors. Our shared values mean that each is aligned with our needs and reflect our ambition to deliver sustainable, high-quality infrastructure for our communities. We look forward to working with them.”
