Under the new agreement, McAvoy has secured the opportunity to provide bespoke modular buildings and interim hire facilities with a particular focus on education and healthcare.
The framework also covers public buildings such as facilities for the emergency services, MOD, community centres, offices, care homes, student accommodation and other residential schemes. It will operate for the next four years and covers England, Scotland, Wales and Northern Ireland.
This is the fourth consecutive CCS framework that McAvoy has been awarded and it follows a rigorous independent assessment process.
The group was successful in winning a number of major free school projects under the previous CCS modular building contract which were built offsite, including the £20 million Lynch Hill Enterprise Academy in Slough and Goresbrook School in London - an £18m all-through school taking children from nursery to sixth form.
Eugene Lynch, chief executive of The McAvoy Group, said: "Long-term frameworks are very important to our business and are a major source of new contracts, helping us to continue to grow sustainably. We look forward to working with CCS over the next four years.
