Costain has been appointed to Pagabo’s National Framework for Civil Engineering, Infrastructure and Enabling Works 2026, securing a position as a Lot 1 Collaborative Partner for England and Wales.
The appointment marks the beginning of a new relationship between the infrastructure specialist and procurement organisation Pagabo, creating an additional route for public and private sector clients to access Costain’s consultancy, engineering and project delivery expertise.
The framework, which has an estimated value of £4.29bn, will run for four years until 2030 and is designed to connect public sector bodies and private organisations with contractors capable of delivering major civil engineering, infrastructure and enabling works projects.
Costain is one of only three suppliers selected for the Lot 1 Collaborative Partners category, covering England and Wales. Through the framework, the company will support customers through the entire project lifecycle, from early-stage development and strategic planning through to design, construction and delivery.
The appointment spans a broad range of infrastructure sectors, including rail, road, aviation, water, energy, defence and civil nuclear. Costain said its integrated advisory, engineering and delivery approach will help customers improve project outcomes, manage risk and enhance constructability from the earliest stages of development.
With more than 160 years of experience delivering complex infrastructure projects, Costain believes its cross-sector expertise will help clients develop and deliver schemes more efficiently while generating long-term economic, social and environmental value.
Alex Vaughan, chief executive of Costain, described the appointment as a significant milestone for the business. “This is another landmark moment for Costain as we begin our relationship with Pagabo and significantly increase the ways public sector organisations can access our expertise,” he said. “Working collaboratively with Pagabo, the public sector and our supply chain partners, we will deliver predictable, best-in-class engineering and infrastructure projects that will improve people’s lives and create a more prosperous, resilient and decarbonised future for all.”
Pagabo said the new framework was created to provide public sector organisations with access to specialist expertise and delivery capability across a wide range of infrastructure disciplines.
David Llewellyn, construction and infrastructure director at Pagabo, said the framework represents an important step in supporting the delivery of high-quality infrastructure projects across the UK. “The launch of the National Framework for Civil Engineering, Infrastructure and Enabling Works 2026 marks an important step in providing public sector organisations with access to a broad range of specialist expertise and delivery capability,” he said. “The range of suppliers appointed have been rewarded based on evidence of their ability to collaboratively deliver high-quality infrastructure, civil engineering and enabling works projects across the UK.
“Through the procurement support that Pagabo provides, and the ambition proven by the appointed suppliers, the infrastructure sector is in safe hands.”
The framework award strengthens Costain’s position in the UK infrastructure market and provides public sector organisations with streamlined access to the company’s capabilities as investment in transport, energy, water and other essential infrastructure continues across England and Wales.
