The move signals a shift in emphasis away from transport infrastructure, with the contractor instead channelling resources into large-scale building projects where demand for its technical expertise is strongest.

Its special projects team will now sit within the commercial arm, while defence and nuclear work are folded into the industrial division. All sectors will report directly to chief executive Neil Martin.

The reorganisation will not impact projects already on site, with changes limited to management and reporting lines.

Some back-office roles will be rationalised, but operations will continue as normal.

The new SRM board shrinks from nine to six to speed up decisions and improve efficiency.

Former executive MDs Grant Findlay (buildings) and Steve Hudson (infrastructure) are stepping down from the board but will remain with the business.

Engineering and technical services director Andrew Hunter is leaving the business.

Neil Martin said: “Thanks to the ‘Evolving SRM’ strategy we launched in 2023, the business returned to profit in the last financial year and is on course to deliver further improvements in pre-tax profit in the current financial year.

“We have a strong cash position, and our order book has grown to stand in excess of £2.2bn.

“The strength of our sustainable engineering and technical capabilities has been a key factor for clients contracting with us on large-scale complex projects within our core sectors.

“As a result, we’re able to conclude our strategic reorganisation, introducing changes that will help the board get closer to our projects and clients, improving communication and connectivity and allowing for more agile decision making.”
