It placed the blame on subcontractors going bust.
In a third quarter trading update, the board said: “In the UK, whilst the performance of our building and fit-out businesses is encouraging, this year's segmental result will be impacted by three loss-making energy process contracts within our infrastructure business.
“This is due in large part to subcontractor insolvencies and the consequential impacts on project timing and costs. Our involvement in the delivery of these contracts is substantially complete. Expectations for the full year are for a break-even performance in the UK Construction segment.”
However the equipment services division – RMD Kwikform – “has continued to deliver outstanding growth”, the construction business in the Middle East is strengthening and support services “continues to perform well”.
