Nearly 250 people have been made redundant in the Highlands, Western Isles and Central Belt after four construction firms went into administration.
Zolfo Cooper have been appointed administrators of the companies, which traded as UBC Group, Wyvis Building Services, Wyvis Roofing and Mardon Project Services.
The administrators say they hope to find a buyer for Wyvis Roofing, but trading at the other three firms has ceased with immediate effect, leaving 238 staff redundant.
Across the companies' offices, 98 people will lose their jobs in Inverness, 90 in the Western Isles, 45 in Bathgate, West Lothian and five in Stepps.
Administrators hope to save 30 jobs at Wyvis Roofing in Inverness by selling the company.
Elizabeth Mackay, joint administrator and lead partner for Zolfo Cooper in Scotland, said: "It was with great regret that we have had to take today's extremely difficult decision.
"We are fully aware of the impact that these redundancies have on the communities in which UBC Group operated for many years and my team and I will be working with all relevant agencies and third parties to seek to minimise the impact as much as possible.
"Unfortunately, the Group's overall financial position had become untenable and a lack of outside interest in acquiring the business as a going concern meant that today's decision was the only remaining course of action available.
Zolfo Cooper said that the joint administrators will be working closely with the Scottish Government and other agencies to help former employees in their search for new jobs.
