The latest lay-offs bring the number of job losses to 1,066 across the collapsed Rok empire.
Inverness based subsidiaries Rok Civil Engineering and Tulloch Transport were placed in administration on Friday, and both have been closed by PwC with all jobs lost.
Tulloch Civil Engineering was rebranded Rok Civil Engineering following the firm’s acquisition in 2006.
The workforce was officially made redundant last night.
One employee, Owen Armitt, 47, told the Aberdeen Press and Journal he had not been paid since October 11.
The father-of-two said: “We are feeling pretty down. I have worked for the business for 14 years as I worked for Tulloch Civil Engineering before it became Rok.
“We thought our jobs were safe. We have just been working on a job for Scottish Water in Aviemore. I don’t know who is going to do that job now.”
Site manager Chris Wright, 58, said: “The writing was on the wall. We knew what to expect. It seems as though we are being hit by what has happened to the British part of the business.”
Alan Brown, joint administrator, said: “Due to a number of economic reasons and as a result of little or no interest in these businesses from prospective purchasers, we have regrettably had to take the decision to close these businesses and make the entire workforce redundant.
“The 87 employees impacted will have access to an employee relations helpline and during our discussions with them, have been assured that they will be paid for the period they have worked since our appointment as administrators.
“We are continuing to progress the expressions of interest we have received to date for the remainder of the contracts and business in Scotland and would expect to have further updates over the coming days.”
