Euan Caskie, a director of the company, said: “This is a deeply tragic incident, and our thoughts are with his partner, his six children, and his wider family at this incredibly difficult time.
“He was a respected and valued member of our team.”
An online crowdfunder to help with funeral costs for the family has been set up by Ardeer Thistle FC Youth Academy, the club one of his children plays for.
The club described him as a loving husband and fantastic dad.
They stated: “Derek worked hard for his family and any donations would be greatly appreciated to help support his family at this time.”
A large-scale emergency response, including police officers, fire crews and specialist ambulance teams, had attended the scene at about 09:15 on Friday, while a cordon was put in place around the part-demolished building and an excavator machine, sitting on top of a pile of rubble.
A Police Scotland spokesperson previously said: “An investigation into the circumstances remains ongoing and the Health and Safety Executive have been informed.
“A report will be submitted to the procurator fiscal in due course.”
