Its project record includes award-winning work recognised in the Latvian Construction Annual Award (Latvijas būvniecības gada balva) and in Baltic sustainability in architecture, construction and design awards.

It is not known to be listed on a stock exchange and is treated here as a private company. Its brand identity is built on engineering expertise, quality assurance and sustainability rather than on consumer products, and its client base is composed mainly of developers, contractors, municipalities and public infrastructure owners.
