The holding operates also in Russia , Ukraine , Belarus , Kazakhstan , Uzbekistan , Germany , and Middle East . It employs more than 3,500 workers. Besides construction activity, Glavbolgarstroy invests in tourism and vacation real estates, and produces and trades construction materials. It plans to invest a total of EUR 30mn in the large winter resort Super Borovets and in another one in the north-western town of Berkovitsa . It is rumoured in the local press that the holding would participate in the second tender for modernisation of the first terminal at Sofia Airport . The road construction holding Trace Group operated a 10% capital hike in a public offering last week, which attracted bids for a total of BGN 32bn or nearly 60% of the projected full-year GDP. Yesterday, another construction company, the Greek-owned Venus, announced plans to offer shares on the local stock exchange.
