Bulgaria's competition authority said it will consider a complaint related to a 116.7 million levs ($67.6 million/59.7 million euro) tender of Sofia Municipality for maintenance and current repair of roads in the city. The complaint over a requirement for the candidates was filed by local company Interprom on October 23, the Commission for Protection of Competition said in a notice announcing the opening of proceedings on Thursday. More specifically, the city government requires each candidate to prove that it has access to an asphalt plant with output capacity of 100 tonnes per hour, tender documents published on the website of Sofia Municipality show. A company can bid using its own asphalt plant, and at the same time sign a contract with another candidate in the tender, under which the second company will use the same plant. However, such an arrangement will only be accepted if the asphalt plant can meet the needs of both companies at the same time, i.e. it can produce 200 tonnes per hour. The tender, launched in September, is divided into seven lots, each of them for a four-year contract for maintenance and current repair of part of the city's road infrastructure.
