Bulgarian construction company GP Group has retracted its offer in a tender for a contract for reconstruction of a tramway section in Sofia, which is part of the EU-financed second phase of the Sofia integrated public transport project, public radio broadcaster BNR reported on Monday. The public procurement procedure is not completed yet as the contract has not been signed, and the municipality will pick the next-ranked offer, Sofia mayor Yordanka Fandakova was quoted as saying by BNR. In August, Sofia municipality ranked first a 45.7 million levs ($27.1 million/23.4 million euro) offer by Infra Group tie-up, comprising GP Group and local RVP Ilienci, in the tramway upgrade tender. The second-ranked offer was filed by a tie-up comprising Spain's Marco Obra Publica and Bulgaria's Integrated Construction Systems, and amounted to 47.5 million levs. In addition to the higher price, the offer was also ranked lower in terms of technical criteria.
