ICGB, the project company developing the Gas Interconnector Greece-Bulgaria, said on Monday that it has opened a 145 million euro ($175.6 million) tender for the design, procurement and construction of the gas link. "The launch of this procurement ensures the actual commencement of the construction of the pipeline and we expect entering into commercial operation in 2020," Dr. Konstantinos Karayannakos, executive officer of ICGB on the Greek side, said in a statement. The selection of a contractor will be carried out in two phases - pre-selection, followed by review, evaluation and ranking of offers. Through a preliminary selection ICGB will assess and determine the candidates which have the required financial and technical capacity to implement the subject matter of the public procurement according to the set requirements, the company said.
