Bulgaria

For over 20 years we have contributed to Bulgaria's infrastructure development in areas including renewable power generation, motorways and border crossings, and water and waste disposal.

43 miles
(70 kilometers) of motorway: construction supervision
410 miles
(660 kilometers) of primary roads: managing upgrade
55 miles
(88 kilometers) of rail line: design

Water

We’re working to improve water quality while reducing the cost of operating and maintaining water and sewerage infrastructure, with projects in Sofia, Haskovo, Plodiv, Burgas, and St. Zagora. We’re upgrading infrastructure and introducing improved management technologies and techniques, including procurement and contract advice, project management, hydraulic modeling, and leakage detection systems.

The Bulgarian government appointed us as technical advisor to develop a new wastewater treatment plant and related sewerage infrastructure in Haskovo, as part of a European Investment Bank-funded initiative. The town’s untreated wastewater had been discharged into the Haskovska River. The treatment plant improves the water quality of the Aegean Sea, contributes towards a better environment, and reduces the risk to public health. The effluent standard complies with EC Directive 91/271/ EEC and the treatment and disposal of sludge complies with relevant EC directives.

Transport

We've been helping to project-manage the country's ongoing program of road and bridge rehabilitation. We supervised construction of 43 miles (70 kilometers) of motorway between the Bulgarian capital Sofia and the Black Sea port of Burgas. We are currently managing the country’s Transit Roads Project IV, involving upgrading, rehabilitation and reconstruction of 410 miles (660 kilometers) of primary roads. This mammoth program of work is funded by the Government of Bulgaria and the European Investment Bank. We're also developing an integrated transport plan to improve sustainability and safety in Sofia.

European Union funding aimed at improving connectivity and reducing the volume of freight carried by road is fueling significant work in the heavy rail sector. We led preliminary design, environmental impact, and economic viability studies for a 55-mile (88-kilometer) rail line between Radomir and Gueshevo.

Environment

We have been busy on a range of essential environmental projects. We provided technical assistance including training to the Ministry of Environment and Water for a €60 million EU-funded project to implement six regional waste disposal sites in Montana, Pernik, Rousse, Sevlievo, Silistra, and Sozopol, plus a transfer station in Primorsko on the Black Sea.

Power

We have worked a number of significant wind power projects in Bulgaria, helping to increase the country’s own electricity generation.

For the 60-megawatt Suvorovo Wind Farm development in Varna Province, we provided lender’s technical advisory services to the European Bank for Reconstruction and Development (EBRD) and the Black Sea Trade and Development Bank (BSTDB).

The project consists of 30 Gamesa G90 2-megawatt wind turbines and a high-voltage substation and generates around 130 gigawatts of electricity per year. We are now providing operations monitoring of the wind farm, which involves reviewing of the technical and financial performance of the project.

We provided lenders’ technical advisory services during construction of the 35-megawatt Kaliakra wind farm on the Black Sea coast of Bulgaria. Since commercial operation began in 2008, we continue to undertake annual operation monitoring to report on technical issues affecting the wind farm’s performance.

The neighboring 156-megawatt St. Nikola wind farm began operation in 2010. We have undertaken an ongoing role as lender’s technical advisor to the European Bank for Reconstruction and Development (EBRD). We monitored the construction phase and continue to provide operation monitoring.
