RB Rail AS started the second stage of design and design supervision services procurement for the 56-km Upeslejas–Riga–Misa section in Latvia. The tender proposal submission deadline is 22 January 2019 and the contract duration will be 24 months.
The selected contractor will develop a master design, value engineering studies, spatial planning solutions and detailed technical design. In addition, the contract includes provision of the design author’s supervision during the construction phase of the line.
The Upeslejas–Riga–Misa section consists of three subsections, Upeslejas–Riga Central Station, Torņakalns–Imanta and Riga Airport–Misa River and is one of the most complex sections since it crosses densely populated urban areas and includes the only Rail Baltica tunnel on the whole Rail Baltica route.
According to the preliminary plans, 12 road viaducts, 16 rail viaducts, 13 segregated pedestrian crossings, 5 bridges, the second part of the railway overpass in Riga Airport as well as a cut and cover tunnel need to be designed for this Rail Baltica section.
The design of the section is a continuation of the earlier signed detailed technical design of Riga International Airport RB passenger station civil structures and junction contract as well as the ongoing procurement for the detailed technical design and construction of the Riga Central Station junction, explained Kaspars Ozoliņš, the State Secretary of the Ministry of Transport of Latvia.
In the near future, Latvia plans to sign the first construction contract.
“Design of the Rail Baltica line through Riga is a technically challenging task and we are pleased to see strong and experienced competitors taking part in the tender. The selected designer will play the key role in defining technical solutions in cooperation with a wide range of stakeholders, while also providing solutions to address the expectations of the surrounding communities, such as visual integration of the railway in the landscape as well as tackling noise pollution,” Ignas Degutis, RB Rail AS acting CEO said.
