Prague public transport authority Dopravní podnik hlavního města Prahy (DPP) is seeking a geotechnical monitoring partner for upgrade of Metro Line C and surrounding buildings.
According to the tender documents published in the Official Journal of the European Union, the 49 month contract is worth CZK115M (£4.1M) and will cover the construction period and two years after completion.
The tender was originally published in December with a deadline of 10 January but that has now been pushed back to 18 February to expand the net for potential bidders.
DPP has said that the work is related to geotechnical monitoring of the existing buildings including the part of the Metro Line C undergoing redevelopment. The successful bidder will undertake investigations of the rock mass to understand if it has been affected by the metro work or ongoing natural processes, as well as predict future movement and potential remediation measures.
