PRAGUE METRO LINE D | BTS
The Line D project timeline has had a long gestation
from initial concepts in 1983 through environmental and economic studies in the 1990s–2000s, zoning and building permits in the 2010s, and protracted permitting and procurement. Section 1a entered construction in 2022 after building permit award; Section 1b’s tender has remained under challenge since late 2022, with bidder objections, anti corruption reviews, and re awards extending the process. Mott MacDonald is responsible for the Detailed Design
of Section 1b. Below:
3. NOVÉ DVORY STATION Due to the phasing of the project, Nové Dvory station will operate as a terminus for several years. The mined single cavern station sits within a cluster of structures: a construction access tunnel; a crossover; turnout tunnels provided for a future western branch; and, a parking track tunnel linked to another ventilation shaft. The station platform will be 100m long and connect to the surface by a lift and two steep escalator tunnels, inclined to rise to the surface at about 60°. The site geology is dominated by clay-silty shales,
and silty shales ranging from weathered to fresh. The longitudinal geological section indicates the presence of two formations separated by a fault towards the northern end of the station. Detailed ground conditions remain uncertain and therefore the fault area has been represented by a 3m-wide vertical band, which will be a key focus for observational control. The station is to be fully waterproofed with the
groundwater anticipated to stand at about 19m above the station crown.
4. EXCAVATION AND PRIMARY LINING A key project milestone is to complete primary linings at Nové Dvory within two years to be able to accept TBMs driving in from the south. This has led to the multi-access approach of using shafts and escalators to start as many headings as feasible, in parallel. Five sites are anticipated to be excavated at the same time. Typical cross section of the station is 22.9m-wide and 16.1m-high, rising to a height of 17.9m at the junction
