The $5bn Qiddiya high-speed rail in Riyadh has received PPP prequalifications from interested firms as deadline approaches. The Saudi Arabia’s Royal Commission for Riyadh City in collaboration with Qiddiya Investment Company (QIC) received the statements. Furthermore, the National Center for Privatization & PPP was also involved. The statements were submitted by firms on 30 April for the public-private partnership (PPP) package of the project in Riyadh.
This follows the submission of prequalification statements for the engineering, procurement, construction and financing (EPCF) package on 16 April. Moreover, the prequalification notice was issued on 19 January and a project briefing session held on 23 February.
This was done at the Qiddiya Entertainment City (QIC). Once complete, the rail project is expected to connect King Salman International airport and the King Abdullah Financial District (KAFD)). The line will also operate at speeds of 250 kilometers an hour, reaching Qiddiya in 30 minutes. Other than rail projects, Riyadh is focused on a wholesome enhancement of its transport sector with roads also getting advancements. This includes Riyadh’s $1.6 billion road upgrades project that aims to improve roads in the region in time for the Expo 2030.
Outlook on the Qiddiya High-speed Rail in Riyadh
The Qiddiya high-speed rail in Riyadh is expected to be developed in two phases. The first phase will connect Qiddiya with KAFD and the King Khalid International airport. On the other hand, the second phase will start from a development known as the North Pole. It will then travel to the New Murabba development, King Salman Park, central Riyadh and Industrial City in the south of the city.
