Prequalifers are being called for the construction of a new US$3 billion light rail metro system for the Saudi Arabian capital of Riyadh.

Arriyadh Development Authority (ADA), which is overseeing the Riyadh Public Transport Project, issued a notice calling for international consortia with metro tunnelling experience to notify their interest.
The project will be let on a design-build basis, with local media souces claiming that up to 80% of the 40km eventual alignment will be tunnelled. In a TV interview earlier this month (May 2012) Saudi Arabia's Minister of Transport, Dr Jabara bin Eid Al Sraisribuilt, said the project would be constructed in two phases: a 27km Phase 1 north-south alignment and a 13km Phase 2 east-west alignment (Fig 1).
Phase 1 is scheduled for completion by 2014.
Preliminary designs, a feasibility study, traffic study, environmental impact assessment, cost estimate and performance design specifications have already been drawn up by design consultant dar-al-hanasah (Shair and Partners), a process that has been ongoing since 2004.
The company said the project aims to alleviate the capital's congestion and is comprised of two LRT lines along Olaya Street (north-south) and Prince Abdullah Road (east-west). Components include a mixed alignment; at-grade, elevated and underground; with 40 stations, transportation centre, depot, and park-and-ride facilities.
The company's services have included GIS-based screening modelling of air-borne noise and ground-borne vibration, and providing input to the multi-criteria analytic framework for evaluating the option alignments.

The new metro is seen as vital for solving the Saudi capital’s chronic traffic problems. According to studies carried out by ADA nearly 85% of the population of Riyadh uses private cars as their primary mode of transport, with a mere 2% taking advantage of a very limited public transport system.
The deadline for submission for applications for prequalification is June 20.
In November 2010 the first phase of Saudi Arabia's first metro system, an 18.1km elevated alignment in Mecca, was completed by the China Railways Construction Corporation. A project study was completed last year (2011) for a 108km three-line metro system in Jeddah, Saudi Arabia’s second city, though the long-awaited tender process has not yet begun.
In neighbouring Qatar, Qatar Railways is currently evaluating bids submitted by 18 consortia for five tunnelling and station construction packages for the Doha metro. Phase 1 is expected to comprise 49km of TBM-excavated twin running tunnels as part of an eventual four-phase US$35 billion project that will see 358km of new track laid across a mixture of at-grade, elevated and underground alignments.
