Peru to begin design of Lima Metro Line 3 2 July 2014
Peter Kenyon, TunnelTalk
Two months after awarding US$5.6 billion construction of Lima Metro Line 2 to a consortium led by ACS subsidiary Dragados, Peruvian investment and procurement agency ProInversion calls expressions of interest for feasibility and initial design of Line 3. It is expected that final award of the consultancy contract will be later this month (July 2014), with tendering for civil contracts, likely to be on a concessionary basis, expected to begin in late 2015 or early 2016.
The broadly north-south alignment of Line 3 is currently designed to link the Santiago de Surco and Comos areas of the city, and features interchanges with Lines 1 (completed), 2 (under construction) and 4 of what is eventually intended to be a six line, 168km long metro system.

Initial design of Line 3 envisages an alignment that spans seven districts - Surco, Miraflores, San Isidro, Lima Cercado (Downtown Lima), Rimac, Los Olivos, and Comas, but this may change depending on the feasibility studies.
“We are initiating the call of the bid for contracting the consultancy that will perform the pre-investment studies of Line 3,” confirmed Javier Illescas, Executive Director of ProInvesion. “This task will take six months, after which we will prepare the procedures for an open call for the project. In parallel, we will prepare the first version of the contract.
“We expect to be in a position to let the contract, including construction, at the end of 2015 or the beginning of 2016. This timescale is based on the experience of preparing Line 2 for tender, though the actual timing will depend on the studies that will need to be performed and how the market responds.”
To that end a Peruvian trade delegation recently visited London as part of a world tour intended to encourage infrastructure investment in Peru. Illescas said: “Our visit to the UK was a very good opportunity to meet key representatives of the rail industry and promote the large investment being made by Peru in our local transport system.

“British companies have a deep knowledge of the industry and have a historical link to the Peruvian rail network dating back 100 years. We have hopes of attracting their skills once again and having them join us in what will be the biggest transformation and improvement of transportation in Peru.”
Earlier this year (March 2014) Peru awarded construction of the 27km all-underground Line 2 of Lima Metro to a Dragados-led consortium comprising Cosapi SA, Impregilo, Iridium Infrastructure Concessions SA, Vialia Management Company Infrastructure, Concessions SL, Ansaldo Breda SpA and Ansaldo STS SpA. The contract is a 35-year concession to design, finance, build, operate, maintain and transfer 27km of all-underground Line 2, as well as an 8km spur section to the airport (which will form part of Line 4). Construction of a total of 35 stations is also included in the construction contract.
Originally three bids were submitted, but Astaldi pulled out at the technical evaluation stage, and an Odebrecht-led consortium pulled out at the last minute after failing to reach agreement with ProInversion over financial details. This left just a single bid on the table, but the government decided to award the contract anyway, despite calls from the Peruvian national engineering federation to redesign the alignment and save costs by switching some sections to run at grade.
According to technical consultant Geodata, which worked closely with ProInversion on feasibility studies, preliminary designs, alignments, and geotechnical studies for Line 2, the tunnels will be designed as single bore/bi-directional. Excavation will be completed in two stages, each requiring four EPBMs for a total of eight machines, with a minimum TBM diameter of 9.2m. Project delivery time is 5 years.
