Kupittaan kärki Partnership Project, Turku
The development stage of Jokeri Light Rail involved the design and implementation of a light railway and a depot. The project is based on a so-called alliance model and is carried out together with the other parties in the alliance.
Jokeri Light Rail is being constructed between Itäkeskus in Helsinki and Keilaniemi in Espoo. Jokeri Light Rail will increase the reliability of public transport in the East-West direction in the Helsinki metropolitan area. It will also open up opportunities for new residential construction along the fast light railway. The length of the light railway line will be about 25 kilometres, of which about 16 km in Helsinki and 9 km in Espoo. The line will have 34 pairs of stops. The new line is scheduled to start operations in autumn 2023. The project was originally scheduled for completion in summer 2024, but the timetable was compressed by almost a year.
The client organisation (the cities of Helsinki and Espoo), the designer organisation and the contractor form a joint organisation called an alliance. The contractors were selected in a separate tendering process. The winning coalition consisted of YIT and NRC Group Finland. We serve as the project supervisor in this project for the construction. A consortium consisting of Ramboll Finland Oy, Sitowise Oy and Sweco serves as a design consultant for the project.
As a major service provider, we can handle large projects. We have good resources and a wealth of expertise and know-how. The project includes the design and implementation of a light railway and depot. In the alliance model, cooperation between the client and the designers is continuous and immediate. A common workspace, the Big Room, ensures fast information flow and strengthens cooperation.
The principles and advantages of the alliance model are well understood in Jokeri Light Rail. Plans drawn up during the development phase have been made in collaboration with designers and builders. In this way, the plans turn out viable and the transition to the construction phase is smoother than in the traditional model, where design and construction are successive, separate steps. The collaboration has also enabled us to get accurate cost information.
“Urbanisation plays a significant part in our current strategy and Jokeri Light Rail is an excellent and sustainable solution for the metropolitan area’s internal traffic. YIT is highly experienced in alliance contracting and our organisation has a very broad and diverse range of expertise. We can simultaneously carry out multiple large alliance projects without problems. Even a huge and highly challenging infrastructure project like this can be successfully and cost-efficiently managed in cooperation with all the alliance partners,” says Antti Korhonen, Vice President, YIT.
In the development phase of the project (12/2017–5/2019), we prepared an implementation plan that covered the schedule and costs of the construction project. An integrated project organisation was set up during the development phase and a target cost for the alliance was calculated, to which all the parties of the alliance committed themselves. The implementation phase and the actual construction work started in June 2019. Now, after the construction work, several tests have been carried out and test traffic has begun.
Project content on our part:
Jokeri Light Rail will enable the future growth of commuter numbers and help to avoid congestion. Jokeri Light Rail will replace the bus line 550, which carries nearly 40,000 passengers a day. It is estimated that by 2025 there will be 90,000 passengers on each weekday. A passenger rail car can accommodate nearly three times more passengers than a bus. In addition, the new high-speed light railway will advance the construction of new homes and services along the line. It will also reduce traffic emissions significantly.
