Construction Only Award
Client: Trafikförvaltningen (the Transport Administration, Stockholm County Council)
Tram Line 7 is currently in regular service between Kungsträdgården in Stockholm city and Waldemarsudde in South Djurgården. The (Spårväg City) tram system is planned to be expanded and link Lidingö with Stockholm city via Stockholm Royal Seaport, the new sustainable urban development in Frihamn and Värtahamn. The first stage of this expansion, assessed in accordance with CEEQUAL, is the accessibility upgrade of Tram Line 7 and the tram stops in South Djurgården.
12,000 new homes and 35,000 new workplaces are under construction in Stockholm Royal Seaport, and Spårväg City will supply most of the public transport services. In addition, South Djurgården is the world’s seventh largest entertainment centre with more than 14 million visitors annually. Visitor statistics for South Djurgården indicate that this number will continue to rise; hence Tram Line 7 is an important connection for Stockholm’s economy.

Challenges faced and Achievements
The project has largely been conducted in collaboration between the two major stakeholders, namely the client, Trafikförvaltningen (the Transport Administration Stockholm County Council), and the contractor, Skanska. The project was procured as an explicit collaborative project, and the Transport Administration as client has collaborated with Skanska, the contractor, on the accessibility upgrade of Tram Line 7. Together they have been collaborating to find solutions that are environmentally and economically responsible, as well as taking into account health and safety. Project members have been committed to working towards common goals and to come up with innovative solutions. Environmental and sustainability issues have been prioritised in the project agenda through collaboration and the use of CEEQUAL. During the project regular collaboration meetings have been held between the project management groups of each organisation.

Clear structures and procedures for working with environment and sustainability:
A part of the Transport Administration’s work has involved breaking down the environmental plan and checklist for the programme as a whole into a project-specific requirements list, which can then be used as a tool during further collaboration with the contractor. Project-specific procedures have been developed for product selection, chemicals and work with CEEQUAL. Regular environmental meetings/workshops have been held together with environmental officers from the contractor and the designer as well as regular status meetings and sessions to follow up the environmental work during actual production. Clear procedures and structures have facilitated the effort to meet set environmental standards.
People and Communities
The project to improve accessibility on existing Tram Line 7 is in its entirety an element in a commitment to social sustainability which ensures that all passengers have access to and from both buses/trams and platforms. Part of this has involved building test platforms to assess the best design for the accessibility features. The test platforms were visited by the project staff and by the resource group in particular, which consisted of representatives from various disability organisations who provided their views on the necessary prerequisites to achieve satisfactory accessibility. The resource group was also invited to take a tram ride after the accessibility upgrade had been completed in order to evaluate the results. Part of the efforts to reach all passengers has involved a study of how children experience travelling by tram. This will form the basis for the future planning and design of tram facilities.

Another important element has been the ongoing dialogue with their stakeholders, both within the organisation at the Transport Administration itself and with the third parties and operators in the area where we are working. The project has distributed regular newsletters and organised meetings for local residents and businesses. The project has also worked closely with the transport operator to monitor how work on the upgrade is impacting passenger environments.
Within the project, the aim has been to achieve a high level of third party satisfaction. The target is to achieve 80% after the upgrade. A survey of perceived quality is carried out every month and from February 2015 local trains achieved 86% (compared to the other modes of transport: Metro 82%, rail 75%, bus 74%). For Tram Line 7, customer satisfaction stands at 93%, the highest level for any transport mode in the SL network. Regarding the production on Djurgården, no major complaints have been received, which the contractor has worked hard to ensure.

Temporary tramway points:
The use of temporary tramway points has for many decades been a “forgotten technology” in Stockholm, one which the project has now revived. It has allowed tram services to be maintained during production to the benefit of both passengers and the construction team, and the latter has been able to perform its work with a higher level of safety and security. Passengers have been able to continue travelling by tram, and replacement bus services have been avoided, which has reduced the environmental impact of the project (emissions) as well as its cost.

Ecology and Biodiversity
The tramway currently runs parallel to the tree-lined avenues on Strandvägen, and there are trees on Djurgården growing in very close proximity to tram installations. In conjunction with the upgrade of the existing line on Djurgården, the project has been in close dialogue with the Royal Djurgården Administration, which manages the land and trees in the area. The dialogue has been very positive, and consideration has been taken during the accessibility upgrade to avoid damaging trees both during operations and production. For example, measures were taken to protect a specific lime tree on the platform at the Nordiska museet stop. Vacuum excavation was performed and the tree’s root system was protected so that both the tree and passengers can co-exist on the platform.
Transportation, waste and water:
During construction, commitment was made to optimise transportation from both an environmental and a logistics perspective. The same prerequisites have applied for waste management and earth removal during the project. Workers on site came up with the fantastic idea of collecting rainwater for use during dust control instead of using drinking water.

To what extent did the use of CEEQUAL influence your project?
CEEQUAL as a tool has provided guidance in every phase of the project, providing traceability in all areas. Focus has shifted from constant checks to a desire and appreciation for continuous improvements.
CEEQUAL has had an influence across the whole project (client, designer and contractor). This has been shown through initiatives including:
• Construction of a rainwater collector to minimise water consumption during dust control after cutting.
• Bodystorming; a creative way of capturing the third party view of the site that involves a “test walking/travelling” along service, pedestrian and cycle lane diversions. Parts of the results have also been shared on Cykelbloggen (an online blog) to facilitate and provide clarity for cyclists.
• Small cobblestones found during construction have been recycled in a creative and aesthetic way.
• Accessibility features along Tram Line 7 were expanded to include a ramp down to the Djurgårdsslätten residential area from the Skansen stop. The additional work was carried out after discussions between third parties, the designer and the contractor, and will benefit a large number of people.
• Signs and road markings at Djurgården School that did not exist previously. During the construction period, it was made sure that the children could get off at Skansenslingan so they avoided having to cross the street to get to school.
• During the design phase, various types of lighting and aesthetic adjustments in the surrounding environment were proposed.
