Sustainable urban centre Tripla was created in teamwork of multiple parties<\/h1>\n

A new city district has risen between Eastern and Western Pasila in the past few years. Central Pasila represents modern, dense and sustainable urban planning. Tripla, the nerve centre of the area, consists of Mall of Tripla and the Pasila railway station.<\/p>\n

The enormous\u00a0Tripla\u00a0construction project has involved multiple operators. Sweco\u00a0was in\u00a0charge of\u00a0the principal and architectural design and structural engineering for the eastern third of\u00a0Tripla, the station block, as well as any solutions in terms of city landscape for the entire project with\u00a0Arkkitehdit\u00a0Soini & Horto. Furthermore, Sweco\u00a0was in charge of\u00a0the structural design for the station block. The project has required seamless cooperation from Sweco\u2019s architects and structural designers.<\/p>\n

All roads lead to Pasila<\/h4>\n

The design for\u00a0Tripla\u00a0was initiated in 2011, when YIT, Office for Metropolitan Architecture and\u00a0Arkkitehdit\u00a0Soini & Horto won the architectural competition for the implementation of the new centre of Pasila. Construction began in spring 2016, and\u00a0Tripla\u00a0was opened in October 2019.<\/p>\n

The project is based on the City of Helsinki\u2019s vision of expanding the city centre to the north and making Pasila the most accessible place in Finland. Its location at the intersection of the\u00a0Keh\u00e4rata\u00a0railway with a connection to the airport, the western additional railway and, in the future, the City Rail Loop make\u00a0Tripla\u00a0a unique transport hub. In 2025, 130,000 passengers and 900 trains will travel through the station daily.<\/p>\n

\u201cPasila is growing strongly, and a number of new apartments are being built north of\u00a0Tripla\u00a0as we speak. Its location and vicinity to the Helsinki city centre make Pasila an ideal location for creating a denser city,\u201d summarises Sweco\u2019s main designer, architect\u00a0Pekka\u00a0Ojalammi<\/strong>.<\/p>\n

According to\u00a0Ojalammi, the sustainable design of the area started from traffic solutions and public transport.\u00a0Tripla\u00a0can be reached from many directions on foot, by bicycle and by train, bus and tram. A tunnel for a potential metro line has also been constructed.<\/p>\n

\u201cThe design solutions ensure that Pasila\u2019s public transport will always be functional,\u201d\u00a0Ojalammi\u00a0states.<\/p><\/blockquote>\n

In terms of urban structure,\u00a0Ojalammi\u00a0feels that connecting the eastern and western parts of Pasila was one of the biggest challenges in the project. In its day, Eastern Pasila was built by separating pedestrian traffic from vehicle traffic\u00a0onto a higher deck level. However, the route did not reach Western Pasila.\u00a0Tripla\u00a0now seamlessly connects Pasila\u2019s eastern and western parts. \u201cPeople can walk through\u00a0Tripla\u00a0on many levels,\u201d\u00a0Ojalammi\u00a0explains.<\/p>\n

According to\u00a0Ojalammi, one of the key challenges in\u00a0Tripla\u2019s\u00a0architectural design was to observe the human scale and create an enormous building that does not feel overwhelming\u00a0to the users. The design focused on opening the building up to the viewer in an interesting way, both outside and inside.<\/p>\n

\u201cA softer and more inviting environment has been created with terraces and the mushroom-shaped columns near the main entrance. The caf\u00e9 with mushroom shapes in the middle of the station hall also makes the space feel smaller and softer.\u201d\u00a0 \u00a0<\/span><\/p>\n

Exceptionally challenging conditions highlighted the importance of excellent designs \u00a0<\/span><\/h4>\n

Sweco\u2019s structural engineers were responsible for the main structural engineering, steel and concrete element frame design and complementary steel structures of the station building and\u00a0connected office towers. \u201cStructurally,\u00a0Tripla\u00a0was an exceptionally challenging but also an extremely rewarding project,\u201d explains Sweco Structural Engineering Project Manager\u00a0Anne Lindblad<\/strong>.<\/p>\n

\u201cConstruction was carried out above the tracks and on the nearby\u00a0platforms. There was little room for new structures, which is why old ones were enforced and used as much as possible,\u201d Lindblad explains.<\/p>\n

Railway traffic, in particular, was\u00a0challenging to the design.\u00a0Tens of thousands of people travelled through the site each day.\u00a0Exceptionally challenging conditions highlighted the importance of excellent designs. Work in the platform areas was carried out\u00a0during the night in order not to disrupt train traffic.<\/p>\n

\n
<\/i><\/figure>\n

\u201cWe were unable to be on call at night, so our designs had to ensure that there was no need to contact us from the site and the need for adjustments was minimal,\u201d Lindblad says.<\/p><\/blockquote>\n

Meaning of cooperation emphasised in projects with multiple parties<\/h4>\n

YIT Construction Project Manager\u00a0Kimmo\u00a0Assmuth<\/strong>\u00a0explains that the most challenging factor in the project was the large amount of interest groups.\u00a0Tripla\u00a0is a hybrid project combining offices and commercial\u00a0premises with public station areas, meaning\u00a0a large number of\u00a0interest groups from the City of Helsinki to commercial operators.\u00a0In order to coordinate the views of all parties, good conversation is required.<\/p>\n

\u201cDiscussions where we strived to find the negotiable and non-negotiable issues for each party were particularly fruitful. We never lost sight of the big picture and have all held on to the shared goal,\u201d\u00a0Assmuth\u00a0says.<\/p>\n

Although Sweco was responsible for the\u00a0station building, it is still tightly connected to the shopping centre and the station square. Several interfaces between different sections and operators needed to be coordinated, which meant seeing the\u00a0project as a whole.<\/p>\n

Ojalammi, Lindblad and\u00a0Assmuth\u00a0agree on good and close cooperation being the key to success.<\/p>\n

\u201cThe complex design work was carried out carefully. It included a great deal of expertise and top specialists from different fields. This was teamwork to the very highest degree, collaboration and working together,\u201d\u00a0Ojalammi\u00a0says.<\/p>\n

\u201cEach party understood that this is an exceptionally challenging project. This shared understanding helped us work together and solve issues in collaboration,\u201d Lindblad says.<\/p>\n
