IFC models shortened the design time of Nelostie bridges by months<\/h1>\n

The renewal of Finnish national road 4, AKA Nelostie, from Kirri in Jyv\u00e4skyl\u00e4 to Tikkakoski has been one of the largest and most advanced infrastructure projects in recent years. The new highway, which has been awarded a Tekla BIM award, includes 30 bridges, the design time of which was shortened by several months with the help of a digital process.<\/p>\n

Finland\u2019s longest highway, Nelostie, is one of the country\u2019s most important main roads for heavy traffic, stretching from Helsinki in the south coast all the way to Utsjoki in the northern border. The service level and safety of an approximately 16-kilometre section of Nelostie in Central Finland is currently being improved in the Finnish Transport Infrastructure Agency\u2019s Vt 4 Kirri\u2013Tikkakoski project. \u201cThis is a major project for us, the largest one in progress at the moment,\u201d says Project Manager Jaakko Taipale<\/strong> from the main contractor of the project, Destia.<\/p>\n

Pioneering information modelling eliminated work stages and saved materials<\/h4>\n

What makes the Kirri\u2013Tikkakoksi infrastructure project truly special is the pioneering information modelling utilised in it. At the request of the Finnish Transport Infrastructure Agency, the design, implementation and quality control of the project were carried out based on information models. The different parties of the project were provided with up-to-date and reliable information with IFC models, almost completely eliminating the need for 2D drawings. \u201cThese new tools provide us with a better understanding of the structure and eliminate unnecessary work,\u201d Taipale summarises.<\/p>\n

Thanks to these new tools, the highway was opened to traffic approximately 8 months ahead of schedule, and the design time of the bridges was shortened by about six months. \u201cWe saved a lot of time in the planning, when the external inspection of the plans and the approval of the Finnish Transport Infrastructure Agency were handled directly from the data model,\u201d says Project Manager Mauri Kuvaja<\/strong> from Sweco. Usually, external checks are carried out on paper drawings. In addition, the models also helped optimise material consumption. \u201cConcrete consumption was reduced by 11%, meaning over 1,000 cubic metres.\u201d<\/p>\n

The information models were also utilised at the worksites, allowing e.g. steel fitters to examine models of the bridges\u2019 steel reinforcements via a large touchscreen inside the site hut. \u201cAt the start of the project, we provided the entire project team with training on information modelling,\u201d says the principal designer of the bridges, Juha Litmanen<\/strong> from Sweco. The information models provided dimension and location data at the worksite and for the steel reinforcement plant. \u201cThis was a first in a Finnish bridge project. We managed to eliminate unnecessary work stages, and there wasn\u2019t a single mistake in the steel reinforcement deliveries.”<\/p>\n

The project also involved creating bridge maintenance models for Nelostie, allowing the new operating methods to provide added value for bridge maintenance as well. \u201cThe project proved the benefits of information modelling in practice, which I believe will promote the digitalisation of the entire infrastructure sector and the adoption of harmonised information model standards,\u201d Kuvaja states.<\/p>\n

Relying on the old and developing something new<\/h4>\n

The majority of the new Nelostie bridges consist of prestressed concrete block bridges, but the project also involved testing some new bridge technologies, such as element bridges, which have become rarer in Finland. In addition to these, the project included twin bridges, reinforced concrete slab bridges and two wooden Versowood cycling and pedestrian bridges.<\/p>\n

\u201cThese are examples of climate-sustainable bridge-building,\u201d Litmanen says. According to him, Sweco started the groundwork for the bridge designs in collaboration with the Finnish Transport Infrastructure Agency and the main contractor back in the project planning phase in 2018. \u201cWe chose the bridge types used in the project, allowing us to prioritise repeatability in the structural design and thus generate cost savings.\u201d<\/p>\n

In a design and build contract like this, close partnership between the client, the contractor and the design office is key. \u201cSweco\u2019s expertise was a great help in the bridge design, and the design work proceeded as planned and on schedule,\u201d Taipale says. Every bridge was also completed on time.<\/p>\n

In Mauri Kuvaja\u2019s opinion, one of the key success factors of the project was Destia\u2019s precise scheduling. \u201cThe contractor\u2019s ability to organise design and site schedules and work orders ensured smooth transport connections both on the old Nelostie and on the parallel road constructed for site traffic. Kirri is passed by 20,000 vehicles every day.\u201d<\/p>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":"
