Bentley Technology Drives Joint Venture’s Collaboration on E4 Stockholm Bypass - 1

Project Summary Organization: AECOM Solution: Megaprojects Location: Stockholm, Sweden Project Objective: • An energy-efficient transport system that provides efficient services in metro areas, and a robust and reliable infrastructure. • A bypass around Stockholm for the European Highway, comprised of a 21-kilometer motorway incorporating 18 kilometers of twin-tunnels and six interchanges. • Full compliance with environmental requirements, including construction of a majority of the route underground to mitigate impacts on six natural and cultural reserves. Products used: Bentley Navigator, InRoads®, MicroStation®, MXROAD, ProjectWise® Bentley Technology Drives Joint Venture's Collaboration on E4 Stockholm Bypass AECOM and AF Consult Leverage Power of BIM Methodologies for Integrated Project Delivery Fast Facts • Using Bentley's 3D modeling and collaboration applications, the joint venture designed the world's second longest road tunnels, mitigating environmental impacts during construction. • By 2035, Swedish Transport Administration Trafikverket estimates that the Stockholm Bypass will be used by approximately 140,000 vehicles per day. • The successful application of BIM processes led Trafikverket to develop a national strategy for BIM implementation on future projects. ROI Using ProjectWise with Bentley's BIM solutions facilitated information modeling, management, and mobility on this SEK 27.6 billion megaproject, increasing efficiency and enhancing data integrity. The streamlined, collaborative process for BIM review and checking produced correct, well-thought-out solutions, resulting in significant time and cost savings. ProjectWise implementation will carry forward through construction and into operations, enabling better asset management and lower operating costs. Megaproject Sets BIM Standard This SEK 27.6 billion multi-discipline project required the AECOM and AF joint venture (JV) to design 18 kilometers of twin tunnels for the Stockholm Bypass, a 21-kilometer motorway linking southern and northern Stockholm, Sweden. Intended to reduce the impacts on sensitive natural and cultural resources, the underground link will be the world's second longest road tunnels, with their mainline reaching a maximum depth of 100 meters. Given the magnitude of subsurface work involved, the project required 19 million tons of rock to be excavated during construction. The JV used an integrated project delivery (IPD) method, fielding a team of 560 designers in 19 disciplines across nine countries. Powered by Bentley technology, building information modeling (BIM) methodologies streamlined the collaborative design process and supported the resolution of technical, construction planning, information management, and environmental challenges. The successful demonstration of IPD incorporating BIM processes led the Swedish Transport Administration (Trafikverket) to spearhead a national strategy for BIM implementation. Massive Civil Engineering Challenge Trafikverket investigated various alternatives for the European Highway (E4) to link southern and northern Stockholm while bypassing the city itself. The chosen alignment will support growth and development in the region, unify the labor and housing markets, and relieve traffic congestion on the Essingeleden motorway, which today operates at twice its design capacity. AECOM and AF Consult, a Swedish engineering and consulting company, formed a joint venture to undertake the Stockholm Bypass project's biggest design contract—FSK02 Rock Tunnels—one of the largest civil engineering undertakings in Sweden. The twin tunnels each comprise three lanes with hard shoulders, as well as safe evacuation passages and tunnel operation facilities. In addition, three major underground interchanges required connecting tunnels for exit and entrance ramps. During construction, separate access tunnels and crushing chambers were needed to efficiently transport the 19 million tons of rock excavated from the site. Temporary jetties had to be installed to transport 50 percent of the rock by conveyor to sea transport. A foremost consideration during construction was minimizing adverse effects on local residents and the environment, which included sensitive areas such as a UNESCO World Heritage site. This massive undertaking presented countless engineering hurdles, as well as design process, workflow complications, and project information management challenges. With hundreds of designers working in multiple countries, the various design teams generated more than 50,000 documents during the design phase for the FSKO2 Rock Tunnels contract alone. Effective communication and collaboration were paramount to successfully delivering the design. Bentley’s BIM solutions facilitated 3D modeling, collaboration, and integration among the diverse project teams, with ProjectWise® as the common data environment. Interoperability and Information Mobility Trafikverket used BIM to standardize information flow in design and construction, paving the way for its use on all future projects procured in the Swedish construction industry. AECOM - AF joint venture proposed a strategy that emphasized interoperability and information mobility as the way to ensure accessibility of the right information to the right people at the right time across the entire project lifecycle. The JV also advocated for IPD, emphasizing a collaborative, cooperative way of working to produce technically comprehensive designs.

"Bentleys software allowed the AECOM -AF joint venture team, which consisted of more than 560 people working across nine countries, to successfully deliver the design of the Stockholm Bypass, one of the largest infrastructure projects in Sweden. It is difficult to contemplate how a projectof this magnitude and complexity could have been delivered without the use ofbuilding information." — Kenneth O'Hara, ProjectDirector, AECOM Find out about Bentley at: www.bentley.com Contact Bentley 1-800-BENTLEY (1-800-236-8539) Outside the US +1 610-458-5000 Global Office...
