Skanska Costain STRABAG JV Uses BIM Processes for Civil Works on Europe’s Largest Railway Project - 1

Project Summary Organization Skanska Costain STRABAG JV Solution Rail and Transit Location London, United Kingdom Project Objectives • To implement robust BIM processes to meet challenging client data and modeling requirements for civil works. • To establish a connected data environment and digital workflow system for an international, multidiscipline team. • To create a digital blueprint for future infrastructure projects after executing this project. Project Playbook AssetWise®, gINT®, MicroStation®, Navigator, OpenBuildings™ Designer, OpenRail™ Designer, OpenRoads™ Designer, ProjectWise® Skanska Costain STRABAG JV Uses BIM Processes for Civil Works on Europe's Largest Railway Project Leveraging Bentley's Open Applications in a Connected Data Environment Reduced Costs Fast Facts • A comprehensive 3D BIM approach involved contractors earlier in the HS2 high-speed rail network project. • Bentley technology facilitated a structured digital data approach that will serve as a blueprint for future railway projects. ROI • A connected data environment streamlined workflows and allowed for early detection of errors to save GBP 1 million. • Bentleys integrated BIM applications facilitated data extraction for ccurate material quantities and cost estimates, reducing waste. • Leveraging iModel technology shortened design review time by 20%, saving GBP 500,000. A New High-speed Railway High Speed 2 (HS2), the new high-speed rail network that will run through London, Manchester, and Leeds, is expected to be the backbone of Britain's transport network, tripling its capacity by carrying more than 30,000 passengers per day. At a cost of GBP 56 billion, it is the largest construction contract in Europe to date and, at a speed of 250 kilometers-per-hour, will have the fastest trains on the continent. The rail line spans 531 kilometers in length, with 46 kilometers of tunnels, hundreds of bridges, and numerous shafts and portals. This project is one of the most complex and challenging railway initiatives that the United Kingdom has ever undertaken. Tasked with saving the government GBP 500 million in digital efficiencies, HS2 is committed to applying global best practices in design and construction, setting strict data and modeling requirements in accordance with PAS 1192 BIM standards. Skanska Costain STRABAG JV (SCS) was contracted to perform civil works and bring worldwide high-speed rail experience to the first phase of HS2, namely the line running 230 kilometers north to south between London and Birmingham. The contract mandated early contractor involvement with the designers to formulate and achieve approval of a conceptual design scheme for 26 kilometers of high-speed railway within 14 months. Featuring 20 kilometers of tunnels, several bridges, and five kilometers of earthworks, the estimated GBP 1.5 million project presented engineering and coordination challenges to optimize efficiency and meet the client's digital BIM demands. SCS needed interoperable technology to implement a comprehensive, collaborative BIM strategy to accommodate the existing British railway systems and approximately 6,000 utility assets, as well as to coordinate a geographically-dispersed, multidiscipline team. Implementing a Robust BIM System The project team consists of six companies and over 550 staff, spanning four countries. "We have 59 nationalities, so quite diverse cultures on the team, and we like to think BIM is the common language we all speak," commented Peter Ruff, head of BIM for SCS. SCS digested the project requirements from HS2 and developed a BIM execution strategy that engaged the entire team, with modeling guidelines and procedures ranging from 4D construction management through logistics and operations. The team began by generating a content plan that defined the model breakdown and structure, starting with the asset to be added to the model, and then the elements to be incorporated. The contractors and designers created a library of components shared within ProjectWise through OpenBuildings Designer as the principal modeling application. Establishing a data library in one location enabled more effective workflows for all involved team members. This custom component library ensures that all elements are identical and that model data is based on predefined criteria, certifying consistency and accuracy for estimates, planning, constructability, and safety. Integrating OpenRail Designer and AssetWise during the early design stage allowed the team to align a fine level of detail within the 3D models that could be integrated with ProjectWise where everything is registered, documented, and managed, according to project milestones. Navigator facilitated model reviews using iModels to publish the information as a visual package with linked documentation that enabled better understanding of the scope of work for more informed decision making. Using AssetWise to link specific asset information directly to the design model facilitates an asset-centric approach to enable early involvement of operations and maintenance and sets the stage for full lifecycle BIM. SCS transformed its written collaborative plan into an integrated, robust BIM system that ensures consistency, accuracy, and efficiency with Bentley's interoperable BIM applications. Connected Data Environment Delivers Benefits SCS used ProjectWise and AssetWise to establish a connected data environment, providing the project team real-time access to trusted information wherever and whenever it is needed through Bentley's integrated modeling applications. "We wanted to make sure that everyone, designers and contractors, can use this information," Ruff explained. Using ProjectWise CONNECT Edition and other connected applications allowed SCS to explore new features such as Deliverables Management,
