Grontmij Uses Bentley Technology to Facilitate Information Mobility on Dual Carriageway Design - 1

Project Summary Organization: Grontmij Solution: Roads Location: Stockport, Manchester, and Cheshire, United Kingdom Project Objective: • Deliver detailed design, construction, and defects liability maintenance for a 10-kilometer dual carriageway. • Establish a common data environment that supports collaboration among 200 multi-discipline team members across six offices, and the realization of scheme goals. • Provide early contractor access to over 160 models, allowing stakeholders to develop a virtual construction sequence. Products used: Bentley Navigator, MXROAD, OpenRoads, i-model Composition Server, MicroStation®, and ProjectWise Grontmij Uses Bentley Technology to Facilitate Information Mobility on Dual Carriageway Design Federated BIM Strategy Streamlines Collaboration with Three Different Clients, and among 200 Multi-discipline Team Members Fast Facts • ProjectWise served as the common data environment, giving team members and stakeholders controlled access to project information and data models. • Integrating i-models with Bentley Navigator provided a process to analyze more than 200 clash detection rules during the design phase. ROI The project will contribute up to GBP 2,492 million in economic growth throughout the Greater Manchester and Cheshire East Reduced travel times, lower vehicle operating costs, and fewer accidents will save motorists an estimated GBP 880 million. A Pioneer BIM Initiative Grontmij, a design partner in the Carillion Morgan Sindall joint venture, pioneered a federated BIM methodology in the detailed design, construction, and defects liability maintenance of a 10-kilometer dual carriageway in Manchester, England. The GBP 100 million project runs from A6 at Hazel Grove to Ringway Road/Ringway Road West Junction, and includes a section of the A555, the geometric layout and signal controls on the A6 junction, four railway structures requiring a major interface with Network Rail, bridgework, utility diversions, and flight path constraints of the Manchester Airport. Grontmij initiated this project under an early contractor involvement (ECI) arrangement, and is expecting the completion of design and construction works by May 2017. Using a collaborative process powered by Bentley technology Bentley Navigator, MXROAD®, i-model Composition Server (formerly i-model Composer), OpenRoads, and ProjectWise®, Grontmij established an integrated modeling environment across its six offices—comprised of 200 staff supporting 15 disciplines—helping break down interdepartmental barriers and enhancing the model review process. The information mobility and integrated modeling capabilities of Bentley applications enabled cost-effective design with improved accuracy, fewer errors, minimal clashes, and fewer construction site queries, thereby reducing project time and costs. Supporting Three Clients The primary challenge involved working with three municipal authorities—Stockport Metropolitan Borough Council, Manchester City Council, and Cheshire East Council—each with different information requirements and regulatory compliance issues. All three municipalities were individually seeking planning permission for the proposed scheme. Together with the main carriageway, the scheme required construction of railway, roadway, bicycle, and pedestrian bridges; traffic signal installations; road lighting and culverts; utility diversions; and landscaping works. Four railway structures also required extensive interface with Network Rail to address land constraints, and at the west end of the project the Manchester Airport flight path constrained the project's vertical geometry. To ensure success for all parties, the multi-office project team established a common set of overarching scheme goals: define value and common objectives, establish a collaborative working environment, recognize and resolve disputes, take an open and transparent approach, ensure equal consideration for suppliers, and promote a culture of innovation and value management. The project delivery team determined that only a federated BIM methodology would enable project stakeholders to work in a truly collaborative manner. Unified Design Environment Harnessing Bentley's BIM advancement solutions allowed the Grontmij team to be innovative in an enhanced, collaborative environment, and seamlessly manage the risk associated with the disparate delivery team. Fully implementing a unified The GBP 100 million project included the geometric layout and signal controls on the A6 junction, four railway structures, bridgework, utility diversions, and flight path constraints of the Manchester Airport.
