AECOM Creates iModels Available to All Stakeholders on Thames Tideway Tunnel - 1

CASE STUDY Project Summary Organization AECOM Solution Water, Wastewater and Stormwater Networks Location London, United Kingdom Project Objectives • To create as-constructed information in a digital model shareable with project participants. • To prepare the project for handover back to the client. Products Used OpenBuildings™ Designer, ContextCapture, Descartes, gINT®, MicroStation®, Navigator, ProjectWise® AECOM Creates iModels Available to All Stakeholders on Thames Tideway Tunnel Bentley Applications Developed iModels and Housed Them in a Connected Data Environment Fast Facts • The Thames Tideway Tunnel project was developed under a European Union directive to reduce sewage discharge events. • Bentley's Connected Data Environment based on ProjectWise hosted project data, including construction models and drawings, for all eight sites. • With OpenBuildings and MicroStation, AECOM created a master design model for each site, viewable by all project stakeholders anytime. ROI • There are more than 1,100 users in the ProjectWise system, including more than 40 stakeholders. • As of October 2018, there were over 190,000 documents created in the central repository, with over 4,500 drawings and 1,500 models. • Users share information through defined workflows between all participants with access to the data 24/7 every day of the year. Reducing Sewage Discharge Events in the River Thames Designed by Sir Joseph William Bazalgette in the late 1800s, the London sewerage system needed a significant upgrade. The system was originally designed for a population of 4 million people; today, the region's population has doubled and continues to grow. The original system is no longer suitable given the increase in waste, and millions of tons of sewage are spilling into the River Thames' tidal section annually. With even slight rainfall triggering these sewage discharge events, the GBP 4 million Thames Tideway Tunnel project was developed under a European Union directive to reduce the events. There are approximately 50 events each year taking place along the river. The primary objective of this project is to alleviate pollution from the London sewerage system into the River Thames during periods of heavy rainfall. When completed, the Thames Tideway project will reduce sewage discharge occurrences to approximately four per year. Managing a Complex, Multifaceted Project The Tideway project is divided into three contracts: east, central, and west. AECOM is the main designer on the central contract, which covers about 25 kilometers of tunnels and connecting tunnels between the towns of Acton and Abbey Mills in London. AECOM designs, builds, finances, and operates assets in more than 150 countries. With over 87,000 employees, it was ranked number one in transportation and general building in Engineering News-Records 2018 "Top 500 Design Firms." For the Tideway project, AECOM worked with the main works contractor, Ferrovial Agroman and Laing O'Rourke Joint Venture (FLO). AECOM was tasked with providing an integrated, multidiscipline service that includes tunnels, marine engineering, hydraulics, and health and safety for the project. The central contract includes eight sites, each one complex enough to be its own project. Currently in the construction phase, AECOM needed to create as-constructed information in a digital model to both share with all project participants and prepare for handover back to the client. The project team faced numerous challenges, the most notable being the large amount of people involved in the project. Each site had its own team and group of stakeholders that required access to information anytime and anywhere to make important decisions throughout the project's lifecycle. The large scale of the projects marine construction works also posed issues. AECOM needed to create a new profile to the river walls, as well as solve design issues where large gas mains were present close to the existing walls. Gas service, as well as shipping services, had to be protected during construction and after the project's completion. Creating a Connected Data Environment® for Project Data To keep everyone on the project informed and to avoid disturbing life in the surrounding area, AECOM used Bentley applications to design the central contract tunnels and map out construction plans. Bentley's Connected Data Environment based on ProjectWise was used to host the project and facilitate access to data for all stakeholders for all eight sites. It also housed all construction models and drawings to simplify the handover process. Data for both temporary and permanent works were accessible to all project stakeholders for easier decision making.
