Session 1.3
Application of Digital Engineering (DE) in the water sector
During this session, Farzam will discuss about positive impacts of implementing DE mindset and approaches in the Water sector. He will describe how digital data created via a variety of authoring tools through collaboration on daily basis makes the boat goes faster. He also will outline development of digital data maturity that commenced from design, progressed during construction and fully advanced during operation phase.
Synopsis:
Auckland is expanding rapidly. Essential infrastructure needs to keep pace with this growth, including the water supply network. That’s why Watercare utilised the Enterprise Model (EM) with its culture of collaboration to meet the challenge. The Waikato River to Redoubt (R2R) programme commenced to deliver an additional 50 million litres of treated water per day from Waikato River to Auckland. The fast-track nature of this programme, combined with an agile delivery model, presented several challenges to design and construction teams. The programme needed to be designed and constructed in parallel and within 12 months’ time frame to meet Watercares target operational date in line with predicted lake storage forecasts. Watercare, and its EM partners recognised the criticality of implementing effective digital engineering (DE) processes to achieve the outcomes of the programme. To implement a successful DE method, an automated process was developed to coordinate more than 80 models and special files daily. A geospatial system was created for the project, enabling flawless programmed daily collaboration between different models developed via a diverse range of tools, such as Revit, Plant3D, Civil3D, 12d, E3D, Navisworks and Recap Pro. DE helped the design and construction teams to coordinate continuously. This collaboration in the digital space enabled the construction team to provide rapid and efficient feedback on the practicality and constructability of the design information. Verifying models was another initiative implemented for the Waikato R2R programme which significantly reduced the total number of required drawings. Coordinated and verified models provided digital data for FCC and FH, enabling digital construction. Construction teams were empowered with information that was verified, digitally georeferenced and could be imported to machine controls. Machine controlled excavation and construction enabled FCC and FH to accelerates the earthworks, construct efficiently, and reduce overall fuel consumption of machinery. To enable digital delivery of asset and as-built information, the DE team worked with Watercare to develop an asset data schema and as-built model specification. It assisted to upgrade design models to as built with respect to construction programme. It also supported creation of digital asset information that is required for the operation phase and also can be utilised during life cycle of assets.
