3D highway Design– from an Early Stage to the Construction Site Tuomas Hörkkö, Vianova Systems Finland Oy
Generally about digital 3D-models • 3D-models used many years in different type of projects • Earlier mostly focus on visualisation and presentations • In Nordics more and more focus to use 3D-models as a part of the integrated planning • ”Engineer models/Coordination models” in use – the future way to work
Summarizedhistory ” Engineermodels” • OPS (Public PrivatePartnership) 3 – Skanska • HW 44 Kleppe, Stavanger – Skanska • ÖstreTangent – Norwegian Road Administration • HW 150 Ulven-Sinsen – Norwegian Road Administration • Kolsaasbanen Oslo and Baerum – KTP - Railway • HW 6 NordreAvlastningsveg, Trondheim – Skanska
Engineer models - Keypoints • Much experience in different projects – use it as a plattform in projects! • Common rules/data delivery important for all disciplines in a complete project • Everyone agreed routines before start • Start to use this from day 1 – be familiar with the way to work – meetings in the process with correction • Education with every responsible for delivery • Important with focus on this from top to bottom in the companies
Engineer models - generally • Generally conditions: • Mirror of relevant data that the project need to build. Not necessary with every detail • All parts of the project shall be in the model over and above the ground • No manual finishing • Updated continuous as a part of the design work • Every member get access to the updated model continous in a webhotel
Engineer models - Enviroment • Software: • Autocad / Novapoint Virtual Map • Different Novapoint-modules • Important functionality : Groups and viewpoints Show it in demo later
Engineer models - Advantages • Easy way to check the quality of the planned solution, higher quality of the solution • Collision detection • Optimization of the total solution • Multidisciplinary communication • A basis for the building contractors
Engineer models - Process • Short about the process: • Continuous delivery to the VR-model when something have changed – rules defined • Presentation in the frequently meetings (frequency 2-3 weeks) • Used a lot in different meetings between the disciplines (as an example landscape, signs, light) • Common meetings for all disciplines with necessary correction • Part of the end result together with drawings and description
Demo : HW 150 Ring road 3 Ulven-Sinsen – Oslo • Big an complexed project • Used in the most complexed part (E22) • Multidisciplinary
Engineer models - experience • Today's software works - but it can (of course) be improved • Different interest from the discipline responsible – person and discipline culture • Routines and work flow must be optimized – and of course be followed • Easy to update the model with common configuration – again routines • Have been used a lot to multidisciplinary control • Important with collision detection – marked in the model – and followed up/changed • Many conflicts/errors lokalized – many iterations • Important with engagement and interest from everyone in the project (management, discipline responsible) • Good feedback from the customer • Save time and money!!!
Engineer models – next step • Important moments in the near future: • New handbook from the Road Department in Norway soon ready. Define the requirements for the planning process • Start to use this in every project. Big focus on this in this sector in Norway from everyone (Employer, Consultants, Contractors) • Continue to develop software adjusted to this way to work • It is not very complexed – but it have to be worked further on the structure/routines • Continue co-operation between companies and sectors – we learn from each other • ENGAGEMENT and will to change routines in each discipline I guarantee that it will be extremely fun to see your ”own” data as buldit before it is built
