Session 1.2
Collaborative Digital Design and Construction in Infrastructure
Synopsis:
An in-depth look at design and construction focused digital activities on Melbourne’s SEPA level crossing removal project. The project has successfully managed design information in a rules based CDE, used computational design tools for rapid option assessment from early concept stage and used Open BIM for model exchanges across all disciplines.
We will also cover how project team were taken on a journey, how the CDE processes evolved, technology used, lessons learned and future developments.
Learning Objectives:
1. How to make Open BIM work for infrastructure using project data standards
2. Applying rules based CDE workflows for design and construction teams
3. Uses of computational design for rapid early assessment and bringing ‘stubborn’ rail disciplines to the table during detailed design
Body:
The presentation format will be a case study style presentation using slides and video clips. It is intended for anyone involved in Infrastructure project delivery, whether directly as a BIM Manager/modeller or indirectly as a Project Manager, Construction Manager or engineer.
It will explain how we met the challenges within civil infrastructure such as diverse tool sets, lack of digital experience, reliance on drawings for reviews, no defined IFC schema and lack of object-based design tools for design.
Topics will be explained with the intent of sharing our methods, our thought processes and hopefully inspiring other practitioners to push their projects further.
Subjects that will be covered and explained include:
How we used Open BIM and project data –
– Full use of Open BIM format (IFC) including ‘difficult’ Civil Infrastructure disciplines and landscaping
– How we standardised the project data parameters SBS, WBS, design packs, CBS to link design and program
How we used Computational Design:
– Early concept grasshopper testing options, rail over (viaducts), rail under (piled trenches) etc.
– Custom built Rail Platform design tool ?100 options in a day?
– Advanced processing of Lidar to enhance site topography, roof slopes and extract colours into Infraworks for stakeholder engagement
– Utilised Grasshopper to bring traditional 2D Rail disciplines into the 3D fed model (via IFC)
How we designed and built our Common Data Environment:
– Common data environment development of a ProjectWise rules engine for States and file visibility
How we digitised Collaborative review:
– The project has harnessed Revizto for capture of model reviews, interdisciplinary design reviews, fabrication checks and construction site red-lines.
– Enabled model-based Signal sighting technical reviews with MTM and fly-throughs.
How we increased digital awareness and culture.
– Big plasma screens loaded with Revizto and Navisworks, project team awareness ,IDC reviews and comment capture.
There will be honest lessons learned and details of what we have planned for the next phases, as well as time for questions.
The SEPA program is an alliance between Jacobs, Laing O’Rourke and MTM.
