BIM Enabling Construction: Victoria Station Upgrade Context 2006: Why BIM? Managing the challenge From design to construction and beyond Pushing the envelope
Context: Why VSU is required? Heavy congestion and station closures during peak periods Current 80m+ passengers/yr - forecast to rise to 100m/yr by 2016 Major London transport interchange No step-free access Victoria Line Upgrade: more trains - faster service
Existing AM peak congestion End loading and narrow platforms leads to congestion... Lack of escalator capacity leads to blocking back to gateline... Gateline control leads to congestion in ticket hall... Station closures Congestion on Network Rail concourse
Scope and benefits Enlarged South Ticket Hall, greater circulation area New North Ticket Hall Reduced journey time Reduced station control Improved ambience Step-free Access Better emergency access Benefit/Cost Ratio = 6.9:1 Compatible with future third party developments Catalyst for Victoria area regeneration
Key challenges Ground Conditions, Complex Utilities, Limited Clearances to existing assets, Limited Access, Interface with Highways, WCC, Developer, Listed Buildings. Major Expansion on live railway, Logistics, NR & Ops Interface. Listed Buildings, Highways. Live Railway, Ops Interface, Optimise Possessions Network impacts, Limited Clearances. Phased Construction Under Carriageway, Traffic Management, Logistics, Developer Interface, Listed Buildings.
2006: Why BIM? Spatially complex Numerous interfaces Need to minimise rework / programme risk Potential efficiencies for construction Potential to support whole life asset management Collaboration essential BIM recognised as a key requirement by LU - five years before many other major clients
Why BIM? - Interfaces Civil engineering Geotechnical engineering Structural engineering Tunnelling Lighting Project controls Fire engineering Mechanical / PH engineering Requirements Electrical management engineering Permanent way Pedestrian Health and safety EMC modelling Monitoring Lifts and Document escalators control Human factors Legal Assurance RAMS / FMECA Traffic management Noise and vibration Architecture Communications Environmental
2006: Why BIM? District & Circle Victoria Circle development WDLS STH piles NTH piles
Managing the challenge BIM execution plan defining: CDE and workflows Model ownership Engagement of project partners Model purpose Appropriate level of modelling When to start modelling When to use 2D
CDE federated model approach
ProjectWise setup Single Source of Truth Supports Project Templates Standard Compliant File Naming Structure Standard Workflow for WIP, SHARE and PUBLISH Managed Workspaces with standards checking (CAD QA)
Workflow Manages the WIP and Share collaborative production for architectural, engineering & construction information CDE - WIP CDE - SHARED CDE - PUBLISHED Work in Progress Content Check Approve for Sharing Shared Approve for Publication Shared Rev.Ver: P01.1 Status: S0 Rev: P01 Status: S1-S4 ProjectWise
From design to construction and beyond
Space proofing
Clash detection
Clash detection
Interoperable analyses
SCL tunnel stress analysis
Laser scans imported to model
Rapid prototyping
Virtual construction parametric detailing Reinforcement modelled with associated metadata
Design for operation and maintenance
Pushing the envelope: ground treatment Clashes and voids eliminated before site works
Innovation and adding value
Digital setting out Advanced Excavator Control System works directly from 3D design data
Automation facilitated Direct bar schedule export/import
Potential for lifecycle management Capital Initial Cost Energy Inspections Cleaning Life Cycle Cost Occupancy Asset Replacement Redecorations Reactive maintenance Planned maintenance
Future developments - augmented reality RFID smart tags for asset management Visualising hidden assets
