DESCRIPTION
BIM Show Live 2014 - 4D BIM: successful implementation at Gravesened Railway Station, Oakwood GravesendTRANSCRIPT
4D BIM: Successful Implementation at NR Gravesend Railway Station
Christopher Brown – Managing Director, Oakwood Engineering
David Lindsay – Senior Delivery Manager, Network Rail
Project Overview - Scope £19.137m
• Remove the existing footbridge and water tower base
• Construct a new single span footbridge to replace the old footbridge
• Work during the 15 Day Blockade– Complete the new footbridge with lifts serving all
platforms– Remodel track and signalling layout throughout the
station– Extend existing Platforms 1 & 2 and construct a new
Island Platform & Canopy– Changes to the Station Systems (PA, CCTV,
Customer Information, etc.)– Changes to the Train tracking & control system at
Ashford Route Control Centre– Changes to the on-board train communications and
door control systems– Changes to the Channel Tunnel Rail Link Route
Control System for services to HS1
15 Day Blockade Stats
• 5,000m³ of new ballast• 1,060 new sleepers• 982m of new running track• 1,463m of renewed conductor
rail• 400m of realigned conductor rail • 120m of platform extensions• 85m of platform reconstruction• 275m of new island platform• 1 new buffer stop
Reasons for Using this BIM Strategy
4D BIM Modelling:
• Programme: Deliver On Time• Safety: Paramount
• 90 days of work condensed into 15
days
• First multi-disciplinary/trade 15 Day
Blockade
• 250 people per shift 24/7
• A step change to the ‘standard’ PM
packages
Project Collaboration
‘Nuts & Bolts’ Meeting: complete discipline collaboration
• Chaired by Construction Manager
• 4D Virtual Construction Model centre stage
• Multi-disciplinary design teams
• Multi-trade construction teams
• Site Management: access, compounds & storage
• Logistics Planning: engineering trains, plant & material delivery
• Planning Team: P3e ~ circa 50 reviews
• Safety Team: safe work zones, workforce deployment
• Risk Management: Quantifiable Schedule Risk Adherence
• Project Management
• Peer Reviews: visual project overview in 5 minutes ~ circa 30 reviews
Utilising the 4D Virtual Construction Model as a motivator for cross discipline collaboration significantly enhanced cross functional teamwork

Implementation of 4D
• On site collaboration – healthy breeding ground• Maintains normal working practices – 2D design
and Primavera P6 programme• Planning protocols• Interoperability – utilise existing 3D models / data• Level of detail requirements• Establish component library• Training• Hardware and software

Dynamic Clash – Access To Passenger Hoists Blocked By Temporary Prop
Dynamic Clash – Crane Prevents Jump Form System Progressing

Model Uses & Value Added - Safety Meetings
• The 4D Model was used to have a full safety review which resulted in implementing addition safety staff and methodologies.
• ‘Safety zones’ were identified and ‘safety supervisors’ were appointed and were dedicated for each area.
Model Uses & Value Added - Communication & Collaboration
• Workshops were held to allow the project team analyse the 4D model.
• The use of the model boosted project knowledge and facilitated input from all members to gain an optimised solution.
Model Uses & Value Added - Communication & Collaboration
Signal Sighting
Logistics Planning
• Site Inductions / Safety Briefings• Communication tool to all stakeholders, i.e. TOCs, FOC, Local
Authorities, Ashford Signalling Centre.• Consents Management - Road closures, car park closures and
haulage plans were accepted on the first applications• Design Management and Coordination
The Blockade
• Gale force winds and heavy rain during the first three days
• 100 hours lost due to weather• Work site described as ‘carnage’• 4D model was a key tool to mitigate against lost
time• Hours were steadily ‘pulled’ back through re-
scheduling• Re-scheduling very efficient as all parties were
aware of the work interfaces via the 4D Model
Planned v Actual
Planned @ 05.00 hours, 27th Dec
Actual @ 09.00 hours, 27th Dec
Project Outcome
• Completed on time with 1st train leaving at 04.33 on the 6th January
• No lost time to injuries
• No Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDORS)
• No lineside neighbour complaints
• No penalty costs - £1.625m/day
• No reputational costs/litigation
Lessons Learned
It Works• Ownership and dedicated resource to manage the push/pull of data
• Establish as early as possible/practical
• Trust the visual output and allow for revised programming
• Use a part of the Project Management ‘toolbox’
• KPIs to collate ‘hard’ factual evidence: BIM = ‘Bloody Impossible to Measure’
• Motivator for cross discipline collaboration to enhance cross function teamwork
• Employed by all disciplines; design verification, construction verification etc.
• Enhanced communication: better engagement with Stakeholders
• Capture all interdependencies for a holistic project delivery
• More detail = more data = more modelling = more processing time

Summary
Enhanced Project Delivery• Schedule, Cost, Quality & Safety
Should be part of the ‘standard’ PM Toolbox
Still having to ‘justify’ the benefits
