Stage 04: Whole Lifecycle BIM Project: the story of BIM from design to use (Case Study)
Date: 2014-04-24, Track: Session 6
Head of BIM – Sir Robert McAlpine
Regional Director – IBSECAD
3d coordination to de-risk schemes
2012 business BIM strategy
5 key ingredients for the extent of implementation.
1 : project managers interest proportional to the success of BIM/VDC
2: buy in and willingness from all stakeholders
3: scale, scope and the complexity – maximise net lettable and floor to ceiling heights
4: contractual solution/position
5: aspiration and capability.
Aspiration : Maximise design validation. Reduce risk and increase transparency. Early coordination and clash detection. Safety. Sequence and constructability. Softer handover.
Capability : augmented using Ibsecad to upskill and achieve.
Level of detail was defined by the knowledge of sub contractor requirements.
The BIM savvy design team needed little encouragement.
Collaborative workshops to drive solutions were held weekly.
All stakeholders had representatives at meetings.
Gap checking for services as the system can not be tested until it’s closed.
Rodding eye access. Opportunity to capture before installation.
Sequence of install. Tablet site reviews. Areas assessed with trades prior to install.
Draw it once. Evolve to S/c and integrate FM
Hangers for MEP are in the model.
Procured equipment was added and updated in the model
Complete tender info before going to the market.
Soft handover – keep it simple
AIM – asset information model
Hyperlinked model, simple but it works.
In house laser scanning team.
Typical stage E. Excessive clashes. Lack of constructability during design. Inaccurate data drop.
Start earlier. Construction experience is vital
Earlier contractor involvement
Resolve clashes and constructable detail.
Key elements and areas done to a higher level of detail earlier.
Favourable contract position : design and build. Pre-con agreement. A team that had worked together before and brought together again.
FM team brought in as soon as you have a model.
No costing at this stage but models were used but it’s next stage of development.
