Lessons learned & feedback from the field5

Challenges and rewards

Difficulties

• Quantifying the ROI • Convincing the stakeholders• Change management• Management of training• Quality of the project management /

contract management• Poor implication by sub-contractors

Advantages

• Better quality of construction work• To try it is to adopt it• Splitting LOG from LOI improves

user experience• Easier commissioning with sub-contractors• Improvement of Health & Safety onsite

> better identification of risk situations> Automation for riskier activities

• New opportunities with > Drones> Scans> Robots> IOT

Lessons learned

Digital

• open BIM and split of LOG / LOI• ICT coordinator• Right software for the right need• BIM execution plan

Organization

• Each partner has their own model• Clear understanding of new roles• Voluntary basis and team training

Collaboration

• Workshop to define project use cases• Validation on 2D printed documents (issued from 3d models)

Risks management

Digital• Quality of softwares• Availability and compatibility of the releases of softwares• Hacking: network, models, data base…

Human• Actors or contributors authorisation / accreditation• Modelling without understanding• Blind trust in softwares and their results/reports

Common sense• Wrong understanding of the user needs or user behaviours (comfort, mobility, energy)

Contract• Organization of the BIM management and related interfaces

Toward a Professional Certification: buildingSMART
