BIM is a way to handledigital information of built assets.

It combines a digital twin of the assetand digital processes to

design, build and maintain the asset.

Why Open Standards?

”All the stakeholders should use the best tool for their job. In order to exchange BIM based information between these tools, we need an open, common data exchange format.”

Aulis Kohvakka, CEO of Senate Properties

IFC is the Open Data Exchange Format for Building Industry

IFC = Industry Foundation Classes (ISO 16739-1:2018, 2013, 2005)

BIM and different Project Types

▪ Design & Build▪ The objectives for BIM need to be specified with the same precision as other project goals.

▪ Client possibilities to influence to deliveries are limited after tendering.

▪ Traditional Tendering Model▪ Designs are mostly finished before tendering – no significant changes in construction phase.

▪ In order to get the best out of BIM, the Client needs to predict and specify how BIM is used in the construction. This may not be easy.

▪ Integrated Project Delivery models – design and construction overlap▪ Client should have clear vision of the BIM handover. Nevertheless, the IPD model gives certain

flexibility to adjust goals during the project.

▪ Split project leadership can lead to unwanted compromises regarding BIM.

How to improve the design and construction schedules?

Understand the status of BIM▪ Creating BIM = Creating the Design

▪ Scheduling the BIM work = Scheduling the Design work

Design how you Design▪ Challenge: Design of the design is a complex task

▪ Solution: Split the Design Task to modules than can be linked together

Verify the Schedule constantly▪ Compare the Schedule against the actual design status

▪ Analyse and react if there is a clash between the schedule and design status

▪ Make changes if needed

BIM in design and construction

What is the Project Type?▪ The more control you have over BIM, the better you can utilize it

Quality of the BIM is essential▪ The structure and naming conventions in models have to be logical

▪ How does your process (and software) handle design changes?

Communicate▪ Present the BIM based schedules to the whole design team (not just to the construction team)

▪ If you have any (technical) problems with BIM, (try to) solve them

Challenges

Documents vs. BIM▪ BIM process vs. document based process is an interoperability challenge.

Problems are solved with technology▪ Technology generates new opportunities but also new challenges.

Transformation▪ The roles and practices need to be changed together with technology.

▪ Transition to BIM is a revolution versus the change from blueprints to CAD.

Project Management▪ BIM changes schedules, roles and agreements.

▪ Design group is expected to generate results without supervision.

Unrealistic goals▪ By setting the goals too high, there is a risk that you fail to achieve them.

BIM in Practice

YES, BIM WORKS

▪ BIM has become an everyday tool in projects.

▪ Software are getting better all the time and IFC works in the daily routines.

▪ International standards and guidelines are improving the quality of BIM.

▪ BIM knowledge and skills are improving quickly.

CURRENT CHALLENGES

▪ Potential of BIM in maintenance and operations has not been fully utilized yet.

▪ Very little collaboration between building and infra structure sectors.

▪ Technology is developing rapidly – how to keep up?

▪ Traditional processes need to be revised in order to get best out of BIM.
