Design still drives the process


BIM complements the design process


Intelligent optioneering and manufacturing


More time to design less time documenting

BIM: What we see

37

Communication between the engineering office and his partners increasingly important: Architect, Contractor, Fabricator on the basis of a 3D model

Problems when parties dont use the same software as the engineer

Contracts depend on the Engineer being able to communicate with multiple 3D Modelling solutions or risk losing contracts

Most clients dont want to change their software, they have what they regard as the best solution for their business

The solution: Open BIM


SOFTWARE PROVIDER


BIM: Exchange structural model or analysis model

Two possible approaches for the model exchange between CAD & CAE software 1. Exchanging the analysis model

2. Exchanging the structural model (=Reference model)

1. Analysis model historical first approach Only possible if the CAD s/w supports an analysis model: Tekla, Revit The CAE s/w must use proprietary links and maintain them The user of the CAD s/w creates the analysis model The analysis model is sent back and forth

2. Structural model current approach, Open BIM Based on IFC format ISO standard For all CAD s/w supporting IFC: Allplan, ArchiCAD, Vectorworks, Revit, Tekla,

Bocad, DDS CAD, etc.

Developers focus on supporting 1 quality format, IFC The draftsman focuses on his model, the engineer focuses on the CAE model The reference model is sent back and forth


SOFTWARE PROVIDER


Open BIM The Vision

Clients can Choose the Best of Breed Solutions

No need for new software for each new project

One design program can be used to collaborate with

other project offices no matter the complexity of the

structure

Independent upgrade cycles

Intelligent Workflow = Less Errors

Scia Engineer is the only Structural Analysis and Design Software to fully

support the Open BIM process.

The following BIM tools are available:

1) Certified IFC 2x3 Import & Export

2) True analysis: Structural model and analysis

model in the same project

3) Member recognizer to convert reference

objects into equivalent analysis objects

4) Alignment to create a clean and connected

analysis model

5) Model Update to support revisions and

coordination

Pathology scheme won in 2011

Given option to use BIM

Jumped at chance

Full design team (architect/structural

engineer, M&E engineer, contractor)

willing to try BIM

Contractor was kind & stated you can go

back to 2D phew!

Lead-in

Inaccurate

Masked issues

Visual only

BIM Development

Generic modelling

Low level of development

Unintelligent limited data but sufficient to meet protocols

We became aware very quickly that

the 3D team was ahead of the 2D

team

The images and results from the 3D

model were noticeably quicker and

more accurate

The 3D images were conveying the

design better

We took the decision to stop the 2D

team and apply all resources to 3D

this then delivered the planning

drawings via the model

Common Exchange IFC

Luck?

Learn?

Feedback?

Did the contractor want IFC? Not really, they wanted native file format but it

soon became obvious there were three authoring platforms in the team.

NATIVE MODEL

Test prior to issue very important

Justification it works

Pre-cast concrete deck

Pre-cast concrete stairs

Pre-cast concrete lift core

Pre-case concrete twin-wall

Did it all work? YES but no.

IFC geometry issues

Demonstrates necessity to

validate

Time needed to fix issues

Be proactive not reactive

Do not be overly reactive to BIM

Collaborate share learn

Validate

Dont be too hasty

Interoperability testing

Put yourself out there you will be surprised

just how much help is available

Engage with the wider BIM community
