BIM‘Building Information Modelling’

BIM, is a way of describing a collaboration design process using computer model data rather than separate sets of

drawings.

BIM, is not a single software solution.

BIM, is a process of sharing model data between themembers of the Project Team using different software.

The aim is to use each piece of project data to a maximum effect reducing repetition and errors.

What is BIM?

BIM: Building Information Modeling

Model data is shared in order to strengthenthe coordination between disciplines andparties associated with the project.

DWG, DXF Low level, no object intelligence

ACIS (AutoCAD) Low level, extruded shapes

SDNF Medium level, object data (only for steel industry)

CIS/2 Medium level, Mainly object data(CIMSteel, AISC)

OpenBIM (IFC) Good level, mainly object data. (all industries)

Custom Links High level, fit for the purpose,(ProtaStructure –> Revit Structure integrator)

Accurate design decisions can be made earlier and faster

Big reduction in repetitiveworks

Reduction in clashing

Reduction in material waste

Benefits of BIM

BIM in Public Sector

*BIM is mandatory in publicly fundedprojects in many countries today, including:

USA, Norway, Finland, Singapore andmany more

UK (by 2016):

To reduce the capital cost and reducecarbon

Turkey:

Clients request in most of theimportant projects

Firms that fail to adopt BIM risked being ‘betamaxed out’ of existence.”

Paul MorrellUK Government’s Chief Construction Advisor

Hardware and Software Cost

Training Costs

Vital step in BIM transition

Transition from 2D drawings to 3D modelling

More qualified technicians/engineers are required

Designer/modeler needs to have detailed information about the project.

Compatibility and communication between different software platforms

Difficulties in Transition to BIM

Key Requirements for BIM to Succeed

The ability of software solutions to communicate with each other

A full appreciation of internal and externall processes

Good level of communication in the team

BIM Education and planning

Structural BIM

Structural Engineering firms has two main deliverables:

Design

Documentation

A pivotal role in the full adoption of BIM

Construction Documentation Modeling

Example: Autodesk Revit

A BIM platform for

architects,

structural engineers,

Mechanical/Electrical engineers

Used to create

Design reports

Construction documentation

Material listings

Example: ProtaStructure

Structural Engineering Platform for Code Based Design & Detailing

Communicates with Revit

BIM in Architecture

BIM in Structures

BIM in MEP

Code Compliant Design

Structural Engineer must comply with several codes of practice.

Code Compliant Design and Detailing

A single structural model that contains all data required toanalyse, design and detail a structure in strict compliance

with a selected code of practice

Design Codes: TS-500, EC2, BS8110, ACI, HK2004, CP65

Seismic Codes: TDY2007, EC8, IBC, UBC,
