Why BIM?

www.logdesign.rs

• Expert from the European BIM Task Group

Handbook has researched:

• The European construction sector has output of

€1.3tn (trillion)

• It is approximately 9% of the region’s GDP

• It employs over 18 million people

• 95% of them are employed by small and

medium sized enterprises (SME)

• It is one of the least digitalized sectors with flat

or falling productivity rates.”

• The aim: Planning a build before any

machinery hits the ground


Construction sector –where everything begins

• Bad coordinated design documents

• Inaccurate/Incomplete Plans and Specifications

• Everyone wants to attribute risk to someone else

• Change in orders and reworks

• Schedule is irrelevant

• Delays and cost overruns

• Claims & litigation

• Risks in construction

• Slow exchange of documents

• Tight profit margins

• Subcontractors make up money on change orders


Typical problems in construction

• 30% projects do not meet original concept or budget

• 92% of clients said that designer’s drawings are not

tipically sufficient for construction

• 37% of materials used in construction become waste

• 10% of the cost of projects is typically due to change in

orders

• 38% of carbon emissions are from buildings, not from

cars

• 42% of world produced electrical energy consume

buildings (source OECD*)

*The Organization for Economic Co-operation and

Development (OECD)

What is BIM?

www.logdesign.rs

BIM very simply is …• “A digital representation of the physical and functional characteristics of a

building that is shared/used by all stakeholders to eliminate waste and increase efficiency.”

BIM - Building Information Modelling

• BIM is not about the B and the M it is about the I

• Information is the key

BIM definition• National BIM Standard Definition of BIM

• A Building Information Model (BIM) is a digital representation of physical and functional characteristics of a facility. As such it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward.

• A basic premise of BIM is collaboration by different stakeholders at different phases of the life cycle of a facility to insert, extract, update or modify information in the BIM process to support and reflect the roles of that stakeholder. The BIM is a shared digital representation founded on open standards for interoperability.

Prejudice about BIM

• My costs will increase if I get into BIM – FALSE

• There is a learning curve

• Payback is less than 6 months

• Technology changes so fast it intimidates us – TRUE

• 1992 First Commercial text message has been

sent

• Today the total number of text messages sent

and received every day exceeds the population

of the planet

• In 2006 2.7 Billion Google Searches every month

• Today there are 31 Billion every month

• What did we do B.G.?


What did we do before BIM?

“Give me six hours to chop down a tree, and I will spend the first four sharpening the axe.”

Abraham Lincoln


“The problem is never how to get new innovative thoughts into your mind, but how to get the old ones out.”

Dee Hock, VISA founder

BIM advantages

www.logdesign.rs

BIM advantages

• Powerfull database for building lifecycle

• Real time designing

BIM advantages in %

• 69% improved collective understanding of

design

• 62% improved overall project quality

• 59% reduced conflicts during construction

• 56% reduced changes during construction

• 44% faster Client approval cycles

• 43% better cost control (predictability)

WHAT’S REVIT?

www.logdesign.rs

REVIT – 3D & real time designing• Revit® software is specifically

built for Building Information

Modeling (BIM)

• Includes features for:

• architectural design

• MEP design

• structural engineering

• construction


REVIT MEP

• Mechanical

• Electrical

• Plumbing


REVIT - anytime & anywhere


• A change anywhere is a change

everywhere

• In Revit software, all model

information are stored in one place.

• As result, any information that gets

changed are effectively changed

throughout the model.

2D, 3D, sections, SLD, BoQ, BoM


REVIT - anywhere & everywhere

REVIT advantages

• Draw more precisely and quicker

• Concentrate on the building instead of the drawing

• Get rid of paper by electronic documents

• Let repetitive work be done by the machine

• Let “intelligent” functionality take care of certain tasks

(automation)

• Improved quality of the construction drawings (CDs)

• Reduced time to prepare the initial drawings and final

CDs

• Quantities and shared properties of materials are

easily extracted for cost estimating
