Building Information Modelling (BIM) Becoming common for projects to be designed in 3D BIM
Ready or not, the construction industry is rapidly moving
away from traditional 2D CAD design tools and toward this
modern method of design
UK market is moving toward BIM compliance
Building Information Modelling (BIM) 3D: intelligent object building model for spatial coordination
4D: Construction Time and Scheduling
5D: Cost
6D: As-Built Working Model for Maintenance and Building Life Cycle
Possibly More Levels to Come
Level of Detail(LOD)
Typically, Too Much Information (detail) is provided for sub-
contractors in the working model
High LOD = very large files (> 1GB!)
Requires a significant investment in hardware and training
Ideally, Extract only Trade-Specific information from model
No industry standard for BIM Levels!
Other standards and levels: COBie (0 – 3), 1-4, G0 – G3, & more…
Why Change? Why should our industry move away from traditional design tools?
Why should we abandon years of investment in software and training?
Mainstream Architectural BIM software is very powerful, but
somewhat limited for a fire sprinkler designer
No welded outlets
No complex hydraulic calculations involving unlimited loops,
pumps, multiple water sources, and more
No curved pipe
No stocklisting for fabrication
Massive file sizes : workflow slows to a crawl
Limitations of 2D CAD – “The Hammer” “When all you have is a Hammer, everything starts to look like a Nail”
Dependent on a command-driven, layer-dependent 2D CAD engine, which
is not BIM
The 3rd dimension must be constantly thought about since it is not on the
screen during design and within the design program
Requires training for 2D CAD engine, the fire sprinkler design add-on
program, a separate coordination program, and possibly the program
used to create the building model
No internal intelligence of elements
Draw with lines, blocks, and attribute tags (electronic hand drafting)
CAD = Computer Aided (Hand) Drafting
Limitations of 2D CAD
• No immediate feedback for spatial coordination – info must be sent to:
• External coordination program does not allow modifications, hydraulic
calculations, or fabrication stocklisting
• Time consuming back and forth (2D – 3D) process

Collisions?
Create 3D model, then open and
view in coordination
program
All revisions must be made in 2D design program – repeat process as many times as necessary until design is collision-free

The challenges of 3D building plans
• Increasingly complex buildings

The challenges of 3D building plans
The same building in 2D
BIM for your Business Model
• Resisting this only serves to stifle innovation and limit your
company’s flexibility. Both are bad news for a Business Model.
• What does all of this mean for your Business Model?
• Transitioning to modern technology before your competition does
will allow you to acquire or maintain a competitive advantage.
Business Model Analysis – The Kodak Corp.
• Perfect example of a company resisting change.
• Initially ignored the shift away from film and toward digital imaging
• Ultimately cost them their position at the top.
• Massive legacy costs in hardware
• Skepticism and dismissal of new technology
• Instead of a bigger and better hammer, a completely different tool
was required
Benefits of 3D BIM – “The Anti-Hammer Device” a.k.a. The Right Tool for the Job
• BIM is more than just nice looking 3D pictures or models.
• Improved system design through better collaboration with all trades
• Coordination becomes a Team Effort
Benefits of 3D BIM – “The Anti-Hammer Device” a.k.a. The Right Tool for the Job
• Risk is reduced by eliminating unknowns
• Increased accuracy in ordering materials and fabrication
• Delivery of products and services are accelerated through better
efficiency
• Fewer changes on job site – less wasted material and labor
(Increased Profits)
• Better predictability of costs and scheduling – again, due to the
elimination of unknowns
BIM for Fire Sprinkler Design
• Instead of lines representing pipes, blocks for fittings, inherent properties
instead of attribute tags, full BIM compliance requires intelligent parts in a
three-dimensional model. This is the “I” in BIM. Without this, the model is
just a 3D picture.
• Intelligent parts contain the product data sheet, hydraulic properties,
weight, cost, and more.
BIM for Fire Sprinkler Design
• Each parameter can be changed, which changes the object’s
appearance and behavior. For example, a check valve would behave
exactly as its real world counterpart would. If it’s oriented in the
wrong direction, the clapper within the valve should close and not
allow the flow of water in the opposite direction.
Water Flowing
No Water Flow
BIM for Fire Sprinkler Design
• Fire pumps, water storage tanks (including water level information to
establish QMax and QCap data), fire sprinklers, hose valves, etc.
should all know their role in the system and interact with each other
appropriately.
