Who We Are
Our Guiding Principles
Our Mission
To collaborate with clients to create the best building solutions for the
entire building lifespan.
Our Values
 Collaboration: Listening is not a spectator sport. We seek out ideas and
goals and build upon them.
 Creativity: We are driven by original ideas.
 Commitment to excellence: Attention to the details, while keeping our
eye on the big picture.
 Caring: Doing the right thing for our clients, our colleagues and our
communities.
 Our Vision
Always reinvent how buildings are imagined - and built.

The BIM Concept
The Current BIM Concept
 Who’s Involved?
 Architect
 Engineer
 Mechanical
 What’s Involved?
 Clash Detection
 3-Dimensional
Modeling
 Coordination of
Mechanical Systems
It is a Linear Process
Our BIM Concept
• BIM is more than just clash
checking and 3D modeling.
• This is a process that’s
maintained throughout the entire
project.
• By doing more of the process,
we establish expertise for each of
the disciplines.
• We can do the work ourselves
or we can coordinate the work
more effectively.

Detailing During Design Using Tekla

Phase I (Mill Order Model)

Phase II (Connected Model)

Phase III (Drawing Extraction)

Precast and Cast-in-Place
Integrated Modeling Services
Steel Detailing During Design Using Tekla Structures
Integrated Modeling Services
Phase I – “Mill Order Model”

Main framing members in
Tekla
 Digital model used directly
by contractors
– Advanced Bill of
Materials (ABM)
– More accurate material
take off for bid
– Reduce overall
schedule
Integrated Modeling Services
Phase I – Design Drawings
Integrated Modeling Services
Phase II – “Connected Model”

Selected connections completely
detailed in Tekla
 Lateral system major details
 Long-span major details
 Others are project-specific

Connection designs in 3D model
 Fabrication starts sooner
 Design intent clear
 Project complexity clear

Owner gets digital 3D model file
 Ready for steel fabricator detailers
to create shop drawings
Integrated Modeling Services
Phase II – Design Drawings
Integrated Modeling Services
Phase III – “Drawing Extraction”
 Drawing Extraction
 Often delegated to fabricator
 Then out-sourced -- Low cost labor
 Thornton Tomasetti can/should
self-perform on select projects

Performing here can speed schedule
on some projects
 Shop drawings complete at Award
 CNC Downloads readily available
 Speeds Shop Drawing Review

Phase III – Drawing Extraction
Integrated Modeling Services
Precast and Concrete Modeling
As Part of Design Projects (Add service or basic fee)
 Partial reinforcement detail of congested areas
 Deliver detailed reinforcing details as design
deliverables
 Required on several current international projects
Stand Alone Service to Contractors
 Design and detail precast
Integrated Modeling Services
Precast and Concrete Modeling





Model different structural elements
Enhances clash detection
Better trade coordination
Full profile element models
See clearances and connections
 Single model: Steel, concrete, wood
 Coordinating for much more
intuitive design
 Becomes basis for RFID control
Integrated Modeling Services
Precast and Concrete Modeling

The use of Tekla-driven Building
Information Modeling (BIM)
allows for enhanced design and
visualization of complex
structural conditions

Model (or components of) can be
delivered to reinforcement subs
that embrace technology

Precast and Concrete Modeling
The Production Model
The BIM Model
The Production Model
 One model design process
 One model to carry through the
detailing
 One location for all of the
information
 One model to maintain and
coordinate
One Model Design Process
 One model is used to house
the geometry as a master
model
 Pieces of this model are
used for analysis
 Analysis results are
incorporated into the master
model
 Trades are coordinated with
exports of the master model
One Location for the Information
 All of the history and the
data about a member is in
the model
 Size, location, end loads,
camber, RFI and anything
about a specific member
is located in the model
 The data is maintained
and expanded throughout
the process
One Model to Maintain and Coordinate
 No more making sure the
models match
 This reduces hours of
review and copy check
time
 Exports from one model
to other trades ensures
that all trades get up to
date information
