Course Description
• BIM is an intelligent 3D model–based process that provides insight for creating and
managing building projects faster, more economically, and with less environmental impact.
The success of BIM for building delivery is fueling the push towards using BIM for model-
based lifecycle management. To capitalize on the value of BIM, building owners are now
starting to reuse the building models and information created during design and
construction to streamline their building management and operations.
• The ‘i’ in BIM—information—is the key to BIM’s potential for lifecycle management. The
ability of owners to realize that potential hinges on the use of standardized data streams
throughout design, construction, and commissioning, as well as thorough understanding
of the end use, and users, of that building data. In response, owners are starting to
mandate the use of BIM during design and construction, and to specify digital deliverables,
in anticipation of reusing building models and data for their operations.
• The ability to integrate as-built building models with operations-based building systems
results in model-based handover deliverables that help owners minimize their startup time,
lower their operating costs, better manage their assets, and reduce their energy use.
Learning Objectives
At the end of this program, participants will be able to:
1) Attendees will be able to justify mandates for the use of BIM during design
and construction.
2) Attendees will able to support their requests for digital deliverables in
anticipation of reusing building models and data for future operations.
3) Attendees will be able to integrate as-built building models with operations-
based building systems.
4) Attendees will be able to minimize start-up time, lower operating costs, better
manage assets, and reduce energy use.

Workflow
Wikipedia Building Information Modeling (BIM) aims to build a
collaborative relation between designers and
constructors, so how is that different from LC?
BIM is technology. It doesn't aim, it does make possible
different conversations because it is a great tool for spatial
representation of design. LC structures those conversations
and connecting design, logistics and installation. LC designs
and activates the network of commitments necessary to
deliver the project. It is necessary to enable Lean
Construction ideals but not sufficient.

• “Modeling leads to lean construction, which is green construction,” Kahl says. His company
designed the new University of Southern California School of Cinematic Arts, a $165-million, 137,000-
sq-ft historic California-style complex built to LEED silver standards. The goal was to design a building
that would last for the next 100 years.
• He estimates that the enhanced energy studies allow for buildings to be designed to perform up
to 20% more efficiently.
• BIM also reduced the amount of waste because it allowed estimates to be more precise with no
revisionist work, no tearing out pieces for reinstalling and no overstock, Kahl says.
• “Without modeling, we wouldn’t have been able to install as efficiently,” he adds. He also credits BIM for
allowing greater use of prefabrication, which resulted in less waste and time spent in construction
onsite.
• Because models are shared in real time, the team could make decisions faster, contributing to a project
that was delivered three months ahead of schedule and under budget, Kahl says.
Raymond Kahl, principal in
charge at Atlanta-based Urban
Design Group, says BIM allows a
project team to take a holistic
approach to design and
construction.

c. Organized and properly filed in an equivalent Document Control
System for archive and reference.
The Unified Facilities Guide Specifications
(UFGS) …a joint effort of several US federal government agencies, are construction guide
specifications used in facility construction projects of the participating agencies… the
types of information required in operations & maintenance data package:
• Spatial Assets
• Equipment Assets
• Parts and Warranty Contacts
• Warranty Information
• Replacement Parts
• Operating Plans
• Preventive Maintenance
• Emergency Operations
• Troubleshooting

• Safety Instructions
• Coordinates
• Products and Equipment

Construction Operations Building
Information Exchange (COBie)
The COBie approach is to enter
the data as it is created during
design, construction, and
commissioning, … Designers
provide floor, space, and
equipment layouts. Contractors
provide make, model, and serial
numbers of installed
equipment. Much of the data
provided by contractors comes
directly from product
manufacturers who can also
participate in COBie.

Emerging Trends Quantifying The Model
Emerging Trends Enhanced Delivery Methods - AIA E202 – BIM Protocol Exhibit
LOD 100 Essentially the
equivalent of
conceptual design,
the model would
consist of overall
building massing and
the downstream users
are authorized to
perform whole
building types of
analysis (volume,
building orientation,
cost per square foot,
etc.)
LOD 200 Similar to schematic
design or design
development, the
model would consist of
"generalized systems
or assemblies with
approximate quantities,
size, shape, location
and orientation."
Authorized uses would
include "analysis of
selected systems by
application of
generalized
performance criteria."
LOD 300 Model elements are
suitable for the
generation of
traditional construction
documents and shop
drawings. As such,
analysis and
simulation is
authorized for detailed
elements and
systems.
LOD 400 This level of
development is
considered to be
suitable for fabrication
and assembly. The
Model Element
Author for this LOD is
most likely to be the
trade contractor or
fabricator as it is
usually outside the
scope of the
architect's or
engineer's services or
would constitute
severe risk exposure
if such parties are not
adequately insured.
LOD 500 The final level of
development
represents the project
as it has been
constructed - the as-
built conditions. The
model is suitable for
maintenance and
operations of the
facility.
The requirements for
a LOD500 model
should be driven by
Lifecycle Applications,
and could actually
have less detail than
a LOD 400 model.

Measuring the Impact of Rework on
Construction Cost Performance
• Bon-Gang Hwang1; Stephen R. Thomas, M.ASCE2; Carl T. Haas, M.ASCE3;
and
• Carlos H. Caldas, M.ASCE4
• Abstract: Rework continues to affect both cost and schedule performance
throughout the construction industry. The direct costs alone often tally to
5% of the total construction costs. Using the data obtained from 359
construction projects in the Construction Industry Institute database, this
paper assesses the impacts of rework on construction cost performance
for projects in various categories
