National BIM Standard Definition -
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 to
support and reflect the roles of that stakeholder. The BIM is a shared digital
representation founded on open standards for interoperability.
The US National BIM Standard promotes the business requirement that this model be
interoperable based on open standards.

If business processes are changed the following benefits
have been demonstrated:
◦ Better visualization by the Owner
◦ Elimination of conflicts, RFI’s and change orders
◦ Significantly faster project delivery times
◦ Elimination of construction drawings and going straight to
shop drawings
◦ Numerical controls passed directly from the model to
fabrication
◦ Data collected during design & construction used for
operations, sustainment and contingency planning
◦ Information flows when standards exist

Earlier Decisions are Less Expensive…
BIM modeling costs vary based on several factors:
◦ Purpose of modeling effort
◦ Phase of project design
◦ Level of detail of the model
◦ Number of updates to the model
 As rule of thumb BIM modeling will range between .1% to
.5% of the project construction value
 Conservatively BIM can save projects 3% to 5% of the
construction value


 Overall savings in MEPF
coordination of
$184,940 as a result of
shorter meetings and
reduced downtime from
travel
 Avoidance of 450
RFI/COs through model
constructability review
 Average cost of major
change order is $10k
means a ‘cost avoidance’
of approx. $4,500,000

Cost of modeling the Ritz

BIM Project Execution Planning Guide
This BIM Project Execution Planning Guide is a product of
the BIM Project Execution Planning buildingSMART
alliance™ (bSa) Project.
The bSa is charged with developing the National Building
Information Modeling Standard™ (NBIMS).
This guide was developed to provide a practical manual that
can be used by project teams for designing their BIM
strategy and developing a BIM Project Execution Plan.
The core modeling and information exchange concepts are
developed to complement the long term goals of the bSa in
the development of a standard that can be implemented
throughout the AECOO Industry to improve the efficiency
and effectiveness of BIM implementation on projects.
The Model Progression Specification
Identification of the BIM author (also referred to as the Model Component
Author). It should be noted that in the early phases of a project, BIM objects may
be created by one party at a lower LOD as a placeholder, and at later phases,
then may be replaced by a higher LOD object created by the party responsible
for the actual design.
A description of the file formats used by the modelers to deliver the BIM, as well
as the software applications and their version number used to create the BIM.
A description of the appropriate uses (and decisions) that can be made based
on the project phase and LOD of the BIM.
A description of what LOD a particular BIM object is required to use for a
particular phase of the project.
A description of the Level of Detail (LOD) for model objects based on UniFormat
assemblies. There are five defined levels of detail for BIM models (defined as
100, 200, 300, 400, and 500).

provide accurate visualization of
the design intent, but we have
accurate information of every
architectural element as well as
structural & MEPF elements

 Coordination meetings now
taking place via GoToMeeting
sessions and Navisworks
 Subtrades work from their offices
 Meetings are shorter 1½ to 2
hours vs. 4 to 5 hours in the
traditional 2D process
 PDF digital signatures of
coordinated drawings
 Overall savings of $184,940 as a
result of shorter meetings and
reduced downtime from travel


The Swinerton contracted Vico Services to
deliver Virtual Construction™ Services for
the ‘719 Ash’ Hotel & Residences project
located in San Diego, CA.

The proposed building contains three
stories of mixed use
office/retail/restaurant space, 16 stories of
guest suites and condominiums, and three
stories of underground parking. The
structure is primarily cast-in-place
reinforced concrete with structural steel
supporting the penthouse roof. The
exterior finish contains panel and plaster
systems, glazed curtain wall and aluminum
window systems.

This scope of Virtual Construction services
on this project is limited to architectural
and structural building systems only.
Interior construction and finishes are
limited to framed walls and ceiling
elements, interior doors, and stairs. The
project was divided into three phases for
delivery.
◦ Phase 1: 3D Model, Constructability
Analysis, Rendered Images
◦ Phase 2: Knowledge Database, Modelbased Quantity Report and Estimate
◦ Phase 3: Schedule Optimization and 4D
Construction Simulation

What are our BIM standards?
Who maintains the standards?
Who hosts the BIM model?
Are the Facility standards loaded into the BIM
platform?
Is our BIM solution integrated into the
Institution’s Enterprise system? Should it be?
Is our culture capable of greater collaboration,
teamwork and sharing of information?
