7. Objective of BIM Project Execution
Plan
To successfully implement Building Information Modelling
(BIM) on a project, the project team has to develop a
MBIM Project Execution Plan.
The BIM Project Execution Plan defines uses for BIM on
the building construction project from design,
engineering, construction to facility management, along
with a collaboration process for executing BIM on the
project.
The goal of the BIM Project Execution Plan is to manage
and control the quality of the BIM deliverables

9. Quality for BIM ProjectQuality for BIM Project
Q lit ti t ’ ( d) i t f lQuality means meeting customers’ (agreed) requirements, formal
and informal, at lowest cost, first time every time.
To success, we should understand the current and future customer
d h ld d dneeds, should meet customer requirements and strive to exceed
customer expectations.
We should create and maintain an internal environment in which
people can become fully involved in achieving the project’s
objectives. A desired result is achieved more efficiently when
activities and related resources are managed as a process.
So identifying, understanding and managing interrelated processes
as a system are required. Further continual improvement of the
overall performance should be a permanent objective of the
organization.

34. Model StructureModel Structure
The success of a BIM enabled project delivery process is highly dependent upon the level atThe success of a BIM enabled project delivery process is highly dependent upon the level at
which the entire project team can communicate and work collaboratively for the duration of
the project.
For buildings with a large footprint or multiple floors, the project team may split the model into
l ( fl ) ith th di t dseveral zones (or floors) with the corresponding trades
All trades will be modeled at the correct elevation
All elements of the building must be represented in only one file and should be modeled by
their specific trade. (For example, the architectural model provided for 3D Coordinationp ( p , p
should not include any of the structural elements contained in the structural model. Lights should
be modeled by the electrical engineer, not the architect)
All 3D model files must strip extraneous 2D and/or 3D elements from the model before
submission for clash detectionsubmission for clash detection
The architectural ceilings should contain information of lights, diffuser, speaker, CCTV, etc. as
required by design. (For example, lights are to be centered on a grid with proper spacing)
All models should include separate 3D representations of required clearances and/or access
i f i li h l h d bl Threquirements for equipment access, light clearances, overhead cable tray access, etc. These
clearance/access models should be in a separate layer(s)/level(s) per each trade and labeled
as such

LOD 100 The model equivalent of conceptual design the model would consist of overallLOD 100 – The model 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 – Model that includes basic elements including windows walls and doors. This level of
d li i f i li ti d b i l i d i i il t th h ti d imodeling is for visualization and basic energy analysis and is similar to the schematic design
or design development. It consists of generalized systems or assemblies with approximate
quantities, size, shape, location, and orientation.
LOD 300 – Model elements are suitable for construction and are the equivalent of traditional
t ti d t d h d i Thi d l l l ld b it bl f l i dconstruction documents and shop drawings. This model level would be suitable for analysis and
simulation of detailed elements and systems.
LOD 400 – Model level of development considered suitable for fabrication and assembly. This
model will include all as-constructed details for the CLIENT’s use to manage the facility. This is
h i l f b il d i i h di i l ithe equivalent of as-built drawings in the traditional construction process.
LOD 500 – The final level of detail represents the project as it has been constructed including
property assets itemized with key parameters required by the CLIENT added to the model. All
as-built record drawings and documentation at the time of turnover must be provided in the
CAD f l f El l d d h d l b d l d b h h 2D d 3DCAD native file format. Elements included in the model must be detailed in both the 2D and 3D
documentation for CLIENT use. Elements must be clearly marked or tagged and visual in both
the 2D and 3D documentation.

El i C i i dElectronic Communication procedures
Communication protocol should be established between all
project team members to ensure smooth collaborationproject team members to ensure smooth collaboration.
Electronic communication between stakeholders can be
created, uploaded, sent out and archived through the, p , g
project management system.
Copies of all the project related communication should be
d f f k d f fsaved for safekeeping and future reference.
Document management (file folder structure, permissions and
access folder maintenance folder notifications file namingaccess, folder maintenance, folder notifications, file naming
convention, etc.) should also be resolved and set up at the
earliest possible time.

A l k f F l T f P l (FTP)An electronic workspace of File Transfer Protocol (FTP) or
Asset Lifecycle Management system (ALM) will be
established for the purpose of efficient and timely transferestablished for the purpose of efficient and timely transfer
of model and database files.
This workspace will provide a collaborative location where
the current contract BIM files, coordination files, and fully
coordinated submittal files will reside.
h M d b d bEach BIM coordination team member stores and obtains
data from this location. Project team members are to upload
updated copies of their files, provide notification, and toupdated copies of their files, provide notification, and to
make collaboration comments and annotations as often as
necessary to maintain project schedule.

Exchange (COBie) is a data format for the
publication of a subset of building model
information focused on delivering building
information not geometric modeling. It is closely
associated with building information modeling (BIM)
approaches to design, construction and
management of built assets.g

78. Quality ManagementQuality Management
I d t d l lit i j t h t lIn order to assure model quality in every project phase, control
procedures need to be set in place.
Each of the models created during project progression and
d l d b l d d d ldevelopment needs to be pre-planned considering model content,
level of detail, format and responsible party for updates, quality
and distribution of the model to all the parties involved in the
di ti ff tcoordination efforts.
Each of the parties contributing to the BIM model should have a
responsible person or Model Manager to handle the model.
Model Managers, as part of the core BIM team, are in charge of
participating in design reviews and coordination sessions along with
taking care of all the issues that might arise with keeping the model
updated, accurate and comprehensive.

79. Quality Control ChecksQuality Control Checks
CHECKS DEFINITION
Vi l h k
Ensure there are no unintended model components and the
Visual check
Ensure there are no unintended model components and the
design intent has been followed
Interference
check
Detect problems in the model where two building
components are clashing including soft and hardcheck components are clashing including soft and hard
Section check
Cut section to compare with the 2D drawing and take
measurement for critical areas
Standard check
Ensure that the BIM and AEC Standard have been followed
(fonts, dimensions, line styles, levels/layers, color, etc)
Model integrity
check
Describe the QC validation process used to ensure that the
Project Facility Data set has no undefined, incorrectly defined
or duplicated elements and the reporting process on non-
compliant elements and corrective action plans
Random check
Checking any missing, un-reasonable and clash matter thro’
the model
