In our organization, there are different departments like Architecture, Construction,
Electrical, Mechanical, Quality Control, Shop Drawing etc.
ARCHITECTURE
Architectural drafters translate ideas into technical drawings, detailed plans, and
models for construction of residential and commercial buildings, working with data
outlined by architects and engineers.
Architects can outsource time consuming drafting work to reliable CAD designers,
who understand architectural design and construction values to deliver accurate building
designs of complex projects.
With extensive experience working with AutoCAD and Revit, our team of
architectural drafters turns drawings, plans, blueprints and PDF files into the local organize
with clean layers and references. Our trained team members partner with architects to
provide architectural CAD drafting and detail engineering services from concept to
completion
STRUCTURE
It can load various components, such as roofs, slabs, furniture, lighting, and doors.
Typically, a person working on a building project will craft a custom 3D Revit structure for
their project. This scale model will show everything from elevations to rebar types. They
can use this model to view their drafts in a 3D environment and adjust as needed. The
models also allow for cutaways and floor plans of a building, so designers can more easily
explain their projects to outside viewers. The extremely detailed, precise models you can
make in Revit are a valuable part of the design process.

Introduction of Project
 Point cloud – Scan to BIM
Table 3.5-2 : Process chart of point cloud (scan to BIM)

Point Cloud to BIM is a 3D model created with laser scanning. Point cloud modeling
is widely popular for its precision. As you can extract detailed elements of an object
captured in physical space.

This enables accurate modeling, clash coordination, and quantity take-off (QTO) or
Bill of materials (BOQ). Several construction projects in the renovation and the
extension stages are using point cloud scan to BIM process for 3d model creation,
3d visualization, animation and quality inspection.

Scan to BIM modeling involves the technique of making a digital representation of
an existing building condition with its functional and physical attributes.

Laser scanners facilitate in obtaining a perfect 3d scan to BIM, which is then
imported into the 3D BIM software. Faro scan to BIM process is designed by
architects, engineers, and general contractors to process 3D laser scan data quickly
and accurately.

Revit scan to BIM is also popular for creating as-built models for refurbishment and
renovation. Scan to BIM Revit facilitates creation of as-built BIM model for
renovation work of infrastructure assets including tunnels and bridges.

In the AEC sector, laser scan to BIM best practices is used by the surveyors, owners,
architects, engineers, and general contractors for their renovation and refurbishment
projects.

4.1 STUDY OF CURRENT SYSTEM
In The Current System, a one BIM Modeller uses various software such as Autodesk
Revit, AutoCAD, Navis Works, and Autodesk Scan to BIM, PDF Editor.
4.2 PROBLEM AND WEAKNESSES OF CURRENT SYSTEM

One of the most common challenges that BIM Managers face is that BIM data
comes from multiple sources (different design disciplines, different software,
different companies…), all of which present the data in a different way. In addition,
the large volume, velocity and variety of BIM data makes it hard to manage

BIM is a digital process that requires an investment in software and computer
resources. It needs to be seen as a long-term investment for the business, with
returns increasing over a period of time, rather than expecting sizable cost savings
and benefits on the first project
4.3 REQUIREMENTS OF NEW SYSTEM
BIM not only allows design and construction teams to work more efficiently, but it
allows them to capture the data they create during the process to benefit operations and
maintenance activities. This is why BIM mandates are increasing across the globe.

5. SYSTEM DESIGN
5.1 SYSTEM DESIGN AND METHODOLOGY
Systems design is the process of defining elements of a system like system services,
components, workspace, and its template for a system based on the specified requirements.
It is the process of defining, developing, and designing a project which satisfies the specific
needs and requirements of a business or company
Design methods:
1) Evaluation/Assessment: Publish the implementation plan and intent for Building
Information Modeling in your organization as part of an internal assessment
procedure. The following steps are some of the best practices which would help you
in the initial phase of BIM implementation.
•
BIM Ready Evaluation – Evaluate your teams capability in terms of technology and
processes
•
Feedback – conduct feedback sessions on with internal team about adopting
technology, processes and workflows
•
Due Diligence – Evaluate the legal contracts and deliverables expected from each
party
•
Management takes – Ensure that the higher management fully supports the decision
to adopt BIM in the organization.
2) Preparation for the Transition / Project Pre-Planning: Project pre-planning is
paramount for successful transition to BIM. A Standardization in technology
process and trained people is critical for success of technology implementation.
•
Standardization: Make provisions for uniform standards for software
implementation ensure to lay down a process flow for information exchange,
archiving and updating data on a real-time basis so that no crucial
information is lost
Gujarat Technological University

System Design
•
Training: Internal Team has to be equipped with the new software so plan
for numerous Training and Development sessions to increase their expertise
in using BIM.
3) Execution of Plan/Design and Construction: The execution of the plan must be
decided collaboratively in accordance with every stakeholder in the project. This
phase defines the social interactions of the project team throughout the BIM
construction life cycle. A BIM execution plan includes:
•
Portfolio management
•
Test case-based planning and implementation
•
Spatial planning
•
Team restructuring
•
Information handover
•
Defining new roles and responsibilities
•
Measuring performance
4) Operations and Maintenance: The high-level digital model built in the design phase
can be taken as a base for operations and maintenance phase as well. The best
practice is to use building data from this model and rework on it, to incorporate
operations and maintenance for the facility.

tasks involved:
 Model Creation: Using Revit, the BIM Modeller should create a 3D model of the
plumbing system, which involves creating and placing pipes, fittings, fixtures,
valves, and other components.
 Coordination: The BIM Modeller should coordinate with other design disciplines
such as mechanical, electrical, and structural to ensure that all systems are
properly coordinated and integrated into the building's design. This coordination
can be done using Navisworks, which is a software application that allows for
clash detection and resolution.
 System Design: The BIM Modeller should follow the design intent of the project
specifications and create plumbing systems that are efficient and meet all
necessary codes and standards.
 Updating and Revising Models: The BIM Modeller should continuously update
the models and documentation throughout the construction process to reflect any
changes or modifications made during the project.
 Preparation of Drawings: The BIM Modeller should generate 2D drawings from
the 3D model, including plumbing plans, sections, and details. These drawings are
essential for construction and installation of the plumbing system.
 Material Take-offs: The BIM Modeller should prepare accurate material take-offs
from the model to ensure that the correct amount of materials is ordered and used
during construction.
 Documentation: The BIM Modeller should create documentation such as user
manuals, maintenance schedules, and other relevant documents for the completed
plumbing system.
 Testing and Commissioning: The BIM Modeller should assist with the testing and
commissioning of the plumbing system, including verification that the system is
operating correctly, and that it meets the specified performance criteria.
 As-built Documentation: The BIM Modeller should review and finalize the asbuilt models and documentation for handover to the client, including all relevant
information about the plumbing system installed.

The role of a BIM Modeller in a project related to HVAC (Heating, Ventilation, and Air
Conditioning) involves creating and managing digital models of HVAC systems using
Building Information Modeling (BIM) software.
 Review project specifications, design drawings, and client requirements related to
the HVAC system.
 Collaborate with other project team members (such as HVAC engineers and
designers) to identify the scope of work and determine the project timeline.
 Create 3D models of the HVAC system using BIM software such as Revit,
AutoCAD MEP, or Navisworks. The model should include equipment, ductwork,
piping, and other components of the HVAC system.
 Ensure that the model meets the design standards, codes, and regulations of the
project location.
 Coordinate with other trades such as electrical, plumbing, and structural to ensure
that all systems are properly integrated and coordinated.
 Prepare detailed drawings and schedules of the HVAC system components for
fabrication and installation, including ductwork and piping layouts, equipment
schedules, and material take-offs.
 Generate reports for clash detection, interference, and coordination with other
trades. Resolve conflicts and discrepancies with other trades using BIM software
tools and methods.
 Continuously update the model throughout the construction process to reflect any
changes or modifications made to the HVAC system design.
 Assist with commissioning and testing of the HVAC system as needed, ensuring
that the system operates according to design specifications.
 Prepare documentation (such as user manuals and maintenance schedules) for the
completed HVAC system and assist with the handover to the client.
The BIM Modeller plays a crucial role in ensuring that the HVAC system is
properly designed, integrated, and coordinated with other trades using BIM software tools
and methods. The BIM Modeller also provides valuable input to the project team, assists
with problem-solving, and ensures that the project is completed on time and within

 The Firefighting system is a critical component of building design, and is
responsible for protecting the occupants, building, and its contents from fire. The
BIM Modeller uses specialized software such as Revit or AutoCAD MEP to create
3D models of the Firefighting system components, including fire pumps, sprinklers,
fire hydrants, fire alarm systems, and other safety equipment.
 The BIM Modeller is responsible for coordinating the Firefighting system design
with the other building systems, such as the HVAC, plumbing, and electrical
systems, to ensure proper integration and coordination of the Firefighting system
within the building design. This involves collaboration with other design disciplines
and stakeholders such as the Fire Protection Engineer, Contractor, and Client to
resolve design issues, clashes, and coordinate project schedules.
 The BIM Modeler’s role in the Firefighting project includes generating 2D drawings
from the 3D models, including plans, elevations, sections, and details, to be used
for construction documentation. They also create detailed firefighting system
schedules, such as equipment schedules and material takeoffs, to be used for
procurement and installation. The BIM Modeller conducts clash detection between
the Firefighting system and other building systems, and resolves any coordination
conflicts with other trades.
 The BIM Modeller prepares documentation, such as user manuals, maintenance
schedules, and commissioning and testing reports for the completed Firefighting
system. This documentation is critical for ensuring that the Firefighting system is
properly installed, tested, and maintained throughout the life of the building. The
BIM Modeller also continuously updates the Firefighting system models and
documentation throughout the construction process to reflect any changes or
modifications.
 They work closely with the Fire Protection Engineer to ensure that the system is
designed to meet the appropriate codes and standards. They also ensure that the
Firefighting system is properly coordinated with the building's emergency
evacuation plan.

7.1 TESTING STRATEGY
The BIM Modeller checks Revit models and assists with verifying compliance to BIM
Requirements. The add-in is designed to quickly identify possible conflicts or areas of noncompliance in a model by running several standards checks which can be viewed or
exported for analytical review.
The purpose of a testing of project is to prescribe the scope, approach, and resources
required to carry out the testing activities. It also includes the scheduling of testing
activities.
Testing Strategies Consists of the following steps:

Unit Testing: This involves testing individual components or modules of the BIM
project to ensure they are working as intended. Unit testing helps to catch bugs early
in the development process.

Integration Testing: This involves testing how different components of the BIM
project work together. Integration testing helps to identify any issues that may arise
when different parts of the project are combined.

System Testing: This involves testing the entire BIM project as a whole. System
testing helps to ensure that the project meets all the required specifications and
performs as expected.

User Acceptance Testing: This involves testing the BIM project with end-users to
ensure that it meets their needs and is easy to use. This testing is typically done
towards the end of the development process.

Performance Testing: This involves testing the BIM project to ensure that it can
handle the expected load and performance requirements. This testing helps to ensure
that the project can handle the demands placed on it in real-world use.

Testing
Security Testing: This involves testing the BIM project to ensure that it is secure
and cannot be easily hacked or compromised. This testing helps to protect sensitive
data and ensure that the project meets security standards.
A comprehensive testing strategy for a BIM project should involve a combination of these
different testing approaches to ensure that the project is high-quality and meets all the
required specifications.
7.2 TEST RESULTS AND ANALYSIS
BIM Modeller can use a variety of tools and techniques to test their MEP (Mechanical,
Electrical, and Plumbing) projects with clash detection.

Create a 3D model of the MEP systems: The BIM Modeller creates a 3D model of
the MEP systems using BIM software such as Revit, AutoCAD MEP, or
Navisworks.

Import the models into clash detection software: The BIM Modeller imports the 3D
models of the MEP systems into a clash detection software such as Navisworks. The
clash detection software highlights any potential clashes or conflicts between the
different systems in the model.

Review the clash results: The BIM Modeller reviews the clash results and identifies
the clashes that need to be resolved. They may use different filters and grouping
techniques to organize the clashes and make it easier to identify the root cause of
the clash.

Resolve the clashes: Once the clashes are identified, the BIM Modeller resolves
them by adjusting the positions of the conflicting components, changing the routing
of the systems, or adjusting the sizes of the components.

Re-run the clash detection: After resolving the clashes, the BIM Modeller re-runs
the clash detection software to ensure that all the clashes have been resolved and
there are no new clashes introduced.

Document the clashes: The BIM Modeller documents the clashes and their
resolutions in a clash report. The clash report is shared with the project team,
including the designers, engineers, and contractors, to ensure that everyone is aware
of the clashes and their resolutions.

8.3 PROBLEMS ENCOUNTERED AND POSSIBLE SOLUTIONS
In the project of Firefighting, client demand was to use Victaulic software base Revit family
which we needed in the mechanical room, and it was not available on the internet so to
tackle that phase, I simply made the families of equipment of mechanical room same as the
design data of Victaulic equipment given by designer and then we used in our project.
