The Government of Tamil Nadu created a Special Purpose Vehicle (SPV) scheme for implementing the

Chennai Metro Rail Project. This SPV named as “Chennai Metro Rail

Limited” was incorporated on 03.12.2007 under the Companies

Act.

The Phase I and its Extension of Chennai Metro Rail project covers

a length of 54 kms network and consists of two Corridors with total

of 41 Stations. Started Commissioned in the year 2015 and

completed in 2019.

The Chennai Metro Rail Phase II project is a significant expansion of the city's metro rail network. Once

Phase II is fully operational, the total metro rail network in Chennai will be

173 kilometers.

A total of 23 no’s of Tunnel Boring Machines (TBMs) is expected to be

used in the Phase II of CMRL Project for boring of Twin Tunnels. Which is first in any metros around the world to have 23 Nos. of TBM

simultaneously.

The Phase II of CMRL Project is the first Metro in India to be the Single Largest Metro Rail Project to be

implemented in one stretch

Coimbatore

The Coimbatore Metro, also known as Kovai Metro, is a proposed mass rapid transit system (MRTS) in Coimbatore, Tamil Nadu. It is a significant project that aims to enhance the transportation infrastructure and connectivity of the city.

The first phase of the project will focus on constructing two corridors that will connect major landmarks in the city.

Funding for the Coimbatore Metro has been secured, with the Tamil Nadu government allocating Rs 9,000 crore for the project.

Madurai

Madurai Metro project is a mass rapid transit system (MRTS) proposed to be built in Madurai, Tamil Nadu by Chennai Metro Rail Ltd. (CMRL).

The project’s Detailed Feasibility Report (DFR) was prepared and submitted to the Government.

The feasibility report suggested building a 31 km metro line between Thirumangalam – Othakadai with 20 stations and a train maintenance depot

BIM Implementation – Challenges, Adoption,

& Steps

RAI L SUM MI T 2 02 4

in BIM Implementation

Challenges

Managing construction projects involves major challenges like cost overruns, schedule delays, communication breakdowns,

coordination issues, and resistance to new technologies, which hinder overall efficiency.

Resistance to Adopt BIM – WHY?

• Unsupportive Organizational Culture • No Client Demand • The unwillingness of all stakeholders in BIM adoption • Lack of Clear Benefits

So, Owner / Client plays an important role in the implementation of any technology but at the other side it is the responsibilities of the consultancy / contractors to use the right

tool without hesitation

RAI L SUM MI T 2 02 4

Organization level

Factors in BIM Adoption

1. 3D Software cost

•Around 50% cost higher than the 2D software (ex., AutoCAD Vs Revit) AEC collection Autodesk is covering many software

2. Design / Drawing – (Revisions / Changes)

•Most people will think that modifications will incur more time when we do the changes in the 3D model. It's all about the strategy, how and which tools are being deployed.

3. Manpower availability

•Engineers are moving towards learning and practicing the 3D software so getting the resource is not a problem

4. Transition to new technology

•Some learnings must happen among the Junior / mid-level group in the organization to adopt any new things

5. Mis Guidance

•People unaware of the BIM advantages often misguiding the top-level organization not to adopt any new technologies

“Discuss with a BIM / Technology Expert if you are looking to implement BIM or

any new Technology in your projects”

RAI L SUM MI T 2 02 4

With BIM implementation

Steps to achieve full benefits

BIM Project Manager Deployment

• To guide the process. Without a BIM PM, initiating and formulating the BIM process will lead to incomplete use of BIM.

Organisation BIM Guidelines

Discuss, Formulate the Organization BIM Guidelines and Standards.

Employer Information requirement (EIR).

Employer Information requirement (EIR) i.e., the Contract document to be created to support BIM Implementation

The full benefits of BIM can be harvested only if the implementation stage and processes of BIM comes at the right time. Without

having the proper protocol for BIM Adaptation would leads to failure.

RAI L SUM MI T 2 02 4

in BIM Implementation

Managing hurdles

To Adopt BIM or any technology over the previous one, we need to sell our idea and convince the people at our top management level

In few cases, Straight away go ahead may happen

In other cases which is 95% which can only be convinced with producing the case studies, white papers and meeting with the software provider

In Our Case, We have submitted case studies from other metros and Infra projects adopted BIM

Next Important thing we have done some exercises and shown the results and explained the benefits

Alignment Plan involves balancing safety, managing traffic flow, minimizing environmental impact and social equity

Our First Phase of work starts with the Alignment planning as this is very challenging in a dense city like Chennai.

CMRL routed the alignment even in the narrow roads to cater the needs of city mobility demand.

We have 4 continuous interchange stations with double decker trackway. Both Upline and Downline will operate 4 trains at same time.

We used Infraworks and Civil 3D for the preliminary alignment and station planning

Design in context

Planning Stage

The viaduct bridge and station rail design process is particularly interesting in Infraworks as it has a path to Revit for final design and documentation.

The images highlights the possibilities of land / building acquisition planning developed in context within Infraworks

3D Visualization

 BIM Work starts with a Idea or Hand Sketch to 3D Model Methodology

 At first instance, 3D model shall be used for the visualization purpose. For Design Alternatives on quick turn around

 CMRL used Autodesk software to create the 3D views for concept / Preliminary design of stations and viaducts

Detailed Design Stage

Next step we used the Autodesk Revit software for the creation of detailed design models

Models were developed for various disciplines andused for Iteration of design at various stages

we saved a lot of time while doing the design iterations because we have employed the right 3D tool like Revit

Models were used for the extraction of quantities and cost which was very useful for the construction / Execution Tender

The various discipline design models developed for stations, viaducts and tunnels as follows,

• Structural

• Architectural

• Track

• Plumbing

• Electrical

• Mechanical (Fire Fighting, Fire Alarm & SCADA / BMS)

Different Discipline design models are shown below,

Design – Built Contractors Models

At the stage of construction, the Civil, E&M and various system wide contractors are on board.

All our system wide contracts are Design Build contracts.

Below are the discipline wise contract for one packages, (Which is 10km approx.)

•Civil, Structural, Architectural & Plumbing

•Track

•Electrical & Mechanical

•TVS & VAC

•Telecom

•Tetra

•Power Supply & Overhead Equipment

•Platform Screen Door

•Lifts & Escalator

•Automated Fare Collection

Each station consists of 15Nos. model. We have all our models developed in Autodesk Revit and we collaborated in Autodesk BIM360 as CDE

The important use of various 3D models is the Interface Coordination and Resolution

RAI L SUM MI T 2 02 4

 CMRL working towards creating precise digital replicas

of its infrastructure and assets further extends to

reinforces its dedication to sustainable environmental

development

 CMRL’s main objective of Facility Management is to

achieve optimal management of the asset and, its

content (equipment, spaces, furnishings, etc.).

 The digital twin initiative will bring a paradigm shift in

Chennai Metro Rail operational strategy, enabling

proactive solutions and predictive maintenance to ensure

uninterrupted service quality.

 Driven by a commitment to passenger satisfaction and

operational excellence, the company is poised to extend

this transformative project to all stations, further solidifying

its position as an industry leader.
