Project 1
1A. To select the right corridor for Bangaluru Metro, different options were tried. The two main options tried were
- Purple line – Bayyappanalli-Mysore Road
- Green line – Nagasandra-yelachinnahalli
- Bangaluru has 5 major routes including oprating & under construction.
- Based on the expected ridership of the corridor.Bayyappanahalli-Mysore road was selected.
- For this corridor extension was also tried, MG road to Yeshwantpur. Impact of this is marginal on the ridership, hence this extension is not considered and the corridor Bayyappanalli to Mysore Road is selected as the best option.
- After carrying out detailed feasibility study for this corridor, it was found that this line connects the major part of the city with the east corridor of the city which covers 18.22 kms elevated route.
- Elevated route reduces the traffic in the city & working professionals can easily commute to their work location easily on time.
1B. Bangalore Metro has two operational lines: the Purple Line and the Green Line. They intersect at Majestic Station which is also known as Krantivira Sangolli Rayanna Railway Station. This station allows passengers to switch between the two lines and also access the city railway station.
The Bangalore Metro Phase 2 project will add two more lines: the Yellow Line and the Pink Line. They will intersect with the existing lines at different locations. The Yellow Line will intersect with the Green Line at Rashtreeya Vidyalaya Road Station and with the Purple Line at Jayadeva Hospital Station 3. The Pink Line will intersect with the Green Line at Majestic Station and with the Purple Line at MG Road Station.
The intersection locations are chosen to provide better connectivity and convenience for the metro users. They also help to reduce congestion and travel time on the roads.
1C. Bangalore Metro Phase 2 project has four new depots planned for different lines and extensions. They are:
- Hebbagodi Depot for the Yellow Line (RV Road – Bommasandra)
- Kothanur Depot for the Pink Line (Kalena Agaraha – Nagawara)
- Kadugodi Depot for the Purple Line extension (KR Puram – Whitefield)
- Challagatta Depot for the Purple Line extension (Mysore Road – Challaghatta)
The depots are essential for the maintenance and stabling of the metro trains. The reasons for choosing these locations may vary depending on factors such as availability of land, connectivity, cost, environmental impact, etc.
1D. Bangaluru Metro has some sections that are built underground using tunnel boring machines (TBMs). The operational underground sections are:
- Purple Line between Cubbon Park and City Railway Station (4.8 km)
- Green Line between Sampige Road and National College (4.0 km)
The requirement of tunnel route may depend on various factors such as:
- Land acquisition issues for building elevated or at-grade sections in densely populated or congested areas
- Preservation of heritage structures or aesthetic appeal of the cityscape that may be affected by elevated or at-grade sections
- Geotechnical conditions of the soil and rock that may influence the feasibility and cost of tunneling
- Traffic management and safety issues that may arise during construction of elevated or at-grade sections
the total length of Bangalore Metro tunnel sections is:
- Operational: 8.8 km (4.8 km on Purple Line and 4.0 km on Green Line)
- Under-construction : 13.885 km on Pink Line 1
The total length of Bangalore Metro tunnel sections will be 22.685 km when the Pink Line is completed.
1E. The total length and number of stations of Bangalore Metro are:
- Operational: 69.9 km and 64 stations (55 elevated, 8 underground and 1 at-grade)
- Under-construction: 103.3 km and 72 stations (Phase 2, 2A and 2B)
The total length and number of stations of Bangalore Metro will be 173.2 km and 136 stations when the under-construction phases are completed.

High level scope of design consultants for station construction
Construction Of Stations
It is proposed to construct the elevated stations with elevated concourse over the road at most of the locations to minimize land acquisition. To keep the rail level low, it is proposed not to take viaduct through the stations. Thus a separate structural configuration is required (although this may necessitate the break in the launching operations at each station locations)
Sub-structure for the station portion will also be similar to that of viaduct and will be carried out in the same manner. However, there will be single viaduct column in the station area which will be located on the median and supporting the concourse girders by a cantilever arm so as to eliminate the columns on right of way.
Super-structure will consist of 3 pre-cat U Girders for supporting the track structure and I Girder / Double T Girders for supporting the platform and concourse areas. A pre-cast or cast in-situ pre-stressed cross girder will be required over the middle piers for supporting platform structure. Box shaped in[1]situ pre-stressed cantilever cross girders are planned for supporting the concourse girders and escalators at mezzanine level. All the members will be pre-cast in a construction depot and launched at site through cranes.
Grade of Concrete
It is proposed to carry out construction work with design mix concrete through computerized automatic Batching Plants with following grade of concrete for various members as per design requirement/durability considerations.
- Pile cap and open foundation - M -30
- Piers - M –40/M-50
- All pre-cast element for viaduct and station - M -45
- Cantilever piers and portals - M -45 - M -60
- Other miscellaneous structure - M - 30
For all the main structures, permeability test on concrete sample is recommended to ensure impermeable concrete.
Reinforcement and pre-stressed Steel
It is proposed to use HYSD 415 or TMT steel as reinforcement bars. For pre-stressing work, low relaxation high tensile steel strands with the configuration 12 T 13 and or 19 K 15 is recommended (confirming to IS:14268).
Road width required during Construction
As most of the construction is to be carried out on the middle of the road, central two lanes including median will be required for construction activities. During piling and open foundation work, a width of about 8m will be required for construction and the same will be barricaded. It is proposed that two lanes are provided for traffic on either side during construction by widening of roads, if necessary. In certain cases, one way traffic may be resorted to. All these actions will require a minimum period of about 4 to 6 months. During this period, the State Government can go ahead with the following preliminary works:
- Preliminary action for diversion of utility and preparation of estimates thereof.
- Reservation of land along the corridor, identification and survey for acquisition.
Once the Corporation is formed, the Corporation has to take action for appointment of consultant for Project Management and proof checking including preparation of tender documents. Simultaneously, action is also to be taken for detailed design for structures for elevated corridors.
Soil Characteristics & Field Investigation
Field Investigations
- Four boring rigs with all requisite equipments and accessories were mobilized at the work site. A team of technical personnel with skilled labors were also deputed.
- Fifty-one boreholes of 150mm diameters were bored to a maximum depth of 45.0 meters below the existing ground level. The boreholes were made as per IS: 1892-1979.
- Disturbed samples were collected at every change of strata or about 1.5 metres depth interval whichever was earlier. The samples so collected were carefully sealed and numbered with full particulars for identification and sent to the laboratory for conducting the required tests.
- Standard Penetration Tests were conducted in the boreholes at regular intervals of 1.5m as per IS: 2131-1981. In this test, the standard split spoon sampler is driven into the ground at the required depth by means of standard hammer of 63.5 Kgs weight, falling from a height of 75cm. Number of blows for the first 15cm is not taken into consideration because of possible disturbances or presence of settled, suspended matters at the bottom of the bore- holes. The total number of blows for the next 30cm depth of penetration is considered as SPT ‘N’ values
Laboratory Investigation
The following laboratory tests were conducted on the selected samples recovered from the test bore-holes:
(a) Particle size analysis:
- Sieve analysis
- Hydrometer analysis
(b) Particle size
(i) Liquid limit
(ii) Plastic limit
(c) Dry & wet density
(d) Water content
(e) Specific gravity
(f) Direct shear test
(g) Tri-axial test
All the above laboratory tests were carried out as per relevant Indian Standard.
All the samples were identified and classified as per IS: 1498-197
General Geology and Related Characteristics
(a) Location: The Geo technical site investigation carried out from Bayyappannalli to Mysore Road, via Alsoor, MG Road.
(b) Physiography and Climate: Bangalore has a tropical savanna climate (Köppen climate classification Aw) with distinct wet and dry seasons. Due to its high elevation, Bangalore usually enjoys a more moderate climate throughout the year, although occasional heat waves can make summer somewhat uncomfortable. The city has an average annual rainfall of 1670mm.
(c) General Geology: Because it lies in the seismically stable region, Zone III (encompassing parts of Karnataka, Maharashtra, Kerala, Tamil Nadu and Andhra Pradesh), Bangalore has been untouched by major seismic events. Only mild tremors have been recorded frequently in the city. The largest earthquake that has ever hit the city was of magnitude 6.4 in April 1843.
Field Investigations
(d) The present proposal is for the implementation of Phase 2A Metro Line on the ORR and will be an elevated standard gauge corridor with double line section for a route length of 17.130 km (line length of 19.75 km) up to the depot. The corridor proposed is from terminal station at CSB to terminal station at KR Puram and further up to Baiyappanahalli Depot, the other stations being HSR Layout, Agara Lake,Ibbalur, Bellandur, Kadubeesanahalli, Kodibeesanahalli, Marathahalli, ISRO, Doddenakundi, DRDO Sports Complex and Saraswathi Nagar.

Design Phase
The Design Phase consists of four sub-phases:
- Programming Phase
- Schematic design Phase
- Design Development Phase
- Construction Document Phase
Programming Phase
The Programming phase is concerned with following
- Estimating realistic project cost
- Determining the building and user requirements
- Establishing a total building area
- Refining the scope of work
Programming involves gathering information from the intended building occupants and user groups through group and individual interviews. The programming researches current and projected needs in such areas as information and instructional technology, acamedic teaching methods, privacy & security. This results in a comprehensive description of the necessary components of the construction project.
This is the time to determine the effect on existing facilities of projects- in planning and the need for corollary projects such as parking lots or new utility services. State of Michigan building requirements or restrictions, all life safety, fire, environmental and barrier-free code issued are identified.
The project program, the end results of the Programming phase, describes how the finished project will “work”, how will function for the building occupants and how it will meet all the project requirements.
Schematic Design Phase
The schematic Design Phase is concerned with;
- Building systems (structural, mechanical, HAVC, plumbing, electrical)
- Interior & Exterior finishes
- Building site
The purpose of schematic design is to translate the project program into physical drawings of space in the Schematic Design Phase, the project team determine the areas, physical requirements and relationships of the required building spaces and components, confirm or revises the building square footage, the total project budget and the project schedule and occupancy dates.
It provides control strategy for all equipment and system relating to building services such as security and firearms, and defines the technical requirement of phones, data cable, and audio/visual needs.
The schematic drawings- floor plans, site plans, and building elevations are involved and refined for functionality, usually, required adjacencies, code compliance, security, safety, and aesthetics. The project program schematic drawings are scrutinized for possible errors or omissions. The plans are shared and discussed with staff in other areas of the University such as maintenance services, custodial services, logistics, information technology and public safety, to identify possible problems and to coordinate with the needs and practices in these areas.
Design Development Phase
The Design development Phase is concerned with the following:
- Interior & Exterior building materials and finishing
- Furniture & equipment selection and layout
- Cabinetry & custom fabrications
- Lighting & technology designs
- Mechanical, electrical and plumbing systems
In the design development phase, the schematic plans and elevations are reviewed, revised and expanded to incorporate all the details and specifications required for construction. Project components are locked at to the smallest detail issue often comes to light that affect constructability or are critical to satisfy the project program and that may require changes to the project program or the budget or both.
By the end of design development, the design drawings and specifications are sufficiently complete to establish and define the facility’s size, function, configuration, spaces, the operation or use of equipment and the materials for all the principal building structures and systems. With this information the project budget schedule and all building plans are finalized
Construction Document Phase
The Construction Document Phase is concerned with the following:
- Compliances with all applicable state and federal codes and statues
- Compliances with University standards
- Verification of building site conditions
- Quality control during the construction phase
- Estimates of all associated costs
Construction documents are complied from design development documents. They include all the architectural drawings and specifications necessary to complete the project, and are the basis of the bid document and the construction contract. The estimated projects costs are reviewed and updated to reflect current construction costs, and are compared with the established project budget. It is no longer feasible to complete the project within the established budget, alternative approaches and practical cost reduction are identified.
All the end of the design phase the project is ready to be constructed and construction budget is ready for your approval. The deliverable of design phase are the design documents, construction documents and the preliminary contract document package. Once the construction budget is approved construction phase begins.

It is proposed to establish a depot-cum workshop. The depot planning is based on following assumptions
- Enough space is available for establishment of depot-cum – workshop
- All inspection, workshop lines and stabling lines are designed to accommodate two transits of 3 car each
- All stabling lines are planned in the proposed depot-cum-workshop assuming adequate space availability. In case of space constraints, if any, stabling facilities may need to be created at terminal stations or elsewhere to carter to the required stability facilities.
In broad terms based on the planned rolling stock requirements, conceptual design on following aspects and will work as a guide for detailed design later.
- Layout of stabling-shed, inspection-shed, minor repair and heavy repair overhauling workshop and cleaning of rolling stock.

BUY, RENT and LEASE options
Before acquiring the equipment, it is essential to explore all the options by considering various parameters namely.
- Company cash flow
- Working capital
- Equipment Utilization and its maintenance
- Obsolescence and replacement
- Operating Conditions
- Scope for repetitive usage
Buying
- Buying results in direct ownership of the equipment
- Acquisition of equipment by buying is done either through cash purchase by using company funds through financing purchase.
- However, cash purchase can have an adverse effect on company’s cash flow as it reduces the liquid asset thus affecting company’s working capital.
- In such cases, financing is explored.
Renting
- It is alternative to direct ownership (i.e., through buying) of the equipment for a shorter period.
- Acquisition of equipment through renting is suitable when the contractor or the construction company requires the equipment for a project task of shorter duration
- Rental period may be a day, a week or a month and may go up to one year
- The rental rates are generally established on daily basis, weekly basis or monthly basis
Leasing
- For a longer period of time as compared to renting
- It is a long-term alternative to direct ownership of the equipment
- The leasing company (i.e., owner of equipment) is known as lessor whereas the user of the equipment is known as lessee.
- Mostly the lease period is more than six months and may run up to years
- Most of the equipment leases are non-cancellable
