Project 1

1)

1A)

• To select the right corridor for Kochi Metro, different possible options were tried.The three main options tried were

 

• Alwaye to Vytilla
• Kalamassery to Thripunithura
• Alwaye to Thripunithura

 

• Based on the expected ridership of the corridor, Alwaye to Thripunithura was selected.
• For this corridor, two-extensions were also tried, one to Kakkanad and the other to Thevra. Impact of these two extensions is marginal on the ridership, hence these extensions are not considered and the corridor from Alwaye to Thripunithura is selected as the best option.
• After carrying out detailed engineering feasibility study for this corridor, it was found that construction of Petta to Thripunithura section of this corridor is not feasible till improvement to existing road infrastructure between these two places is done by the concerned authorities.
• Accordingly, ridership on the truncated corridor from Alwaye to Petta was worked out which is marginally less from ridership of Alwaye to Thripunithura Corridor.

 

 

 

  

 

1B)

ROB’s AT PULLEPADY AND NEAR KSRTC BUS STAND

• Two Road-Over-Bridges (ROBs) across the railway track between Ernakulam town and Ernakulam junction railway stations – one at Pullepady level crossing and the other near KSRTC bus stand connecting Mullassery Canal Road and Salim Rajan Road on either sides of the railway track have been planned by GCDA.
• Completion of these two ROBs will substantially relieve the present traffic congestion on MG Road and Baneji Road as well as on Salim Rajan Road by diversion of traffic towards Kaloor, Pallarivattom, Kakkanad, Thammanam, Vytilla, etc.
• Since construction of Kochi Metro structures on the median of Banerji Road and MG Road will hamper the movement of road vehicles during the execution period, the State Government and the GCDA authorities have been apprised the necessity for early completion of the above two ROBs.

 

PROPOSED FLYOVER AT EDAPALLY

• At present Edapally junction is a staggered intersection where Alwaye – Ernakulam route is intersected by NH 47 – bypass and NH17 within a distance of 70m and hence it causes a lot of traffic confusion.
• There is a proposal by the National Highway Department to rectify the staggering to make a four-legged intersection. There is another proposal by GCDA to construct a four-lane flyover on the Alwaye-Ernakulam Road.
• In case the proposal of National Highway Department to rectify the staggering to make 4-legged intersection is taken up, it will not affect the Metro alignment. If later, the flyover proposal by GCDA on Alwaye – Ernakulam Road at this junction is also taken up, the Metro alignment will go alongside it. This way Metro and flyover will not obstruct each other. If slight revision of Metro alignment is required, this can be done without any problem.

 

FLYOVER FROM PALARIVATTOM JUNCTION AT NH 47 BYE - PASS TO HIGH COURT JUNCTION

 

• The proposal aims to relieve traffic congestion on the major city road which has the highest volume of traffic by creating a flyover or a grade separator to take through traffic.
• The flyover will be 4582m long and is to be designed to carry 2 lanes and hence its width is kept as 8.5m supported on a central pillars. Width of existing road at this location is not adequate to accommodate the proposed flyover along with Kochi Metro.
• Besides, with the construction of Kochi Metro which will relieve substantial amount of traffic moving on the existing road, the need for flyover may not be necessary. It is, therefore, suggested that the State Government may give up the proposal of fly-over at this location.

 

PROPOSED FLYOVER AT VYTILLA

• GCDA has a proposal for constructing flyover at Vytilla Junction across NH 47 bye-pass, whose alignment will be the same as that of Kochi Metro at this location.
• Road width at this location is not adequate to accommodate proposed flyover as well as Kochi Metro.   It is, therefore, suggested that the Metro should be constructed along the Median of road, while GCDA should change its proposal of flyover to that of an underpass below the NH 47 bye-pass.
• Changing the fly- over to under-pass will be much more cost effective for the State Government, than to allow construction of flyover as well as Kochi Metro with double elevation at this location. It is, therefore, strongly recommended hat GCDA should revise the above proposal and plan construction of the underpass along with theconstruction of Kochi Metro. Kochi Metro will be designed to cater for the underpass.

 

1C)

Location of Depo

It is proposed to establish a depot- cum- workshop at Muttom. The Depot planning is based on following assumptions:

• Enough space is available at Muttom for establishment of a Depot- Cum- workshop.
• All inspection, workshop lines and stabling lines are designed to accommodate two train-sets 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 cater to the required stability facilities.

 

1D)

There is no requirement of tunnel route. The entire route is elevated. Maximum of the route is through the center of the road.

 

1E)  Alwaye-Petta Corridor

1. Route Length (between dead ends) 612 km

• SUMMARY

Project Name : Construction of Kochi Metro Phase 1

Project Manager : XYZ

Project Start :2013

Project End : 2017

Total estimated cost (without taxes) : Rs 385 crore

 

• Goal

Kochi is the city of the state Kerala in India. Today the city does not have any public transport system other than bus services. But this traffic volume is sure to grow multifold in very near future due to its new status as capital city. Due to high land cost and extreme reluctance of the public to part with their lands, widening of roads to accommodate Mass Transit System at road level is almost unthinkable therefore the choice of Mass Transit System for Kochi city must be zeroed down to a Metro System. Metro system is recommended which will serve the needs of the city for all time to come like it will help to improve the transportation and reduces traffic, cost, and pollution issues

 

• Scope

To construct elevated , at grade metro stations

 

• Project Objectives

The key goal of this project is to develop a metro in densely populated area of India in order toget following benefits from it.

• Reduce Air Pollution Issues
• Save Travel Time
• Provide a reliable and convenient transit service
• Mitigate the growth of traffic congestion
• Improve mobility for non-drivers
• Parking Cost Savings
• Consumer Savings and Affordability

High level scope of design consultants for Station Construction

 

Construction of the Stations

5.4.6.1 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)

 

5.4.6.2 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.

 

5.4.6.3 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 insitu 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.

 

5.4.7 Grade of Concrete

It is proposed to carry out construction work with design mix concrete through computerised automatic Batching Plants with following grade of concrete for various members as per design requirement/durability considerations.

1. i) Pile cap and open foundation - M -30
2. ii) Piers - M –40/M-50

iii) All pre-cast element for viaduct and station - M -45

1. iv) Cantilever piers and portals - M -45 - M -60
2. v) Other miscellaneous structure - M - 30

For all the main structures, permeability test on concrete sample is recommended to ensure impermeable concrete.

 

5.4.8 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).

 

5.4.9 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 sides 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:

1. Preliminary action for diversion of utility and preparation of estimates there of
2. 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.

 

5.5 Soil Characteristics & Field Investigation

5.5.1 Field Investigations

• Four boring rigs with all requisite equipments and accessories were mobilised at the work site. A team of technical personnel with skilled labours were also deputed.
• Fifty one boreholes of 150mm diameters were bored to a maximum depth of 45.0 metres below the existing ground level from Alwaye to Thripunithura. 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 5.5.2 Laboratory Investigation

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 the 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 programmer researches current and projected needs in such areas as information and instructional technology, academic teaching methods, privacy and 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 or projects-in-planning, and the need for corollary projects, such as parking lots or new utilities services. State of Michigan building requirements or restrictions, all life safety, fire, environmental and barrier-free code issues are identified.

The project program, the end result of the Programming Phase, describes how the finished project will "work": how it 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, HVAC, plumbing and electrical).
• Interior and 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 determines the areas, physical requirements and relationships of all the required building spaces and components, confirms or revises the total building square footage, the total project budget and the project schedule and occupancy dates.

It provides control strategies for all equipment and systems relating to building services such as security and fire alarms, and defines the technical requirements for phones, data, cable and audio/visual needs.

The schematic drawings—floor plans, site plans and building elevations—are reviewed and refined for functionality, usability, required adjacencies, code compliance, security, safety and aesthetics. The project program and the 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 and exterior building materials and finishes.
• Furniture and equipment selection and layouts.
• Cabinetry and custom fabrications.
• Lighting and 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 looked at to the smallest detail. Issues often come to light that affect constructability or are critical to satisfying the project program, and that may require changes to the project program or to 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:

• Compliance with all applicable state and federal codes and statutes.
• Compliance with university standards.
• Verification of the building site conditions.
• Quality controls during the Construction Phase.
• Estimates of all associated costs.

Construction documents are compiled from design development documents. They include all the architectural drawings and specifications necessary to complete the project, and are the basis of the bid documents and the construction contract. The estimated project costs are reviewed and updated to reflect current construction costs, and are compared with the established project budget. If it is no longer feasible to complete the project within the established budget, alternative approaches and practical cost reductions are identified.

At the end of the Design Phase, the project is ready to be constructed and the construction budget is ready for your approval. The deliverable of the Design Phase are the design documents, construction documents and the preliminary contract document package. Once the construction budget is approved, the Construction Phase begins.

It is proposed to establish a depot- cum- workshop at Muttom. The Depot planning is based on following assumptions:

(i) Enough space is available at Muttom for establishment of a Depot- Cum- workshop.

(ii) All inspection, workshop lines and stabling lines are designed to accommodate two trainsets of 3- car each.

(iii) 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 cater 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 repairs and heavy repair overhauling

workshop and cleaning of Rolling Stock.

• Operational and functional safety requirements.
• Ancillary buildings for other maintenance facilities.
• Electrical & Mechanical Services, power supply and distribution system.
• Water Supplies, Drainage & Sewerage.

 

Land of 12.8096 ha. for car maintenance depot at Muttom and construction depots, is proposed to be acquired. The depot is planned at ground level. Costs have been worked out for various items of building, elevated structures, tracks, boundary wall & plants machinery etc.

BUY, RENT and LEASE Options

 

Before acquiring the equipment, it is essential to explore all the options by considering various parameters namely,

• Company’s 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 or 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 options are explored

 

Renting

• It is an 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 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 the 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.
