Presentation Transcript

Introduction:

Jaipur, the most spectacular land of India, has mountains on the burning desert sand, lakes, forts and temples. Ruled by number of rulers, the city depicts history of honour and chivalry, wealth and power. The city attracts tourists from all across the world for its Hawa Mahal, City Palace, Jantar Mantar and its rich cultural heritage. Jaipur is linked with Delhi, Mumbai, Kota, Bikaner and Agra from National Highways. These highways pass through Jaipur district covering a total distance of 366 kilometres. Introduction

Continue…:

Apart from private travelling, city bus also operates and covers whole city, which makes travelling easy and convenient. Tourists also prefer to travel within the city and nearby places through auto rickshaw, cycle rickshaw and taxis. Though, government has come up with a transit rail project under the name of Jaipur Metro . It is expected to provide faster communication and make the journey less cumbersome. Continue…

We need good public transport:

We need good public transport Traffic in Jaipur has become a very serious problem due to ever increasing number of vehicles on road. We definitely need a very good public transport which alone can solve the traffic problem There are various public transport options available – normal bus, BRT, Tram, LRT, Monorail, Metro Whatever transport system or combination of systems we choose, it must be need based, efficient, affordable, people friendly and fit into the fabric of the city.

Metro:

Metro Metro conjures up a very rosy picture and we may have a feeling that it is high time we now have Metro in Jaipur Nothing wrong, but first we need to be clear about what metro is and what metro is not What Metro is not – Metro is not a magic wand which will make the traffic problems of the city disappear Metro is not a system which Jaipur should have, simply because it is the most advanced mass transport system Metro is not a system which Jaipur should have, simply because it is now a big, growing city – IT, industrial, education hub…. Metro is not a system which Jaipur must have whatever be the impact and price to be paid

Metro:

Metro What metro is Metro is the most expensive mass transport system in the world with a minimum costing of Rs 200 crores per km or more depending on metro type and site conditions Metro operation, maintenance, security is also a very expensive affair Metro train has a high carrying capacity – normal about 600 to1000 passengers and maximum about 1000 to 1500 passengers (depending on number of coaches - 4 or 6) Metro needs to have a certain minimum number of passengers per trip or per hour to make it viable in view of very high capital and operating costs.

Analysis Period..:

The analysis period of the project is taken as 36 years from the base year 2009 as follows: Base Year 2009 Construction period – 2010 to 2014 (5 years) Project opening for traffic – 2015 End of the analysis period –2044 No. of operating years, considered for economic analysis – 30 years Thus, 30 years of operation, in effect, from the start of operation i.e. 2015, has been considered for economic evaluation for the project. Analysis Period ..

Jaipur Metro Proposal:

The first part of the first line stretches up to 9.2 kilometres from Mansarovar to Chandpole with 8 elevated and 1 underground station. The phase II is underground from Chandpole and would connect Ambabari to Sitapura through a 24 kilometre stretch. The corridor II of Jaipur Metro Rail Corporation (JMRC) stretches from Panipech to Sitapura. This line will have 26 elevated stations, covering a total distance of 27 kilometres. The survey approved the installation of Metro rail rolling stock along with signal network in the first phase itself. Jaipur Metro Proposal

Cost Benefit Analysis :

The objective of the cost- benefit analysis is to identify and quantify the economic benefits and costs associated with the project (implementation of 28.55 kms of metro corridors in Jaipur), in order to select the optimum solution along with the economic viability in terms of its likely investment return potential. The cost – benefit analysis is carried out by using the Discounted Cash Flow (DCF) technique to obtain the economic internal rate of return (EIRR %) and economic net present value (ENPV) for the proposed investments linked with the project. Cost Benefit Analysis

Estimated cost Rs 9,100 crore :

The estimated cost of Rs 9,100 crore Metro Rail project is estimated that Ajmer Road, Tonk Road and includes the cost of modifications made to the Corridor. The Phase I and Phase II at Rs 7850 crore to Rs 1250 crore have been underrated. Rajasthan housing board and the Pratap Nagar Metro Rail line to Sitapura Rico Industrial Area. The Phase II is proposed to be expanded so that these areas could also get the benefits of Metro. The expansion will cost Rs 900 crore. In addition to Mansarovar from the Metro Rail line plan Jnsuvydhaoan Rajasthan Sarovar will expand the housing board. Estimated cost Rs 9,100 crore

Continue…:

The project cost stream comprises capital cost, operation and maintenance cost. Cost components considered for the purpose of this exercise include: 1 .Capital cost of infrastructure 2. Operation and Maintenance cost of the system The project cost is taken as Rs. 7531 Crores (which is given by DMRC). The Operation & Maintenance Cost (O & M cost) is assumed as 3% of the project cost/annum. This cost has been converted to economic price by applying a factor of 0.85. Continue…

Social benefits   :

Reduction in accidents and pollution from vehicles Reduced road stress Better accessibility to facilities in the influence area Economic stimulation in the micro region of the infrastructure Increased business opportunities Overall increased mobility Social benefits

Conclusion…:

With the completion of metro project, it would become easier not only for the residents but also for the tourists to commute within the city and nearby places. The duration of travelling will be reduced massively and the journey would be comfortable. It would become easier to find accommodation in different types of Jaipur hotels without any hassles. Tourists can connect to hotels in Jaipur easily after a tiring day in the city. This would prove beneficial for both the government bodies as well as the tourist Conclusion…

Metro is an abbreviation of metropolitan:

Metro is an abbreviation of metropolitan It services relating to urban areas, especially public transport systems. A rapid transit, underground, subway, elevated railway, metro or metropolitan. Railway system is an electric passenger railway in an urban area with a high. Capacity and frequency, and grade separation from other traffic. Rapid transit systems are typically located either in underground tunnels or on elevated rails.

ADVANTAGES OF METRO SYSTEM::

ADVANTAGES OF METRO SYSTEM: 1. Requires 1/5th energy per passenger km compared to road-based system. 2. Cause no air pollution in the city. 3. Cause lesser noise level . 4. Occupies no road space, if underground and only about 2 meters width of the road, if elevated. 5. Carries same amount of traffic as 5 lanes of bus traffic or 12 lanes of private motor cars, if it’s a light capacity system. 6. Is more reliable, comfortable and safer than road system.

METHODLOGY OF CONSTRUCTION:

METHODLOGY OF CONSTRUCTION Locating coordinates. Drilling of earth surface. Casing fixing. Boring. Flushing Cage lowering Concreting

BORE/DRILL WORK OF PILE :

BORE/DRILL WORK OF PILE A temporary short steel casing known as guide casing to be installed for guiding in boring of piles guiding in boring of piles. It also support top loose soil and prevents collapse of top layer due to machinery movement and vibration. Piles are normally drilled using hydraulic rotary Rig machine with special tools like augers and bucket to bore in different site condition. Boreholes should be filled with Bentonite slurry, which is prepared at site being transported using pipes. it will maintain the stability of borehole. Density, viscosity and pH of Bentonite will be tested daily. Density: 1.05 to1.12 Viscosity: 30 to 40 sec. pH value: 9 to 12

Reinforcement cage:

Reinforcement cage It is prepared according to approved drawing and materials. Length and number of main reinforcement and pitch of shear reinforcement (helical stirrups) will be checked and approved by consultant before placing. The minimum area of longitudinal reinforcement within the pile shaft should be 0.4 percent of the sectional area calculated on the basis of outside area of the casing or the shaft. The curtailment of reinforcement along the depth of the pile depends on the type of loading and subsoil strata.

DIMENSION OF PIER/PILE:

DIMENSION OF PIER/PILE Diameter of pile = 1500 m Depth of pile = 34 m Load carrying capacity = 980 tone Size of pile cap = 11 m* 6.5 m * 2.5 m Size of 4 lane pier = 2 m * 2 m Size of pier cap = 5.7 m * 5.4 m* 3.8 m Diameter of metro pier = 1.87 m Number of piles in one pile group = 6 piles

TEST PERFORM FOR CONRETE:

TEST PERFORM FOR CONRETE (1) Compressive strength test :- Compression test is the most common test conducted on hardened concrete.Partly because it is an easy test to perform , and partly because most of the desirable characteristics properties of concrete are qualitatively related to its compressive strength . The compression test is carried out on specimens cubical or cylindrical in shape. The cube specimen is of the size 15 X 15 X 15 cm. (2) Slump test:- One of the most Important nagging site problem is the loss of slump .Slump at mixing point is not of much important. Many users demands the slump value at mixing or batching plant and also specify the slump value after a delay of 1 or 2 or 3 hours . The slump value of concrete is checked when transit mixer is coming if slump value is not coming satisfying then admixtures are to be mixed in the concrete. If slump value of concrete is less than code specified then admixtures is added to the concrete , which increases workability of concrete .
