NEED FOR THE PROPOSED EXPANSION SHOULD BE JUSTIFIED IN DETAIL

Project details:-
The Aerial Ropeway Project named ‘Pavagadh Udankhatola’ will be developed at Pavagadh in
Panchmahal District, State Gujarat. The project site stretches from the hilltop at Pavagadh village
to the station near the Maa Mahakalika Temple.
Purpose:-
The project will be developed as a quick, reliable and environment friendly mode of
transportation for carrying pilgrims from the Pavagadh village to Maa Mahakalika Temple.
Location of the Project:-
The site is located at Pavagadh. Lower terminal is located in the land adjacent to upper station
(land is already possessed by Usha Breco limited) to existing ropeway and upper station adjacent
to Maa Mahakalika Temple.
Need of project:
• Maa Mahakalika Temple located at Pavagadh in District Panchmahal attracts lacs of pilgrims and
tourists throughout the year from all over the country.
• The existing Ropeway at Pavagadh is constructed from Machi to Pavagadh.
• The pilgrims have to accomplish a steep journey to reach the main destination, Temple. It takes
more than 45 minutes to climb the Temple. Hence the need of ropeway extension from Hill Top
to the Temple is always felt and demanded by all sections of pilgrims.
• Excessive time consumed for people, hence wastage of a productive day for some.
• Excess rush in the temple during festival days / holidays can be eased out by one way ropeway
ride. Hence leading to safety.
• During rush time, the pilgrims movement to the temple can be regulated at ropeway waiting
halls.
• Proper amenities shall be provided to the pilgrims.
• Quick movement of police / district administration / Forest officials in case of need / emergency.
• Better and more organized impression to the pilgrims, as well as the foreigners, who visit in
substantial numbers to the world heritage site.
• Control of solid waste will be easy, as littering would not be possible, as large number of people
would travel by ropeway
• The additional Passenger Ropeway will link the Pavagadh village to the hilltop near the Kalidevi
Temple and will quickly & comfortably transport the pilgrims to the temple
• Now, we are going to add new of 250 meters long Ropeway with a lift of about 60 meters will
have a carrying capacity of 800 passengers per hour and will transport the pilgrims to the hilltop
in about 2 minutes against a steep climb of over 45 minutes.
• In addition to providing, safe, comfortable and quick Darshan to all pilgrims, the ropeway will
also help in crowd management at temple complex during the peak days.
• Ropeway being highly environment friendly causing almost no noise, water or air pollution, is
the most efficient and economical mode of transportation in these hilly terrains where other
means of transport do not exist.

All activities involved in design and constructions are being detailed in proper sequence as follows:-
ACTIVITIES CONSIDERED DURING CONSTRUCTION OF ROPEWAY
Topographical Survey

The topographical survey was conducted with Total Station and Auto Level. Bench Marks were
established at regular interval and the survey covered a strip of 20 m width with longitudinal cross
sections taken at required interval for designing needs. The Topographic survey information was then
translated into digital terrain model of the area using suitable mapping software.

Topographical surveys included the following:
a) Control Point Survey
b) Traversing
c) Cross-section Survey
d) Establishing Bench Mark

METHODOLOGY FOR TOPOGRAPHICAL SURVEY
Topographical survey was carried out with Total Station, Auto level and checked with GPS, state-of-the
art instruments. The survey methodology involved the following sequential steps:
A} Control Points:
Establishing control points in the form of temporary bench marks (TBM) at regular intervals on ground
and running traverse along tentative alignment using Total Stations. Reference Pillars consisting cement
concrete pillars with central nail point; have been fixed at regular intervals depending upon site
conditions.
B} Traversing:
Connecting all control points with one or more Benchmarks using precision Auto Level and Total Station.
C} Cross-section:
USHA BRECO LIMITED FEASIBILITY REPORT, PAVAGADH ROPEWAY

Taking detailed longitudinal cross sections using Total Station. The main features captured in the cross-
sections were:
 All natural ground break-point within the Right-of-Way (ROW)
 Property lines within ROW.
 All crossing like power, road, river etc.
The data for each survey point were recorded in terms of Northing and Easting and Elevation to
an accuracy of 1mm.
D} Establishing Bench Mark:
Due to non-availability of Survey of India reference bench mark, bench mark elevation was carried from
BRO BM pillar. Based on this reference BM, TBMs were established along the proposed road alignment,
using auto levels and double leveling method.
In addition, all TS stations were also leveled. Permanent cement concrete pillars were established at
regular intervals.
The survey data collected in the fields mapping software were downloaded in text file format and
converted to graphic files using suitable software. Topographical survey data were eventually presented
for Computer-aided-design (CAD) in the form of AutoCAD design files in 1:1 scale.
The objectives of the survey are to :
 Enable a definitive design to be made for Ropeway
 Profile calculation for all ropeway sections
 Rope line calculation
 Enable a definitive influence to be made for the profile of the approach Ropeway.
 Define clearly and contractually the extent of the Ropeway work to be done.
 Enable quantity estimate to be prepared.

ROPEWAY ALIGNMENT SURVEY
The Topographical Survey was carried out to map the topographical features of the approach
road to ropeway and Ropeway location on the abutting land and abutting areas. It is aimed at

preparation of the Base map of the area, to facilitate review of alignment layout and preparation of plan
for Ropeway.

GEOTECHNICAL INVESTIGATION

Introduction:
A typical geotechnical engineering study begins with a review of project needs to define the required
material properties. Then follows a site investigation of soil, rock, fault distribution and bedrock
properties on and below an area of interest to determine their engineering properties including how
they will interact with, on or in a proposed construction. Site investigations are needed to gain an
understanding of the area in or on which the engineering will take place. Investigations can include the
assessment of the risk to humans, property and the environment from natural hazards such as
earthquakes, landslides, sinkholes, soil liquefaction, debris flows and rockfalls.

Ground Improvement refers to a technique that improves the engineering properties of the soil mass
treated. Usually, the properties that are modified are shear strength, stiffness and permeability. Ground
improvement has developed into a sophisticated tool to support foundations for a wide variety of
structures. Properly applied, i.e. after giving due consideration to the nature of the ground being
improved and the type and sensitivity of the structures being built, ground improvement often reduces
direct costs and saves time. A geotechnical engineer then determines and designs the type of
foundations, earthworks, and/or pavement sub-grades required for the intended man-made structures
to be built. Foundations are designed and constructed for structures of various sizes such as high-rise
buildings, bridges, medium to large commercial buildings, and smaller structures where the soil
conditions do not allow code-based design.

Foundations built for above-ground structures include shallow and deep foundations. Retaining
structures include earth-filled dams and retaining walls. Earthworks include embankments, tunnels,
dikes, levees, channels, reservoirs, deposition of hazardous waste and sanitary landfills.

Subsoil investigation is carried out at field by making borehole and collecting disturbed and undisturbed
samples accompanied by Standard Penetration Test. Laboratory test results of samples are
systematically presented in different tables and graphs.
