This is a presentation about the management of the large Infrastructure projects such as trasnport, mining, industry, etc. Starts with the basics of the project management and then goes on to the Metro project- the issues faced and the execution of various activities. This was presented at the invited talk at the head quarters of the National Aluminium Comapany, Bhubaneswar on 11th Sep25. The programme was started with address by CMD(Sh B P Singh) and was organised by CVO(Sh Pranabjyothi Nath, IAS).
Characteristicsoftypicalproject:
Temporary - have a definite beginning and an end.
Unique – no two projects are identical.
Predefined goals & objectives – financial/ social/ economic.
Budgets & schedules – prefixed budget and time frame.
Uses Resources including Manpower – these are limited.
Quality/ performance - determined at beginning.
Faces Risks – known and unknown risks
Project : Converting vision into reality.
A set of activities are undertaken to meet the specified
objectives for the changes.
Costsaredirectlyrelatedtoproject:

3D PRINTING
It utilizes robotics to deposit

effectively creating walls, floors, and
even roofs with speed.
Can prefabricate essential supports and
reinforcements that are seamlessly
integrated into the structure.
The next big leap for the construction
sector.
With an estimated urban housing

SUCCESS DEPENDS ON SUCCESSFUL BIDDING
AN EXAMPLE OF SUCCESSFUL BIDDING
Flagship greenfield highway project aimed at
revolutionizing road connectivity between India’s two
largest metropolitan cities.
Length:1,386 km
Timeline:Started in Mar 2019,
Original completion targeted was January
2023. Substantially completed (about 82%).
Cost:Estimated at around ₹1 lakh crore. Likely to be
completed within the estimated cost
Some work balance in few stretches affected by land
acquisition. Likely to be completed by 2026 or 2027
DELHI–MUMBAI EXPRESSWAY
Will reduce travel time from Delhi to Mumbai from 24
hours to 12 hours.
Designed for 8 lanes, expandable to 12 lanes.
52 packages (contracts)-31 awarded on EPC basis,
21awarded on Hybrid Annuity Model (HAM)
Runs parallel to the Western Dedicated Freight
Corridor (DFC), forming the backbone of the Delhi–
Mumbai Industrial Corridor(DMIC).
Will connect major cities enroute and provide modern
wayside amenities.
DELHI–MUMBAI EXPRESSWAY
FEATURES
5D BIM integrated with common data environment accessed by
all stakeholders is utilised for real time monitoring and
predictive analysis to control cost and time over run. Quick
issue detection and mitigation are done online.
DELHI–MUMBAI EXPRESSWAY
As per hon’ble Union Road
Transport and Highways
Minister Shri Nitin Gadkari ji-
"As of February 2025, a total
length of 1,156 km out of
1,386 km of the Delhi-
Mumbai Expressway has
been completed across
States, Out of this, 756 km
has been operationalized."
Mumbai–Ahmedabad High Speed Railway Project
India’s largest ever infrastructure project, supported by
Japanese funding and technology
Cost: Around ₹1.08 lakh crore, with significant soft loan
support from Japan.
Length: 508 km
Technology: Shinkansen based on Japanese expertise.
Speed: Trains will run at 320 km/h operating speed,
reducing travel time from 7 h to 2.07hr with limited stops
(with all stops it will be 2.58h)
INDIA’S BULLET TRAIN PROJECT
Salient features:
12 state of the art station. 1
st
station is UG at BKC.
94% alignment in elevated. 26KM is UG including
longest tunnel of India-21KM which is 7KM under
sea(Thane Creek)
1435MM Guage(Standard guage), 4.5M Track Cente
Timeline:
Project launched in 2017 but work actually started in
2022. Targeted to be completed in 2025 but will take 3-5y
more
Land acquisition done and construction works ongoing,
with phased commissioning expected between 2027–2028.
INDIA’S BULLET TRAIN PROJECT
Progress:
Around 250 km of viaduct completed. Work
substantially completed in Gujrat state.
Target is to run services on some sections
between 2027–2028.
The BIM concept has been used with substantial
use of technology for monitoring and project
management and record keeping. However,
whether the 5D BIM has been fully utilised or not is
not known.

Phase II: 44KM
Extension of both Orange and Aqua lines.
Phase II work commenced in 2020–21.
Target for commissioning: 2026 (originally), Later
revised to 2027
One of the first mega projects in India to adopt 5D BIM>
Used primavera for scheduling, RIBiTWO,

•Challenges due to proximity of canal.
•750mm diameter contiguous bored piles
were used with 3m edge distance from
canal.
•These were designed to withstand a fill
height of 5m approx. for a length of
around 40m.

CENTRAL PORTION OF METRO STATION
•Launching was to be done across 7 railway
tracks and canal at 3 levels.
•It was decided to go with steel as material for
construction as that is lighter, easier to erect
and can span long.
•6 pile group of 1200mm diameter piles with
staggered arrangement was used.
•Width of the pile cap could be restricted
within 3400mm which could be just adjusted
within the series of tracks keeping safe
distance from the trains.
258 hours of block were
taken on 93 days to
complete piles and pile
