Outline
❖Necessity, advantages and disadvantages of PPP (Public Private Partnership),
❖Bus Rapid Transit System (BRTS)

1. Necessity of Mechanization
a) Due to use of advanced construction equipment, there is uniformity in work quality and productivity, which
cannot be maintained by labour intensive work.
b) Mechanism and automation provides the skilful management in the various stages of construction work.
c) Mechanisation is more suitable under extreme work condition and in case of difficult terrain, Which is not
possible by labour intensive work.
d) Targeted time scheduled can be easily be maintained by mechanization which is not possible due to labour
strikes, trade union pressure and shortage of efficient labour
e) Large scale work like bridges, dam, high rise building, express highway etc. can be done by mechanization.
f) Infrastructure development for any area or region can be done more fast with the mechanization.

2. Public–Private Partnership
▪A public–private partnership (PPP) is a cooperative arrangement between two or more
public and private sectors, typically of a long-term nature.

2.1 PPP Models
❖Design-Build (DB):
✓The private-sector partner designs and builds the infrastructure to meet the public-sector partner's
specifications, often for a fixed price. The private-sector partner assumes all risk.
❖Operation & Maintenance Contract (O & M):
✓The private-sector partner, under contract, operates a publicly owned asset for a specific period of time.
The public partner retains ownership of the assets.
❖Design-Build-Finance-Operate (DBFO):
✓The private-sector partner designs, finances and constructs a new infrastructure component and
operates/maintains it under a long-term lease. The private-sector partner transfers the infrastructure
component to the public-sector partner when the lease is up.

2.1 PPP Models
❖Build-Own-Operate (BOO):
✓The private-sector partner finances, builds, owns and operates the infrastructure component in perpetuity.
The public-sector partner's constraints are stated in the original agreement and through on-going regulatory
authority.
❖Build-Own-Operate-Transfer (BOOT):
✓The private-sector partner is granted authorization to finance, design, build and operate an infrastructure
component (and to charge user fees) for a specific period of time, after which ownership is transferred back
to the public-sector partner.
❖Buy-Build-Operate (BBO):
✓This publicly owned asset is legally transferred to a private-sector partner for a designated period of time.

2.1 PPP Models
❖Build-lease-operate-transfer (BLOT):
✓The private-sector partner designs, finances and builds a facility on leased public land. The private-sector
partner operates the facility for the duration of the land lease. When the lease expires, assets are transferred
to the public-sector partner.
❖Operation License:
✓The private-sector partner is granted a license or other expression of legal permission to operate a public
service, usually for a specified term. (This model is often used in IT projects).
❖Finance Only:
✓The private-sector partner, usually a financial services company, funds the infrastructure component and
charges the public-sector partner interest for use of the funds.

3.1 Bus Rapid Transit System (BRTS)
❖Bus rapid transit System (BRTS), also called a busway or transitway, is a bus-based public
transport system designed to improve capacity and reliability relative to a conventional bus
system Operation License.
❖The first BRT system in the world, was the Transitway system in Ottawa, Canada, which
entered service in 1983.
❖The first BRTS in India is Rainbow Bus Rapid Transit System in Pune, started in 2006

3.2 Need for BRTS
❖Unless a bus-only lane is present, a bus cannot go faster than other road traffic. This may become
especially apparent during rush hour or other periods of substantial congestion.
❖With the exception of stops that employ bus bulbs, when a bus stops to pick up or discharge
passengers, it exits the flow of traffic and so cannot resume travel until it is safe to merge back in.
❖Because nearly all conventional bus routes employ request stops, a bus driver must take time to
scan approaching stops for passengers waiting to board, as well as drive slowly enough to stop
safely should passengers be present.
❖Few bus networks are fareless or use proof of payment fare collection, so a bus must wait to
depart a given stop until all passengers boarding at that stop have paid their fare. In the interest of
reducing fare evasion, buses typically only have one farebox onboard (located inside the front door,
near the driver), so this can take a relatively substantial amount of time when use is heavy.

3.3 BRTS Features
❖Dedicated lanes and alignment
❖Off-board fare collection
❖Intersection treatment
❖Platform-level boarding
❖High capacity vehicles
❖Quality stations
❖Prominent brand or identity
