The Government of Tanzania, through Reli Assets Holding
Company (RAHCO), has set aside funds for the operation
of RAHCO during the financial year 2017/18. It is intended
that part of the proceeds of the fund will be used to cover
eligible payment under the contract for

training of rolling stock for a standard
gauge railway (SGR) railway system to
operate in the Tanzania Central Railway
Corridor. Characteristics of the SGR line
are that it will be of 60kg/m rails fixed on
monoblock concrete sleepers, electrified
with operating speeds of 160km/h for
passenger trains, and 120km/h for
freight trains.
The line has capacity to handle
2 000m-long trains with axle
loads of 35t per axle, with a design
radius of 1 900m and maximum
grade of 1.6%. Each to be installed with
ETCS Level-2 with GSMR. The schedule of requirements is
categorised into several lots: Lot 1: freight trains 1) electric
locomotive: 6500HP × 14 and diesel locomotive 6500HP
× 2 and 2) departmental trains: electric locomotives 3000HP
× 3 and diesel locomotive 3000HP × 3.
The project includes the supply, testing, commissioning, and
training of rolling stock for a standard gauge railway (SGR) railway
system to operate in the Tanzania Central Railway Corridor.

The Federal Government of Nigeria received a loan from the
African Development Bank (AfDB) in May 2009 towards the
cost for the implementation of the Programme for Transport
Facilitation along the Bamenda (Cameroon)–Enugu (Nigeria)
Road corridor. It intends to apply part of the proceeds to
payments under the contract for consultancy services for the
design and supervision of the asphaltic concrete overlay of
Abakaliki–Mbok (Ogoja Junction) and Ikom–Mfum roads along
the Bamenda (Cameroon)–Enugu (Nigeria) Road corridor.
The services to be performed under the programme shall
comprise design and supervision of the asphaltic concrete
overlay of Abakaliki–Mbok (Ogoja Junction) and Ikom–
Mfum, involving road rehabilitation in the two prioritised
areas along the Bamenda (Cameroon)–Enugu (Nigeria) Road
corridor. The assignment consists of design that comprises
environmental and social impact assessment; road safety,
preliminary design and possible re-alignment of sections of
the roads; and economic and financial analyses. The works
supervision on existing alignments, as well as realigned
portions, consists of scarification and repair of failed areas,
site clearance, earthworks, new culverts, repair to existing
bridges, protective works, granular sub-base, crushed stone
base course, asphaltic concrete surfacing, side drains, road
markings, and road furniture.
Traffic management as well as social and environmental
measures are also important aspects of the projects. The
assignment shall mainly consist of design and supervision of
the asphaltic concrete overlay of the two sections of the road
corridor — to be funded from the AfDB loan — and is to
run from 2018 to December 2019; and monitoring during
the defects liability period of 12 months that would terminate
in 2020. The objectives of the consultancy are to carry out
an assessment of the road sections in question, aimed at
identifying any failed areas and proffering appropriate repairs;
to prepare a detailed design of the rehabilitation works and
tender documents for the selection of the works contractor;
and to monitor compliance of the contractor to be selected to
ensure that the works are carried out in accordance with the
contract and to the satisfaction of the employer.
The total man-month input of the consultant is estimated at
98.5 man-months. The employer — Road Sector Development
Team (RSDT) under the Federal Ministry of Power, Works &
Housing — now invites consultants to indicate their interest
in providing these services.
