F. DETAILED ENGINEERING DESIGN SERVICES FOR THE
UPGRADING OF THE SWIP WORKSHOP
TERMS OF REFERENCE
Background
1.
The Government has identified solid waste in [] as a
priority problem and has requested the World Bank to assist
in the implementation of the Proposed [] Solid Waste
Management Project ([]). The objectives of the [] are: (1)
to improve the efficiency of collection and disposal of solid
waste and (2) to improve the environmental conditions in [],
through the utilization of waste transfer stations in
collecting solid waste, the adoption of the sanitary landfill
method of disposal, and the eventual closure of all open
dumps in [].
2.
One
of
the
problems
inherent
in
the
collection/transport, transfer and disposal system is the
lack of facilities or depots for major repair and maintenance
works
for
government-owned
compactor
trucks,
storage
containers/trailers and other types of collection vehicles,
as well as transfer station and sanitary landfill vehicles
and equipment that require such services.
3.
In light of the lack of facilities and, more
importantly, in order to protect its capital investments, the
Government has decided to include in the proposed [] a
component for the rehabilitation and upgrading of the
existing Solid Waste Improvement Project (SWIP) Workshop to
serve as a repair and maintenance facility primarily for
those vehicles and equipment acquired with World Bank
financial assistance and secondarily, for certain qualified
government-owned vehicles and equipment that would require
regular and periodic servicing and maintenance as part of an
approved preventive maintenance program.
4.
The SWIP Workshop/Depot is located at a _____ square
meter site located at [] in []. It was a component of the
World Bank- assisted SWIP Program which was implemented in
19__ and was intended to be a repair and maintenance depot
for 10 compactor trucks, 6 arm roll trucks and the containers
that were acquired with the vehicles during that time.
It
was then projected that the depot had been able to service 50
units (including container vans) under the SWIP Program.
5.
At present, the depot is additionally being used as a
garage workshop for 116 units of various collection/storage
equipment under a JICA grant. Repair and maintenance works
are performed on these equipments when needed.
6.
It is anticipated that in the future additional units
of vehicles/equipment under other grants/loans will be
serviced by the SWIP Workshop. There is therefore a need to
re-assess the utilization of the workshop considering space
limitations as dictated upon by the size of the property.
7.
With the projected volume of servicing required, it is
anticipated that the SWIP Workshop will have inadequate
repair and maintenance facilities and personnel to operate
the facility when it is utilized at its maximum capacity.
8.
It is to fill this need that the upgrading of the SWIP
workshop was conceived to become a part of the [] for which
World Bank-assistance is being sought.

life of 25 years and be able to withstand seismic events.
k. Ensure that all demolition, rehabilitation and reconstruction plans and phasing are clearly specified,
details clearly drawn, and safety and quality control
measures fully identified.
