supervision and increase oversight costs. WINRIP adopted a corridor approach, whereby segments are grouped and located in sequence, thereby easing technical
supervision and third party monitoring.
For WINRIP the design and design checking processes have been strengthened. A comprehensive Design Specification, and Final Engineering Design and preparation of
associated Bidding Documents for WP 1 is being undertaken directly by the Project Preparation Consultants PPC. The implementation arrangements have been clarified to
enable the consulting engineers in civil works contracts to have clearer authority and responsibility and thus improve accountability for approving and paying for completed
works. Monitoring of the effectiveness of supervision procedures will be undertaken by the DSC and overseen by the CTC. Technical audits will also address quality of work issues, and
will be used to verify the adequacy of all works. The Project Management Manual is prepared in separated document ready for WINRIP implementation.
1.7.2 Benefits and Target Population
Project beneficiaries will be road users in participating provinces, districts and towns in the four provinces included in the WINRIP region North Sumatra, West Sumatra, Bengkulu and
Lampung. Direct beneficiaries of the project include people who live in the vicinity of the project area who directly benefit from the improvement of the road sections financed by the
project. The project road sections traverse 12 districts

with a total population of more than 4 million

of which around half are women. In addition, the betterment and maintenance of roads will create employment for people.
i. Improved road conditions and connectivity between major centers and modes of
transport will lower transport costs for passengers and freight. This will reduce the cost to local industries and of inputs to local agriculture, and the cost of transporting
products to markets, and provide a significant stimulus to regional economic development;
ii. Improved transport services in the provinces concerned will have a significant impact
throughout Sumatra, given that the road improvements are to the main arterial roads on the island. Indirectly the benefits will impact on isolated communities with low
income populations. Improved roads and accessibility will increase access to jobs, health, social and educational facilities in disadvantaged rural areas as well as in the
administrative, economic and social centres.
iii. The project will strengthen the ability of central and regional based road networks
management units to manage the road and bridge assets for which they are responsible. The projects emphasis on transparency and accountability will impact on
governance in all areas.
1.7.3 Project Economic Evaluation
An economic evaluation has been undertaken of almost all civil road work components. Nearly all projects proposed for inclusion in W
INRIP have an EIRR greater than 15: this being the normal minimum required. The few projectscorridor links which do not meet the

15 EIRR standard are justified by additional criteria, including broader socio-economic and development benefits. Many road sub-projects have EIRRs well above the minimum
indicating urgency for implementation for economic efficiency. Annex 3 provides details of the economic evaluation for the road works, the largest component of the project. Economic
evaluations have not been carried out for bridge works. These works have been selected for reasons of necessity to replace ailing existing bridges or provide bridge capacity compatible
with the associated road works.
