Xn a larger program, t3is may be realistic. A logging
vehicle! operating in the Bay Region is assumed to last for five
years and one operaZincj An the Ccnlraf Range is assumed to last
for aaly @kme years [Appendices 4.4.1 and 4.4.2, Table 9).
These nay prove to be cansen-a25ivs estimates.
The type sf civil works constructed By the project is
discussed in Sections 2.6 and 3.6. After July 1984, the
canstmetion of civil works at Groundwater Project rites became
ma responsibility cf the Bay Region Acjricultural Development
Project and the Central Rangelands Sevelopnent Project,
Dependin9 upon the design and facilities provided, the cost of
civil works can exceed $40,000 per site, as quoted to BRADP in
response to a recent tender advertisement, and may be as 9igh as
$100,000, 9s installed by GTZ In the Central Rangelands.
The figures intruded in the model represent the cost of the
less a-itiaus facility built by WDA and constructed from
locally available materials (Appendices Q ,4,1 and 4.4.2, Table
6). It consists 05 a water storage tank, two or three troughs,
and a Sank af taps.
A pump crew of five is assued to require a total of 5 days
to install a diesel punp ax3 4 days =o install a hand pump in
the Bay Region (Appendix 4.4.1, Tables 7 and 8)- In the Central
Range these times are extended by two days to allow for extra
travel.
The pumps installed by the project were Honelift with
Lister diesel engines, and Mono hand pumps. The complete diesel
assembly costs approximately $14,500, and the handpump cast
$3,600. Ordered in sufficient numbers to fill containers sent
from the Cnited States, the additional cost of overland and sea
freight is approximately 5%.
