SUPPLEMENTAL ESTIMATE OF AD RESTCRATICN COSTS
Costs which can be predicted now are at best order-of-magnitude estimates of
the total cost in each Department. The total length of each class of road in
each Department is known, but the extent of damage is not. A judgment has
been made as to the probable percentage of the network which will need repair
in order to assure access to and through conflictive areas. Note this
stipulation. The Tables do not give a total reconstruction requirement. It
attempts to quantify cost of the recovery, primarily in conflictive areas, but
also in parts of the country outside the conflictive zones which are necessary
to provide transport and support for those areas. Work will be carried out in
at least twelve of the fourteen Departments of the country under this plan.
A recent road conditions inventory of accessible roads is in progress and
preliminary data from the inventory has been valuable in confirming earlier
assumpt ions.
Unit costs include major rehabilitation, with work done with the miniumn of
machinery and a large labor force. Unpaved roads should be graveled to try to
improve travel and protect the road base.
The following pa ;s in tables No.1 through 8 show two different methods of
calculating reconstruction costs, using data derived in different ways. The
total costs are r.asonably consistent for the two methods and, for the parts
of the network considered, satisfactory for planning purposes.
Both methods show the greatest need, based on lengths of roads and road
conditions, is in the lower class roads; tertiary and below.
Fortunately, these are the types of roads that lend therrs.7lves most readily
to force account (administration) work usinE labor intensive methods. The
municipalities and the Caminos department resident repre.!sentatives should be
well placed to implement the projects if they are given proper support.
These tables can be used to refine cost estimates as knowledge and experience
is gained in the future. Thre variables enter the calculations and each can
be adjusted independently in future calculations:
(1) Unit costs of rehabilitation for each class of road.
(2) Conditions of roads in each class
(3) Lenght of road in each class and condition.
