Labour
A large pool of unskilled labour is available although it shrinks at times of
crop harvesting. There is a shortage of skilled labour.
Construction Material
Except for some local soil and sand for embankment construction, all
construction materials will require transportation to the project area.
Single grade fine sand is available from rivers/streams within the project area.
Well-graded coarse sand is available from the huge fan deposits in the
northern part of Sylhet.
Good quality stones as boulder and gravel are available from the fan deposits
of rivers in the northern part of Sylhet. No boulders and stones are available in
the project area.
There is a scarcity of good quality stone in the country and sometimes stones
are required to be imported.
Well-burnt brick aggregates are used in the sub-base and lower part of the
base. Brickfields exist within reasonable distances from the project sites. Good
quality well-burnt bricks can be available if coal burning is ensured. Coal may
require importation.
Bitumen (80/100 grade) is produced only in one refinery in the country. The
refinery may also supply bitumen of grade 60/70 if the order is placed for
sufficient quantity and well in advance of the requirement. The production of
the refinery is not adequate to meet the demand of the country. It may require
importation.
