2. Site access

• Access to Sentech sites is mostly by means of gravel roads. In some instances,

the roads may be paved with a bituminous surface in other instances maybe

concrete or concrete strips roads. The contractors are requested to use 4 x 4

vehicles to access our sites.

• Although we try our best to maintain these roads as best as possible some of the

paved and concrete roads cannot be accessed with an ordinary vehicle.

• Some may be very steep in places with very tight turns which would make access

difficult for ordinary vehicles.

• The mast and Sentech’s property and buildings are fenced off to restrict

unauthorized entry.
