temporary bypass roads for its own use. Where such access roads do not fall on
the Right-of-Way, CONTRACTOR shall obtain necessary written permission
from land owners and tenants and be responsible for all damages caused by the
construction and use of such roads, and at no extra cost to COMPANY,
Wherever rocky terrain is encountered, grading shall be carried out in all types of
solid rocks which cannot be removed until loosened by blasting, drilling, wedging
