curb and gutter, sidewalk and median bar-
rier. Grade stakes for finished subgrade will
not be set until the grade established by the
slope stakes is constructed to within 0.3 foot
of the finished subgrade elevation.
Minor structures and retaining wall stak-

shall be responsible for the accuracy of all
the vertical and horizontal control it trans-

when required, provide access to abutments,
piers or other locations, and shall furnish
working platforms that meet applicable
safety requirements so the Engineer's duties
can be performed.
The Contractor shall be held responsible
for the preservation of all stakes and marks,
and if any are destroyed, disturbed or
removed by the Contractor, subcontractors,
or suppliers, the cost of replacing them will
be charged against the Contractor and will
be deducted from the payment for the work at
the rate of $100.00 per hour.

perform all required layout work which shall
include, but will not be limited to the
following:
(1) Piling locations and cut off elevation.

will be required as advance notice to the
Engineer to provide project control staking.

105.09 Authority and Duties of the Project
Engineer. The Project Engineer has immediate
charge of the administrative and engineering details
of each construction project. The Project Engineer
has the authority to exercise all duties and respon-
sibilities of the Engineer contained in the Contract,
except those specifically retained by the Chief

Engineer. The Project Engineer is the only represent-
ative of the Chief Engineer authorized to sign Con-
tract Modification Orders. The Project Engineer is
responsible for initial decisions relating to Con,
tractor claims for additional compensation or exten-
sion of contract time filed pursuant to subsection
105.17.

105.10 Duties of the Inspector. Inspectors
employed by the Division are authorized to inspect
all work done and materials furnished. This inspec-
tion may extend to all or any part of the work and to
the preparation, fabrication or manufacture of the
materials to be used. The inspector is not authorized
to alter or waive the provisions of the Contract. The
inspector is not authorized to issue instructions
contrary to the provisions of the Contract or to act as
foreman for the Contractor.

105.11 Inspection and Testing of Work. All
materials and each part or detail of the work shall be
subject to inspection by the Engineer. The Engineer
shall be allowed access to all parts of the work and
shall be furnished with information and assistance
by the Contractor as required to make a complete and
detailed inspection.
Before final acceptance of the work, the Con-
tractor, shall remove or uncover such portions of the
finished work, as directed. After examination, by the
Engineer, the Contractor shall restore the work to
the standard required by the Contract. If the work
thus exposed or examined prove acceptable, the
uncovering, removing, or restoring the work will be
paid for as extra work. If the work exposed or
examined proves unacceptable, the uncovering, re-
moving, or restoring the work shall be at the Con-
tractor's expense.
Any work done or materials used without super-
vision or inspection by an authorized Division repre-
sentative may be ordered uncovered, removed, or
restored at the Contractor's expense unless the
Division representative failed to inspect the work
after having been given notice in writing that the
work was to be performed.
When any unit of government or political subdivi,
sion, utility or railroad corporation is to pay a portion
of the cost of the work covered by a highway
Contract, its respective representatives shall have
the right to inspect the work. This inspection shall
not make any unit of government or political subdivi-
sion, utility or railroad corporation a party to the
Contract, and shall not interfere with the rights of
either party.
All inspections and all tests conducted by the
Division are for the convenience and benefit of the
Division. These inspections and tests do not con-
stitute acceptance of the materials or work tested or
inspected, and the Division may reject or accept any
work or materials at any time prior to the inspection
pursuant to subsection 105.16(b) whether or not
