Technical Specification - UNDP

The Engineer may check all or any portion of the stake-out survey work or notes
made by the Contractor and any necessary correction to the Work shall be
immediately made. Such checking by the Engineer shall not relieve the Contractor of
any responsibilities for the accuracy or completeness of his work.
1.12 Survey Monuments
When any monument or property marker, whether of stone, concrete, wood or metal,
or a mark on the pavement or sidewalk designating the lines of the streets or highway
or of private property is in the line of any trench of other constructing work and may
have to be removed, the Contractor shall notify the Engineer in writing at least 48
hours in advance of removal. Under no circumstances shall such monument or marker
be removed or disturbed by the Contractor or by any of his sub-contractors,
employees or agents, without a written order from the Engineer. The Contractor shall
furnish all necessary labor and materials required in correctly resetting any monument
or property maker disturbed. Should nay monument or marker be destroyed through
accident or neglect, the Contractor will be required, at his own expense, to correctly
reestablish the monument or marker.
1.13 Subsurface Structures and All Utilities
Before beginning excavation operations, the Contractor shall contact the specified
departments of the Municipality and utilities and notify them of his intention to begin
excavation operations.
The contractor has to consider all the existing obstacles in his price.
The Drawings may show and specifications may discuss certain drainage or other
structures or facilities believed to exist in the working area, the exact location of
which may vary from the locations indicated. All drainage or other structures or
facilities may not be shown. The Drawings do not show all sewage collection pipes,
storm water collection conduits, underground electric conduits or aboveground
telephone facilities, underground sanity facilities, all of which are known to exist in
the area. There may be certain other facilities and utilities in the work are not listed
above or not shown on the Drawings, including all service connections that must
remain in service.
It shall be the responsibility of the Contractor to determine the exact location of such
pipeline, subsurface, structures and/or utilities ahead of his Work by exploratory
excavation or other means and to take suitable precautions to prevent damage to them
and to prevent interruption of the services which such facilities provide. If they are
broken or damaged, they shall be restored by the Contractor or the appropriate utility
at the Contractor's expense. Where pipelines, subsurface structures and/or utilities
encountered in the Work coincide with the location of the Employers water pipes and
the Engineer deems it advisable, the location of the water pipes may be changed to
avoid the facilities. Where the Engineer does not deem it advisable to relocate the
Employer's water pipes and where the pipeline, subsurface structures and/or utilities
require relocation before the work can proceed, the Contractor shall notify the
Engineer and the owner of said facilities of the location and circumstances and shall
cease Work, if necessary, until the Contractor can establish satisfactory procedures to
