B. All existing drainage facilities including, but not limited to: brooks, streams, canals,
channels, ditches, culverts, catch basins and drainage piping shall be adequately
safeguarded so as not to impede drainage or to cause siltation of downstream areas in
any manner whatsoever. If the Contractor damages or impairs any of the aforesaid
drainage facilities, he shall repair the same within the same day.
C. At the conclusion of the work, the Contractor shall remove all silt in drainage
structures caused by his operations.
8. Rejected Materials and Defective Work
A. Materials furnished by the Contractor and condemned by the Engineer as unsuitable
or not in conformity with the specifications shall forthwith be removed from the
work by the Contractor, and shall not be made use of elsewhere in the work.
B. Any errors, defects or omissions in the execution of the work or in the materials
furnished by the Contractor, even though they may have been passed or overlooked
or have appeared after the completion of the work, discovered at any time before the
final payment is made hereunder, shall be forthwith rectified and made good by and
at the expense of the Contractor and in a manner satisfactory to the Engineer.
C. The Contractor shall reimburse the Owner for any expense, losses or damages
incurred in consequence of any defect, error, omission or act of the Contractor or his
employees, as determined by the Engineer, occurring previous to the final payment.
9. Sanitary Regulations
Sanitary conveniences for the use of all persons employed on the work, properly screened
from public observation, shall be provided in sufficient numbers in such manner and at
such locations as may be approved. The contents shall be removed and disposed of in a
satisfactory manner, as the occasion requires. The Contractor shall rigorously prohibit the
committing of nuisances within, on or about the work. Any employees found violating
these provisions shall be discharged and not again employed on the work without the
written consent of the Engineer. The sanitary conveniences specified above shall be the
obligation and responsibility of the Contractor. They shall not be located on private
property unless written authorization from the property owner has been provided to the
Engineer.
10. Site Investigation
The Contractor shall be responsible for verifying and determining the location, size,
direction of flow (if applicable) and elevation of all existing utilities, shown or not shown
on the plans. Every effort has been made to accurately depict the existing sewer system,
including sewer services. However, due to the age of the system, there are no records for
some sewer services as indicated on the plan set. These situations, including other
unknown pipes encountered during excavation, may require additional investigations. The
City may avail staff and equipment to aid in the investigation. Considerations for delay
costs shall only be given in extreme circumstances.
