6. PERCENT OF CONTRACT TO BE PERFORMED BY PRIME CONTRACTOR
The Prime Contractor shall be required to perform at least 20 percent of the total contract amount
of this project. Purchasing of materials for subcontractors will not be an acceptable method for the
prime contractor to meet the 20 percent requirement.
7. INFORMATIONAL SIGNS RELATING TO CONSTRUCTION
A. Advanced Informational Signs
Advanced information signs shall be placed near the beginning and end of the project six
(6) calendar days in advance of the street being closed for construction. These signs shall
be approximately 2' x 3' in size, with the following wording: "This street to be closed for
construction on (day of the week). One percent local option dollars at work. Thank
you for your cooperation." Signs shall be placed on E. San Marnan Drive. These
informational signs shall be considered incidental to the traffic control bid item.
B. After-Construction Signs
These signs shall be similar as the Advanced Informational Signs, except that the first line
shall read: "This street constructed with Local Option Dollars." After-construction signs
shall be placed on all streets after they have been completed and open to traffic.
The after-construction signs shall remain in place for at least four (4) weeks. The cost of
these signs shall be considered incidental to applicable items.
8. STORM WATER POLLUTION PREVENTION/INLET PROTECTION DEVICE
Storm water pollution prevention has become an important issue on construction projects. Therefore,
the City is requiring that the storm sewer system on this project be protected in order to reduce and
minimize the impact of sediment-laden runoff flowing into the storm sewer system.
Detail sheets are included in the plans with representation of various structures and the proposed
protection to be provided.
Structures that are unlikely to receive storm water during the construction process are not included in
the Estimated Quantity for Inlet Protection Device. Protection will be placed at those locations directed
by the Engineer or his representative.
No separate payment will be made for protection of open ends of storm sewer pipe, but this will be
considered incidental to applicable items.
Should the protection not be provided or not maintained, the contractors will be required to remove
sediment from the inlets or storm sewer at his own expense. The materials shall be removed in such
a manner as to present further contamination of the storm sewer system and subsequent impairment
of downstream receiving waters of the sewer.
