SPECIAL PROVISIONS
Project No. C-28(492)
This project is governed by the General Requirements and Covenants of the Douglas County
Standard Specifications for Highway Construction, 2000, as may be modified by these Special
Provisions.
The Construction Details shall be as specified by the City of Omaha Standard Specifications for
Public Works Construction, 2003 and latest supplements thereto, the attached Supplemental
Specifications and these Special Provisions.
PRE-CONSTRUCTION MEETING
As soon as practical after award of contract, but prior to beginning work on this project, the
contractor shall attend a pre-construction meeting unless the requirement for such meeting is waived
by the County Engineer.
The purpose of this meeting shall be the specific planning of how the work is to be accomplished,
which shall include but not be limited to a written time schedule for the closing to traffic of any
streets or roads, utility work, access to properties and major items of work required by the plans such
as grading or paving.
LIQUIDATED DAMAGES
Time is of the essence for the faithful and timely performance of the terms of the Contract. The
parties hereto agree that it is not possible to predetermine an amount in actual damages due Douglas
County whenever timely completion is not accomplished; therefore, in lieu of actual damages, the
parties to this Contract agree, as per Subsection 108.07 of the Douglas County Standard
Specifications for Highway Construction, Liquidated Damages shall be charged at a rate of One
Thousand Dollars, $1,000.00 per calendar day for each day that the construction of this project
extends beyond the number of calendar days as specified in the Contract with any additional days
granted by the engineer, provided that full safe use of the newly constructed phase of the facility is
denied the public.
BARRICADES, DANGER, WARNING AND DETOUR SIGNS
1. All barricades, warning signs, lights, temporary signals and other protective devices must
conform with the latest edition of the Manual of Uniform Traffic Control Devices for Streets and
Highways published by the U. S. Government Printing Office. All barricades and signs shall be
constructed and erected in accordance with the plans furnished.
2. The contractor shall provide, erect and maintain all necessary barricades, suitable and sufficient
lights, hazard beacons, other signs, provide a sufficient number of watchmen and take all necessary
precautions for the protection of the work and the safety of the public. All lights shall be kept
burning from sunset to sunrise.
3. The contractor shall erect warning signs in advance of any place within the project limits where
operations interfere with the use of the road by traffic, and at all intermediate points where the new
work crosses or coincides with an existing road. Such warning signs shall be constructed and
erected in accordance with the plans furnished.
SP - 2

SPECIAL PROVISIONS
Project No. C-28(492)
4. Failure of the contractor to erect and maintain traffic protective devices as herein specified shall
be reason to temporarily suspend the work in accordance with Subsection 105.01.
The contractor shall be given notice, either written or verbal, of failure to install, replace, remove, or
maintain a traffic protective device. If corrective action is not taken within four hours, a written
notice shall be given to the person designated for work zone traffic control. The contractor's office
shall also receive a copy of such notice; facsimile transmission shall be used if possible.
If corrective action is not taken within four hours of the initial notice, the project manager may elect
to make no payment for the device for that day. Failure to install, replace, remove, or maintain a
device within eight hours of the initial notice may result in no payment being made for any traffic
protective devices on the project for that day and on subsequent days until the requested installation,
replacement, removal, or maintenance is performed.
5. The County shall erect and maintain detour signs in advance of the project limits.
Application Details
A. Hazard identification beacons and flashing or steady-burning lights shall be
used to warn the motorist of hazards associated with the construction project. The
engineer may require the use of additional beacons or lights, if, in his judgment, more
protection is needed than might normally be considered adequate.
B. Each light shall be checked and serviced with sufficient frequency to insure
that lights are always operating with the brightness available with fresh batteries and
new lamps. The lenses shall at all times be clean, free of mud or dust film.
C. The contractor whose work requires the control and protection of traffic in
accordance with the applicable sections of these specifications, shall furnish signs, all
materials including necessary posts, bolts or other fasteners, erect and maintain all
signs, barricades and other traffic control devices in accordance with the details, and
at the locations shown in the plans. When more than one contractor is working on the
project and both require the protection and control of traffic, the engineer shall
determine and notify in writing the contractor whose responsibility it shall be to
provide the protection and control of traffic. The responsibility may vary from time
to time, depending upon the operation in progress, and there shall be no duplication of
protective and control devices at the same location.
D. The signs shall be placed at the time construction work begins in compliance
with the applicable conditions of the Standard Plan(s) and shall be so used until
permission is granted, in writing, by the engineer that the work is completed or
temporarily suspended, and that they may be removed.
Measurement and Payment
A. Type III barricades shall be measured for payment by the number of calendar
days each Type III barricade is in place and positioned as shown on the plans or as
directed by the engineer. Payment shall be made at the contract unit price per
barricade day for the item "Barricade and Warning Signs." This price shall be for all
SP - 3

SPECIAL PROVISIONS
Project No. C-28(492)
labor, equipment, tools and incidentals required to place the Type III barricade. The
minimum length of a Type III barricade shall be eight (8) feet.
B. The furnishing, erecting and maintaining of all other traffic control and
protection devices shown on the plans or as ordered by the engineer shall not be
measured and paid for directly, but they shall be considered subsidiary to the items
for which the contract provides that direct payment will be made.
CONTRACT START DATE
Work under this contract will begin on or about August 26, 2013. Contractor’s request for an earlier
start date will be considered. The contract days for this project will be strictly enforced.
CONTRACT PAYMENT
Payment for work under this contract will be made for only those items listed in the proposal. The
cost of all other work, materials and miscellaneous items necessary to construct this project in
accordance with the plans and specifications, shall be considered incidental to the unit bid prices of
the items listed in the proposals.
NPDES PERMIT
This project has been authorized to discharge storm water under NPDES General Permit
NER110000. The authorization number is NER113798. The contractor is responsible for
compliance with the terms and conditions of this permit and the Storm Water Pollution Prevention
Plan (SWPPP) which are housed at the Douglas County Engineer’s Office and available for review
upon request.
STATUS OF UTILITIES
At this point, all known utility companies in the area have been contacted and are shown on the
plans for the convenience of the contractor. It is the responsibility of the contractor to properly
locate all utilities in the field, both shown and not shown in the plans. Below is a list of known local
utilities and their current status:
Omaha Public Power District
OPPD has reviewed the 90% plans for the project listed above. There is a three phase overhead
line on the south side in conflict and will be relocated to new right of way.
OPPD has notified Douglas County that the conflicting poles will be relocated concurrently with the
project and after removal of the trees on the south side of Fort Street.
Contact: Joe Ostblom - (402) 636-3513
CenturyLink
CenturyLink has a 9 way duct structure running east and west on the south side of Fort Street. This
is running around 22' to 24' Rt and will need to be moved /adjusted for the grade cuts in this area.
At first glance I would like to lower this in place concurrently with the project, if the general
contractor would remove grade from the northside first then allow our contractor to move in to drop
SP - 4

SPECIAL PROVISIONS
Project No. C-28(492)
the duct to its new elevation. The time it would take depends on the material of the ductline. I won't
have that confirmed until the potholing is completed.
