payment estimates and may be used to verify costs of credits, change orders, etc.
1. The tentative schedule of values will be reviewed by the Project Manager to
determine whether, in his judgement, it is s~fffi~iently detailed for the purpose
intended. The Project Manager will also evahate the schedule to dete~mlne
whether, in his judgemeat, the prices included are "unbalancod" or "front-end
loaded" in an'effort to inflate the prices of those items of work to be completed
in the early stages of the work.
2. The Engheer w~l provide the Contractor with his comments and/or may request
additional information from the Contractor to justiTy certain itms, quantities and
prices therefor. On the basis of the Project Manageis comments, the Contractor
shah revise and resubmit the tentative schedule for further review and/or
approval.
Once the tentative schedule is approved by the Project Manager, it shall become
the schedule of values to be used in determining partial payment estimates.
Twenty (20) copies ofthi.g schedule shall be submitted to the Project Manager
for dism'bution and his use.
No partial payment request (including the first) will be approved until the
schedule of values has been approved by the Project Manager.
Include with each partial payment request the approved schedule ofvalues, modified
to indicate the total quantity and price of work completed to the date of the request.
After approval of the submittal, no modifications canl be made to the schedule of
values.
Show total quantities and unit prices for all items of work, separating each item by
materials and hbor and such other sub-items as may be desired. Avoid "b~mp Snm",
"mi-qcellaneous", and other such general entries in the schedule. Such items as Bond
premium,% temporary facilities and equipment storage may be listed separately in the
schedule ofvalues, provided the costs can be substantiate& Do not list overhead and
profit as separate items.

EROSION CONTROL DURING CONSTRUCTION
PART 1
1.01
GENERAL
SCOPE OF WORK
Furnish all the necessary materials, hbor, tools, equipment, and other incidentals
required to design, install, maintain, and remove aRer construction all temporary
erosion control devices shown on the Drawings and specified herein. The purpose
of erosion control is to prevent sediment laden runoff from leaving the construction
area at 'any time. Refer to NTCOG Item 3.12.
1.02
REFERENCED STANDARDS
North Tens Council of Governments (NTCOG) - '~3eneral Specifications For
Public Works Construction".
TYPES OF EROSION CONTROL
Straw Bale Dike
The purpose of a straw bale dike is to intercept and detain small amounts of
sediment laden nmoff from relatively small unprotected areas. This type of system
can only be used in conjunction with other devices, such as a silt fence. It is not a
"stand alone" option.
Silt Fence
A silt fence serves the purpose to intercept and detain water borne sediment from
unprotected areas to a limited extent. Silt fences are the most common means of
erosion control used.
Triangular Sediment Filter Dike
A triangular sediment filter dike intercepts and detains water borne sediment from
unprotected areas of less than one acre. If the uphill slope above the dike ex~eds
10 percent, the length of slope above the dike should not exceed 50 feet without
additional devices uphill. This device is effective on paved areas where instalhtion
of a silt fence is not practical.
Coppert 2 Meter Vault/94-81/2-6-97 02290 - 1
iT l' llll I
EROSION CONTROL DURING
CONSTRUCTION
D. Stabilized Construction Entranc~
The purpose of constructing a temporary stabilized construction entrance is to
prevent sediment from leaving the project site and becoming a nuisance on a paved
street. Install a temporary stabilized construction entrance at any point where traffic
will be entering or leaving' a construction site to a paved surface, thus reducing or
eliminating the tracking or flowing of sediment onto the paved surface.
E. Other Control Devices
Diversion Dike: A temporary diversion dike is a barrier created by the
placement of an earthen embankment to reroute the flow ofnmoffto an
erosion control device or away from an open, easily eroch~le area.
Interceptor Swale: A temporary interceptor swale iS excavated as required to
shorten the length of exposed slope by intercepting runoff They can also
serve as perimeter swales preventing off-site nmofffrom entering the
disturbed area or prevent sediment laden runoff from leaving the construction
site or disturbed area.
