DEVELOPMENTAL SPECIFICATIONS
FOR
FLOATING SILT CURTAIN
Effective Date
October 17, 2023
THE STANDARD SPECIFICATIONS, SERIES 2023, ARE AMENDED BY THE FOLLOWING
MODIFICATIONS AND ADDITIONS. THESE ARE DEVELOPMENTAL SPECIFICATIONS AND THEY
PREVAIL OVER THOSE PUBLISHED IN THE STANDARD SPECIFICATIONS.
23011.01 DESCRIPTION.
Floating Silt Curtains are temporary control measures used for containing suspended sediment in an area
of open water. Open water is described as any perennial water course or water body with 6 inch (150
mm) or greater depth. Floating Silt Curtains consist of fabric fastened to a flotation carrier and weighted
along the bottom edge. Two types of Floating Silt Curtains may be utilized:
A. Floating Silt Curtain (Containment).
Floating Silt Curtain (Containment) is intended to capture all sediment entering the water during
construction activities and the sediment is to be removed with the floating silt curtain upon
completion of the work.
B. Floating Silt Curtain (Hanging).
Floating Silt Curtain (Hanging) is intended to create a static water area isolated from the water
course or water body. Sediment entering the static water area is isolated and settles out of
suspension within the area of the floating silt curtain.
23011.02 MATERIALS.
A. Floating Silt Curtains shall meet the following minimum requirements and manufacturer
recommendations:
Table DS-23011.02-1: Floating Silt Curtain Requirements
Property Value
Curtain Fabric Material Type Impermeable vinyl-coated nylon
Mass Per Square Yard 22 oz.
Grab Tensile Strength ASTM D 4632 * 500 lbs.
Flotation 8 inch diameter marine quality
expanded polystyrene
Net Buoyancy, Per Foot 20 lbs.
Top Load Carrying Components
Fabric plus 5/16 inch galvanized
steel cable 9100 lbs. minimum
break strength
Ballast, Lbs. Per Foot, Minimum 1.0 lbs./foot enclosed 5/16 inch
galvanized chain
Connection Between Sections Aluminum collar reinforced quick
disconnects
* Minimum average roll value.
DS-23011, Page 2 of 3
B. Design connecting devices to prevent silt from permeating through the connection and at
specified strength to prevent ripping out.
23011.03 CONSTRUCTION.
A. General.
1. Construct Floating Silt Curtain as shown in the contract documents and to the expected water
depth plus wave height.
2. On US Coast Guard regulated waters or other navigable waterways, furnish buoys to mark
the ends and special areas for visibility. Place buoys as required for navigational purposes.
3. Floating Silt Curtain shall be installed adjacent to planned work area prior to soil disturbance.
The curtain shall be installed along the complete work area which is planned to be disturbed
and to points 20 feet beyond the limits of the area of disturbance and tied into the existing soil
bank.
4. Floating Silt Curtain (Containment) installations will require both a containment floating silt
curtain and a hanging floating silt curtain. Install the two floating silt curtains as shown in the
contract documents with the containment silt curtain closest to shore and the hanging silt
curtain 10 feet outside the containment silt curtain.
5. Do not discharge water pumped from the work site into an area of unrestrained open water.
6. Control surface drainage prior to entry into the water by installation of appropriate erosion
control measures on land.
B. Floating Silt Curtain (Containment).
1. Install Floating Silt Curtain (hanging) prior to installation of Floating Silt curtain (Containment).
2. Shape water body soil bank to enable installation of Floating Silt Curtain (Containment) as
detailed in the contract documents.
3. Install Floating Silt Curtain (Containment).
4. Anchors shall include a chain having a minimum weight of 3.0 pounds per yard and anchor
weights as needed to hold curtain down.
5. Inspect the containment floating silt curtain after heavy winds or major rain storms (1 inch) to
check for damage and depth of silt on the bottom of the silt curtain. If 2 inches or more of silt
is present on top of the silt curtain, remove the silt curtain and silt as described below and
reinstall floating silt curtain.
6. Upon completion of the work or when clean-out of containment silt curtain is required, remove
containment silt curtain. Dispose of collected silt offsite at an upland, non-wetland location or
as approved by the Engineer. Following removal of containment curtain, the hanging curtain
shall remain in place for a minimum of 48 hours after which it can be removed, provided all
work in the area being protected is completed.
C. Floating Silt Curtain (Hanging).
1. Anchors shall be a minimum of 60 pounds and located at a maximum spacing of 50 feet
along curtain.
DS-23011, Page 3 of 3
2. Hanging silt curtain shall remain in place for a minimum of 48 hours after completion of work
activity to allow suspended sediment to settle out after which time the silt curtain can be
removed. Remove curtain in a manner that will prevent re-suspension of silt into the water.
23011.04 METHOD OF MEASUREMENT.
A. Floating Silt Curtain, of the type specified, will be measured by length in feet furnished and
installed.
B. Clean-out of Floating Silt Curtain (Containment) will be measured by length in feet removed,
cleaned, and reinstalled (if necessary) each time cleaning is required.
C. Maintenance of Floating Silt Curtain, when directed by the Engineer, will be measured in feet for
sections of curtain requiring maintenance (typically 50 foot sections).
23011.05 BASIS OF PAYMENT.
A. Payment for Floating Silt Curtain (Hanging) will be the contract unit price for the length in feet of
hanging silt curtain furnished and installed. Payment is full compensation for labor, equipment,
and materials necessary to construct, and remove hanging silt curtain. Upon satisfactory
installation of hanging silt curtain, the Engineer may authorize partial payment not exceeding 80%
of the quantity placed. Remaining quantity will be paid after Floating Silt Curtain is removed.
B. Payment for Floating Silt Curtain (Containment) will be the contract unit price for the length in feet
of containment silt curtain furnished and installed. Payment is full compensation for labor,
equipment, and materials necessary to construct containment silt curtain.
C. Payment for Clean-out of Floating Silt Curtain (Containment) will be the contract unit price for the
length in feet of the Containment Silt Curtain removed each time cleaning is required. Payment is
full compensation for labor and equipment necessary to remove and clean containment silt
curtain, remove and dispose of collected silt, and reinstall containment silt curtain (if necessary).
Clean-out of Floating Silt Curtain (Containment) will be paid to remove the containment silt curtain
at the completion of the project.
D. Payment for Maintenance of Floating Silt Curtain will be at the contract unit price per foot of
floating silt curtain requiring maintenance, as directed by the Engineer. Payment is full
compensation for labor, equipment, and materials necessary to maintain Floating Silt Curtain
(Hanging and Containment). Maintenance includes repairs and realignment of existing curtain
and labor cost when the Floating Silt Curtain is replaced due to loss or destruction. When Floating
Silt Curtain is lost or destroyed, Contactor will receive additional payment based on the material
invoice cost of the replacement curtain.

23032.01 DESCRIPTION.
A. This work shall consist of providing electronic material tickets for all loads of flexible paving
mixture or ready mixed PCC delivered to the project. Electronic ticketing will only be required for
the primary material supplied to the project, i.e. flexible paving mixture for an HMA resurfacing
project or PCC for a PCC paving project. Electronic tickets for other materials supplied to a
project may be submitted at the Contractor’s option. The Contractor/supplier can use the plant
ticketing system of their choice to create the material ticket data.
B. Ticket data shall include the following:
1. After each truck is loaded, ticket data must be electronically captured, and ticket information
uploaded via web service / Application Programming Interface (API) to the agency.
2. Material ticket data will be submitted to https://iowa.dot-portal.io via an HTTPS POST as
JSON documents. Include the API key specific to each customer in each request as an HTTP
header.
3. Material supplier must test to confirm that ticketing data can be shared from the originating
system no less than 30 days prior to project start. Topic shall be discussed at the pre-
construction meeting.
4. Ticket data must be available immediately upon project start so there are no delays to
viewing tickets.
5. Provide the same data that is currently accessible and viewed by agency users previously on
printed tickets specific to state projects.
6. Transmit ticket data before the truck leaves the plant and transmit any updates to the ticket
data within 5 minutes of a change.
