The CONTRACTOR shall construct temporary sediment traps with granular outlets within the disturbed roadway area and shall stockpile a sufficient quantity of suitable fill material to regrade sedimentation ponds and temporary ditches to match the subgrade elevation. Mn/DOT is requesting that machine sliced silt fence be used as the standard method of installation. The heavy duty type silt fence shall be used only in atypical situations where the machine sliced cannot be used. The reason the silt fence, Type Heavy Duty, is included in the City of Shako pee DIV2 General Specifications and Standard Detail Plates for Page 19 of 25 Street & Utility Construction bid proposal is to make allowance for possible wet areas where the machine may not be able to operate efficiently. Purpose: The purpose of this special provision is to provide criteria for the proper installation of machine sliced silt fence. The silt fence must be installed properly with proper equipment or function of the silt fence will be compromised. Background: Mn/DOT has recently approved the use of silt fence installed by machine that slices the ground and inserts the geotextile into undisturbed soil. The sliced in method is often desirable in that no wire mesh is used and silt fence is uniformly and firmly embedded into the ground. Guidelines: To insure proper function, the machine sliced silt fence shall be installed in accordance with the attached detail drawings. These detail drawings were extracted from Standard Plan Sheet 5- 297.405. The bottom of the geotextile shall be installed with an approximate 6-inch cuff and into the soil a minimum of 8 inches. In a ditch check installation, a 5/8-inch minimum diameter rope shall be inserted into the 6-inch cuff. Approved Equipment: The equipment approved to install the sliced in silt fence shall have a single vertical shank approximately 1 inch thick by 18 inches min. length that when inserted into the ground makes a thin slice 8-12" deep. The lower part of the shank shall have an approximate 2" diameter chisel type horizontal point that shears through the soil with minimal soil displacement. Mounted directly behind the vertical shank is a ground driven vertical wheel that cuffs the geotextile and inserts it into the soil slit caused by the vertical shank. As the machine is pulled along the vertical shank makes an approximate 1-inch wide vertical slit 8 to 12 inches deep. The bottom edge of the geotextile is folded with an approximated 6-inch cuff and inserted into the soil slit all in one operation. In ditch check installations a 5/8" minimum diameter rope shall be inserted into the cuff. The approved installation machine shall be a Devon Distributing Corporation Tommy silt fence machine or approved equal. Machines that turn the soil over, do not properly cuff the bottom edge of the geotextile or will not insert the required rope on ditch check installations will not be approved. Compaction: Immediately after the geotextile has been sliced into the soil, the ground shall be compacted by driving the wheels of a tractor or skid loader next to and parallel with the fence on both sides of the fabric. The geotextile shall then be fastened to the support posts. The upstream side shall be compacted first, then each side twice for a total of four passes. In saturated areas covered by surface water, the soil shall be compacted by foot tamping or other approved methods. Inspection: Project personnel must verify that the silt fence is installed in accordance with the silt fence details (attached and Standard Plan Sheet 5-297.405). Project personnel must also verify that City of Shakopee DIV2 General Specifications and Standard Detail Plates for Page 20 of 25 Street & Utility Construction approved equipment is used to slice the silt fence into the soil and that the soil adjacent to the fence is compacted. Because the bottom edge of the silt fence is held inplace by only the friction between the geotextiles and the soil, it is extremely important that all installation details are adhered to. Payment: Payment for sliced in silt fence will be compensation for all labor materials, equipment and other incidentals necessary to complete the work as specified. Compaction of soil along the fence shall be considered incidental to the silt fence installation. Rope insertion on silt fence ditch check installations shall be considered incidental to the ditch check installation. 02573.5 Basis of Payment: Payment for Silt Fence, Type Machine Sliced, and for Silt Fence, Type Heavy Duty, shall be by the linear foot of correctly installed and accepted silt fence of each type actually placed on the project site.
