GRADING OPERATIONS Water for Embankment is estimated at the rate of 10 gallons of water per cubic yard of Embankment minus Waste. The estimated cubic yards of excavation and/or embankment required to construct outlet ditches, side streets, and driveways are included in the earthwork balance notes on the profile sheets. Special ditch grades and other sections of the roadway different than the typical section(s) shall be constructed to the limits shown on the cross sections. If significant changes to the cross sections are necessary during construction, the Engineer shall contact the Designer for the proposed change. Generally, all shallow inlet and outlet ditches as noted on the plan sheets shall be cut with a 40-foot wide bottom with 5:1 backslopes. However, the Engineer may direct the Contractor to adjust the ditch width for proper alignment with the downstream drainage. A copy of the soils profile is available for review at the Rapid City Region and Rapid City Area offices. Temporary fence and/or permanent fence shall be placed ahead of the grading operation unless directed by the Engineer.

STREET SWEEPING Vehicle tracking of sediment from the construction site shall be minimized. Street sweeping shall be used if erosion and sediment control best management practices are not adequate to prevent sediment from being tracked onto the street. The Contractor shall use a pickup broom having integral self-contained storage to clean the roadway. The pickup broom used shall be a minimum of 6 feet wide and have working gutter brooms. At a minimum, sweeping will be required: 1. Prior to opening any segment or roadway to traffic. 2. Following pavement grooving operations and prior to the application of

the pavement marking tape. 3. When sawing operations are underway in the inside driving lanes, the

outside driving lanes and gutter may need to be swept to control dust. 4. Whenever sediment is tracked onto the roadway being used by traffic. All costs for cleaning the roadway with a pickup broom shall be incidental to the contract unit price per hour for “Sweeping”.

DEWATERING AND SEDIMENT COLLECTING The Contractor has the option to treat sediment laden water trapped within the project limits with the DEWATERING AND SEDIMENT COLLECTION SYSTEM as described in the detail drawings, or the Contractor may elect to transport sediment laden water off the project. Water transported off the project limits shall not be disposed of in an area where it can enter a waterway. The disposal site must be approved by the Engineer. CONSTRUCTION ENTRANCE The Contractor shall install a Construction Entrance at locations where there is a potential for mud tracking and sediment flow from the construction site and work area onto a paved public roadway. It is the Contractor’s option to use the SDDOT Construction Entrance (See SDDOT Construction Entrance notes and details), a product from the list provided in these notes, or other products or processes as approved by the Engineer during construction. If the Contractor elects to use one of the products listed in the table, then the Contractor shall install the construction entrance product in accordance with the manufacturer’s installation instructions or as directed by the Engineer. The Contractor shall maintain the construction entrance such that mud tracking and sediment flow will not enter the roadway or adjacent drainage areas. The construction entrance shall be routinely inspected and the Contractor shall repair or replace material as deemed necessary by the Engineer. All costs for furnishing, installing, maintaining, and removal of the construction entrance including equipment, labor, materials, and incidentals shall be included in the contract unit price per each for “Construction Entrance”.

The granular material shall be placed in 6” maximum lifts. It is anticipated that the granular material will need to be periodically removed and replaced as it becomes inundated with mud and sediment. The reinforcement fabric (MSE) shall conform to Section 831 of the Specifications. The MSE geotextile shall be on the Approved Products List for this material or will be certified by the supplier to meet this specification prior to installation. The reinforcement fabric (MSE) should be kept as taut as possible prior to placing. Equipment shall not be allowed on the reinforcement fabric (MSE) until the first lift of granular material is in place. All seams in the reinforcement fabric (MSE) shall be overlapped at least 2’ and shingled.

FOOTING DATA

The subsurface conditions from the beginning of the project to approximately station 42+00 consist of reddish brown silt-clay up to 5’ in depth overlying red sandy clay-silt (Spearfish Formation) to 15’ below the surface. Occasional gypsum layers up to 1.5’ thick were encountered at various depths throughout this section of the project. No groundwater was encountered during the investigation in this section of the project. The borings caved between 11.9’ and 13.3’ below the surface.
