When fertilizer ratios other than those shown above are used, the relationship between the pay quantity and the actual quantity used will be established by the Engineer. Silt fence will be measured by the linear foot at the bottom of the fence, excluding laps. Decomposed or ineffective fabric in the silt fence which is required to be replaced after six months from the installation date will be measured and paid for, however, such replacement prior to six months after installation will not be measured for payment. In the event that temporary er osion and pollution control measures are required due to the Contractor's negligence, carelessness, or failure to install permanent controls as a part of the work as scheduled, or as ordered by the Engineer, such work shall be performed by the Contractor a t their own expense. Temporary erosion and pollution control work required, which is not attributed to the Contractor's negligence, carelessness or failure to install permanent controls, shall be performed as ordered by the Engineer. Where the work to be performed is not attributed to the Contractor's negligence, carelessness or failure to install permanent controls and falls within the Specifications for a work item that has a contract price, the units of work will be paid for at the proper contract pric e. Should the work not be comparable to the project work under the applicable contract items, the Contractor shall perform the work in accordance with 104.3. In case of repeated failure on the part of the Contractor to control erosion, pollution, or siltation, the Engineer reserves the right to employ outside assistance or to use their own forces to provide the necessary corrective measures. Such incurred direct costs plus project engineering costs will be charged to the Contractor and appropriate deduct ions made from the Contractor's monthly progress estimate. Temporary pollution control may include construction work outside the right -of-way where such work is necessary as a result of roadway construction such as borrow pit and waste site operations, ha ul roads and equipment storage sites. Super Silt Fence will be measured by the linear foot complete and in place. 642.7.1 -Temporary Pollution Control, Unit’s Value Method: For “Temporary Pollution Control” for which a number of units are established i n the contract, will be measured by each temporary pollution control device used and accepted. Unless listed elsewhere within the Contract Documents, the relative value of each temporary pollution control device shall be calculated from the table poste d at: https://transportation.wv.gov/highways/TechnicalSupport/specifications/642.7UnitValueMet hod/Pages/default.aspx . The total units of temporary pollution control shown in the Contract is an estimated amount only and may be adjusted up or down by the Engineer in accordance with the project needs. 642.8 -BASIS OF PAYMENT : Except where provided for elsewhere in these specifications, the quantities determined as provided above, will be paid at the contract unit prices bid for the items listed below, which prices 566 and payment shall be full compensation for furnishing all materials and doing all the work prescribed in a workmanlike and acceptable manner, including all labor, tools, equipment, supplies, and incidentals necessary to complete the work, including necessary maintenance, and removal where applicable. 642.9 -PAY ITEMS : ITEM DESCRIPTION UNIT 642000 -* Temporary Pollution Control Unit 642001 -* Temporary Berm Linear Foot 642002 -* Slope Drain Linear Foot 642004 -* Seed Mixture, “type” Pound 642005 -* Mulch, “type” Ton 642006 -* Fertilizer Ton 642007 -* Fiber Matting Square Yard 642008 -* Temporary Pipe Linear Foot 642009 -* Contour Ditch Linear Foot 642010 -* Agricultural Limestone Ton 642012 -* Silt Fence Linear Foot 642015 -* Super Silt Fence Linear Foot 642031 -* Rock Check Dam Each 642033 -* Sediment Trap Cubic Yard 642034 -* Sediment Basin Cubic Yard 642035 -* Riser Each 642036 -* Sediment Removal Cubic Yard 642040 -* Inlet Protection Each 642050 -* Dewatering Device Each *Sequence number SECTION 643 THROUGH SECTION 644-BLANK
