- 149 - SECTION 208 -- BORROW AND WASTE SITE RESTORATION
208.01 Description
1.This work consists of the rest oration of Department provided sites from which borrow is obtained or where waste soil materials are disposed.
208.02 Construction Methods
1.The Contractor shall begin t he restoration work, including the seeding, as soon as all borrow material has been removed or all wasted soils are disposed and finish graded.
2.The Contractor shall scarify t he entire area, including slopes, to a minimum depth of 6 inches (150 mm).
3.The Contractor shall remove the available topsoil at State-furnished borrow sites and waste sites to a minimum depth of 6 inches and stockpile this material in approved areas. The Contractor shall uniformly spread topsoil that was stockpiled at the st art of excavation over the area. The entire area, including the stockpile areas, shall be seeded in accordance with Section 811 using the kinds and rate s specified in the special provisions for borrow/waste site restoration.
4.The Contractor shall adjust se eding time as outlined in Section 811 to fit conditions prevailing on the project.
5.The Contractor shall leave borrow and waste sites in a neat and presentable condition, in accordance wi th any land contract requirements, and acceptable to the Department upon completion of the work.
208.03 Method of Measurement
1."Restore Borrow Site" and "Restore Waste Site" will be surface measured, and the unit of payment will be the acre (hectare) of site area actually used. The area of borrow sites and waste sites restored shall be the quantity shown in the contract unless changes are authorized.
2.All temporary stockpile areas sha ll be considered subsidiary to the work of "Restore Borrow Site " or "Restore Waste Site".
208.04 Basis of Payment
1.Pay Item Pay Unit Restore Borrow Site Acre (A) [Hectare (ha)] Restore Waste Site Acre (A) [Hectare (ha)]
2.Payment is full compensation for all work described in this Section. - 150 - SECTION 209 -- OVERHAUL
209.01 Description
1.All excavated materials shall be hauled as shown in the contract from the source locations to the deposit locations and, regardless of the haul distance, overhaul will not be considered.
2.Overhaul will not be considered for material hauled from sites that are not shown in the contract (i.e. cont ractor obtained sites due to the item of Excavation, Borrow) or fr om sites substituted by the Contractor for the convenience of his/her operation.
3.When field conditions differ from the contract causing an increase in the haul distance, overhaul compensation will be allowed if all six of the following conditions are met:
a.The available excavation, within the affected balance, is inadequate to construct the embank ment within that balance.
b.All available excavation, within the affected balance, has been incorporated into the embankment within that balance.
c.The contract has not provided Excavation, Borrow for embankment construction in the affected balance.
d.The materials must be obtained from outside the affected balance or from Borrow Sites not shown in the contact.
e.The actual haul distance is greater than the av erage plan haul distance (also known as the "free haul distance") for the affected balance.
f.The actual haul distance is greater than the minimum free haul distance of 1,500 feet (457 m).
209.02 Method of Measurement
1.The length of overhaul shall be determined by computing the centers of volume of the overhaul materi al in its original position and after placement. The centers of volume sha ll be determined by computation. The distance between the centers of volu me minus the average plan haul distance or minimum free haul distance whichever is greater shall be the overhaul distance.
2.The quantity of overhaul shall be measured in CY/Sta (m3/Sta M) and shall be the product of the overhaul distance in stations of 100 feet (100 m) multiplied by the volume of mate rial in cubic yards (cubic meters).
3.The average plan haul dist ance will be determined from the Earthwork Data Sheets contained in the contract.
209.03 Basis of Payment
1.Pay Item Pay Unit Overhaul Cubic Yard/Station (CY/Sta) [ C u b i c M e t e r / S t a t i o n ( m3/Sta M)]
2.Payment for overhaul shall be made at the rate of $0.06/CY/Sta. ($0.27/m3/Sta M).
3.Payment is full compensation fo r all requirements described in this Section.
