230 Page 144230 SALVAGING, STOCKPILING, AND PLACING TOPSOIL
230.1DESCRIPTION
This work consists of excavating, hauling, stockpiling, depositing, and spreading topsoil on prepared areas.
230.2MATERIALS (Not specified)
230.3CONSTRUCTION REQUIREMENTS
A.Salvage: Topsoil will be selected from the regular grading areas or from other designated areas. Areas from which topsoil is to be excavated will be cleared of objectionable vegetation and all litter such as brush, rock, and foreign material. Topsoil will be excavated in sufficient volume to cover the designated areas to the required depths. Salvaged topsoil may be stockpiled in convenient locations within the right-of-way as approved by the Engineer. The separation of cut and fill piles is not required. Topsoil piles will be located where the topsoil will not run off into any waterway due to a rain event. When operations of the Contractor do not permit stockpiling of topsoil within the right-of-way, it will be the Contractor's obligation to arrange for stockpile sites at the Contractor’s own expense. The stockpiles will be shaped and smoothed to permit accurate measurements. Stockpile areas will be left in a neat condition. B.Preparation of Roadway: Areas designated to be covered with salvaged topsoil will be undercut or underfilled, so the finished lines conform to the template lines on the cross sections after the topsoil placement. The areas receiving topsoil will be shaped and smoothed prior to placing topsoil. C.Placing: Topsoil will be spread evenly and uniformly over the designated areas to the specified depth. If topsoil is not available in sufficient quantities to cover the designated areas to the plan specified depth, the Contractor will spread the available topsoil as required by the Engineer.
230.4METHOD OF MEASUREMENT
A.Salvaged Topsoil: Measurement for removal of topsoil from its original position will be made in cubic yards. Measurement will not be made unless such removal is designated on the plans or directed by the Engineer. The volume of topsoil will be determined by measuring the topsoil stockpiles. B.Placing Topsoil: The cubic yards of topsoil to be measured will be the quantity of topsoil removed from stockpiles and placed on the designated areas. Measurements will be made prior to removal of the material from such stockpiles. 230 Page 145230.5 BASIS OF PAYMENT A.Salvaged Topsoil: Topsoil salvaged from Contractor furnished borrow sources will be incidental to the contract unit price per cubic yard for contractor furnished borrow excavation. Topsoil salvaged from option borrow sources will be paid for at the contract unit price per cubic yard for option borrow excavation. Topsoil salvaged from designated borrow sources will be paid for at the contract unit price per cubic yard for borrow unclassified excavation. All other topsoil will be paid for at the contract unit price per cubic yard for unclassified excavation. The amount of topsoil that has been added to the option borrow excavation, borrow unclassified excavation, and unclassified excavation quantity will be indicated on the plans. The payment will be full compensation for excavation (which includes necessary undercutting to provide space for topsoil placement) and stockpiling. Separate payment will not be made for haul under this item. B.Placing Topsoil: The placement of salvaged topsoil will be paid for at the contract unit price per cubic yard for placing topsoil. Topsoil placed on Contractor furnished borrow sources will be incidental to the contract unit price per cubic yard for contractor furnished borrow excavation. This payment will be full compensation for labor, equipment, tools, and incidentals necessary for removing topsoil from stockpiles, hauling, depositing, spreading, and finishing of topsoil. Separate payment will not be made for haul under this item. 240 Page 146240 OBLITERATING OLD ROADS
240.1DESCRIPTION
This work consists of scarifying, plowing, grading, and harrowing of abandoned roads outside the limits of the new construction.
240.2MATERIALS (Not Specified)
240.3CONSTRUCTION REQUIREMENTS
After opening the new road to traffic the portion of the road to be obliterated will be graded to a contour which will blend with the contour of the adjoining land. Obliteration and removal will include flattening the backslopes and embankment slopes so farm cultivation work could be done to the satisfaction of the Engineer. Portions of the obliterated road surface to be covered with less than 1 foot of earth will be scarified to a depth of not less than 6 inches. In areas of rock or rough topography not adaptable to cultivation, the desired obliteration and disposal will be detailed on the plans.
240.4METHOD OF MEASUREMENT
The item of obliterating old roads will be measured to the nearest station of 100 feet along the centerline of the old road.
240.5BASIS OF PAYMENT
Payment for obliterating old roads will be made at the contract unit price per station inclusive of all labor and equipment required.
