201.1 Description
Clear and grub the vegetation and debris as specified in the Contract Documents. DO NOT clear and grub areas unless work will actively be performed in the exposed area (or portions of the exposed area) within 7 calendar days on exposed steep slope areas (40% or greater) or within 14 calendar days for all other exposed areas. B I D I T E M U N I T S Clearing and Grubbing Lump Sum
201.2 Materials
Backfill stump holes using granular material or loose friable soil from the project. Use material that is free of excess moisture, frozen lumps, roots, sod, rocks greater than 4 inches in diameter or other deleterious material. The Engineer will accept th e backfill material based on visual inspection.
201.3 Construction Requirements
Do not damage any vegetation designated to remain. The Engineer will identify any trees, shrubs and other vegetation designated to remain. Remove low ha nging, unsound or unsightly branches on trees and shrubs designated to remain as specified in the Contract Documents. Trim the br anches according to recognized industry practices. Within the construction limits, clear and grub all vege tation not designated to remain. Undisturbed stumps and roots no more than 6 inches above the original ground line or low water level may remain, provided they are a minimum of 3 feet below the finished subgrade or embankment slope and approved by the Engineer. Strip and stockpile the existing topsoil from within the construction limits. To the extent practical, use this material to cap the finished embankment and cut slopes. This work is subsidiary to grading items in the contract. Where practical, do not store equipment or materials (including soil stockpiles) within 50 feet of rivers, streams or other surface waters. Where such storage is necessary, obtain the Engi neer’s written approval and include in the project SWPPP appropriate best management practices for the storage area. Unless requested in writing from the Contractor, and approved in writing by the Engineer, or specified otherwise in the Contract Documents, do not exceed 750,000 square feet of su rface area of erodible earth material per equipment spread at one time. The Engineer will limit the surface area of erodible earth material exposed by clearing and grubbing, excavation, borrow (within right-o f-way) and embankment operations. Limit the exposed erodible earth material according to the capability and progress, and in keeping with the approved schedule. Areas will not count toward the 750,000 square feet limit, when the following conditions are met: For areas that will not be disturbed again due to project phasing: Finish grade the completed area; Stabilize and maintain stabilization according to SECTION 902; and Do not disturb the area again without a written request from the Contract or and written approval from the Engineer; For areas that will be disturbed again due to project phasing: Rough grade; and Stabilize and maintain stabilization according to SECTION 902. DO NOT clear and grub areas unless work will actively be performed in the exposed area (or portions of the exposed area) within 7 calendar days on exposed steep slope areas (40% or greater) or within 14 calendar days for all other exposed areas. If areas are cleared and grubbe d and not finish graded, not part of project phasing and no meaningful work toward the completion of the bid item is performed within the exposed area (or portions of the exposed area) for 7 calendar days on exposed steep slope ar eas (40% or greater) or 14 calendar days for all other 201 – CLEARING AND GRUBBING 200-2 exposed areas, stabilize and maintain stabili zation at these exposed areas according to SECTION 902 at no cost to KDOT. Remove and dispose of the cleared vegetation and debr is. If authorized by the Engineer, dispose of the cleared vegetation and debris on the right-of-way. Backfill and compact all stump holes, except in areas of excavation. Backfill the stump holes to the level of the surrounding ground. If the backfill area is within the limits of the new construction, compact the backfill to the type of compaction and within the moisture range designated in the Contract Documents. Provide temporary erosion and pollution control according DIVISION 900.
201.4 Measurement and Payment
The Engineer will measure the clearing and grubbing as a lump sum. Stabilization of finished areas w ill be measured and paid for under DIVISION 900 bid items. Exempt areas specified in subsection 201.3 will not be measured for payment. Payment for "Clearing and Grubbing" at the contract unit price is full compensation for the specified work.
