This work shall also include the protection of all vegetation and objects designated to remain.
Construction Requirements
General
The Engineer will establish the limits of work and designate all trees, shrubs, plants and other things to remain. The Contractor shall protect and preserve all items designated to remain.
Clearing and Grubbing and Tree Removal
All surface objects and all trees, down timber, rotten wood, stumps, roots, snags, brush, other vegetation, rubbish, and other protruding obstructions, not designated to remain, shall be cleared and/or grubbed, including disposal as required.
In areas under roadway embankments, from which top soil or unsuitable materials are to be removed or which are designated to be compacted, all stumps and roots shall be removed to a depth at least 50 cm below the original ground surface and at least 50 cm below the bottom of the lowest pavement layer.
In roadway cut areas, all stumps and roots shall be removed to a depth of not less than 50 cm below the finished subgrade level.
Clearing and grubbing of pits, channel changes and ditches will be required only to the depth necessitated by the excavation within those areas.
Voids left after removal of roots shall be filled with suitable compacted material.
Topsoil Stripping
In areas under roadway embankments or where designated by the Engineer, the Contractor shall remove the topsoil and dispose of it as directed by the Engineer.
In general the removal of topsoil shall include only the removal of soil which is sufficiently fertile to encourage or sustain a growth of vegetation.
Removal of topsoil over any designated area shall be executed to the depth as directed by the Engineer, and the topsoil shall be kept separate from other excavated material.
Protection of Areas Designated to Remain
In areas designated by the Engineer, the Contractor will be responsible for the protection and routine maintenance of existing shrubs, trees and grassed areas. On completion of the Works these areas will be returned to the Employer in the same condition as before and any damage due directly or indirectly to the Contractor's operations shall be made good at his own expense.
Disposal of Cleared Material
The Contractor shall have the right to use un-saleable timber (or saleable timber when permission is granted in writing by the appropriate Government agency or authority) for his own purposes in connection with the Contract; always provided that he has ascertained and complied with the requirements of the appropriate Government agency or authority.
Saleable timber shall be neatly stored in an approved accessible place within or near the right-of-way as directed and shall be trimmed and stacked in accordance with the requirements of the appropriate Government agency.
All other timber, except timber to be used, and all brush, stumps, roots, logs, and other refuse from the clearing and grubbing operation shall be disposed of at locations provided by the Contractor.
The roadway and adjacent areas shall be left with a neat and finished appearance. No accumulation of debris shall remain on or adjacent to the right-of-way.
