The Contractor shall be responsible for the repairs of damage to existing utility lines that are indicated or made known to the Contractor prior to start of clearing and grubbing operations. When utility lines which
23、are to be removed are encountered within the area of operations, notify the Contracting Officer in ample time to minimize interruption of the service. Refer to Section 01 30 00, ADMINISTRATIVE REQUIREMENTS and Section 01 57 19.00 20, TEMPORARY ENVIRONMENTAL CONTROLS for additional utility protection
24、.3.2 CLEARING*NOTE: Any clearing which requires the removal and disposal of structures that obtrude, encroach upon, or otherwise obstruct the work should be indicated and specified in the Section 02 41 00 DEMOLITION AND DECONSTRUCTION.When grubbing is included as part of the contract, delete require
25、ments for herbicides.Where loose rocks, boulders, or rock piles are present on the surface of the areas designated to be cleared, appropriate provisions will be inserted to provide for the disposal of such material. Where stone occurs that can be economically used in the project, provision will be m
26、ade for the proper stockpiling of such stone in a designated area adjacent to the location of its intended use.If only minor structures will be encountered, such work may be included. Where large structures are to be demolished, the requirements of this work will be covered in Section 02 41 00 DEMOL
27、ITION AND DECONSTRUCTION.Herbicides intended for controlling vegetative growth should be specified and used with caution on hazardous waste sites to avoid contributing to site contamination.*Clearing shall consist of the felling, trimming, and cutting of trees into sections and the satisfactory disp
28、osal of the trees and other vegetation designated for removal, including downed timber, snags, brush, and rubbish occurring within the areas to be cleared. Clearing shall also include the removal and disposal of structures that obtrude, encroach upon, or otherwise obstruct the work. Trees, stumps, r
29、oots, brush, and other vegetation in areas to be cleared shall be cut off flush with or below the original ground surface, except such trees and vegetation as may be indicated or directed to be left standing. Trees designated to be left standing within the cleared areas shall be trimmed of dead bran
30、ches 40 mm 1-1/2 inches or more in diameter and shall be trimmed of all branches the heights indicated or directed. Limbs and branches to be trimmed shall be neatly cut close to the bole of the tree or main branches. Cuts more than 40 mm 1-1/2 inches in diameter shall be painted with an approved tre

Apply herbicide at the rate of _ in accordance with the manufacturers label to the top surface of stumps designated not to be removed.SECTION 31 11 00 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-3.3 TREE REMOVALWhere indicate
32、d or directed, trees and stumps that are designated as trees shall be removed from areas outside those areas designated for clearing and grubbing. This work shall include the felling of such trees and the removal of their stumps and roots as specified in paragraph GRUBBING. Trees shall be disposed o
33、f as specified in paragraph DISPOSAL OF MATERIALS.3.4 PRUNINGPrune Trim trees designated to be left standing within the cleared areas of dead branches 38 mm 1 1/2 inches or more in diameter; and trim branches to heights and in a manner as indicated. Neatly cut limbs and branches to be trimmed close
34、to the bole of the tree or main branches. Paint cuts more than 32 mm 1 1/4 inches in diameter with an approved tree wound paint.3.5 GRUBBING*NOTE: Delete the second sentence when this work is included under another section or sections of the project specification.For hazardous waste sites, the amoun
35、t of grubbing performed in contaminated areas should be minimized due to potential added costs for disposal of contaminated materials and health and safety concerns.*Grubbing shall consist of the removal and disposal of stumps, roots larger than 75 mm 3 inches in diameter, and matted roots from the
36、designated grubbing areas. Material to be grubbed, together with logs and other organic or metallic debris not suitable for foundation purposes, shall be removed to a depth of not less than 455 mm 18 inches below the original surface level of the ground in areas indicated to be grubbed and in areas
37、indicated as construction areas under this contract, such as areas for buildings, and areas to be paved. Depressions made by grubbing shall be filled with suitable material and compacted to make the surface conform with the original adjacent surface of the ground.3.6 DISPOSAL OF MATERIALS3.6.1 Salea
38、ble Timber*NOTE: Do not include this article in SOUTHNAVFACENGCOM projects. Instead, notify the Project Manager, obtain an estimated value if timber is saleable, and include the following in the BASIS OF BIDS statement: “Bidders are advised that there is marketable standing timber, having fair marke
39、t value which the Government appraises to be $_, within the limits of construction. The Contractor is required to pay the appraised amount to the Government within 30 days after notice to proceed has been given. This is to be deposited in the SECTION 31 11 00 Page 6Provided by IHSNot for ResaleNo re
40、production or networking permitted without license from IHS-,-,-Navys forestry account.“Verify with the natural resources office for the installation the most appropriate option.1. The first option should be used when the Contractor will be required to cut and stack saleable lumber for the Governmen
41、t.2. The second option should be used when the Government will harvest saleable timber prior to award of the contract.3. The third option should be used when the Contractor will be required to pay the Government an appraised amount for the saleable timber on the project site. Use of the third option
42、 must be approved by EFD/EFA legal counsel for NAVFAC projects. When the felled timber has a distinct commercial value, the disposal of such timber may be left to the Contractor provided the Contracting Officer has reasonable assurance that the bidders will consider the value of the salvageable timb
43、er in estimating their bids. An applicable length will be inserted in the blank. At hazardous waste sites, timber removed from areas of contamination is normally not salable due to liability concerns.4. The fourth option should be used when the disposition of cleared materials is left to the Contrac
44、tors discretion. When the timber that can be obtained from felled trees is not of sufficient commercial value to warrant salvaging, this paragraph may be deleted, and the Contractor permitted either to make use of or to dispose of such timber in an approved manner.When this specification is being used for the remediation of hazardous waste sites, this paragraph should define how both contaminated and non-contaminated materials will be disposed of. As an alternative, disposal requirements could
