6、L WORKS08/08*NOTE: This guide specification covers the requirements for furnishing all labor and equipment and performing all work required for clearing and disposal of trees, stumps, clearing fences, buildings, and other structures and disposal of debris, trash, and materials resulting from clearin
7、g operations.Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable items(s) or insert appropriate information.Remove information and requirements not required in respective project, whether or not brackets are pr
8、esent.Comments and suggestions on this guide specification are welcome and should be directed to the technical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the Internet.Recommended changes to a UFGS should be
9、submitted as a Criteria Change Request (CCR).This guide specification has been prepared for use in reservoir clearing operations. It has two alternates, one which is concerned with the clearing of timber lands and the other one deals with the removal of man-made structures, debris, etc.*PART 1 GENER
10、AL1.1 UNIT PRICES*NOTE: If Section 01 22 00.00 10 MEASUREMENT AND PAYMENT is included in the project specifications, SECTION 31 10 00 Page 3Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-this paragraph title (UNIT PRICES) should be deleted from this
11、 section and the remaining appropriately edited subparagraphs below should be inserted into Section 01 22 00.00 10.No paragraph covering partial payment has been included in this guide specification. If partial payment is to be made, it should be addressed in the contract at the appropriate place (e
12、.g., Section 01 22 00.00 10 MEASUREMENT AND PAYMENT. One method, which has been used, is described here in general terms and may be incorporated when necessary. To estimate the value of work completed during each period, the zones are divided into the class of clearing involved. Class A clearing inc
13、ludes, as nearly as can be determined from aerial photographs or other means, all the wooded area with the exception of scattered trees, fringe growth along roads and fences, etc. Class B clearing contains all of the open, cultivated or pasture lands and those relatively open areas containing scatte
14、red trees, fringe growth along roads and fences, etc. The numbers of hectares (acreages) in each class should be estimated in advance and tabulated under the partial payment clause of the specification and thenceforth not be subject to change even if it is discovered that the original classification
15、 may have been in error. The most difficult class is arbitrarily assigned ninety work units for clearing, disposal, and clean-up. The number of work units in the other classes are estimated by comparison with the base class. The final estimate might be as follows:Class A, Zone 1 _ hectares (acres) x
16、 60 = _ work unitsClass B, Zone 1 _ hectares (acres) x 15 = _ work unitsClass A, Zone 2 _ hectares (acres) x 90 = _ work unitsClass B, Zone 2 _ hectares (acres) x 25 = _ work unitsTotal work units = _The value of a work unit is determined by dividing the contract price by the above total. The value
17、of the work completed during any period will be determined by multiplying the number of hectares (acres) of the various classes completed in each zone, as estimated by the Contracting Officer by planimetering areas from Government progress maps, by the work units in that class, totaling these figure
18、s and multiplying this total by the value of an individual unit as determined above. The estimate of the Contracting Officer will be final. For the purpose of apportioning the classes of work completed during any period, the felling and decking ready for burning or removal is considered as 50 percen
19、t of the work required and the removal and/or burning and clean-up will be considered as the remaining 50 percent.SECTION 31 10 00 Page 4Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-*1.1.1 Clearing (Timber and Structure)1.1.1.1 PaymentPayment will

21、en brush and trees, for the purpose of distinguishing clearing requirements, is that trees, as used, will be considered as that woody growth not falling within the limits of brush as defined below.1.2.2 Brush*NOTE: Alternate 1.*Brush is that growth which is less than 50 mm 2 inches in diameter measu
22、red 150 mm6 inches from the ground on the uphill side and is less than 2 m 6 feet in height measured from the ground on the uphill side.1.2.3 Structures*NOTE: Alternate 2.*The term “structures“ includes buildings or portions thereof, walls, silos, storm or root cellars, cisterns, wells, windmills, p
23、it silos, water towers, etc. Structures shall be removed or filled to the ground surface.1.3 PROJECT/SITE CONDITIONS1.3.1 Aesthetics and Pollution Control*NOTE: Alternate 1.*1.3.1.1 Ground AreasAll ground areas in the zone of normal pool level fluctuations which are disturbed by clearing operations
24、and which would become subject to erosion SECTION 31 10 00 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-will be protected or restored.1.3.1.2 Construction Roads*NOTE: Insert type of cover crop and seeding rate, if applicable.*All constructio
25、n roads proposed for use by the Contractor for removing salvaged timber or for access to the work area shall be approved, as to location and alignment, prior to construction. Where such roads are determined to be of no value to project operation or will not serve recreational access needs after proj
26、ect construction, the areas occupied by these roads will be restored as nearly as possible to pre-construction conditions by reasonable grading and seeding _ of a native cover crop along with the planting of seedling trees if in a tree cover area.1.3.2 Existing Conditions*NOTE: Paragraphs of Alterna
27、te 1 and 2 should be deleted if not applicable.*1.3.2.1 Boundaries*NOTE: Alternate 1.When land lines or identifiable topographic features, such as roads, railroads, streams, etc., are used in place of or in addition to contours to designate zone boundaries, the descriptions indicated below should be
28、 so modified.*The area to be cleared under this section contract is divided into two (2) zones having the general limits as defined below and as indicated on the drawings and maps and aerial photographs, which form a part of this contract.a. Zone 1 - Included in this zone is that portion of the rese
29、rvoir area bounded byat a lower elevation than the _ meter foot msl contour line.b. Zone 2 - Included in this zone is that portion of the reservoir area above the _ meter foot msl contour line and below the _meter foot msl contour line.*NOTE: For b. above, use the contour elevation of Zone 1.*1.3.2.

Graves and headstones or markers will be relocated by others.1.3.2.3 Markings of Zones*NOTE: Alternate 1.*The _ and _ contour lines have been establishe
32、d in the field by the Government. The contour lines are identified by stakes on the lines or by painted bands on trees near the lines. The _ contour is marked with _ paint and the _ contour is marked with _ paint. Other boundaries are marked by identifiable topographical features or by section or fr
33、actional section lines.1.3.2.4 Zones*NOTE: Alternate 2.When Alternate 2 is used independently of Alternate 1, the boundaries should be completely described. Similarly, this section should be further modified to include all other applicable portions of Alternate 1.*The boundaries of the zones are as
34、described in paragraph BOUNDARIES, subparagraphs ZONE 1 and ZONE 2.1.3.2.5 Fencesa. Zone 1 - No clearing of fences is required in Zone 1; however, the Contractor may, as an option, remove any or all fence materials from the area and dispose of such materials off the reservoir area.b. Zone 2 - All fe
35、nces in Zone 2, except in those areas where no timber clearing is required, shall be cleared.1.3.2.6 StructuresBurn combustible materials obtained from removal of structures in accordance with paragraph DISPOSAL OF MATERIAL or dispose of them off the reservoir area. Where filling of structures is re
36、quired, fill to within 450 mm 18 inches of the ground surface and made with noncombustible materials such as masonry rubble, and other debris. When all available debris has been used in filling, all remaining unfilled portions, together with the above 450 mm 18 inches shall be completely filled to t
37、he ground surface with earth, borrowed as directed by the Contracting Officer. The top surfaces of fills shall be neat in appearance and smooth enough not to constitute a hazard to persons or livestock.SECTION 31 10 00 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted withou
