TECHNICAL SPECIFICATIONS FOR 3 STRAND LAY-DOWN WIRE FENCE

CONSTRUCTION

CLEARING

The fence shall be located in the center of cleared right-of-way. A six foot right-of-way on each side of the fence is to be cleared of logs and trees. Limbs on trees shall be removed to a height of 8 feet on trees used as posts in the fence. Limbs and brush removed from the right-of-way shall be scattered off the right-of-way. All slash must be kept at least 20’ from any game or livestock trails. All stumps on the right-of-way shall be flush cut and be higher than 3 inches from the ground.

HAZARD TREES

Any dead trees less than 16” in diameter within 25 feet of the fence line will be felled prior to construction of the fence. The felled hazard trees will be bucked up to a distance of 6 ft. on either side of the fence and the material removed from the 6 ft. right-of-way on each side of the fence. The remainder of the felled hazard trees need not be limbed or bucked. If there is a question as to the necessity of felling a specific tree, the contractor shall consult the ODFW or FS Contracting Officer (CO).

FENCE LINE LOCATION

All fence line locations are flagged with ribbon identified by the CO. Gate locations are flagged with ribbon identified by the CO. Deviations from the flagged line of more than 20 feet will need approval from the Forest Service. No fence will be constructed within the floodplain of Sheep Creek except for crossings.

CONSTRUCTION

All fence construction shall follow specifications outlined below and in Attachment C and

Attachment D.

4.1 LINE WIRES

Three Wire Fence: wires shall be spaced as follows: The bottom wire (barbless 12.5 GA) will be a minimum of 16 inches from ground level and a maximum of 18 inches, the next two (barbed

12.5 GA) shall be spaced at eight inch intervals for a total height not to exceed 40 inches unless the fence is located across a steep slope. In this situation the top wire will not exceed 38 inches.

The wire will be hung on the uphill side of the fence if the flagged line is located on a steep slope or as directed by the Forest Service. Wire will not be “woven” between tree ties or t-posts. Keep wire on the side away from the stream for all T-posts. It is preferred to attach the fence to other anchors and trees on the same side if possible.

Wire will be double wrapped on all constructed pull points and single wrapped on live tree pull points. Leave adequate space for tree growth on tree tie stretch points (12” minimum space)

4.2 POSTS

Construction shall be with 5 1/2 foot 1.33 steel T-type posts set approximately 16-18 feet apart.

The spacing may be slightly closer to keep the bottom wire at an acceptable height above the ground line. Live trees or line jacks may be used in lieu of steel posts. If live trees are used, they must be located within two feet of the established line (an off-set must be used to maintain the stretch line, be a minimum of 8" dbh and must have a nailer ( "scab" ) attached as shown in.

Only Western larch, Ponderosa pine, or Douglas (Red) fir may be used as tree ties, unless otherwise approved by the Forest Service. Line jacks will be constructed as shown in. Steel posts shall be driven into the ground, past the top of the flange plate. It is acceptable to pre-drill post holes in rocky ground to permit the use of posts in these conditions. If this method is used, the flange may be knocked off prior to steel driving; however, the post must be secure in the hole with no wobbling. Steel posts shall be relieved of upward pull of wires by use of dead-man rock anchors and tie-downs as shown in. Tie-downs can be secured using a large rock or a T-post, driven at a 45-degree angle parallel to the fence (no more than 18 inches of post can remain out of the ground.) There can be no more than ten steel posts in a line (max 200 feet) without having a scabbed live tree ( 8" dbh or larger ) or a line jack to support the fence line.

4.3 STAYS

48”Split or rough sawn larch stays shall be used. Unless, otherwise stated approved by CO, TWO stays will be evenly spaced between each steel post or figure four. Stays will be attached to the fence using 1 ¾ inch galvanized staples.

4.4 GATES

The locations of the gates will be flagged by the Forest Service. Gates shall be 12-14 feet wide.

Each end of the gate shall be attached to either: trees, rock jacks, rock cribs, or H-braces. Rock cribs will be constructed as shown in. If H-braces are used, double H-Braces will be required.

Gates shall be constructed with five barbed wires spaced in accordance with specifications shown

in. Gate tightener’s will be installed on all gates.

4.5 WATER GAPS

Water gaps will be constructed to allow water passage during spring runoff using the specifications in the technical drawings.

4.6 WIRE STRETCHING

Wire will be tightened adequately to set the wire twists and remove factory kinks. It is, however, important to refrain from stretching the wire excessively. Excessive tension will weaken the barbed wire by removing the capacity for it to stretch. Location of stretch points will be determined by topography and the availability of tie-trees.

4.7 SPLICING

Splices in the wire shall be Western Union or pigtail eye splice, with no less than six wraps. All wraps shall lie directly adjacent to each other, thus forming neat, tight wraps.

4.8 STRETCH JACKS/LINEJACKS/ROCK CRIBS

Rock Jacks/Line Jacks should not be spaced farther than 200 feet apart unless there is a tree-tie, rock crib, or H-brace within this interval. Tree-ties or H-braces may be substituted for rock jacks.

Rock jacks or line jacks will be placed at the top and bottom of all abrupt breaks in the slope.

A shallow hole (12 inches deep) shall be dug to keep the jack/crib from sliding if the jack is used as an end or in a pivot point in the fence.

Use two nails placed at a binding angle at each nailed junction in all jacks. One-half the length of each nail should be in the piece being nailed to. Notching of the outside piece may be necessary to allow full contact of each face. Nails will be driven at right angles to the annual ring. Nails should not be closer than 6 inches to the end of any piece to minimize splitting. Nailed junctions should have sound wood against sound wood, no bark between.

Each of the bottom corners shall have a rock set under the corner to allow settling of the jack, but to keep the jack floor from settling to the ground. DO NOT perch the jack on rocks. All wood will rest on the ground.

All jack corners will be wrapped twice with 12.5 GA smooth wire to prevent future separation.

Rock cribs or double jack/stretch jacks will be used for corners, stretch points, and deep draw crossings. The rock load for these structures shall be 500 pounds or more of rock. Line jacks used every 200 feet or at the breaks of hills or swales shall be 200 pounds of rock. No log chunks or other weight will be acceptable.

4.9 FIGURE-FOURS

Figure-fours will be required in locations where steel posts cannot be driven into the soil to specifications. Figure-fours shall be constructed using 48” split/sawn larch pieces for the stay portion of the figure four. 48” heavy stays can be used for the vertical nailers. 5’6” pieces will be used for the legs of the figure four as indicated in the exhibits. 6” helix nails shall be used for securing the figure four.

4.10 TREES

Solid live trees over 8 inches dbh may be used in place of posts, provided they are located not over 2 feet out of fence line. Off-sets can be used to keep the wire inline. Only Western larch, Ponderosa pine or Douglas (Red) fir may be used, unless otherwise approved by the COR. Tree branches shall be removed completely around the fence, to a height of 8 feet. Do not cut into the cambium, this often causes tree mortality. A scab shall be securely nailed, with 6" helix nails to the tree at three points: top, center, and bottom.

4.11 H-BRACES

Double H-Braces may be used as stretch points if no tree-ties or rock is available for rock cribs.

If used in other locations in lieu of line jacks, the type of H-Brace used is dependent upon terrain, see. Posts must measure no less than 5-7 inches at the small end. Posts will be buried a minimum of 3 feet and spaced 8 feet apart. A pressure treated 4"x6" or 6” DIA treated round post will be used as the cross-piece brace between the posts. These braces will be placed approximately 40" from the ground. Two diagonally placed tension wires of double wrapped

12.5 gage smooth, double strand wire will be secured at ground level and 48" with pig-tailed ends. This is then tightened with a twitch stick made from a stay until the wire is very tight. The loose end of the twitch stick can be rested against the cross-piece.

4.12 STAPLING

Staples shall be driven at a slant to the grain of the wood to prevent the wood from splitting and will not be driven so deep as to nick the galvanized wire. Staples should be driven to allow movement of the wire between the wire and post/tree scab to prevent the wire from pulling into the scab

SECTION E--INSPECTION AND ACCEPTANCE

Inspection

Inspection for acceptance of work will be accomplished by a 100 percent visual inspection and will be based on adherence to the specifications. In the event visual inspection finds less than satisfactory work is being performed, re-work will be required at no additional cost to the government. Areas not adhering to specifications will be flagged, identified to the contractor and documented in the daily diary. In the event damage to previously inspected portions of the fence is found, whether from natural events or manmade, the contractor will be responsible for re-work to repair the damage before final payment is made.

1.2 Compliance Inspection

The Contracting Officer or Inspector will, by formal inspection, determine if the specified progress or methods of work are being carried out. Failure to comply with specified work standards may be cause for termination of the Contractors right to proceed, in accordance with Clause 52.249-08.

1.3 Contract Personnel

If the Contractor is absent from the project area, a Contractor’s representative (designated in writing) shall be available for communication on a daily basis while work is in progress.

1.4 Inspection of Work

Periodic inspection of work shall be made by ODFW and the Forest Service to ensure compliance with contract specifications. Periodic field inspections will be made by Contracting Officer's

Representative (COR) or the COR's designated inspector. Work not completed to contract specifications shall be reworked without additional compensation to the Contractor.

1.5 Determination of Acceptable Work

Inspection as stated above shall be performed by the Forest Service for evaluation of contract specification compliance. The Contractor will be notified in writing the fence items not meeting contract specifications. Portions of fence which do not meet contract specification will be reconstructed by the Contractor and the identified items will be brought up to the required standard before the fence will be considered acceptable.

The Contractor shall deliver all unused project materials and tools to the locations specified for each administrative unit (or other location agreed upon) at the end of the contract or any subsequent task order. If the materials and tools are not signed for upon finishing the contract, the Contractor will be charged for them as lost.

1.6 Unacceptable Work

If any portion of the project that is found to be unacceptable, the Contractor shall reconstruct the unacceptable portion to comply with the specifications. Upon completion of the reconstructed portion of the project, the Forest Service will re-inspect to determine compliance. If more than two inspections are needed for repeated deficiencies, the Contractor may be charged inspector’s time and vehicle use.

1.7 Re-inspection Upon Contractor Request

If the original inspection results are not acceptable to the Contractor, a re-inspection may be requested in writing up to 7 days after being notified of the unacceptable work. The original inspection will be re-examined by a different inspector accompanied by the Contractor. If the re-inspection confirms the original inspection as not meeting standards, the Contractor shall reimburse the Government the actual costs incurred in making the re-inspection. If the inspection indicates that work meets acceptable standards, the Government assumes the cost of re-inspection and payment will be made for the fence.

1.8 Final Cleanup

Before final acceptance, all areas occupied by the Contractor in connection with the work shall be cleaned of all Contractor's rubbish, excess materials, temporary structures, and equipment, and all parts of the work area shall be left in a neat and presentable condition
