STATEMENT OF WORK FOR

REPLACE VISITOR PROTECTION PASTURE HORSE FENCING

I. PURPOSE

The purpose of this project is to replace the horse paddock fence enclosing three large pastures, encompassing two small paddocks and a small corral area adjoining the park’s Visitor Protection Office. The fence has passed its normal use life and poses a hazard to the horses, employees, and park visitors. The existing fencing is coated, electric wire that is tightened at the fence corners with specialized tools and equipment. Small sections from an older, three-rail oak board fence are incorporated into the existing fence in different locations and are in poor condition. The existing fence posts have started to rot and break at the base. Poor visibility of the wire has caused numerous deer to crash into it, causing it to fail in large sections.

II. PROJECT OBJECTIVES

The project calls for the removal of the old fence and replacing it with a fence constructed of larger, 7-inch diameter posts and four (4)-rail oak boards on eight (8)-foot intervals between posts. Fill and tamp holes left by fence removal.

Once the fencing is installed, the top of the fence shall be strung with coated electric wire and one (1) electric box shall be installed to power the wire. The project includes the addition of a section of new fencing to divide one of the large pastures. Twelve, 12-foot gates will be replaced, with an additional one (1) 12-foot gate will be added for a total of thirteen (13) gates.

Since the new fence posts will be set 8 feet apart; not all of the old postholes can be re-used as existing posts are on 10-foot intervals.

The work shall be completed in two phases in order to provide for containment of the horses throughout the project. See the attached map for reference and clarification.

IV. SCOPE OF WORK

A. Remove all of the old fence and replace it with a fence constructed of larger, 7-inch diameter posts and four (4)-rail oak boards on eight (8)-foot intervals between posts.

The work includes the addition of a section of new fence that does not currently exist dividing one of the large pastures. Fill and tamp holes left by fence removal.

The work will be performed in phases. Phase One will consist of the demo and removal of the old fence and installation of the new fence in sections 1A and 1B and sections 4 and 5. During Phase One the horses will be kept in sections 2 and 3. The fence line separating sections 1B and 2 will be kept in place throughout Phase One.

Once Phase One is complete the horses will be moved into the newly constructed sections and Phase Two can begin.

Phase Two will consist of the demo and removal of the old fence and the installation of the new fence in sections 2 and 3.

B. Contractor shall furnish and install approximately 4,300 feet of four (4) boards per section, 5-foot-high oak paddock fence according to map location.

Contractor shall furnish and install (13) thirteen, 12-foot-wide, metal tube, green cattle gates. Gates will be same type and style as what is currently in place on existing fence. COR shall approve the gates prior to installation.

C. Gate posts and corner posts shall be driven in (not dug and tamped) to a depth of 48” below ground level. In line posts shall be driven in (not dug and tamped) to a depth of 36”, plumb with tops of gate posts level. All line post shall be set 8 foot on center, fencing boards shall be attached with a hardened spiral shank galvanized (coated) nail (16d or 3 1/2" long) three nails per end board. The bottom fence rail shall be installed at a height of 12” above the ground (measured from the bottom edge of the board).

The subsequent rails will be spaced 8” above the lower board. A 5-foot vertical board will be nailed to every line post. The vertical board will both cover the board cuts and add another set of nails to help secure the rails.

All gate posts and corner posts shall be 8” diameter full round pine post, pressure-treated with chromated copper arsenate (CCA) to a density of 0.4 lb/ft3 or higher. In line fence posts shall be 6”-7” diameter half round pine posts (or faced posts) pressure-treated with chromated copper arsenate (CCA) to a density of 0.4 lb/ft3 or higher. The tops of all in line post shall be cut at a 45-degree angle toward the outside of the fence (NO CAPS). Fence Boards shall be 1”x6”x16 foot rough sawed

P a g e 3 | 13 oak plank. Boards will be staggered wherever possible so that board ends are not in line with the boards immediately above or below.

Corner bracing will NOT be required for the corners/gate post areas.

Gates - 12 foot 18 gauge gates with six bars, green tube gates. Tubes, 1 5/8”. The two bars at the bottom of the gate will be spaced closer together than those at the top.

Gate hinges shall be designed to permit the gate to swing a full 180 degrees and support 18 gauge gates. Direction of swing will be appropriate for the location of the gate and approved by the COR. Adjust hinges and bracing, allowing gate to hang level and swing freely.

Gate latches shall be ½ inch galvanized metal with an 8” X 3/16” chain, and heavy 4” staple.

Fence mounting hardware shall be appropriate to fence wire. Hardware shall be approved by COR.

All fence boards shall be installed on the inside of the post, keeping a smooth surface against the horse (prevents them banging/hooking a shoulder on a post). This also makes the fence stronger as the board will not pop out when a horse leans or rubs hard on it.

If rocks are encountered during the installation of the posts the rocks will need to be excavated if possible and the posts subsequently embedded in concrete to the requisite depth outlined in the previous sections for the respective post types. If the rocks are not able to be removed, they may be broken apart in situ and the post sunk/secured in concrete.

All alternative materials or methods shall be approved by the COR and submitted in writing for approval.

D. The coated electric wire may be installed as each phase is completed or it may be installed after all of the new fence is complete. Contractor shall furnish and install approximately 4,300 foot of coated electrical wire along the top rail of the board fence, one (1) power box powered with battery backup of sufficient size and capacity to power the system with proper grounding system. Install one strand of electrified

12.5 gauge galvanized high tensile steel wire designed for use with horses. Wire casing shall have a brown colored polymer coating as specified in 2.2 D.

The wire should be Kencove Hotcote Fence Wire, or similar coated electrical wire, with heavy duty tension springs, stainless steel Hayes style wire tighteners and black, nail on claw insulators.

P a g e 4 | 13

The coated electric high-tension wire will be strung along the inside, top edge of the top rail of the wooden fence so as to provide a shock deterrent to the horses around the entire fence line, including interior fence sections.

On interior sections the wire will be strung on both sides of the top rail to provide shock deterrent to horses on either side of the fence. At all gates where the electric wire crosses, the wire will be buried to allow passage through the gates.

The wire will be encased in PVC type conduit and routed down the gate post to the ground. The conduit encased wire will be buried to a depth of 12-inches and span the opening of the gate to the next gate post where it will travel up the gate post to the top of the fence. Electrical work shall meet National Electric Code.

All wire will be strung and interconnected to create a single continuous loop able to be energized by a single power unit.

There shall be break in the wire line above the two water troughs for the safety of the horses.

A single, AC powered (no battery powered back-up), electric power box will be installed along with a proper grounding system (minimum of three interconnected 8-foot ground rods).

The fence charger shall be located near the currently in place solar charger near the tack room. The distance to the fence from this location will be less than 10 ft.

Gates shall not be electrified. Circuit shall run through conduit underground beneath gates.

Install adequate grounding material for each charger. Do not use the well, water pipe, or the power system ground as a ground rod. Do not use any metal rod which has a painted surface. Rods shall be driven a minimum of 6 to 8 feet deep into permanently moist earth.

Do not install fence ground rods within 50 feet of any utility ground system. Install first ground rod within 20 feet of charger. Use clamp to attach ground wire to ground rods. Follow manufacturer instructions for grounding installation. It is critical that the fence is properly grounded.

Grounding Rods – 3/8” to 5/8’ diameter, 6 to 8 foot long corrosion resistant metal rod such as galvanized steel.

E. Double sided yellow electric fence warning signs shall be placed on the fence in accordance with current regulations and standards. Signs shall be bilingual or trilingual and NOT display manufacture advertising.

F. Test and certify fence for appropriate voltage after installation of equipment.

The park will additionally assist in their identification and provide available pertinent plans/documents. The fence line must be swept with a magnet to ensure that all nails, screws and other metal objects from the fence are removed from the area.

H. The approximate locations of new or existing gates are shown on the map with crosses. One new gate will be installed in the fence line separating sections 1A and 1B. One gate will be relocated from its current location on the fence line separating sections 1B and 5 to a new location on the fence line separating sections 1A and 5.

All other existing gates will remain in their current locations. The COR will confirm the placement of all gates. Some of the existing gates may be retained by the park for later use. The COR will identify the gates that will be retained.
