Deer-Proof Fenceline Installation Natural Resources Conservation Service (NRCS)

Plant Materials Center, Hoolehua, Hawaii

Statement of Work

MAY 2018

Deer pressure at the Hoolehua Plant Materials Center (HIPMC) located at 4101 Maunaloa Highway, Hoolehua, Hawaii 96729, has increased drastically within the last couple of years due to the installation of deer-proof fencing by neighboring land managers. The HIPMC needs to ensure the integrity of ongoing plant studies and prevent property and plant damage from the increased deer pressure. These needs can be satisfied by installing a deer-proof fence. Installation costs can be reduced significantly by fencing only the portion of the HIPMC where plant studies are conducted. Costs to meet HIPMC needs can be reduce further by taking advantage of existing neighboring deer-proof fence lines that already protect a considerable amount of the HIPMC’s property. By connecting to these existing fence lines, the needs of the HIPMC can be fulfilled at a substantially lower cost. There are [2] options for this project. The HIPMC will determine which option is most suitable depending on the final cost of each option. OPTION A puts a fence through the center of the HIPMC running east-to-west. This option still has a risk for deer intrusion since there is an off-site gate that the HIPMC has no control of. OPTION B includes OPTION A in addition to a second length of fence on the south boundary of the HIPMC to mitigate this risk.

I. Project Options:

A. OPTION A (see Figure 1 and 2)

1. Removal and disposal of existing fenceline, posts, and fencing debris.

2. Fence line ground prep

3. Installation of 8 foot deer-proof fence.

a. Total length approximately 2,300 linear feet

b. [3] Gates.

4. Connect 8ft fence line to existing 4ft fence lines.

B. OPTION B (see Figure 3 and 4)

1. Removal and disposal of existing fenceline, posts, and fencing debris.

2. Fence line ground prep

3. Installation of 8ft deer-proof fence.

a. The total length is approximately 3,400 linear feet

b. [4] Gates.

4. Connect 8ft fence line to existing 4ft fence lines.

A pre-construction meeting is required on-site to review specifications, fence layout, and to answer any questions. Project must be approved as satisfactorily completed within 120 calendar days of bid award date. Access to work area will be during regular business hours, 7am to 3:30pm, Monday through Friday.

No work on Saturdays or Sundays nor on fedewral holidays. Upon completion of the fence installation, a site inspection will be made to determine if the materials and design and installation adhere to the specifications documented in this Statement of Work.
