Statement of Work

Project Title La Grande Forestry Sciences Lab Security Fencing

General Information

1.0 Background and Purpose

The USDA Forest Service, Pacific Northwest Research Station has the need for Security Fencing at the La Grande Forestry Sciences Laboratory (LFSL) site. The LFSL is located at 1401 Gekeler Lane in La Grande, Oregon 97850. The LFSL facility is approximately 13,693 square feet and located on 5.5 acres of land.

The construction of the fence is paramount in keeping employees, property, and research safe.

The facility has had multiple vehicle break-ins and several agency items stolen over the past few years. Also had an individual living on grounds for several days. There has been evidence of people walking through compound at all hours. The resulting contract will improve the site security and will protect the property and research.

2.0 Definitions

Contracting Officer (CO) means a person with the authority to enter into, administer, and/or terminate contracts and make related determinations and findings within the limits of their warrant.

Contracting Officer’s Representative (COR) means an individual, designated and authorized in writing by the contracting officer to perform specific technical or administrative functions.

Contractor Requirements

3.0 Technical Requirements / Tasks

Tasks:

Provide and install a six-foot-tall chain link security fence around to enclose the remaining unfenced areas of the LFSL facility. The footings should be a minimum of 36 inches deep due to the 24-inch frost line in La Grande. Install eight inches of drain rock at the bottom of each pole footing. One gate will be installed that will consist of one 6 foot high and 10-foot-wide man gate (non-motorized).

The work will be performed outside, the immediate area (grounds) parking lots are fairly level. There are exterior water bibs and power outlets on site. Bathroom facilities are available within close proximity of the administrative lobby.

The concrete mix will be 4000 psi. Keep the air temperature surrounding the fresh concrete above 40 degrees F for a period of five days after the concrete is placed. Mix dry concrete and water thoroughly according to the manufacturer. Concrete footings will be two inches above the finished ground with a slight sloping away from the posts.
