Contract Opportunity

Part 1 – General Information

1.1 General: This is a non-personal services contract to provide chemical and mechanical treatment of noxious and pest weeds on U.S. Army Corps of Engineers (COE) owned lands around Dworshak Dam and Reservoir (Dworshak Project). The Government will not exercise any supervision or control over Contractor employees. Contractor employees shall be accountable solely to the Contractor who, in turn, is responsible to the Government.

1.2 Introduction: The Contractor shall provide all personnel, equipment, personal protective equipment (PPE), supplies, facilities, transportation, tools, materials, supervision, and other items and non-personal services necessary to perform chemical and mechanical treatment of noxious and pest weeds as defined in this Performance Work Statement

1.3 Background

1.3.1 The COE has a mission to manage natural resources and act as steward of its lands and waters. Vegetation control is part of the COE’s natural resources management mission to “manage and conserve those natural resources, consistent with ecosystem management principles, while providing quality public outdoor recreation experiences to serve the needs of present and future generations.” The spread of noxious and pest weeds is a major threat to the management and conservation of those resources.

1.3.2 Dworshak Project staffs recognize this threat and have focused efforts on weed control through the use of chemical, mechanical, and biological control measures. The current Dworshak Weed Management Plan employs the use of chemical control in areas accessible by vehicle or deemed critical for immediate containment/eradication. Mechanical control is used in areas deemed unsuitable for the use of chemical or biological control methods.
