SECTION A – PROJECT DETAILS

A1.0 Project Purpose and Scope:

The project calls for the construction of wood post and cable fences at various locations within the Rainbow Gardens Area of Critical Environmental Concern just east of Las Vegas, Nevada.

The purpose of these fences is to prevent unauthorized access points and illegal roads onto lands adjacent to the fence thereby allowing sensitive vegetation to recover and thrive.

All fences can be accessed using Lake Mead Boulevard. The nearest fence will be located approximately 4.2 miles east of the eastern edge of Las Vegas and the furthest approximately 7.3 miles east of Las Vegas.

From Lake Mead Boulevard, all fences are accessible via established dirt roads. Locations are shown on Exhibit 1 – Vicinity Map / Fence Locations.

A2.0 Project Descriptions:

Fence locations and descriptions are broken out as Base Option, Option 1, Option 2, and Option

3. The fence described in the Base Option is the minimum amount of fence to be constructed under this contract.

The Government may or may not exercise Options 1 thru 3 individually, collectively, or in combinations based on bid price and available Government funding. In this manner, the Government may choose to exercise one or more Options in Fiscal Year 2023 which begins on October 1, 2022 and ends on September 30, 2023.

Government and Contractor shall field confirm all fence locations prior to the start of fence construction.

A2.1 Base Option
