STATEMENT OF WORK

Front End Wheel Loader and Motor Grader Rental

Part 1 – Scope, Background, and Objective

1.1 Scope of Work

The Contractor shall source and provide one (1) Front End Wheel Loader and one (1) Motor

Grader for a period of twelve (12) months. Both pieces of equipment shall be delivered to:

Joshua Tree National Park

Oasis Visitor Center

74485 National Park Drive

Twentynine Palms, CA 92277

1.2 Background

The park currently lacks sufficient in-house heavy equipment to support large-scale roadway surface treatments and grading operations. Existing equipment resources are limited and unavailable for sustained use, particularly for project-based rehabilitation efforts. As a result, the park must secure long-term rental equipment to effectively complete critical maintenance projects and address deferred maintenance.

1.3 Objective

The Contractor shall furnish:

1. One (1) mid-size articulated front-end wheel loader (Caterpillar 950 class or approved equal) for roadway rehabilitation and cold mix asphalt overlay operations at Black Rock

Campground and other park maintenance activities.

2. One (1) mid-size motor grader for cold mix asphalt overlay operations at Indian Cove

Campground.

All equipment shall be delivered in fully operational condition and shall meet or exceed the specifications outlined in this Statement of Work. Equipment must be capable of precision grading required for proper base preparation, drainage control, and surface shaping prior to placement of cold mix asphalt.
