Statement of Work Purpose

The purpose of this Statement of Work is to solicit a qualified contractor to furnish all materials, components, labor, fabrication, and installation services necessary to supply and install a complete and fully operational scarifier system on an existing motor grader.

2. Background

The motor grader (figures 2 &3) is not currently equipped with a scarifier attachment or supporting hydraulic components. In order to improve surface preparation, grading efficiency, and roadway rehabilitation operations, a fully functional scarifier system must be installed.

The scarifier itself will be provided by the government, however, no hydraulic cylinders, hoses, pump, control lever, or mounting assemblies are currently available. The awarded contractor shall provide all required components and complete installation. The government furnished equipment was removed from another motor grader and is on site and in operational parts. Please reference figure 1.
