Appendix 6 is a detailed example project document for the Federal Open Channel Drainage Repair Work Order Contract - Package 1, prepared by Pinellas County, Florida. The document outlines five specific project sites along St. Joe's Creek, including Reach D, Reach G, and Reach H, with focus areas spanning from 37th St N to 55th St N and various avenue locations. The projects involve channel berm washout repairs, gravity support structure repairs, and restoration of damaged channel berms. Each project location is mapped with precise geographical boundaries and includes photographic documentation of existing damage conditions.

The work order contract provides technical specifications for surface preparation, concrete repair, and structural reinforcement. Key repair techniques include water blasting equipment (16,000 to 20,000 psi), epoxy crack injection, concrete surface preparation, and reinforcement installation using #4 longitudinal reinforcement bars. The document specifies detailed repair methodologies such as removing unsound concrete, preparing surfaces to a minimum amplitude roughness, and applying new concrete with specific aggregate specifications conforming to ASTM standards. A notable detail is that project names, locations, and project limits may change at the time of work order issuance, indicating flexibility in the contract's implementation.
