1.0 SCOPE

This Bid Specification #5430-34359 defines the requirements for custom fish hauling tanks (henceforth referred to as “tanks”) that will be mounted on flatbed trucks and used by the California Department of Fish and Wildlife to transport and plant fish in California waters.

2.0 APPLICABLE LAWS AND STANDARDS

Laws, regulations, policies, and standards listed in this section form a part of this bid specification as cited in the text.

2.1 LAWS, REGULATIONS, POLICIES

None listed.

2.2 STANDARDS

None listed.

3.0 TECHNICAL REQUIREMENTS

Tanks must be newly built, fully welded, and free from leaks. Figures found in Appendix A referenced throughout the text are for illustration purposes, the text requirements hereafter take precedence over the figures.

The minimum total tank capacity was approximated by multiplying exterior dimensions to determine volume after accounting for inner wall, outer wall, and insulation thickness (minus 3.75 inches to length and width). The change in volume from the 2-inch sloped floor was approximated by subtracting 5.75 inches from height (3.75 inches + 2 inches).

The resulting in3 is converted to gallons (231 in3 = 1 gallon).
