WEATHER ENCLOSURE

Statement of work

(1) Supply a metal enclosure that will provide temporary weather protection for a piping connection on the lower side of a 199” radius horizontal tank.

The enclosure must be sufficiently ridged to withstand jacking forces applied against the base of the structure to compress the enclosure gasket against the tank.

(2) The attached sketches describe the enclosure currently in use. The new enclosures must be functionally equivalent to the existing design. Aside from the radius of the sealing frame wall construction and specific dimension are not critical but must feature all metal construction.

(3) The non metallic items in Figure 12 and Figure 14 will be provided by others.

(4) Prior to any fabrication the contractor must submit a package containing:

a. A complete set of fabrication drawings.

b. Objective Quality Evidence that shows 3 examples of similar projects completed by the contractor.

(5) No fabrication may commence until written authorization from Code

2380.2 is provided signifying technical acceptability of the design.

(6) The enclosure may be delivered fully assembled or in kit form provided assembly can be accomplished with a warehouse forklift and standard hand tools.

(7) A minimum of 3 enclosures are required.
