QUESTIONS AND ANSWERS:

1.

QUESTION: In lieu of the Poligon Model REK 20x34; Will it be suitable if we have one of our subs, design & fabricate the Cabana based on the spec requirement details?

ANSWER: YES, It is acceptable to have a like structure designed and fabricated by a local engineering and fabricating facility. Please note all the structural and architectural elements must meet or exceed the criteria for the specified pre-engineered model provided as the basis of design including but not limited to, material shapes and sizes, fasteners and connections and coatings. The qualified engineer must also provide stamped and signed plans for the structure and the foundation as required in the construction specifications and drawings. Contractor must provide additional time for submittal review by the Government since it would not be a pre-engineered structure and the Government will require full submittal to verify all criteria of the structure and foundation have been met.

DESIGN AMENDMENTS

1. The cabana minimum eave height shall be changed from 13 feet to 13 feet – 6 inches minimum clearance. Please replace Sheet 2 construction drawings, construction specifications table of contents, page 010000-1 and page 130470-2 with REVISION 1 showing the change from 13 feet to 13 feet – 6 inches for minimum clearance eave height. Revision 1 pages are attached.

PART 2 - PRODUCTS

2.1 MATERIALS

A. Pre-Engineered Shelters: Prefabricated steel structure, Model REK 20x34 with 13 foot - 6 inch eave for the individual shelter as manufactured by Poligon, 4240 136th Ave Holland, MI

49424 Phone 616.888.3500, or approved equal, with the following salient features.

1. Structural framing: Structural steel tube minimum ASTM A500 grade B or cold-formed box sections minimum ASTM A570b grade 55. “I” beams, tapered columns, open channels, or wood products shall not be accepted.

2. Fasteners: ASTM A325 high strength bolts and A563 high strength nuts, ASTM A36 anchor bolts, self-drilling screws, rivets.

3. Metal roofing: 24-gauge galvalume factory finished with Kynar 500 paint system.

Standing seam panels shall be 12 to 16 inch wide. Seams shall run with the pitch of the roof for proper drainage. Color shall be selected from manufacturer’s standard color options to match existing cabana structures at the site, as approved by the

Contracting Officer.

4. Metal roofing trim shall match the color of the roof and shall be formed from 24 gauge painted galvalume steel as follows.

a. Panel end caps shall be pre-bent to a “U” shape to fit over ridge end of roof panels.

The inside of the “U” shall match the roof color.

b. Metal ridge caps shall be preformed with a single central bend to match the roof pitch. They shall be hemmed on the sides.

c. Roof peak cap shall be supplied on all structures that do not include a cupola.

d. “J” channel shall be shaped like a “J” with colored metal on the outside wrapped around 20 gauge galvanized steel core. “J” channel shall be applied all along the eave to strength and straighten the eave. Both colored metal and galvanized core shall have 7/16” weep holes 6” on center.

e. Eave splice channels shall be provided to fit behind “J” channel butt joints to create strength at the joint and maintain a straight eave line.

f. Special “J” channel corner trim shall be provided which fits over the main “J” channel to simplify final detailing of corners.
