This amends a previously published combined synopsis/solicitation for Redwood posts to be delivered FOB to Manzanar National Historic Site. This amendment adds additional requirements to the following sections of the synopsis/solicitation: 1) SPECIFICATIONS FOR REDWOOD, 2) REQUIREMENTS FOR PACKAGING REDWOOD FOR SHIPPING, and 3) DELIVERY AND UNLOADING ON SITE. All other terms and provisions remain the same. Accordingly, the above three sections of the synopsis/solicitation are deleted in their entirety and replaced with the following: SPECIFICATIONS FOR REDWOOD: All Redwood shall be coastal redwood of the Sequoia sempervirens species. All Redwood shall be endorsed by the Forest Stewardship Council (FSC). All Redwood shall meet or exceed the grade requirements for Construction Heart grade as described in the latest edition of the Standard Specifications for Grades of California Redwood Lumber. All Redwood shall be Free of Heart Center (FOHC). All Redwood shall be rough sawn to the full dimension specified if available. If full dimension is not available, then it is to be as full sawn as available. All Redwood posts shall have both ends cut squarely. As soon as possible after cutting, ends of redwood posts shall be sealed with Anchor Seal, or approved equal, to control moisture loss and prevent warping and checking. Only the ends of posts shall be coated with sealer. The redwood posts are to be used in the rehabilitation of an historic fence and will be installed rough sawn as they arrive from the mill, without any further milling or planing. Care must be taken in applying the sealer so that no sealer is applied to the sides of the posts. After cutting, all Redwood is to be sticker stacked as noted below to prevent warping and twisting. There are no requirements for moisture content. REQUIREMENTS FOR PACKAGING REDWOOD FOR SHIPPING: Redwood posts are to be shipped in sticker stacked bundles not to exceed 1500 pounds in weight. To prevent infection of Redwood, sticker lath shall be free of stain and decay and have a moisture content of less than 20%.

Redwood posts shall be stacked in layers with 1x2 or 1x3 sticker lath of a uniform thickness separating each layer of posts. Posts on each layer shall be laid tightly against each other, and shall also be aligned vertically. Stickers shall be placed approximately 12" from the ends of posts and spaced uniformly, with a maximum of 24" between stickers. Bundles of sticker stacked posts shall be banded with flat metal straps aligned with the stickers. The metal straps shall be tight and flat against the redwood to prevent shifting during shipping and warping or twisting during seasoning. Redwood shall be protected from crushing by the metal straps, including the use of suitable protection at corners. DELIVERY AND UNLOADING ON SITE: Redwood shall be delivered to the Auditorium area of Manzanar National Historic Site (the Park) which is located on the west side of US Highway 395 approximately 5 miles south of Independence, California.

Contractor shall provide all equipment and supplies, including a forklift, to off-load and stack Redwood at the delivery site. Redwood bundles shall be shimmed to level on the site to prevent shifting or warping during seasoning. Stacked bundles shall be aligned vertically and horizontally with supporting bundles and shall have a minimum air space of 6" between the ground and stacked Redwood. Posted 08/25/99 (W-SN372531).
