Specifications for:

Lumber Materials for Pu’uloa Petroglyph Boardwalk

For Delivery to Hawaii Volcanoes National Park

1 Crater Rim Drive, HNP HI 96718 Revision 1 – 9.10.26

OVERVIEW

Hawaii Volcanoes National Park (HAVO) intends to purchase commercially available boardwalk materials including decking lumber, structural lumber, fasteners, and hardware. HAVO requires the boardwalk materials to support the repair, rehabilitation, and long-term maintenance of the elevated pedestrian boardwalk system at the Puʻuloa Petroglyph site. The boardwalk protects significant cultural and archaeological resources by directing visitor traffic over fragile lava fields and petroglyph features while providing safe and public access.

The materials must therefore ensure structural integrity, durability, and minimal environmental impact within a federally protected cultural landscape exposed to high ultraviolet radiation, volcanic gases, wind, heavy rainfall, and corrosive coastal air.

The required items must meet the following salient characteristics, which represent the Government’s minimum needs:

• Materials shall be durable in volcanic and marine environments and resistant to corrosion, UV degradation, moisture intrusion, fungal decay, and volcanic ash or gas exposure.

• Products shall be non-toxic and environmentally compatible; treatments and coatings must not leach harmful chemicals and must comply with National Park Service environmental standards.

• Fasteners and hardware shall be 316 stainless steel or equivalent corrosion-resistant material suitable for high-humidity and salt-air conditions.

• Materials must maintain dimensional stability and resist warping, splitting, shrinkage, or deformation under prolonged sun and moisture exposure.

• CAC is a wood preservative used in pressure-treated lumber to protect against rot, fungal decay, and termite damage. It is intended for outdoor structural applications, including above-ground and ground-contact use, where protection against moisture, decay, and insects is required.

These characteristics are essential to protecting significant cultural resources while ensuring visitor safety and long-term performance.

A. MINIMUM SALIENT CHARACTERISTICS or GENERALLY ACCEPTABLE SPECIFICATIONS Note: All products must meet the requirements set forth by the BUY AMERICAN ACT.
