Sulphur Banks Bridge Materials

For Delivery to Hawaii Volcanoes National Park

1 Crater Rim Drive, HNP HI 96718

OVERVIEW

Hawaii Volcanoes National Park (HAVO) intends to purchase commercially available yellow cedar lumber.

HAVO requires the yellow cedar lumber to replace the existing, deteriorated wooden footbridge along the Sulphur Banks Trail, ensuring safe and durable pedestrian access through a geothermally active and environmentally sensitive area within Hawaiʻi Volcanoes National Park. The lumber must possess exceptional natural resistance to decay, rot, and insect damage without the use of chemical treatment, and must be capable of withstanding prolonged exposure to high moisture, sulfurous gases, and acidic conditions typical of the project site. Additionally, the material must demonstrate adequate structural strength for pedestrian bridge applications, high dimensional stability to minimize warping and checking, compatibility with corrosion-resistant fasteners, and be sourced from sustainably managed forests to meet federal environmental compliance requirements.

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