Joint Base Pearl Harbor-Hickam Wave Attenuator Install

This project includes all investigation, surveying, and construction necessary to design and install a wave attenuator as described herein. The project includes all demolition, relocation, temporary construction and restoration necessary to produce a complete and useable facility. The project includes installing a new floating wave attenuator system that is approximately 300 feet long and securing it to the ocean floor in the configuration noted herein. The work includes, but is not limited to the following:

1. Design of Wave Attenuator Site Development: There is not landside site development work required. The project has received approval from all authorities as referenced in Section J of the attached solicitation.

The work includes developing the detailed engineering, shop drawings and specifications for the floating wave attenuation systems, auger piles, mooring systems (chains, cables, etc) signage, and all related appurtenances and elements as well as specifying construction techniques in accordance with all requirements governing Rainbow Bay Marina JBPHH, Hawaii for certain components of the construction work such as anchoring operations for a complete and usable floating wave attenuation system.

2. Purchase and Installation of Wave Attenuator The new wave attenuator shall be a “whisper wave” product (or equal) and secured to the ocean bottom as required. Reference Attachment Section, Wave Attenuator Layout. The attenuation system shall be able to withstand the greater of; waves at least 4’ high or as called for in the wind wave analysis.

Anchorage to the sea bottom (encl 3c) shall be provided and installed in sufficient size, quantity and spacing to resist the environmental loads listed in the wind wave analysis. The connective ties that connect the floating wave attenuator to the anchors shall be as recommended by the manufacturer and able to withstand the forces listed in the wind wave analysis (encl 3d). They shall be of an appropriate material, that is elastic in nature (i.e. Sea Flex or equal) or rigid (i.e. chains or cables).

No utilities are to be installed in or extended to the wave attenuator system. Solar-powered LED lights to mark the location of the floating wave attenuator shall be installed as required by applicable law. Four mooring balls shall be installed an accordance with Marine spacing standards to allow mooring of vessels up to 50’ in length.
