Reservoir Lining in Waianae Valley Ranch

This contract involves the procurement and installation of a reservoir lining for a small, circular earthen reservoir located in Waianae Valley Ranch, Hawaii. The reservoir measures approximately 60 feet in diameter with a height ranging from 4 to 6 feet, and features an embankment on the upslope side about 10 feet high. The foundation consists of soil and large boulders. The lining material must be at least 40 mil thick, capable of preventing water seepage and vegetation growth, and must accommodate an inlet pipe and discharge pipe. The site is remote, accessible only via a ranch road suitable for 4WD vehicles, with strict adherence to environmental protection rules due to sensitive surrounding areas. The project requires compliance with Hawaii's HCE standards at the time of award, and vendors must be prepared for logistical challenges such as no onsite water, electricity, or restroom facilities, and the need for safety measures including a 20-pound fire extinguisher on site. The solicitation, posted by the Hawaii Department of Land & Natural Resources, is open for responses until May 6, 2025, with a contract value estimated between $50,000 and $150,000. The project emphasizes environmental sensitivity, safety, and adherence to specific site access protocols, with additional documentation available including site photos, maps, and directions to a pre-conference meeting. The primary point of contact for inquiries is Jeff Tanaka, reachable via email or phone.
