(DLNR) The intent of this project was to mitigate the rockfall hazard created by a previous landslide and thus increase public safety for river goers in the Wailua River State Park. Scope of work includes rock scaling, boulder demolition, anchor drilling, ring net system application, and landscaping. Prometheus worked closely with the parks department to safely control river traffic numbering in the hundreds of visitors daily via kayaks and tour boats. The Prometheus team also worked closely with full time archeological monitors as the job was in close proximity to the Hikinaakala Heiau and other historical and culturally significant Hawaiian sites. Prometheus utilized a boat in the river, a large crane, hanging bencher drills, and team of expert climbers to setup and complete work on the 300′ near vertical face. The job consisted of the installation of approximately 55 drilled and grouted rope anchors and nearly 20,000SF of ring nets and double twist mesh. The job was completed 30 days before deadline.
