Specifications include, but are not limited to: The State of Nevada Purchasing Division is seeking proposals from qualified vendors to provide bat gate construction and installation services statewide on an as needed basis. 1.1.1 Historical hard rock mines have, over time, become significant roosting habitat for dozens of wildlife species. In some cases, these artificial roosts serve as surrogate habitats where natural cave roosts are no longer available. Adits and shafts have expanded the range of some wildlife species. Hundreds of these underground habitats provide year-round shelter for congregations of birds and bats that sometimes number in the thousands of individuals per roost. 1.1.2 Anticipated end products include stable cave/mine roosting bat and bird habitats as well as the security of the traveling public when in close proximity to these abandoned mines. 1.1.3 The purpose of this RFP is to ensure the availability of qualified construction professionals on an “as needed” basis for the entire geographical area of the State. Therefore, this contract may be awarded to multiple vendors to meet the geographical coverage within the State of Nevada. Steel gates or grates will be constructed in adits, shafts, stopes or any other AML feature as agreed to by the awarded vendor(s) and the State’s designee. The purpose of these gates or grates is to maintain airflow and wildlife access while preventing unauthorized human access into the mine.
