Drilling Monitoring Government Bids & RFPs

Lot 1: *** ONLY ONLINE BIDS WILL BE ACCEPTED FOR THIS RFB. *** Emailed and hard copies delivered by any method WILL NOT BE ACCEPTED. On this line, Bidders must enter $ 0. 00 for Contract Amount in the e- procurement system. Actual Contract Amount must be entered on " Official Bid Document" and submitted as an attachment in the e- procurement system. Vendors should review and update, if necessary, all addresses and contact persons for their account prior to bid submission. This information will carry forward to a contract if awarded, therefore please ensure all information is correct. ** Entire Official Bid Document and Bid Bond ( if required) should be combined as one PDF and uploaded** The project will begin as an exploratory geotechnical investigation and dig two exploratory pits and drill 4 exploratory borings. The pits will be dug at the two surface expressions of subsidence to gather additional information necessary to determine if the subsidence is related to historic mining in the Hawesville Coal Seam. Historical documents suggest this coal seam was mined for steam coal for river boats on the adjacent Ohio River. Four exploratory borings will also be advanced in the general area to determine if mine voids exist and if there has been any collapse in the mine voids if they do exist. Percussion drilling and air- hammer drills are not allowed on this project. Methane monitoring is the responsibility of the contractor, and if methane is encountered, the contractor must immediately implement a plan to secure the area. After the initial exploratory work, AML staff will determine if the subsidence is mine related or if it could be related to collapsing buried domestic tanks or related to karst geologic conditions that may exist at the site. If it is determined that AML eligible mining is associated with the subsidence events, then soil and rock drilling will be required as generally shown in the plans with location adjustments made as necessary by AML staff. AML employees will utilize a downhole camera to verify current c
