The scope of services generally consists of the following elements. Individual elements as shown below may or may not be awarded and contracted, based on available budget: A. Intake Tower Replacement Project and Geotechnical Needs The existing intake tower is original to the 1967-1968 construction of Lake Orange and has surpassed its useful design life. The Project will include but will not be limited to: a water control plan (e.g., an engineered temporary coffer dam or Owner-approved equal), demolition of the existing intake tower, construction of a new reinforced concrete intake tower – constructed in-situ – with all appurtenances, including but not limited to a tower security/intruder prevention gate, a pedestrian access walkway/bridge, site access safety measures inclusive of OSHA-compliant handrails, a primary lake drain gate/valve, a primary tower drain gate/valve, three (3) intermediate lake level control gates/valves, manual and/or automated drain gate/valve actuators, a lake level monitoring device (ultrasonic level gauge or Ownerapproved equal), a permanent rain gauge, OSHA-compliant tower access manway(s) and fixed interior access ladder(s), programming and integration of applicable appurtenances to the County’s existing Supervisory Control and Data Acquisition (SCADA) system, erosion and sedimentation control measures, and site restoration. No traffic control or site perimeter security measures will be required, as the existing intake tower is fully contained within County property. The services requested in this RFQ are specific to geotechnical exploration to better characterize the subsurface conditions (depth to rock and stiffness of overburden soils) around the existing intake tower to aid in the design of the replacement intake tower and a temporary cofferdam for the construction of the replacement intake tower. The drilling will also include a boring in the dam crest to provide soils data for the evaluation of construction loads on the dam and to install an open-standpipe piezometer with a flush-mount cover that is rated for traffic loads. NOTE: The ideal Provider should have professional experience with barge or boat based geotechnical drilling operations and experience or familiarity performing geotechnical investigations associated with Class C (High Hazard) dams. B. Detailed Scope - Geotechnical Investigation: The successful Provider, once contracted with the County, will be required to deliver the following general scope of work, on time and within available budget: 1. Location of onsite utilities in the vicinity of the intake tower via locate ticket submittal to the public utility locator (i.e., NC811), prior to drilling. 2. Drilling management and observation with soil and rock core sampling, logging, and laboratory tracking/testing. During the project, all work areas shall be kept in a neat and orderly manner. All discarded items shall be placed immediately into heavy duty trash bags and removed from the site on a daily basis. Absolutely no litter shall be discarded at the site. At the completion of drilling,
