Site work for a road / highway in Defiance, Ohio. Completed plans call for site work for a road / highway.

The award of the contract will be made to the lowest and best bidder; however, only those proposals (bids) from contractors that are determined to be qualified with experience in the construction of BAT and/or similar facilities will be considered. A. Furnish all labor, supervision, permits, materials, equipment, shop drawings, tools, services, testing and incidentals required to complete the Work required by these Bid Documents, project Technical Specifications, project Construction Drawings, and Contract Documents. After completion of the Work, and upon demobilization, the Contractor shall leave the Site free of Contractor's structures, equipment, and debris and securely enclosed. B. General Description of the Specific Work Items 1. Mobilization/Site Preparation a. Move all the equipment and supplies and obtain the various services the Contractor requires to make his offices and temporary facilities operational. Setup the Contractor's area for offices, employees, parking and other requirements of this Project's Bidding Documents. b. Provide equipment, materials, labor and other items for preparation of the Work. c. Install temporary construction access road(s), drainage ditches, and associated structures necessary to do the Work. d. Install surface water and erosion control measures to keep the Work areas, including the borrow grid areas free of ponding waters that may cause delays or problems for performance of the Work. Prevent sediments from leaving the Work Site. i Complete any necessary survey tasks required to perform the Work. ii Provide the required submittals to the Engineer and/or Owner. 2. Phases 8 and 9 BAT Cells Construction (The order of the Work listed below is not intended to be the required order the Contractor must follow.) a. Perform survey services as necessary to complete the Work as required by the Construction Plans and Technical Specifications. b. Prepare the engineered subgrade in Phases 8 and 9 so as to meet the required elevations, contours, grades, and dimensions as shown on the construction drawings in preparation of the recompacted soil liner (RSL). Areas containing vegetation shall be over excavated by 12 inches, removed and stockpiled at a location(s) designated by the Owner's representative or the Engineer. Additional soils below the vegetative layer that are necessary to be removed to meet minimum design grades are to be stockpiled separately at a location(s) designated by the Owner's representative or the Engineer. Areas within Phases 8 and 9 requiring additional soil to meet minimum design grades shall be filled with structural fill. Remove standing water and accumulated sediments from surface water pumping location at the northwest corner of Phases 8 and 9.The depths of sediment is unknown. Sediment needs to be removed until competent subgrade is exposed. If the excavation of the sediment extends below the bottom of recompacted soil liner grades, fill with structural fill to subgrade elevations. c. Obtain the Engineer and CQA Consultant approval of the engineered subgrade via acceptable proof-rolling of the subgrade. d. Construct and install the RSL in accordance with the project Construction Drawings and Technical Specifications. The construction shall be done using the specified soil from the preapproved soil borrow grids. Lifts shall be constructed in accordance with the approved test pad. The test pad includes maximum lift thicknesses, approved compaction equipment and minimum number of passes required to achieve the required specifications. The Engineer or CQA Consultant must approve each lift prior to construction of the next lift. e. Once the RSL has been completed, prepare a smooth sub-base in Phases 8 and 9 in preparation for placement of geomembrane on top of the engineered soil components. This will be inspected by both the CQA Consultant and the geosynthetics installer just prior to installation of the geomembrane. All stones that protrude 1/4 inch or more from the surface or that are greater than 2 inches in diameter, debris or surface damage must be removed and/or repaired placement of geomembrane. The prepared geomembrane subgrade surface shall be free from soft spots, voids and ruts. After CQA Consultant and Geomembrane Installer approve the surface preparation, the Engineer may grant authorization to begin installation of the HDPE Liner system. Ohio EPA is expected to visit the project area throughout the construction project. Ohio EPA typically visits cell construction projects just prior to and during geomembrane installation. Ohio EPA may also inspect geomembrane sub base. If Ohio EPA objects to an unsatisfactory sub base, the Contractor, with input from the Engineer, if necessary, will determine what must be done to achieve an acceptable sub base. If the objection is based on the appearance or CQA data for the RSL, the Contractor shall make the appropriate correction, including removing and reconstructing at no cost to the Owner. It is very important that the RSL is constructed and maintained correctly; that the moisture and compaction requirements are met; that CQA results demonstrate compliance with the applicable specifications and requirements; and the RSL surface is prepared for Ohio EPA inspection prior to Ohio EPA's arrival. After authorization to proceed is received, install geomembrane liner in accordance with the project Construction Drawings and Technical Specifications. The liner material consists of 60 mil textured HDPE liner. This material must comply with the minimum specifications in the PTI for liner. f. After liner is installed in accordance with the applicable specifications and requirements, and properly inspected, tested, and approved by the Engineer, install the geotextile cushion layer in accordance with the project Construction Drawings and Technical Specifications. Ohio EPA may want to inspect the geomembrane liner prior to installation of the geosynthetics. If this is required, the Contractor must wait for Ohio EPA to inspect and gain approval from the Engineer prior to commencing further work above the geomembrane liner. g. After the geotextile cushion layer is installed in accordance with the applicable specifications and requirements, and properly inspected, tested, and approved by the Engineer, install the leachate collection and removal system (LCRS) in accordance with the project Construction Drawings and Technical Specifications. This includes bedding, drainage material, and piping. h. After the LCRS is installed in accordance with the applicable specifications and requirements, and properly inspected, tested, and approved by the Engineer, install the geotextile filter layer in accordance with the project Construction Drawings and Technical Specifications. 3. Stormwater Management a. Construct diversion berm and/or diversion swale around Phases 8 and 9 so that storm water is directed around Phases 8 and 9 to the surface water drainage system. 4. Forcemain and Cell Access Road a. Construct dual contained forcemain pipe from the sideslope riser pipes to the meter vault and from the meter vault to the forcemain pipe constructed for Unit 2 Phase 7. b. Construct dual contained witness pipe as shown on the drawing in accordance with project specifications. c. Construct all weather access road from the all weather access road west of Phase 7 to the entrance of the new BAT Cell (Owner to designate location). 5. Meter Vault a. Supply and install meter vault as shown on the drawings in accordance with the project specification. 6. Other Work The Owner may require additional construction tasks or Projects. These have not been defined; therefore, for the purpose of cost, there are additional Unit Price items listed in the Bid Form. These Unit Prices should be provided by the Contractor. Unit Prices should be priced as "installed and operational" meaning to include cost for electrical, etc. Unit Prices will be used to reimburse the Contractor for the additional Work. Any questions regarding the BID DOCUMENTS must be submitted to the Project Engineer (Karen Dolliver, Mannik & Smith Group) by February 11, 2026 @ 5:00 PM.
