DNR is seeking a Vendor to replace 2 Vault Toilets as well as some bank stabilization at Rend Lake SFWA. Please refer to the IFB and attachments for more details. The Illinois Department of Natural Resources ("Agency" or "State") requests Bids from responsible vendors to meet its needs. A brief description is set forth below for Bidder's convenience, with detailed requirements in subsequent sections of this solicitation. If interested and able to meet these requirements, the State appreciates and welcomes a Bid. Brief Description: The Illinois Department of Natural Resources (IDNR) is seeking a Vendor to provide all labor, equipment and materials required to construct two (2) precast concrete single-user vault toilets, also including demolition of existing vault toilets, sidewalk construction, pavement marking, shoreline bank stabilization, and ancillary sitework at Rend Lake State Fish and Wildlife Area located in Bonnie, Illinois. The resulting contract with the awarded Bidder shall have an initial term of upon last signature to June 30, 2024. In no event will the total term of the contract, including the initial term, any renewal terms, and any extensions exceed ten (10) years. 30 ILCS 500/20-60. 1.2. SCOPE OF WORK: 1.2.1. Bluegill Hole Boat Ramp: 1.2.1.1 Demolition: 1.1. Vendor shall be required to demolish the existing CMU dual-user vault toilet and associated pre-cast holding tanks, the existing concrete toe wall pad adjacent to the vault toilet, and a section of concrete sidewalk that has been displaced due to bank erosion. The demolition includes off-site disposal of all concrete and vault toilet components per applicable disposal regulations. Per Illinois Department of Public Health (IDPH) requirements, the holding tanks shall be pumped empty prior to demolition and disposal. The estimated quantity of concrete demolition associated with sidewalk removal is approximately 294 square feet (s.f.). The dimensions of the existing CMU vault toilet are 12' x 8'-8" x 8' and the dimensions of the pre-cast holding tanks is 12' x 12' x 6'. Refer to the plan sheets in Attachment 1 for the locations at Bluegill Hole required for demolition and the approximate quantities. 1.2.1.2 Bank Stabilization: 1.1. Bluegill Hole boat ramp is situated on the southwest corner of a peninsula on the northern side of Rend Lake. Given southwest winds are the predominant wind direction for Southern Illinois, years of continual wave action has resulted in significant bank erosion. This erosion has caused steep vertical cuts, loss of significant earthen material, and has destroyed a section of sidewalk providing an ADA accessible route between the boat ramp and the existing restroom facility.In order to stabilize the bank to prevent further erosive action, approximately 280 feet (Sta. 0+00 to Sta. 2+80) of bank along the southern shoreline shall be graded and armored with riprap. The grading work will include excavating approximately 197 cubic yards of material to establish a 1.5:1 slope from Sta. 0+00 to Sta. 2+80, filling approximately 35 cubic yards of material from Sta. 2+28 to Sta. 2+80 to re-establish base elevation for the sidewalk replacement to meet the lines and grades necessary to be in compliance with ADA specifications. Once the excavation work is complete, the slope shall be covered with approximately 455 square yards of filter fabric, 8" thickness of bedding material, and then armored with approximately 455 square yards of RR5 riprap to a minimum depth of 22". Refer to Attachment 1 for plans and cross-sections of the bank stabilization area. Refer to the Illinois Department of Transportation Standard Specifications for Road and Bridge Construction (IDOT Standards) as referenced in the Project Specifications section for specifications associated with the bank stabilization activities. 1.2.1.3 Precast Concrete Single-User Vault Toilet: 1.1. Once the existing CMU dual-user vault toilet has been demolished and disposed, Vendor shall furnish and install a pre-assembled precast concrete vault toilet in accordance with manufacturer specifications. This single-user precast structure shall be in compliance with ADA guidelines. Prior to the installation of the precast vault, approximately 1'-8" of aggregate bedding shall be placed and compacted in the 6'-6" x 12' footprint of the new vault. Once the new vault has been set, the Contractor shall fill the remaining void of the excavation with the earthen material from the bank stabilization cut. This fill material and aggregate bedding shall be placed and compacted in accordance with IDOT standards. 1.2. Once the precast vault is in place, Vendor shall set the precast restroom facility. The connection between the vault and the precast structure shall be sealed in accordance with the manufacturer's specifications. Refer to Sheets D-1 through D-3 in Attachment 1 for details associated with all components associated with the precast structure. Refer to the Precast Vault Toilet Specifications provided in Attachment 2 for all design criteria, structural components, and finish details associated with the precast concrete single-user vault toilet. 1.1. Once the precast concrete vault toilet has been installed, Vendor shall prepare and form a 4" concrete sidewalk surrounding the entire bathroom facility and replace the section of sidewalk displaced by the bank erosion. The elevation of the replacement sidewalk shall be such to re-establish a maximum slope of 1:20 and a maximum cross-slope of 1:50, to meet ADA accessibility guidelines. The details and dimensions of the sidewalks are depicted on the drawings provided in Attachment 1. Refer to the IDOT Standards for specifications associated with the sidewalk installation. 1.2.1.5 Install Flowable Fill Beneath Existing Concrete Boat Ramp: 1.1. Wave action has caused significant bank erosion along the southern bank of Bluegill Hole boat ramp. In addition to the bank erosion, severe undercutting has occurred beneath the existing concrete boat ramp. This undercutting has left a void of approximately 15' in length by 4' in width by 1.5' in depth under a section of the boat ramp. To address this void, Vendor shall furnish and place approximately 3.4 cubic yards of a controlled low-strength material (CLSM) as backfill. The Contractor will construct a form along the south edge of the boat ramp utilizing plywood and staking to secure the form in place. In order to access the void space beneath the boat ramp, the Contractor shall drill holes of sufficient size, dependent on the size of piping used to place the CLSM, into the top of the concrete ramp. These holes shall be strategically located in order to ensure complete coverage of the void space. Once the CLSM has been placed, the holes shall be filled in with concrete to an elevation flush with the concrete surface of the ramp. Refer to the IDOT Standards for specifications associated with the CLSM. The CLSM fill shall conform to Section 1019.05 of the IDOT Standards utilizing Mix 1 requirements. 1.2.1.6 Miscellaneous: 1.1. Following completion of the main work tasks, Vendor shall backfill the areas adjacent to the active construction and grade to allow for positive drainage. Once backfilling/grading are complete, Vendor shall seed/straw these areas along with any areas disturbed by equipment during the construction activities.
