7. Delivery

a. Daily rate of delivery – 1,500 tons per 10-hour workday (7:00 a.m. to 5:30 p.m.);

working a 10-4 work schedule (10 days on – 4 days off, Tuesday through following Thursday).

b. Transportation: Contractors must coordinate all required approvals and/or costs associated with necessary agreements, permits etc. required for transportation of rip rap from the quarry to the load sites, whether required by local city municipalities and/or privately owned businesses prior to submission of offer to USACE Rock Island District Contracting Office.

c. Contractors must be acquainted with proposed route from quarry to load site to include road conditions, hazards, and state and federal laws and permits regarding transportation of riprap to the load site.

d. Loading Locations: The loading of riprap will take place between River Miles 606 - 609 of the Upper Mississippi River. Contractors must provide the USACE Contracting Officer with the proposed loading site and method of loading of barges as a part of bid submission, which will be reviewed prior to contract award. Proposed load site may be in Wisconsin or Iowa. Site must have adequate river depths which will allow access for USACE fleet and allow for safe mooring of government barges. At no time may the load site selected by the contractor impede or otherwise interfere with the normal navigation of commercial barge traffic.

e. All costs incurred with the deliveries are at the contractor’s expense.

f. Barge Loading: Rock fill will be required to be placed on Government barges by a method that does not allow rock fill to fall greater than four feet onto the barge deck surface. This will minimize damage to Government barges due to rock fill impact.

Regardless of the delivery method, rock fill must be uniformly distributed on Government barges to load at approximately 400-700 tons per barge load. Loaded barges must maintain a 2’ minimum walkway around the perimeter to allow deckhands to safely tie off lines on the deck. It will not be acceptable to simply dump rock fill directly on the barge surface without a method of full and even distribution. It is recommended that the Contractor utilize a long reach excavator or material handler to safely load and arrange rock onto barges.

Contractor will provide at least two (2) pieces of heavy equipment (i.e. Bulldozers, wheel loaders, etc.) to serve as anchoring points for (1) USACE barge to be loaded at a time if mooring cells or davits are not available at load site. USACE towing vessels will bring and retrieve (1) barge at a time to/from loading site. Equipment should be fully operational and capable of adjusting the position of barges, as needed. Contractor must provide the bank wires or lines to secure barges.

Specifications of the Government barges are 35 feet wide by 150 feet long. Average draft empty: 2 feet & average draft full: 6 to 7 feet. Load amounts of rock fill per barge may vary between 400 – 700 tons depending on the loading arrangement, placement site water depth, and/or ramp configuration.

Contractors must provide the USACE Contracting Officer with the method of securing and loading of barges as a part of bid submission which will be reviewed prior to contract award.

g. Delays: Delays by the Government to ensure a safe work environment may occur due to equipment maintenance, breakdowns, water levels, or any number of river or weather conditions that may arise during deliveries. Additionally, the government may need to temporarily halt the receiving of rock to conduct channel maintenance. If a delay occurs, the Government Point of Contact (POC) will immediately notify the Contractor and the Contracting Officer (KO) of the cause and the anticipated duration of the delay. The KO will then negotiate an extension to the contract completion date once the delay has been resolved. The POC will notify the Contractor (within 24 hours) when deliveries can resume. Depending on the length of the delay, additional time (days) may be added to the duration of the contract.

h. Delivery start date: Contractor must be available between the dates of August 01, 2025 –

November 30, 2025. Project start/stop dates may vary due to current workload of the Project Maintenance Fleet or unforeseen delays mentioned above.

i. Delivery completion date: Based on contract award/start date and minimum Rate of Delivery = 1,500 tons/day, the entire Base quantity must be delivered no later than three

(3) weeks after first delivery.

j. Work Schedule: The Contractor will be required to deliver rock following a 10-4 work schedule. The contractor’s 10-day work week will begin on Tuesday where the contractor will begin placing rock onto USACE secured barges at the load site; Monday is treated as a travel/staging day for USACE employees. USACE will begin cycling loaded/unloaded barges that same Tuesday and through the remainder of the 10 working days. The Second Thursday of the work week USACE personnel will shut down operations at 12:00 PM and prepare to travel home for the weekend. One empty barge will be left at the load site for the contractor to load on the Thursday of shutdown. The contractor will not load rock after 12:00 PM on the Thursday of shutdown to allow ample time for USACE personnel to secure barges for the following days off and then travel home. The schedule will vary slightly depending on where federal holidays fall within the work week.

k. Quality Control: The Contractor and the Government POC will verify rock receipts and running totals daily. A once per week update of totals must be provided by the Contractor to the Contracting Officer and POC, by close of business Thursday of each week that deliveries are in progress.

l. Riprap Specifications:

i. These specifications cover the furnishing of all material, labor, equipment, and all appurtenant facilities required to furnish, deliver and unload stone materials in conformity with these specifications. The stone must be furnished “freight on board” (f.o.b.) Government barges.

ii. Riprap stone must be of a suitable quality to ensure permanence in the structure and in the climate in which it is to be used. It must be free from cracks, seams, and other defects that would tend to increase unduly its deterioration from natural causes. The inclusion of objectionable quantities of dirt, sand, clay, and rock fines, as determined by the Government POC, will not be permitted. Stone must be reasonably well graded over the entire range of sizes conforming to the limitations specified to follow and further delineated on the chart included as Attachment A titled (ILDOT RR-5 Coarse Alternative Riprap Gradation Curve & Tally Chart).

Riprap Percent Finer Limits of Stone By Weight (SSD) Weight in Pounds 100 400-250 50 175-90 15 50-15

iii. Neither the breadth nor the thickness of any piece may be less than one-third of its length. All stone must be processed to remove fine particles by loading over a vibrating screen with not less than 6-inch bar spacing or by other approved methods and equipment that will result in satisfactory removal of fine particles. No individual piece may exceed the maximum gradation size by more than ten percent, i.e. 440 pounds, and the total combined weight of all over-sized pieces for each gradation must not exceed ten percent of the total sample size.

iv. Measurement: All stone for riprap will be measured for payment by weighing on state certified scales. Scales must have been certified by the state or calibrated by a company licensed by the state using certified weights, within 30 days prior to start of delivery of riprap. Scale certification documents must be presented to the POC during the first riprap gradation, prior to first riprap delivery.

v. Riprap Sources:

http://www.mvr.usace.army.mil/About/Offices/Engineering-and- Construction/Geotechnical-Branch/

Riprap meeting the requirements of these specifications can be produced from the USACE approved sources listed in the LINK above.

Riprap for stone protection must be furnished from the above listed sources.

http://www.mvr.usace.army.mil/About/Offices/Engineering-and-Construction/Geotechnical-Branch/ http://www.mvr.usace.army.mil/About/Offices/Engineering-and-Construction/Geotechnical-Branch/

After the award of the contract, the Contractor must designate in writing only one listed source or combination of listed sources from which it proposes to furnish riprap.

Listing of a source of stone is not to be construed as approval of all material from that source. The right is reserved to reject materials from certain localized areas, zones, strata, or channels, when such materials are unsuitable for riprap as determined by the Contracting Officer or COR. Materials produced from a listed source must meet all requirements of these specifications.

vi. Quality Control: The Contractor must establish and maintain quality control for the stone protection material and its operations to assure compliance with contract requirements and maintain records of its quality control for all operations including but not limited to the following:

Gradation of riprap - To assure compliance with the requirements of paragraph 7.l, the Contractor must determine the weight of pieces of each gradation of riprap as an approximate percent of the total weight before commencing placement of the riprap.

The government reserves the right to direct the location and select the material for samples to be tested.

A sample ILDOT RR-5 Coarse Alternative Riprap Gradation Curve & Tally Chart is included as Attachment A.

vii. Rock gradation (sample testing) may be conducted by the contractor in coordination with a USACE geologist and POC prior to the first rock delivery. The Contractor will make as many additional tests under the Contractor's quality control program as are needed to ensure gradation requirements are met or by the request of the POC if it suspects that the rock is not meeting the proper gradation. If materials fail to meet requirements, the Contractor must adjust its operation and verify with tests that acceptable materials are being produced. Failure to meet requirements will result in removal of materials already in place which the failed test represents. A copy of these records and tests, as well as the records of corrective action taken, must be provided to the Government.
