Overview: The Iowa Department of Transportation (Iowa DOT) is requesting bids for Shoulder Aggregate, 3/4" Class "A" Stone (Rock) both delivered and stockpiled at DOT garages, and rock to the road.
The Iowa Department of Transportation (Iowa DOT) is requesting bids for Class “A” crushed stone Article 4120.04 or Class “C” gravels Article 4120.03 for which 75% or more of the particles retained on the 3/8 inch (9.5 mm) sieve have at least one fractured face as defined in Materials I.M. 305. Crushed gravel must meet the gradation below. The testing shall be done prior to delivery.

Lines 1-104: Delivered & Stockpiled at Shops

Material shall be delivered to the site and dumped where directed by the District Maintenance Manager or designee. DOT Maintenance forces will construct stockpile. This is the reference to the term “Delivered” under the "Line Items" Tab. No elevators will be required.

Option 1 – Roadside delivery with chain spread or dumps

The contracted supplier will be responsible for dumping material in temporary piles near the specified roadway for the Iowa DOT to pick up and place on the roadway shoulder for r outes desig nated in the solicitation document. The rate of delivery should not exceed the amount the Iowa DOT expects to place on the shoulder within 1 day after delivery to the temporary day pile.

If Iowa DOT requests chain (rough) spread of product the supplier will furnish and apply granular material directly to road shoulders as specified to address edge rut needs.

Lines 105-179: Rock to Road

Option 2 – Roadside delivery and placed by supplier

Bids for each garage location listed on line items 105-179 are to be inclusive of delivery to any section of road within their specific areas of responsibilities. Routes will be from mile posts to mile posts. All road weight limits shall be followed.

Placement needs will vary by location; requirements may be as low as 1 or exceed 8 tons per 100 feet. The Iowa DOT frequently uses a spread pattern of 3 feet wide and 2 inches thick. The pattern requested of the bidder may vary but will be determined and provided to the supplier at the time of order.

Iowa DOT personnel will prioritize road repairs not to exceed their allotted budget. Once determined, suppliers will be asked to deliver class “A” crushed stone or class “C” gravel to specific roadside locations. Suppliers will be given specific delivery instructions including but not limited to desired tonnage, date, location and dumping instructions.

Throughout the contract period DOT personnel will contact successful bidders to place material orders and provide locations within their areas of responsibilities for delivery. The supplier will have 10 working days after notification to make deliveries.

Iowa DOT will provide all necessary traffic control except where indicated on the lines for Manchester, Dyersville and Anamosa lines 177-179 garages in district 6.

Suppliers will be required to deliver product to the designated location as specified by Iowa DOT personnel. Acceptable types of trucks will be determined between DOT and supplier. This material will not be stockpiled but will be spread or dumped according to DOT’s instructions at each location as needed.

At routes designated in the contract documents the supplier will be responsible for placing the material on the shoulder by use of a shouldering machine furnished and operated by the supplier without dumping on the pavement. Supplier’s equipment must be capable of spreading the granular shoulder materials in a uniform layer of the desired thickness and width in an evenly loose condition. Locate the wheels of the spreader so they do not operate on the 1 foot (0.3 m) width of pavement adjacent to the edge of the shoulder. Once spread, compact the aggregate using a pneumatic tired roller or a steel vibratory roller with a minimum of four complete coverages of the entire surface, then followed with a minimum of one complete finish coverage using a steel tired roller.
