WYDOT Section 106: Control of Material

Control of Material

106.1Quality Requirements

1 Provide and use materials that meet the specified requirements. The engineer will use procedures from the Materials Testing Manual , or products listed on the Department’s Qualified Product List (QPL) to determine whether materials meet the requirements.

2 When standard test methods or specifications are referenced in the contract, use methods and specifications in accordance with Subsection 105.3, Conformity with Contract.

3 When the contract refers to a particular product or manufacturer, followed by the phrase “or an approved equal,” the department is establishing a standard of quality, durability, and design; it is not limiting competition. The department will accept products of other manufacturers if they are equal to those specified and the engineer approves in writing.

4 Submit certifications in accordance with Subsection 800.1, Manufactured Product Certifications.

106.2Inspection and Tests at Source of Supply

1 The engineer may inspect materials at their source. Ensure the engineer’s access to relevant areas of the suppliers’ production facilities. Provide facilities to enable sampling of material at no additional cost to the department. Before their incorporation in the work, the engineer may retest materials tested at their source.

106.3Sources, Sites, and Haul Roads

106.3.1 General

1 Provide material sources, stockpile sites, plant sites, and associated haul roads if not designated in the contract as department-furnished.

106.3.2 Department-Furnished

106.3.2.1 General

1 The department may acquire and make available for the contractor’s use, material sources, stockpile sites, plant sites, and haul roads. For material sources, interpret the department’s data from the boring logs in accordance with Subsection 102.5, Examination of Documents and Work Site.

Control of Material SECTION 106

2 The contractor has the right to determine the equipment and amount of work needed to produce a material that meets the contract requirements. The engineer may specify the location of the procurement of material from any portion of a deposit.

3 Perform the following at no additional cost to the department:

1.Moving equipment within a pit;

2.Moves made for the contractor’s benefit; and

3.Moves made due to the presence of unacceptable material, except when the

original location was designated by the engineer.

106.3.2.2 Available Material Sources

1 In the contract, the department may show available sources for required materials. The engineer may approve changes from available sources by issuing a “Contract Amendment” (Form E-61). When the contract allows and the contractor elects to use a department- furnished source as a contractor-furnished source, a Contract Amendment is not required. The department will determine the quality of the material from the proposed source in accordance with Subsection 106.3.3.3, Approval of Materials.

2 When the contractor chooses to use a source other than those initially designated as available, excluding commercial sources, the department will pay for quantities up to the specified amount at the contract unit price for the affected pay item(s). The department will consider as incidental the following costs associated with the change:

1.Additional costs from increases in quantities for:

1.1Overburden storing and placing;

1.2Topsoil storing or placing;

1.3Haul length;

The engineer will not approve use of a proposed source that is not or has not been commercially active before the contractor has obtained environmental clearances in accordance with Subsection 106.3.3, Contractor- Furnished, and given copies to the engineer before starting work. The contractor is responsible for delays associated with obtaining and using such sources.

106.3.2.3 Mandatory Material Sources

1 When the department designates a source as mandatory, use it.

106.3.2.4 Stockpile Sites, Plant Sites, and Haul Roads

1 In the contract, the department may show available stockpile sites, plant sites, or haul roads. The engineer may approve, in writing, requests to change from available sites and roads to contractor-furnished sites and roads in accordance with the procedures and assessment of additional costs specified in Subsection 106.3.2.2, Available Material Sources, but may not issue a “Contract Amendment” (Form E-61).

106.3.3 Contractor-Furnished

106.3.3.1 General

1.A United States Geological Survey 7.5 minute quadrangle map showing the location

of the features and activity.

2.Necessary permits from owners, land management and regulatory agencies

(BLM, WDEQ, etc.), and approved mitigation plans, as appropriate.

Such processes include, but are not limited to, rolling, extruding, machining, bending, grinding, drilling, and coating or similar processes to manufacture or modify the physical properties or chemical composition of iron or steel. Coatings include any protective or value-enhancing process. The department will, however, accept:

1.Foreign iron or steel components whose total combined value, including the cost of

delivery to the project, does not exceed 0.1 percent of the total contract amount, or $2,500, whichever is greater.

Control of Material SECTION 106

2.The use of the following nondomestic raw materials: scrap, pig iron, and

processed, pelletized, and reduced iron ore.

3.Nondomestic items that are used temporarily then abandoned in place at the

contractor’s convenience.

2 For iron and steel components, obtain from the manufacturer and provide to the engineer a material test report or certification that states clearly the country of manufacture. Include two copies of the itemized invoices for materials used and transportation costs for shipment to the project.

3 Ensure that foreign-made bolts, fasteners, and associated hardware are tested and certified by an independent domestic testing laboratory in accordance with Division 800, Materials. Submit the test data and certifications to the engineer before use.

4 T o seek a waiver of these provisions, submit a written request to the engineer. Accompany the request with supporting information showing that the specified steel or iron products are not manufactured in the United States in sufficient, available quantities of satisfactory quality. The department will not grant time extensions or pay compensation for delays resulting from processing such a request.

106.11Stockpiling Aggregate

1 Clear and grub aggregate stockpile sites in accordance with Section 201, Clearing and Grubbing. Ensure that sites are firm, smooth, and well-drained. Do not stockpile aggregate in a manner that causes or allows contamination or excessive degradation.

2 When not included as a pay item, the stockpiling of aggregates for construction is incidental to the associated pay items.

106.12Contractor Testing

.1 General

1 When speci fied, take responsibility for development of a mix design as applicable, material sampling, quality control testing, and quality acceptance testing.

106.

12.2MEASUREMENT and PAYMENT

1 The engineer will measure Contractor Testing as a complete unit.

2 The department will pay as follows:

Pay Item Pay Unit Measure to the Nearest Pay to the Nearest Contractor Testing LS LS LS

Control of Material SECTION 106

3 The department will divide and pay out the lump sum as follows:

1.Twenty-five percent with the first monthly progress payment;

2.Twenty-five percent with the monthly progress payment that follows the engineer’s

written acceptance of the contractor mix design or the beginning of placement of tested material(s); and

3.The final 50 percent upon completion of the sampling and quality control and

quality acceptance testing.

4 The department will not pay directly for changes to an accepted contractor mix design made for the contractor’s benefit; complete it at no additional cost to the department. At a negotiated lump sum price, the department will pay for changes to an accepted contractor mix design made at the engineer’s request.
