1-06.1 Approval of Materials Prior to Use

Prior to use, the Contractor shall notify the Engineer of all proposed materials. The Contractor shall use the Qualified Product List (QPL), the Aggregate Source Approval (ASA) Database, or the Request for Approval of Material (RAM) form. All equipment, materials, and articles incorporated into the permanent Work:

1-06.1(1) Qualified Products List (QPL)

The QPL is a listing of manufactured products that have been evaluated and determined suitable for use in Highway construction. If the Contractor elects to use the QPL, the most current list available at the time the product is proposed for use, shall be used. The QPL submittal shall be prepared by the Contractor in accordance with the instructions in the QPL and submitted to the Engineer prior to use. The QPL identifies the approved products, the applicable Specification Section, and the basis for acceptance at the project level. The listing is divided into two categories, “Approved” and “Conditionally Approved”. “Approved” products are denoted with an “A”. Those products may be accepted without additional sampling. “Conditionally Approved” products are denoted with a “CA”. The acceptance and use of these products is based upon additional job sampling and/or documentation. All additional acceptance actions need to be completed prior to the material being incorporated into the Work. The Contractor shall advise the Engineer of the intended items for use from the QPL by reference to the Contract Bid item. The use of listed products shall be restricted to the Standard Specification for which they are listed and fulfillment of the acceptance requirement defined in the QPL. Qualified products not conforming to the Specifications, not fulfilling the acceptance requirements, or improperly handled or installed, shall be replaced at the Contractor’s expense. To qualify for continued listing on the QPL, products may be sampled and tested for conformance to the Standard Specifications . The Contracting Agency reserves the right to make revisions to the QPL at any time. If there is a conflict between the QPL and the Contract, the provisions of the Contract shall take precedence over the QPL. The current QPL can be accessed online at www.wsdot.wa.gov/business/materialslab/QPL.htm .

1-06.1(2) Request for Approval of Material (RAM)

The RAM shall be used when the Contractor elects not to use the QPL or the material is not listed in the QPL. The RAM shall be prepared by the Contractor in accordance with the instructions on Form 350-071 and submitted to the Engineer for approval before the material is incorporated into the Work. Approval of the material does not constitute acceptance of the material for incorporation into the Work. Additional acceptance actions as noted on the RAM need to be completed prior to the materials being incorporated into the Work. Page 1-50 M 41-10

1-06 Control of MaterialWhen requesting approval of an item that requires fabrication, both the fabricator and the

manufacturer of the base material shall be identified on the RAM.

1-06.1(3) Aggregate Source Approval (ASA) Database

The ASA database contains the results of WSDOT preliminary testing of aggregate sources as well as the results pertaining to the review of the aggregate source Quality Control Programs. Aggregate sources evaluated after January 1, 2021 shall have Quality Control Program compliant with QC 11 and QC 12. This database is used by the Contracting Agency to indicate the approval status of these aggregate sources for applications that require preliminary testing as defined in the Contract. The ASA ‘ Aggregate Source Approval Report’ identifies the currently approved applications for each aggregate source listed. The acceptance and use of these aggregates is contingent upon additional job sampling and/or documentation. The ASA database can be accessed online at the agency website. Aggregates approved for applications on the ASA ‘ Aggregate Source Approval Report’ not conforming to the Specifications, not fulfilling the acceptance requirements, or improperly handled or installed, shall be replaced at the Contractor’s expense. Aggregate materials that are not approved for use in the ASA data base may be sampled and tested by the Agency, for a specified use on a project, from the source or from a processed stockpile of the material and all cost for the sampling and testing will be deducted from the Contract. The Contractor agrees to authorize the Engineer to deduct the sampling and testing costs from money due or coming due to the Contractor. Regardless of the status of the aggregate source, whether listed or not listed in the ASA database the Contractor shall provide toxicity test results on the aggregate source in accordance with Section 9-03.21(1) upon request from the Engineer.

1-06.1(4) Fabrication Inspection Expense

In the event the Contractor elects to have items fabricated beyond 300 miles from Seattle, Washington, the Contracting Agency will deduct from monies due or that may become due to the Contractor all costs to perform plant approval and fabrication acceptance inspection for the items listed in Table 1 and costs for initial plant approval for items listed in Table 2 . Plants currently listed on the QPL for the items shown in Table 1 and Table 2 in this section do not require plant approval.

1-06 Control of MaterialThe deductions for fabrication inspection costs will be as shown in the Payment Table

below. Zone Place of Fabrication or Inspection Site Reduction in Payment 1 Within 300 airline miles from Seattle None* 2 Between 300 and 3,000 airline miles from Seattle$900.00 per inspection day** but not less than $2,500 per trip 3 Over 3,000 airline miles from Seattle $1,200 per inspection day,** but not less than $3,000 per trip *Fabrication inspection expense does not apply for initial acceptance inspection in Zone 1. Re- inspection of items due to unacceptable workmanship or scheduling errors made by the Contractor, fabricator, or facility applying protective coatings will be assessed at $70.00 per hour but not less than $140.00 per inspection. **An inspection day includes a calendar day or portion of a calendar day spent by one inspector inspecting, on standby, or traveling to and from, a place of fabrication. An additional cost per inspection day will be assessed for each additional inspector. Reimbursement will be assessed at 50% of the daily rate per Zone, per day for weekends and holidays for each on site inspector in travel status, but not engaged in inspection or travel activities when fabrication activities are not taking place. Where fabrication of an item takes place in more than one zone, the reduction in payment will be computed on the basis of the entire item being fabricated in the farthest of zones where fabrication takes place on that item. The rates for Zones 2 and 3 shall be applied for the full duration of time for all fabrication inspection activities, to include, but not be limited to: plant approvals, prefabrication meetings, fabrication, coatings, and final inspection. When an inspection is for more than one Contract the fabrication inspection costs shall be prorated as determined by the Engineer.

1-06.2 Acceptance of Materials

1-06.2(1) Samples and Tests for Acceptance

The Contractor shall deliver representative samples (from the Contractor, Producer, or Fabricator) to the Engineer without charge before incorporating material into the Work. In providing samples, the Contractor shall provide the Engineer with sufficient time and quantities for testing before use. The Engineer may require samples at any time. Samples not taken by or in the presence of the Engineer will not be accepted for test, unless the Engineer permits otherwise. The Contractor shall designate specific Contractor employees as points of contact for concrete testing and acceptance. Alternates shall be designated to ensure that direct contact is maintained during concrete placement. If designated by the Contractor to the Engineer, the concrete supplier will receive all 28-day concrete strength test results. The Engineer will designate specific Contracting Agency employees as points of contact for concrete testing and acceptance. The Contractor may observe any of the sampling and testing performed by the Engineer. If the Contractor observes a deviation from the specified sampling and testing procedures, the Contractor shall verbally describe the deviations observed to the Engineer or designated representative immediately, and shall confirm these observed deviations in writing to the Engineer within 24 hours, referencing the specific procedures and steps. The Engineer will respond in writing within 3 working days of the receipt of the Contractor’s written communications. M 41-10 Page 1-53 Control of Material 1-06All field and Laboratory materials testing by the Engineer will follow methods described in Contract documents, or in the WSDOT Materials Manual M 46-01, using qualified testing personnel and calibrated or verified equipment. The standard or tentative standard in effect on the Bid advertising date will apply in each case. Revisions to the WSDOT Materials Manual M 46-01 or revisions to other Specifications or test methods such as AASHTO, ASTM, or Federal Specifications will be considered as in effect 60 calendar days after publication.

1-06.2(2) Statistical Evaluation of Materials for Acceptance

1-06.2(2)A General

Where specified, acceptance sampling and testing will be performed by the Contracting Agency and statistically evaluated for acceptance by the provisions of this Subsection. All test results for a lot will be analyzed collectively and statistically by the quality level analysis procedures shown at the end of this Subsection to determine the total percent of the lot that is within Specification limits and to determine an appropriate pay factor. Lots and sublots are defined in the appropriate Subsection of these Specifications for the material being statistically evaluated. Quality level analysis is a statistical procedure for determining the percent compliance of the material with these Specifications. Quality level is the computed percent of material meeting these Specifications and is determined from the arithmetic mean, (Xm), and the sample standard deviation (S), for each constituent of the lot. Rounding of test results or calculations will be accomplished according to the individual testing procedure, or, if not defined in the procedure, then accomplished according to the following rule:

As an incentive to produce superior quality material, a pay factor greater than 1.00 may be obtained with the maximum pay factor being 1.05. A lot containing non-Specification material will be accepted provided the Composite Pay Factor reaches the minimum value specified elsewhere. A lot containing non-Specification material that fails to obtain at least the specified minimum Composite Pay Factor will be rejected by the Engineer. The Engineer will take one or more of the following actions when rejected material has been incorporated into the Work:

1-06.2(2)C Removed and Rejected Materials

The Contractor may, prior to sampling, elect to remove defective materials and replace them with new material at no expense to the Contracting Agency. Any such new material will be sampled, tested, and evaluated for acceptance as a part of the sublot in accordance with this statistical sampling and testing procedure. The Engineer may reject a sublot that tests show to be defective. Such rejected material shall not be used in the Work, and the results of tests run on the rejected material will not be included in the original lot acceptance tests.

F or each constituent determine PU (the percent within the upper Specification limit which corresponds to a given QU) from Table 1 . If USL is 100.00 percent or is not specified, PU will be 100. For negative values of QU, PU (e.g., N = 15 and QU = -0.5 will result in PU = 30) is equal to 100 minus the table PU. If the value of QU does not correspond exactly to a figure in the table, use the next higher value.

1-06.3 Manufacturer’s Certificate of Compliance

When authorized by these Specifications or the Special Provisions and prior to use, the Engineer may accept certain materials on the basis of a Manufacturer’s Certificate of Compliance as an alternative to material inspection and testing. The Contractor may request, in writing, authority from the Engineer to install such materials prior to submitting the required certification; however, no payment will be made for the Work in the absence of an acceptable Manufacturer’s Certificate of Compliance. The Contracting Agency reserves the right to deny the request for good cause. If for any reason the Contractor has not provided an acceptable Manufacturer’s Certificate of Compliance by the Physical Completion Date established by Section 1-08.5 , the Contracting Agency will assess the usefulness of the installed material. At the Engineer’s discretion, the Contracting Agency will either require replacement of the material by the Contractor at no expense to the Contracting Agency or process the final payment as provided by Section 1-09.9 without paying for the materials or any portion of the Work performed to install the materials provided on such a basis. The unit Contract prices for the Work shall be used to determine the amount to be withheld. Where unit Contract prices do not exist, as in a lump sum item, the amount to be withheld shall be an equitable adjustment, covering labor, equipment and materials, determined in accordance with Section 1-09.4 . The Manufacturer’s Certificate of Compliance must identify the manufacturer, the type and quantity of material being certified, the applicable Specifications being affirmed, and the signature of a responsible corporate official of the manufacturer and include supporting mill tests or documents. A Manufacturer’s Certificate of Compliance shall be furnished with each lot of material delivered to the Work and the lot so certified shall be clearly identified in the certificate. All materials used on the basis of a Manufacturer’s Certificate of Compliance may be sampled and tested at any time. Materials not conforming to the requirements will be subject to rejection whether in place or not. The Contracting Agency reserves the right to refuse to accept materials on the basis of a Manufacturer’s Certificate of Compliance.

1-06.4 Handling and Storing Materials

In storage and handling, the Contractor shall protect materials against damage from careless handling, from exposure to weather, from mixture with foreign matter, and from all other causes. The Engineer will reject and refuse to test materials improperly handled or stored. M 41-10 Page 1-61 Control of Material 1-06The Contractor shall repair, replace, or make good all Contracting Agency-provided materials that are damaged or lost due to the Contractor’s operation or while in the Contractor’s possession, at no expense to the Contracting Agency.

1-06.5 Owners Manuals and Operating Instructions

For equipment and materials that are permanently incorporated in the Work, the Contractor shall provide to the Engineer all owners manuals and operating instructions furnished by the equipment or material manufacturer.

1-06.6 Recycled Materials

The Contractor shall make their best effort to utilize recycled materials in the construction of the project; the use of recycled concrete aggregate as specified in Section 1-06.6(1)A is a requirement of the Contract. The Contractor shall submit a Recycled Material Utilization Plan on WSDOT Form 350-075A within 30 calendar days after the Contract is executed. The plan shall provide the Contractor’s anticipated usage of recycled concrete aggregates for meeting the requirements of these Specifications. The quantity of recycled concrete aggregate will be provided in tons and as a percentage of the Plan quantity for eligible material listed in Section 9-03.21(1)F Table on Maximum Allowable percent (By Weight) of Recycled Material. When a Contract does not include Work that requires the use of a material that is included in the requirements for using materials the Contractor may state in their plan that no recycled materials are proposed for use. Within 30 calendar days after Physical Completion the Contractor shall report the quantity of recycled concrete aggregates that were utilized in the construction of the project for each eligible item listed in Section 9-03.21(1)F . The Contractor’s report shall be provided on WSDOT Form 350-075A, Recycled Concrete Aggregate Reporting.

1-06.6(1) Recycling of Aggregate and Concrete Materials

1-06.6(1)A General

The minimum quantity of recycled concrete aggregate shall be 25 percent of the total quantity of aggregate that is incorporated into the Contract for those items listed in Section 9-03.21(1)E Table on Maximum Allowable percent (By Weight) of Recycled Material that allow the use of recycled concrete aggregate. The percentage of recycled material incorporated into the project for meeting the required percentage will be calculated in tons based on the quantity of recycled concrete used on the entire Contract and not as individual items. If the Contractor’s total cost for Work with recycled concrete aggregate is greater than without the Contractor may choose to not use recycled concrete aggregate. If the Recycled Material Utilization Plan does not indicate the minimum usage of recycled concrete aggregate required above, or if completed project quantities do not meet the minimum usage required, the Contractor shall develop the following:
