DIVISION S

S-1 RESPONSIBLE CONTRACTOR SP2018-6 - MODIFIED The Department cannot award a construction contract in excess of $50,000 unless the bidder is a “responsible contractor” as defined in Minnesota Statutes §16C.285, subdivision 3.

A bidder must verify it meets the minimum criteria detailed in the law. A bidder must submit its verification electronically by completing the “Responsible Contractor Verification and Certification of Compliance”. A company officer must certify statements in that section. Bidders only need to complete the electronic verification; DO NOT email, fax, or send paper forms to the Department. The Department will not accept emailed, faxed or other paper submissions and will only accept electronic verifications.

A bidder must obtain a verification from each subcontractor it will have a direct contractual relationship with. A bidder must submit signed subcontractor verifications. A contractor or subcontractor must obtain an annual verification from each motor carrier it has a direct contractual relationship with. A motor carrier must give immediate written notice if it no longer meets the minimum responsible contractor criteria. The requirement for subcontractor verifications does not apply to:

• Design professionals licensed under Minnesota Statutes §326.06; and • A business or person that supplies materials, equipment, or supplies to a subcontractor on the Project, including performing delivering and unloading services in connection with the supply of materials, equipment, and supplies. But, a business or person must submit a verification if it delivers mineral aggregate such as sand, gravel, or stone that will be incorporated into the Work by depositing the material substantially in place, directly or through spreaders, from the transporting vehicle.

A bidder or subcontractor who does not meet the minimum criteria specified in the statute, or who fails to verify compliance with the criteria, is not a “responsible contractor” and is ineligible to be awarded the Contract for this Project or to work on this Project. Submitting a false verification makes the bidder or subcontractor ineligible to be awarded a construction contract for this Project. Additionally, submitting a false statement may lead to contract termination. If only one bidder submits a bid, the Department may, but is not required to, award a contract even if that bidder does not meet the minimum criteria.

S-2 COMPLIANCE WITH TAX LAW REQUIREMENTS REVISED 08/09/19 SP2018-7 The Department cannot make final payment to the Contractor until the Contractor demonstrates that it and all its subcontractors have complied with the Income Tax withholding requirements of Minnesota Statutes, section 290.92 for wages paid for work performed under the contract. To establish compliance, the Contractor must submit a “Contractor Affidavit” either online or in paper form (IC134) to the Minnesota Department of Revenue. The contractor will receive written certification of compliance when the Department of Revenue determines that all withholding tax returns have been filed and all withholding taxes attributable to the work performed on the contract have been paid. The Contractor must then provide this written certification to the Department to receive final payment.

Every subcontractor working on the Project must submit an approved “Contractor Affidavit” from the Minnesota Department of Revenue to the Contractor before the Contractor can file its own Contractor Affidavit. The Contractor is advised to obtain the certification from each subcontractor as soon as the subcontractor completes work on the Project. Experience has shown that waiting until the project is complete to obtain the forms from all subcontractors is likely to result in significant additional work for the Contractor as it will be difficult or impossible to collect all forms.

The scope of the arbitration proceeding shall be limited to the claim(s) that the Contractor previously presented to the Engineer for decision.

S-14.6 Arbitration of Claims and Disputes For purposes of this section, a claim for adjustment in compensation shall mean an aggregate of operative facts which give rise to the rights which the Contractor seeks to enforce. Stated another way, a claim is the event, transaction, or set of facts that give rise to a claim for compensation. Any Contractor having a claim in excess of $75,000.00 may waive or abandon the dollar amount in excess of $75,000.00 so as to bring the claim within the scope of this section.

(b) For slipform concrete paving utilizing a dedicated portable batching plant, perform a validation strength-maturity test once every fifteen (15) calendar days during plant production. (c) For all other concrete, if the maturity curve was developed greater than thirty (30) calendar days before the start of construction or has not been validated for thirty (30) calendar days, perform a validation strength-maturity test on the first day of concrete placement. The Engineer will allow a single validation strength- maturity test fabricated at the concrete plant to validate a maturity curve used on multiple projects. Validation strength-maturity tests fabricated at the project site only validate the maturity curve for that project. (3) The Contractor or representative is responsible for providing the curing environment for the specimens in accordance with the “Estimating Concrete Strength by the Maturity Method” procedure available from the MnDOT Concrete Engineering website. (4) Perform the validation testing as close as practically possible to the maturity value determined to represent the opening, loading or form removal strength criteria. Record the results of the tests on the Concrete Maturity-Strength Validation form and provide to the Engineer within 24 hours of the test completion. (5) If a specimen is obviously defective (i.e., out of round, not square, damaged due to handling), discard the specimen. If an individual specimen is greater than 10 percent for cylinders or 15 percent for beams outside the average of three specimens, consider the specimen defective and discard. When two of the specimens are defective, evaluate a new batch, unless additional acceptable specimens are available.

The Engineer may direct additional validation testing as necessary.

The Engineer will review the validation strength-maturity test results and determine if the validation testing confirms the maturity curve in accordance with Table 2461-22.

S-52 (3302) DOWEL BAR NEW WRITE-UP 04/09/20 SP2018-259 MnDOT 3302 is hereby deleted and replaced with the following:

3302.1 SCOPE Provide dowel bars for use in Portland cement concrete pavements and other concrete applications as shown on the plans.

3302.2 REQUIREMENTS

A Epoxy Coated Steel Dowel Bars Provide Grade 40 or Grade 60 steel dowel bars meeting the requirements of AASHTO M 31.

Epoxy coat the steel dowel bars in accordance with AASHTO M254 and as modified: (1) Apply epoxy coating in a fusion bonded epoxy coating plant certified by the CRSI or another organization approved by the Materials Engineer. (2) Apply 7-13 mils epoxy coating thickness. (3) Do not epoxy coat the ends of the dowel bars unless required by the Manufacturer.

If cutting dowel bars to length by shearing, immediately repair all damaged epoxy coating and verify dowel bars have not exceeded the maximum deformation limits. Ensure that sheared dowel bars are not more than 0.04 in out of round, and that such damage does not extend more than 0.40 in from the end of the bar.

B Tubular Dowel Bars Provide welded carbon and alloy steel tubular dowel bar meeting the requirements of ASTM 513 and Table 3302-1.

Table 3302-1 Tubular Dowel Bar Requirements Specified Dowel Bar Required Tubular Dowel Bar Required Tubular Dowel Bar Diameter Outside Diameter Wall Thickness 1.25 in 1.3125 in or 1.375 in 0.120 in 1.50 in 1.625 in 0.120 in

Provide a galvanized coating providing a minimum 20 year life. Cap the ends of the tubular dowel bar in a way to prevent intrusion of concrete or other materials.

Galvanize the exterior and interior of the tubular steel dowel bars using G90 coverage zinc galvanized coating.

Epoxy coat the exterior of the galvanized tubular dowel bars in accordance with ASTM A1078 Type 2 coating (ASTM A934 Annex A1) and as modified: (1) Apply epoxy coating in a fusion bonded epoxy coating plant certified by the CRSI or another organization approved by the Materials Engineer. (2) Epoxy coating of the entire dowel bar assembly is not required. (3) Do not epoxy coat the ends of the dowel bars unless required by the Manufacturer.

C Bond Breaker Material Provide bond breaker material listed on the Approved/Qualified Products List.

Prior to delivery to the project site, coat the entire dowel bar assembly or dowel bar bundles with a bond breaker material in accordance with the Manufacturer’s recommendations. Appendix C

SPECIAL PROVISIONS - SP2018 BOOK Wash Co Div S – Rev 4 CSAH 16 Median Repair Page 73

D Certification of Dowel Bars Ensure the manufacturer’s plant quality control office maintains documentation containing the data required by certification, including test data and measurements taken at times and locations as required by the CRSI, the Materials Engineer, or both.

Include the following standardized statement with delivery invoices: “(insert company name) certifies that the dowel bars and basket assemblies are coated with a bond breaker material and meet the requirements of MnDOT Specification 3302.”

E Storage and Protection of Dowel Bars Do not store dowel bars in a manner that will cause, induce, or accelerate corrosion or contamination of the metal at any time. Locate timbers (dunnage) on the ground to support the bundles and keep them free of contamination.

Protect coated dowel bars before handling or shipping to prevent damage to the coating. Pad bundling bands and lift bundles using an OSHA-approved spreader bar, multiple supports, or platform bridge to prevent bar-to-bar abrasion from sags in the bar bundle. Do not drag or drop bars or bundles. Support bars or bundles in transit to prevent damage to the coating.

Store materials at the project site to allow the Engineer to visually inspect and check the various types of reinforcement for conformance to the dimensions as shown on the plans. Store bars of the same type together. Identify dowel bars with tags bearing the identification symbols as shown on the plans.

If the epoxy-coated steel is incorporated into the Project and is exposed to the weather or stored exposed to the weather for more than 60 calendar days, cover the steel to protect the material from sunlight, salt-spray and weather exposure. Provide for air circulation around the covered steel to minimize condensation under the protective covering.

3302.3 SAMPLING AND TESTING Sample and test dowel bars and dowel basket assemblies in accordance with the Schedule of Materials Control. The Department will visually inspect the bond breaker material coating on the dowel bars. Appendix C

Notice of truck rental rate certification and effective date

The Department of Labor and Industry (DLI) temporary commissioner has certified the minimum truck rental rates for state-funded highway projects effective Dec. 21, 2020. This certification follows the publication of the Notice of Truck Rental Rate Determination in the State Register on Nov. 30, 2020, and the informal conference held pursuant to Minnesota Rules, part 5200.1105, Dec. 11, 2020.

According to Minnesota Rules, part 5200.1105, the purpose of the informal conference was for DLI to obtain further input regarding the determined rates prior to the certification. No written input regarding the determination was received by DLI prior to the informal conference.

The truck rental rate is determined for each equipment type by adding the average hourly cost of operating the vehicle to the certified prevailing wage rate for the driver. The average hourly operating costs are determined by voluntary survey of truck owner operators, trucking contractors and trucking firms.

The determination of the minimum truck rental rates by region are as follows.

(6) The contractor or related entity is not currently suspended or debarred by the federal government or the state of Minnesota or any of its departments, commissions, agencies, or political subdivisions that have authority to debar a contractor; and (7) All subcontractors and motor carriers that the contractor intends to use to perform project work have verified to the contractor through a signed statement under oath by an owner or officer that they meet the minimum criteria listed in clauses (1) to (6).

Minn. Stat. § 16C.285, Subd. 5. SUBCONTRACTOR VERIFICATION. A prime contractor or subcontractor shall include in its verification of compliance under subdivision 4 a list of all of its first-tier subcontractors that it intends to retain for work on the project. Prior to execution of a construction contract, and as a condition precedent to the execution of a construction contract, the apparent successful prime contractor shall submit to the contracting authority a supplemental verification under oath confirming compliance with subdivision 3, clause (7). Each contractor or subcontractor shall obtain from all subcontractors with which it will have a direct contractual relationship a signed statement under oath by an owner or officer verifying that they meet all of the minimum criteria in subdivision 3 prior to execution of a construction contract with each subcontractor. If a prime contractor or any subcontractor retains additional subcontractors on the project after submitting its verification of compliance, the prime contractor or subcontractor shall obtain verifications of compliance from each additional subcontractor with which it has a direct contractual relationship and shall submit a supplemental verification confirming compliance with subdivision 3, clause (7), within 14 days of retaining the additional subcontractors. A prime contractor shall submit to the contracting authority upon request copies of the signed verifications of compliance from all subcontractors of any tier pursuant to subdivision 3, clause (7). A prime contractor and subcontractors shall not be responsible for the false statements of any subcontractor with which they do not have a direct contractual relationship. A prime contractor and subcontractors shall be responsible for false statements by their first-tier subcontractors with which they have a direct contractual relationship only if they accept the verification of compliance with actual knowledge that it contains a false statement. Subd. 5a. Motor carrier verification. A prime contractor or subcontractor shall obtain annually from all motor carriers with which it will have a direct contractual relationship a signed statement under oath by an owner or officer verifying that they meet all of the minimum criteria in subdivision 3 prior to execution of a construction contract with each motor carrier. A prime contractor or subcontractor shall require each such motor carrier to provide it with immediate written notification in the event that the motor carrier no longer meets one or more of the minimum criteria in subdivision 3 after submitting its annual verification. A motor carrier shall be ineligible to perform work on a project covered by this section if it does not meet all the minimum criteria in subdivision 3. Upon request, a prime contractor or subcontractor shall submit to the contracting authority the signed verifications of compliance from all motor carriers providing for-hire transportation of materials, equipment, or supplies for a project.

Revised 2/3/2021 Page 2 of 5 Minn. Stat. § 16C.285, Subd. 4. VERIFICATION OF COMPLIANCE.

A contractor responding to a solicitation document of a contracting authority shall submit to the contracting authority a signed statement under oath by an owner or officer verifying compliance with each of the minimum criteria in subdivision 3, with the exception of clause (7), at the time that it responds to the solicitation document. A contracting authority may accept a signed statement under oath as sufficient to demonstrate that a contractor is a responsible contractor and shall not be held liable for awarding a contract in reasonable reliance on that statement. A prime contractor, subcontractor, or motor carrier that fails to verify compliance with any one of the required minimum criteria or makes a false statement under oath in a verification of compliance shall be ineligible to be awarded a construction contract on the project for which the verification was submitted. A false statement under oath verifying compliance with any of the minimum criteria may result in termination of a construction contract that has already been awarded to a prime contractor or subcontractor or motor carrier that submits a false statement. A contracting authority shall not be liable for declining to award a contract or terminating a contract based on a reasonable determination that the contractor failed to verify compliance with the minimum criteria or falsely stated that it meets the minimum criteria. A verification of compliance need not be notarized. An electronic verification of compliance made and submitted as part of an electronic bid shall be an acceptable verification of compliance under this section provided that it contains an electronic signature as defined in section 325L.02, paragraph (h).
