ATTACHMENT H SPECIAL PROVISION CONTRACTOR CONTRACTUAL REQUIREMENTS TITLE VI ASSURANCES TxDOT CSJ NO.: 0318ADDON During the performance of this Agreement, the contractor, for himself,
its ass1gnees and successors in interest (hereinafter referred to as the "contractor" agrees as follows: !. Compliance with Regulations. The contractor shall comply with the regulations
relative to nondiscrimination in federally assisted programs of the Department of Transportation (hereinafter "DOT") Title 49, Code of Federal Regulations, Part 21, as they may be amended
from time to time, (hereinafter referred to as the Regulations), which are herein incorporated by reference and made a part of this Agreement. 2. Nondiscrimination. The contractor, with
regard to the work performed by it during the Agreement, shall not discriminate on the grounds of race, color, or national origin in the selection and retention of subcontractors, including
procurement of materials and leases of equipment. The contractor shall not participate either directly or indirectly in the discrimination prohibited by section 2!.5 of the Regulations,
including employment practices when the Agreement covers a program set forth in Appendix B of the Regulations. 3. Solicitations for Subcontractors, Including Procurement of Materials
and Equipment. In all solicitations either by competitive bidding or negotiation made by contractor for work to be performed under a subcontract, including procurement of materials or
leases of equipment, each potential subcontractor or supplier shall be notified by the contractor of the contractor's obligations under this Agreement and the Regulations relative to
nondiscrimination on the grounds of race, color, or national origin. 4. Information and Reports. The contractor shall provide all information and reports required by the Regulations
or directives issued pursuant thereto and shall permit access to its books, records, accounts, other sources of information, and its facilities, as may be determined by the Agent or
the Federal Aviation Administration (FAA) to be pertinent to ascertain compliance with such Regulations, orders, and instructions. Where any information required of a contractor is in

ATTACHMENT I DISADVANTAGED BUSINESS ENTERPRISE (DBE) ASSURANCES TxDOT CSJ NO.: 0318ADDON 1. POLICY. It is the policy of the United States Department of Transportation (DOT) that Disadvantaged
Business Enterprises (DBE), as defined in 49 CFR Part 26, Subpart A, be given the opportunity to compete fairly for contracts and subcontracts financed in whole or in part with Federal
funds under this Agreement. Consequently, the DBE requirements of 49 CFR Part 26 apply to this Agreement. 2. DBE OBLIGATIONS. The contractor will offer DBEs, as defined in 49 CFR Part
26, Subpart A, the opportunity to compete fairly for contracts and subcontracts fmanced in whole or in part with Federal funds provided under this Agreement. In this regard, all contractors
will make a good faith effort in accordance with 49 CFR Part 26 to meet the contract DBE goal. Contractors shall not discriminate on the basis of race, color, ·national origin, or sex
in the award and performance of DOT -assisted contracts. The Contractor shall carry out out applicable requirements of 49 CFR Part 26 in the award and administration of DOT assisted
contracts. The requirements of this provision shall be physically included in any subcontract. 3. PROJECT DBE PARTICIPATION GOAL AND GOOD FAITH EFFORT. The bidder/proposer shall make
good faith efforts, as defined in Appendix A of 49 CFR Part 26, Regulations of the Office of the Secretary of Transportation, to subcontract ..1L percent of the dollar value of the prime
contract to DBEs. A bidder for this solicitation that qualifies as a DBE, may receive credit toward the DBE goal for work perfonned by his/her own forces and work subcontracted to DBEs.
The DBE bidder must report any subcontracts to non-DBEs. The apparent successful competitor will be required to submit information concerning the DBE(s) that will participate in the
contract. Eligible DBEs are finns certified as such by the Department in accordance with 49 CFR Part 26. The information will include: (1) the name and address of each DBE; (2) a description
description of the work to be performed by each named firm; and (3) the dollar value of the work of the contract. If the bidder fails to achieve the contract goal stated herein, it will
be required to provide documentation demonstrating that it made good faith efforts in attempting to do so. A bid that fails to meet these requirements will be considered nonresponsive.
If the Director of Aviation detennines that the apparent successful competitor has failed to meet the good faith effort requirements, they will be given an opportunity for reconsideration
by the Director of the Construction Division. 4. Counting DBE Participation Toward Meeting the Goals. The Texas Department of Transportation through the Division of Aviation, hereinafter
called the "Agent," will count DBE participation toward the goals in accordance with the guidelines outlined below. a. Once a firm is determined to be an eligible DBE under 49 CFR Part
26, the total amount paid to the DBE for work perfonned with his/her own forces is counted toward the DBE goal. When a DBE subcontracts part of the work of its contract to another firm,
the value of the subcontracted work may be counted toward DBE goals only if the subcontractor is itself a DBE. Work that a DBE subcontracts to a non-DBE firm does not count toward DBE
goals. An eligible DBE is defined for this program as one that is currently certified by the Texas Department of [.J 
Transportation. b. The Agent and its contractors will count toward the DBE goals a portion of the total dollar value of a contract with a certified DBE joint venture equal to the distinct,
clearly defined portion of the work of the contract performed by the DBE. c. Only expenditures to the DBE that performs a commercially useful function in the work of a contract will
be counted toward the DBE goals. A DBE is considered to perform a commercially useful function when it is responsible for execution of the work of the contract and carrying out its responsibilities
by actually performing, managing, and supervising the work involved. To determine whether a DBE is performing a commercially useful function, the Agent and its contractors will evaluate
the amount of work subcontracted, industry practices, and other relevant factors. When a DBE is presumed not to be performing a commercially useful function, the DBE may present evidence
to rebut this presumption. d. Consistent with normal industry practices, a DBE may enter into subcontracts. If a DBE contractor subcontracts a significantly greater portion of the work
of the contract than would be expected on the basis of normal industry practices, the DBE shall be presumed not to be performing a commercially useful function. The DBE may present evidence
to the Agent to rebut this presumption. e. The Agent and its contractors will count toward the DBE goals 60 percent of expenditures for materials and supplies required under a contract
and obtained from a DBE regular dealer, and 100 percent of such expenditures obtained from a DBE manufacturer. f. For purposes of this DBE program, a manufacturer is a firm that operates
or maintains a factory or establishment that produces on the premises the materials, supplies, articles or equipment required under the contract and of the general character described
by the specifications. Brokers, packagers, manufacturers' representatives or persons who arrange or expedite transactions shall not be regarded as manufacturers. g. For purposes of this
DBE program, a regular dealer is a firm that owns, operates, or maintains a store, warehouse, or other establishment in which the materials, supplies, articles or equipment of the general
character described by the specifications and required under the contract are bought, kept in stock, and regularly sold or leased to the public in the usual course of business. To be
a regular dealer, the firm must be an established regular business that engages in, as its principal business, and in it~ own name, the purchase and sale of the products in question.
A regular dealer in such bulk items as steel, cement, gravel, stone and petroleum products need not keep such products in stock, if it owns or operates distribution equipment for the
product. Brokers, packagers, manufacturers' representatives or other persons who arrange or expedite transactions shall not be regarded as regular dealers. Any supplementing of regular
dealers own distribution equipment shall be by a long-term lease Agreement and not on an adhoc or contractby-contract basis. h. The Agent and its contractors may count toward the DBE
goals the following expenditures to DBE firms that are not manufacturers or regular dealers provided that the fee or 1-2 
commission is determined by the Agent to be reasonable and not excessive as compared with fees customarily allowed for similar services: ' · (1) The fees or commissions charged by a
DBE for providing a bona fide service, such as professional, technical, consultant or managerial services, and assistance in the procurement of materials or supplies required for performance
of the contract, provided that the fee or commission is determined by the Agent to be reasonable and not excessive as compared with fees customarily allowed for similar services. (2)
The fees charged for delivery of material and supplies required on a job site (but not the cost of the materials and supplies themselves) when the hauler, trucker, or delivery service
is not also the manufacturer or a regular dealer in the materials and supplies. (3) The fees or commission charged for providing any bonds or insurance specifically required for the
performance of the contract 5. CONDITIONAL AWARD. If the successful bidder for a federal-aid contract is determined to be acceptable, the Agent will conditionally award the contract
The condition of the award is that within 14 days after the date of the award, the bidder must furnish to the Agent names and addresses ofthe DBE subcontractors that are proposed to
be used, a description of the work each subcontractor is to perform, the dollar value of each proposed subcontract, and a tentative Agreement for each DBE firm submitted, signed by an
officer of the contractor and an officer of the proposed DBE firm. A contractor who does not meet the contract goal, in whole or in part, must submit within the 14 days, documentation
showing the steps taken to obtain DBE participation ("Good Faith Effort"). Such documentation is to be submitted directly to the Agent's Grant Administrator. The Agent's Grant Administrator
will evaluate the contractor's documented efforts and will determine whether or not they constitute compliance with the contract DBE requirements and are acceptable. Should the bidder
to whom the contract is conditionally awarded refuse, neglect or fail to meet the goals or furnish acceptable documentation, the bid bond filed with the bid may become the property of
the State, not as a penalty, but as liquidated damages to the Agent 6. CONDITIONAL ACCEPTANCE OF PROPOSAL. If the successful proposer for a federal-aid professional services contract
is determined to be acceptable, the Agent will conditionally accept the proposaL The condition of the acceptance is that prior to the execution of a professional services contra<;t,
the proposer must furnish to the Agent names and addresses of the DBE subcontractors that are intended to be used, a description of the work each subcontractor is to perform, the dollar
value of each proposed subcontract, and a tentative Agreement for each DBE firm submitted, signed by an officer of the contractor and an officer of the proposed DBE firm. A professional
service provider who does not meet the contract goal, in whole or in part, must submit prior to execution of the contract, documentation showing the good faith efforts made to meet the
DBE goaL Such documentation is to be submitted directly to the Aviation Division. TxDOT's Aviation Division will evaluate the professional service provider's documented efforts and will
determine 1-3 
whether or not they constitute compliance with the contract DBE requirements and are acceptable. If the Director of the Aviation Division determines that the professional 'service provider
has failed to meet the good faith effort requirements, the professional service provider will be given an opportunity for reconsideration by the Director of the Construction Division.
Should the professional service provider whose proposal has been conditionally accepted refused, neglect or fail to make a good faith effort to meet the goals or furnish acceptable documentation,
the Agent may then conditionally accept the proposal of the second selected proposer. 7. REQUIRED REPORTING OF DBE PARTICIPATION. The contractor shall submit on a monthly basis reports
of DBE participation to meet the goal and for race-neutral DBE participation, and submit a final report on the completion of the project. Only actual payments made to DBEs are to be
reported. Reports for race-neutral DBE participation on contracts with no DBE goal are are required. 8. SANCTIONS FOR NONCOMPLIANCE. In the event of the contractor's noncompliance with
the DBE requirements of this contract, the Agent may impose one or more of the following contract sanctions : a. cancellation, termination or suspension of the contract, in whole or
in part, and/or b. withholding of payments to the contractor under the contract until the contractor complies, and/or c. other remedies as FAA or the Agent deems appropriate. 1-4
