INTRODUCTION

The North Texas Tollway Authority (NTTA) invites experienced and qualified companies to submit bids (each, a “Bid”) to provide the NTTA Generator Preventative Maintenance and repair (the “Project”) to NTTA in accordance with the terms of this RFB. A company that seeks to be awarded the contract (“Contract”) for the Project under this RFB will be referred to as a Bidder.

This RFB includes the Scope of Work and other requirements for the Project that NTTA has determined are pertinent to the preparation of a Bid. Regardless of whether deliverables under this procurement comprise goods, services, or both, all deliverables to be provided under the Contract will be referred to in this RFB as “goods and services.”

NTTA intends to award a Contract to the lowest responsible Bidder. The form of the Contract NTTA intends to utilize for this procurement is included with this RFB. However, NTTA reserves the right to modify the attached form of the Contract as NTTA deems necessary or advisable for particular requirements of the Project.

Background NTTA is a regional tollway authority governed by Chapter 366 of the Texas Transportation Code authorized to acquire, construct, maintain, repair, and operate turnpike projects in the North Texas region. NTTA serves its member counties of Collin, Dallas, Denton, and Tarrant and is responsible for the NTTA System of toll roads in the region, including Dallas North Tollway, President George Bush Turnpike, Sam Rayburn Tollway, SH 360, Addison Airport Toll Tunnel, Lewisville Lake Toll Bridge, Chisholm Trail Parkway, and Mountain Creek Lake Bridge. NTTA is governed by a nine-member board of directors (Board) with two members appointed by each of the four NTTA member counties. A ninth member is appointed by the Governor of Texas. For more information, a list of the individuals that currently serve on the NTTA Board of Directors is provided on NTTA’s website at www.ntta.org.

NTTA Mission Statement and Values To provide a safe and reliable toll road system, increase value and mobility options for our customers, operate the Authority in a businesslike manner, protect our bondholders, and partner to meet our region's growing need for transportation infrastructure.

GENERAL INFORMATION

Contract Term The Contract will become effective upon its final execution by both parties and satisfaction of the requirements of Section 2252.908 of the Texas Government Code and all other applicable legal requirements. The Term of the Contract is Three (3) years.

http://www.ntta.org/

5 Rev. January 2026

Property of North Texas Tollway Authority Subject to the provisions of this RFB concerning Confidential Information, all written and electronic correspondence, appendices, photographs, reports, printed material, tapes, disks, designs, and other graphic and visual aids submitted to NTTA during this procurement will become the property of NTTA upon delivery to NTTA and will not be returned to the submitting parties.

Award Limitations None.

Language, Words Used Interchangeably The words “shall,” “must,” and “will” are equivalent in this RFB and indicate a mandatory requirement or condition, the material deviation from which will not be waived by NTTA. A deviation is material if, at the sole discretion of NTTA, the deficient response is not in substantial accord with this RFB’s mandatory condition requirements. The words “should” and “may” are equivalent in the RFB and indicate very desirable conditions or requirements but are permissive in nature. Deviation from, or omission of, such a desirable condition or requirement will not in and of itself cause automatic rejection of a Bid but may result in the Bid being considered as not in the best interest of NTTA.

INSTRUCTIONS TO BIDDERS

Confidentiality and Non-Disclosure Statement Each Bidder agrees that any information accessed or gained by it in the course of the procurement under this RFB or, if applicable, in performance of duties under the Contract will be maintained in confidence and will not be released, discussed, or made known to any party or parties for any reason whatsoever, except as required to perform the duties required or where disclosure is required by law or mandated by a court of law.

Each Bidder must execute a “Confidentiality and Non-Disclosure Statement” and return it to NTTA. The Confidentiality and Non-Disclosure Statement is located under the REQUIRED FORMS section of this RFB (Appendix C).

Pre-Bid Conference

A pre-bid conference will be conducted for this solicitation and, it will be open to the public to attend. The purpose of the conference is to review the scope and requirements of this RFB and allow interested Bidders to ask questions.

At least one (1) representative from each firm that intends to submit a Bid as a Bidder is encouraged to attend by calling Phone# +1 496-214-9499 Conf.ID: 130 946 594# to join the pre-bid conference Microsoft Teams Meeting.

Registration, Acknowledgment, and Addendums

6 Rev. January 2026

A Bidder must complete vendor registration and acknowledge this RFB through NTTA Marketplace (www.nttamarketplace.org) in order to participate in this solicitation. Acknowledgement ensures that the Bidder receives notifications regarding the solicitation. This includes, but is not limited to, notifications advising Bidder of addendums, amendments, and clarifications to this RFB (each, an “Addendum”). Bidders should acknowledge each Addendum, if any, to this RFB.

If NTTA issues an Addendum to this RFB (whether a change to the solicitation specifications or any other modification) after a Bid has already been submitted, the Bidder, at its option, may access, modify, and resubmit its Bid to take such Addendum into account. Any submitted sealed Bid may be updated prior to the closing date/time for submission of Bids as set out in this RFB. A Bidder’s failure to update and resubmit a Bid following the issuance of an Addendum will signify the Bidder’s election to leave its Bid unmodified.

Inquiries It is the Bidder’s responsibility to obtain clarification of any information contained herein. Questions regarding any aspect of this procurement are to be submitted via the solicitation’s Q&A section on NTTA Marketplace no later than the Bid Question Deadline shown on the cover page of this RFB. All clarifications and answers to questions will be addressed in writing and posted online as an addendum to this RFB.

Statement(s) regarding the meaning or intent of the contents of this RFB by any person other than the Solicitation Contact Person listed on the cover page of this RFB are unauthorized, invalid, and cannot be relied upon.

The Solicitation Number must be referenced in all correspondence pertaining to this solicitation.

Except for any meeting(s) specifically authorized by the Solicitation Contact Person (or designee) as part of the Bid evaluation during the solicitation process, there must be no contact regarding this RFB between a Bidder’s owners, officers, directors, employees, agents, contractors, subcontractors, or other parties acting on a Bidder’s behalf and any NTTA Board member, employee, agent, or consultant, other than the Solicitation Contact Person.

Notwithstanding this prohibition on contact, Bidder may reach out to NTTA’s Director of Procurement Services regarding a solicitation or any questions and/or clarifications about Business Development and Opportunities Department (BDOD) Small Business Program requirements for a solicitation. A Bidder’s failure to comply with this provision will be grounds for NTTA’s disqualification of a Bidder and rejection of its Bid.

SUBMITTAL OF BIDS

To be considered for this procurement, each Bidder must include with their Bid Sheet all required documents and UPLOAD them on NTTA Marketplace (www.nttamarketplace.org), no later than the date and time identified on the cover page as the “Bid Due Date”.

A. Important Submittal Requirements

NTTA is not responsible for Bids received but not clearly marked. It will be the responsibility of each Bidder to upload its Bid Sheet to NTTA at the above listed website before or by Bid Due Date. Late Bids will not be accepted.

NTTA is not responsible for delays caused by any other means of delivery employed by the Bidder. Similarly, NTTA is not responsible for, and will not open, any Bids received later than the date and time indicated above.

NTTA reserves the right, in its sole discretion, to waive any technicality in a response to this RFB, provided such action is in the best interests of NTTA.

NTTA reserves the right, in its sole discretion, to interrupt, postpone, delay, or cancel this solicitation at any time.

B. Important Electronic Marketplace Vendor Response Guide

To be considered a responsive and responsible Bidder, it is important to read and follow instructions listed in the electronic “Marketplace Vendor Response Guide” located on NTTA Marketplace (www.nttamarketplace.org). The following is an important task to remember:

NOTE:

Lowest Responsible Bidder Under NTTA’s Procurement Policy and this RFB, the “lowest responsible Bidder” is the Bidder who submits a Bid to provide the requested goods and services at a cost that is lower than all other Bids from responsible Bidders and which meets other requirements of the NTTA.

In determining the lowest responsible bidder, NTTA may consider: (a) the purchase price; (b) the reputation of the Bidder and of the Bidder’s goods or services; (c) the quality of the Bidder’s goods or services; (d) the extent to which the goods or services meet NTTA’s needs; (e) the Bidder’s past relationship with NTTA; (f) the total long-term cost to NTTA to acquire the Bidder’s goods or services; and (g) any relevant criteria specifically listed in this RFB. Without limiting the foregoing, any Bidder that NTTA determines is non-responsible or non-responsive will not be deemed the lowest responsible Bidder.

When responding, be certain to check the Confidential check box for each uploaded document. You must do so for each document that you would like to designate as confidential. If you fail to check this box, such document(s) will be viewable by the general public.

8 Rev. January 2026

Determination of Non-Responsible Bidder NTTA will not consider the Bid of a Bidder NTTA determines to be non-responsible.

NTTA may deem a Bidder non-responsible if:

1. NTTA has reason to believe collusion exists among the Bidder and other Bidders.

2. The Bidder, any subcontractor, supplier, or the surety on any bond given, or to be given by the Bidder, is in litigation with NTTA or with Collin, Dallas, Denton, Tarrant, Ellis, or Johnson counties or any cities in those counties (collectively, “Service-Area Entities”), or such litigation is contemplated or imminent, in the sole opinion of NTTA.

3. The Bidder is in default on any existing contract with a Service-Area Entity or defaulted on a previous contract with a Service-Area Entity.

4. The Bidder or a proposed subcontractor thereof has failed to disclose a potential conflict of interest or is discovered to have a conflict of interest, by law or policy, as determined by NTTA.

5. The Bidder, a proposed subcontractor thereof, or an individual officer or owner of the Bidders or company comprising a partner, member, or affiliate of the Bidder or any proposed subcontractor of a Bidder is under criminal indictment or been convicted of a criminal offense.

6. The Bidder or any firm comprising a partner, member, or affiliate of the Bidder or any proposed subcontractor of a Bidder (collectively, with Bidder, the Bidder Team) has received compensation from NTTA to participate in the preparation of this RFB, including, but not limited to, any component of the Scope of Work.

7. Any employee, consultant, or agent of any member of the Bidder’s Team participated in the preparation of this RFB, including, but not limited to, any component of the Scope of Work (any such person being referred to as a Screened Person).

a. However, if (i) no member of the Bidder’s Team received compensation from NTTA to participate in the preparation of this RFB (refer to item 6 above), and (ii) NTTA is promptly informed of a Screened Person’s employment with a member of a Bidder’s Team, a Bidder will not be deemed non-responsible if the Bidder demonstrates to NTTA’s satisfaction that a screening procedure exists to ensure that at all times before NTTA’s execution of the Contract (a) the Screened Person has not participated in the preparation of the Bid and (b) no person participating in the preparation of the Bid has discussed with or received from the Screened Person information about this RFB, including, but not limited to, any component of the Scope of Work.

b. Bidder must inform NTTA in writing promptly after it receives this RFB, of any Screened Person’s employment with a member of the Bidder’s Team. If

9 Rev. January 2026 at a later date a Screened Person is employed by a member of the Bidder’s Team, written notice of such employment must be given to NTTA promptly upon the Screened Person’s employment. Failure to provide such written notice may result in Bidder being deemed Non-Responsible.

8. The Bidder is not eligible to be awarded the Contract under applicable law or NTTA’s Procurement Policy, which may be found online at NTTA’s website, ntta.org (currently under “Policies” in the “Who We Are” section).

Determination of Non-Responsive Bidder NTTA may disqualify a Bid as non-responsive and it shall not be considered for reasons including but not limited to the following:

1. All elements of the Bid required under this RFB are not included or all requirements for submission described under “Submission of Bids” are not strictly followed.

2. The Bid was received after the time limit for receiving Bids.

3. The Bid is not signed.

4. Bidder does not register with NTTA Marketplace or fails to acknowledge this solicitation or any Addendums.

Rejection of Bids Procurement Services will automatically reject any Bid that is submitted after the Bid Due Date listed on the cover page of this RFB, and return it unopened. Until a Contract is executed, NTTA reserves the right to reject any or all Bids, to waive technicalities, to re-advertise, to decline to proceed or to otherwise proceed with this procurement by other method(s) allowed by law and in the best interest of NTTA.

Withdrawing a Bid Bidder, by submitting a Bid, warrants and guarantees that the Bid has been carefully reviewed and checked and that it is in all respects true, accurate, and free of mistakes.

However, a Bidder has a right to withdraw a Bid prior to the Bid Due Date.

To withdraw its Bid, Bidder must submit a request to withdraw its Bid in writing via email to the Director of Procurement Services, Danielle Thompson, at dthompson@ntta.org. The written request to withdraw a Bid must state the reason for the withdrawal request. A Bid for which withdrawal is properly requested prior to Bid Due Date will be returned to the Bidder unopened.

A Bidder may not withdraw its Bid after the Bid Due Date without NTTA’s express written consent. Bidders acknowledge that for a Bid withdrawn after the Bid Due Date,

(1) NTTA may pursue any security, such as a bid bond, given by the Bidder for such withdrawn Bid and (2) the withdrawn Bid will not be eligible to be reinstated for this

RFB.

10 Rev. January 2026

BID AWARD

The Bidder that NTTA Procurement Services identifies as the lowest responsible Bidder will be the “apparent low bidder,” and NTTA will submit the Contract to the apparent low bidder.

When the apparent low bidder unconditionally agrees to execute, deliver, and perform the Contract and submits or has unconditionally agreed to submit (a) all required bonds, insurance, and other items required under this RFB and (b) the Contract, the Contract will then be approved and signed by appropriate parties.

The successful Bidder will assume total responsibility for all obligations under the Contract.

Further, NTTA will consider the successful Bidder to be the sole point of contact with regard to contractual matters, including payment of all charges resulting from the Contract. No subcontractor will be paid directly by NTTA. The Bidder will be solely responsible for the success of any portion of and the entire Project under this RFB.

Unless expressly stated otherwise, all Bids shall be considered valid and in effect until the Bid evaluation, award, and Contract execution process is completed (estimated 60 – 180 days).

TERMS AND CONDITIONS

Acceptance of Evaluation and Selection Procedures Each Bidder represents that it (1) has carefully examined this RFB, including all attachments hereto, and (2) does not object to the procedures and processes as described in this RFB, for evaluating and selecting the lowest responsible Bidder for this Procurement or for the award and execution of the Contract. No exceptions to the terms and conditions of the Contract will be accepted by NTTA. Any exceptions submitted by Bidder with its Bid will be disregarded, and NTTA will consider Bidder’s Bid as submitted for use with the form Contract attached hereto without any changes.

Procurement Policy, RFB, and Applicable Law This RFB and the procurement requirements and procedures described in this RFB are subject to applicable law and NTTA’s Policy Regarding the Procurement of Goods and Services and Disposition of Personal Property (Procurement Policy), which NTTA adopted under Section 366.033(j) of the Texas Transportation Code. A copy of the Procurement Policy is available on NTTA’s website, ntta.org (currently under “Policies” in the “Who We Are” section).

Each Bidder agrees to be bound by the terms, conditions, agreements, and requirements of applicable law, the Procurement Policy and this RFB, including, but not limited to, NTTA’s procurement protest procedures. A Bidder’s submission of a Bid under this RFB will further signify such agreement.

Confidential Information and Texas Public Information Act Information included in a Bid is subject to the Texas Public Information Act, Chapter 552 of the Texas Government Code (TPIA). Information is not exempt as confidential under TPIA simply because the party submitting the information

11 Rev. January 2026 anticipates or requests that it be kept confidential. Accordingly, a Bidder whose Bid includes information that the Bidder believes in good faith to be confidential or proprietary information or to contain trade secrets of Bidder (Confidential Information) must mark such information accordingly. This marking must be explicit as to the designated information. The Bidder will hold NTTA harmless from any claims arising from the release of Confidential Information not clearly designated as such by the Respondent. Designation does not guarantee the non-release of Confidential Information under the TPIA or as otherwise required by law, but does provide NTTA with a means to review the issues thoroughly and, if justified, request an opinion by the Attorney General’s office before releasing Confidential Information requested under the TPIA. If NTTA receives a request for Confidential Information, NTTA shall notify Bidder in writing in accordance with the requirements of the TPIA and will, if reasonably and timely requested by Bidder, ask for a decision from the Open Records Division of the Office of the Attorney General of the State of Texas regarding whether the information may be excepted from disclosure under the TPIA.

In such event, Bidder authorizes NTTA to submit any information contained in the Bid, including information the Bidder has labeled as being Confidential Information, to the Office of the Attorney General. Bidder bears the burden of making the appropriate showing(s) to the satisfaction of the Attorney General’s Office.

NTTA, its directors, officers, employees, agents, and attorneys are not liable for any disclosure of any information submitted in a response to this RFB. By submitting a Bid, the Bidder waives any claim against, and releases from liability, NTTA, its directors, officers, employees, agents, and attorneys with respect to disclosure of any information included in the Bid, including information labeled as Confidential Information.

Award Non-Exclusive NTTA reserves the right to award a contract to more than one Bidder based on NTTA’s consideration of its operational needs. There will be no minimum amount of services awarded any successful Bidder under this RFB. A successful Bidder will assume total responsibility for all deliverables awarded to it whether a subcontractor or other third party produces them in whole or in part. NTTA considers a successful Bidder to be the sole point of contact with regard to contractual matters including payment of all charges resulting from the Contract. A successful Bidder will be fully responsible for any default by a subcontract just as if the successful Bidder itself had defaulted. No subcontractor will be paid directly by NTTA. A successful Bidder will be solely responsible for the performance of the portion of the entire Project awarded to it under this RFB.

Third-Party “Remit To” If a Bidder has a third-party “remit-to” company for payment that information must appear on the Bidder’s Bid to this RFB. NTTA will not be liable for payments to Bidder sent to the third party designated on the Bidder’s Bid.

Tax Exempt Authority NTTA is a tax-exempt entity under Sections 151.309, et seq., of the Texas Tax Code.

12 Rev. January 2026

Incurring Costs All costs incurred by a Bidder in preparing the Bid or otherwise in responding to this RFB will be wholly the responsibility of the Bidder. NTTA will not reimburse any Bidders for costs incurred as it relates to participating in the procurement process for this solicitation.

Disclosure of Interested Parties Section 2252.908 of the Texas Government Code states that state agencies and other governmental entities, such as NTTA, may not enter into certain contracts with a business entity (defined as a “Contractor” in that section) unless the Contractor submits a “disclosure of interested parties” (Form 1295) to NTTA at the time the Contractor submits the signed contract to NTTA for execution by NTTA.

If the Contract under this procurement is of a type that requires the Contractor to submit Form 1295, it will be the Contractor’s responsibility to submit the form as required by law. The Contractor may obtain information about the Contract from the Solicitation Contact Person identified on the cover page of this RFB. The Contractor must use the online application at the Texas Ethics Commission website to enter the required information on Form 1295 and print a copy of the completed form, which will include a certification of filing that will contain a unique certification number.

An authorized agent of the Contractor must sign the printed copy of the form and have the form notarized. The completed Form 1295 with the certification of filing must be delivered to NTTA’s Procurement Department, when the contract signed by the Contractor is delivered to NTTA for execution. NTTA will not execute the contract, and no contract will be formed if NTTA has not received the completed Form 1295 with the certification of filing.

NTTA must notify the Texas Ethics Commission of the receipt of the filed Form 1295 with the certification of filing not later than the 30th day after the date the contract binds all parties to the contract. The commission will post the completed Form 1295 to its website within seven business days after receiving notice from NTTA.

Please refer to the information at the Texas Ethics Commission’s website for instructions on registering and completing Form 1295.

Hold Harmless Agreement Each Bidder agrees to protect, defend, indemnify, and hold harmless NTTA and its directors, officers, agents, and employees from any and all costs, claims, and damages of every kind and nature (including attorneys’ fees) made, rendered, or incurred by or on behalf of every person or corporation whatsoever, including the parties hereto and their employees that may arise, occur, or grow out of any acts, actions, work, or other activity done by the Bidder, its employees, subcontractors, or any independent contractor working under the direction of either the Bidder or subcontractor in connection with the preparation and submission of a Bid.

Equal Opportunity NTTA is an equal-opportunity employer. Each Bidder submitting a Bid agrees not to refuse to hire, discharge, promote, demote, or otherwise discriminate in matters of

13 Rev. January 2026 compensation against any person otherwise qualified solely because of race, creed, sex, sexual orientation, gender identity, veteran status, national origin, ancestry, or physical handicap.

Disclaimer of Liability NTTA will NOT hold harmless or indemnify any Bidder for any liability whatsoever.

Licenses/Certificates NTTA reserves the right to require documentation that each Bidder is an established business and is abiding by all laws applicable to the Bidder and of the State of Texas.

If Bidder is required by any regulatory agency to maintain professional license or certification to provide any product and/or service solicited under this RFB, NTTA reserves the right to require Bidder to provide documentation of its current license and/or certification before considering its Bid and/or before awarding a Contract.

Notice of Impropriety If a Bidder has knowledge of conduct by an NTTA employee in connection with this procurement that the Bidder reasonably believes may be unethical or a violation of law or may create an appearance of impropriety by such person in his or her capacity as an NTTA employee, the Bidder agrees promptly to report such conduct to NTTA’s General Counsel, who is NTTA’s official Ethics Officer.

Force Majeure NTTA will not be liable for defaults or delays due to acts of God or the public enemy, acts or demands of any governmental agency, strikes, fires, floods, accidents, or other unforeseeable causes beyond its control and not due to its fault or negligence.

Procurement Protests NTTA encourages Bidders promptly to bring questions and concerns relating to this RFB to NTTA’s attention pursuant to the process set forth in the “Instructions to Bidders”. Any formal protest relating to this RFB or the Contract award hereunder must be made in writing and submitted to the Director of Procurement Services no later than five (5) business days after the earlier of the (i) date the protestor was or reasonably should have been aware of the matter giving rise to the protest or (ii) the date the Contract award was made by the NTTA Board of Directors. A “business day” under this RFB is any day NTTA’s administrative offices (as distinguished from its Customer Service Center) are open for the regular conduct of NTTA business.

Each protest must comply and will be treated in accordance with NTTA’s Procurement Policy, which may be found on NTTA’s website, ntta.org (currently under “Policies” in the “Who We Are” section) and is incorporated into this RFB by reference.

Bidders understand and agree that in light of NTTA’s operational needs and customer service obligations, the filing of a protest or any legal action challenging any aspect of this RFB or the Contract award thereunder will not prevent NTTA from proceeding with the RFB process, a Contract award thereunder, or utilization of the services

14 Rev. January 2026 requested through this RFB. To the fullest extent allowed by law, Bidders waive any claim for injunctive relief pertaining to this RFB, the contract award, or the commencement of services hereunder. By submitting a response to this RFB, Bidders unconditionally and irrevocably acknowledge that adequate remedies exist at law, without resort to injunctive or other equitable relief, to fully redress any potential claim arising in connection with this RFB.
