Bid Number: IFB #66-190015RL Vendor: ______If Vendors have questions, issues, or exceptions regarding any term, condition, instruction or other component within this IFB, those shall be submitted as questions in accordance with in the instructions in Section 2.3 BID QUESTIONS. If the University determines that any changes will be made as a result of the questions asked, then such decisions will be communicated in the form of an IFB addendum. The University may also elect to leave open the possibility for later negotiation and amendment of specific provisions of the Contract that have been addressed during the question and answer period. Other than through this process, the University rejects and will not be required to evaluate or consider any additional or modified terms and conditions or Instructions to Vendor submitted with Vendor’s bid document. This applies to any language appearing in or attached to the document as part of the Vendor’s bid that purports to vary any terms and conditions or Vendors’ instructions herein or to render the bid non-binding or subject to further negotiation. Vendor’s bid shall constitute a firm offer. By execution and delivery of a bid in response to this Invitation for Bids, Vendor agrees that any additional or modified terms and conditions, including Instructions to Vendors, whether submitted purposely or inadvertently, or any purported condition to the offer shall have no force or effect, and will be disregarded. Noncompliance with, or any attempt to alter or delete, this paragraph shall constitute sufficient grounds to reject Vendor’s bid as nonresponsive.
If a Vendor desires modification of the terms and conditions of this solicitation, it is urged and cautioned to inquire during the question period, in accordance with the instructions in the Bid Questions Section, about whether specific language proposed as a modification is acceptable to or will be considered by the University. Identification of objections or exceptions to the State’s terms and conditions in the bid itself shall not be allowed and shall be disregarded or the bid rejected. By executing and submitting its bid in response to this IFB, Vendor understands and agrees that the University may exercise its discretion not to consider any and all proposed modifications a Vendor may request and may accept Vendor’s bid under the terms and conditions in this IFB.
3.0 METHOD OF AWARD AND BID EVALUATION PROCESS
3.1 METHOD OF AWARD All qualified bids will be evaluated and award or awards will be made to the lowest responsive and responsible bid meeting specifications.
While the intent of this IFB is to award a Contract to single vendor for the entire roof project, the University reserves the right to make separate awards to different Vendors for one or more portions of the work, to not award one or more portions, or to cancel this IFB in its entirety without awarding a Contract, if it is considered to be most advantageous to the University to do so.
The University reserves the right to waive any minor informality or technicality in bids received.
3.2 CONFIDENTIALITY AND PROHIBITED COMMUNICATIONS DURING EVALUATION During the evaluation period—from the date bids are opened through the date the contract is awarded—each Vendor submitting a bid (including its representatives, sub-contractors and/or suppliers) is prohibited from having any communications with any person inside or outside the University, other government agency office, or body (including the purchaser named above, department secretary, agency head, members of the general assembly and/or governor’s office), or private entity, if the communication refers to the content of Vendor’s bid or qualifications, the contents of another Vendor’s bid, another Vendor’s qualifications or ability to perform the contract, and/or the transmittal of any other communication of information that could be reasonably considered to have the effect of directly or indirectly influencing the evaluation of bids and/or the award of the contract. A Vendor not in compliance with this provision shall be disqualified from contract award, unless it is determined in the University’s discretion that the communication was harmless, that it was made without intent to influence and that the best interest of the University would not be served by the disqualification. A Vendor’s bid may be disqualified if its sub-contractor and supplier engage in any of the foregoing communications during the time that the procurement is active (i.e., the issuance date of the procurement to the date of contract award). Only those discussions, communications or transmittals of information authorized or initiated by the
Rev. 06/2018 Page 6 of 21
Bid Number: IFB #66-190015RL Vendor: ______University for this IFB or general inquiries directed to the purchaser regarding requirements of the IFB (prior to bid submission) or the status of the contract award (after submission) are excepted from this provision.
3.3 BID EVALUATION PROCESS The University shall review all Vendor responses to this IFB to confirm that they meet the specifications and requirements of the IFB. a) Bids are requested for the project as specified, or approved equivalent in design, function and performance. The University reserves the right to reject any bid on the basis of fit, form and function as well as cost. All information furnished on this bid may be used as a factor in determining the award of this contract. b) Bids will be received from each responsive Vendor in a sealed envelope or package.
c) All bids shall be received by the University not later than the date and time specified on the cover sheet of this IFB.
d) At that date and time specified as the bid opening, the package containing the bids from each responding firm will be opened publicly and the name of the Vendor and the price(s) bid announced.
e) The University shall review all Vendor responses to this IFB to confirm that they meet the specifications and requirements of the IFB.
f) For all responses that pass the initial review process, the University will review and assess the Vendors’ pricing. The University may request additional formal responses or submissions from any or all Vendors for the purpose of clarification or to amplify the materials presented in any part of the bid. Vendors are cautioned, however, that the University is not required to request clarification, and often does not. Therefore, all bids should be complete and reflect the most favorable terms available from the Vendor. Prices bid cannot be altered or modified as part of a clarification.
g) Bids will be evaluated, based on the award criteria identified in Section 3.1 METHOD OF AWARD.
Vendors are cautioned that this is a request for offers, not an offer or request to contract, and the University reserves the unqualified right to reject any and all offers at any time if such rejection is deemed to be in the best interest of the University.
The University reserves the right to reject all original offers and request one or more of the Vendors submitting bids within a competitive range to submit a best and final offer (BAFO), based on discussions and negotiations with the University, if the initial responses to the IFB have been evaluated and determined to be unsatisfactory.
Upon completion of the evaluation process, the University will make award(s) based on the evaluation and post the award(s) to IPS under the IFB number for this solicitation. Award of a Contract to one Vendor does not mean that the other bids lacked merit, but that, all factors considered, the selected bid was deemed most advantageous and represented the best value to the University.
3.4 PERFORMANCE OUTSIDE THE UNITED STATES Vendor shall complete ATTACHMENT B: LOCATION OF WORKERS UTILIZED BY VENDOR. In addition to any other evaluation criteria identified in this IFB, the University may, for purposes of evaluating proposed or actual contract performance outside of the United States, also consider how that performance may affect the following factors to ensure that any award will be in the best interest of the University:
• Total cost to the University • Level of quality provided by the Vendor • Process and performance capability across multiple jurisdictions • Protection of the University’s information and intellectual property • Availability of pertinent skills • Ability to understand the University’s business requirements and internal operational culture
Rev. 06/2018 Page 7 of 21
Bid Number: IFB #66-190015RL Vendor: ______• Particular risk factors such as the security of the University’s information technology • Relations with citizens and employees • Contract enforcement jurisdictional issues
3.5 INTERPRETATION OF TERMS AND PHRASES This Invitation for Bids serves two functions: (1) to advise potential Vendors of the parameters of the solution being sought by the Department; and (2) to provide (together with other specified documents) the terms of the Contract resulting from this procurement. As such, all terms in the Invitation for Bids shall be enforceable as contract terms in accordance with the General Contract Terms and Conditions. The use of phrases such as “shall,” “must,” and “requirements” are intended to create enforceable contract conditions. In determining whether bids should be evaluated or rejected, the Department will take into consideration the degree to which Vendors have proposed or failed to propose solutions that will satisfy the Department’s needs as described in the Invitation for Bids. Except as specifically stated in the Invitation for Bids, no one requirement shall automatically disqualify a Vendor from consideration. However, failure to comply with any single requirement may result in the Department exercising its discretion to reject a bid in its entirety.
4.0 REQUIREMENTS This Section lists the requirements related to this IFB. By submitting a bid, the Vendor agrees to meet all stated requirements in this Section as well as any other specifications, requirements and terms and conditions stated in this IFB. If a Vendor is unclear about a requirement or specification or believes a change to a requirement would allow for the University to receive a better bid, the Vendor is urged and cautioned to submit these items in the form of a question during the question and answer period in accordance with the Bid Questions Section.
4.1 PRICING Bid price shall constitute the total cost to the University for completed project including all applicable charges for shipping, delivery, handling, administrative and other similar fees. Vendor shall not invoice for any amounts not specifically allowed for in this IFB. Complete ATTACHMENT A: PRICING FORM and include with Bid.
4.2 DELIVERY AND INSTALLATION Delivery shall not be considered to have occurred until installation has been completed. Upon completion of the installation, the Vendor shall remove and properly dispose of all waste and debris from the installation site. The Vendor shall be responsible for leaving the installation area clean and ready to use.
4.3 PRODUCT RECALL Vendor expressly assumes full responsibility for prompt notification to the Buyer listed on the face of this IFB of any product recall in accordance with the applicable state or federal regulations. The Vendor shall support the University, as necessary, to promptly replace any such products, at no cost to the University.
4.4 WARRANTY
Vendor warrants that all equipment/materials furnished under this IFB will be new, of good material and workmanship. The manufacturer warranty will be for a twenty (20) year period, per industry standard, from date the completed roof is put into operation. In addition, a 2 year Contractor Warranty shall cover the cost of all defective parts replacement, labor, freight, and technicians travel at no additional cost to the University.
The report of a problem does not presuppose that every call must result in an “on-site” visit for service/repair. The Vendor and/or service sub-contractor shall utilize best efforts to resolve problems in a timely fashion through the use of acceptable servicing methods to include, but not limited to, verbal problem analysis and remote diagnosis. The warranty requirement does not impose any additional duty on the University to make other than normal and good faith problem resolution efforts or expenditures of time.

ACCEPTANCE AND REJECTION: The University reserves the right to reject any and all bids, to waive any informality in bids and, unless otherwise specified by the Vendor, to accept any item in the bid. If either a unit price or an extended price is obviously in error and the other is obviously correct, the incorrect price will be disregarded.
4. BASIS FOR REJECTION: Pursuant to 01 NCAC 05B .0501, the University reserves the right to reject any and all offers, in whole or in part, by deeming the offer unsatisfactory as to quality or quantity, delivery, price or service offered, non-compliance with the requirements or intent of this solicitation, lack of competitiveness, error(s) in specifications or indications that revision would be advantageous to the University, cancellation or other changes in the intended project or any other determination that the proposed requirement is no longer needed, limitation or lack of available funds, circumstances that prevent determination of the best offer, or any other determination that rejection would be in the best interest of the University.
5. EXECUTION: Failure to sign the Execution page (page 3 of the IFB) in the indicated space will render bid non- responsive, and it shall be rejected.
6. ORDER OF PRECEDENCE: In cases of conflict between specific provisions in this solicitation or in any resulting contract, the order of precedence shall be (high to low) (1) any special terms and conditions specific to this IFB, including any negotiated terms; (2) requirements and specifications in Sections 2, 4, and 5 of this IFB; (3) North Carolina General Contract Terms and Conditions in ATTACHMENT D: NORTH CAROLINA GENERAL CONTRACT TERMS AND CONDITIONS; (4) Instructions in ATTACHMENT C: INSTRUCTIONS TO VENDORS; and (5) Vendor’s Bid.
7. INFORMATION AND DESCRIPTIVE LITERATURE: Vendor shall furnish all information requested and in the spaces provided in this document. Further, if required elsewhere in this bid, each Vendor shall submit with their bid sketches, descriptive literature and/or complete specifications covering the products offered. Reference to literature submitted with a previous bid or available elsewhere will not satisfy this provision. Bids that do not comply with these requirements shall constitute sufficient grounds to reject the bid.
8. RECYCLING AND SOURCE REDUCTION: It is the policy of the University to encourage and promote the purchase of products with recycled content to the extent economically practicable, and to purchase items which are reusable, refillable, repairable, more durable and less toxic to the extent that the purchase or use is practicable and cost- effective. We also encourage and promote using minimal packaging and the use of recycled/recyclable products in the packaging of commodities purchased. However, no sacrifice in quality of packaging will be acceptable. The company remains responsible for providing packaging that will adequately protect the commodity and contain it for its intended use. Companies are strongly urged to bring to the attention of purchasers those products or packaging they offer which have recycled content and that are recyclable.
9. CERTIFICATE TO TRANSACT BUSINESS IN NORTH CAROLINA: As a condition of contract award, each out-of- State Vendor that is a corporation, limited-liability company or limited-liability partnership shall have received, and shall maintain throughout the term of The Contract, a Certificate of Authority to Transact Business in North Carolina from the North Carolina Secretary of State, as required by North Carolina law. A University contract requiring only an isolated transaction completed within a period of six months, and not in the course of a number of repeated transactions of like nature, shall not be considered as transacting business in North Carolina and shall not require a Certificate of Authority to Transact Business.

Bid Number: IFB #66-190015RL Vendor: ______10. SUSTAINABILITY: To support the sustainability efforts of the State of North Carolina we solicit your cooperation in this effort. Pursuant to Executive Order 156 (1999), it is desirable that all responses meet the following: • All copies of the bid are printed double sided. • All submittals and copies are printed on recycled paper with a minimum post-consumer content of 30%. • Unless absolutely necessary, all bids and copies should minimize or eliminate use of non-recyclable or non- reusable materials such as plastic report covers, plastic dividers, vinyl sleeves, and GBC binding. Three-ringed binders, glued materials, paper clips, and staples are acceptable. • Materials should be submitted in a format which allows for easy removal, filing and/or recycling of paper and binder materials. Use of oversized paper is strongly discouraged unless necessary for clarity or legibility.
11. HISTORICALLY UNDERUTILIZED BUSINESSES: Pursuant to General Statute 143-48 and Executive Order #150 (1999), the University invites and encourages participation in this procurement process by businesses owned by minorities, women, disabled, disabled business enterprises and non-profit work centers for the blind and severely disabled.
12. RECIPROCAL PREFERENCE: G.S. 143-59 establishes a reciprocal preference requirement to discourage other states from favoring their own resident Vendors by applying a percentage increase to the price of any bid from a North Carolina resident Vendor. The “Principal Place of Business” is defined as that principal place from which the trade or business of the Vendor is directed or managed.
13. INELIGIBLE VENDORS: As provided in G.S. 147-86.59 and G.S. 147-86.82, the following companies are ineligible to contract with the State of North Carolina or any political subdivision of the State: a) any company identified as engaging in investment activities in Iran, as determined by appearing on the Final Divestment List created by the State Treasurer pursuant to G.S. 147-86.58, and b) any company identified as engaged in a boycott of Israel as determined by appearing on the List of restricted companies created by the State Treasurer pursuant to G.S. 147- 86.81. A contract with the State or any of its political subdivisions by any company identified in a) or b) above shall be void ab initio.
14. CONFIDENTIAL INFORMATION: To the extent permitted by applicable statutes and rules, the University will maintain confidential trade secrets that the Vendor does not wish disclosed. As a condition to confidential treatment, each page containing trade secret information shall be identified in boldface at the top and bottom as “CONFIDENTIAL” by the Vendor, with specific trade secret information enclosed in boxes or similar indication. Cost information shall not be deemed confidential under any circumstances. Regardless of what a Vendor may label as a trade secret, the determination whether it is or is not entitled to protection will be determined in accordance with G.S. 132-1.2. Any material labeled as confidential constitutes a representation by the Vendor that it has made a reasonable effort in good faith to determine that such material is, in fact, a trade secret under G.S. 132-1.2. Vendors are urged and cautioned to limit the marking of information as a trade secret or as confidential so far as is possible.
15. PROTEST PROCEDURES: When a Vendor wishes to protest a Contract resulting from this solicitation that is awarded by the University, a Vendor shall submit a written request addressed to the University Purchasing Officer at 9201 University City Blvd, Reese Building 3rd Floor, Charlotte, NC, 28223.
