INFORMATION FOR BIDDERS

ELECTRONIC SUBMITTAL PROCESS

To be considered, Bids (Section IV – Proposal) shall be received by the bid closing date and time to the following email address dpwbid@baltimorecountymd.gov. The contract number and company name should be referenced in the Subject Line of the email. Bids may not be submitted by any other means. Bids that are mailed or otherwise delivered to the Purchasing Division (including emails which indicate links to locations where the bid may be downloaded) and/or emails sent to any other Baltimore County email address will not be accepted.

Late Bids will not be considered. Bidders are strongly encouraged not to wait until the last minute to submit bids. The time stated on the auto-receipt (described below) will be definitive of the time of receipt. Bids received after the deadline will not be accepted. Bidders are advised that the County cannot receive email attachments greater in size than twenty-five (25) megabytes and this size limitation may be further reduced by requirements of the Bidder’s email provider which are beyond the control of the County. Bidder should consider separating any large bid attachment into multiple parts and emailing each part separately. In such case, Bidder will note that each email is 1 of 2, 2 of 2, etc.

Multiple part bids will not be considered unless all parts are received by the bid closing date and time.

After submitting a Bid to dpwbid@baltimorecountymd.gov, and upon successful receipt by the County thereof, Bidder will receive an auto-receipt email. This receipt is proof that the bid has been received by the Division of Construction Contracts Administration and should be retained for Bidder’s records. In the case of a bid submitted in multiple parts as described above, an auto-receipt email will be generated for each part. The County has no obligation to consider any Bid for which an auto-receipt was not generated.

As with any system, power outages or technology problems may arise that are outside of the County’s control and could affect your submission. The County will not be held accountable for such issues that may delay the transmission of any Bid.

NOTE: Electronic copy of the Bid Bond will be accepted at bid opening. The apparent low bidder is required to submit the original Bid Bond within ten (10) days after the bid opening to the Division of Construction Contracts Administration, 111 West Chesapeake Avenue, Room 300B, Towson, Maryland 21204.

INSTRUCTIONS AND SPECIFICATIONS

Refer to the enclosed proposal sheets for quantities to be bid upon. All proposals submitted on the attached form must give the price in clear figures for each item of the proposed work and be signed by the bidder with his name and address. Bidders must not change any item in the proposal for which a price has been stipulated by the County. Any change will cause rejection of the proposal.

NOTE: STATEMENT UNDER OATH FORM TO ACCOMPANY BID as per Baltimore County Purchasing Act 65-98, Section 15-94 and 15-95 which requires that the enclosed affidavit (see Proposal Affidavit pages in Section IV) be completed and submitted as part of the sealed bid.

Proposals made on any other than the attached form will not be considered. All papers included in, bound thereto, or attached to the Proposal Form are necessary parts thereof and shall not be detached, separated, or altered in their intent.

Changes in the phraseology of the proposal, additions, or limiting provisions will render the proposal informal or void and may cause its rejection.

All right is hereby reserved by the Purchasing Agent to reject any or all proposals and to waive formalities and technicalities as the interest of the County may require.

No successful bidder may withdraw his bid within One Hundred and Twenty (120) days after the opening thereof.

The successful bidder will be required to be bonded to Baltimore County, Maryland to the sum of One Hundred per Cent (100%) of the amount of his proposal or proposals according to the form of bond hereto attached for projects in excess of $25,000.00.

This Proposal must be accompanied by a Bid Bond in an amount of 5% of the bid, the exact amount to be determined by the difference between the low bid and the next lowest bid if two or more bids are received, or 5% of the bid if one bid is received. This guarantees payment of the amount thus determined in case of a default in any matter specified as required before award or in any matter resulting in failure to execute and deliver an Agreement, together with Payment and Performance Bonds, after award. The Bid Bond must be in the form accompanying the Proposal executed by a Surety licensed in the State of Maryland. The Surety must be currently rated “B” or better by the A. M.

Best Company, and the bid must be in an amount less than, or equal to, the underwriting limitation contained in Department of Treasury Circular 570 as amended at the time of the underwriting.

All work to be performed under this contract shall be done under strict compliance with Baltimore County Department of Public Works and Transportation September 2023 Standard Specifications for Construction and Materials and Standard Details for Construction and any and all proposed revisions thereto as of the date of advertisement and copies of which are available on the County’s website at www.baltimorecountymd.gov/departments/public-works/standards, and all of which are made a part hereof and incorporated herein (collectively, the “Specifications”).

If the bidder to whom an award is made shall fail to execute the contract and bond hereto attached and as herein provided, the award may be annulled and the contract awarded to the lowest responsible bidder who has consented to a time extension, and such bidder shall fulfill every stipulation embraced herein as if he were the original party to whom the award was made, or the Purchasing Agent may reject all of the bids as the interest of the County may require.

The Bid Bond of the three lowest bidders is deemed to be effective until the execution and delivery of the Contract Agreement, together with Payment and Performance Bonds for projects in excess of $25,000.00 or until rejection of all bids, whereupon Surety is deemed relieved of all further obligations under the bid bonds provided.

Bidders must examine the drawings and specifications carefully and must make a personal examination of the location and nature of the proposed work. In case doubt shall arise as to the meaning or intent of anything shown on the drawings or comprised in the specification, inquiry shall be made of the Director of Public Works and Transportation at least five (5) days prior to the date of http://www.baltimorecountymd.gov/departments/public-works/standards bid opening. The submission of the Proposal shall indicate that the bidder thoroughly understands the drawings and the terms of the Specifications.

To better ensure fair competition and to permit a determination of the lowest bidder, unresponsive bids or bids obviously unbalanced may be rejected by the Purchasing Agent.

Bidders are required to fill out the total price column and total their proposals so that the result of the bidding, barring possible arithmetical errors, will be known at once. Any errors in computations will be corrected by the Engineer when the proposals are canvassed. Where the unit price and the total price are at variance, the unit price will prevail.

Bidders must be prepared to complete the work within the time stated in the proposal.

NOTE: ONLY CONTRACTORS FORMALLY PRE-QUALIFIED WITHIN THE

ADVERTISED WORK CLASSIFICATION BY THE DIRECTOR OF PUBLIC WORKS AND

TRANSPORTATON OF BALTIMORE COUNTY 10 CALENDAR DAYS PRIOR TO BID

OPENING WILL BE ELIGIBLE TO SUBMIT BIDS.

Contracts for work under this proposal will obligate the contractors and subcontractors not to discriminate in employment practices. Bidders must, if requested, submit a compliance report concerning their employment practices and policies in order to maintain their eligibility to receive the award of the contract. Successful bidders must be prepared to comply in all respects with the Contract Provisions regarding nondiscrimination.

Baltimore County has adopted a Minority Business Enterprise (MBE) program and Women’s Business Enterprise (WBE) Program. The percentage of participation applies to the contract amount awarded to the Contractor. Qualified minority subcontractors are those certified as being a Minority Business Enterprise by the following:

1. Maryland Department of Transportation Certification Committee (MDOT)

2. City of Baltimore, Minority Business Certification Council

Projects funded by the Federal Highway Administration are limited to the certification listed under #1

(MDOT).

More detailed information regarding the County’s MBE/WBE Program can be obtained from the County MBE Office, telephone (410) 887-3407. See Executive Order dated December 6, 2022.

MBE/WBE Participation Summary and Forms A, B, C, D and E enclosed in this proposal booklet.

NOTE: If you do not complete and submit the enclosed forms with your bid or offer to the County, the County may, in its sole discretion, deem your bid or offer NON-RESPONSIVE and accordingly the COUNTY WILL NOT CONSIDER YOU FOR CONTRACT AWARD.

The County reserves the right to require the low bidder to produce evidence indicating that the company’s financial condition is equal to, or better than, that enjoyed by the company at the time of prequalification. This additional information may be in the form of a financial statement or other evidence satisfactory to the Office of Budget and Finance.

Bidders’ attention is directed to the requirement that a permit must be obtained from the Baltimore County Bureau of Highways and Bureau of Traffic Engineering prior to cutting any County road for the purpose of obtaining sub-surface soils information, and permission must be obtained from the State Highways Administration prior to making any openings in a State road.

Under no circumstances shall a bidder enter upon any property outside a County or State road for the purpose of securing sub-surface soils information until permission is received from the property owner. The fact that the County has obtained a utility easement does not give the bidder the right to enter upon the property.

Prevailing index price of asphalt cement/ton $807.50.

INCLEMENT WEATHER POLICY: If Baltimore County General Government Offices are open or open with liberal leave the day the bids are due, the bids are due as stated in the bid documents (date and time).

ONLY when the Baltimore County General Government Offices are OFFICIALLY CLOSED the day the bids are due, the bid date will be postponed and an Addendum will be issued the next business (or next day buildings are officially open) day the county offices are open with the new bid date and time.

BID TABULATIONS: All bid tabulations will be confidential until after final award, at which time the total bid amounts for all bidders, as well as the complete bid tabulations for the top three (3) bidders, can be inspected by others when requested in writing pursuant to the Maryland Public Information Act.

ALTERNATIVE SOURCES OF CONTRACT BONDS: In the event your company is unable to qualify for bonding through a traditional commercial surety company, you may qualify for the required bonds through the State of Maryland, Department of Commerce (DOC). The Maryland Small Business Development Financing Authority (MSBDFA, pronounced Mis-Bid-Fa), an agency of DOC, operates a Surety Bond Program designed to assist small businesses, based in Maryland, that are unable to obtain adequate bonding on reasonable terms in the commercial marketplace. MSBDFA provides bid, payment and performance bonds for contracts funded by government agencies, regulated utilities and private entities. The penal sums of the bonds are limited to the aggregate amount of $2,500,000 and companies may pre-qualify for multiple bonds within pre-approved terms and conditions. MSBDFA also provides lines of credit, term loans and loan guarantees to help qualified businesses purchase equipment and real property, make improvements to leased property, refinance existing debt and assist them with their working capital needs.

In case of any conflict with the Baltimore County “Standard Specifications for Construction and Materials,” dated September 2023, “Standard Details for Construction,” dated September 2023, all associated Errata, Addenda, and Supplemental Details or other sections of the Contract, these Special Conditions shall govern.

2. CONTRACT DOCUMENTS – DESIGN INTENT

Contract Drawings to be followed for this Contract shall be those approved drawings on file at the office of the Engineer. The Contract Drawings contain information as to amount, location, dimension and detail of the work to be performed in accordance with the Specifications. No deviation shall be permitted from the Contract Drawings and Specifications unless authorized in writing by the Engineer. Deviation by the Contractor from the Contract Documents without the Engineer’s prior written approval shall be at the Contractor’s risk and expense, including the expense of removal and restoration if so ordered.

Any discrepancies found between the Drawings and Specifications or any inconsistencies in the Drawings or Specifications shall be immediately reported to the Engineer, in writing, who shall promptly correct such inconsistencies or ambiguities in writing. Work done by the Contractor after his/her discovery of such discrepancies, inconsistencies or ambiguities prior to corrections directed by the Engineer shall be done at the Contractor’s risk. In the case of discrepancy or omission, the Engineer will determine the intent of the design in issuing clarifying or corrective instructions.

In order to fulfill the requirements of the Contract, conformance is required with both the Contract Drawings and Specifications. The Contractor is not released from responsibility for performing work called for in the Contract Drawings but not in the Specifications or vice versa; mention of work in either part is sufficient to include it under the Contract. In all cases, the decision of the Engineer will be final.

GENERAL REQUIREMENTS Page 2 of 22

May 27, 2026

The work under this Contract shall be built of the materials, sizes, dimensions, on the lines and slopes, at the depths, with the connections, and in a manner called for by the Specifications and as shown on the Contract Drawings. All materials and equipment installed as part of the permanent installation shall be new.

3. EXISTING UTILITY FACILITIES

Existing utilities shown in the Contract Drawings are from available records and are shown for the Contractor’s convenience only. The County expressly disclaims any responsibility for accuracy or completeness of information shown. Existing utilities and services shall be carefully investigated and protected by the Contractor. The Contractor shall test pit existing underground utilities with caution to verify information to his/her satisfaction prior to beginning work. The Contractor is responsible for locating, protecting and maintaining uninterrupted service on all existing utilities. Any damage to utilities caused by the Contractor’s work shall be immediately repaired by the Contractor to the satisfaction of the Engineer, using materials of the kinds damaged. The Contractor shall be liable for any damages to existing utilities caused by his/her operations as stipulated in Section GP-5.05.

4. SUBMITTALS

Within 10 days after notice to proceed, the Contractor shall submit a submittal schedule listing as near as practicable by specification section number, all submittals required and approximate date submittal will be forwarded. No submittals will be reviewed by the Engineer until the submittal schedule has been submitted and approved.

Submittals are generally defined as all drawings, diagrams, illustrations, catalog cut sheets, product data sheets, brochures, schedules, bills of material, and other data, certified correct for construction, which are prepared by the Contractor, his/her subcontractors, suppliers or distributors, or equipment fabricators or manufacturers, and which illustrate the manufacture, fabrication, construction, installation of the work, or a portion thereof.

The Contractor's attention is specifically directed to the fact that shop drawing submittal drawings are required in advance, and shall be submitted for each and every element of the work including, but not limited to: grinder equipment, air and vacuum release valves, gate valves, vaults, pipe material, pipe layout, pipe coatings, pipe fittings, pipe closures, pipe supports, all piping regardless of size or whether fabricated on or off the project site, pipe restraints, tapping sleeve, and all other shop drawings which may be necessary, in the opinion of the Engineer, to comply with the all-inclusive intent of this requirement. Each submittal shall be assigned a sequential number; Submittal No. 1, 2, 3, 4, etc. for purposes of easy identification, and shall retain its assigned number, with appropriate subscript, on all required resubmissions. Changing manufacturers or models during the course of the submittal process shall not be cause for assigning a new submittal number. Once an item of work has been assigned a submittal number, that item of work shall retain the same number, for the duration of the project. The following stamp shall be affixed to each submittal and appropriately completed.

GENERAL REQUIREMENTS Page 3 of 22

May 27, 2026

Resubmittals shall be labeled with the letter "R" followed by the number of the resubmission. Example: The Contractor's tenth submittal, being resubmitted for the first time shall be numbered Submittal No. 10R1, resubmitted for the second time shall be numbered Submittal No. 10R2, etc.

All shop drawings shall be in conformity with the Contract Drawings and Special Provisions. All shop drawings except diagrams, illustrations, brochures, and schedules shall be to appropriate scale, but in no case smaller than 1/4-inch equals 1 foot, and shall give all dimensions required for manufacture, fabrication, assembly, installation, and incorporation in the work. All shop drawings shall be complete, accurate, and distinct, and shall show outline and section views, details, kinds of materials to be used, the kind of machine work and finish to be applied, and the installed locations of the said materials, equipment, accessories, appurtenances, and related items.

Where applicable, shop drawings shall be 24 inches by 36 inches in size with a 1 1/2-inch binding margin on left hand side of sheet. The Contractor may incorporate one (1) or more small drawings on prints 24 inches by 36 inches in size. Diagrams, illustrations, brochures, schedules, and other data may be prepared and executed, complete, on sheets measuring 8 1/2 inches by 11 inches. Shop drawings submitted other than as specified herein will be returned for resubmittal without being reviewed.

After checking and verifying all field measurements, the Contractor shall submit to the Engineer, for approval, a digital copy of all submittals, which shall have been checked by and stamped with the approval of the Contractor and identified as shown herein. The information shown on the submittals shall be complete with respect to dimensions, design criteria, materials of construction, and other requirements as specified or shown in the Contract Documents to enable the Engineer to review the information as required.

Machinery outline drawings alone are not acceptable. At the time of each submission, the Contractor shall call to the Engineer's attention, in writing, any deviations that the submittals may have from the requirements of the Contract Documents.

GENERAL REQUIREMENTS Page 4 of 22

May 27, 2026

The Engineer will check submittals with reasonable promptness, but his/her checking and approval shall be only for conformance with the design concept of the project and for compliance with the information given in the Contract Documents. The approval of a separate item as such shall not indicate approval of the assembly in which the item functions. The Contractor shall make any corrections required by the Engineer and shall resubmit the required number of corrected copies of each submittal until approved. The Contractor shall direct specific attention to revisions called for by the Engineer on previous submissions.

The Engineer's approval of submittals shall not relieve the Contractor from his/her responsibility for any deviations from the requirements of the Contract Documents unless the Contractor has in writing called the Engineer's attention to such deviations at the time of submission and the Engineer has given written approval to the specific deviation, nor shall any approval by the Engineer relieve the Contractor from responsibility for errors or omissions in the submittals. Submittals shall be submitted with sufficient time provided for checking, return to the Contractor, and/or resubmission as required. The words "APPROVED" or "APPROVED AS NOTED" or words of similar import placed by the Engineer on a submittal means that all items and details of the submittal are fully approved with the exception of those items or details that are specifically marked for further action.

When the submission is marked "RESUBMIT" it means that the material or product can probably fulfill the intent of the Contract Documents but that enough questions or comments have arisen to require a corrected or updated submission. If the material submitted represents a product that is totally unsatisfactory and probably will not under any circumstances meet Contract requirements, it will be marked "REJECTED" and will not be reconsidered by the Engineer. The withholding of an approval by the Engineer of any submittal in its entirety, including required certifications, shall under no circumstances constitute a basis for delay in arranging for and proceeding with the manufacturing, fabricating, delivering, and installing, in accordance with the Contract, of those items or details in such submittals which may have been approved.

The Contractor's attention is specifically directed to the fact that no work shall be fabricated, nor materials ordered, nor any construction performed, prior to approval by the Engineer of submittals applicable thereto.

Construction performed in violation of this requirement will be neither approved nor certified for payment until applicable submittals have been approved. If the Engineer so directs, the Contractor shall disassemble, raze, and remove any such construction performed prior to approval by the Engineer of submittals applicable thereto, and the Contractor will be allowed neither additional compensation nor extension of Contract time thereto.

If the Contractor orders or causes to be ordered or delivered any material in violations of this requirement, he/she does so at his/her own risk, and such equipment, machinery or materials shall neither be installed in the work nor stored on the site of the work. If, after submission and review of applicable submittals, the Engineer determines that any such

GENERAL REQUIREMENTS Page 5 of 22

May 27, 2026 materials do not meet the requirements of the Contract Documents, such materials will be rejected, and the Contractor shall be allowed neither additional compensation nor extension of time therefore.

The Contractor's attention is specifically and especially directed to the fact that because manufacturer's standards and procedures are subject to unilateral changes over which the County has no control, the stipulations herein are applicable, and will be enforced, even for those elements of materials which may be specified by manufacturer and model or catalog number in these Contract Documents.

5. CONTRACT AS-BUILT DRAWINGS

A. Contract and As-Built Drawings. The Contractor shall have Contract Drawings showing the location, dimensions and sizes of the materials, on the lines and slopes, at the depths, with the connections and the manner in which they are to be placed as called for by the Specifications. The Contractor shall also maintain a complete set of these Contract Drawings showing As-Built construction changes for use in maintaining a permanent record of the completed construction that shall become the property of Baltimore County at the completion of the Contract.

Survey data shall consist of horizontal positions based upon the Contract Drawing datum, or as directed by the Department of Public Works and Transportation, and shall be accurate to 0.1 feet. Vertical datum shall be based upon the Contract drawing datum, or as directed by the Department of Public Works and Transportation, and shall be accurate to 0.1 feet. As-Built positions and elevations shall be certified and sealed by a Maryland Licensed Property Line Surveyor or Professional Land Surveyor.

At the Contractor’s option, the required “As-Built” survey data, as described above, may be provided on either individual sketches or on the “red-lined” As-Built drawings that he/she is to supply to the Engineer at the completion of the Contract.

Items to be verified and included on the As-Built drawings shall be based on As- Built checklists to be provided by Baltimore County.

Final payment shall not be made and/or Contract acceptance shall not be given until the Contractor provides an acceptable As-Built plan and survey.

B. Digital As-Built Submission.

Final As-Built drawings shall be submitted in a digital format approved by Baltimore County. The drawings shall consist of the original Contract Drawing in black with all As-Built changes clearly noted in red. In addition to the digital As- Built drawings, a digital text file indicating the horizontal and vertical positions and the descriptions of the items indicated in paragraphs A.(1) through A.(4) shall be provided. The digital text file shall be in a format approved by Baltimore County.

C. Ground Profiles.

The ground profiles shown on the drawings represent the finished grade elevations along the centerline of the trenches, unless otherwise noted in the Contract Documents. Existing grades along utility trenches also shall be shown, if changes are proposed to the existing ground. No additional payment is made on lump sum bids where the actual elevations of the ground or surface over the structure differ from those shown on the profiles for pipe trenches.

6. SUBSTITUTION OF EQUIPMENT OR MATERIALS

Whenever a material, article or process is specified or described by using the name of a proprietary product or the name of a particular vendor or manufacturer followed by the phrase “or equal,” the specific item mentioned shall be understood as establishing type, function, dimension, appearance and quality desired and is to be the basis upon which bids are prepared.

Equipment or materials, other than those specified, will be permitted provided that, in the opinion of the Engineer, such equipment is equal to or better than that specified. Any such decision of the Engineer with respect to approval or disapproval of any equipment or material proposed to be substituted as an “or equal” is final, and the Contractor shall have no claim of any sort by reason of such decision.

If the Contractor proposes to provide equipment or materials as “or equal” to those specified, it shall be his/her responsibility to furnish complete, specific, detailed information from the manufacturer or supplier of such equipment or material establishing conformance with the requirements of the Contract Specifications. This shall consist of an item-by-item comparison of the Contract Specification requirements with the equipment or material proposed to be furnished. In the event the Contract Specifications mention a model number or other designated manufacturer in lieu of the detailed description and manufacturer, an item-by-item comparison shall be furnished of the equipment specified under the Contract and that proposed to be substituted. The Contractor shall bear the burden of responsibility of demonstrating that the equipment or material to be substituted is equal to, or of higher quality than, that specified. Submission of incomplete, insufficient or irrelevant data as evidence of compliance with this provision shall be grounds for denial of the Contractor’s request.

All requests for approval of equipment and materials other than specified shall be submitted by the bidders to the Baltimore County Department of Public Works and Transportation, Contract Division, in writing no less than fourteen (14) calendar days prior to the opening of bids for approval. If approved by the Department of Public Works and Transportation, all bidders will be notified through an addendum to these Specifications no less than seven

(7) days prior to the opening of bids. Upon extension of the opening date of the bids, the deadline for approval of equal or substitute equipment shall not be extended but shall remain fixed relative to the original date of the bid opening. Requests for changes to equipment or material must be made by the prime bidders, and requests for such changes by manufacturers or suppliers will neither be considered nor approved.

After the opening of bids, any request by the Contractor to substitute equipment or materials for those specified herein will be presumed to be for the purpose of saving money.

If such a request is approved, the Contractor shall provide the County with a credit equal to the difference between the net cost to the Contractor of the article submitted and the lowest cost to the Contractor of the article specified. The Contractor shall submit these

GENERAL REQUIREMENTS Page 8 of 22

May 27, 2026 figures accompanying each substitute submittal; no request for substitution of equipment or materials will be considered without such figures.

The Engineer may, at his/her discretion, authorize use of substitute items or materials at greater, less or equal cost to those specified when required due to the Contractor’s inability to obtain specified equipment or materials in a timely manner where unreasonable delays to the progress of the work may result.

In the case of the two aforementioned paragraphs, the Contractor shall submit a written request for permission to use substitute equipment or materials, furnishing full information as to the costs of the items or materials specified and the substitute item or material. Such information shall be of sufficient detail to permit verification by the Engineer of the costs submitted. If approved by the Engineer, written authorization for credit to the County or payment to the Contractor will be made based on the cost difference between the specified item and the substitute item.

All decisions of the Engineer with regard to credits to the County, payments to the Contractor or equipment and materials to be substituted, shall be final.

7. CERTIFICATION OF MATERIALS AND INSTALLATIONS

A. The Contractor shall furnish certificates from each manufacturer or from approved testing laboratories that all material used in the work is in accordance with these and all reference specifications. Upon completion of the work, and before acceptance by the County, the Contractor shall furnish the County with a certificate from each of the manufacturers of the equipment and mechanisms used in the work that such equipment and mechanisms furnished by him/her has been erected and installed in a satisfactory manner and is ready for continuous service and operation.

B. A statement originating from the Contractor, or any of his/her subcontractors, suppliers, or any other agent which merely indicates that a particular product, or component of a product, meets the requirements of the standard specified in the Contract Documents shall not be considered a certificate. Any such submittal made in this manner will not be approved and the corresponding product, or component of the product, shall not be incorporated into the work.

8. GUARANTEE

The Contractor shall guarantee all materials and equipment furnished and work performed for a period of two (2) years from the date of the Division of Construction Contracts Administration (DCCA) acceptance letter for that work. The Contractor warrants and guarantees that the completed work is free from all defects due to faulty materials, equipment and workmanship and is in every way fit for the use intended, including but not necessarily limited to, the following:
