PROCEDURES GOVERNING CLASSIFICATION AND

RATING OF PROSPECTIVE BIDDERS



  1. INTRODUCTION

This procedure provides guidance to General Contractors requesting prequalification to bid on MBTA construction projects. This procedural package includes the Contractor Prequalification Statement that must be submitted and approved by the Authority prior to permission to bid on projects. Once approved, General Contractors apply annually for re-approval.


I. DEFINITIONS
A. "Contractor" or "Prospective Bidder
The words "Contractor” or “Prospective Bidder" as used in these procedures shall include individuals, co-partnerships, associations, corporations, joint venturers, or joint stock companies and their representatives, trustees, or receivers, appointed by any court of competent jurisdiction. All corporations must show proof of registration with the Massachusetts Office of the Secretary of State to do business in Massachusetts.
B. "Authority”
The word "Authority” as used in these procedures shall mean the Massachusetts Bay Transportation Authority.
C. "Experience"
The word “Experience” as used in these procedures shall mean the number of years engaged in highway, transit, bridge and building construction or other public works contracts completed by the contractor for this Authority, other state highway and/or bridge departments, public building authorities, federal bureaus or similar agencies.
The contractor must be in business for at least one (1) year to be considered for prequalification.

D. "Prequalification Committee"


The term "Prequalification Committee" as used in these procedures shall mean a committee within the Authority consisting of the Assistant General Manager for Design and Construction or his/her designee as Chairperson, such members or their alternates as may be designated by the Chairperson of the Authority and a non-voting Recorder to be designated by the Chairperson of the Committee.
How the Prequalification Committee determines Single Project Rating Values:


  1. Single Project Rating Values




    1. Class of Work is >50% of Contract Value - When determining a contractor’s prequalification Single Project Rating (SPR) for a class of work, the committee will double the contract dollar amount if the class of work requested is 50% or more of the contract value.




    1. Class of Work is <50% of Contract Value - If the class of work is less than 50% of the contract value and the contractor performs greater than 50% of the total contract work, then the Committee prequalifies the contractor with double the values of the class of work.




    1. Responsible for <50% of Class of Work - If the contractor performs less than 50% of the work for a class of work, then the contractor would not receive prequalification for that class.

E. "Aggregate Bonding Capacity”


"Aggregate Bonding Capacity" shall be the highest total dollar amount of performance and payment bonds a surety will provide a construction contractor. The surety must be licensed and approved by the Massachusetts Division of Insurance and rated B+ or better by A.M. Best Company.
Support of a contractor's Aggregate Bonding Capacity must be presented as a total dollar amount in letter format on the provider’s letterhead. The letter must be signed by an authorized representative of the surety. Signing authorization, such as Power of Attorney, or Attorney-in-Fact, must accompany this letter.
F. "Current Capacity Rating”
"Current Capacity Rating” shall be the net difference between a Contractor's Aggregate Bonding Capacity and the dollar value of his/her current uncompleted work, regardless of its location and with whom it may be contracted. Contractors will not be eligible to bid on a contract when the Authority's estimated project value of the job exceeds the contractor's “Current Capacity Rating".
G. "Project Value”
Each project shall be given a "Project Value” derived from the Authority's preliminary cost estimate stated in round figures to the nearest hundred thousand.

H “Reference Checks”


Projects are subject to reference checks and must be completed to the satisfaction of the project owner to be considered for prequalification


  1. Presentations

Contractors with no MBTA experience will be invited to present their qualifications to the Prequalification Committee prior to prequalification. Contractors who lack recent MBTA experience may be invited to conduct interviews as requested by the Committee.


J. “Waivers”
One-time waiver requests will be reviewed on a case-by-case basis.

II. APPLICATION FOR PREQUALIFICATION
A. General
Any Contractor proposing to bid on work under the direction of the Authority, aggregating one million dollars ($1,000,000) or more, must furnish a notarized statement on forms provided by the Authority, setting forth financial data (as noted in Part IV "Financial Data" section of the Contractor Prequalification Statement), adequacy of plant and equipment, organizational structure, experience and other pertinent facts. The statement should be accompanied by Prequalification Rating Certificates from each state prequalified, if any have been issued.
Audited financial statements accompanying the Contractor Prequalification Statement must be for the most recent fiscal- year-ended. A full opinion audit must have been conducted in accordance with generally accepted auditing standards. At a minimum, financial statements should include auditor's opinion, Balance Sheet, income statement and footnotes.
Any significant change in the financial condition or the status of equipment and/or any change in the name or structure of the firm, officers or ownership, which occurs between the date of the audited financial statement and the filing date, must be reported to the Authority at the time of filing. The Authority reserves the right to demand additional information at any time.
For work aggregating under one million dollars ($1,000,000) post-qualification may be required. The information to be submitted after receipt of bids shall be similar to that required for prequalification. All bids submitted for work aggregating under one million dollars ($1,000,000) in excess of fifty thousand dollars ($50,000) will be accompanied by a letter of commitment from a surety company. This letter of commitment shall be in addition to any bid deposit.
All information furnished in any statement by a prospective bidder shall be held in strict confidence by the Authority and its agents, except where such information is required by statute, and/or regulations promulgated by applicable Federal or State agencies, and such information shall be used only to determine the prospective bidder's Aggregate Bonding Capacity and the Class of Work entitled to be undertaken in accordance with the procedures herein contained. No information contained in any such statement shall be imparted to any other person without the written consent of the prospective bidder.
Prequalification Statements shall be submitted yearly prior to the expiration date or written request for a time extension must be submitted and accepted by the committee.
B. Contractors
Contractors shall submit a completed Contractor Prequalification Statement accompanied by a Certificate from each State in which the organization performed work, stating the Rating, if any, issued by that State. All corporations must show proof of registration with the Massachusetts Office of the Secretary of State to do business in Massachusetts.
C. Joint Ventures
If recurrent joint venture bidding is desired, a combined Prequalification Statement of experience, principal personnel, plant and equipment, organizational structure, previous record, financial data and other pertinent factors, including the number, size and completion dates of construction jobs in this or other states presently under contract, shall be submitted. The joint relationship shall be considered in effect until one of the Contractors notifies the Authority that the joint relationship is concluded.
When a contractor has submitted a work history with a project that they participated in a joint venture, the contractor must only state the percentage of contract value of work that was self-performed. The committee will only evaluate its prequalification on the percentage of the contract that was performed by said contractor. The contractor will not receive prequalification ratings based on the entire contract value. If said contractor performed sixty (60%) of the contract then contractor will only be evaluated on 60% of the contract value.
D. Subsidiary Companies (When Parent Company Already Holds Prequalification Status)
In the event, that a prequalified parent company has formed or intends to form a subsidiary company with intent to prequalify, Prequalification Rating may be established for the subsidiary company subject to the following rule of procedure:
The subsidiary company shall be considered as an independent entity and shall be rated on the basis of its own independent financial resources, equipment, personnel, experience and the number, size and completion dates of construction jobs in this or other States presently under contract.
E. Time Limitation in Submitting Request for Prequalification.
Requests for Prequalification shall be submitted at least ten (10) calendar days proceeding the day set for opening of bids for work upon which a Contractor intends to bid or proposal submittal date. A request for prequalification will not be considered until a properly and correctly completed Contractor Prequalification Statement and financial data, including all necessary supporting data, has been submitted.
F. Class of Work Desired
Each prospective bidder shall indicate, in the place provided on page 3 in the Contractor Prequalification Statement, the particular class or classes of work upon which he/she desires to bid, but such indication shall not be binding upon the Authority in classifying a prospective bidder according to the facts disclosed in his/her Prequalification Statement. Classification will not be determined solely by the facts disclosed in his/her Prequalification Statement. For detailed description and identification numbers of all MBTA Classes of Work, please refer to Appendix 1.

G. Subletting Requirements

Please note the following language dictates the responsibility of the contractor for SUBLETTING OR ASSIGNMENT OF CONTRACT for MBTA Projects.

1. The Contractor shall give personal attention to the fulfillment of the Contract and shall keep the Work under control.



2. The Contractor shall not sublet, sell, transfer, assign, or otherwise dispose of the Contract or any portion thereof, or of the Contractor's right, title, or interest therein, without written consent of the Authority. If consent is given, the Contractor shall be permitted to sublet a portion thereof, but shall provide with the Contractor's own organization, Work amounting to not less than 50 percent of the original total Contract amount, except that any items designated in the Contract as "specialty items" may be provided by subcontract and the amount of any such specialty items provided by subcontracts may be deducted from the total amount in computing the amount of Work required to be provided by the Contractor's own organization. No subcontracts, or transfer of contract, shall in any case release the Contractor from liability under the Contract and bonds.

H. Contract Value
As stated above a Contractor must perform at least 50% of the work on a contract for that contractor to be considered for General Contractor prequalification
I. Classification Value
Contractor must complete 50% of the Class of Work to be considered for prequalification of that class except for Class 7 – Buildings. For Class 7 – Buildings, a contractor must provide DCAM certification with the work history.
>$500,000 – The Committee prequalifies Classification of Work valued at greater than $500,000.
Please do not submit any work value that is less than $500,000; it will not be considered for prequalification.

J. Class of Work
The value of the construction dollar amount of each class of work (Class 2 – 12 ) shall not exceed the contract amount. Class 1 work is the percentage (%) of the total contract amount that is performed by a contractor when operating in or around an operating rapid transit, light rail, commuter rail and freight right-of-way without causing disruption to service. Class 1A work is the percentage (%) of the total contract value that is performed by the contractor in or around the water.
Although a Contractor may possess and list many types of equipment in the Contractor Prequalification Statement for the purpose of establishing an Aggregate Bonding Capacity, only those types of equipment which will be useful in performing the contemplated work will be considered in determining the class or classes of work which the contractor shall be prequalified to undertake.
Contractors must show that it has appropriate and sufficient equipment available to satisfactorily perform the contemplated class or classes of work and that such equipment will not be leased or otherwise limited in use during the period of any contract, which he/she may be awarded. In lieu of actual equipment on hand, the Contractor may show current assets sufficient to provide the necessary equipment and may show that he/she will have sole jurisdiction over the equipment for a period of not less than twelve (12) months from the date of application. In addition to a complete description, a statement as to the condition of each piece of equipment shall be required. The Authority shall have the right to inspect all equipment in order to determine its operating condition and value.
K. Action on Requests for Prequalification
Each Contractor's Prequalification Statement shall be reviewed by the Prequalification Committee. This Committee shall analyze each statement, verify as it deems necessary the information set forth therein, determine the class(es) of work and review and approve the aggregate amount of work the prospective bidder shall be entitled to undertake. Whenever the Committee is not satisfied with the sufficiency of the answers contained in any Statement, it may require the Contractor to submit additional information, and, pending the filing of such additional information, the Authority may refuse to furnish such Contractor with an official proposal form for any duly advertised project. The Committee may require a personal interview with a prospective bidder when considering his/her qualifications for a Rating.
After review and analysis of a prospective bidder's Prequalification Statement by the Prequalification Committee, the Authority shall give the applicant written notice of its determination of his/her Aggregate Bonding Capacity and the class of work he/she shall be entitled to undertake.

III. RATINGS
A. General
Ratings shall be basically determined upon the Contractor's ability to properly finance the work as evidenced by bonding capacity, financial statements and supplementing documents, and on his/her competency and responsibility as indicated by the amount and condition of equipment, experience of principal personnel and previous record with this and other awarding authorities. Letters of credit shall not be accepted. An unlimited Aggregate Bonding capacity shall not be allowed. The resultant Ratings shall include the following component parts:
(1) Class of work

(2) Aggregate Bonding Capacity

(3) Single Project Limit, if assigned
The Authority, acting through its Prequalification Committee, reserves the right to establish a single project limit in a lesser amount than the Aggregate Bonding Capacity in cases where said committee has substantial and valid reason to believe that a prospective bidder is unqualified, either because of lack of experience or unsatisfactory performance on a previous contract, to satisfactorily perform a contract in the full amount of his/her Aggregate Bonding Capacity.
B. Duration of Prequalification Ratings
Prequalification Ratings shall remain in effect for not more than sixteen months following the date of the contractor's balance sheet used in the prequalification statement.
C. Revision of Prequalification Ratings
Whenever the Authority has substantial reason to believe that the condition of a contractor previously prequalified is less favorable and job performance is not satisfactory than at the time of its last application, a new Prequalification Statement shall be requested in writing stating the reason therefor. If the requested statement is not filed within thirty (30) days from date of notice, the current Ratings shall be considered forfeited, and the Contractor concerned will not be permitted to bid until a new Contractor Prequalification Statement has been received and acted upon by the Authority.
Prequalification could be subject for review and loss of prequalification, reduction of ratings if job performance or safety performance is not satisfactory and subject of losing the privilege to bid on future MBTA contracts.
Qualification Ratings shall be modified whenever it is determined that a Contractor does not have sufficient equipment, or sufficient assets to provide necessary equipment either through purchase or lease agreements, or his/her performance is unsatisfactory.
Requests by contractors for the revision of Prequalification Ratings will be considered by the Authority at any time provided a new Prequalification Statement is submitted. Such statements must be submitted in proper form at least ten (10) calendar days prior to a bid opening in order to receive consideration for that bid opening.

If at any time subsequent to filing, any significant change occurs in the financial condition or the status of equipment and/ or any change in the name or structure of the firm, officers, principal employees or ownership, a written notice shall be given to the Authority, whereupon a new application for prequalification may be required.

If an individual or member of a partnership withdraws cash, securities, or any assets subsequent to the filing of a financial statement with the Authority, he/she shall give written notice to the Authority of such withdrawals; the Authority will then adjust the financial Rating of the individual or partnership accordingly.
IV. PROPOSAL FORMS
A. Requests for Proposal Forms
All prospective bidders who wish to bid on work to be awarded by the Authority must submit a completed "Request for Proposal Forms” to the Authority, accompanied by cash, bank check, certified check or money order in the amount stated in the Notice to Bidders, made payable to the Massachusetts Bay Transportation Authority. Prospective bidders are required to submit a letter to the Manager of Contract Administration listing the names of all individuals authorized to sign the "Request for Proposal Forms”. The letter is to be signed by a member or officer of the firm together with his/her title.
Unless a prospective bidder has “prequalified”, he/she shall not be entitled to bid on work, the value of which when added to the value of his/her uncompleted work already under contract with the Authority aggregates $1,000,000 or more. The Prequalification Committee can consider requiring prequalification for projects under $ 1,000,000 for Class 1 – General Transit Construction projects or if the proposed work has a safety element or potential risk to MBTA operations. The Committee has the right to evaluate a contractor’s ability to work on any project that is within 25 feet of the active right of – way.
A Contractor may take out more than one proposal form at a time, to be opened either on the same date or on subsequent dates, providing that no one single project exceeds his/her current capacity rating. Any proposal, the project value of which places the bidder in a position of exceeding his/her current capacity rating, shall be refused him. He/She shall be entitled to receive all other proposals whether opened on the same date or on subsequent dates.
Two or more Contractors who have been prequalified may combine all or a portion of their assets for occasional bidding purposes, by filing with the Authority a completed joint “Request for Proposal Form," stating on an attached separate sheet the portion of each of their assets to be considered jointly. The sum of these will determine the Aggregate Bonding Capacity of the joint ventures. One of the joint ventures must be prequalified in the class of work for which they intend to submit bids. (See Section II, c.).

B. Action on Requests for Proposal Forms


The Authority shall act upon a “Request for Proposal Forms” within five (5) business days following receipt by the Director of Contract Administration, excluding a Saturday, Sunday or holidays.
Prior to the issuance of a proposal form, consideration will be given to the number of projects the prospective bidder has under contract, the state of progress thereon, and his/her “Current Capacity Rating" as determined by deducting the total dollar value of uncompleted work shown in the "Request for Proposal Forms” from his/her Aggregate Bonding Capacity.
Each proposal form shall have an identifying number and shall be non-transferable. A bid submitted on a proposal form issued to another Contractor shall be rejected.
C. Non-issuance of Proposal Forms
A proposal form shall not be issued to a prospective bidder:
(1) If the Authority's Project Value (P.V.) for the particular project upon which he/she desires to bid exceeds his/her "Current Capacity Rating," or
(2) On non-Federally-aided projects, if the prospective bidder has been adjudged guilty of any irregularity in connection with public works before a court of competent jurisdiction. (A specific time period during which a proposal will not be issued shall be established following such court action. Should an appeal be taken, the period of disqualification shall continue until the judgment is reversed in which event the period of disqualification shall end).
(3) On Federally-aided projects, if the prospective bidder:
(a) has been established as being unacceptable for employment as provided by the applicable regulations issued by the Secretary of Labor, United States Department of Labor.
(b) appears on the U. S. Comptroller General's Consolidated List of Persons or Firms Currently Debarred for Violations of Various Public Contracts Incorporating Labor Standards Provisions.
The Authority may also refuse to issue a proposal form if the Prequalification Committee determines that:
(1) The prospective bidder is making unsatisfactory progress or performing work which is substantially unsatisfactory on projects already under contract.
(2) The prospective bidder has performed unsatisfactory work on prior contracts or his/her performance record has been unsatisfactory on prior contracts.
A prospective bidder shall be notified in writing of the refusal by the Authority to issue a proposal form within five (5) business days, excluding a Saturday, Sunday or holidays, following receipt of request for proposal form by the Director of Contract Administration.
After receiving notification of refusal to issue a proposal form, the prospective bidder may make written request for a review by the Prequalification Committee. A request for a review shall set forth the prospective bidder's arguments for a revision of the decision. The Prequalification Committee shall give a written decision within seven (7) business days of receipt of the prospective bidder's request. In either case, the decision shall be final and binding, subject to any rights of the prospective bidder to a judicial review.
V. MISCELLANEOUS
A. Order of Bid Openings
Proposals shall be opened and read in the order of decreasing dollar values, commencing with the highest "Project Value” as set forth in section I, g.
B. Bid openings
A Contractor may submit proposals for more than one project to be opened on the same or subsequent days. However, if he/she is found to be the low bidder on one project, all subsequent bids which place him in the position of exceeding his/her Current Capacity Rating shall be subject to review. The Authority reserves the right to accept or reject any such bids when such action is determined to be in the best interest of the Authority.

C. Right to Reject Bids


Nothing in these procedures shall be construed as depriving the Authority of the right to reject any bid when it is found that the bidder has exceeded his/her current capacity rating or when, in the opinion of the Authority, circumstances and developments have changed the qualification or responsibility of the bidder.
D. Rights of a contractor for Appeal
A Contractor or prospective bidder who is aggrieved by a decision or determination of the Authority may file a new application for prequalification at any time, or within fifteen (15) calendar days after receiving notice of such decision or determination, may make written request for a review by the Prequalification Committee. A request for review shall set forth the argument for a revision of the decision. The Prequalification Committee shall render a decision within fifteen (15) calendar days following receipt of the request. The previous Rating or decision shall remain in effect until the Prequalification Committee renders a decision in writing on the appeal. The decision of the Prequalification Committee shall be final and binding, subject to any rights of the contractor or prospective bidder to a judicial review.
