due, and, as liquidated damages, an additional amount equal to 20% of the unpaid contributions as determined by

return receipt requested, the said Employer shall be required thereafter for the remaining term of this Agreement
to furnish a bond for double the amount required in Section I, and if the said Employer is thereafter delinquent at

them, or the Administrator, have the authority to direct, in writing, an Employer that is unbonded and/or on the

within three (3) calendar days from the close of the work week, i.e., for a work week ending on Tuesday, the

Trustees, as to any Employer so required to make Fund payments within three (3) days, may initiate arbitration
and/or any other remedy available to them, at any time after the third calendar day from the close of the work

than three (3) times during the term of this Agreement and/or issues a check to the Funds which is returned

through Chairman and Co-Chairman or a sub-committee of Trustees designated by them, have the authority to
direct an Employer to make Fund payments by means of Certified Check, Bank Check, or Money Order. Any
Employer that issues a check to the Funds which is returned for any of the aforementioned reasons, shall be
charged a bounced check inconvenience fee by the Fund Office in the amount of one hundred dollars ($100)
unless the Employer can demonstrate that the bounced check was caused by a bank or third-party error and due to
no fault of the Employer. Any Employer that is at fault for more than one bounced check to the Fund Office shall
forfeit their check writing privileges and must submit payment via ACH or wire transfer. Any Employer that
fails to meet a three (3) day payment schedule that may be directed pursuant to this Paragraph, and/or fails to pay
by Certified Check, Bank Check, Money Order, ACH or Wire Transfer when so directed, shall be deemed
delinquent within the meaning of Rule IV, Section II, and the Union may refuse to permit employees to work for
19
such Employer.
Reporting of Fund payments by employee’s name shall be submitted at the same time as payments are due.
All hours reporting will be entered by the contractor on the employer portal section of www.steamfitters.com.
In addition to any other action the Funds may be empowered to take, the Funds may bring an action pursuant
to Sections 502 (G) (2) and 515 of the Employee Retirement Income Security Act of 1974, as amended, to
enforce the Employer’s obligation to make contributions. In any action under the preceding sentence in which
judgment is awarded in favor of the Funds, such judgment shall award the Funds: the unpaid contributions, and
interest at the Maximum Rate of Interest, and as liquidated damages an amount equal to 20 percent of the said
unpaid contributions as determined by the court, and reasonable attorney’s fees, audit fees and costs of the action,
and such other legal or equitable relief as the court deems appropriate. Nothing in the foregoing two sentences
shall be construed as a waiver or limitation on the Funds’ or the Trustees rights to enforce an Employer’s
obligation to contribute in any other type of proceeding against the Employer and/or its shareholders and/or its
officers.
In the event an Employer is delinquent hereunder as defined in Rule IV, Section II, the Funds, in their sole
discretion, may initiate arbitration proceedings to obtain appropriate relief. The parties specifically agree that
any claim made by the Funds based upon any such delinquency may be initiated by the Funds upon fourteen (14)
days written notice of intention to arbitrate by registered mail or certified mail to the last address of the employer
on record with the Fund Office, an Arbitrator as the Board of Arbitration may from time to time select, to be
settled by arbitration in accordance with the Voluntary Labor Arbitration Rules of the American Arbitration
Association (“AAA”), except as otherwise provided herein and judgment upon the award rendered by the
Arbitrator may be entered in any court having jurisdiction thereof and shall be final and binding upon the parties.
Should the Board of Arbitration fail to reach mutual agreement on the selection of an Arbitrator, the parties shall
utilize AAA to select an Arbitrator. Should the Employer fail to appear, together with his payroll records for the
period of delinquency in question, the Arbitrator may find against the Employer by default. In any case in which
the Arbitrator finds that the employer is indebted to the Funds, the award shall include: the unpaid contributions,
and interest on unpaid or tardily paid contributions at the Maximum Rate of Interest; and as liquidated damages
an amount equal to 20% (twenty percent) of the unpaid contributions as well as any sums due pursuant to Section
IV of this Rule; and reasonable attorney’s fees, audit fees and costs of collection, and such other legal and
equitable relief as the Arbitrator deems appropriate. It is specifically agreed by the Employer that in any case in
which the Funds serve a notice of intention to arbitrate (or demand for arbitration) which results in a notice of
hearing being issued by the Arbitrator, contributions for all weeks which are claimed as due by the Funds as of
the notice of intention to arbitrate as well as contributions for all weeks claimed as due by the Funds through the
date of the arbitration hearing or adjourned date, if any shall be subject to such arbitration. Once the notice of the
hearing is issued, payment of the sums claimed in the notice of intention to arbitrate and all sums claimed as
becoming due thereafter in accordance with the preceding sentence, will not be deemed to have been made until
the Fund Office receives such sums in the form of cash, certified check, or an uncertified check which the Fund
Office determines has cleared prior to the arbitration hearing; the Fund’s judgment as to the time of clearing of a
check shall be conclusive. An Employer to whom a demand for arbitration has been mailed shall pay
cancellation fee for legal, administrative and/or arbitration costs as follows: if all fringe benefits claimed in the
demand for arbitration are paid, with interest, prior to the arbitrator mailing a notice of hearing, the cancellation
fee is TWO HUNDRED DOLLARS ($200); if the notice of hearing has been issued by the arbitrator, and all
fringe benefits claimed by the Funds as due as of the date of hearing have been paid, with interest, the
cancellation fee is FOUR HUNDRED DOLLARS ($400), if paid more than twenty-four (24) hours prior to the
scheduled starting time of the hearing and SIX HUNDRED DOLLARS ($600) if paid prior to, but less than
twenty-four (24) hours before the scheduled starting time of the hearing. Initiation of the aforesaid arbitration
procedure shall not preclude the Funds from pursuing any other remedy or remedies available to them including
other remedies against the Employer and/or its officers and/or its shareholders. It is expressly understood and

If the Employer fails to attend the sub-committee meeting described in Section I, second paragraph, or if it
fails to attend a meeting of the full Board of Arbitration referred to in Section I, third paragraph, the subcommittee or the full-committee, as the case may be, may issue a decision by default. If the subcommittee
declines to issue a written decision in an instance when the employer fails to appear, the full committee shall then
meet. If the employer fails to appear at the full committee meeting and the committee fails to render a decision,
the union may seek appointment of an arbitrator.

within two (2) working days thereafter render his decision, and said decision shall be final and binding upon both
parties hereto.
ARTICLE VIII
JOINT ARBITRATION PLAN
It is further mutually agreed that both parties to this Agreement shall abide by a Joint Arbitration Plan that
23
may be agreed upon by representatives of the several employers’ associations and a majority of the unions of the

It is mutually agreed between the parties hereto that in event of disputes between trades, and disputes relative
to question of jurisdiction of trade, the parties will abide by previous decisions as to jurisdiction published in the
latest issue of the B.T.E.A. Handbook, commonly known as “The Green Book.”
It is mutually agreed between the parties hereto that disputes between trades, and disputes relative to
jurisdiction of trade not covered by decision in the latest issue of the B.T.E.A. Handbook, commonly known as
“The Green Book”, shall be adjusted in accordance with the principles of the New York Plan for the Settlement
of Jurisdictional Disputes as set forth in the Joint Arbitration Plan of the New York Building Trades as adopted

as stated in the preceding paragraph the members of the Union shall remain at work on the project without
change in status.
ARTICLE IX
TERM OF THIS AGREEMENT
It is further mutually agreed that no change in this Agreement shall be asked for by either party hereto, to
take effect prior to the first day of April 2027 and not then unless notice by the Association asking for such
change is given to the other Association on or before the 31st day of October next preceding the first day of April
2027. Such notice shall be given in writing by Secretary of one Association to Secretary of the other
Association, and shall state specifically all changes desired, and written receipt therefore shall be evidence of
such notice.
In case no notice is served by either Association on or before October 31, 2026 then this Agreement shall
continue in effect from year to year with right reserved for either party to serve notice on or before any 31st day
of October in any year for any desired change to take effect on the following first day of April.
ARTICLE X
It is understood and agreed that this Agreement is based upon the Principles for Trade Agreements as set
forth in the printed annex to this Agreement, and nothing in the Rules of the Enterprise Association attached
hereto, or within this Agreement, shall be interpreted to contradict or nullify any of the said Principles.
It is agreed that if Enterprise Association furnishes Steamfitters to anyone upon more favorable terms or
conditions than those contained herein, then this Agreement shall automatically be amended to incorporate such
more favorable terms or conditions.
It is understood and agreed that in case any provisions of this Agreement shall be found to be contrary to law,
such finding shall not in any way affect the other provisions of this Agreement, which shall, notwithstanding,
continue in full force and effect, and the parties shall within ten (10) days after receipt of written notice by one
party from the other, negotiate in an attempt to arrive at an appropriate substitute provision in light of such ruling.
In the event of change of applicable Federal laws affecting this Agreement, by virtue of which change it shall
become legal for the Enterprise Association to demand that only members of Enterprise Association be employed
in the performance of work under its jurisdiction, or to institute what is commonly known as the “closed shop”,
the Contractors’ Association agrees that in such event and on the giving of ten (10) days’ notice to the
Contractors’ Association by Enterprise Association in writing by registered mail, this Agreement shall be deemed
amended to the end that on and after the conclusion of the said ten (10) day period only members of the
Enterprise Association shall be employed by the Contractors’ Association in their performance of work coming
within the jurisdiction of Enterprise Association and only members of the Metal Trades Branch of Local Union
638 shall be employed in the performance of service work more particularly described in Rule XVI of this
Agreement.

THE PRINCIPLES FOR TRADE AGREEMENTS
As referred to in Article X of the agreement dated April 1, 2024 between the Mechanical Contractors
Association of New York, Inc., and the Enterprise Association of Steam, Hot Water, Hydraulic, Sprinkler,
Pneumatic Tube, Ice Machine and General Pipefitters of New York City and Vicinity, Local Union No. 638 of
United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United
States and Canada.
PRINCIPLES UPON WHICH TRADE
AGREEMENTS SHOULD BE BASED
1. There shall be no strikes or lockouts or stoppage of work, neither shall members of a union collectively leave
the work of a member of the Building Trades Employers’ Association. Trade agreements made by the Employers’
Associations, members of the Building Trades Employers’ Association, and trade unions shall provide that all
disputes arising in the trade shall be settled by trade boards of arbitration, with an umpire if necessary, and the
decisions of trade boards and umpires shall be final and binding.
2. There shall be no agreement providing for discrimination against building materials, raw or manufactured.
3. The amount of work a man may perform shall not be restricted by a union nor by the representative, officers
or members of a union; and the use of machinery, tools, appliances or methods shall not be restricted or
interfered with.
4. The employer shall be at liberty to employ and discharge whomsoever he sees fit; and the members of the
unions shall be at liberty to work for whomsoever they shall see fit.
5. The foreman shall be the agent of the employer and shall not be tried for any of his acts as foreman without
due notice of the trial, accompanied by a written statement of the charges against him, being given to the Joint
Trade Board.
6. The trade associations and unions shall jointly maintain a system which will provide an adequate force of
skilled mechanics. The Apprenticeship Plan of the New York Building Congress is endorsed.
7. Overtime shall not be worked, except when unavoidable.
8. There shall be no provision, in any trade agreement, having for its object the collection of debts.
9. There shall be no provisions, in any trade agreement, which will prevent the doing of cutting by the trade
which installs the work for which the cutting is done.
10. Unskilled work, as defined in the trade agreements, may be performed by the laborers or helpers. The work
that has been heretofore recognized to be in the possession of a trade shall not be submitted to arbitration, unless
possession is claimed by a party or parties to a jurisdiction of trade dispute.
11. All contractors party to this agreement, agree to be bound by decisions of the United Association, the
B.T.E.A. of New York City or the National Joint Board.
12. The Employers recognize that the Union had a legitimate goal of preserving bargaining unit work
opportunities for the Steamfitters who are or have been regularly employed under the Trade Agreement.
The Employers also recognize that the above goal can sometimes best be achieved through the flexibility of
modifying work rules (other than those pertaining to wages, benefit fund contribution rates, or apprentice ratios)
for a particular project.
Therefore, if modifications are approved by the Joint Trade Board to preserve bargaining unit work, the
Employers agree that they will not invoke the Most Favored Nations Clause, Article X, second paragraph, based
29
on the Trade Board’s modification of Work Rules (other than those pertaining to wages, benefit fund contribution
rates, or apprentice ratios) for a particular job project.
SUPPLEMENT ON APPRENTICESHIP TRAINING
When Apprentices are out of work, a maximum of one apprentice may be hired to work alongside
two Journeymen Steamfitters per contract on a jobsite with approval of the Union. In all instances, a
contractor shall ensure compliance with the minimum number of apprentices established in Rule II, Section
IIIA as well as compliance with maximum apprentice ratios established by NYS Department of Labor. The
Supplement is for a one-year period; the Supplement is to be evaluated by the Joint Trade Board and can be
extended for one (1) year periods only if agreed to by the Joint Trade Board (there shall be no arbitration to
resolve any lack of agreement).
An out of work Apprentice may be requested by the Employer and, if available, sent to the jobsite.
All requests are subject to the approval of the Union. Any Apprentice hired under this Supplement shall be
assigned overtime if it is assigned to the Journeymen Steamfitters supervising that Apprentice. Employers
requesting an Apprentice for hire under this Supplement shall be current in their employee benefit
contributions and not have a pending matter before the Joint Board of Arbitration or have been found in
violation of the Trade Agreement for a period of one (1) year prior to the request.
NEW SUPPLEMENT FOR LONG ISLAND
AND RESIDENTIAL WORK IN NEW YORK CITY
For jobs bid on or after April 1, 2024, the terms of the Public Works Supplement will be used:
1. for all jobs on Long Island, NY except power generation jobs,
2. for residential jobs in Brooklyn, Queens, the Bronx, and Staten Island, NY,

others as agreed to by the Joint Trade Board); residential building does not include nursing homes, assisted living
facilities, hospitals, college dormitories, or hotels (other than budget/economy hotels).
A residential building may include up to two floors of offices, stores, and/or restaurants; this Supplement
shall not apply to those floors, unless included in the base building contract.
The most favored nation’s provision of the Trade Agreement, Article X, second paragraph, will not apply to
or be invoked as to this Supplement.
This Supplement shall not apply to, or be invoked as to any job bid prior to April 1, 2024, and this
Supplement shall not apply to any job governed by a Project Labor Agreement bid prior to April 1, 2024.
