Plumbers Local #12
Plumbers Local #12 was chartered in 1890 and has represented plumbers, pipefitters, and HVAC technicians across the Boston metropolitan area for over 130 years. The union is an affiliate of the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry, and negotiates wages, benefits, and working conditions with the Greater Boston Plumbing Contractors Association, the signatory contractor group. The pension fund operates as a multiemployer defined-benefit plan under federal Taft-Hartley rules, jointly governed by union and employer trustees. The fund invests across a diversified institutional portfolio to meet long-dated liabilities. Its investment strategy includes significant allocations to private equity secondaries, real assets, and infrastructure, reflecting a preference among labor-affiliated plans for cash-yielding and inflation-hedging exposures. The plan participates in fund commitments and direct co-investments through external managers, with a geographic footprint concentrated in US markets, particularly the Northeast. In 2023, the plan committed $40 million to a middle-market secondaries vehicle managed by HarbourVest, a Boston-based private equity firm, as part of a broader effort to reduce the J-curve drag on portfolio returns. The union's training infrastructure is a differentiator. The Plumbers Local 12 Union Hall and Training Center on Massachusetts Avenue in Dorchester, Boston, houses a five-year apprenticeship program. Revenue from the training fund's assets — separate from the pension — complements the union's operational budget. The plan engages with the Massachusetts Building Trades Council and maintains a relationship with former Boston Mayor and US Secretary of Labor Martin J. Walsh, a longtime labor ally and former head of the Boston Building Trades. Walsh's career began with Laborers' Local 223, and his administration supported project-labor agreements that drove union pension contributions. The union's foundational commitment to member training creates a structural integration uncommon among Taft-Hartley plans. The proximity of the training fund's assets to the pension fund's governance allows coordinated investment in workforce development that directly supports the signatory contractors whose contributions fund the retirement plan. This closed loop — training future members, placing them with contributing employers, and investing resulting contributions for retirement — distinguishes the Local 12 plan from peer multiemployer funds that lack integrated labor-supply infrastructure.

Frequently asked questions
How is the Plumbers Local #12 pension fund structured?
The fund is a multiemployer defined-benefit plan governed by a board of trustees — half appointed by Local 12 and half by the Greater Boston Plumbing Contractors Association. It operates under the Employee Retirement Income Security Act (ERISA) and Taft-Hartley provisions, with contributions remitted by signatory contractors based on collective bargaining agreements covering hourly wages and benefits.
Which investment consultants advise the fund?
Public records of multiemployer plan consultants are not consistently disclosed, and Local 12's most recent filings do not name a specific investment consultant. Many Massachusetts building trades funds retain regional institutional consultants such as Segal Marco Advisors or Meketa Investment Group, but Local 12's current advisory line-up has not been publicly confirmed.
What role do secondaries play in the portfolio strategy?
Secondary commitments represent a recurring allocation, as evidenced by the plan's $40 million commitment to a HarbourVest secondaries fund in 2023. The strategy reduces the J-curve effect associated with primary fund commitments by acquiring seasoned LP interests, which can begin distributing sooner and provide a shorter path to net cash flow — important for a maturing multiemployer plan managing liquidity needs.
Does Plumbers Local #12 invest directly in real estate?
The union holds real estate assets including its Dorchester training center and union hall, but those are held outside the pension fund. The pension plan invests in real assets through commingled funds and does not appear to pursue a separate-account direct property strategy, based on available portfolio disclosures.
How is the training fund related to the pension plan?
The Plumbers Local 12 Education Fund is a separate legal entity, funded by collectively bargained employer contributions distinct from pension contributions. It finances the five-year apprenticeship program, instructor salaries, and facility operations at the Massachusetts Avenue training center. Though governed separately, the training pipeline is economically linked — it produces qualified workers who generate future pension contributions.
What is the fund's posture on infrastructure investing?
The portfolio includes infrastructure allocations, which align with the plan's long-duration liabilities and inflation-sensitivity requirements. The fund accesses infrastructure through external managers, and has not publicly disclosed direct or co-investment structures in the asset class. Infrastructure commitments are typical for building trades plans given their alignment with the construction and maintenance sectors.
