Operating Engineers Local 513

The Pension Fund of Operating Engineers Local 513 was established in 1963 as a multiemployer defined-benefit plan covering members of the International Union of Operating Engineers Local 513, which represents crane, bulldozer, and heavy-equipment operators in the St. Louis metropolitan area and eastern Missouri. The fund is funded through collective-bargaining contributions from signatory contractors and employer associations, including the SITE Improvement Association and the Associated General Contractors of Missouri. Unlike single-family offices or university endowments, the plan's liability stream is tied to the working lives of skilled construction tradespeople, which shapes a conservative, cash-flow-aware investment posture. The fund allocates across public equities, fixed income, real estate, private equity, private credit, and hedge funds. Real estate exposure is notable: the plan directly owns its union hall and fund office in Bridgeton and a 499-acre training center in Silex — revenue-generating assets that double as operational infrastructure for apprenticeship programs. On the private-markets side, the fund is known to participate in fund commitments, co-investments, and secondaries across buyout, venture, mezzanine, and special-situations strategies. The pension maintains relationships with labor-aligned investment consultants and fits within the ecosystem of Taft-Hartley plans that collectively represent over $1 trillion in US retirement assets. Total assets are not publicly disclosed by the fund, but Altss estimates the portfolio at approximately $694 million. The plan operates alongside sister funds — the Annuity Fund, Welfare Fund, and Journeyman & Apprenticeship Training Fund — all administered from the Bridgeton headquarters. The fund participates in regional economic-development networks, including the Hawthorn Foundation and Missouri Partnership, reflecting a dual mandate: fiduciary returns for beneficiaries and broad-based economic growth in the St. Louis construction corridor. No recent Form 5500 filings have been surfaced with named investment staff. The fund's structural differentiator is its integration with a vertically organized labor ecosystem. Unlike a generic state pension, the Local 513 plan sits at the center of a tight network of union contractors, training facilities, and collectively bargained contribution rates. This proximity to both the workforce and the signatory employers means investment policy must account for countercyclical contribution risk — when construction slows, contributions slow — a constraint that pushes the portfolio toward liquidity-aware, yield-oriented strategies not always seen in comparably sized public plans.
