Construction Retirement Plans

Why Industry Matters for Retirement Planning

The American retirement system has bifurcated along industry lines over the past forty years. Traditional pension-heavy industries, manufacturing, utilities, transportation, public education, retain a meaningful population of defined-benefit plans, often as legacy structures with closed enrollment for new hires. Industries that grew up after the 1981 Internal Revenue Code change that authorized 401(k) plans, technology, financial services, professional services, are nearly entirely defined-contribution. Some industries, notably construction and entertainment, run multi-employer pension funds that pool contributions across employers and unions; these funds appear in Form 5500 as separate filings with their own asset bases and funded-status histories.

PlainRetire's industry pages organize plans by their reported NAICS code (when present) or, when NAICS is missing, by an industry label derived from the plan sponsor name. The resulting view lets a participant or analyst see, for instance, the prevalence of ESOPs in employee-owned manufacturers, the asset concentration of financial-services 401(k) plans, or the participant counts of multi-employer health-and-welfare-plus-pension Taft–Hartley funds in transportation.

What Industry Aggregates Can and Cannot Tell You

Industry-level aggregates are useful for spotting patterns: which sectors have larger plans on average, where defined-benefit plans persist, which industries have higher employer contribution rates as a share of payroll. They are less useful for decisions about a specific employer's plan, because within-industry variation is often as large as between-industry variation. A small technology firm may run a plan that looks more like a manufacturing plan than a tech plan; a manufacturing conglomerate may run a plan that looks more like a financial services plan. When evaluating a specific plan, drill from the industry page into the plan detail page and inspect plan-specific characteristics, vesting schedule, employer match, investment menu, fees, rather than relying on the industry average.

Industry classifications can drift across years as DOL updates the NAICS taxonomy or as sponsor businesses change primary activity. PlainRetire uses the classification reported in the most recent accepted filing and preserves earlier classifications in the historical record on each plan detail page.
