Other Heavy & Civil Engineering Construction: retirement plans
Plans whose sponsor entered this principal business activity code on Form 5500.
Form 5500 information is as filed by the plan administrator with the Department of Labor and may be amended. Figures reflect the plan year shown, not current balances. The business code is chosen by the filer from the list in the Form 5500 instructions.
304 retirement plans in other heavy & civil engineering construction with 100 or more participants filed Form 5500 for plan year 2024 (274 defined contribution, 30 defined benefit). All Form 5500 pension filers in the group reported 700,637 participant records and $64.2B in net assets.
The median defined contribution plan held $54,176 per participant, close to the national median of $53,031, and its employer put in $2,824 per active participant (national: $2,174). Among plans reporting Schedule C compensation the median was $144 per participant against $123 nationally.
Employers contributed $2.92B and participants $838M during the year, and the plans paid out $4.72B in benefits.
In 2009 the same group numbered 338 plans with $25.4B; by 2024 it was 304 plans (down 10%) and $64.2B (up 153%). From plan year 2023 the 100-participant line counts participants with account balances, which moved many plans to the short form.

Questions and answers
How many retirement plans are there in other heavy & civil engineering construction?
304 plans with 100 or more participants filed Form 5500 for plan year 2024, out of 429 pension plans on the full form. Smaller plans file Form 5500-SF and are counted separately where shown.
What is the typical 401(k) balance in other heavy & civil engineering construction?
The median defined contribution plan reported $54,176 in net assets per participant (middle half of plans: $29,449 to $109,395); nationally it was $53,031. This is a plan-level average that includes former employees, not a typical person's balance.
What do employers contribute in other heavy & civil engineering construction?
The median defined contribution plan received $2,824 in employer contributions per active participant, against $2,174 nationally. Plans with no employer contribution are included at zero.
What are average 401(k) fees in other heavy & civil engineering construction?
Among defined contribution plans that report any Schedule C compensation, the median was $144 per participant and 0.28% of net assets (nationally $123 and 0.26%). Schedule C leaves out fund expense ratios and fees the employer pays, so it understates total cost.
Where does this come from?
Form 5500 annual reports in the EBSA research files, with filings received through 24 Aug 2026. Medians are computed by this site across plans with 100 or more participants.
