Other Specialty Trade Contractors (including site preparation): 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.
1,028 retirement plans in other specialty trade contractors (including site preparation) with 100 or more participants filed Form 5500 for plan year 2024 (889 defined contribution, 139 defined benefit). All Form 5500 pension filers in the group reported 1,640,381 participant records and $124.8B in net assets.
The median defined contribution plan held $39,696 per participant, well below the national median of $53,031, and its employer put in $2,326 per active participant (national: $2,174). Among plans reporting Schedule C compensation the median was $144 per participant against $123 nationally.
Employers contributed $6.14B and participants $1.72B during the year, and the plans paid out $9.74B in benefits.
In 2009 the same group numbered 942 plans with $40.8B; by 2024 it was 1,028 plans (up 9%) and $124.8B (up 206%). From plan year 2023 the 100-participant line counts participants with account balances, which moved many plans to the short form.

Plan year is the year in which the plan year began. The drop in large plans from 2023 follows a rule change: the 100-participant line now counts participants with account balances, so many plans moved to the short form.

Questions and answers
How many retirement plans are there in other specialty trade contractors (including site preparation)?
1,028 plans with 100 or more participants filed Form 5500 for plan year 2024, out of 1,888 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 specialty trade contractors (including site preparation)?
The median defined contribution plan reported $39,696 in net assets per participant (middle half of plans: $21,126 to $74,627); 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 specialty trade contractors (including site preparation)?
The median defined contribution plan received $2,326 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 specialty trade contractors (including site preparation)?
Among defined contribution plans that report any Schedule C compensation, the median was $144 per participant and 0.36% 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.
Provenance
