New York state could save 15% on public works projects by using private-sector engineers versus public employees. A new report, NYSDOT Engineering Costs: In-House vs. Outsourced Engineering compares New York State DOT (NYSDOT) employee costs to the private sector's, including salaries (adjusted for weekly work hours), medical insurance, pension plans, workers' compensation, unemployment, social security insurance, and overhead.

The study by the Polytechnic Institute of New York University calculates the cost for a private-sector New York engineer at around $186,000/year, and between $207,000 and $232,000 for a NYSDOT engineer. The difference is attributed to the expense of the benefits, paid time off, and fewer work hours per week in the public sector.
