Most public agencies do not realize this yet, but consultant construction inspectors in Southern California are quietly becoming $230 per hour resources. Construction costs are rising everywhere. Materials, labor, and equipment get most of the attention. But CM&I services are increasing as well, driven by California-driven prevailing wage increases that many agencies are only now seeing in their RFP responses. In August 2025, California DIR raised prevailing wage for Group 2 construction inspectors to $101.27 per hour, with scheduled predetermined increases to $106.27 in July 2026 and $110.77 in July 2027. A critical detail that is often missed: prevailing wage is tied to the project advertisement date, not construction start. Projects advertised after August 2025 use the new rates for the entire project duration. Projects already in procurement under the old rates are the last ones agencies will see at prior pricing. Here is how CM&I billing rates are built: Start with prevailing wage ($101.27). Subtract employer-paid fringe benefits (health, retirement, PTO), roughly $15 per hour, leaving ~$86 in adjusted base wage. That base wage is then multiplied by the firm's indirect cost rate, a standard methodology used by Caltrans and most public agencies to cover firm overhead, supervision, office space, vehicles, insurance, and administration. Using the Caltrans Safe Harbor multiplier of 2.4 as a common benchmark: Today: $86 base x 2.4 = ~$206/hr loaded July 2027: $96 base x 2.4 = ~$230/hr loaded This multiplier effect is what most agencies do not see coming. A $10/hr increase in prevailing wage becomes ~$24/hr in billing rates once overhead is applied. Most contracts allow ~3% annual escalation. Loaded CM&I costs are increasing over 10% annually through 2027. For public agencies budgeting future CM&I work, the practical takeaways are straightforward: Plan for 10 to 15% cost increases on CM&I scopes. Incorporate wage pass-through language into new agreements so rate adjustments are transparent and expected rather than surprising. And when evaluating proposals, ask firms how they manage overhead, not just what their rate is. Prevailing wage is fixed by the state. Overhead is not. Firms that operate efficiently, like the team at RE Services, can deliver the same quality at meaningfully lower loaded rates without cutting corners on service. Construction costs are not just increasing. They are accelerating. And as contractor margins get squeezed by the same pressures, the temptation to cut corners on workmanship grows. This is when independent CM&I oversight matters most. Agencies that reduce inspection coverage to offset rising CM&I costs are trading a known expense for a much larger unknown one. The inspector is not just a line item. The inspector is the last line of defense on public infrastructure.
