Construction firms deploying flight risk scoring see 25-40% reductions in unplanned turnover within the first 12 months, translating to $150K - $400K in recovered productivity and avoided rework costs depending on firm size and project mix. More directly: targeted retention interventions prevent 3-5 critical departures per year at a mid-sized firm, each worth $80K - $120K in avoided schedule delays and margin erosion. Safety incident rates drop 15-20% because experienced crew leads and superintendents stay longer, maintaining institutional knowledge of job site protocols. Schedule variance improves 10-15% as project manager continuity reduces RFI response delays and change order friction. Bid accuracy improves 8-12% because estimators remain longer and refine their models against actual project outcomes rather than cycling through new hires still learning your firm's cost structure.
ROI compounds over 12 months because retention improvements are cumulative. Month 1-3, you prevent 1-2 critical departures and see direct margin recovery on active projects. Month 4-6, reduced turnover stabilizes crew continuity, so safety incident rates flatten and schedule variance tightens - lower insurance premiums and fewer change order surprises. Month 7-12, your institutional knowledge base strengthens: bid accuracy improves as estimators accumulate project history, and project managers develop deeper client relationships that improve AIA draw approval cycles. By month 12, a mid-sized firm (50-100 employees, $50M - $150M revenue) typically sees $300K - $600K in cumulative ROI from turnover reduction alone, with an additional $100K - $250K in margin improvements from tighter schedules and fewer safety incidents.
