The work spans multiple building types rather than repeating a single scope — healthcare, data centers, K-12 and higher education campuses, and commercial and industrial facilities — across retrofit, major service repair, and design-build delivery, with in-house engineering, controls, and energy analysis. We are recruiting a Senior Mechanical Estimator in Fresno, California to own preconstruction estimating on large-scale commercial HVAC retrofits for a fast-growing, multi-state contractor.
