Being a regional CM/GC with annual revenues over $400 million, and with 95% of our work program being acquired through relationships---we rely heavily on our construction partners, subcontractors and others to deliver on our commitments. From subcontractor selection, through preconstruction and the construction process, Greiner Electric has always supported our clients and our efforts to deliver on our promises.
