At Slayden Constructors Inc., I review engineering drawings, geotechnical reports, and municipal and DOT specifications to define scope and identify site-specific risks. I prepare earthwork, utility, and paving takeoffs using AGTEK, Trimble Business Center, Civil 3D, and Bluebeam.

Previously, I prepared cost estimates and material takeoffs at SteelFab Inc., evaluating vendor and subcontractor quotes and coordinating pricing and scheduling information for field handoffs. I hold a B.S. in Civil Engineering from Oregon State University.
