SELF-PERFORMING ABILITY > McAlvain is one of the largest self-performing contractors in the Pacific Northwest.  We routinely self perform over 30% of the work on our projects including construction activities such as site work including earthwork and utilities, foundations, structural and architectural concrete and architectural finishes. The ability to successfully complete critical early stages of our projects with great accuracy, on a schedule of our choosing, allows each subsequent division of work to be completed faster, more efficiently and without compromise.
