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: 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, and on a schedule of our choosing, allows each subsequent division of work to be completed faster, more efficiently and without compromise.
