The scope encompasses site demolition, excavation, utilities coordination with the Oregon Utility Notification Center (48 business-day advance notice required), electrical service installation, concrete and paving work, and construction of a new 349-square-foot office occupancy Type V-B building with walls, windows, doors, siding, roofing, electrical and mechanical systems, interior finishes, and reconnection of existing site equipment including the truck scale.

A hazardous building materials survey found no asbestos-containing materials within inspected scope but notes suspect ACMs may be present in inaccessible spaces.
