"In this episode we will learn how to inspect notching, cutting, and bored holes in solid lumber, learn how to determine whether alterations in floor joists, roof rafters, and stud walls are structural defects or are permitted by current standards, and learn about simple spans, thirds, knots, actual joist depths, cantilevers, entsion and compression. This is a must show for inspectors performing existing and new construction inspections." Paige Peters
