The production of any PMHI Building Package begins with a computer analysis of the project before any materials are cut. The computer actually designs the roof trusses required for the most efficient roof system. These designs are then reviewed and approved by our engineers and a copy of each roof truss calculation is provided for your building department approval. The truss webs and chords are cut on our computer controlled Alpine Linear Saw. Not only are all cuts precisely made, the computer optimizes the use of the materials for minimum waste, too.
