In an ingenious companion guide to his Architect's Portable Handbook, which gave "first-step rules of thumb for building design," Pat Guthrie helps you make certain such errors never happen. With Cross-Check, Guthrie offers a unique, easy-to-use matrix system that, when applied, ensures nothing is missing from your plans and every step is taken to assure coordination between drawings and project specs.
