Drywall cracking and crowning (i.e., ridging) occurs mainly in dry regions of the country that occasionally experience periods of high humidity. This document explains the mechanism by which DCC occurs, how seasonal lumber movement is not the culprit, and how correct gypsum board installation practices avoid the problem. This document is part of the SBCA Research Report series.
Concern about mold contamination has gained extensive media coverage and awareness has mounted among builders, homeowners and insurance companies. This four-page document addresses the topic presenting facts, recommended reading and a reference list on the subject. This document is part of the SBCA Research Report series.
Manufactured Gable End Frames used in the end walls of buildings with gable style roofs often require special bracing, especially in high-wind areas. This document discusses the importance of permanent bracing and/or reinforcement for the Gable End Frame and reviews some basic design considerations for this bracing.
This document contains the latest language from Chapter 2 of ANSI/TPI 1-2014 National Design Standard for Metal Plate Connected Wood Truss Construction. ANSI/TPI 1 is the industry’s consensus standard and is referenced by the IBC and IRC. This design responsibilities document is intended as a comprehensive and thorough approach to the clarification of design responsibilities when metal plate connected wood trusses are incorporated into a building or structure.
This guide for builders features proper techniques for unloading, storing, lifting, erecting, installing, restraining and bracing wall panels. It includes specific information for protecting wall panels from weather and damage at the jobsite, how to lift bundles and individual wall panels by crane, restraining/bracing guidelines to prevent wall panels from toppling during erection, installation tolerances to keep the wall panels in plane and plumb and basic construction loading and materials placement recommendations.
Learn the requirements of proper crane use and truss handling. Covering responsibilities and key considerations, this document discusses topics including crane size, hoisting, crane set up and inspection. This document is part of the SBCA Research Report series.
This two page document provides important safety information to builders who are using mechanical means (such as cranes or lifts) to handle and hoist wood wall panels to which synthetic hoisting straps have been attached by the wall panel manufacturer. The document provides important inspection and hoisting guidelines for lifting with these straps and is intended as a supplement to the information found in the SBCA document WallPanel11x17-P, Guide for Handling, Installing & Temporary Bracing of Wall Panels.
This four-page document contains essential information for wall panel customers. There is a comparison of time and material savings provided by wall panels over stick framing from the Framing the American Dream project. A checklist is also included that reviews important information typically required to ensure that wall panels are manufactured to the correct specifications.
This four-page document presents a generic truss design drawing with color-coded explanations for every item of information contained therein. Truss design drawings have long been a source of confusion for contractors, design professionals and building inspectors alike. Use this valuable tool to educate your market and increase understanding of the important information presented on truss design drawings. The final page lists tips for crews to follow in order to avoid installation errors.
Formerly TTBPlan-D - How to Read a Truss Placement Plan. This two-page document discusses the information contained on Truss Placement Diagrams. It explicitly answers the following questions: What are Placement Diagrams, Are Placement Diagrams Engineering Documents, Should a Placement Diagram be sealed with an Engineer's seal, & Why does the Truss Industry supply Placement Diagrams? A great educational tool that textually and visually addresses this important topic.
