Do not cut, modify, or repair components. Report any damage before installation. The information in this book is offered as a minimum guideline only. Nothing contained in BCSI shall be construed in any manner as expanding the scope of responsibility of, or imposing any additional liabilities on the Truss Manufacturer.
Every project has different site conditions that can have a specific effect on the erection process. Before the first Truss is erected, every individual involved shall understand the plan for hoisting and Truss setting and the intended temporary restraint and Bracing requirements for a safe, efficient and accident-free bczi.
It is recommended that this review bb3 be followed before any Truss handling operations are performed. Proper restraint and Bracing of Trusses requires an understanding of triangulation in the various planes perpendicular to the planes of the members of the Trusses.
This understanding is essential for a safe installation. Purchasers and users of this guide are advised to visit the products section of sbcindustry. Use only the latest edition. Additionally, errata and updates are published periodically and are available at sbcindustry.
WARNING Bcai handling, storing, installing, restraining and Bracing of Trusses requires specialized training, clearly implemented bsci, and careful planning and communication among the Contractor, all installation crews and any crane operators.

Back Cover Considerations Before Starting This guide for builders features proper techniques for unloading, storing, lifting, erecting, installing, restraining and Bracing Trusses. Numerous graphics accompanied by written instructions provide an easy-to-follow reference. The methods and procedures in BCSI are intended to ensure that the overall construction techniques employed will put floor and roof Trusses in place safely.
Thus, SBCA, TPI and those who participated in the development of this guide expressly disclaim any responsibility for damages arising from the use, application, or reliance on the recommendations and information contained herein. Permanent Bracing must provide sufficient support at right angles to the plane of the Truss to hold every Truss member in the position assumed for it in the design.
The consistent message throughout all of these documents is that proper Truss handling, installing, restraining and Bracing are crucial for consistent jobsite safety and acceptable structural performance.
The sections of this book are available as B-Series Summary Sheets. Each Summary Sheet condenses the information contained in the corresponding section of this book into a few pages that emphasize the main points using a graphical representation of the text as fully as possible.
The goal is to provide clear, concise information for bfsi users so they can implement the handling, installing, restraining and Bracing bcwi contained herein more easily. During construction, Bcdi must not support any loads from equipment or construction materials until the Truss assembly is properly restrained and braced.
This document provides safe stack heights for several materials and illustrates good and bad loading practices. Trusses are engineered components that can be damaged through mishandling, jobsite modification or improper installation.
This Summary Sheet provides information on what to do if Trusses become damaged during the construction process. The following B-Series Summary Sheets were specifically created for special conditions that are encountered during bcis Truss installation and Bracing process: Floor Trusses are more stable during installation because they are built with the wideface of the lumber oriented horizontally.
Nevertheless, it is important to observe good installation, restraint and Bracing practices so floor systems are installed bsci and successfully, and offer better longterm floor performance. BCSI-B8 contains guidelines for using toe-nailed Connections and provides bcdi and lateral gcsi capacities for these Connections.

Connection options are also discussed for when toe-nailing is not enough. Multiple-ply Girder Trusses consist of two or more individual Trusses that must be attached together to act as a single member.
BCSI-B9 discusses various attachment methods and types of fasteners. Metal Plate Connected Wood Trusses are commonly used in post frame construction. The handling, storing, installing, restraining and diagonal bracing of n3 building compo- nents requires specialized training, clearly implemented procedures, and careful planning and communication among the contractor, crane operator and installation crew. Prior to component installation, the documents bb3 be bci and 3b to all appropriate personnel, in addition to proper training and a clear understanding v3 the installation plan, any applicable fall protection requirements, and the intended restraint and bracing requirements.
Trusses with clear spans of 60 feet or greater in length are very dangerous to install and may require complex temporary and bccsi bracing. Please consult a Registered Design Professional. Begin component installation only after any unsatisfactory conditions have been corrected. Do not cut, modify or repair components. Trusses are NOT designed to be fall protection anchors.
