Special Inspection

The following Quality Assurance Guideline was prepared by SEAO for use on Project Drawings for compliance with the 2006 IBC as amended by the State of Oregon. The notes will proceed the tables on a typical set of drawings. The guidelines will Need to be customized for each project, both notes and tables. Cell areas, on the tables, with 'a' or 'b' are to be filled in. Delete items/tables not needed for a specific project. This document is not intended to be boiler plate. Supplement this documents with division one of the specifications as needed.

For use with the 2003 IBC click here for Version 1 of the guidelines.

Seminar Videos and Notes

SEAO has several past seminars professionally recorded on VHS videotape for purchase. Each seminar is recorded in its entirety and fills four or five VHS tapes. Copies of the original seminar proceedings and notes are included. SEAO has recommended 4 PDH’s for viewing all portions of a seminar tape set and reading the accompanying seminar proceedings. Each seminar is available for $150. Please Contact Jane Phifer to purchase.

Precast Cladding: Architectural Uses, Structural Analysis, and Design Considerations
Structural Rehabilitation of Existing Buildings, Spring 2000, This seminar is intended to familiarize engineers, architects, contractors, and building owners and managers with the design & analysis, materials testing, construction, rehabilitation, and code considerations associated with existing structures. The design, analysis, and renovation of existing structures present many challenges for all members of the design team. Specialized knowledge on the part of the architects, engineers, and contractors associated with the project are essential for an effective design team. Renovation/rehabilitation projects present the design team with the challenge of blending their work with the existing structure while creating their own mark of excellence. Often times these projects involve buildings of historical significance that come with additional guidelines and challenges.
Design, Analysis, and Rehabilitation of Parking Structures, Winter 1999, This seminar is intended to familiarize engineers, architects, contractors and building owners and managers with the design, analysis, construction, rehabilitation, and code considerations associated with parking structures. Several case study examples will be included. The design, analysis and construction of parking structures present many challenges for all members of the design team. A parking structure’s unique occupancy requires specialized knowledge on the part of the architects, engineers and contractors associated with the project. Architectural issues include traffic flow and stall geometry considerations. Structural engineers should be aware of special design and serviceability constraints. All members of the design team can learn valuable lessons in controlling project costs and schedule from practical construction case studies.

ATC-20 Manuals

In July of 2001, SEAO presented a training seminar for ATC-20 inspectors. We have an overstock of manuals that we are now selling. ATC-20 and ATC-20-2 come as a set and we are selling them it $32.00 ($39.00 + shipping from ATC) and ATC-20-1 is $12.00 ($18.00 + shipping from ATC). Please Contact Jane Phifer. We have many copies of the manuals, but a very limited number of the field guides. The abstracts below describe the three manuals.

ATC-20 ABSTRACT: Introduced two weeks prior to the 1989 Loma Prieta earthquake, the ATC-20 report provides procedures and guidelines for making on-the-spot evaluations and decisions regarding continued use and occupancy of earthquake damaged buildings. Written specifically for volunteer structural engineers and building inspectors, the report has become the de-facto national standard for safety evaluation of earthquake-damaged buildings. The report includes rapid and detailed evaluation procedures for inspecting buildings and posting them as INSPECTED (apparently safe, green placard), LIMITED ENTRY (yellow placard) or UNSAFE (red placard). Also included are special procedures for evaluation of essential buildings (e.g., hospitals), evaluation procedures for nonstructural elements and geotechnical hazards, and guidance on human behavior following earthquakes.
ATC-20-2 ABSTRACT: The report provides updated assessment forms, placards, and procedures that are based on an in-depth review and evaluation of the widespread application of the ATC-20 procedures following five earthquakes occurring since the initial release of the ATC-20 report in 1989. One of the principal recommendations is the replacement of the yellow LIMITED ENTRY posting placard with a revised yellow placard entitled, RESTRICTED USE. Also included are procedures for conducting initial wind-shield surveys of damaged areas, guidance on estimating the cost to repair earthquake damage, and updated guidance on human behavior following natural disasters, including a concise handout for owners and occupants of damaged buildings.
ATC 20-1 ABSTRACT: The ATC-20-1 report, Field Manual: Postearthquake Safety Evaluation of Buildings, was introduced in 1989 as a companion document to the ATC-20 report. The pocket-sized field manual summarizes the postearthquake safety evaluation procedures in brief concise format designed for ease of use in the field. This report set consists of two documents, the ATC-20 Report, Procedures for Postearthquake Safety Evaluation of Buildings, and the ATC-20-2 Report, Addendum to the ATC-20 Postearthquake Building Safety Evaluation Procedures. The ATC-20 Report was developed under a contract from the California Office of Emergency Services (OES), California Office of Statewide Health Planning and Development (OSHPD) and FEMA. (Published 1989, 152 pages). The ATC-20-2 Addendum, developed under a grant from the National Science Foundation (NSF), with funding provided by the U. S. Geological Survey (USGS), contains revised placards and safety assessment forms, based on ATC-20 use following the 1989 Loma Prieta, 1992 Cape Mendocino, 1992 Landers, 1992 Big Bear, and 1994 Northridge earthquakes.

Oregon Snow Load Manual - Snow Load Analysis for Oregon

Published by SEAO in 1971 (revised in 2008) and as referenced in the appendix of Chapter 16 of the Oregon Structural Specialty Code, the Snow Load Analysis for Oregon provides the ground snow load to be used in the determination of design loads for buildings and other structures in Oregon. This supplement to the code has charts for all counties in the state with ground snow loads based upon elevation. This documant is now outdated. Please see order form here for new document.
