REDDERSEN Architect ILLINOIS • MINNESOTA • WISCONSIN Structural Engineer ILLINOIS Plan Examiner DEPARTMENT OF BUILDINGS, CITY OF CHICAGO SINCE 1 9 14 Copyright 1939 by Edward E. Reddersen vk? FOREWORD No member of the Department of Buildings of the City of Chicago, and no member of any other department of the City of Chicago has had any hand, directly or indirectly, in the compilation of this Index Summary. No part of this Index, therefore, can be considered in any sense as any official wording or interpretation of the Building Code. Such wording or interpretation as contained in the Index is solely the responsibility of the author. His experience as Plan Examiner, Department of Buildings, City of Chicago, since 1914, has fitted him to know the needs of architects, engineers, and builders, and it is believed, to satisfy those needs with the first adequate index of any Chicago Build- ing Code. Since it is inevitable that errors and ambiguities should creep into this tremendously detailed work, the author will appreciate any notice of such errors or discrepancies. It should be noticed, however, that many apparent errors are due to conflicts in the code itself and not to the Index. This Index Summary does not include: — The Electrical Code The Fire Prevention Code Chapter 83 Water Supply and Distribution Systems Chapter 84 Steam Boilers and Unfired Pressure Vessels Chapter 85 Mechanical Refrigeration The Zoning Ordinance WAYLITE-SUPEROCK THE MODERN BUILDING MATERIAL WITH Light-Weight Concrete Aggregates INSULATING BACK-UP BLOCKS with Highest Fire Resistance Highest Insulation Value of any Lightweight Aggregate Highest Acoustical Value for Interior Exposed Walls Whitest Exposed Inside Wall 40% lower cost than Brick as a Back-up Material r ., Ideal for ^ ■ Easily .. ... r .

It should be referred to first if the class of use or type of building is not known, or if it is uncertain in what chapter the item under consideration properly belongs. Occupancy Chapters Index Summaries: These include complete detailed indexes of the individual chapters men- tioned below. Each is a specialized index for a particular class or group of related occupancies and should be used for design purposes. Such chapters can be used as a "check list" to insure that all Code requirements of a specialized character are complied with.
