scope:

This guide presents a system for making a condition survey of concrete in service. A condition survey is an examination of concrete for the purpose of identifying and defining areas of distress. The system is designed to be used in recording the history of a project from inception through construction and subsequent life of the structure.

While it probably will be used most often in connection with the survey of concrete that is showing some degree of distress, its application is recommended for all concrete structures. In any case, records of the materials and construction practices used should be maintained because they are difficult to obtain at a later date.

The committee has attempted to include pertinent items that might have a bearing on the performance of the concrete. Those making the survey should, however, not limit their investigation to the items listed, thereby possibly overlooking other contributing factors. Following the guide does not eliminate the need for intelligent observations and the use of sound judgement.

Those performing the survey should be experienced and competent in this field. In addition to verbal descriptions, numerical data obtained by laboratory tests and field tests and measurements should be obtained wherever possible. Photographs, including a scale to indicate dimensions, are of great value in showing the condition of concrete.

The check list is provided to facilitate a thorough survey. The definition of terms and associated photographs are an attempt to standardize the reporting of the condition of the concrete in a structure.

This guide should be used in conjunction with the following:

1. ACI Committee 116 "Cement and Concrete Terminology" (ACI 116R).

2. ACI Committee 311 "Recommended Practice for Concrete Inspection" (ACI 311.1R).

3. ACI Committee 201, "Guide to Durable Concrete" (ACI 201.2R).
