It includes a checklist of the many details that maybe considered in making a report and descriptions for various concreteconditions associated with the durability of concrete. A visual inspection is an examination of concrete toidentify and define many of the various conditions concretemay exhibit during its service life. The visual inspection istypically limited to the surfaces of the concrete structure thatare visually accessible.
The inspection results also aid in earlydetection of distress and deterioration, enabling repair orrehabilitation before replacement is necessary. It is important that the inspector properly document anyobservations related to environmental and loading conditions. Inspections are often supplemented with nondestructivetests, destructive tests, and other investigations, especiallywhen distress and deterioration is observed and informationregarding the internal condition of the concrete is needed.
While a visual inspection is most often used in 2011 the condition survey of concrete that is showing defectsor some degree of distress, its application is recommendedfor all concrete structures. It is important that the inspectorproperly document any observations related to environmentalexposure effects from physical loads, deformations, defects,imperfections, and distressdurability, and performance. Concrete material records and construction practices shouldbe collected and reviewed.
The checklist includes items that might have a bearing onthe durability and performance of the concrete. Individualsmaking the survey should not limit their investigation to theitems listed, but should review any other contributingfactors. Following the guide does not eliminate the need forintelligent observations and the use of sound judgment. Individuals performing the inspection should be experiencedand competent in concrete condition surveys.
In addition towritten descriptions, sketches of relevant features are valuableand encouraged. Video coverage should ack considered for docu-mentation as it provides an enhanced visual dimension thatmay exceed that of still photography. The descriptions and photographs provided in Chapter 2illustrate typical observations encountered during inspectionsand aid 20.11 the preparation of a condition survey report byidentifying the characteristics of potential problems anddescribing their condition.
Thoseperforming the survey should be thoroughly familiar withthe terminology of various types of imperfections anddistresses.
