NON-DESTRUCTIVE TECHNIQUES AS A FORENSIC APPROACH FOR CIVIL ENGINEERING STRUCTURES: A CASE STUDY OF THE UNIVERSITY OF NAIROBI FOOTBRIDGE.

Abstract
This paper examines the utilization of Non-Destructive Techniques on civil engineering structures. The
structure chosen for this study is the University of Nairobi footbridge. This report also reviews the
current studies and development in this field of study. The review also includes a brief discussion on
destructive techniques for comparative purposes. The focus of the study is however on the use of Schmidt
hammer and Profometer.
The Schmidt rebound hammer is basically a service tester with an apparent theoretical relationship
between the strength of the concrete and the number of rebounds of the hammer. It is used worldwide to
estimate the strength of concrete due its speed and convenience in execution, simplicity, portability and
relatively low cost. Similarly, the Profometer is also widely used. Its purpose is the measuring of concrete
cover depth and reinforcement bar diameter.
Through carrying out a comparison between data obtained from the test and the actual design drawings
of the structure, this project hopes to bring more attention to non-destructive testing as a sufficient
means of providing accurate data for inspecting civil engineering structures.
