Abstract

This paper describes remote and automatic monitoring systems for measuring vertical and horizontal displacements and tilt of structural elements. An automated total station and system of tiltmeters were employed at the excavation for the Ford Engineering Design Center. The 9.1-m-deep excavation was made through fill and soft clays and undercut the shallow foundations for a building 6 m from the edge of the excavation. The excavation support system consisted of a sheet pile wall supported by two levels of cross-lot and diagonal internal bracing. The two automated systems, the structural support system and construction details are described. Selected ground and structural responses collected by the automated systems are compared to those collected with conventional methods. The accuracies of the measured automated responses are discussed. The tilt meter data are shown to supplement the inclinometer data so that structural responses of an adjacent structure to the excavation can be evaluated.
