Abstract
The Doha high-rise tower consists of a 4 level basement which required an excavation depth of 16m along the site perimeter. Minimization of impact of excavation-induced ground movements on the adjacent structures and underground utilities was one of the major considerations in the design and construction of the excavation and its temporary retaining system. The temporary retaining system initially consisted of anchored secant pile walls with toe grouting along the entire site perimeter. After excessive movement was detected on one section of the southern wall, inclined steel bracing was installed inside the excavation as a remedial measure to provide additional lateral support to the wall. This paper discusses the geotechnical aspects of the design and construction of the excavation and its retaining system, the analysis approaches employed to evaluate the conditions of the moving wall, and the remedial measures taken to prevent further wall movement.

A Case History of Deep Excavation in Doha
Chicago, Illinois
The Doha high-rise tower consists of a 4 level basement which required an excavation depth of 16m along the site perimeter. Minimization of impact of excavation-induced ground movements on the adjacent structures and underground utilities was one of the major considerations in the design and construction of the excavation and its temporary retaining system. The temporary retaining system initially consisted of anchored secant pile walls with toe grouting along the entire site perimeter. After excessive movement was detected on one section of the southern wall, inclined steel bracing was installed inside the excavation as a remedial measure to provide additional lateral support to the wall. This paper discusses the geotechnical aspects of the design and construction of the excavation and its retaining system, the analysis approaches employed to evaluate the conditions of the moving wall, and the remedial measures taken to prevent further wall movement.
