Safety Assurance for Challenging Geotechnical Civil Engineering Constructions in Urban Areas ()
ABSTRACT
Safety is the most important aspect during design,
construction and service time of any structure, especially for challenging
projects like high-rise buildings and tunnels in urban areas. A high level
design considering the soil-structure- interaction, based on a qualified soil
investigation is required for a safe and optimised design. Due to the
complexity of geotechnical constructions the safety assurance guaranteed by the
4-eye-principle is essential. The 4-eye-principle consists of an independent
peer review by publicly certified experts combined with the observational
method. The paper presents the fundamental aspects of safety assurance by the
4-eye-principle. The application is explained on several examples, as deep
excavations, complex foundation systems for high-rise buildings and tunnel
constructions in urban areas. The experiences made in the planning, design and
construction phases are explained and for new inner urban projects
recommendations are given.
