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.
