The presence of a number of medium to high-rise buildings alongside the excavation prompted the necessity of an induced risk management strategy. This strategy was based on a sequence of increasingly refined risk analyses and an explicit vulnerability assessment. The preliminary and standard analyses were largely based on empirical extrapolations and a moderate amount of site investigation. The detailed analysis stage involved a more comprehensive soil investigation, advanced numerical analyses and the execution of two instrumented trial sections.

My contention is that AI research should focus on interactive, autonomous systems, that is, agents. Emergent technologies demand so. We see how recent developments in (multi-) agent-oriented research have taken us closer to the original AI goal, namely, to build intelligent systems of general competence. Agents are not the panacea though. I point out several areas such as design description, implementation, reusability, and security that must be developed before agents are universally accepted as the AI of the future.
