This report describes aspects of recent braced excavation constructed in built up areas where adjacent buildings or underground utilities are likely to be subjected to settlement and damages. Trends and choice of earth retaining structures for deep excavation are present, and some desigen and construction techniques are introduced in order to minimise possible adverse effects to the urban environment.
