Abstract: With the increasing demand of urban lands for the developments, more and more construction projects are close to the other building or municipal engineering construction sites. This paper introduces a coordinated design scheme of two adjacentdeep excavations. Based on the safety and the schedule requirements of the both deep excavations, the proposed design fully considers the convenience of their construction and avoids the construction interference from the beginning. Therefore, this project is proved to be a successful one.

Key words: asynchronous, adjacentdeep excavations, different depths, coordinated design, comparison
