This presentation provides an overview of construction methods and sequencing using 3D animations and images. It aims to help stakeholders understand projects and engage site teams. The presentation covers general site facilities, temporary works like sheet pile walls, dewatering, traffic management, and more. Construction methods for various elements like diaphragm walls, vibro compaction, piling, and more are presented. The sequencing of activities like bridge construction, reinforced concrete works, and steel erection are also demonstrated.
