ABSTRACT
The construction requirements of the deep foundations for the Urban Infrastructure and Hydro power projects in terms of the equipment, manpower and other resources planning are similar in nature. However, the construction and sequencing are the challenging issues for each activity. The paper tries to bring all the construction challenges in executing the deep foundations starting from the equipment planning, logistics, execution, geographical constrains, work front availability and uncertainties in the geological conditions. Maneuvering of the key construction equipment’s like the trench cutters, hydraulic piling rigs and cranes movement in the metros is limited by the working space while on the contrary its limited spaces within the mountains. In terms of the geological constrains metros have the utility diversions and underground debris to be cleared before start of the works, while the fresh and completely weathered rock with shear zones and cavities pose challenges during the construction. In this paper, authors tries to bring in case studies of the projects executed in metros and hydro power project with the same equipment highlighting the insights for better planning and scheduling of the activities.
