Spiral Ramp Construction Work for the International Parking Building Terminal 3 of Soekarno Hatta International Airport

Abstract

Soekarno-Hatta International Airport as the main gateway to Indonesia continues to develop infrastructure to support smooth operations and user comfort. One of the strategic projects currently being implemented is the construction of the Spiral Ramp at the Terminal 3 International Parking Building, which functions as a vertical circulation route for vehicles between floors. This activity aims to understand the construction process of the Spiral Ramp from technical and managerial aspects, as well as the implementation of work safety in the project area. The methods used include direct observation in the field, documentation of work progress, analysis of working drawings and spiral structures, and interviews with the project implementers. The results of the observation show that the construction of the Spiral Ramp uses a reinforced concrete structure with a gradual casting technique and special circular formwork. This project implements a strict quality control and time management system to meet the construction target. In terms of K3, all workers are required to comply with high work safety procedures considering the complex level of work risk. The conclusion of this activity shows that the construction of the Spiral Ramp at the Terminal 3 International Parking Building is carried out in a structured, innovative manner, and in accordance with construction safety standards.
