Abstract

The construction of the Malo Bridge in Bojonegoro Regency encountered significant challenges during the superstructure erection phase, primarily due to limited site accessibility and the use of a less suitable erection method. This study aims to evaluate the comparative efficiency of two primary erection techniques: the use of a 250-ton crawler crane operated from land and a combined method involving a 100-ton crawler crane supported by modular pontoons operating from the water. A case study approach with a quantitative methodology was applied, focusing on three main parameters: erection duration, construction cost, and risk management. The analysis indicates that the land-based 250-ton crawler crane method required a shorter erection period of 181 days, compared to 203 days for the modular pontoon method, resulting in a time-efficiency gain of 10.84%. Furthermore, the 250-ton crawler crane method demonstrated greater cost-effectiveness and a lower level of operational risk. These findings highlight that selecting an erection method that aligns with the site’s geographical and logistical conditions is crucial for optimizing construction performance. Appropriate method selection can lead to significant improvements in both time and cost efficiency, especially in complex or constrained environments.

Abstract

Selecting the optimal deep foundation system is a critical task in major infrastructure projects, requiring a balance between structural performance, geotechnical constraints, and economic viability, as foundation costs typically represent a significant portion of the total budget. Bored piles and spun piles are two widely adopted deep foundation types, each offering distinct advantages in terms of capacity, installation speed, and environmental impact. Given the necessity for cost optimization in the Raw Water Supply Supplemental Project in Aceh Province, this study focuses on comparing the construction costs of these two foundation types for Aqueduct C. The foundation plan for Aqueduct C requires a total pile length of 2,870 meters with a diameter of 60 cm. The analysis uses unit cost data based on the Ministerial Regulation's Unit Price Analysis (AHSP) tables. The calculation results show that the total cost for the bored pile foundation is Rp2,847,074,353.90, while the total cost for the spun pile foundation is Rp3,205,844,730.90. This indicates that the bored pile foundation is more cost-effective for this specific project by approximately Rp358,770,377.00. The structural capacity analysis confirmed that the designed foundation group safely supports the axial load transferred by the piers.
