Abstract

AbstractFor a successful execution of construction projects, project owners and contractors need for a good management system capable of monitoring and evaluating progress of the project. By employing a descriptive quantitative method, this study aimed to explore project management components used by contractors in the city of Kudus, Central Java Indonesia and to find out its relation to successful completion of their projects and determine the most dominant component in the management. Data for the study were in the form of numbers collected from 100 respondents through survey. Finding of the study were then quantitatively analyzed based on our pre-determined criteria. Our findings showed successful completion of projects was very much determined by the quality of project management, including planning, organizing, actuating and controlling. Among those four components of management, organization was the most dominant aspect to influence successful execution of a project. Role of organization in the project was critical to coordinate parties by which they were enabled to supervise, optimize specialization, efficiently use the budget and build harmonious relationship among parties.Keyword: Management, Contractor, Work Quality

Abstract

This study investigates the influence of bored pile group size and pile depth on the settlement of building foundations constructed on soft soil in the Pakunden area, Semarang City. The analysis considered bored piles with a diameter of 0.8 m, spacing of 2.4 m, group configurations of 2 × 2, 3 × 3, and 4 × 4 piles, and depths of 10 m, 16 m, and 24 m. Elastic settlement was evaluated using the Vesic analytical method, while consolidation and total settlement were analyzed numerically using PLAXIS 2D V22 with the Hardening Soil Model. The results indicate a nonlinear relationship between pile number, pile depth, and settlement. The smallest numerical settlement was 0.04107 m for the 3 × 3 group at 10 m depth, whereas the largest was 0.17625 m for the 4 × 4 group at 24 m depth. Increasing pile number or depth did not consistently reduce settlement. Foundation performance was controlled by soil stratification, load distribution, pile-group interaction, and the extent of compressible soil mobilized under loading. These findings support integrated analytical and numerical evaluation for design.
