Abstract

Amid increasingly fierce competition in the construction industry due to the growing number of service providers and limited market share, achieving optimal cost performance, timely delivery, quality compliance, and zero workplace fatalities has become more challenging. To monitor project performance effectively, companies must establish Key Performance Indicators (KPIs) as benchmarks for project evaluation. One internal factor within PT. PP Persero Tbk is the centralized e-procurement system, which plays a crucial role, especially in EPC (Engineering, Procurement, and Construction) projects. Data from 2020–2022 indicates delays across centralized e-procurement processes in all projects, with procurement delayed in 7 out of 10 required steps: technical clarification, price negotiation, required negotiation evaluation documents, negotiation evaluation, objection period, contract draft review, and final contract wet signatures leading up to contract release. This highlights a suboptimal e-procurement progress performance. This study involved a survey comprising 61 variables related to the potential impact of e-procurement on progress performance, distributed among internal and external stakeholders. Validity and reliability tests were conducted prior to analysis using principal component analysis (PCA). A total of 43 respondents completed the survey. The results of the validity and reliability tests confirmed that all 61 variables were valid and reliable. PCA results identified 16 principal components, with 25 variables exhibiting positive loadings in Component 1, 18 variables in Component 2, and the remaining variables distributed across Components 3–6. The study indicates that focusing on Components 1–6 can serve as a priority framework for addressing variables to significantly improve e-procurement progress performance.

Abstract

LRT Jabodebek as the first LRT infrastructure project in Indonesia has provided lessons on the implementation of dynamic capabilities on manufacturing aspects for the construction industry. In order to meet the requirements 2900 units of U-Shape Girder, production under normal conditions is expected to be completed by 2020. The acceleration of completion led to a significant increase in project requirements, accelerated completion of construction led to production shortages. Meeting the need for acceleration requires factories to be able to increase their production capacity by using steam curing methods. This case study uses a qualitative approach and focuses on dynamic capabilities in the production process. As a role model of application of manufacturing dynamic capability, the project has demonstrated the role of technology in increasing productivity. The integration of methods, asset positioning, and management processes are the most dominant productivity factors in accelerating the production of U-Shape precast girder. Optimum production performance can be achieved by integrating factory roles, project sites and management supported by adequate resources and staff experience
