Evaluating the quality of publicly available construction technology data in Indonesia

This study evaluated the quality of construction technology data across four categories—intrinsic, contextual, representation, and accessibility—and examined how these factors influence potential data use. The research adopted a qualitative approach, systematically identifying and assessing publicly available data sources on construction technology from government, academia, industry, and society. Government sources include research databases, technical reports, and patents; academic sources comprise Scopus and the local repository Science and Technology Index; and industry sources encompass annual reports and social media. The evaluation revealed that government data demonstrate the highest credibility and the most complete metadata, but were updated infrequently. Despite limited metadata, industry data remain reliable due to consistent annual publication schedules. Academic data show moderate quality, offering substantial datasets but with irregular update frequencies. Most data sources are available in English or Indonesian and are predominantly open access, except for subscription-based academic journals. In summary, the vast majority of construction technology data sources in Indonesia are either unstructured with limited information or semi-structured large databases from credible institutions with unpredictable or irregular updates, presenting challenges for technology landscape mapping. Government and Scopus databases show significant potential but require greater standardisation and, in the case of Scopus, advanced natural language processing-based extraction methods to maximise their utility for construction technology landscape development.
