Hatmoko p-ISSN 2580-7552. e-ISSN 2548-7515. Volume 10. Number 1, pp 47 Ae 62, 2025 INTRODUCTION In heritage building rehabilitation projects, knowledge is not solely derived from technical documents or conservation guidelines. Rather, it relies heavily on the practical experience of workers, professional intuition, and an understanding of historical context and traditional construction techniques . This knowledge is often tacit because it is acquired through direct involvement in restoration activities, the selection of traditional materials, and the interpretation of building conditions that are not explicitly outlined in standard drawings or technical specifications . The success of these projects largely depends on the ability of skilled workers and experts to adapt technical approaches to the unique characteristics of each heritage However, the documentation of such experiential knowledge remains highly limited . Consequently, valuable lessons learned from these projects often remain undocumented and cannot be effectively transferred to future projects. In the construction industry, knowledge is acquired not only from formal documents and technical guidelines but also from workersAo experience, professional intuition, and field practices that are not always systematically documented . This type of knowledge is generally tacit and embedded within individuals. It is difficult to transfer without direct interaction or shared experience . In construction projects, tacit knowledge is a valuable asset for construction companies . , yet it is vulnerable to loss if not properly managed . These conditions disrupt the organizational learning cycle . , leading to the potential loss of critical knowledge when projects are completed or key personnel are relocated. Heritage buildings are more than just physical representations of the past. They also embody social and architectural values that must be preserved sustainably . However, conserving and rehabilitating these buildings presents significant technical and managerial challenges, particularly because these processes must integrate preservation principles with modern construction approaches. The knowledge required for heritage building rehabilitation projects is generally tacit and is acquired through direct experience, field observation, and interaction among workers across generations. This knowledge is difficult to transfer through formal documents or technical guidelines . In Indonesia, most knowledge transfer processes are still informal, relying on social networks and daily work practices . Consequently, valuable knowledge is often lost when a project is completed or workers transfer to other assignments. Previous studies have extensively discussed the importance of knowledge management systems in the construction sector . However, literature that specifically examines knowledge transfer in heritage building rehabilitation projects, particularly in developing Doi: https://doi. org/10. 251005/livas. The strategy of knowledge transfer in the rehabilitation project of Immanuel Church (Bledu. Semarang City Febrianty. Wibowo. Hatmoko p-ISSN 2580-7552. e-ISSN 2548-7515. Volume 10. Number 1, pp 47 Ae 62, 2025 countries, remains limited. Most research has focused more on technical aspects of conservation or material preservation, while the social dimensions, organizational culture, and strategies for knowledge sharing among project stakeholders have been relatively underexplored (Della Torre et al. , 2. This limitation indicates that the existing body of literature has not fully captured the novelty and complexity of collective learning processes. Based on this background, the research problem addressed in this study is: How are the knowledge transfer strategies implemented in the rehabilitation project of Immanuel Church (Bledu. in Semarang City? This study aims to identify and describe the knowledge transfer strategies used in heritage rehabilitation projects. The study also aims to provide strategic recommendations for developing effective knowledge management systems. The research is significant because it contributes to the advancement of knowledge management theory in the context of rehabilitation projects. Furthermore, construction companies, local governments, and heritage preservation agencies can use the studyAos findings to design training programs, documentation practices, and collaborative systems that support the sustainable preservation of conservation knowledge. This study uses a qualitative approach with an exploratory case study strategy. Data were collected through in-depth interviews with construction professionals experienced in rehabilitation projects, as well as through field observations and analysis of project documents. The data were analyzed thematically to identify patterns, themes, and knowledge transfer strategies that emerged from actual field practices. It is also assumed that project-specific strategies such as experience-based mentorship, cross-cultural training, technology-based documentation, and open evaluation can strengthen the knowledge transfer process in rehabilitation projects. Therefore, this study posits that even though formal systems have not yet been fully developed, adaptive and project-based knowledge transfer practices can be optimized to improve knowledge sustainability. Although the issue of knowledge transfer has received considerable attention in construction management studies, most existing research remains focused on developing information technology and knowledge database systems, as well as quantitative approaches. There is limited emphasis on actually implementing knowledge transfer in heritage building rehabilitation projects. Furthermore, literature on rehabilitation projects in developing countries such as Indonesia tends to describe technical aspects or preservation policies but rarely explores how tacit knowledge is transferred on-site. This studyAos qualitative approach is novel because it identifies and analyzes knowledge transfer strategies based on direct experiential practices. This study is important because it addresses the existing gap by employing a qualitative approach that Doi: https://doi. org/10. 251005/livas.

Recognizing experience-based solutions contributed by workers is crucial for fostering interpersonal trust . This approach makes knowledge transfer to become more dynamic and widely distributed, enhancing competitiveness. Integrating experience and technology into the knowledge transfer process is a fundamental strategy for building adaptive, innovative, and highly competitive project-based organizations . Workers' experience should not remain confined to the field. Instead, it must be transformed into explicit knowledge that can be stored, accessed, and reused. Using technology to enhance transparency is a key strategy. Information systems are recognized as drivers of transparency . With appropriate information systems, processes, decisions, and knowledge are no longer the exclusive domain of specific individuals, but rather, can be accessed, reviewed, and learned by all relevant stakeholders. An approach combining experience-based mentoring with modern expertise is essential. Mentoring fosters adaptive learning and strengthens working relationships . Transparent evaluation ensures that every solution to risks and occupational safety issues is acknowledged and addressed. Experience-based learning accelerates adaptation to project challenges . Transparent safety evaluations are not only a moral and legal obligation, but also a crucial strategy for building sustainable, risk-adaptive project organizations. Conducting joint training involving the entire workforce, including cross-cultural training to align different working approaches, is essential . Amid the complexity of the project environment and the diversity of teams, training is essential for harmonizing work approaches 3 Having High Complexity and Limited Project Duration Construction projects are characterized by their complexity and limited duration . effective knowledge transfer strategy is illustrated in Fig. Fig. 4 Knowledge transfer strategy for the third phenomenon Doi: https://doi. org/10. 251005/livas.

Number 1, pp 47 Ae 62, 2025 Fig. Knowledge transfer strategy for the sixth phenomenon The knowledge transfer process requires visual guidelines to explain preservation rules and standards. Effective knowledge transfer strategies involve developing visual guides for these regulations because visual media has been proven to support experience-based learning and significantly enhance technical understanding . Integrating instructional videos that provide detailed explanations is also important because video media effectively facilitates the transfer of tacit knowledge . Using long-term storage and access media emphasizes the role of knowledge management systems (KMS) in ensuring the retention of durable information and broad accessibility . Offline databases developed for locations without internet connectivity demonstrate that flexible digital media can support knowledge transfer in challenging work environments . Continuous evaluation and improvement processes are crucial because they contribute to organizational learning and effective knowledge transfer . Collecting feedback to improve visual guidelines demonstrates that active workforce participation enhances learning effectiveness . The findings of this study significantly advance knowledge in the field of knowledge management, particularly in heritage building rehabilitation projects in developing countries. Using a qualitative approach, this study reveals that knowledge transfer strategies in heritage rehabilitation projects do not rely solely on formal systems. Rather, they emerge contextually through social practices rooted in experience, trust, and cross-generational collaboration. These findings expand the theoretical framework of knowledge management, which has traditionally been developed for highly technocratic, fully digitized industrial sectors. The study also emphasizes the importance of informal elements, such as mentorship, non-hierarchical communication, and reflective evaluation, as key mechanisms for preserving conservation knowledge that cannot be captured by conventional technical documentation systems. Thus, this study provides a theoretical contribution to knowledge management literature Doi: https://doi. org/10. 251005/livas.
