    Challenges of Virtual Design and Construction Implementation in Public Projects
    (Pontificia Universidad Católica del Perú. Facultad de Arte y Diseño, 2021) Prado Lujan, Guillermo; Pontificia Universidad Católica del Perú
    The Peruvian AEC industry has started implementing VDC and BIM in public projects due to recent regulations that state the progressive adoption of BIM (as a methodology) in public construction. Regardless of the benefits of these new approaches, some challenges to VDC implementation have emerged as a response to the resistance to change of the Peruvian AEC industry, which is stronger in the Peruvian public sector. The aim of this paper is to present the challenges found in the author´s VDC implementation experience in a public project, as part of the third VDC Certificate Program in Lima lead by CIFE from Stanford University. These challenges will be identified based on a schema, constructed by the literature review. The results show that the main challenges found are the lack of commitment and the lack of collaboration between stakeholders. These results suggest the need to overcome this resistant-to-change environment by focusing on training programs and conducting capability assessments within public institutions before start implementing VDC, so more benefits will be achieved by the Peruvian public institutions.

    A Scenario-Based Model for the Study of Collaboration in Construction
    (Pontificia Universidad Católica del Perú. Facultad de Arte y Diseño, 2021) Garcia, Alejandro; Murguia, Danny; Pontificia Universidad Católica del Perú
    The construction sector has been widely criticized for its low productivity, fragmented structure, and adversarial relationships. To address these problems, some industry actors are adopting innovations such as lean construction, digital technologies, and collaborative contracts. However, these transformative innovations are underpinned by inter organizational collaboration within complex supply chain networks. Understanding collaboration in theory and practice is a difficult task. Therefore, this study aims to investigate factors influencing collaboration and develop a model for inter-organizational collaboration. To achieve this aim, first, a literature review on collaboration in construction was conducted. Second, qualitative data were collected via semi-structured interviews using the critical incident technique. Third, data were deductively and inductively analyzed using thematic nodes. Data showed that collaboration can be classified into four dimensions: trust, project uncertainty management, client’s operational capability, and business relationships. Finally, an empirical framework was constructed using the scenario technique. Client attributes and Supply Chain Capabilities were found to be the most influential and uncertain factors. Based on these, four collaboration scenarios were developed and assessed with illustrative implications derived from the empirical data. The scenario-based model would provide a further understanding of inter-organizational collaboration within supply chains and would aid Lean Construction practitioners to develop collaborative relationships.
