The purpose of this paper is to clarify that while integrated project delivery (IPD) methods can be momenta for restructuring architectural practice, they do not predetermine specific patterns of restructuration for the roles, responsibilities and services of architects.

This paper is based on a multiple case study design; two IPD projects were theoretically sampled and studied. The data collection methods included semi-structured interviews and observations. An inductive data analysis approach was applied to frame the phenomena, conduct cross-case comparisons and develop propositions.

While IPD implementations set expectations for new structures for practices, it is the project participants’ situated decisions that lead to the restructuration of some dimensions of architectural practice. The dimensions in this study included team formation, design leadership and collaboration and architectural services. IPD project participants locally changed and redefined conventional roles, responsibilities and project artifacts (e.g. drawings and models) that concerned design development and coordination.

IPD context, by itself, does not predetermine a fixed pattern of change in establishing designers’ roles, responsibilities and services because restructuration is highly negotiated amongst the IPD parties and can lead to different responses to this contractual setting. Contracts set expectations for collaborative behavior, but the fulfillment of these expectations is situated and emerging as project participants negotiate to develop practices.

While IPD research and guidelines aim to provide recipes for IPD implementation, this study contributes to the body of knowledge by clarifying that IPD is a context in which unprecedented ways of practice restructuration could emerge.

Through the study of visualizations, virtual worlds and information exchange, the purpose of this paper is to reveal the complex connections between technology and the work of design and construction. The authors apply the sociotechnical view of technology and the ramifications this view has on successful use of technology in design and construction.

This is a discussion paper reviewing over a decade of research that connects three streams of research on architecture, engineering and construction (AEC) teams as these teams grappled with adapting work practices to new technologies and the opportunities these technologies promised.

From studies of design and construction practices with building information modeling and energy modeling, the authors show that given the constructed nature of models and the loose coupling of project teams, these team organizational practices need to mirror the modeling requirements. Second, looking at distributed teams, whose interaction is mediated by technology, the authors argue that virtual world visualizations enhance discovery, while distributed AEC teams also need more traditional forms of 2D abstraction, sketching and gestures to support integrated design dialogue. Finally, in information exchange research, the authors found that models and data have their own logic and structure and, as such, require creativity and ingenuity to exchange data across systems. Taken together, these streams of research suggest that process innovation is brought about by people developing new practices.

In this paper, the authors argue that technology alone does not change practice. People who modify practices with and through technology create process innovation.

The purpose of this paper is to inquire into the reasons why Construction Operation Building Information Exchange (COBie) has not become mainstream across the construction industry despite the significant attempts to promote it.

This paper framed and compared the normative model of COBie to a descriptive model of COBie. The normative model was based on the assumptions and planned procedures outlined in the COBie documentation. The descriptive model was developed through a case study of COBie implementation, with ethnographic observations, interviews and artifact analysis as the data collection methods and thematic analysis as the data analysis method.

The comparative analysis of the normative and descriptive models showed that the underlying normative assumptions of COBie can be challenged in its implementation. In the case study, implementing COBie disrupted the conventional practice of few participating firms as the data requirements and the expected sequences and timelines of tasks were not aligned with the industry norms for exchanging data. Furthermore, the normative model of COBie could not account for the unanticipated variability in the internal routines of firms for submittal production.

COBie, as an instruction-based model, may not provide enough flexibility for some firms to adapt to its requirements such that COBie tasks become integrated with their existing workflows. COBie tasks may become additional efforts, and at times, conflict with the industry norms and firms’ routines, and therefore, disrupt the efficiency goals.

This paper provides empirical evidence to clarify why implementing COBie has not been as efficient for all industry players as expected.

This paper discusses the communicative process of messy talk that enables collaborative problem-solving and tacit knowledge sharing among interdisciplinary team members. The paper aims to (1) trace relevant literature and lay out the conceptual and operational definitions of messy talk, (2) highlight messy talk as an enacted communication competence and (3) discuss the antecedents of messy talk and offer empirical propositions to guide future research.

This conceptual paper traces and integrates relevant literature from the construction, management and organizational and group communication disciplines to promote and foster research on messy talk.

Based on extant research on messy talk, the paper first provides clear conceptual and operational definitions of the messy talk construct. Second, using practice perspective, messy talk is presented as an enacted communication competence that focuses on the ongoing demands of the context and the situated practices of organizational members. Third, several factors including team members' technical expertise, task routineness, team history, time pressure and information sharing systems that influence the amount of messy talk conversations in teams are discussed. Lastly, the paper underscores the key implications of considering messy talk as an enacted communication competence on the performance and training of knowledge workers.

The presentation of messy talk as an enacted communication competence is a deliberate consideration of knowledge as an emergent, intersubjectively negotiated phenomenon that is deeply rooted in practice.

The architecture, engineering and construction (AEC) industry exists in a dynamic environment and requires several stakeholders to communicate regularly. However, evidence indicates current communication practices fail to meet the requirements of increasingly complex projects. With the advent of Industry 4.0, a trend is noted to create a digital communication environment between stakeholders. Identified as a central technology in Industry 4.0, virtual reality (VR) has the potential to supplement current communication and facilitate the digitization of the AEC industry. This paper aims to explore how VR has been applied and future research directions for communication purpose.

This research follows a systematic literature assessment methodology to summarize the results of 41 research articles in the last 15 years and outlines the applications of VR in facilitating communication in the AEC domain.

Relevant VR applications are mainly found in building inspection, facility management, safety training, construction education and design and review. Communication tools and affordance are provided or built in several forms: text-based tools, voice chat tool, visual sharing affordance and avatars. Objective and subjective communication assessments are observed from those publications.

This review contributes to identifying the recent employment areas and future research directions of VR to facilitate communication in the AEC domain. The outcome can be a practical resource to guide both industry professionals and researchers to recognize the potentials of VR and will ultimately facilitate the creation of digital construction environments.

With the increasing attention acquired from researchers and practitioners in Architecture, Engineering and Construction (AEC) industry, building information modeling (BIM) has fundamentally changed the approach we design, construct and delivery, as well as operate and maintenance of buildings and civil infrastructures. This study tries to provide an innovative perspective on BIM research. This study aims to analyze the necessity and feasibility of BIM user satisfaction research and define what BIM user satisfaction is, and then to develop a quantitative method for the measurement of BIM user satisfaction.

As it is indicated in the content, BIM user satisfaction is measured by the sum of the user's weighted reactions to a set of factors. To be specific, the entropy method was adopted to calculate the “weighting” of the factors, and the triangular fuzzy number (TFN) method was selected to compute the “scoring” of the factors. Through the literature review, methodology and tool development, as well as case study and discussions, this paper was generated sequentially.

This study found that the proposed tool for the measurement of BIM success is valid and reliable; it formerly translated the conceptual definition of BIM user satisfaction into an accurate measurement instrument. It also indicated that many factors are affecting the BIM users' satisfaction, and each of the factors inherited various importance and score, and the findings are expected to improve the performance and effectiveness of BIM management.

Through the translation of the conceptual BIM user satisfaction into a valid quantitative measurement instrument, this research provides an excellent framework for the management of BIM from the user's perspective, and it could help to stimulate user's acceptance of BIM in the AEC industry in future.

The purpose of this study is to investigate and analyse the potential of existing buildings in the UK to contribute to the net-zero emissions target. Specifically, it aims to address the significant emissions from building fabrics which pose a threat to achieving these targets if not properly addressed.

The study, based on a literature review and ten (10) case studies, explored five investigative approaches for evaluating building fabric: thermal imaging, in situ U-value testing, airtightness testing, energy assessment and condensation risk analysis. Cross-case analysis was used to evaluate both case studies using each approach. These methodologies were pivotal in assessing buildings’ existing condition and energy consumption and contributing to the UK’s net-zero ambitions.

Findings reveal that incorporating the earlier approaches into the building fabric showed great benefits. Significant temperature regulation issues were identified, energy consumption decreased by 15% after improvements, poor insulation and artistry quality affected the U-values of buildings. Implementing retrofits such as solar panels, air vents, insulation, heat recovery and air-sourced heat pumps significantly improved thermal performance while reducing energy consumption. Pulse technology proved effective in measuring airtightness, even in extremely airtight houses, and high airflow and moisture management were essential in preserving historic building fabric.

The research stresses the need to understand investigative approaches’ strengths, limitations and synergies for cost-effective energy performance strategies. It emphasizes the urgency of eliminating carbon dioxide (CO₂) and greenhouse gas emissions to combat global warming and meet the 1.5° C threshold.
