This paper aims to examine how client requirements undergo representational and transformational shifts and changes in the design process and explore the consequence of such changes.

A series of design resources relating to hospital departmental configurations are examined and analysed using a social semiotic framework. The findings are supplemented by practitioner opinion.

Construction project requirements are represented and transformed through semiotic resource use; such representations deliver specific meanings, make new meanings and affect project relationships. Requirement representations may be understood as socially motivated meaning-making resources.

The paper focuses on one set of project requirements: hospital departmental configurations from a National Health Service hospital construction project in the UK.

The use of semiotic resources in briefing work fundamentally affects the briefing and design discourse between client and design teams; their significance should be noted and acknowledged as important.

The findings of the paper indicate that briefing and design work may be understood as a social semiotic practice.

This original paper builds upon scholarly work in the area of construction project communications. Its fine-grained analysis of briefing communications around representations of specific requirements is novel and valuable.

The purpose of this paper is to study the effectiveness of combining process mapping and system dynamics (SD) in an organization’s ongoing business process improvement projects.

Norfield Industries, designer and manufacturer of prehung door machinery, used process mapping and SD in a project targeting the improvement of its design document control process. The project team first used process mapping to document its current process and identify potential improvements. The team then developed an SD model to investigate the potential impacts of proposed process changes.

The case study supports the communication and transparency benefits of process mapping reported in earlier studies. Consistent with other case studies using simulation, SD provided useful insights into possible results of proposed process changes.

The findings have limitations with respect to generalizability consistent with the use of a case study methodology.

Organizational managers desiring to include simulation modeling in process improvement efforts have a choice between discrete event simulation and SD. SD may prove able to consume less organizational resources than discrete-event simulation and provide similar benefits related to reducing the risks associated with process changes.

The current case study adds to the existing literature documenting the use of process mapping combined with simulation modeling in process improvement efforts. The case study supports existing literature regarding the value of process mapping in making system processes more transparent. The results also support previous findings regarding the value of SD for simulating the possible results associated with scenarios under consideration for process improvements.

For many types of buildings, prefabricated prefinished volumetric construction (PPVC) is increasingly becoming a preferred alternative construction approach. Empirical evidence of project performance has consistently demonstrated that the ultimate success of PPVC projects is directly linked to the key decisions made at the outset of the PPVC project life cycle. However, there is limited knowledge of how to successfully manage these early stages. This research identified and evaluated the critical success factors (CSFs) required for the management of the conception, planning and design stages of the PPVC project life cycle.

A multistage methodological framework was adopted to identify and evaluate the CSFs for management of the early stages of the PPVC project life cycle. Based on a comprehensive literature review and expert review, a list of the 9 CSFs relevant to the early stages of the PPVC project life cycle was established. Drawing on an online-based international questionnaire survey with global PPVC experts, the CSFs were measured. The data set was statistically tested for reliability and analyzed using several techniques such as mean scores, relativity weightings and significance analysis.

The analysis revealed that the top 5 most influential CSFs for management of the early stages of the PPVC project life cycle include robust design specifications, accurate drawings and early design freeze; good working collaboration, effective communication and information sharing among project participants; effective stakeholder management; extensive project planning and scheduling; and early engagement of key players. The research further found correlations among the CSFs and proposed a conceptual framework for the management of the early stages of the PPVC project life cycle.

The research recognizes that data quality and reliability risks are the major drawbacks of online questionnaire surveys but the engagement of experts with substantial theoretical and hands-on experiences in PPVC projects helped to minimize these risks. Although small, the sample size was justified and compared with studies that adopted the same data collection approach but analyzed even smaller samples. However, the results should be interpreted against these limitations.

The findings suggest that effective management of the early stages of the PPVC project lifecycle requires early commitment to the PPVC approach in a project; detailed planning and assessment of the suitability of PPVC for the given project; and collaborative design with manufacturers and suppliers to address module production challenges at the detailed design stage. These findings practically instructive and may serve as management support during PPVC implementation.

This research constitutes the first exclusive attempt at identifying the CSFs for successful management of the early stages of the PPVC project life cycle. It provides a fresh and more in-depth understanding of how best to manage the early stages of the PPVC project life cycle. Thus, it contributes to the practice and praxis of the PPVC project implementation discourse.

Examines the importance of the design process in the development of a quality product. Discusses the concept of concurrent engineering which regards design as a process which begins at concept, and continues through physical design development and into manufacturing and involves a wide variety of disciplines such as marketing, manufacturing, business planning and finance. Outlines the use of critical parameter management to predict the functionality of a design and the design intent of a product. Concludes that critical parameter management can bring many improvements to the concurrent engineering process, bringing engineering and manufacturing closer together and bringing the customer influence into design thinking.

This paper aims to improve the seismic building design (SBD) work process for Malaysian Government projects.

Semi-structured interviews were virtually conducted to a small sample size of internal and external stakeholders from the Malaysian Government technical agency. There were seven of them, comprising Structural Engineers, an Architect, a Quantity Surveyor and consultants-linked government projects. The respondents have at least five years of experience in building design and construction.

The paper evaluates the current SBD work process in the government technical agency. There were four main elements that appear to need to be improved, specifically in the design stage: limitations in visualization, variation of works, data management and coordination.

This study was limited to Malaysian Government building projects and covered a small sample size. Therefore, further research is recommended to extend to other government agencies or ministries to obtain better results. Furthermore, the findings and proposal for improvements to the SBD work process can also be replicated for other similar disasters resilience projects.

The findings and proposal for improvements to the SBD work process can also be replicated for other similar disasters resilience projects.

This study provides an initial step to introduce the potential of building information modeling for SBD in implementing Malaysian Government projects. It will be beneficial both pre-and post-disaster and is a significant step toward a resilient infrastructure and community.

This paper aims to present the result of an assessment of the potential effect of building information modelling (BIM) adoption on the reduction of construction waste (CW) from a developing country's perspective. This was done with a view to reducing the waste generated in construction projects particularly at the design and pre-contract stages.

The study adopted a post-positivism philosophical approach, which informed the use of a quantitative research design and a questionnaire as instrument for data collection. The data gathered from construction professionals in the Nigeria construction industry were analysed using an array of statistical tools such as frequency, percentage, Kruskal–Wallis H-test, Kendall's coefficient of concordance, chi-square and exploratory factors analysis.

The study revealed five major groups of factors causing CW at the design and pre-contract stages that can be avoided or minimised through BIM implementation. These are; (1) errors in design and documentation, (2) specification and quality factors, (3) estimating and site condition factors, (4) planning of work factors and (5) procurement related factors.

The findings of the study offer practical insight for industry participants on the need for BIM implementation to reduce CW by identifying the diverse areas responsible for these waste generation.

While there has been significant literature on BIM implementation, contributions on the effect of this technology in reducing waste generation particular at the design and pre-contract stages in developing countries has been almost non-existent. This study strives to fill in this gap by showcasing the major waste generating activities that can be avoided through the use of BIM.

This study was conducted to identify, summarise, analyse and categorise mobile device applications (Apps), relevant to the construction industry and to explore their uses and exposure levels.

The research method involved reviewing literature and searching for Apps. The construction Apps were found by developing key phrases. These key phrases were used to develop search strategies, which were then used to find the construction Apps. The Apps found were categorised based on the similarity of their uses.

The 136 Apps identified were summarised, analysed, and categorised into 11 groups of distinct construction operations and tasks. The “Design and Drawing Apps”, “Measurement and Estimation Apps”, “Management Apps”, “All Round Apps” and “Construction Site Apps” recorded 29, 28, 26, 21 and 11 numbers of Apps, respectively. The Autodesk Sketchbook, GPS Field Area Measure, MagicPlan, Measure and TSheets were the top five in terms of the number of downloads. These Apps in terms of their exposure levels in the construction industry record 4.76%, 2.38%, 0.52%, 0.48% and 0.42%, respectively.

This paper provides a catalogue of the continuum of construction Apps for a wide variety of construction operations/activities which are available for construction professionals and provide guidance on their uses to assist in selecting appropriate Apps for specified operation/tasks/activities in the construction industry. Construction professionals may benefit from increased productivity, efficiency and ease of working.

Taking Community Design Centers (CDC) in the USA as case studies, the purpose of this paper is to investigate the impact of a type of service learning increasingly found in colleges of architecture. Typically, the CDC is a model of architecture's civic engagement that makes claims to “give back” to under-served communities and enhance student learning with applied architectural design work.

This project is part of a long-term engagement as participant observer and ethnographer in the field of architecture. Fieldwork in this investigation is presented as four case studies in separate and specific contexts.

Initial findings suggest there are conflicting intentions and aspirations at work through service learning in architecture and its implementation calls into question who or what is served. The author argues architecture's epistemology, pedagogical structure, and ideology precludes effective civic engagement.

The value of this research is the understanding of how those with power and resources are able to frame their work in low-income communities as service, even though there is little of worth given. It also demonstrates how stratification is reinforced through institutional arrangements in the USA.

Design and build (D/B) construction methods have gained more importance in recent years for their potential advantages in improving project performance. There are, however, a number of problems that are commonplace in D/B procurement, which, when they interact with each other, can lead to project time and cost overrun problems. The most important among them are design changes, together with communication and coordination lapses among concerned parties. Past research has focused only on the characteristics of the traditional construction, or separate sub‐systems such as different phases or human resource input to projects. An attempt is made in this paper to improve D/B project time and cost performance. A generic system dynamics model is developed that incorporates major sub‐systems and their relationships inherent in D/B constructions projects. It is validated and calibrated for a typical large D/B infrastructure project using time and cost overrun problems experienced in Thailand. Extensive simulations with many policies, individually or in various combinations, show that improvement in time or cost can be made with proper policy combinations that reflect strong interactions between the whole design and build system and can be derived only if these interactions are accounted for. To achieve overall improvement in both time and cost, the combination of full overtime schedule, average material ordering, and fast track construction with moderate crashing of design is most appropriate. If cost is the focus, extending the construction schedule, combined with material ordering based on actual need, and design and build with traditional construction method is the best solution.

Hemisphericity in behaviour studies is the role and dominance of right bran/left brain in the human brain, each side of which has varying roles and characteristics, thereby leading to different thinking orientations in the human. A study was conducted to measure the hemisphericity orientation of construction and design engineers in a large public construction organization. We know from literature that people of different hemisphericity orientations have unlike personalities and dissimilar perspectives of specific situations. The essential characteristics of hemisphericity as established in literature are presented and used in analysing the organization. From this study of engineers, it was seen that construction engineers in the organization, State Department of Engineering Construction (SDEC), are predominantly left‐brained while design engineers are predominantly right‐brained. This difference in orientation partially explains why the design and construction engineers at SDEC are unable to see eye‐to‐eye in issues concerning implementation of drawings. Left hemisphere dominant engineers are also seen to desire more organizational changes than their right hemisphere dominant counterparts. Ideally, researchers believe that a 50–50 distribution of hemisphericities in large organizations is desirable. Details, analysis, and recommendations are presented in the paper.
