The realization that concurrent engineering can be adopted in construction has led to various efforts to develop appropriate tools and techniques for its implementation in the industry. This paper discusses the role of client requirements processing in implementing concurrent engineering in construction. Client requirements processing refers to the definition, analysis, and translation of client requirements into solution‐neutral specifications for design. It is essential in maintaining focus on the client, and provides for the effective consideration, resolution and prioritization of the various perspectives within the client body. It also facilitates collaborative teamwork, compliance checking at every stage of the design and construction process, and the traceability of design decisions to explicit and implicit client requirements. The paper concludes with a description of a model for processing clients' requirements in construction, and an example of its practical application.

This paper aims to investigate the prevailing practice of managing client requirements for design and build (D&B) construction projects in Hong Kong. It attempts to evaluate the limitations and addresses the need for a practical framework for facilitating the implementation of client requirements management within the industry.

Two research instruments were used in this paper: semi‐structured interviews and case studies.

The study revealed that the limitations of the current practice included the lack of a comprehensive client's project brief, inadequate involvement of client in the briefing process, the lack of impartial agents, the controversy caused by the uncertain legal status of end‐users and the improper timing of raising requirements by key project stakeholders. Recommendations are given that an inclusive project brief is necessary in clarifying the goals and covering all‐rounded perspectives. A practical framework is needed to improve the client requirements management practice within the construction industry.

The D&B procurement system adopted in Hong Kong actually exists in various forms within the construction industry, which differ from the prototype that has long been recognized. Therefore, a more detailed study into D&B projects covering a broader area is necessary in the future.

Little research work has been undertaken on the study of client requirements management, especially for D&B construction projects. This paper has improved the comprehension of the nature of client requirements and has provided valuable insights into the prevailing problems associated with the management of client requirements.

Describes a process model for processing client requirements, which was developed in response to the need for an appropriate framework for client requirements processing in construction. The model, which is represented using the IDEF‐0 modelling method, draws from requirements processing techniques in manufacturing and requirements engineering, and its development was based on an iterative process involving practitioners from the construction industry. Uses an example of a family house project to demonstrate how the model facilitates the precise definition, analysis and translation of client requirements into solution‐neutral design specifications. Concludes that the model is of potential benefit to the construction industry in providing a first step towards client satisfaction.

The purpose of this paper is to explore the contribution of the design quality indicator (DQI) tool in the management of client requirements in construction projects, and propose a requirements-oriented project process (ROPP) to ensure continued focus on client requirements throughout the lifecycle of a project.

Direct participant involvement and case studies of building projects that have used the DQI tool are used to analyse the extent to which DQI contributes to the management of client requirements.

Case study analysis suggests that the DQI enhances focus on client and project stakeholder requirements through the initial quality aspirations set out at the beginning of a project, but it is limited in its scope to address a more comprehensive requirements profile.

The proposed ROPP model is conceptual and requires further development to test its effectiveness in enhancing focus on client requirements. However, given current developments in automated checking in BIM and other environments, this offers scope for further research in this area.

Maintaining focus on client requirements throughout the process is a key criterion for project success. However, given the many stakeholders involved, and the progressive translation into various project documents, there is a risk that focus on the original/evolving requirements of the client can be lost. Current approaches such as the DQI have limitations and a robust ROPP is, therefore, a key contribution to securing clients’ objectives over the project lifecycle.

This paper aims to focus on requirements management of projects constructed under traditional procurement system. It seeks to discuss the requirements management processes highlighting the limitations and addressing the need for a practical framework for facilitating the implementation of requirements management in the construction industry.

Two research instruments were used in this paper: semi‐structured interviews and case studies.

The literature review introduced a generic process for requirements management practice potentially to be adopted in the construction industry. The research study identified that the processes and limitations of current practice included the lack of a practical framework, misinterpretation of requirements, difficulties in identifying requirements, conflicts between expectation and constraints, complex hierarchy of client's organisation and communication problems in eliciting client requirements. Recommendations are given that an inclusive project brief and a competent project manager to manage the project requirements are necessary in capturing and tracing the requirements during the project development process. A practical framework is needed to improve the requirements management practice within the construction industry.

The research findings establish the basis for further research to examine the implementation of these potential solutions and development of a systematic framework for RsM. The research is of significant value to the construction industry where value generation is essential and critical, especially in difficult economic and financial situations.

Requirements are the foundation of the projects which are critical to the successful delivery of the projects. Although many guidelines have been published for managing client requirements, the existing practice on requirements management is still considered to be inadequate. This research provides insight for professional practitioners in the construction industry to improve the requirements management practices for development projects.

This paper introduces a building information model (BIM)‐based user pre‐occupancy evaluation method (UPOEM), which is applied in architectural design stage to narrow the gap between inexperienced clients and designers. It aims to improve the communication efficiency.

The literature review studied the related technologies applied in the UPOEM, which includes building information modeling, user activity scheduling, and requirements documentation method. Based on the building information model, a virtual environment involving the end‐users' daily activities was built up. In this virtual environment, the clients can observe how their organization will be accommodated in the built environment according to their daily work routines. A requirements and feedback interface was designed to facilitate the clients to conduct a pre‐occupancy evaluation and store the relevant information into the database.

In briefing and design stages, there is a considerable gap between the inexperienced clients and designers when the clients specify requirements and review the design solutions. In the UPOEM, the user activity simulation model can facilitate clients to obtain a better understanding of the design. The requirements and feedback interface can also help them specify requirements and give comments to the design. Thus it provided an alternative tool to improve the efficiency of the designer‐client communication.

This research established a virtual platform which involves both building information and the user activity information. This platform can be further extended by the integration of more building performance simulation tools. Thus it provided a potential to bring the traditional post occupancy evaluation process to the pre‐construction stage.

The implementation of this method in practice can improve the efficiency of the designer‐client communication, and also maximize the clients' satisfaction during the requirements specification and design review process.

This study built up a collaborative working environment for both designer and clients. It can strengthen the designer‐client relationship during the briefing and design stage.

The user activity simulation and requirements management methods are innovatively applied together to enhance the clients' performance during designer‐client communication.

This paper proposes a method for managing client requirements with the use of Building Information Modelling (BIM). The development of healthcare projects demands a large amount of requirements information, in order to deal with a diversity of clients and frequents changes in healthcare services. The proposed method supports healthcare design by adopting a process-based approach for client requirements management, with the aim of improving value generation.

Design Science Research was the methodological approach adopted in this investigation. The main outcome of this study emerged from an empirical study carried out in a healthcare project in Brazil.

The proposed method involves three stages: (1) capturing and processing requirements; (2) product and requirements modelling, which involves the connection between requirements and the BIM 3-D model and (3) supporting design solution refinement, through the communication of requirements and the assessment of design in relation to updated client requirements information.

This study explores client requirements management from a process perspective, proposing activities and their interdependences and possible sources of data, including healthcare services information. The main theoretical contributions are related to the understanding of the nature and complexity of the information involved in client requirements management, and how this can be modelled.

Requirements engineering is a crucial phase in software development. Software development in a virtual domain adds another dimension to the process of requirements engineering. There has been growing interest in virtual teams, and more specifically in virtual software development. While structured software development methods are the obvious first choice for project managers to ensure a virtual software development team remains on track, the social and cultural aspects of requirements engineering cannot be ignored. These social aspects are especially important across different cultures, and have been shown to affect the success of an information system. The discussion in this paper is centred around the requirements engineering processes of a virtual team in a Thai Software House. This paper explains the issues and challenges of requirements engineering in a virtual domain from a social and cultural perspective. Project managers need to encourage a balance between structured methods and social aspects in requirements engineering for virtual team members. Cultural and social aspects influence the relationship between the virtual team and the client.

In recent years the Large Scale Engineering (LSE) construction sector in Europe has seen profound change. This is mainly due to increasing competitive pressures from the United States and the Asian‐Pacific countries which has led in turn to increased pressures to improve competitiveness, productivity and client satisfaction. Lack of understanding of client's requirements hinders achieving such goals especially with the increasing trends of executing LSE projects in a ‘virtual enterprise’ environment. Different parties within the construction process need to understand and fulfil client's business and information requirements. Information and Communications Technologies (ICT) vendors and developers also need to understand clients requirements of systems and to align their products to them. This paper reports on findings from a study within the eLSEwise project to identify the emerging clients' business and ICT needs within the LSE construction industry and to identify the changes in clients' relationships with the supply chain and the gaps in ICT provision.

This paper aims to investigate briefing in the construction industry in Hong Kong. Specifically, it sets out to discover the current practices on briefing in the industry and the limitations of these practices.

This study consists of a literature review and a pilot study, structured focus group interviews and semi‐structured interviews.

The study has revealed that current practices, although have been in operation for a long time, have a number of limitations such as lacking in a comprehensive framework; lacking in identification of client requirements; lacking in contributions from clients; lacking in involvement of stakeholders; and inadequate time spent on the briefing. It is concluded that these limitations must be properly addressed by the industry in order to improve the briefing and to avoid subsequent problems in the design and construction phases, and that more resources should be allocated.

So far, little work has been undertaken to study the practice of briefing in sufficient depth in the construction industry in Hong Kong. This paper improves our comprehension of the nature of client requirements and provides valuable insights into the details of briefing in the public and private sectors of the local industry.
