Identification and Evaluation of the Influencing Factors in Target Value Design Process through an Industry Survey

Target value design is a new practice in the construction industry promoting concurrent engineering and collaborative design. This paper shows the results of literature survey to identify the influencing factors in the target value design. The paper also presents the results of a questionnaire survey to explore the industry practitioners' perception of the relative importance of the influencing factors. Project stakeholders participating in the survey consider the integration of different project stakeholders in the design phase as critical. The project definition is also regarded as essential in implementing the target value design. However, the market conditions and project attributes are considered as least significant in the target value design process.

Proposta de processo para o desenvolvimento de projetos de empreendimentos públicos

The design and budget development process of public projects is done in a fragmented way by the stakeholders. This situation contributes to several inadequacies in construction projects, related mainly to costs and deadlines. The aim of this paper is to propose improvements to the process, based on Target Value Design (TVD). The investigation was done through qualitative research, and the research strategy used was a multiple case study. It involved four public institutions, comprising project the development, budget and inspection sectors. The study included the following participants: clients, managers, designers (architect and engineer), budgeters, and works inspectors. Seventeen participants were interviewed during the study. This paper presents a design development process model for public projects (DDP).
