Abstract
Design Value Engineering (VE) has become an import part of the
daily design process since it has been introduced in the
construction industry. Design VE is usually conducted in the
general and execution design stages respectively. In order to
increase the effectiveness of the VE process, the outcome from the
general design VE activities should be integrated into exe- cution
design. The outcome from the execution design should be used again
for construction. In this study, a consecutive VE process model has
been presented as a way to improve the current practice of design
VE activities in the construction industry. In the presented model,
follow-up activities are emphasized to increase values from the
life-cycle perspective of a construction project. The model was
tested in a case study of an actual design VE process. The result
of the study demonstrates that the model can: 1) effectively
incorporate owners requirements; 2) assist decision making in
selecting better construction; 3) increase the interface between
general and execution design stages; and 4) trace the value flow
more efficiently. Overall, the study results indicates that a the
consecutive VE process model can be effectively applied when
construction project are con- tracted for the life-cycle management
of construction projects.
Keywords : Design Value Engineering (VE), follow-up activities,
