In order to improve design quality, it is necessary to develop a design review system, such as design review guidelines, and to improve the insufficient design system.
Among them, the design review guidelines need to be composed of contents that can compensate for the 'lack of construction experience' of ordering agencies and designers. However, although the number of existing design management guidelines is vast in the form of a checklist, the items and procedures for review are described only at the definition level. In other words, the specificity of detailed review content is insufficient, and the reality is that there is a large deviation in the result depending on the knowledge and experience of the person in charge of the ordering agency and the designer who performs the design review task. Therefore, it is necessary to develop a 'design review guideline'. The guideline should be composed of contents that help the review results above a certain level, regardless of the knowledge and experience of those involved in the review work. In other words, in order to secure design quality above a certain level, it is necessary to prepare design review guidelines that specify the essential contents that must be universally applied to every project.
To achieve this goal, I analyzed related data to derive a topic that requires 'preparation of guidelines'. Specifically, I identified the contents that are being reviewed mainly through the 'design review' task of the Public Procurement Service. I extracted and analyzed statistical data on about 60,000 reviews accumulated in each design review stage. Through this, I was able to identify topics that are relatively important or that designers often make mistakes when designing reviews. In addition, I analyzed the cases of design changes over the past three years (2016-2018) for projects directly managed by the Public Procurement Service, and deduced the subject of design change due to the designer's 'lack of construction experience'.
By linking the above two analysis results, I selected the topics that need to be reviewed for each construction project in consideration of the frequency and importance of the review through consultation with internal and external experts in order to improve the design quality. Next, I completed the 'design review guideline' by specifying the design review method for each of the 50 derived themes by design stage using expert advice and accumulated 'design review' contents.
In addition, I selected two topics, which are causing serious problems due to insufficient design system among 50 topics, in consideration of urgency and importance through expert consultation. Subsequently, I additionally researched improvement plans for the two design systems.
As a result, through this study, guidelines for two tasks such as 'review on adequacy of design' and 'review on feasibility of design changes' were prepared, and two design systems including 'Service that calculates the appropriate construction period' and 'Criteria for calculation of construction waste volume' was newly established or improved.
