조경설계와 시공의 불일치 조사분석 = The Analysis of the Discordance between Landscape Desigh and Construction

다국어 초록 (Multilingual Abstract)

The landscape industry, as a field of construction industry, has made much development together with the desire for the beautiful and pleasant environment according to the enlargement of market size, expansion of its scope of operation and national paradigm shift.
It has already been placed as a true independent field with much accumulation of technologies and development of new materials for the while etc.
However, the correctness of the drawings in design or construction is still error-prone due to non-principle, vagueness and approach with experience-based decisions, rather than scientific and rational approach. Besides, the propriety and accuracy in the construction field have not even been maintained and trial and error might be involved with waster by each cause.
Thus, as design and construction involve various types of discordances, studies on the improvement alternatives for those causes and problems are required.
The discordance can be classified into three stages;
Stage 1. The cause of discordance and problem first appear.
Stage 2. The cause of discordance is eliminated and controlled.
Stage 3. Discordance conditions are fixed.
This study presents the improvement alternatives through theoretical consideration and case studies for the causes of discordance and the stage where the problems appear.
The discordance index from the results of analysis was relatively high as 26.47 on the average for the three sites.
As for the analysis of each site by types, the common kind addition-type had the highest percentage with 29.8％ and the number change-type was 26.43％ from the results. Besides, the results of the analysis of detailed factors are listed from the highest, as construction improvement factor(23.23％), actual condition factor(19.3％) and mutual conflict factor between drawings(14.0％).
From the results of the analysis of subjects that involve discordances, constructional factor showed a preponderance(63.27％, while the design factor is 36.73％).
At present, the actualized discordance index from the results of the analysis of the potentiality was 20.772(78.46％) and the potential discordance index that remained discordant in the drawings was 5.702(21.54％).
The problems that were derived from the results of the analysis could be summarized as the quality problem in the drawings, the problems in the construction process and the problems in the process of the design change, and the improvement alternatives for those problems are as followings;
①First, the paradigm shift of the designers, the precise and thorough inspection of the drawings and the liability system for incomplete designs etc. can be considered, and
②Secondly, the importance of the original drawings is required to be understood, as the responsibility is clarified in case of a change and the improvement of the understanding of each subject is needed, and
③Thirdly, those discordances will be prevented in advance when irrational factors in the process of design change, the stage where discordances are controlled, are improved, and unfair intentions including proposal of changes out of principle, expectation of protection from liability of incomplete designs are restrained.
