The purpose of this study is to secure the same or more structural performance and constructability for the detail off hooks cross-constructed at 135° used as external-ties standard detail in reinforced concrete columns, therefore, to the purpose of improving constructability, The clip-type binding implement was suggested. the experiment on the constructability evaluation and cost analysis of the clip-type binding implement by 90° end-hooked transverse reinforcement in reinforced conrete columns was carried out. The results of the analysis confirmed that standard detail column took about an one hour regardless of the diameter of tie. When using the clip-type binding implement, It was reduced to about 50% of the standard detail column. and regardless of the building size, it was most effective for the cost down when using the clip-type binding implement 1ea, it was about 32% fo labor cost reduction effect in comparison with using standard detail. as a result, Using the clip-type binding implement is shown be very effective in the working time and construction cost reduction.

This study proposes additional items to be recognized as defects in a defect lawsuit through a case analysis of lawsuit cases in apartment housing. Identifying these defects prevents an unexpected increase in litigation costs, delays in the date of litigation, and emotion repercussions or additional lawsuits. In this study, the defects that were not discovered by the existing occupants and construction companies, but were newly discovered in litigation, were defined as defects in lawsuits. Fifteen cases of lawsuits were analyzed and a total of 77 defects were derived. Each item was then reviewed for location, work type, number of occurrences, and cost. The results were yielded 23 defect items, which were validated by appraisers who directly appraised the cases. In addition, the derived defect factors were analyzed. Finally, the 23 defect items were categorized into 10 main factors which include attributes such as causes of occurrence and characteristics. This can provide an overall area of defects to be considered in addition to existing defect items in the life cycle of the housing. The results of this study can contribute to reducing the actual occurrence of defects and minimizing the disputes in the case of defect lawsuits.

Since the third industrial revolution has been started in the 1980s, the form of buildings has been varied and atypical by the development of building technology. Such free-form building has a curved shape unlike the existing standard buildings, and to realize this, it is necessary to manufacture the free-from panel. The shape of the free-form panel must satisfy a limited error ratio compared with the design shape, and the technology to produce free-form panels is very difficult. However, there are many problems such as enormous cost and construction waste generation when implementing free-from construction. Therefore, the development of free-form panel manufacturing technology should be made to solve the problems caused by the free-form construction. In this study, the error rate analysis of the mixed mortar panel was conducted by selecting the proper mixing ratio of the mixed mortar for the shape of the free-form panel.
