In this study, concrete pumpability was investigated using a sliding pipe rheometer when the slump was different, and the cause was analyzed by comparing the actual field pump pressure. As a result of the experiment, it was found that the concrete pumpability was greatly affected by the slump measurement value.

The fire that broke out in a residential and commercial complex in Ulsan in October 2020 was large, but no deaths occurred. For this reason, there was a difference from the previous cases, so it was analyzed through field survey. The fire was expanded to the entire building by aluminum composite panels constructed by external heat method and SMC panels in evacuation safety zones, and fire was expanded to nearby mart due to wind on the day of the fire, and there were many evacuation spaces such as 15th, 28th, and rooftop heliports.

Construction industry has become higher, larger and more complicated. It has been analyzed that the process planning in the construction site has been made by the site engineer experience mostly and some were made based on historical data. However, such plans have been investigated that require numerous revisions during construction which means that the plans made through such methods are not reliable. Numerous studies in this field have been conducted trying to solve such problems developing methodologies to overcome such limitations. It has been analyzed that many studies have focused on suggesting prediction models only that cannot be used for both actual planning prior to construction and process monitoring during construction. Therefore, this study suggests a methodology that effectively manages construction productivity by applying simulation methodology combined with bayesian approach focusing on the high-rise curtain wall operations.

Lately Construction industry has been depressing by hard construction market circumstance. Construction company, especial at this time, makes more rationalize the management of inside Company and Construction field. In this study we are to present the method of calculation reasonable duration at Reinforced Concrete Work. For the study first make up a question at field workers, then sampling the Form workers based the question. Second, We are using Work Analysis Method analysing the worker's work-method and Time. And then using the result of analysis, measure the Productivity of Form work. The productivity of Form work is used the basic data of duration at Reinforced Concrete Work

The construction industry is known to be one of the representative industries that generate fine dust. Therefore, reducing the amount of fine dust generated in construction sites is very important for the overall fine dust management. Based on this, this study proposed the concept of fine dust measurement and removal technology combined with advanced technologies such as drones and IoT. The qualitative, quantitative and risk elimination effects that can be expected when applying the proposed technique are analyzed. We will verify the effectiveness of the proposed concept through system development and field application, and evaluate specific economic feasibility through cost analysis. The proposed concept will be validated through system development and field application and evaluated specific economics through cost analysis.

In order to achieve structural performance such as rebar clear spacing in the reinforced concrete structure construction, coupler splicing joints are becoming common. To confirm the performance of rebar splicing joints, quality verification is being carried out through coupler specimen tests. However, it can be said that the required performance is reached only when the actual construction in the field is constructed under the same conditions as the coupler splicing joint specimen. Therefore, the problems and solutions of the coupler splicing joint construction of the actual field was investigated in this study.

The severity of the global climate crisis is increasing due to greenhouse gases caused by human activities. As a result, countries and industries are making efforts to reduce carbon dioxide emissions, the biggest cause of global warming. Many studies have been conducted to predict carbon emissions in the construction sector to reduce this, but they have not actually produced a highly usable formula in the field. Therefore, the two variables 'Curve Fitting' were performed based on the data of excavators and trucks measured at the field. As a result, we have obtained a carbon dioxide emission prediction model for construction equipment, and we would like to use it to help establish an eco-friendly process plan.
