Recently, modular construction method has been widely applied to projects with repetitive processes including dormitory, the residential facility, and the hotel construction due to reduced labor input and shortened construction schedule. Generally, about 40% of total on-site construction cost excluding unit installation cost, is put on exterior finishing work, and thus management of finishing work is deemed important in maintaining the targeted schedule and cost. Since limited equipment is shared so that subsequent activities are not affected while carrying out on-site installation and finishing work, lifting plan becomes more important for modular projects with greater portion of finishing work load. In this regard, tower crane operation plan may take the form of a single cycle or multiple cycles in which equipment efficiency can be affected. However, difficulties exist in evaluating alternatives to tower crane operation plans supporting unit installation and finishing work. Therefore, this study aims to evaluate the alternative of tower crane operation method according to the cyclic period setting in modular building site to determine the effect on T/C uptime and process by parameterizing lifting time for unit and exterior finishing material, lift cycle for unit and exterior finishing material and time required for finishing work. Accordingly, this study develops a simulation model that can increase the tower crane efficiency by controlling the work speed. An academic contribution of this study is to suggest a resource leveling method applying the concept of lifting cycle, and further is expected to be managerially used as a basis for an alternative evaluation of equipment plan.

Due to the outbreak of COVID-19, the domestic disinfection and quarantine market has grown, and the demand for disinfection operators who want to recruit disinfectants and disinfectants who want to work has increased, but it is not easy to find jobs. In addition, there is a need for a system that can automate or efficiently manage work by hand-recording and writing a disinfection record for disinfection work. Therefore, in this paper, an O2O disinfection service system is designed using the MVC pattern and implemented through MySQL, Ejs/BootStrap view, and Node.js. Additionally, it connects with AWS cloud services so users can use the system anytime, anywhere. Through the proposed O2O disinfection service system, we hope to solve the difficulties of recruiting personnel in the domestic disinfection station market and improve the existing inefficient disinfection work process.

High-rise buildings have recently increased over the residential, commercial and office facilities, thus an understanding of construction cost for high-rise building projects has been a fundamental issue due to enormous construction cost as well as unpredictable market conditions and fluctuations in the rate of inflation by long-term construction periods of high-rise projects. Especially, recent violent fluctuations of construction material prices add to problems in construction cost forecasting. This research, therefore, develops a time-series model with the Box-Jenkins methodologies and material prices time-series data in Korea in order to forecast future trends of unit prices of required materials. BIM (Building Information Modeling) approaches are also used to analyze injection time of construction resources and to conduct quantity takeoff so that total material price can be forecasted. Comparative analysis of Predictability of tentative ARIMA (Autoregressive Integrated Moving Average) models was conducted to determine optimal time-series model for forecasting future price trends. Proposed BIM based time series forecasting model can help to deal with sudden changes in economic conditions by estimating future material prices.

This research suggests the direction realizing design business which means that designers overcome traditional role of passive design development and pursue active and subjective design development and eventually accomplish high profit by various sources except design development fee. For this, designers should be able to suggest highly successful design alternatives not by performing subjective aesthetic process but objective and scientific design development process through market-oriented information seeking, scientific design development and effective design management etc. In addition, designers should cultivates design business mind maximizing profit by various sources such as royalty, management fee and commission fee through exercising ownership, or participating distribution process and for outsourcing tasks. Regarding companies' side, they need to overcome existing manufacturing-based business paradigm focusing on rather material development, R&D, facility establishment than design or marketing, and to build design-centered business management system which menas the prior investment in design including needs identification of consumers.
