Analyzing the Regional Impact of Temperature Change by Long-term Climate Scenarios on Infrastructure Construction

Abstract

The construction period is most affected by weather, and as recent climate change becomes more severe, weather conditions such as temperature, precipitation, snowfall, and wind that differ from region to region are expected to have a significant impact on air calculations in the future. As a result, the number of days not used for construction by region was determined in this study to reflect the effects of climate change in a future impact analysis. To this end, after performing bias correction on the latest climate change scenario (CMIP6) that came out through the Global Model (ESM), a comparative analysis was conducted on past weather observation data and the SSP245 and SSP585 scenarios. The rate of change was calculated for variables affecting the construction environment from various CMIP6-based ESM data, and the number of non-construction days owing to climate change was analyzed for changes in work restriction conditions by region. It was confirmed that the number of nonconstruction days in the Boeun of Chungcheongbuk-do and Jeolla-do was higher than that in other regions, and the rate of change in Busan was relatively low. Future construction plans and implementation are anticipated to be significantly impacted by these regional variations, and the computation of future construction periods is anticipated to undergo substantial modifications. Therefore, a more accurate air calculation is possible if the air is calculated by reflecting regional variations in the construction period due to climate change.
