Weather-Delay Simulation Model Based on Vertical Weather Profile for High-Rise Building Construction

AbstractSevere weather can adversely affect the scheduling of construction projects. It is very important to be able to estimate the delay that would result from such severe weather because construction contracts generally differentiate between weather delays that can be anticipated and those that cannot. Only delays caused by abnormal and unforeseeable severe weather are granted a time extension. Normal and foreseeable weather delays in construction contracts are usually estimated as a monthly average of the severe weather days as determined from historical weather data, which are measured at the ground level. In high-rise building construction, however, this approach may be inappropriate because weather conditions generally vary with an increase in altitude and the height of high-rise buildings has become so great that those conditions can actually affect the construction of the upper floors. Therefore, weather delays estimated using this approach could be subject to this error. For such reasons, a simu...
