Planning of construction operations and projects must take into account weather conditions and the resulting impacts on the project schedule. Predetermination of weather and its resulting impacts on a construction schedule will allow management to implement a program to effectively deal with its effects. A methodology for incorporating weather effects must include the identification of activities subject to delay as a result of adverse weather conditions, a model for determining the degree by which an activity is affected, and a recording mechanism by which the results are maintained for analysis. This paper summarizes a simulation model which generates weather conditions. modifies the construction schedule to reflect the conditions generated, and records activity and total project duration as probability distributions after a number of simulation runs.
