This methodology combines weather information, the expected delay to particular types of construction as a result of altered weather conditions, and To counteract this, many contracts will identify adverse weather within the extension of … structural steelwork in icy conditions) or poor productivity (eg. A contractor may also be able to claim costs if it is pushed by owner delays into bad weather.
