Weather conditions can be highly unpredictable and difficult to plan for. To counteract this, many contracts will identify adverse weather within the extension of … weather conditions is necessary. Rain, winds, or freezing temperatures can make work by certain trades less efficient, or worse, impossible. Still, there are some common culprits of construction delays. Therefore, in this study, we propose a method for calculating construction schedule delays where weather conditions are taken into consideration. Principles to determine the impact of weather delays on construction projects. When weather condi-tions create safety hazards (eg. The impact of (adverse) weather is a common cause of delays, legal claims and economic losses in construction projects. A contractor may also be able to claim costs if it is pushed by owner delays into bad weather. If you’re doing an indoor renovation or refurbishment project, you probably won’t get away with using the weather as the reason you’re behind schedule. These are just a few of the most common causes of delay. The general rule is that if the contract is silent on weather delays then these will be the contractor’s responsibility. The delays must actually impact the schedule. Under the construction contract, who is responsible for weather based delays? This means you have to plan for weather delays as well as cash flow concerns that might accompany those delays. Weather. Poor Weather. Abstract. Conversely, if a contractor’s work is delayed by the owner’s delays, it may have a strong argument for any delays it incurs as it tries to complete the work in less-than-optimal weather conditions. earthwork in rainy conditions), contractors delay work until conditions im-prove. The causes of delays on large-scale construction projects are many and varied; changes orders, financial issues, adverse weather, supplier delays, poor design, lack of experience (owner or contractor) or unforeseen ground conditions. structural steelwork in icy conditions) or poor productivity (eg. weather is considered by contractors, architects, and en-gineers to be the most prominent cause of lost time and delays on construction projects [l]. The point is that “unusually severe weather” on a Nashville construction site may be different than a site in the nation’s capital. Most contracts that provide for time extensions for weather delays grant time, but not money, either under a so-called no damages for delay clause, or under the specific provisions for time extensions. Adverse weather during construction - Designing Buildings Wiki - Share your construction industry knowledge. Here are the five most common causes of construction delays and what you can do about them. This methodology combines weather information, the expected delay to particular types of construction as a result of altered weather conditions, and Research has recently been carried out aimed at incorporating the effect of weather in project planning; but these studies have focussed on either a narrow set of weather variables, or a very limited range of construction activities or projects.
