In the construction sector, facing setbacks and delays can lead to significant financial repercussions and considerable extensions in project timelines.

Setbacks resulting from inadequate communication and overbooking are consequences of human error and are entirely preventable.

However, there are delays that arise from factors beyond the contractor’s control, with adverse weather conditions being a prominent example.

Reducing impact of weather on construction

Each season brings distinct weather patterns, such as spring’s rainfall, summer’s dry heat, fall’s cooler temperatures, and winter’s snow and ice.

These conditions pose threats to materials and machinery, create potential safety risks for workers, and disrupt the timely completion of projects.

While weather is uncontrollable and occasionally unpredictable, its negative impacts and disruptions can be effectively managed. Here are several recommendations to mitigate the effects of adverse weather on construction projects:

Stay Informed

Keep abreast of current weather patterns and reports. Despite the occasional inaccuracies in weather forecasts, it is crucial to remain vigilant on the job site, watching for ominous clouds and responding promptly to any suspicious signs.

Preventing Weather Delays:

Proactive measures can mitigate weather-related disruptions in construction projects. Monitoring weather reports, scheduling critical activities on clear days, storing materials strategically, and initiating trenching activities during dry periods are effective strategies. Installing windows and exterior facades early in the construction process safeguards interior work from potential damage.

Assessing Weather Events:

Not all weather events warrant time extensions for construction delays. Construction contracts play a pivotal role in outlining recourse for weather-related delays. Criteria such as the event’s occurrence within the original timeline, its impact on the critical path, adherence to contract terms, and proper documentation are crucial in validating a weather delay.

Weather delays rank among the top external causes of schedule disruptions in construction projects. Cold temperatures and early snowstorms during the earthwork phase, for instance, hinder concrete pours due to minimum curing temperatures. This delay subsequently affects activities like placing support columns or concrete footings, thus impacting the entire project timeline.

“Topping-out ceremonies,” marking the completion of vertical construction, initiate a rush to install the roof and make the building weathertight. Until this stage is achieved, interior construction is limited to prevent exposure to the elements, emphasizing the interdependence of weather and construction progress.

Reporting Unsafe Conditions

Establish a system that facilitates anonymous reporting of unsafe working conditions by employees. This system enables supervisors to respond promptly and implement necessary solutions.

Rainy weather with driving winds leading to water infiltration inside a building can have cascading effects. Prolonged delays due to water-related damage, such as mold growth, impact subsequent activities like flooring, cabinetry, and painting. Such delays not only affect project completion but also impact the contractor’s profit if weather delays were not accounted for in contract negotiations.

Prioritize Weather-Independent Tasks

 Identify tasks that can be performed away from the elements or indoors. Schedule the completion of these tasks on days when adverse weather is anticipated.

Site Protection Measures

 Move equipment indoors during inclement weather to prevent damage. Secure and cover materials and equipment that cannot be relocated.

Heat-Related Illness Prevention

In the summer, when temperatures can be extreme, ensure workers stay hydrated and use appropriate sun protection. Install water stations throughout the job site for easy worker access.

Electrical Safety

In rainy or wet conditions, ensure all electrical cords are shielded from exposure to prevent accidents.

Despite the challenges posed by unfavorable weather conditions, proper planning and training can minimize the impact of Mother Nature on project completion.

Construction companies in Portugal, like their counterparts globally, grapple with the impact of weather on project timelines and overall progress. The meticulous coordination of construction activities, adherence to pre-construction meetings, and the implementation of proactive measures to mitigate weather-related disruptions are paramount.

Whether dealing with the construction of high-rise apartments or other vertical structures, the need for constant weather monitoring and strategic planning remains crucial in the Portuguese construction landscape. By aligning with effective project management practices and considering the specific weather patterns in Portugal, construction companies can navigate challenges and optimize their processes for successful project completion.

Conclusion:

Weather delays pose challenges in construction projects, impacting cost, schedule, and quality. Prudent communication about potential weather risks among stakeholders, workers, vendors, and suppliers can contribute to effective mitigation and alleviate the consequences of delay claims caused by weather events during construction.
