Atlantic hurricane season is underway, and year after year, record-breaking severe weather impacts the nation’s coastal areas near the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. 

Hurricanes can be unpredictable, and it takes a dedicated, experienced, and well-prepared contractor to think ahead of a storm. From property and equipment damage to production downtime and recovery costs, severe weather not only threatens the successful delivery of construction projects but also endangers the safety of people. 

As a leading Buildings and Civils infrastructure contractor, �۽�ֱ�� draws best practices and supports the collaborative execution of storm preparedness plans across a wide array of project types and geographies. 

Through effective planning, leveraging innovative technologies, and taking precautions to secure active construction sites, �۽�ֱ��’s Zero Harm approach to storm preparedness equips our teams for the unpredictable and keeps the safety of our team members, partners, the public, and our owner’s projects top of mind.   

Building Around Severe Weather

At �۽�ֱ��, storm preparedness planning always begins before putting the first shovel in the ground. Severe weather is often unpredictable, and storms have the potential to intensify and can rapidly change paths. This makes it vital for project teams to be well-versed in proactive storm procedures to quickly and safely act when the unexpected approaches. 

“Every part of our business across the nation experiences weather distinctly unique to the location of where we build,” says Christopher Diaz, �۽�ֱ�� US Buildings vice president of safety, health, and environmental in Florida. “Our regional teams structure the delivery of projects based on the weather they may have to withstand during and after construction. The way we build in one part of the country is different from how we build in another, and our local teams’ expertise in their respective areas has successfully and safely delivered projects through a variety of weather conditions.”

Prioritizing the safety of team members, partners, and the public always remains constant through �۽�ֱ��’s operations. During severe weather, our teams disseminate safety information to project teams and their families which includes emergency contacts, shelter locations and a checklist of actions to take, and key supplies. Teams also ensure that potential high-danger equipment and materials are safely secured to mitigate the risk of endangering those who may come in contact with our work.

Securing High-Danger Equipment

At any point in a project’s schedule, teams may need to secure tower cranes, loose materials, electronics, computers, scaffolding, crawler cranes, lattice boom cranes, and rebar columns to protect the workforce, the project, and the public.

Tower cranes require an additional level of planning. When selecting the appropriate tower crane, teams must first determine if it can withstand wind speeds from a potential storm system. For Category 4 hurricanes like Hurricane Harvey and Hurricane Florence, sustained winds can range between 130 mph and 156 mph according to the . When facing storms of this magnitude, project teams must take appropriate precautions to safely secure or dismantle tower cranes. 

“Designed like a wind vane, the appropriate tower crane can withstand high windspeeds if it is allowed to rotate freely with the wind during a severe weather event,” says Diaz. “Every aspect of our operations for US Buildings projects is focused on wind cycles of storms and preparing for the safe mobility of cranes during severe weather.” 

�۽�ֱ�� teams collaborate with experienced engineers who help monitor construction equipment and can advise a crane’s wind capabilities based on forecasted weather predictions. If a crane on-site cannot withstand the projected wind speeds of an impending storm, we may choose to lower the overall height or even consider dismantling it. 

Our team members account for the removal and erection of cranes in project schedules and budgets to mitigate any potential loss of production time or additional project costs. However, during significant storms, tower crane owners have multiple pieces of equipment to prepare in the forecasted area, and dismantling and erecting incurs an additional cost. By incorporating these time-sensitive elements in the project planning stages and being aware of weather forecasts, �۽�ֱ�� ensures our teams are empowered to take quick and decisive action.

For highways, long-span bridges, and other civil infrastructure projects, crawlers, and lattice booms are logistically relocated out of low-lying areas, and lattice booms are secured to the ground to avoid storm damage. On water and wastewater projects, tower cranes may also be disassembled depending on forecasted winds and their engineered limits. 

For hurricane, wind, and rain events, supporting rebar columns are also a part of the preparation for Civils operations and require additional monitoring when a storm moves closer to a job site or if a storm changes its path. 

Executing Stormwater and Erosion Control Devices 

In the case of heavy rain, flooding, and rising seawater issues, stormwater controls are necessary in keeping projects sustainable and safe from erosion and pollution. 

For US Buildings operations, sandbags are placed around the perimeter of job sites to divert turbid, muddy floodwater and prevent pollution in local waterway systems. Projects located in coastal planes also experience low and high tide sea levels that can rapidly cause flooding. Non-stop dewatering controls may be necessary to ensure infrastructure is safely out of the ground and protect against corroded building foundations.

“It only takes a couple of inches of rain for flooding to greatly impact the schedule and delivery of a construction project and these rain events don’t necessarily have to be at the project site. Significant rain upstream can have an impact on our operations downstream,” says Eric Yates, �۽�ֱ�� US Civils environmental health and safety manager in North Carolina. “We find that researching historical data for flooding in the project area gives us a good idea of what we can expect. Our Civils business relies heavily on our erosion control devices to mitigate erosion and sediment in low-lying areas. When experiencing heavy rain and flooding on our highway and bridge-span projects, we take additional measures to avoid silt entering waterways or large bodies of water.”

Flooding and erosion can have devasting impacts on job sites and require extensive and well-executed quality control measures to keep projects safe from damage. An all-hands-on-deck approach to mitigate risks of flooding, sediment, and erosion is relied on to quickly dry out a construction site and return to work as soon as safely possible.   

Weathering the Storm Through Innovative Technology

Improved forecasting and real-time monitoring systems have significantly enhanced storm preparedness. These innovative tools can alert our workforce nearly 10 days before severe weather, giving teams ample time to execute storm preparedness procedures. 

“Our teams have many years of experience in safely securing a construction site to protect our workforce, projects, and the public,” says Yates. “We review storm prep protocols at our job site locations throughout the year for all types of weather and several times a year for tropical storms and hurricanes. With the help of forecasting technology, we can accurately pinpoint a storm’s location 24/7, and this is even more helpful if storm trajectories change so we can be agile in safely adjusting our operations accordingly.”

Teams also leverage drone technology for aerial monitoring and inspections as storms unfold. Before initial impact, teams capture 360-degree videos and images of entire project sites and use this footage as a baseline to assess job sites post-storm. Once storms have passed, drones are flown over job sites to accurately pinpoint and document damage such as erosion, flooding, and loose materials. The drone footage also provides key intelligence regarding when it is safe to allow our workforce to return to the job site. 

Communication is a key priority during inclement weather. To effectively communicate storm forecasting, project status, safety protocols and the status of project operations, text alert systems are used to rapidly broadcast updates to our teams and partners located in areas of potential impact. In the instance of intense lightning, these communication tools aid in informing team members and partners of lightning stand downs and when to seek shelter before a storm approaches.
