<\/a><\/p>\nEven one disruption from thunderstorms, lightning, or a tornado, can have a domino effect on the rest of the supply chain, which can cost thousands of dollars in downtime and profit leaks. The Atlantic Hurricane Season may produce up to 9 named storms, 4 hurricanes, and 1 intense (category 3 or greater) hurricane. Construction sites that are not properly secured from a major storm could experience delayed or indefinite completion dates, which can eventually cost them their reputation or their next job. Extremely high temperatures put personnel in danger of heat-related illnesses, including exhaustion, fainting, rash, cramps, or worse, stroke. Near coastal environments, heat combined with humidity can further damage the human body since humidity reduces the amount of sweat that the body needs to cool off.<\/p>\n
Heat Hurts, Humidity Kills<\/h2>\n
From scheduling delays to reduced personnel safety, legal liabilities, and profit leaks, summer wreaks havoc on even the most seasoned of construction workers. There is a way to avoid such weather interferences.<\/p>\n
For heat disturbances, there are several internet-based indices available to provide data; however, in situations where humidity contributes to life-threatening situations, a more detailed assessment is needed. In environments with extreme humid conditions, the proprietary Modified Discomfort Index (MDI) is a tool used by many companies as part of their Heat Injury Prevention Plan. To calculate MDI, construction site managers add ambient (air) temperature (Ta) to wet bulb temperature (Tw), which is found via local weather reports. The formula is as follows: MDI = (.3 x Ta) + (.75 x Tw).<\/p>\n
Besides monitoring heat and humidity reports hourly, employers can also implement the following tactics to protect personnel, including:<\/p>\n
- \n
- Gradually increasing an employee\u2019s workload if he\/she is new to the environment;<\/li>\n
- Offer an air-conditioned trailer with appropriate refreshments;<\/li>\n
- Introduce work-rest cycles with relief workers rotating in shifts;<\/li>\n
- Reschedule projects to cooler times of the day, such as the evening; and<\/li>\n
- Encourage self-monitoring where employees can take personal breaks if they feel overheated.<\/li>\n<\/ul>\n
Tropical Troubles<\/h2>\n
While summer\u2019s clear skies are a desirable time of year to work on construction projects, these assignments are routinely disrupted by hurricanes, tropical storms, and thunderstorms, producing high winds. By implementing the following timed phases for efficient operational shut downs, companies can safeguard personnel, reduce profit losses, and return to work as quickly and efficiently as possible.<\/p>\n
Phase One: (Four to Five Days Out)<\/h3>\n
- \n
- Determine a shut down timeline\u2014Often businesses decide on evacuation plans based on when a hurricane makes landfall. This can be dangerous as damaging winds may arrive up to 12 hours before the storm. Recently, many workers have determined shut down based on wind strength. For example, if a site cannot safely work with winds in excess of 48 mph, they will shut down.<\/li>\n
- Identify resource needs\u2014Identifying a site\u2019s resources is an opportunity to see what employees, products, equipment, and supplies the project has available or needs to address prior to shutdown.<\/li>\n
- Answer critical questions:\n
- \n
- What is the facility\u2019s operational schedule for the next couple of days and who will be affected?<\/li>\n
- Does the company need to facilitate deliveries to and from the site?<\/li>\n
- In the event of damage, does the site have a vendor or team who can clean up the location?<\/li>\n
- Based on recovery efforts, how quickly can employees return to work?<\/li>\n<\/ul>\n<\/li>\n
- Communicate with key team members\u2014Key team members are clients, employees, vendors, corporate executives, local government agencies, and supply-chain workers who will be affected by the site\u2019s delays and\/or closures. On-site managers should have each of their employee\u2019s and contractor\u2019s personal contact information to communicate critical updates following a storm.<\/li>\n<\/ul>\n
Phase Two: (Two to Three Days Out)<\/h3>\n
- \n
- Release non-emergency personnel to evacuate\u2014If there is a team that needs to assist with shut down until the arrival of the first threshold, they should have already attended to their personal plans.<\/li>\n
- Continue site shutdown\u2014No additional deliveries should be made during this time. The construction zone can continue its protocol for shutting down and removing any non-essential product and supplies.<\/li>\n
- Continue monitoring the storm\u2014This is the time to review a project\u2019s worst-case-scenario to maintain the safety of personnel and equipment.<\/li>\n<\/ul>\n
Phase Three: (Less than 48 Hours Out)<\/h3>\n
- \n
- Facilitate a final walkthrough\u2014This is the last chance to secure or transport outstanding materials.<\/li>\n
- Place vendors on standby\u2014Storm surge, high winds, and hurricane-producing tornadoes could damage a construction site. Managers should advise their clean-up vendors to be on standby.<\/li>\n
- Evacuate\u2014Remaining personnel and management should evacuate.<\/li>\n<\/ul>\n
Mark Twain once said, \u201cClimate is what we expect, weather is what we get.\u201d Even though construction workers can\u2019t guess the weather\u2019s next move, these business continuity tools can help workers avoid monetary penalties from lengthy delays and more importantly, protect outdoor personnel from weather\u2019s unpredictability.<\/p>\n
