Drying out the big easy
When it comes to cleanup after Katrina and Rita, the task is indeed big in terms of health ramifications and square footage, but there isn’t much easy about it at all. Regarding mold remediation, some spaces might’ve actually been better off staying underwater for longer, while other seemingly dry spaces could still harbor mold waiting for the first opportunity to return. Industry experts weigh in here on the tall task of ensuring that commercial occupants can breathe easy during and after rebuilding.
Hurricane Katrina was one of the most destructive storms to hit the Gulf Coast in decades. Most Americans, and indeed, many people around the world, spent the first part of September glued to their television sets, watching the never-ending scenes of devastation and destruction. These images showed stranded people on rooftops and houses and office buildings that were submerged under many feet of water.
Once the storm passed and the levees were patched, dewatering and cleanup began immediately. Areas of Louisiana, Mississippi, and southern Alabama were so devastated that it resulted in one of the largest disaster response mobilizations in the United States. Then, of course, came Hurricane Rita, which flooded parts of New Orleans all over again.
Dewatering a city the size of New Orleans was a Herculean task, but the bigger question will be: How many buildings can be restored? In the hot and sticky climate of the Southeastern United States, mold is always an issue anyway. Buildings that were submerged under water for two or more weeks will not only have mold issues, they will also potentially be contaminated from all the pollutants that were in the water. Even buildings that weren’t flooded will have problems, since many were without power for days or weeks, giving mold and mildew an ample opportunity to flourish in the non-air conditioned environment.
It has yet to be determined how long the cleanup will take, or how many buildings will be inhabitable again. In the short term, building owners, restoration crews, and government officials were removing wet items such as carpet and sheetrock as quickly as possible and using dehumidification equipment to dry out the buildings. Where water is concerned, time is of the essence, and those working frantically to restore the buildings along the Gulf Coast are hoping they haven’t missed their window of opportunity.
THINKING AHEAD
Many of the commercial buildings in New Orleans and surrounding areas sustained relatively minor damage compared to the residential areas. John Bevington, president of ChillCo, Inc. in Mandeville, LA, rode out Katrina in his home, noting with a tad of understatement that it did get “a little breezy.” His company, which services and rents chillers, is located 24 miles across Lake Pontchartrain from New Orleans. Once the storm abated, Bevington leaped into action, moving his rental equipment around the city in order to start drying out the buildings.
“I’ve been working in the downtown area, and the damage isn’t that bad, relatively speaking. The high-rise office buildings and hotels really only got two feet of water or less in their lobbies. Some of them didn’t even get that. Many of the houses, though, have been sitting in eight feet of water for almost three weeks, and they’re destroyed. Proportionately speaking, the commercial buildings did pretty well,” said Bevington.
There are three reasons why commercial buildings might have fared better than residential structures during the hurricane and subsequent floods, according to Dr. Michael Pinto, CEO of Wonder Makers Environmental, Kalamazoo, MI, and a member of the Association of Specialists in Cleaning and Restoration. “First, they are usually built more substantially, so they lose windows and drywall, but they’re built out of concrete and steel, so they’re sturdier. Second, because they’re commercial buildings, people put more importance on them in terms of trying to get them back up and running.”
The third reason is that commercial buildings usually have more resources available to them, in terms of insurance and awareness. For example, many have contingency plans drawn up and contracts already in place, so they are ready for most emergencies that could come their way. Nick Sickmen, marketing manager for Carrier Rental Systems in Houston, agreed, noting that his company had rental equipment in place at many locations two to three days before the storm.
“The companies that have plans in place beforehand know that generators, air conditioners, and drying equipment go fast. There’s only so much of this equipment in the rental market,” said Sickmen. “In times like these, where the devastation is so massive and with Hurricane Rita coming in right after Katrina, the amount of rental equipment available is limited.”
PROPER PROCEDURE
Nonetheless, cleanup in the New Orleans area has been moving rapidly, and many are worried that it may be moving just a little too fast. Bevington noted that FEMA initially was so desperate for hotel rooms for its workers, that the organization was signing one-year leases with anybody who could give them a number of rooms immediately.
