Tips from a Commercial Demolition Company

first_imgThe demolition of a building is a carefully orchestrated, thoroughly researched affair. Demolition contractors must be conscientious about both employee safety and environmental safety, or else risk losing their business licenses. Just like general contractors, demolition experts are required to follow OSHA standards for employee safety. And demolition firms must also abide by EPA standards guiding environmentally safe deconstruction techniques. Hazardous construction materials, such as asbestos, must be safely removed before a building can be demolished.Some forward-thinking demolition companies are exceeding government standards and are finding innovative new ways to reuse old building materials, rather than sending them straight to the landfill. Because they have a unique perspective on how to best take down buildings, commercial demolition experts can teach residential contractors quite a bit about material selection, building methods and more.

This information can come in handy when residential builders are selecting earth-friendly building materials. From a commercial demolition perspective, the materials listed below can effectively be recycled upon demolition. In fact, with disposal costs as high as they are, it’s often worthwhile to pay for the labor it takes to separate them out.Concrete. A single demolition project can yield tons of concrete. Fortunately, this concrete may be crushed into gravel, a high-demand material in new building projects. Some industrial demolition contractors even employ enormous, mobile concrete crushers that can easily process all concrete on-site.Steel. With the right equipment and expertise, steel and other scrap metals can be processed for recycling into new products.Interior doors and beams. Wood doors, posts and beams in good condition can often be sold or reused – there are plenty of architectural salvage companies that are interested in these types of materials. If the condition is too poor for reuse, the wood can be recycled.Sinks and toilets. Again, if they’re in good condition, these fixtures can usually be reclaimed by an architectural salvage company. Otherwise, porcelain models can be recycled with the concrete, while stainless steel fixtures can be recycled with the other scrap metals.Construction and demolition are the two ends of a building’s lifecycle, so it makes sense that those responsible for each phase would have plenty to teach each other. If your contracting crew could use an injection of fresh building knowledge, consider learning from a demolition expert. Fall protectionBecause demolition companies are in the business of tearing things up and creating holes, they’re acutely aware of the importance of fall protection. When working around any hole, open wall or open roof with a fall greater than 6 feet, demolition workers are typically required to wear full body restraints. These same hazards are often present during the construction phase, as well, which means fall protection is just as important for builders. Focusing on the eco-friendly lessons of demolition has a definite cost-value for residential builders, who have seen a spike in consumer demand for green construction. Cradle-to-cradle building techniques that anticipate green demolition down the road can contribute points to LEED certification – the Holy Grail of earth-friendly building. The following is a look at some of the things industrial demolition contractors urge residential builders to keep in mind.center_img Elder Demolition is a fully licensed and insured demolition company based in Portland, Ore., with certifications for hazardous waste handling as well as broad experience with LEED-certified green demolitions. Limiting exposure to dangerous chemicalsOf course, residential building contractors are aware of the dangers of asbestos, lead and other hazardous materials in home construction. No new homes contain these toxins, but it’s not unusual for residential contractors to be hired for retrofitting work to bring an older home up to code. Here are a few examples of irritating but not illegal hazards residential construction workers could see while working in older buildings:Synthetic mineral fibers (SMF). These are fibrous products made from ceramic, fiberglass and rock wool. Studies have found that SMFs aren’t as noxious as asbestos, so they are still used in sound and thermal protection products. Irritation to the eyes, nose and throat is the most common symptom of SMF exposure, but some question whether SMFs could also cause lung cancer, since they sometimes contain fiberglass. Industrial demolition experts recommend requiring workers to wear respirators and protective clothing when SMF contact is possible.Wood dust containing formaldehyde. This wood dust can become stuck in the nasal passages when inhaled, and it is thought to have caused nasal cancer in some woodworkers. Wood paneling and particleboard sometimes contains the toxic substance formaldehyde; when the wood is cut or otherwise manipulated, formaldehyde-laced dust is sent into the air, posing a major risk for nearby workers. For this reason, demolition contractors recommend wearing protective respiration gear when dealing with particleboard and paneling.Lead paint. One hazard that’s frequently overlooked is the danger of torching steel beams that have been painted with lead paint. Simply cutting a few painted beams can expose a builder to airborne lead levels that are off the charts. In these cases, OSHA requires workers to be provided with respirators, protective clothing and hand washing stations.These are only a few of the materials demolition companies must carefully monitor and prepare for when taking down buildings. Indeed, OSHA has an entire set of standards for demolition procedures. If your team isn’t confident in this area, consider consulting with a commercial demolition professional. A longstanding demolition company will have wide-ranging experience in taking down everything from air traffic control towers to factories. Their experts can provide unique insight into how to best remove chemical hazards.last_img
