Howisdemolition,comparedtoconstruction,anentirelydifferentanimal?

• Modern demolition is mostly mechanized sothere are fewer man-hours
• Demolition crews are normally considerablysmaller than construction crews and jobclassifications are different
• There are very few formal classes to learn thetechniques so mentoring in demolition is morethe norm than the exception
• Demolition contractors must be more diversified
DemolitionasComparedtoConstruction
• Management of change is in reverse in demolition(taking it down versus putting it up)
• Many demolition projects are short-term
• Crane and rigging is more flexible in demolition, butwith more hazard considerations
• Accurate drawings are a rarity in demolition
• There are more unknowns in demolition both aboveand below ground

ChallengesonDemolitionProjects
• Structural fatigue of walk ways and ladders and itemsbeing lifted;
• Lack of understanding by clients (sometimes thesafest way to take something down is to let it fall,known as a controlled fall)
• Ineffective safety and technical work plans
• Poor training and mentoring of workers
• Failure to make all workers aware of the big picture ona project

• Every worker should understand and sign-off on thatplan before being allowed on the project!
• Every worker should have the right to stop all work ona project if they perceive a safety hazard might exist!

• BBS is the study of human behavior as it relates to the tasks thatare performed on a jobsite;
• The BBS Program is proven to prevent accidents by predicting thefuture from past metrics;
• Do not reinvent the wheel, but rather adjust the thought processof the workers to meld into an ever changing work environment;
• Perpetual change in the work environment on demolitionprojects makes it challenging to recognize and track trends.
• Use the BBS Observations to develop trends and influence aneffective blend of worker attitude & worker behavior.
