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

• Riggingthatisnonstandardandunsymmetrical

• Fallprotection(lifelinesandwheretotieonto)

• UnchartedAsbestos,LeadBasedPaint,NORMandUniversalWastes

• Hotwork

• Unauthorizedaccesstotheworkarea

• Beingstruckbyitemsbeingremoved

• Strayelectrical

• Trappedproductandresidue

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

SafetyCommunicationsandManagement

3/26/18 26

360DegreePerpetualCommunications

• First and foremost, an excellent safety record and HSEprogram! Verify those stats!!

• Employee retention and experience;

• Financial stability & bonding capacity;

• Experience on similar projects in similar industries;

• Experience in using investment recovery to offsetcosts;

• Management and length of time in business;

WhattoLookforinaQualityDemolitionCompany

Iftheycannotexplainit,theyprobablycannotdoit!

• Every contractor should have a site specific technicalwork plan as well as a site specific health & safety planon every 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!

• Housekeeping

• 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.
