Accident Prevention

• Accident prevention is not about achieving p gZERO risk, but rather about achieving ZERO accidentsZERO accidents.

• This is achieved by ensuring that safety b i d i d i t l th tbarriers are designed appropriately, that they are installed and functional, that they are cleaned and maintained, that instruction in their use is provided andinstruction in their use is provided and finally that people are motivated to act in a safe mannersafe manner.


Safety Barriersy


Safety Barriersy

Physical Safety Barrier Behavioral Safety Barriery y– They are constructed and

designed appropriately

y– Procedures, plans, rules and

goals– Installed according to

purpose,– Availability of good personnel

and planning– Used as prescribed,– Checked continually and

– Competences and adaptation of personnel and tasks

– Maintained in good condition

– Commitment, involvement and endeavouring to resolve conflicting situationsconflicting situations

– Coordination and communicationcommunication

Safety Barriersy• Passive safety barriers are those that are incorporated

i t th t h l d t d hi hinto the technology, process, procedures, etc. and which prevent undesirable events from occurring. These include technical safety precautions automatic processinclude technical safety precautions, automatic process procedures, targeted safety routine, etc.

• Active safety barriers are those that need to be learnedActive safety barriers are those that need to be learned by the individual so that he or she through his or her behaviour prevents undesirable events from occurring. These include safety instructions, safety procedures, safety standard and routines.


What We Need to Do?

• How do we ensure that such simultaneities of factors that can result in accidents do not arise?

• How do we create awareness that “simultaneities” can occur so that people have an opportunity to take the appropriate action?pp y pp p

• How do we ensure that people what they should do when they are in situations where ado when they are in situations where a simultaneity of factors arises that can lead to an accident?accident?

Virtual Construction Model Creation

• The aim of Virtual Construction Model is to show and t th t tipresent the construction process.

– The Virtual Construction Model should cut down the As-Design / Construction BIM model to many assembly models for present the y y pconstruction process.

– Add the construction works resourcesl such as formworks, temporary works etctemporary works etc.
