AD - Steel Erection and Crane Lift Audit

Contractor must ensure workers carrying out, or the person directly supervising rigging work must hold a WorkCover certificate of competency of the appropriate class. Is contractor compliant?

Does the Contractor manage the erection of structural steel with cranes, hoists or other mechanical loadshifting equipment to ensure employee has a certificate of at least class RB (basic rigging)?

Does Contractor insist that the riggers show him their certificates? And does he keep an up-to-date site register of certificate holders?

Has the Contractor / Subcontractor ensured that the employees are competent with the particular plant and equipment to be utilised on this work? Is that competency / training entered in the site register?

Are Contractors riggers and crane operators properly certificated?

Has the Contractor planned the order in which the various components and members of the structure are assembled and will it maintain stability at all stages?

For larger lifts has the contractor prepared a lift plan with mass of load, lift radius and proposed crane?

How is Contractor managing for the effects of high winds on partially completed structures, or winds occurring during the lift? Please comment.

What arrangements has the Contractor considered in regard to temporary guying with well-anchored and correctly tensioned flexible steel? Please comment.<br>Wire ropes may be necessary to stabilise incomplete structures overnight.

Has the Contractor verified the calculated mass of the lift, and reviewed the detail of any proposed rigging and lifting plans?

Does Contractor have sufficient craneage for the job?

Has the Contractor pre-planned the lift to ensure cranes are positioned so that they can lift and position structural members while staying within their load chart safe limits at all times?<br> Failure to do this can result in structural damage to the crane or the crane collapsing by becoming unstable.

Has the Contractor ensured all lifts can be done while keeping a safe distance from powerlines and obstructions, never operating over road traffic or unprotected public space and never lifting over unprotected site offices or amenities sheds?

Check requirement to have power lines isolated. Comment

Ensure trained riggers, dogmen, crane drivers are used for the lift. Are they?

Is the contractor compliant and have they obtained the correct permits?

Contractor to ensure all mobile cranes are properly set up on stable ground. Except where they can operate safely "on rubber", mobile cranes should be set up level on properly packed and fully extended outriggers. Has contractor ensured this?

Has the Contractor discussed the lift and the pre-planning with the employees who will be actually carrying out the lift?

Has their input and advice been incorporated into the plan?

Are all parties, comfortable and are communication system clear and functioning?

Where two or more cranes are operating, they should be sited so as to prevent them from operating within each other's airspace. Has the contractor ensured this?

Contractor should plan the work so far as space permits, so sections of the structure should be assembled at ground level before they are lifted into their final position to reduce the need for working at heights. Has contractor properly considered and implemented this?

Contractor should where practicable ensure that he has braces fixed to tilt-panels, and structural items prior to lifting. Has contractor properly considered and implemented this?

Contractor to consider wherever possible, fix temporary guard railing to tilt-panels and perimeter structural beams before they are lifted, to provide perimeter protection for roof workers. Has contractor properly considered and implemented this?

Contractor to consider if Slings for columns can be fitted with remote-release shackles so the slings can be disconnected from below. Has contractor properly considered and implemented this?

Review Contractors system to make sure all work at heights is done from safe working platforms wherever these can be provided. This means providing elevating work platforms (such as scissor hoists or boom lifts), mobile scaffolds, securely fixed portable ladders or crane-lifted workboxes. Document findings.

Where the Contractor has determined it is necessary for erectors to work from the structure itself and it is not practicable to provide temporary platforms or temporary edge protection, ensure the workers are using safety harnesses attached to anchorages with a safe loading capacity of at least 1.5 tonnes which are set up to prevent lanyards or inertia reel lines from being cut through on sharp edges.

Review Contractors arrangements to ensure he never allow erectors to work at height without proper fall protection, never allow erectors to climb or slide down columns, and never lets riggers walk steel, or ride loads of steel into position.

Have safety issues been discussed at tool box meetings, OH&S meetings, and lift planning meetings?

How has Contractor encouraged employees at height to keep safety harness clipped on? Comment.

How does Contractor ensure structural members are being correctly secured? Comment with reference to the following questions.

Contractors system to ensure all bolts, nuts and washers used in structural connections are the type specified on the design drawings? Detail system

Contractors safety and quality system to ensure braces for tilt-panels are of sufficient capacity, as specified on the drawings, are correctly bolted to the panel and supporting structure, and have locking pins which are fitted with safety clips to prevent them from working free. Detail system.

Contractor to ensure where bolts need to be tightened to a specified tension, make sure they are checked with a tension wrench and marked as checked. Is contractor compliant with this?

Contractors pre lift checks to ensure that all structural welding conforms to the design specifications. Detail checks

• Contractor pre planning should not focus on trying to lift loads with two or more cranes unless it is has first been determined that it is not practicable to get a single crane with enough capacity and reach to do the job. <br><br>• Where multi-crane lifts are needed, The Contractor should try to use cranes of the same type and capacity. <br><br>Has the aforementioned information been taken into consideration?

• Contractor must make sure a rigger who holds at least the RI (intermediate rigging) class of WorkCover certificate is fully in charge of the lifting operation and has made the requirements of the lift clear to all crane operators, dogmen and any other participating workers. <br>Is contractor compliant with this?

Contractor to ensure the cranes' safe lifting capacities at the maximum required radius have been properly calculated as being at least 20% above their share of the load (for two cranes), 33% above their load share (for three cranes) or 50% above their load share (for four or more cranes).<br>Has the contractor ensured this?

Contractor should never allow a multi-crane lift to be done in gusty or strong winds, or when strong winds are imminent. Is contractor aware of this and compliant?

Contractor should ensure / encourage the lift team do have a on site discussion and a "dummy run" with the cranes before the lift is attempted. Has contractor done this?

Has Contractor ensured any multi-crane lifts being done safely?

Hoisting rope condition

Condition of load hooks

Attachment of over hoist limit

Condition of rigging gear

Where is the lift to take place?

Check the ground conditions where the lift is to take place .i.e muddy, clay, sandy, sloping ground, proximity to trenches or recently filled excavations.

Proximity to overhead electrical conductors.

Is the lift to be made over workmen or a public thoroughfare, if so what precautions have to or are to be taken?

What are the dimensions of the load to be lifted?

What is the mass of the load to be lifted?

What is the lift height?

Where is the load to be placed?

Are proper slings and other lifting tackle available?

Is a certified dogman available?
