WorkSafe Victoria Industry standard / Safe erection of structural steel for buildings 5
1. Introduction
1.1 Purpose
Under the Occupational Health and Safety
Act 2004 employers have a general duty to
ensure the health and safety of employees at
work. Employers involved in construction work
also have specific duties under the construction
part of the OHS regulations to control any
risk associated with construction work as far
as reasonably practicable.
This industry standard provides practical guidance
for the design, fabrication, transportation and
erection of steel members for buildings, to
eliminate or reduce the risk to the health and
safety of:
• employees and contractors involved in
structural steel erection
• the public in the vicinity.
The main hazards risking the health and safety of
workers in structural steel erection are:
• falls from heights
• falling objects
• collapse of the structure
• plant used in the work.
1.2 Scope
This industry standard applies to the
construction of:
• portal framed buildings
• residential and other buildings where steel
frames provide structural strength and stability
to the whole building.
Generally, the structural steel members
covered include:
• portal and other frames
• columns, beams, rafters, purlins, girts
and bracings.
The industry standard does not apply to the
construction of:
• buildings that have steel members such as
lintels, posts or frames that are not part of the
complete steel structure providing stability
• light-gauge, cold-formed metal stud wall, floor
and roof systems for structures such as villa
housing and those homes, garages and sheds
which come in a “kit” style.
Parties, who are excluded in the list above, are
encouraged to use this industry standard,
regardless, as a guide for the safe erection of
their steel framed structures.

1. Introduction
1.3 What is the status of this
industry standard?
The guidance in this industry standard should be
followed. An alternative method may be followed
if it will achieve an equivalent or better level of
health and safety.
Where this industry standard reflects the OHS
Act and OHS Regulations (including the
construction regulations), this is indicated by the
use of the word “must”. In such cases, this
guidance must be followed.
Steel structures should be designed in
accordance with the key Australian standards
dealing with the design, fabrication and erection
of steel structures:
AS 3828:1998, Guidelines for the erection of
building steelwork
AS 4100:1998, Steel structures.
These documents, and other relevant Australian
standards, provide detailed technical guidance.
Where any technical conflict arises between a
provision of this industry standard and a technical
provision of the Australian standard, the
Australian standard provision should be followed.
However, where the guidance in this industry
standard reflects a legal requirement in Victoria,
this industry standard should be followed.
See Appendix 1 for a list of relevant Australian
standards and other guidance information.
1.4 How to read this
industry standard
This standard deals separately with each stage
of structural steelwork in sequence. Section 2
provides an overview of the key roles in the
whole process for safe erection of structural
steel, their responsibilities and methods of work
to ensure an efficient, co-operative and safe
working environment.
The sections that deal with the stages in the
process are:
Section 3: Design
Section 4: Fabrication
Section 5: Transportation
Section 6: Erection.
Each of these sections describes the key
responsibilities of that stage in the process, and
provides a table of common hazards and risk
control measures.

2. Overview
2.1 Management and control
Erecting structural steelwork for building construction takes place in a dynamic, changing environment
where there are many hazards and risks.
Proper and timely planning and coordination are the most effective ways to manage those hazards
and risks.
Projects involving structural steel construction have four main stages (dealt with in sections 3 to 6)
where risks to health and safety need to be considered:
• design
• fabrication
• transport
• erection.
The parties with roles and responsibilities at the various stages of projects are:
Structural
design engineer
The engineer, with experience in structural steel, who is responsible for the
engineering design of the overall building.
Builder The party responsible for project managing the construction of the building
and who has control of the building site.
Erection
engineer
The engineer who is responsible for the engineering design and stability
aspects of the erection of the steel structure. This role requires the person to
have a sound knowledge of the structure and its capacity in a temporary state.
Fabricator The party responsible for making the steelwork.
Shop detailer Engaged (usually by the fabricator) to produce the shop drawings.
Transporter The person who delivers the steel to the building site.
Erector The employer responsible for engaging the erection crew and erecting
the structure.
Note: On some projects, one person may perform more than one role, or parts of different roles.
This industry standard assumes that each role is carried out by a different person.

2. Overview
Diagram 1: Functional representation of the key roles (outlined in 2.1)
Note: There may be variations to this flow chart.
Client Architect
Structural design engineer
• produces the structural design of the building
• reviews the shop drawings (produced by the shop detailer and fabricator)
Builder
• project manages the construction of the building
• controls the site
• ensures contractors develop and implement relevant safe work practices
• monitors and liaises with key parties at each stage
Erection engineer
• approves the sequential erection procedure and prepares associated
erection designs
• approves the stability of the structure during construction as and when required
Fabricator
• manufactures the steel members
• engages the shop detailer
Shop detailer
• develops shop drawings for
fabricator, that are signed off by
the erection engineer Transporter
• transports the steel members from the
fabricator to the site
• obtains authorised planned routes and all
necessary permits
Erector
• develops the sequential erection procedure
• engages and briefs the erection crew
• ensures stability of all stages in consultation
with erection engineer
• produces the SWMS and discusses with the
erection crew and relevant parties

2. Overview
The functional relationship between each party is
outlined in Diagram 1, on the previous page.
Each party is responsible for the matters that are
under its management and control. Managing
risks arising from these matters is more effective
when parties regularly consult one another and
review how the next part of the process
will proceed.
For example, close co-operation between all
parties is essential to ensure that the procedure
for the erection of steel work is safe. They should:
• ensure the procedure is acceptable to all
parties and signed off by the erection engineer
• review the procedure before activities begin.
2.2 Health and safety
representatives
Planning and coordination must involve
consultation with those engaged in the work and
the health and safety representatives (if any).
A health and safety representative (HSR) is
elected by the workers to represent their health
and safety issues at work. HSRs must be
consulted alongside employees and contractors
on issues relating to health and safety, including
when processes are reviewed.
For further information, see publication, Employee
Representation.
2.3 Key planning tools
There are six key documents which help ensure
safe work in structural steel erection. These are:
• construction drawings – architectural
and structural
• shop drawings – drawn up by the shop
detailer, who is engaged by the fabricator, in
consultation with the erection engineer, and
detail what steel members are to be
manufactured. Shop drawings are reviewed by
the structural design engineer before
fabrication (see Section 4 – Fabrication)
• marking plans – developed by the fabricator
and detail where steel members will be
positioned in the erection process (see
Section 6 – Erection)
• sequential erection procedure – usually
developed by the erector and approved by the
erection engineer. The sequential erection
procedure sets out the steps for the work in
the correct order of erection (see Section 6 –
Erection)
• safe work method statement (SWMS) –
developed by the erector in consultation with
the crew and the builder, and identifies the
hazards and risk controls for each step of the
erection sequence (see Section 6.3.3, as well
as Appendix 1 for an example)
• erection design – developed by the erection
engineer based on the sequential erection
procedures prepared by the erector.
The responsibility for completing and endorsing
these documents in each stage is discussed in
the relevant stage sections.
2.4 Licences for high risk work
The erection of structural steel is “high risk work”,
involving the operation of a variety of plant and
the use of certain skills. Those workers operating
cranes and other particular plant must have the
appropriate licence before anyone can perform
high risk work (see Table 1).
Anyone who is being trained, in order to obtain a
licence, must be directly supervised if operating
the relevant equipment or carrying out specific
works without a licence, to ensure that the work
is carried out safely.
The arrangements for issuing licences to
operators of industrial equipment are set out in
the OHS Regulations 2007.

2. Overview
Table 1: Licences required for high risk work used in steel erection
Licence code High risk work
LF Forklift truck operation
DG Dogging
A licence is required if:
• there is a need to apply slinging techniques that require judgement to be exercised
• there is a need to direct a crane or hoist operator in the movement of a load when the
load is out of the operator’s view.
RB Basic rigging
Work involving:
• movement of plant and equipment
• steel erection
• particular hoists
• placement of pre-cast concrete
• safety nets and static lines
• mast climbers
• perimeter safety screens and shutters
• cantilevered crane loading platforms.
RI Intermediate rigging
In addition to the work associated with basic rigging, this work involves the rigging of:
• cranes, conveyors, dredges and excavators
• all hoists
• tilt slabs
• demolition
• dual lifts.
RA Advanced rigging
In addition to the work associated with intermediate rigging, this work involves:
• the rigging of gin poles and sheerlegs
• flying foxes and cableways
• guyed derricks and structures
• suspended scaffolds and fabricated hung scaffolds.

2. Overview
CT Tower crane operation
CN Non-slewing mobile crane operation (greater than 3 tonnes)
CV Vehicle loading, crane operation (greater than 10 metre tons; the operation of crane
trucks will usually be limited to the delivery of steel members to site)
C2 Slewing mobile crane operation (up to 20 tonnes)
C0 Slewing mobile crane operation (over 100 tonnes)
WP Boom-type elevating work platform operation (boom length greater than 11 metres)
2.5 Competency and training
In addition to the licences listed above, employers must also ensure that their employees
have completed:
• construction induction training (such as a ‘construction induction card’ or equivalent)
• training in the use of plant that does not require a licence for high risk work to operate – for
example, a boom-type elevating work platform (boom length 11 metres or less), telehandler or
non-slewing mobile crane less than 3 tonnes
• a site-specific induction
• training on how to work in accordance with the SWMS developed for the task
• training on how to eliminate or control specific hazards and risks involved in the work which are not
covered by an SWMS, for example, manual handling and UV-protection.
Where relevant, training for harnessed-based work positioning and fall protection systems may also
be required.

3. Design stage
3.1 General
There are two separate phases of design in
structural steel erection:
i) Structural design
The first phase involves the structural design of
the building, for in-service condition, which is
carried out by the structural design engineer.
The structural steel design should be produced
according to AS 4100, Steel structures and AS
3828, Guidelines for the erection of building
steelwork, which detail how risks can be
eliminated or reduced in the design stage. Any
associated concrete design, such as building
foundations, should comply with AS 3600
Concrete Structures.
ii) Erection
The second phase, the design for erection, is for
the handling, transportation and erection of the
individual members and structure. It may be
produced independently of the structural design
of the building.
Ideally, planning for the safe erection of structural
steel work should be considered at the design
stage. Structural design engineers should
consider the safe working conditions for those
involved in the erection stage, and eliminate as
many of the hazards as possible at this stage.
3.2 Roles during the design stage
The structural design engineer is responsible for
the structural design of the building.
3.3 Managing risk at the
design stage
Failure to plan and design for safety, from the
outset, can result in unsafe practices onsite and
in structural instability during erection. Accidents
in the erection of structural steelwork are not
restricted to falls. They can also occur because of
structural instability during erection, and while
handling, lifting and transporting material.
The stability of the building should be checked by
the erection engineer at agreed times with the
builder during erection.
Special care should be taken in design and during
construction to guard against progressive
collapse. Progressive collapse means a
continuous sequence of failures initiated by the
local failure of one part of the structure.
Progressive collapse may be prevented by providing:
• adequate structural strength and continuity of
the structure and its parts, or
• temporary bracing, shoring or ties, or
• alternative load paths that cause applied forces
to be safely transmitted through the structure
The failure of a single member should not lead to
the complete collapse of the structure. This is

3. Design stage
particularly important where structural stability is provided by steel roof and wall bracing systems. In
addition, consideration should be given to the effects of abnormal loads on the building, such as gas
explosions or vehicle impacts.
• As part of the structural design process the structural design engineer must provide sufficient
details to allow the shop detailer to prepare shop drawings and the erection engineer to prepare the
erection design
• The shop drawings and erection design should be submitted to the structural design engineer for
review to ensure that they comply with the requirements of the structural design
• Before the shop drawings are produced, the parties involved in the design, fabrication, transport
and erection process should liaise to plan the complete construction and erection sequence.
The following table lists what hazards may arise if the design does not adequately provide for safety in
the erection of the structure. Methods for managing and controlling the risk of hazards are also provided.
Common
hazards
• The ‘buildability’ of the design
• Collapse of structure due to member failure from temporary loading
during erection
• Members not designed for transportation
Risk
controls
The structural design engineer is required to provide design drawings
which include:
• date and issue number of the drawing
• plans and elevations clearly indicating the structural framing and layout
• structurally critical dimensions (unless supplied on the architectural drawings)
• make provision for positive connections between members of the structure that
have been specified to resist imposed lateral and vertical force
• the grade of steel members
• reinforcement required for in-service loads and temporary conditions
• levelling pad details
• structural design criteria affecting construction
• purlin and frame details
• framing connection locations and required type approval
• Consideration should be given to details such as:
– site limitations
– local street access
– delivery sequence
– transport requirements
– overhead obstructions.
These aspects can have a significant effect on the size of steel members and on
the erection process.

4. Fabrication
stage
4.1 General
In consultation with the erection engineer, the
shop detailer produces the shop drawings, and
the fabricator works from these drawings to
produce the steel members.
The structural design engineer should ensure that
the shop drawings comply with the structural
design. The drawings are reviewed by the
structural design engineer before fabrication of
the steel members.
4.2 Roles during the
fabrication stage
The fabricator is responsible for the accurate
detailing and fabrication of the steelwork to
ensure members fit together correctly. Detailing
should include the ease of making connections
on site.

4. Fabrication stage
4.3 Managing risk at the fabrication stage
Common
hazards
• Incomplete or inaccurate shop drawings
• Collapse of structure due to element failure
• Members not clearly marked or identifiable
• Weld failure due to poor quality or lack of testing
• Incomplete fabrication (missing components)
• Fabrication errors (angles, etc).
Risk
controls
The fabricator must:
• ensure strength of members by using grades of steel which are in accordance
with the relevant Australian standards
• ensure shop drawings comply with structural design drawings and include the
following information:
– the date and issue number
– the project location
– the structural design criteria affecting construction
– plans and elevations indicating the structural framing, layout and orientation
– clear identification and numbering of members
– structurally critical dimensions
– where appropriate, the tolerance limits on the element
– the specifications and location of bracing or temporary supports
– the requirements and locations for framing connections
– the requirement for concrete foundations and base connections
– the requirements for lifting and location of any lifting points
– rigging details (for components that cannot be conventionally slung)
– ensure components are manufactured in accordance with design specifications
– ensure weld tests as per requirements
– design approval by the structural design engineer.

5. Transportation
stage
5.1 General
Workers can be exposed to the risk of injury
when loading, transporting and unloading steel
from transport vehicles. Delivery of steel onto the
site requires co-operation between the fabricator,
builder, transporter and erector so that the steel is
delivered in a timely and efficient manner, and
that it does not overload the delivery area or the
construction zone.
5.2 Roles during the
transportation stage
The transporter should have planned the routes
and obtained all necessary permits and
authorisation — for oversize or wide loads,
restricted routes, etc.
The transporter should be familiar with the
builder’s traffic management plan that includes,
where necessary, traffic controllers, barricades
and road closure permits to allow unimpeded
access to the site.
The builder should also provide a safe and
adequate unloading and lay-down area on the site
and ensure that the transporter has detailed
instructions on how to enter the site.
For information on the restraint of steel loads for
safety during transportation, see the VicRoads
publication A Guide to Restraining Steel.
For information on traffic management see the
VicRoads Code of Practice for Worksite Safety –
Traffic Management and AS 1742.3, Manual of
uniform traffic control devices, Part 3: Traffic
control devices for works on roads.
5.3 Managing risk at the transportation stage
Common
hazards
• Steel falling from slung loads while unloading
• Steel falling because the vehicle load is unstable or becomes
unstable during unloading
• Vehicle becoming unstable
• Vehicle collapsing into a hole (if the site isn’t adequately compacted)
• Lack of set-up space
• Lack of traffic management plan
• Access/egress: steep grade and short pitch
• Vehicle collision
• Worker falling from vehicle during loading and unloading.

5. Transportation stage
Risk
controls
Before loading vehicle
The Fabricator should check that:
• the sequence of loading is agreed between the fabricator and the builder
• each member is clearly marked (together with its mass where it is over
1.5 tonnes) before loading.
The Transporter should check that:
• trucks have restraining spikes in place
• steel is supported and secured, so that there is no uncontrolled movement
of the steel until it is ready to lift
• sufficient hardwood bearers, or equivalent, have been provided for loading.
The Builder should check that:
• the sequence of loading is agreed between the builder and the erector
• a crane of the required type and capacity is at the site
• the area for unloading is firm and level and checked for load capacity and
where applicable or necessary, ground computations
• there is an adequate set-up area
• there is a traffic management plan
• the grade and pitch of access/egress is suitable and safe for the vehicles
and their loads.
When loading the vehicle
• the vehicle and load is stable and load will remain stable during unloading.
On vehicle’s arrival at site
• securing chains or straps are not removed until restraining spikes in place
• the steel has not shifted into a dangerous position
• the vehicle is positioned as directed by the erector and stabilised before the
steel restraints are released
• if the unloading sequence can lead to the instability of loads, the steel is
individually restrained and the loading configuration checked so that
unloading does not result in the load or the vehicle becoming unstable
• the vehicle is not moved without the steel being properly secured.
The Erector should check that:
• loads are lifted in a level manner
• loads are not lifted vertically or at a slope
• loads are sufficiently secured to prevent inside lengths from falling out if the
bundle is at an angle
• there is fall protection for workers and doggers on the truck.

6. Erection stage
6.1 General
Safe erection of structural steel work depends on
proper and timely planning. All personnel should
be aware that erection of any structural steel is
potentially hazardous and that planning must
control any risk from these hazards.
6.2 Roles in the erection stage
6.2.1 Builder
The builder has overall management and control
of the building site and should ensure that:
• the building construction is in accordance with
the project schedule
• a traffic management plan is developed and
implemented (which includes safe access /
egress points and delivery areas)
• a marking plan has been submitted
• a delivery schedule submitted by the fabricator
is agreed upon
• the activities of all contractors are being
coordinated and supervised
• the ground surface or supporting structure is
suitable for plant (such as EWP, mobile
scaffolds and cranes) to operate safely
• holding-down bolts, cast in concrete footing,
pedestals or slabs, are within tolerance
• shop drawings (prepared by the shop detailer)
have a signed statement from the structural
design engineer that the shop drawings comply
with the structural design
• the erection engineer provides clear advice on
how to achieve stability for each stage of the
structure’s erection
• weather conditions are continually monitored,
particularly potentially hazardous situations like
high or strong winds and electrical storms, and
that a contingency plan has been developed for
severe weather
• at least one of the erection crew or another
person who remains on site throughout
erection should hold a current qualification as a
Level 2 first aider
• a safe work method statement has been
developed and work is undertaken in
accordance with the SWMS.
These tasks are also contained in a checklist.
See Appendix 2 – Builder’s checklist.
The builder must also provide to contractors a
detailed site plan, which includes information on:
• site location
• access points
• structure location
• suitable ground bearing locations
for crane operations
• uploading areas
• storage areas.

6. Erection stage
The builder should ensure that the accuracy of
each contractor’s work is within the tolerance of
the level or position nominated by the erection
engineer or relevant standard. Any modifications
to the building layout also need to be checked by
the builder for approval by the erection engineer.
As principal contractor, the builder prepares the
Health and Safety Coordination Plan according to
section 5.1.16 of the Occupational Health and
Safety Regulations 2007 see handbook Working
safely in the general construction industry.
6.2.2 Erection engineer
The erection engineer approves the sequential
erection procedure which includes how the
structure is stabilised at each stage and signs any
modifications, and is required to provide guidance
to the builder and erection crew on
matters including:
• joints and additional erection cleats
• structural design criteria affecting construction
• temporary bracing
• lifting points
• loads and conditions likely to be experienced
during the lifting and erection
• any wind load limitations on the integrity of the
structure as it is being erected according to the
signed-off sequential erection procedure
• wind load on the braced members.
• joint positions (as they affect erection sequences)
• accessibility of connections
• fixings for working platforms, hand rails etc
• preferred method of connecting steel members
• preferred type and number of cranes to erect
members of particular size and shape, and for
vertical and horizontal bracing requirements
• instructions on how to stabilise the structure at
each stage of erection which involves:
– verifying the adequacy of the base
connections (steel to foundations)
– checking stability under construction
load conditions
• capacity to withstand accidental vehicle impact.
The fabricator can also provide guidance in
this area.
6.2.3 Erector
The erector ensures that:
• the structure is erected in accordance with the
sequential erection procedure
• an SWMS is developed in consultation with the
erection crew (see the sample SWMS in
Appendix 1)
• work proceeds in accordance with the SWMS
• confirms with the builder’s representative that
the ground or supporting surface is suitable for
mobile plant to safely operate
• pre-assembly of members and the movement
and location of heavy members are considered
prior to installation
• weather conditions are continually monitored,
and in particular, potentially hazardous
situations like high or strong winds and
electrical storms for which a contingency plan
should be developed and implemented
as required.
These tasks are also contained in a checklist.
See Appendix 3 – Erector’s checklist.
6.2.4 Erection crew
An erection crew consists of:
• an experienced structural steel supervisor
• riggers
• doggers
• crane operator.

6. Erection stage
The erection supervisor is responsible for
directing and coordinating the agreed sequential
erection procedure (see 6.3.1). They should hold a
high risk work licence for rigging in either the
Intermediate Rigging or Advanced Rigging
classes (class codes RI or RA) as appropriate
(see Table 1).
The crane operator must hold a licence to perform
high risk work appropriate for the type of crane and,
in the case of a slewing mobile crane, the crane’s
capacity (WLL) (or be under the direct supervision
of the holder of the appropriate licence).
The size and make-up of the remainder of the
erection crew will vary depending upon the nature
of the site and the particular circumstances. All
members of the crew must hold the basic rigging
licence (class code RB) as a minimum. Anyone
who is being trained, in order to obtain a licence,
must be directly supervised to ensure that the
work is carried out safely.
6.3 Documentation in the
erection stage
6.3.1 Sequential erection procedure
The erector, in consultation with the builder,
erection engineer and other parties involved in
the work, needs to plan the process for lifting and
erecting individual members.
The process is set out in the sequential erection
procedure which is used by the erection crew.
The erector is responsible for ensuring that a
sequential erection procedure is in place and that
it has been approved by the erection engineer.
The sequential erection procedure includes:
• site limitations
• member sizes
• access for positioning and lifting of members
• crane size, mobility and access, and use of
other large plant
• the erection sequence
• the stability requirements of the structure at all
stages during erection
• requirements for working at height
• overhead obstructions, including overhead
power lines
• weather restrictions
• specialty bolting or site welding requirements,
included on the marking plan.
6.3.2 Marking plan
The marking plan shows the erector where each
member will be placed on the site. It is prepared
by the shop detailer for the fabricator, and
approved by the structural design engineer.
The marking plan includes:
• location of each element
• configuration of braces and any temporary
bracing/supports
• clear markings to identify each member.
6.3.3 Safe work method statement
Any erection of structural steel will require a site
specific SWMS (see Appendix 1). The SWMS must
list the high risk construction work, as a minimum,
and describe how the risks are to be controlled.
The SWMS is prepared by the erector in
consultation with the erection crew and reviewed
by the builder.
High risk construction work in steel erection
may include:
• a risk of falling more than two metres
• structural alterations that may require
temporary support to prevent collapse
• working near live power lines
• tilt-up or precast concrete (which may be part
of the project).

6. Erection stage
• working on or adjacent to roadways or railways used by road or rail traffic
• any movement of powered mobile plant, for example, the use of EWPs.
This particular information must be identified and provided by the builder to the person preparing the
SWMS. The SWMS should also identify any other hazards associated with the work and state the
measures necessary to control them. For more information, see handbook Working safely in the
general construction industry – A handbook for the construction regulations.
6.4 Managing risk at the erection stage
The key risks involved in steel erection, and the controls for each of these are outlined below.
Common
hazards
1 Falling from a height while rigging
2 Falling objects
3 Collapse of the structure during construction
4 Being struck by plant
5 Plant contacting underground or overhead utility services
6 Being struck by objects such as steel members

controls
1 The erector should reduce the need for work at height by:
• constructing as much of the steelwork as possible (such as modules or frames)
at ground level, or from erected floor slabs or decks in the structure, and
• where reasonably practicable, releasing the lifting sling or device from ground
level by the use of long slings, remote release shackles or other suitable devices.
The erector should prevent the risk of a fall of a person working at a height by
using in order of effectiveness:
• passive fall prevention devices, for example, work platforms and EWPs
• work-positioning systems such as travel-restraint systems and industrial
rope-access systems, and/or
• fall arrest systems such as catch platforms and safety-harness systems.
For further information, see the Compliance Code for the Prevention of Falls in
General Construction.
2 The erector should reduce the risk from falling objects by:
• restricting access when there is overhead work by establishing, where
practicable, exclusion zones
• preventing, where practicable, loads being lifted or transported over people
or amenities
• ensuring only rigger/dogman slings loads and, where appropriate, fix tag lines
• using lifting beams to position members where necessary to ensure the stability
of the member

6. Erection stage
Risk
controls
• considering perimeter screens, guardrails with integral toe-boards and wire
mesh, debris nets, cantilever work platforms, scaffolding sheathed with protective
material and/or lanyards to secure tools and equipment
• using materials boxes which are fully sheeted to enclose the load
• ensuring safety helmets are worn at all times.
3 a) Before erection, to avoid collapse, the erector should:
• ensure a sequential erection procedure is prepared, which has been approved by
the erection engineer and is consistent with the marking plans
• ensure that an experienced steel erection supervisor is present at all times to
oversee the implementation of the sequential erection procedure
• ensure an adequate exclusion zone to prevent risk to other people not involved in
the erection
• only start the erection of a member or sub-assembly when equipment to ensure
the structure’s stability is available and being used
• ensure temporary guys or bracing are securely anchored
• place adequate visual barriers between guys and plant/vehicle movement areas.
b) During erection, to avoid collapse, the erection supervisor must:
• verify the stability of the structure in accordance with the erection engineer’s
specifications:
– at the end of each work day
– when fastenings may be incomplete
– during strong winds or when strong winds are forecast
• seek approval from the builder (or erection engineer where appropriate) to cease
work at unscheduled points where the structure has not been completed to the
specifications of the erection engineer’s design
• Obtain, from the builder, the erection engineer’s written approval before loads are
placed onto the structure
• where possible, start erection in a nominated braced bay (if this is not possible,
make sure that the erection engineer is involved in developing an alternative
site-specific sequential erection procedure)
• check the fittings for the support of columns during erection, to ensure adequate
structural capacity for the erection conditions
• make sure that all beams are secured before releasing the slings
• make sure that all bolted connections are effective to ensure the stability of the
steel structure.
4 To avoid being struck by plant and before the use of a crane or any other
powered mobile equipment, the erector should consider:
• crane selection, access and siting in accordance with AS 2550 Parts 1, 4 and 5
(cranes, hoists and winches)
• protection of the public

6. Erection stage
Risk
controls
• the location of any excavations or underground services that may affect
a crane load
• the proximity of overhead power lines
• the capacity of the ground or supporting surface to bear the load
• check the type and amount of packing required under the crane’s outriggers to
support the proposed loads
• written procedures for setting up and dismantling of the crane and the
lifting method
• the composition of the rigging crew suits the job
• procedures for visual and audible signals between the crane operator and the
erection crew
• ground support conditions
• selection of lifting gear
• emergency procedures
• prevailing or forecast weather conditions
• the need to avoid lifting loads over people.
The use, of two or more cranes to move and position loads, is hazardous and
should be avoided if a single crane is capable of doing the job. Where it is
necessary to use two cranes to «dual lift» members, the following controls are to be
implemented:
• the weight of the load and its centre of gravity as well as the weight of the lifting
gear must be carefully calculated.
• cranes of similar characteristics should be selected.
• the position of each crane should minimise movement and slewing.
• the lifting capacity of each crane must be 20% greater than the share of
the load.
For further advice on multiple crane lifting, see A Guide to Rigging, chapter 18.
5 a) Where plant is working near overhead lines, the erector should:
• identify all powerlines services before permitting any crane or other mobile
plant on site
• check that material and plant is moved or operated outside the “No Go Zone” of
3000 mm from an overhead electrical cable on a pole or 8000 mm if the
electricity cable is on a tower line (If erecting scaffolding, the “No Go Zone”
during this process is 4.6m distant and 5m below from the nearest power line)
• if work or plant is able to encroach on this clearance, the erector must obtain
permission from the electricity company or develop a SWMS and work in
accordance with it.
Note: Tiger battens do not protect from risk of electrocution or electric shock.
They provide a visual warning only.

6. Erection stage
Risk
controls
b) When plant is working near underground services, the erector should:
• ensure that, unless permission has been obtained from the utility company, work
is not carried out closer to the services than:
• 3 metres in the case of an underground asset registered under the Pipelines
Act or an electricity cable with an in-service voltage greater than 66 kV, or
• in the case of other services, 500 mm for plant and equipment and 300 mm
for individuals.
6.5 Other hazards
Consideration should be given to other hazards associated with steel work. Any risks posed by these
hazards must be controlled. They may include:
• noise
• manual handling
• hot work
• exposure to hazardous substances
• dangerous goods
• electrical work
• sun (UV) exposure.

• Not following the
sequential erection
procedure
• The sequential erection procedures must be followed
unless authorisation has been approved by both the
builder and the erection engineer
• Steel frame to be inspected daily for stability and
results documented
• Electrical hazards • Do not use electrical equipment that does not have a
current tag
• Keep leads elevated or adequately protected and away
from sharp edges and water hazards

load too soon
• The riggers and doggers are the only people permitted to
release the load
• Load is only to be released when adequately fixed
and supported.
• Loading incomplete
bays with panels
and roofing
• Check that the erection engineer has approved
placement load
• Check that the placement load is within constraints
• Check that columns have been grouted prior to loading.

Appendix 1
Please ensure you have completed this SWMS correctly by checking the following.
I have completed the form with the following information:
I have discussed with relevant employees, contractors and HSRs – what work will be high risk, the tasks
involved, and associated hazards, risks and controls.
I have listed, in the first column ‘What are the tasks involved?’ – the main stages for the tasks involved.
I have listed, in the second column ‘What are the hazards and risks?’ – the hazards and risks for each work
task under the relevant stage of construction.
I have listed, in the third column ‘How will the hazards and risks be controlled?’ – control measures for the
hazards and risks, based on the hierarchy of control levels 1 to 4 (listed below). I have chosen a control
measure (and how it is to be used) that is as close to level 1 as is reasonably practicable.
Control levels 1 to 4:
1. Eliminate risk to health or safety associated with construction work.
2. Reduce risk to health or safety by any one or any combination of the following:
• substituting a new activity, procedure, plant, process or substance
• isolating people from the hazard, such as barricading, fencing or guardrailing, or
• using engineering controls, such as mechanical or electrical devices.
3. Use administrative controls, such as changing the way the work is done.
4. Provide appropriate personal protective equipment (PPE).
The crew has been inducted to this SWMS, and briefed to stop work immediately if the SWMS
is not being followed.
I will monitor the work and, if controls are not adequate, I will stop the work, review the SWMS,
adjust it as required and re-brief the team.
I will retain this SWMS, and its amended form if applicable, for the duration of the project.
