Health and safety obligations can overlap in a contracting chain, where contractors and subcontractors provide services to a lead contractor or client.
These guidelines are for persons conducting a business or undertaking (PCBUs) who are sharing a workplace with other businesses, or are working as part of a contracting chain. They provide advice on how you can meet your duties under the Health and Safety at Work Act 2015 (HSWA), illustrate different contractual relationships between parties, and provide examples of ways you can build health and safety into contract management.
- You must consult, cooperate and coordinate with other PCBUs when working in a shared workplace, or as part of a contracting chain.
- You can’t contract out of health and safety duties.
- You should always build health and safety into contract management.
1.0 Understanding your duties under HSWA
PCBUs must consult, cooperate and coordinate with other PCBUs when they are working in a shared workplace or working as part of a contracting chain.
1.1 What this guide is about
The Health and Safety at Work Act 2015 (HSWA) is the key work health and safety law in New Zealand. A guiding principle of HSWA is that workers and other persons should be given the highest level of protection against harm to their health, safety, and welfare from work risks so far as is reasonably practicable.
Contracting is when a PCBU1 (the contracting PCBU) hires someone else (the contractor – also a PCBU) to carry out temporary work under contract.
Contractors may be individuals or businesses. Contractors, their subcontractors, and their employees are classed as the workers of the lead contracting PCBU.
Contract types may include:
- projects (such as construction, installation or upgrade work)
- maintenance and repair activities
- service and cleaning contracts.
PCBUs that work together will often share health and safety duties in relation to the same matter. These are called overlapping duties. PCBUs have a duty to consult, cooperate with and coordinate activities with all other PCBUs they share overlapping duties with, so far as is reasonably practicable.
This guide explains:
- Section 1: How PCBUs can work together to meet shared duties
- Section 2: How to build health and safety into contracting tendering practices.
This guide is for all PCBUs who share overlapping duties with other PCBUs, either in a shared workplace or as part of a contracting chain.
While this guide focusses mainly on contracts that are awarded by tender, the information can be applied to other contracting situations.
1.2 What you need to know before reading this guide
If you share duties with other PCBUs, what must you do?
You must consult, cooperate with and coordinate activities with all other PCBUs you share duties with, so far as is reasonably practicable.
Where duties are shared, all PCBUs have a responsibility to meet those duties, to the extent that they have the ability to influence or control the matter.
If you’re self-employed
If a self-employed person is working for another PCBU (for example, a self- employed welder who is contracted by a labour hire company), they both share duties as a PCBU. If the self-employed person decides how their own work is done and creates and controls risks, they are considered to have the ability to influence or control the matter. However, if a self-employed person is working for another PCBU, and the PCBU decides what they do, and how and when they do it, then that PCBU is considered to have the ability to influence or control the matter.
How can you work out if you share health and safety duties with other PCBUs?
PCBUs that work together, either in a shared workplace or in a contracting chain, will often share health and safety duties in relation to the same matter.
This is where several different contractors are working in the same place, such as a construction site, shopping centre or port. They will not usually share contractual relationships with each other. More than one contractor may control or influence the work onsite.
Example: A concert venue is an example of a shared workplace. There are usually multiple PCBUs, including contractors and subcontractors, working at the venue before, during and after a concert. Although the PCBUs carry out different jobs, they all share health and safety duties.
This is where several different contractors are all working together on the same project, although not necessarily in the same workplace. Usually, one PCBU will have the most influence and control over the work. These contractors need to enter into reasonable arrangements with each other to make sure that everyone’s health and safety duties are met.
Example: A Hawkes Bay winemaker contracts a harvesting company to harvest grapes from a Blenheim-based vineyard and transport them to the winemaker’s Hawkes Bay plant. The harvesting company sub-contracts a trucking company to pick up the grapes once they are harvested and transport them to the Hawkes Bay plant.
Even though the winemaker, the harvesting company and the trucking company don’t share the same workplace, they still have to work together to meet all their health and safety duties.
Examples of possible common shared duties are listed in Table 1.
|What is the duty?||What is the requirement?|
Primary duty of PCBUs
Health and Safety at Work Act 2015
You must ensure, so far as is reasonably practicable, that the health and safety of workers and other people are not put at risk by your work. This is called the ‘primary duty of care’.
This means ensuring, so far as is reasonably practicable:
For the other duties – see our guidance: Introduction to the Health and Safety at Work Act 2015
Health and Safety at Work Act 2015
You must, so far as is reasonably practicable, eliminate risks that arise from your work. If the risk cannot be eliminated, you must minimise it, so far as is reasonably practicable.
You must comply to the extent to which you have, or would reasonably be expected to have, the ability to influence and control the matter to which the risk relates.
For more information on managing risk, see our guidance: Identifying, assessing and managing work risks
Worker engagement, participation and representation
Health and Safety at Work Act 2015
You must ensure, so far as is reasonably practicable, that workers can raise concerns and express their views on work health and safety matters and that those views are taken into account.
You must also have practices that provide reasonable opportunities for workers to participate effectively in improving work health and safety on an ongoing basis.
For more information on worker engagement, participation and representation, see our guidance: Worker engagement, participation and representation
Section 56Health and Safety at Work Act 2015
If a notifiable event occurs, you must notify us as soon as you become aware of the event.
For more information on the notification duty, see our website: Notifiable Event
Health and Safety at Work General Risk and Workplace Management Regulations 2016
You must ensure that your workers have access to adequate first aid equipment, facilities for the administration of first aid and trained first aiders. If you share a workplace with other PCBUs, you can coordinate sharing first aid resources with them.
For more information on first aid requirements, see our guidance: Workplace first aid
Emergency plansHealth and Safety at Work General Risk and Workplace Management Regulations 2016
You have a duty to prepare, maintain and implement an emergency plan at your work. You must consult, cooperate and coordinate with other PCBUs that you share overlapping duties with to coordinate emergency procedures.
For more information, see our guidance: Emergency plans
Table 1: Common shared duties
1.3 What we expect in contracting situations
There can be several different levels in a contracting situation; either in a shared workplace, or in a contracting chain. Figure 1 shows an example of how a contracting situation could look, including a lead PCBU, a lead contractor, contractors, subcontractors and their workers.
|Level in contracting chain||What we expect from this PCBU|
Example: The owners of a large mall that is being refurbished
Example: A project management company
The lead contractor will likely have the most influence and control over the workplace.
Contractor (working as a PCBU)
Example: A large welding company
Subcontractor (working as a PCBU)
Example: A self-employed welder
Table 2: What we expect from PCBUs
Example: Safe Smash, a famous rock band from the USA, is performing at a sports stadium in Wellington for one night only. There are multiple PCBUs (including contractors) working to ensure the concert runs smoothly, and they all share health and safety duties.
There are two lead PCBUs in this shared workplace situation: the event promoter (Music Masters) and the venue management (Extreme Venues Ltd).
Some of the PCBUs and contractors working to set up the concert include:
- Music Masters (Geoff is the manager)
- Extreme Venues Ltd (Julie is the manager)
- Best Snacks Daily (food – Jamal is the manager)
- Bright Lights (lighting – Susie is the manager)
- Beatz Sound Crew (sound – Wiremu is the manager)
- Super Clean Services (cleaning – Jack is the manager)
- Ultra Security Ltd (security – Tatiana is the manager)
- In A Row (temporary seating – Deepali is the manager)
Some of these PCBUs and contractors also have their own workers and subcontractors. Each PCBU has to work with the others to make sure everyone is meeting their health and safety duties.
1.4 Working with other PCBUs
We recommend that you make a record of any discussions you have, and agreements you reach around how work will be carried out.
There are four main points to remember about overlapping duties:
- You have a duty to consult, cooperate with and coordinate activities with all other PCBUs you share overlapping duties with, so far as is reasonably practicable.
- You can’t contract out of your health and safety duties, or push risk onto others in a contracting chain.
- You can enter into reasonable agreements with other PCBUs to make sure that everyone’s health and safety duties are met.
- The more influence and control your business has over a workplace or a health and safety matter, the more responsibility you are likely to have.
These points are explained in more detail below.
You must consult, cooperate and coordinate with other PCBUs
You must, so far as is reasonably practicable, consult, cooperate and coordinate with other PCBUs that you share health and safety duties with.
Consulting, cooperating and coordinating can avoid you unnecessarily duplicating each other’s efforts, and help prevent any gaps in managing health and safety risks.
Some ways that you can meet this duty and avoid gaps include (but aren’t limited to):
- planning ahead by thinking through every stage of the work
- thinking about how the work could affect other PCBUs and the public
- identifying the risks that need to be managed
- consulting with other PCBUs to agree on how those risks will be managed
- consulting with other PCBUs to decide who is best placed to manage each risk, and
- clearly defining roles, responsibilities and actions, so that everyone knows what to expect.
Example: First aid
Several different PCBUs, including contractors and their workers, are working at the sports stadium in Wellington to prepare for the Safe Smash rock concert. They are located in different parts of the stadium, and working on different jobs. All the PCBUs have a duty to ensure that workers and other people at the workplace have access to first aid facilities and equipment, as well as trained first aiders.
Extreme Venues Ltd nominates Julie to organise a meeting with the other PCBUs and contractors before any work starts, to discuss the best way to meet the first aid duty. All the PCBUs and contractors state that as well as fully equipped first aid kits, they all have at least one trained first aider in their teams who will be onsite every day. Julie is satisfied with this, but as a representative of a lead PCBU she decides to:
- check that the first aid qualifications of the workers are up-to-date
- make sure that the venue provides equipment for more serious injuries or illnesses, such as a defibrillator
- make sure that every morning at the daily activity briefing, the PCBUs discuss who the first aiders are for that day and how they can be contacted if needed.
This is an example of one PCBU consulting, cooperating and coordinating with other PCBUs, to ensure workers and other people at the workplace have access to first aid facilities, first aid equipment and trained first aiders.
Geoff (the representative for the event promoter Music Masters) and Wiremu (the representative for the sound company Beatz Sound Crew) are discussing the activities planned for the day, and any risks that the work may create. Wiremu tells Geoff there will be a sound check and workers may be exposed to loud noise levels. Geoff and Wiremu identify this as a risk, and agree to work together to eliminate or minimise this risk so far as is reasonably practicable.
Wiremu explains to Geoff that the sound check is compulsory, so the risk can’t be completely eliminated. To minimise the risk of hearing damage for workers and other people in the area, Geoff:
- asks Wiremu to carry out the sound check at lunch time, when most people have left the venue to have their lunch
- asks Wiremu to send warning announcements over the loudspeaker 15 minutes before, 5 minutes before and 1 minute before the sound check is carried out, so that workers have time to leave the immediate area if possible
- provides each of the contractors with a written notice of the time of the sound check the day before, so that they can ensure as many of their workers are off-site as possible at the time
- provides adequate hearing protection for any workers or other people that are unable to leave the immediate area when the sound check is carried out (having checked with Wiremu what the correct class of hearing protection to provide would be).
This is an example of one PCBU consulting, cooperating and coordinating with other PCBUs to minimise risks to health and safety, so far as is reasonably practicable.
Example: Worker engagement, participation and representation (WEPR)
PCBUs have a duty to, so far as is reasonably practicable, make sure that workers’ views on health and safety matters are asked for and taken into account. They must also have clear, effective and ongoing ways for workers to suggest improvements or raise concerns on a day-to-day basis. Multiple PCBUs, including contractors, are working to prepare the stadium for the concert, and it takes several days beforehand to get everything ready. Geoff and Julie (as representatives of the lead PCBUs) decide that every morning before the day’s work starts, they will hold a daily activity briefing with all the contractors working onsite that day. In this daily briefing, Geoff and Julie will discuss with contractors and workers:
- the work activity planned for that day
- health and safety risks and the best ways to manage these cooperatively
- which first aiders are onsite that day and how they can be contacted.
At the end of each daily activity briefing, all PCBUs, contractors and workers will agree on their actions for that day.
This is an example of all PCBUs consulting, cooperating and coordinating with other PCBUs to minimise risks to health and safety, so far as is reasonably practicable.
You can’t contract out of health and safety duties
If you are sharing a workplace with other PCBUs, or working together in a contracting chain, you are likely to share overlapping duties. Each PCBU in the contracting chain should be aware of overlaps and manage risks that are appropriate and reasonably practicable for them to control.
- contract out of your health and safety duties, or
- push risk down the contracting chain to another PCBU.
You are not only responsible for your own workers; your responsibility also extends to workers whose work you influence and direct, and other people at the workplace. This includes supporting those people to meet their health and safety duties, and not passing on or increasing risk through your arrangements with them.
We expect PCBUs at the top of a contracting chain to be leaders in encouraging good health and safety practices throughout the chain. We also expect them to use sound contract management processes.
These processes may include:
- choosing competent contractors
- exchanging information
- planning and monitoring carefully
- doing post-contract reviews.
Example: Hazardous substances
In preparation for the Safe Smash concert, Extreme Venues Ltd contracts Super Clean Services to clean the stadium and seating. The Extreme Venues Ltd representative, Julie, instructs Super Clean Services to use the cleaning agents that are stored in the stadium’s maintenance cupboard. However, she fails to pass on the instructions for usage of the chemicals to Jack (the representative from Super Clean Services), and Jack fails to follow this up with her. As a result, the workers from Super Clean Services don’t know they need to dilute the cleaning agents before using them. A worker is splashed with the cleaning agent while carrying out her work and develops a chemical burn.
When Jack reports this incident to Julie, she says that it was his responsibility to pass the usage instructions onto his workers, and that it was nothing to do with her. Extreme Venues Ltd attempts to push the risk down the chain to Super Clean Services. However, both Extreme Venues Ltd and Super Clean Services share the duty to protect the health and safety of workers and others. This includes ensuring the safe handling of substances.
Some things that Julie could have done to meet her duty include:
- Before awarding the contract to Super Clean, Julie should have checked that their workers were trained to use and handle the substances they would be using at the venue. She could have asked what sort of training they received, including the classes of substances they are trained to use.
- Asking workers if they were provided with personal protective equipment (PPE), and had access to appropriate first aid facilities.
- Providing the relevant information ahead of time, including safety data sheets.
- Checking the containers the hazardous substances were stored in were labelled correctly.
This is an example of both PCBUs failing to meet their duties, with the larger PCBU trying to push the blame onto a smaller PCBU.
You can enter reasonable agreements with other PCBUs
You can’t contract out of your health and safety duties. However, you can enter reasonable agreements with other PCBUs that you’re working with, to make sure everyone’s duties (including yours) are met. Usually, the PCBU who has the greatest ability to influence and control the work or workplace will have the most responsibility.
These agreements can be documented in contracts between the PCBUs. PCBUs must monitor each other, to make sure each PCBU continues to do what was agreed. WorkSafe may check that these arrangements are working well, and consider enforcement action if PCBUs are not meeting their health and safety duties.
Example: Notifying WorkSafe
Multiple PCBUs, including contractors, are preparing for the Safe Smash rock concert in Wellington. PCBUs have a duty to notify WorkSafe when:
- a death occurs as a result of work
- a notifiable illness or injury occurs as a result of work
- a notifiable incident occurs as a result of work.
Geoff (the representative from Music Masters) and Julie (the representative from Extreme Venues Ltd) hold a meeting with all the PCBUs involved in preparing for the concert, before the work begins. To make sure that the notification duty is met, they decide to nominate one PCBU to notify WorkSafe if a notifiable event happens. After consulting with each other, they all agree that Extreme Venues Ltd is the most appropriate PCBU to notify WorkSafe in the case of a notifiable event, because they have the most influence and control over the workplace. Extreme Venues Ltd would then inform the other PCBUs that a notification had been made to WorkSafe.
The other PCBUs should check with Extreme Venues Ltd, in the event of a notifiable event, that the notification has been made. If Extreme Venues Ltd has not notified WorkSafe within 48 hours, another PCBU should notify.
This is an example of several PCBUs entering a reasonable agreement with each other to ensure that the notification duty to us is fulfilled.
You must carry out your duties to the extent you have the ability to influence or control the matter
The extent of your responsibility to meet your health and safety duties will likely be different to other PCBUs you share duties with. This will depend on what ability they have to influence and control the health and safety matter.
The more influence and control you have over a health and safety matter, the more responsibility you are likely to have. There are three ways you can have influence and control over health and safety matters:
|Control over work activity||Control of the workplace||Control over workers|
|A PCBU in control of the work activity may be in the best position to control the health and safety risks.||A PCBU in control over the workplace, including plant and structures, has some influence and control over health and safety matters.||A PCBU has more influence and control over its own workers and contractors than those of another PCBU.|
Table 3: Ability to influence and control
The size of the PCBU, or its financial resources, does not automatically equate to its ability to influence and control health and safety matters. You need to consult, cooperate and coordinate with other PCBUs to make sure everyone is meeting their health and safety duties.
Example: Emergency planning
PCBUs must prepare an emergency plan for their workplace. Extreme Venues Ltd is the PCBU with the most influence and control over how the stadium is set up during the Safe Smash concert, and so must carry out their duties to the extent that they have the ability to influence and control the matter.
For example, they:
- make sure exit points are clearly marked, easy to access and wide enough to allow crowds of people through
- make sure clearways are easily accessible and clear for emergency services
- make sure that ambulance or other first aid services are in attendance at the venue.
For the night of the concert, Ultra Security are contracted by Extreme Venues Ltd, and they have several responsibilities. Some of these include:
- patrolling the stadium
- closely monitoring the crowd for signs of disorderly or dangerous behaviour
- keeping pathways, exits and clearways open and clear
- notifying emergency services if needed.
These responsibilities are recorded in the emergency plan. On the night of the concert, Ultra Security has the most influence and control over the crowd in the event of an emergency, because they are on the ground and will be in the best position to respond in the first instance. Julie from Extreme Venues Ltd discusses these points with Ultra Security the day before the concert, making sure that everyone knows their responsibilities. She also monitors the situation during the concert by staying in touch with Ultra Security.
This is an example of two PCBUs carrying out their health and safety duties, to the extent that they have the ability to influence and control the matter.
For more information on overlapping duties, see our guidance: Overlapping duties
2.0 Building health and safety into contract management
Lead PCBUs should follow these steps when building health and safety into contract management.
2.1 Scoping the work
At the beginning of any project, think about health and safety before work starts. This is a crucial first step to choosing the best contractors for your job.
You need to be satisfied that the contractors you choose are able to carry out the work in a safe and healthy manner. You should check that they:
- are competent, and
- are qualified to carry out the work.
Examples of how you might satisfy yourself of this could include considering whether they (if they are well established) have a good health and safety record and (if they are not well established) whether they can otherwise demonstrate competency to carry out the work in a healthy and safe manner.
Thinking about health and safety during the tendering process
Throughout the tendering process you must share information with your potential tenderers. This may involve:
- talking to them about what outcomes you want
- the potential tenderers explaining to you how these could be achieved
- talking about what the risks are, and how they will be managed.
The nature of the contract, including the type of work and the level of risk involved, will affect the procedures required. You should consider the broader health and safety implications and give advice on the safety standards to follow.
Before going out for tender, you may wish to carry out preparatory checks and information-sharing, including pre-qualification of potential tenderers. However, pre-qualification is not compulsory.
At this stage, think about:
- the work covered by the contract, and potential health and safety risks
- how health and safety issues will be included in the tender documents
- what health and safety information should be provided to potential tenderers
- whether potential tenderers will be expected to submit a health and safety plan
- how you will assess the health and safety capability of potential tenderers.
Looking at the health and safety management of potential tenderers at the pre- tendering stage emphasises the importance of health and safety. It also means that only contractors with appropriate health and safety practices will be invited to tender for the contract.
2.2 Pre-qualifying the contractor
Pre-qualification is used to establish a shortlist of potential tenderers, looking at the general ability and competence of contractors for the work. You can use this process to help determine how well contractors manage health and safety. It asks potential tenderers to demonstrate an effective health and safety management system, and asks them for information on managing specific risks. You can also use pre-qualification as an opportunity to assist and support contractors to improve their health and safety practices.
The level of detail required for pre-qualification should be appropriate for the type of project, taking its size and complexity into account.
If you choose not to use pre-qualification, health and safety information will still need to be requested and examined in the later stages of the tender.
Information shared in pre-qualification
Appendix 1 shows the type of information that could be requested in a pre- qualification questionnaire. Health and safety information gained (along with information on financials, credit ratings, contract performance and technical information) can be used to develop a profile of potential contractors. Remember that supporting documentation will need to be provided as evidence that good health and safety procedures are in place and are being carried out.
You should encourage tenderers to provide specific answers to your questions, especially when the questionnaire relates to health and safety.
If contractors pass the pre-qualification, they may be placed onto a list of preferred tenderers. Approval may be restricted to certain tasks or occasional activities, depending on the type of work.
Using the pre-tender information
Information gained from pre-tender questionnaires may be recorded and, after the contract has been signed, used to develop and implement a health and safety plan (this is completed by the chosen contractor). It may also be used for selecting future contractors for contracts not requiring a tender process.
2.3 Choosing a contractor
During the tendering stage (whether or not pre-qualification has been used), you should:
- describe potential health and safety risks
- collect information from tenderers on how they intend to manage specific work risks related to the contract. This information should be combined with that from the pre-qualification process.
If pre-qualification has not been used, you also need to gather information from tenderers that will help you assess their competence for the job. Look at their health and safety records to give you an idea of their performance in this area in the past.
You should provide an ‘information for tenderer’ document to potential tenderers that includes health and safety information. The purpose of this document may include:
- bringing health and safety to the forefront of the project
- making sure potential tenderers are fully aware of the health and safety requirements
understanding how potential tenderers will manage contract-specific health and safety risks
- providing a benchmark against which to measure tender applications
- providing a basis for the chosen contractor’s health and safety plan.
What to include in tender documents
Each ‘information for tenderers’ document will be different as the information it contains will depend on the size and nature of the project, and the types of risks involved. The health and safety information included should be tailored to
the specific contract, and the needs of those receiving the information. However, there are some common points that should be included an ‘information for tenderers’ document. Figure 3 illustrates these points.
Health and safety information for tenderers can be included in tender documents in a variety of ways. It could be:
- included as part of the specifications for a project
- presented as a separate health and safety document
- a documented discussion with potential contractors, for smaller jobs.
The information should be appropriate to the project, so that health and safety requirements are built into the tender documents in some form. They should address health and safety from the beginning of the process, clearly defining and acknowledging the health and safety requirements throughout the tendering and awarding process.
The information in the tender documents should mainly come from you. Designers and technical experts can also provide supplementary information about known health and safety risks.
See Appendix 2 for an example of an ‘Information for tenderer’ document that could be adapted for your use. You should use a form like this one to record job details, including related health and safety risks, as preliminary information for contractors.
Tender review, evaluation and choosing a contractor
You should evaluate and assess all tender submissions. Make sure that potential contractors:
- have complied with the tender documents
- have complied with the health and safety requirements for the project
- are competent to carry out the contract.
Assessing health and safety competence
You should give full and careful consideration to the information gained from tenderers at the pre-qualification/tendering stages. This will help you assess the level of competence that each potential contractor holds, and judge their capability where this is critical to health and safety. Ask a competent person for advice if you’re unsure about the competence of potential contractors.
Compliance with health and safety requirements must be a precondition to any tender being successful. Address any deviations before accepting the tender.
Key considerations when choosing a contractor
There are several things you should look at when choosing a contractor. Table 4 illustrates some of the key considerations you might take into account, but is not a complete list as each contracting situation will differ.
Cost may be a factor that you consider, but you should never prioritise this over health and safety. You have a duty to manage risks so far as is reasonably practicable. Don’t choose a contractor based on cost alone.
Table 4: Key considerations when choosing a contractor
You should also closely monitor the selection of subcontractors. If your project has specific health and safety requirements, such as a permit-to-work system or high hazards, you can nominate subcontractors yourself to ensure they are competent to carry out the work. You can assess the competence of individuals by looking at their training, qualifications and past experience. Contractors should seek approval from you before subcontracting any work other than that indicated in the tender.
If your contractors tender for or select their own subcontractors, they must provide potential candidates with information about the project, the site, existing health and safety plans, and any other relevant information. Most of this information will be relayed from the pre-qualification and/or tendering materials you’ve supplied to the lead contractors. Contractors who are hiring their own subcontractors must make sure that they have enough information to ensure site-specific provision for health and safety in their own tendering documents.
You should ensure that:
- tenders are assessed by competent people, with skills and knowledge relevant to the health and safety requirements of the project
- tender evaluation includes adequate consideration of health and safety requirements
- enough time is allocated to assess the health and safety requirements of tenders
- the proposed schedule for the project would not pose a risk to health and safety
- the health and safety performance of potential contractors is adequately assessed
- all tenders are thoroughly reviewed, benchmarking the potential contractor’s health and safety competence against tender requirements.
2.4 Awarding the contract
Once you have chosen your contractor/s, you should start sharing information with them straight away. The lead contractor should develop a contract-specific health and safety plan, and give this to you as soon as possible. Use the plan to monitor the health and safety performance of the contractor for the duration of the project. It may also be included in health and safety documentation and/or the written contract.
Before choosing your contractor, you can hold post-tender meetings with potential contractors to assess whether they are competent in managing health and safety.
We recommend that you make a record of any discussions you have, and agreements you reach around how work will be carried out.
Health and safety requirements should be documented, and become part of the written contract. These requirements may include:
- managing project-specific risks
- conforming with standards
- coordination and reporting requirements
- other project-specific information.
Briefing the contractor
You must make sure that your workers, contractors and their workers, and others, are provided training, information, instruction and supervision to protect them from risks to health and safety arising from the work. This may include induction training regarding the site or type of work, and the opportunity to ask about health and safety risks. The type of training needed will be unique to each project, the worksite and the type of work being carried out.
If you’re sharing information with your contractor, you can use a job registration form. This form can work as a collaborative tool between lead PCBUs and their contractors, to assess the risks associated with the work and decide on the control measures to be put in place.
See Appendix 3 for an example of a job registration form that could be adapted for your use. The type and number of questions will depend on the nature of each individual project, and the example form should only be used as a guide.
Effective information sharing between you and your contractors is essential at all stages of a project.
Table 5 illustrates some key points that could be included in information shared between parties involved in a project.
|Nominated contacts for the lead PCBU and contractors||
Representatives nominated should:
|Planning and running of joint meetings||
Joint meetings should:
|Procedures for reporting risks||
For effective risk management and reporting, there should be:
You must notify us before you carry out certain types of work, such as asbestos removal. You should:
|Accident and incident reporting||
You should make sure that:
Table 5: Key points to include in information sharing
2.5 Monitoring the contract
You, or someone you nominate, should monitor the contract for its duration. This includes:
- monitoring the performance of contractors and subcontractors, including their health and safety performance
- monitoring work conditions and practices
- bringing unsafe conditions or practices to the attention of the contractors
- making sure that unsafe conditions or practices are managed.
- The person monitoring the contract should be appropriately trained to carry out the monitoring.
Actions when monitoring a contract
Monitoring a contract is part of your overlapping duty to consult, cooperate and coordinate with the other PCBUs that you share duties with. Monitoring the contract can include (this list is not exhaustive):
- managing the PCBU/contractor relationship
- making sure all parties are aware of their roles and responsibilities throughout the contractual framework
- taking overall responsibility for the control and coordination of the contract
- holding regular meetings to review health and safety performance
- carrying out regular inspections, as appropriate
raising issues that require attention by the contractor
- investigating and responding to accidents and incidents
- recording health and safety progress for use in future contracting situations
- regularly reporting to the contractor on performance
- carrying out a post-contract review.
2.6 Post-contract review
When the work has been completed, you should review the quality of the work against the job specification and the performance of the contractors. You should consider, among other things:
- how well the contractor fulfilled the health and safety plan
- how well the contractor managed health and safety while completing the work
- any improvements that could be made
- whether the contractor is suitable for future contracts.
