About this Document
A Concrete Pour Checklist is a vital document for anyone in the Australian construction industry. It serves as a final verification step to ensure the site is safe, the formwork is correct, and the concrete mix meets the required specifications. This guide explains everything you need to know about creating and using this checklist to run a smooth and compliant operation. In Australia, construction work is heavily regulated. You cannot simply turn up and pour concrete without considering your legal obligations. This checklist helps you meet those obligations. It is not just about the concrete quality. It is about the safety of your workers and the public. The Work Health and Safety Act 2011 imposes a primary duty of care on a person conducting a business or undertaking. This means you must ensure the health and safety of workers while they are at work. Using a checklist helps you manage these risks. It provides a written record that you have identified hazards and controlled them before work starts. If an inspector visits your site or if an incident occurs, this checklist becomes evidence of your compliance. You need this document whenever you undertake a concrete pour. It applies to small jobs like residential driveways and large jobs like commercial foundations. The principles remain the same. You must check the ground conditions, the formwork stability, the weather, and the concrete delivery docket. If you are pouring near power lines or excavations, the risks are higher. The checklist prompts you to look for these specific hazards. Using the document is straightforward. You or your site supervisor should walk through the site before the concrete truck arrives. You check the boxes for each item. If an item is not right, you fix it before the pour starts. You record the date, the location, and the names of the workers on site. You should also record the weather conditions. Rain can ruin a concrete pour and create site hazards. If there is a risk of rain, the checklist helps you decide whether to proceed. The checklist also covers the concrete itself. You must check the delivery docket from the supplier. It must match the ordered strength grade and slump. You need to verify the volume is correct. In Australia, concrete standards are strict. AS 1379 specifies the requirements for concrete supply. You should reference this standard on your checklist to show you follow industry best practice. Another key area is formwork. AS 3610 covers the design and construction of formwork. Your checklist must include a check for formwork stability. You look for adequate bracing and support. You check that the form faces are clean and oiled. You check that the joints are tight to prevent grout loss. If the formwork fails during the pour, it can cause serious injury. The checklist helps you catch loose props or weak bracing before you place the load. Personal Protective Equipment is also a mandatory part of the checklist. Under the WHS Regulations, workers must wear certain PPE. This usually includes safety boots, high visibility clothing, and sun protection. If the concrete is being pumped or if there is a risk of splash, workers need gloves and eye protection. The checklist confirms that everyone on site is dressed correctly. It is much easier to fix a PPE issue before the truck arrives than to stop work once the pour has started. Plant and equipment also need checking. If you are using a concrete pump, it must be inspected and tagged. Exposed moving parts must be guarded. The checklist confirms that the pump operator holds the necessary high risk work licence if required. You also check that the vibrators and screeds are working. A breakdown during a pour can lead to a cold joint, which weakens the structure. The checklist helps you ensure your gear is ready to go. A common mistake is treating the checklist as a formality. It is not. It is a risk assessment tool. Some contractors just tick the boxes without looking. This is dangerous and provides no legal protection. If an incident happens, the regulator will look at your records. If the checklist is ticked perfectly but the site is a mess, they will know you were not diligent. You must use the checklist honestly. Another mistake is not keeping the records. You should file the completed checklist with your other project documents. Keep it for at least seven years. The ATO requires you to keep business records for five years, but safety records should be kept longer in case of a claim for latent defects. Insurance companies will also ask for these records if there is a claim for property damage or injury. The checklist also helps with subcontractor management. If you hire a subbie to do the pour, you should review their checklist. As the principal contractor, you have a duty to ensure they work safely. Asking to see their pre-pour checklist shows you are taking reasonable steps. It creates a culture of safety on site. It sets clear expectations. It makes professional behaviour the norm. In terms of specific Australian legal requirements, the WHS Act 2011 is the big one. Section 19 outlines the primary duty of care. It requires you to eliminate risks so far as is reasonably practicable. If you cannot eliminate them, you must minimise them. The checklist is part of your risk minimisation strategy. The Code of Practice for Construction Work provides further guidance. It suggests using checklists to manage common hazards. If you work in a Commonwealth jurisdiction, the Work Health and Safety Act 2011 (Cth) applies. The principles are the same across all states and territories. You should also be aware of the Environmental Protection Acts in your state. Concrete run-off can harm waterways. Your checklist should include a check for washout facilities. You must ensure slurry does not enter stormwater drains. Failure to manage this can lead to hefty fines from the EPA. Financial records are another consideration. The checklist often forms part of the evidence required to claim progress payments. The client or the head contractor may want to see that the pour was completed to specification before they pay the invoice. A signed checklist acts as proof of delivery and quality. It confirms the work was done according to the contract. When you complete the checklist, you should sign it. If you are the supervisor, you sign off on the readiness. If an issue is found, record it. Record the action taken to fix it. If the pour is cancelled due to weather or other issues, write that down. This creates an audit trail. It shows you acted professionally and did not cut corners. Small business owners often feel overwhelmed by paperwork. However, this simple document can save you time and money. It prevents rework. It prevents injuries. It prevents fines. It takes ten minutes to complete but can save your business. It helps you sleep at night knowing you did the right thing. It covers the basics like site access. You need to check that the concrete truck can get in and out safely. You need to check that there is room for the pump. You need to check that ground is stable for heavy machinery. If the ground is soft, the truck might get bogged. The checklist prompts you to check crane or pump outriggers. They must be on bearers or pads to stop them sinking. This is a major cause of incidents on construction sites. The checklist helps you avoid these obvious but easily overlooked traps. Communication is another key benefit. When the foreman hands the checklist to the crew, everyone knows what to expect. It ensures the whole team is on the same page. It clarifies roles. It confirms who is doing the screeding and who is doing the finishing. It confirms who is watching the pump line. Good communication reduces the chance of errors during the pour. Errors in concrete are expensive to fix. Once concrete sets, it is very hard to change. The checklist is your last chance to get it right before the chemical reaction starts. You check the levels one last time. You check the reinforcement chairs are not displaced. You check that the service penetrations are in the right place. This attention to detail is what separates a professional from an amateur. In summary, the Concrete Pour Checklist is a tool. It covers safety, quality, compliance, and logistics. It is relevant to every business that works with concrete. It is a practical application of the law. It turns legal obligations into easy steps. It protects your workers, your clients, and your business. It is an essential part of the construction process in Australia. Do not start a pour without one.

Site Preparation
Checks for ground stability, access, and weather conditions.
Accessibility for Heavy Machinery
Verify that all access roads and ramps are constructed to support the combined weight of concrete trucks, pumps, and cranes. The ground must be level and stable to prevent machinery rollover or bogging. Under the Work Health and Safety Regulation 2011 (WHS Regulations), specific duties apply to managing the risks of plant movement. If using mobile cranes, ensure the ground complies with AS 2550.1 (General requirements) regarding ground bearing capacity.
Check the width of access paths. They must be sufficient for heavy vehicles to pass without obstruction. Remove all overhead obstructions, such as low-hanging power lines or tree branches, which pose a significant electrocution or collision risk. If work is near overhead power lines, refer to the Electrical Safety Act 2002 (QLD) or equivalent state legislation for safe approach distances and "Look Up and Live" requirements. Ensure there is adequate turning space for concrete agitators to exit the site without reversing, or implement a traffic management plan if reversing is unavoidable.
Ground Compaction and Stability
You must inspect the sub-grade where the concrete will be poured. The ground requires proper compaction to prevent future slab settlement or cracking. Check that the soil is uniform and free from soft spots, organic matter, or loose fill. If the sub-grade has been recently excavated or filled, it must be compacted according to AS 2870 (Residential Slabs and Footings) to achieve the necessary density.
For formwork, check that the sole plates are adequately supported and compaction is sufficient to hold the concrete weight without displacement. If the site is on reactive clay, ensure soil moisture content is managed to prevent heave or shrinkage that compromises the structure before the pour.
Environmental Protection and Weather Safety
Assess the weather forecast immediately prior to the pour. If rain is imminent, ensure adequate drainage is in place to stop water flowing into the formwork or pooling under the slab. Water saturated sub-grades weaken the concrete mix and can lead to structural failures. Have plastic sheeting and tarpaulins ready to cover the pour area at short notice. Compliance with Environmental Protection Act regulations in your state is necessary to ensure concrete slurry or runoff does not enter stormwater drains.
Check wind conditions. High winds can affect the operation of concrete pumps and crane placement, creating uncontrolled loads. Secure all loose materials on site, such as formwork pins and timber, to prevent them becoming projectiles in strong winds. If dust is an issue due to wind, implement dust suppression measures to meet local environmental requirements.
Formwork Inspection
Verification of the formwork structure and stability.
Formwork Inspection
Check all formwork supports and braces before you order the concrete. The framework must be strong enough to handle the weight of the wet concrete, the workforce, and any equipment like concrete pumps or vibrators. Inspect props and scaffolding to ensure they are vertical, plumbed, and sitting on firm ground. Use sole boards if the ground is soft to prevent the props from sinking. Adjust the telescopic props until they are tight and locked securely. Double check all wedges and locking pins are in place. If you are using timber, make sure it is not warped, rotten, or damaged. Refer to AS 3610 Formwork for concrete for specific guidance on tolerances and support pressures.
Verify the exact dimensions and alignment of the formwork against the approved plans. Measure the length, width, and depth of the pour to ensure they match the engineering specifications. Check the levels of the formwork using a laser level or spirit level. It is vital that the formwork is level and straight. Make sure the joints are tight and sealed properly. If there are gaps between the sheets of formwork, grout may leak out during the pour. This causes honeycombing in the concrete and weakens the structure. Tape any gaps or apply foam sealant where necessary.
Clean the inside of the formwork thoroughly. Remove all wood offcuts, sawdust, wire, tying wire, and debris. If you leave rubbish inside the boxes, it will become permanently embedded in the concrete once it sets. This looks unprofessional and can compromise the structural integrity of the slab or element. Sweep or blow out the forms just before the pour begins.
Apply the recommended release agent or oil to the inside face of the formwork. This stops the concrete from sticking to the timber or steel when you strip the forms. Do not use old engine oil or diesel because contaminants in the oil can discolour the concrete or prevent it from curing properly. Apply the oil evenly but do not overdo it. Puddles of oil can actually prevent the concrete from hardening near the surface. Ensure the oil does not get on the reinforcement steel, as this will stop the steel from bonding with the concrete.
Inspect the tie wires and clamps. Ensure they are tight enough to resist the pressure of the concrete. If the ties are too loose, the formwork will bow or burst, causing the concrete to spill out. Finally, walk the perimeter and confirm all safety rails are in place if working at heights. Ensure the work area complies with the Work Health and Safety Act and regulations regarding fall protection. Sign off on the check sheet only when you are 100% satisfied the formwork is ready.
Rebar and Reinforcement
Checks for steel placement and support chairs.
Confirm all reinforcement bars and mesh are placed strictly in accordance with the approved engineering drawings and specifications. Start by cross-referencing the plans with the installed steel. Check for correct bar sizes, grades, and spacing. Ensure the mesh and bars form a rigid matrix and are securely tied together with wire at sufficient intervals to prevent displacement during the pour. All starter bars and dowels must be accurately positioned and firmly fixed to maintain their correct alignment and location.
Concrete cover is critical to prevent corrosion and ensure fire resistance. You must provide the exact concrete cover specified in the engineer's design. This is the distance between the outer surface of the concrete and the nearest surface of the reinforcement. Place bar chairs, spacers, and support blocks at tight enough intervals to support the weight of the steel and the wet concrete without sagging or settling.
Do not use bricks, stones, or aggregate offcuts as spacers. Only use purpose-made concrete, plastic, or steel bar chairs and spacers designed for the specific application. For ground slabs on vapour barriers, use plastic bar chairs with a large base footprint or concrete spacers to prevent puncturing the membrane. Ensure the spacer type and height match the specified cover depth. In vertical applications like walls and columns, use clips, ties, or concrete spacers fixed to the formwork or reinforcement to keep the steel centered.
Verify lap lengths and starter bar connections. These laps must overlap for the full distance required by the design code to transfer load effectively. Ensure lapped bars are securely tied and positioned so they do not create concrete honeycombing.
Compliance with AS 3600 Concrete Structures and AS 1379 Specification and Supply of Concrete is mandatory. Ensure all work meets the requirements of the National Construction Code (NCC). Before pouring, clean the formwork and remove all debris, timber offcuts, and wire clippings from the reinforcement area. A clean pour ensures proper bonding and prevents structural weaknesses. Finally, call for a formal inspection and sign-off from the building surveyor or structural engineer if required by your permit or the specification. Do not pour concrete until you receive this approval.
Plant and Equipment
Safety and operational checks for machinery.
Concrete Pumps
Visually inspect the concrete pump and placing boom for structural damage, leaks, or wear on hydraulic hoses. Check that outriggers are stable and deployed on adequate bearing pads, ensuring the pump is level. Verify the safety cage and access platforms are secure. Examine the delivery line for wear or clamps that may be loose. Ensure the pump operator holds a current High Risk Work Licence (HRWL) class CN for concrete pumps and booms, as required by the Work Health and Safety Regulation 2011 (Cth) or relevant state equivalent. If the pump is mobile, check the registration sticker and third-party insurance is current. Confirm all emergency stop switches on the pump and remote control are functional. Ensure a spotter is assigned to direct the pump operator during pipeline movement.
Concrete Vibrators
Inspect all immersion vibrators (pokers) and drive units for damaged power cords or electric leads. Check the plug tops are intact and the earth connection is secure to prevent electric shock, referencing AS/NZS 3000 Wiring Rules requirements for portable equipment. Test the On/Off switch to ensure it cuts out immediately when released. Check the flexible drive shaft for kinks or exposed wires. Verify the vibrator head is securely attached to the shaft. Ensure the plant is fitted with a current inspection tag and tested in accordance with the Work Health and Safety Regulation standards for electrical equipment. Ensure operators are trained in safe manual handling techniques to prevent vibration white finger or repetitive strain injuries.
Screeds and Power Trowels
Check mechanical screeds and power trowels for sharp, exposed blades or cutting edges. Ensure all safety guards are in place and firmly secured. Inspect throttle controls and dead man handles to ensure they operate correctly. Verify that all nuts, bolts, and fixings are tight to prevent mechanical failure. Check that the plant has a current risk assessment tag attached. Ensure operators are wearing appropriate Personal Protective Equipment (PPE), specifically safety boots with steel caps to protect against the rotating blades. Confirm noise levels are managed in line with the Work Health and Safety Regulation codes of practice for managing noise and preventing hearing loss.
General Plant Requirements
Confirm all plant and equipment on site has a current tag for service and inspection. Verify that all operators hold the necessary licences and high risk work licences specific to the machinery they are using. Check that operators have signed in to the site induction register. Ensure all machinery is positioned to maintain safe egress routes and does not create a trip hazard for workers on the pour. Inspect fuel storage areas to ensure they are secure and clearly labelled to comply with AS 1940 The storage and handling of flammable and combustible liquids.
Concrete Delivery
Verification of the concrete mix and docket.
Check the Concrete Delivery Docket against the original order immediately upon the truck’s arrival. Ensure the delivery matches the purchase order in every detail to prevent disputes and non-compliance issues. Verify the concrete strength grade, such as 20MPa, 25MPa, 32MPa, or 40MPa, as specified in your project plans. Confirm the aggregate size, typically 10mm or 20mm, and the specified slump class. Check that the volume of concrete in cubic metres matches the amount ordered and the ticket records the correct mix design number. The time shown on the docket is critical. Under AS 1379-2007 Specification and supply of concrete, the concrete must be discharged within 90 minutes of the addition of mixing water. If the ticket indicates the batch is old, reject the load immediately.
Pay close attention to admixtures listed on the docket. If the concrete requires retarders for hot weather or accelerators for cold conditions, these must be documented. Traceability is a legal requirement for safety-critical work. Ensure the docket displays the Batching Plant ID and the unique Batch Number. Australian Work Health and Safety (WHS) regulations require that you keep this docket on site for inspection. It serves as your primary evidence of compliance with the National Construction Code (NCC) and the Building Code of Australia (BCA).
Perform a visual inspection of the concrete in the truck chute before unloading begins. Look for signs of segregation or bleeding, where the aggregate separates from the paste. The concrete should appear cohesive and uniform. If the mix looks too dry or too soupy, it may not meet the engineer’s specifications.
Conduct a slump test to verify workability. While a laboratory test is precise, a site test is essential for practical verification. Using a standard slump cone, fill it in three equal layers and rod each layer 25 times with a steel tamping rod. Remove the cone immediately and measure the vertical distance between the top of the cone and the displaced concrete centre.
Compare this measurement to the specified slump on the delivery docket. A variance greater than plus or minus 15mm generally indicates a problem that requires correction. If the slump is outside the specified tolerance, do not accept the load. Notify the batching plant dispatcher immediately. Adjusting the water content on-site without the explicit approval of the concrete supplier and the supervising engineer is a breach of AS 1379 and will void the warranty on the concrete strength. This practice severely compromises the structural integrity of the pour and poses significant compliance risks.
