Why concrete works tenders behave differently

Every other project-type guide in this library describes a job with a start and a finish. An earthworks package moves a defined volume of material. A drainage package lays a defined length of pipe. A road rehabilitation package resurfaces a defined chainage. You price it, you build it, you hand it over.

Concrete works usually is not that. Kerb and channel, footpaths and vehicle crossings are the assets a council renews continuously, in small scattered increments, forever. Councils publish annual renewal programs and describe them in exactly those terms — a rolling program of works, notified street by street, with driveway crossovers picked up opportunistically while the crew is already in the street.^[1] So instead of tendering a project, you are usually tendering a rate: a price per lineal metre of kerb, per square metre of path, per vehicle crossing, that a council can call on for the next two or three years. The same rate schedules are frequently used for path, hardstand and carpark work inside reserves, covered in our guide to parks, sport and recreation civil works.

That single structural difference reshapes the whole bid. Three consequences matter most:

• Your rate has to survive inflation you cannot see yet. A three-year term with a 30-month extension option means the rate you write in July 2026 may still be governing work in 2031.^[2] Whether the contract lets you adjust it is a clause-level question, and if the clause is not there, it does not exist.
• Your rate has to work at every job size. The same per-metre rate that covers a 300 m street replacement also covers an 8 m infill between two driveways. Mobilisation, traffic control and minimum concrete loads do not scale down. Price for the average and the small work orders eat your margin.
• Your compliance load is heavier per dollar than on any other civil work type. You are cutting concrete in a live pedestrian environment, on an accessible path of travel, metres from private property, under a specification that mandates the saw-cutting that generates your worst dust hazard. The paperwork does not shrink because the job is $14,000.

This guide assumes you already know how to write a compliant civil tender. If you do not, start with the complete guide to writing a winning civil construction tender and how government tenders are scored. For the generic structure of a methodology statement, use the construction methodology statement guide — this article does not repeat it. What follows is the material specific to concrete works, and it is weighted towards the commercial mechanics, because that is where these bids are actually won and lost.

The five shapes council concrete work arrives in

Before you decide whether to bid, work out which of these you are looking at. The label on the portal is unreliable — read the conditions, not the title. Our guide to tender types covers that discipline in general; here are the five shapes concrete work specifically takes.

1. The programmed renewal contract (schedule of rates, multi-year)

The dominant form. Council has an asset register, a condition rating and a renewal budget. It tenders a schedule of rates for footpath, kerb and channel and vehicle crossing works, then issues work orders against it. Terms of three years plus extension options are standard, with the extension at council’s sole discretion and conditional on performance.^[2] This is the highest-value form to win and the easiest to lose money on.

2. The response and maintenance contract

Often bundled with the renewal program. Council needs defects made safe on a response clock — a trip hazard reported on Monday must be attended within a defined window. AUS-SPEC treats footpath repair as a distinct maintenance activity aimed at removing defects that could constitute a safety hazard to pedestrians, and points to IPWEA practice guidance for inspection and condition assessment.^[3] If the tender bundles programmed and response work, price them separately. Response work carries mobilisation for a few square metres and a KPI attached to liquidated damages or a performance regime.

3. The discrete street reconstruction (lump sum)

A single street where the kerb and channel replacement sits inside a broader reconstruction — pavement, drainage upgrade, new crossovers and footpath together. Here concrete is one work element among several, and you are competing against contractors bidding the whole package. If the pavement and drainage scope is the larger share, read the road construction guide and the drainage and stormwater guide alongside this one.

4. The panel or standing offer

Council establishes a panel of pre-approved concrete contractors and then quotes work among panel members, usually through VendorPanel or an equivalent platform. Getting on the panel is a capability and rates exercise; winning work afterwards is a separate, ongoing quoting discipline. Our VendorPanel guide covers how that machinery works and how quote requests actually reach you.

5. The subdivision or developer-works package

Private client, council specification. The work is built to the council’s engineering design and construction manual and handed over as a public asset, so the technical requirements in this guide still apply in full — but the commercial framework is a private contract, not a government procurement. Payment security, retention and defects liability behave differently, and the go/no-go calculus changes. Use the go/no-go framework and read our security of payment guide before committing crew to a developer package.

Reading the pricing schedule before you price it

On a schedule of rates concrete contract, the pricing schedule is the contract. Everything commercially important is in the item descriptions, the units and the notes underneath — and most contractors start filling in numbers before they have read any of it.

Five questions to answer first, in this order.

What unit is each item measured in, and where does measurement start and stop?

Kerb and channel is almost always lineal metre. Footpath is square metre or lineal metre of a stated width. Vehicle crossings and pram ramps are usually “each”, which is where the trouble starts, because a crossing on a 1:20 grade in a 4.5 m verge is not the same job as one on flat ground in a 2.5 m verge. Check whether the schedule separates residential from commercial and industrial crossings; if it does not, you are pricing a single rate across genuinely different jobs.

The measurement rules for kerb and channel are not left to you. Road authorities embed them in their own specifications rather than relying on a single national civil method of measurement — Transport for NSW sets them out in its kerbs and channels specification, and Queensland’s Transport and Main Roads publishes a specific measurement checklist for concrete kerbs, kerb channel, crossings and dykes.^[4][5] Find the measurement clause. If the specification measures kerb along the face of kerb and you priced along the back, you have mispriced every curve on the contract.

What is bundled into the rate and what is a separate item?

This is the single most common source of loss. Saw cutting, excavation, spoil disposal, bedding material, reinstatement of the adjoining pavement and topsoil and turf behind the kerb are all either separate schedule items or deemed included in the unit rate. The specification usually decides. AUS-SPEC’s kerb and channel worksection requires saw cutting along the existing kerb, footpath, driveway and road pavement before removal, requires damage to the remainder to be minimised, and requires damaged footpath, driveway and road pavement to be reinstated to pre-construction condition.^[6] If none of that appears as a priced item, it is inside your rate whether you allowed for it or not. Dust and silica controls on cutting and grinding sit in the same category — see our guide to noise, vibration and dust management.

Is traffic management a rate, a provisional sum, or deemed included?

On footpath and kerb work in a residential street, traffic and pedestrian management can be a material share of the cost of a small work order. Some councils schedule it separately by day. Some treat it as a provisional sum. Some deem it included. The three produce completely different rates, and a bid priced on the wrong assumption looks either uncompetitive or suicidal.

Is there a minimum work order value, a minimum quantity, or neither?

A minimum charge per work order — or a stepped rate for quantities below a threshold — is the difference between a viable and an unviable schedule. If the tender does not offer one, ask for one in your clarifications. Asking is free and the answer tells you how the council thinks.

Which contract form sits behind the schedule?

For work in the $50K–$2M band you will most often see a minor works form. Standards Australia publishes two — AS 4905 for superintendent-administered contracts and AS 4906 for principal-administered contracts, both derived from the earlier AS 4305.^[7] NSW Government agencies use their own Minor Works form, MW21, which the state describes as suited to construction contracts up to $2 million that are non-complex or repetitive in nature, with a separate Mini Minor Works form for contracts up to $250,000 under the general construction works scheme.^[8][9] The phrase “repetitive in nature” is the tell: these forms were written for exactly the rolling renewal work this guide describes.

Larger or bundled packages may use AS 2124 or AS 4000. The differences matter for variations, extensions of time and delay costs — our AS 4000 vs AS 2124 guide compares them clause by clause. Note in particular that where design is not developed enough for a fixed price, AS 2124 contains a specific provisional sum mechanism that adjusts once the final cost is known.^[10]

What has to sit inside each unit rate

We cover first-principles rate build-up in detail in the civil works cost estimating guide, including a worked kerb and channel build-up. Rather than repeat that method, here is the concrete-works-specific checklist of cost components that get missed. Work through it against your own rate before you submit.

Cost component	Why it gets missed on concrete works
Saw cutting of existing concrete and pavement	Mandated by the specification before removal, but frequently not a scheduled item. Also the trigger for your silica obligations (see below).
Demolition, load-out and disposal of existing kerb, path or crossing	Concrete waste disposal gate fees vary widely by region and have moved with landfill levies. Confirm your tip cost per tonne, not a remembered figure.
Bedding and subgrade preparation	Specifications commonly require soft, wet or unstable material to be removed to a minimum depth below the underside of bedding and replaced with compacted bedding material.[11] On renewal work you do not know the condition until you break out.
Minimum concrete load and short-load charges	An 8 m infill does not need a full truck, but you pay for one. On a scattered work-order geography this is a structural cost, not an exception.
Reinforcement where specified	Mesh requirements are specification-driven, not universal — VicRoads specifies SL72 mesh for concrete paving where reinforcement is called for.[11] Council annexures vary. Do not assume unreinforced.
Curing and protection	Curing compound application rates are specified, not discretionary. TMR requires the spray rate in each pass to be the higher of 0.30 litres per square metre or 50% more than the rate on the product’s certificate of compliance.[12] That is a real material cost per square metre.
Traffic control, pedestrian detours and property access	Every crossing you remove cuts a resident’s access. Temporary access provision, matting, and out-of-hours pours to keep a business trading are real costs.
Reinstatement behind the kerb	Topsoil, turf, driveway tie-in, service pit adjustment and letterbox or fence reinstatement. The specification requires pre-construction condition; residents enforce it.
Testing and NATA laboratory fees	Council specifications commonly require the contractor to engage a testing authority holding current NATA registration for the relevant tests and to forward results without delay.[13]
Survey and set-out	Level and grade tolerances on kerb and channel are tight (see below) and pram ramps must land on compliant grades. TMR publishes survey tolerances specifically for kerb, channel and footpaths including pram crossings.[14]
Silica controls, air monitoring and health monitoring	Post-2024 this is a standing cost of doing concrete work, not a project allowance. Detail in section 9.
Rework and defects allowance	Concrete is unforgiving. A path outside crossfall tolerance or a kerb outside the straightedge tolerance comes out. Allow for it or absorb it.

One structural warning about how you distribute margin across the schedule. It is tempting to load the rates you expect high volumes of and shade the ones you expect little of — front-end loading, in effect. Two reasons not to. First, you do not control the mix: a council that shifts its program towards vehicle crossings can turn your “unlikely” item into half the work. Second, evaluators comparing rate schedules across bidders notice distribution anomalies, and a schedule with one wildly out-of-market rate invites questions about the whole submission. Our guide to pricing strategies for government tenders covers the broader discipline.

Rise and fall: the clause that decides whether your rates survive the term

This is the section most concrete tenders get wrong, and it is the reason this guide exists as a separate article rather than a section inside the road construction guide.

A rise and fall clause — also called a price escalation, cost adjustment or fluctuation clause — adjusts the contract price when the cost of specified inputs moves after the tender date. It identifies which inputs are covered, sets a base index or base price, and gives a formula. Its function is to allocate cost fluctuation risk. Without one, the contractor carries all of it.^[15]

Four things every civil SME tendering a multi-year concrete schedule needs to understand about it.

It is never implied. If it is not written in, it does not exist.

Cost escalation clauses must be expressly included.^[16] The standard general conditions of AS 4000-1997 and AS 4902-2000 contain no rise and fall mechanism; AS 2124-1992 and AS 4300-1995 were drafted when annexing one was commonplace and allow the parties to attach it.^[17] NSW’s GC21 takes a different approach again, carrying a standard costs adjustment formula in a dedicated schedule, with the contract price fixed for a period from the date of the contract before adjustment begins.^[17] Search the whole tender package — schedules and annexures included — for the terms rise and fall, price adjustment, cost adjustment, escalation, fluctuation and index adjustment.^[15] If none appear, you are tendering a fixed rate for the full term and your price must say so.

On a schedule of rates, each item needs to be assigned to an index class

Where a rise and fall clause applies to a schedule of rates, the apportionment exercise required on a lump sum is unnecessary — but each item on the schedule still has to be assigned to a class of materials, such as concrete products, which determines which price index applies to it.^[18] If the tender’s escalation schedule assigns your kerb and channel item to a general construction index rather than a materials index, that is a commercial decision made for you, and it can be worth arguing at clarification stage.

Which index is chosen matters more than whether escalation exists at all

The ABS publishes both output indexes for construction industries and input indexes for construction materials, and they are not the same thing. Output indexes for civil work sit under the industry classes for road and bridge construction and other heavy and civil engineering construction; materials indexes sit under manufacturing.^[19] The gap between them is not academic. In the year to the June quarter 2025, the ABS reported heavy and civil engineering construction output prices up 1.9%, with the road and bridge construction index rising 0.8% for the quarter — while the cement, lime, plaster and concrete products index rose 3.9% for the quarter, driven by sustained construction demand and rising labour, materials and energy costs.^[20]

If your concrete rates are indexed to a construction output series and your actual exposure is to ready-mixed concrete, you carry the difference. Say so in your bid if the escalation schedule allows comment.

Escalation cuts both ways, and thresholds and caps eat what is left

“Rise and fall” is literal. In the September quarter 2025 the ABS reported the concrete, cement and sand index down 0.6%, with ready-mixed concrete down 1.3% as suppliers lowered prices amid increased competition.^[21] Under a symmetrical clause, that is a reduction in your rates. By the March quarter 2026 the same index was rising again on elevated raw material, labour and energy costs.^[22] Volatility in both directions is the normal condition.

On top of that, it is common for parties to agree that the contractor cannot claim escalation until total escalation exceeds a contractually agreed threshold, usually a percentage; less commonly, any contingency already in the contract price is required to absorb escalation before the right to claim is enlivened.^[23] Combined with base date limitations and caps, escalation recovery frequently lands well below what has actually been spent.^[15]

And note what is usually not in the basket: fuel. Concrete renewal work is cartage-intensive — concrete delivery, spoil out, plant shuffled between scattered work orders — and diesel is exposed to shocks that no concrete index captures. In the March quarter 2026 the ABS recorded petroleum refining and petroleum fuel manufacturing up 10.1% on oil price movements following the closure of the Strait of Hormuz late in the quarter.^[22] A fuel-blind escalation clause on a three-year term is a risk you price for, not a risk you recover.

Quantity risk and the “no guaranteed volume” problem

Almost every schedule of rates concrete contract states that the quantities shown are estimates only and that the council does not guarantee any volume of work. Read that clause carefully, because it does two things at once: it removes your revenue certainty, and it usually removes your entitlement to a rate adjustment if the actual mix diverges from the estimate.

Some contracts contain a quantity-variation provision that allows rates to be revisited when actual quantities depart materially from the schedule. Where such a provision exists, understand that a change in quantities does not automatically produce a rate adjustment — adjustments have to be justified by reference to the specific operation affected, not asserted in the abstract.^[24] Build the argument at the time, in writing, against the operation and its cost drivers.

Practical positions to take at tender stage:

• Find and read the quantity-variation and provisional quantity clauses before pricing. If the contract has neither, your rates must be robust across the full plausible range of the program, not tuned to the indicative quantities.
• Do not resource for the estimate. A schedule with no volume guarantee cannot justify a dedicated crew and a new kerb machine on its own. Model the contract as incremental work against existing capacity, then check whether it still stacks up.
• Ask about program visibility. Councils that publish forward renewal programs and notify affected streets in advance are giving you planning information you can price against.^[1] Ask in clarifications how far ahead work orders will be issued. The answer changes your rate.
• Check the exclusivity position. A sole-supplier schedule and a panel schedule with three other contractors quoting on every job are entirely different commercial propositions at the same rate.

The specification stack — and why the council’s annexure wins

Concrete works tenders reference more documents than most bidders realise, and they sit in a hierarchy. Getting the hierarchy wrong produces a methodology that quotes the wrong tolerance and a rate built on the wrong concrete grade.

Local government: AUS-SPEC, plus the council’s own annexure

Most Australian councils specify concrete works through AUS-SPEC, the local government master specification system published alongside NATSPEC. Its stated aim is to give councils technical and contractual consistency while allowing them to edit and add project-specific requirements.^[25] The worksections you will meet on concrete work include 1122 Kerb and channel (gutters) — covering construction of new kerb and channel and associated works including component foundations, gully pit adjustment or replacement, reinstatement of pavement and driveways, and removal and disposal of the existing kerb and channel — plus 0319 Auxiliary concrete works for concrete properties, delivery, placing, compaction, finishing, curing and protection, 1354 Drainage structures for new gully pits, and the maintenance worksection 1431 Footpath paving repairs.^[26][3][6]

Two points about AUS-SPEC that separate a competent bid from a generic one.

First, the worksection is explicitly not a self-contained specification — it operates in addition to other worksections, and cross-references external guidance including the Austroads road design guidance.^[27] Quoting 1122 alone in your methodology signals you have read one document.

Second, and more importantly: councils customise the template with their own office-master text and annexures, and the council’s specific clauses prevail over the base text.^[27] This is the trap. Two neighbouring councils can both say “AUS-SPEC 1122” and require different concrete grades, different joint spacings and different tolerances. If your tender library holds a methodology built on one council’s version, you cannot lift it into the next bid without checking the annexure. Our tender content library playbook covers how to structure reusable content so that specification-specific values stay flagged as variables rather than hardening into assumptions.

State road authorities

Where the work is on a state-controlled road, or where a council has adopted the road authority’s specification, a different stack applies:

• New South Wales. Transport for NSW specification R15 covers kerbs and channels (gutters), including joint types, joint sealing, and the interaction between joints in a concrete base and joints in the kerb alongside it.^[4]
• Victoria. VicRoads Standard Specification Section 703 General Concrete Paving governs footpaths, edgings, other surfacings, shared use paths and kerb extrusion. It specifies normal-class concrete to AS 1379 for edgings, footpaths and other surfacings, a higher grade for shared use paths, and — notably — permits equivalent geopolymer concrete as defined in the section.^[11]
• Queensland. Kerb and channel is constructed in accordance with the drawings and MRTS03 Drainage, Retaining Structures and Protective Treatments, with concrete requirements in MRTS70 Concrete and ancillary works covered by MRTS41.^[12][5] Note that TMR is progressively harmonising its technical specifications with the Austroads Technical Specifications and publishing them as combined documents rather than Queensland supplements, so specifications now issue under titles marked as harmonised.^[28] Check the edition referenced in your tender, not the one you used last year.

The Australian Standards underneath

Whichever specification governs, the same standards sit beneath it. Council standard drawings for kerb and channel routinely reference AS 1379 for the specification and supply of concrete, AS 2876 for concrete kerbs and channels, and AS/NZS 4671 for steel reinforcing materials.^[29] AS 2876 specifies requirements for manually placed and machine-placed in-situ concrete kerbs, kerbs and channels, and kerbs and trays, and their geometry, for use in carriageways and footpaths including crossing points — it is the standard your joint forming and preparation will be judged against.^[30]

Also expect to see AS 3600 for concrete structures, AS 1012 methods of testing concrete (including the slump test method), AS 1478.1 for chemical admixtures, AS 3582.1 for fly ash as a supplementary cementitious material, AS 3972 for portland cement, AS 3996 for access covers and grates, AS 4586 for slip resistance classification of pedestrian surfaces, and the AS 1428 series for access and mobility.^[11][31] Footpath pavement design is commonly taken to AS 3727.1, using the requirements for pedestrians and light vehicles.^[32]

Cite the ones your tender actually references. A methodology listing fourteen standards indiscriminately reads as padding; one that cites the four that govern this specification, with the clause numbers, reads as competence. Our guide to addressing selection criteria covers how to structure that evidence so it earns marks rather than filling space.

Grades, joints and tolerances the inspector actually checks

Concrete works has tighter and more frequently measured tolerances than any other work type in this library. Earthworks is judged on density testing at intervals; kerb and channel is judged with a three-metre straightedge on every run. A methodology that states the actual tolerance figures from the governing specification demonstrates something a generic methodology cannot fake.

The numbers below are drawn from published specifications and are illustrative of what a bid needs to address. Use the values in your own tender documents — these vary by jurisdiction and by council annexure.

Requirement	Published example
Concrete grade, kerb and channel	N25 standard strength grade to AS 1379 unless otherwise specified, in both a NSW council standard drawing series and VicRoads kerb standard drawings.[29][33]
Kerb and channel level relative to adjoining pavement	Tolerance of −0 to +10 mm; except on curves or in shaped areas, deviation from a 3 m straightedge not exceeding 5 mm at any point (VicRoads 703.15).[11]
Kerb tolerances under AUS-SPEC 1122	Absolute level tolerance under a 3 m straightedge of ±10 mm at any point on the finished surface; relative level tolerance under a 3 m straightedge of 5 mm to the top or face of kerbs.[27]
Section and profile dimensions	Not differing from the drawings by more than 5 mm, with overall width not exceeding the specified width by more than 15 mm; on dimensions under 25 mm, a tighter tolerance applies. Exceptions at laybacks, grade changes, curves and channel depressions at gully pits.[11][27]
Footpath thickness and reinforcement	VicRoads specifies 125 mm thickness for concrete paving including footpaths, edgings and other surfacings, with SL72 mesh where steel reinforcement is specified.[11]
Footpath alignment and level	Published council examples range from within 6 mm of specified line and level, to within 25 mm at all points with relative deviation between any two points not exceeding 3 mm or 1 in 270 of the distance between them, whichever is greater — in both cases subject to water not accumulating at any point.[34][13]
Control and expansion joints, kerb and channel	Control joint spacing to a stated maximum (3 m in one published NSW council drawing series); isolation joints where the kerb and channel abuts a drainage pit lintel or other structural element; expansion joints where it abuts a vehicular access crossing layback.[29]
Joints, footpath	Published council examples require joints at intervals of not more than 1.5 m and expansion joints at not more than 18 m; contraction joints formed in plastic concrete to a depth of one quarter of the pavement thickness, aligned at 90° to the pavement and coinciding with kerb joints where possible.[34][32]
Finish	Specified, not chosen. Published examples require smooth steel trowel finish to exposed surfaces with 10 mm radius to exposed corners; smooth trowel to tray and kerb with a sponge finish to the layback; non-slip broom finish retained on dual-use paths.[29][33][32]
Curing	Curing compound, water curing or membrane curing to the governing concrete specification, with prescribed application rates.[12]

The tender-writing point: state the governing tolerance, then state the control that achieves it. “Kerb will be constructed to the R15 tolerance” is a claim. “String line set from survey control at 10 m intervals, checked with a 3 m straightedge before the crew leaves each run, with non-conformance triggering removal and replacement of the affected section at our cost” is a method. Evaluators score the second.

Crystalline silica: the compliance shift that hit concrete hardest

If there is one section of this guide that separates a current concrete works bid from one written three years ago, it is this one.

From 1 September 2024, amendments to the model Work Health and Safety Regulations introduced stronger regulation of work with all materials containing at least 1% crystalline silica. The amendments require controlled processing of all crystalline silica substances, assessment of the risk of work involving that processing, and additional duties where processing is assessed as high risk.^[35] The amending instrument replaced the previous regulations 529A to 529C with a substantially expanded set.^[36]

Concrete is squarely inside the definition. A crystalline silica substance is any material containing at least 1% crystalline silica by weight, and the regulator guidance lists cement, grout, mortar, bricks and pavers among common examples.^[37] Processing is defined to include using power tools or mechanical plant to crush, cut, grind, trim, sand, abrasively polish or drill a crystalline silica substance.^[38]

Now put that next to the specification requirement from earlier in this guide: before excavating and removing existing kerb and channel, saw cut along the existing kerb, footpath, driveway and road pavement.^[6] The specification mandates the activity that generates your worst respirable crystalline silica exposure. Saw cutting, breaking out and grinding concrete is not an incidental part of kerb and footpath renewal — it is the first operation on every work order.

What your tender needs to demonstrate

• A documented risk assessment for CSS processing. Not a line in the SWMS. An assessment that determines whether your processing is high risk, made before the work starts.^[35]
• Controls that make the processing controlled. Water suppression and on-tool extraction for cutting and grinding are the practical mechanisms. Dry cutting concrete without effective dust control is the paradigm high-risk case.
• A silica risk control plan where processing is high risk, accessible to workers before work begins.^[38]
• Training records. Workers involved in high-risk CSS processing, or at risk of exposure because of it, must receive crystalline silica training before commencing. Where processing is not high risk, appropriate information, instruction, training or supervision is still required for anyone who may be exposed. Recognised training includes the nationally coded crystalline silica exposure prevention course and the unit of competency for working with products and materials containing crystalline silica.^[37]
• Air monitoring, and a reporting pathway if the standard is exceeded. The workplace exposure standard for respirable crystalline silica is 0.05 mg/m³ over an eight-hour day. A PCBU carrying out high-risk CSS processing must undertake air monitoring, and exceedances must be reported to the regulator.^[39]
• Health monitoring for workers exposed to RCS in high-risk processes.

Two cautions. First, the model regulations only take effect in a jurisdiction once that jurisdiction implements them in its own WHS laws, and implementation has varied — check with the regulator for each state you work in rather than assuming a single national position.^[35] Queensland, for example, also has a code of practice for managing respirable crystalline silica dust exposure in construction and in the manufacture of construction elements, which its guidance points to for supporting detail.^[38]

Second, this is a cost, not just a document. On a multi-year schedule of rates, silica controls, monitoring and training are recurring overhead attached to every work order. If your rates were set before September 2024 and have not been revisited, they under-recover.

For the surrounding WHS documentation — the plan, the SWMS structure, high-risk construction work notifications — see our WHS management plan and SWMS guide. This section is the concrete-specific overlay on top of it.

Accessibility: footpaths, kerb ramps and vehicle crossings

Footpaths are not just concrete. They are the continuous accessible path of travel, and building one outside compliant grades creates an asset the council cannot accept and a liability nobody wants to own.

AS 1428.1:2021 is the current edition of the general requirements part of the access and mobility series, specifying design detail for continuous accessible paths of travel — widths, heights, passing and turning spaces — along with surfaces, slip resistance, transitions, grates, and ramp and landing gradients.^[31] A note on scope worth getting right, because bidders regularly overstate it: AS 1428.1 is written for new building work and is called up through the National Construction Code in that context. Its application to footpaths in the road reserve comes through the council’s or road authority’s own design standards, which reference the AS 1428 series and set the acceptance criteria your work is measured against — plus the general non-discrimination obligations that apply to public infrastructure.

The requirements that bear on how you build:

• Crossfall. AS 1428.1:2021 requires the crossfall for a walkway or landing to be no steeper than 1 in 40, with a separate and slightly more generous allowance for bitumen surfaces at no steeper than 1 in 33.^[40] Note the direct conflict with drainage: your path has to shed water and stay inside a shallow crossfall limit at the same time. On a renewal where you are tying into an existing kerb at a fixed level and an existing property boundary at another, that is a set-out problem to solve before the pour, not after.
• Longitudinal gradient. Published council specifications commonly set a maximum longitudinal grade for paths — one WA example uses 1:20 — above which the path is classified as a ramp and attracts handrail requirements.^[32] Ramps under AS 1428.1 have their own maximum gradient and landing requirements.^[41]
• Level changes and surface transitions. Abrupt changes at the joint between new and existing concrete are the classic footpath defect. The tie-in detail belongs in your methodology.
• Tactile ground surface indicators. Council standard drawings require TGSIs at locations shown on approved plans in accordance with the relevant part of AS 1428, and finished surfaces to comply with the slip resistance classification standard for new pedestrian surface materials.^[42] TGSI placement at kerb ramps is a recurring non-conformance.
• Grates in the path of travel. Where you are setting a grate into a path or channel, AS 1428.1:2021 limits circular openings and slotted opening dimensions and requires slots to be oriented with the long dimension transverse to the dominant direction of travel.^[43] Getting the orientation wrong is a rework item.
• Vehicle crossings that double as accessible paths. Where a footpath crosses a driveway, the pedestrian grade governs, and the vehicle grade requirements under the parking facilities standard have to be reconciled with it. A crossing designed only to the vehicle profile can defeat the path of travel that runs across it.^[44]

In the tender, treat compliant set-out as a named control with a named responsible person, and say what happens when the existing levels make compliance impossible — because on renewal work they sometimes will. The right answer is a documented notification to the superintendent before the pour, not a non-conforming path and an argument afterwards.

Temporary traffic and pedestrian management

Earthworks happens inside a site boundary. Kerb and footpath renewal happens in a live street, with residents, school children, mobility scooters, bin collection and a footpath you have just removed. Temporary traffic management is not a returnable you attach — it is the operating environment.

The national framework is the Austroads Guide to Temporary Traffic Management (AGTTM), a ten-part guide covering the planning, design and implementation of temporary traffic management, designed to help road authorities meet their legislative responsibilities for workplace and public safety. It applies to all works on or near roads, and its scope expressly extends to protecting vulnerable road users including pedestrians and cyclists.^[45][46]

Three currency points that matter for a 2026 bid:

• The AGTTM has just been substantially updated. Austroads released updated editions of nine parts — Parts 1 to 7, Part 9 and Part 10 — following an earlier update to Part 8, which strengthened the framework for roles, categories, training and accreditation. Changes include revised requirements for traffic management planning, enhanced guidance for different worksite types, additional direction on supervision during training, expanded material on assurance practices, and amendments to sample layouts.^[47] If your traffic management content or your accreditation claims reference the previous editions, update them before you submit.
• AS 1742.3 still sits alongside it. Austroads has published mapping material to help practitioners locate content across the earlier and current editions of AS 1742.3 and the AGTTM.^[45] Cite whichever your tender calls up, and cite the edition.
• Jurisdictions overlay it. Queensland publishes its own Queensland Guide to Temporary Traffic Management, and its guidance is explicit that where an Austroads part cross-references another part, you must refer to the equivalent Queensland part and check its applicability first.^[48] Tasmania adopted the AGTTM with a requirement to also comply with relevant Australian Standards.^[49] In Victoria, councils generally manage road and footpath occupation on local roads while the state department authorises traffic control devices on arterial roads.^[50]

For concrete works specifically, the returnable that earns marks is the pedestrian management component: a pedestrian management plan sitting inside the TMP and shown on the traffic guidance scheme drawings so the crew can set it out exactly.^[50] Address, concretely: how pedestrians get past an open footpath excavation; what you do where there is no verge to detour into; how you maintain property and driveway access while a crossing cures; how you manage school peak times; and who holds which accreditation category on site.

ITPs, hold points, testing and the defects period

Concrete is the work type where quality documentation is least negotiable, because the evidence is destroyed by the next operation. Once the pour is finished you cannot inspect the reinforcement or the subgrade.

Your inspection and test plan for kerb, channel and footpath work should carry, at minimum, hold points at:

• Mix design approval — before any concrete is ordered, against the specified grade and any supplementary cementitious material or low-carbon alternative permitted by the specification.
• Set-out and levels — string line and grade signed off before formwork is fixed, against the accessibility grades and the tie-in levels.
• Subgrade and bedding — after removal of unsuitable material, before bedding is placed, with the depth and compaction of replacement bedding recorded.
• Formwork and reinforcement — before pour, with mesh position and cover recorded where reinforcement is specified.
• Concrete delivery — delivery docket checked against the specified mix on every load, with a rule about added water. Practitioner guidance is blunt about this: no water should be added once the concrete is on site, and if for some reason water is added it should be noted on the batch ticket and reported back to the batch plant.^[51] The corollary is that a non-conforming load can be rejected — write the rejection authority into your ITP so a leading hand knows they have it.
• Sampling and testing — slump and compressive strength cylinders at the specified frequency, through a testing authority holding current NATA registration for the relevant tests, with results forwarded to the superintendent without delay. Our guide to concrete supply, placement and testing covers the pre-pour hold point, curing and what to do when a break comes back low.^[13]
• Finish, joints and curing — finish type, joint formation and spacing, and curing method and application rate recorded before the crew leaves.
• Final survey and tolerance check — straightedge and level check against the governing tolerance, with the non-conformance and rectification path stated.

On a schedule of rates contract, the ITP is not a one-off. It is a per-work-order record, and councils that manage these contracts well audit the records. Show in your bid how the records are captured in the field and how they reach the superintendent — a photograph of a signed paper form on a phone is a system; “records will be maintained” is not.

Two commercial tails to keep in view. First, the defects liability period on a multi-year renewal contract runs on a rolling basis, work order by work order, which means you are carrying defects obligations across the whole term and beyond it. Price for that and resource for it. Second, retention and payment: on a schedule of rates contract your payment claims are made against measured work, and the security of payment regimes apply — see our security of payment guide for the claim mechanics, the timing rules and the retention and trust account regimes state by state.

Where a certified management system is required, the ISO trifecta is usually the gate. Our ISO 9001, 14001 and 45001 guide covers when contract value triggers each one and what certification realistically costs, and the prequalification reference covers the schemes that gate access in each state.

Scoring pitfalls specific to concrete works

Our guide to common tender mistakes covers the general failures. These are the ones that show up specifically on concrete works submissions.

• Writing a project methodology for a program contract. The most common structural error. The tender asks how you will deliver a rolling program of scattered work orders over three years; the response describes how a single street will be built. Answer the question asked: how you receive and schedule work orders, how you sequence a week’s worth of small jobs geographically, how you handle a response defect arriving mid-week, how you resource peak and trough.
• No answer on residential interface. Concrete renewal work happens on people’s frontages. Councils get the complaints. A submission that says nothing about resident notification, driveway access, bin day, or how a damaged garden gets made good is leaving marks on the table in a criterion the council cares about more than you think.
• Silica treated as a generic dust hazard. A SWMS that says “dust suppression will be used” against a specification that mandates saw cutting reads as unaware of the 2024 regulations. Name the assessment, the control, the plan, the training and the monitoring.
• Accessibility mentioned but not engineered. Citing AS 1428 is table stakes. Explaining how you achieve a compliant crossfall while shedding water on a renewal tie-in between fixed levels is the answer that separates bidders.
• Tolerances quoted from the wrong document. Using the road authority tolerance when the council’s AUS-SPEC annexure sets a different one, or vice versa. The annexure prevails.^[27]
• Rates that only work at scale. A schedule priced on 200 m runs, submitted for a contract whose median work order is 15 m. Test your rates against the small end.
• No position on escalation. Submitting a three-year rate schedule without having read the escalation provisions, or without stating your assumption where the tender is silent. If you have assumed fixed rates for the term, say so in your commercial response so it is visible rather than discovered.
• Traffic management as a subcontractor’s problem. The council is asking whether you control the street. Naming a traffic management subcontractor is necessary; showing how their TGS integrates with your daily program and who holds which accreditation is what gets scored.
• Referee projects that are the wrong shape. Three lump-sum subdivision packages do not evidence capability to run a multi-year council renewal program. If your experience is project-shaped, say so plainly and evidence the transferable capabilities — scheduling discipline, small-job productivity, record-keeping — rather than hoping nobody notices.
• A generic capability statement. If your capability statement leads with earthworks plant and bulk excavation experience for a footpath renewal panel, it is working against you. Our capability statement guide covers how to build a version that shifts emphasis by work type.

A pre-submission checklist

Run this before the schedule goes in. Anything you cannot answer is a repricing item, not a footnote.

Commercial

• Contract term and extension options identified, and the rate tested against the full possible duration.
• Escalation provisions located, or their absence confirmed by searching every schedule and annexure.
• If escalation exists: index identified, class assignment for each rate item checked, threshold, cap and base date understood, and symmetry noted.
• Fuel and cartage exposure priced, since it is usually outside the escalation basket.
• Measurement rules read for every item, including where measurement starts and stops on curves and at crossings.
• Inclusions and exclusions reconciled: saw cutting, demolition, disposal, bedding, reinstatement, traffic control, testing.
• Minimum work order value or small-quantity rate confirmed, or requested in clarifications.
• Quantity-variation and no-guaranteed-volume clauses read; exclusivity position confirmed.
• Contract form identified and its variation, EOT and provisional sum mechanics understood.
• Rates stress-tested against the smallest plausible work order, not the average.

Technical

• Governing specification identified — council AUS-SPEC version including its annexure, or the road authority specification and edition.
• Concrete grade, thickness, reinforcement, joint spacing, finish and curing requirements taken from that document, not from memory.
• Tolerances stated with the control that achieves each one.
• Standard drawings checked for kerb profiles, crossing types and pram ramp details.
• Accessibility grades reconciled with drainage, and the notification path for non-compliant existing levels stated.
• TGSI and slip resistance requirements addressed.
• ITP with hold points at mix design, set-out, subgrade, reinforcement, delivery, testing, finish and final survey.
• NATA-registered testing authority nominated and the fee in the rate.

Compliance and returnables

• Crystalline silica risk assessment, controls, risk control plan where applicable, training records, air monitoring and health monitoring arrangements — for the jurisdictions the contract covers.
• WHS management plan and work-type-specific SWMS for concrete cutting, breaking out, formwork and placing.
• Traffic management plan and pedestrian management plan, referencing the current AGTTM editions and the relevant jurisdictional guide.
• Traffic management accreditation categories held by nominated personnel, current.
• Environmental controls, including concrete washout, slurry containment from wet cutting, and stormwater protection at the very drainage inlets you are working on.
• Resident notification and access management process, in writing.
• Insurances at the required limits, prequalification current, and every mandatory returnable in the schedule ticked off individually.

One last observation, offered as a commercial judgement rather than a rule. Multi-year concrete schedules are among the most valuable contracts a small civil business can hold — predictable, local, repeatable, and a foundation for everything else you bid. They are also the contracts where a single mispriced rate compounds for three years without any of the corrective mechanisms a lump-sum job gives you. The time to get it right is before the schedule is submitted, because after award the rate is the rate.
