3Setting up the project

3.1Start dates

Where a project is delayed by more than 28 days of the estimated start date of program of works provided by the client, Wardle Construction has the right to refuse the client agreement.

Where a project is delayed by more than 28 days of estimated start date of program of works, Wardle Construction has the right to revisit the quote price.

Any project with an estimated start date greater than 3 months from the quote issue date will be revisited 28 days from project start date.

3.2Site

The client agrees Wardle Construction will have access to the site Monday to Friday 6:30am to 3:30pm excluding public holidays, unless alternative times are agreed prior to project start date.

On occasion it may be necessary to work outside of the nominated DA hours in order to complete concrete finishing.

The client agrees to provide:

• Access to toilet facilities and wash area.
• Edge protection, handrail, barriers and scaffolding. Wardle Construction will supply and install edge protection to the first slab level only (not exceeding 3.0 m above adjacent ground level, and only where formwork is able to be extended as a walkway, not when brickwork is the edge). For any work above 3.0 m, the client must provide a compliant edge-protection or scaffolding plan, including slab edges and wall perimeters.
• Complete survey setout including grids and datums as required as in the set-out and levels section.
• A secure, locked compound or storage container will be made available for storing materials and tools.
• The client is liable for security of the site and its contents.

Wardle Construction agrees to keep the site clean and tidy while completing services.

The client will ensure Wardle Construction has clear and uninterrupted site access.

3.3Waste management

The client agrees to provide adequate waste management facilities, skip bins and similar, for the disposal of any leftover reo, off cut timber and plywood as required.

Wardle Construction agrees to minimise usage of the client waste management facilities as much as possible.

Surplus materials are to be discarded into the client's waste facilities where needed.

3.4Fittings and exposures

The client agrees to accept sole responsibility to protect fittings or exposures prior, during and post Wardle Construction being on site.

Wardle Construction does not accept any responsibility for any damages where the client has not provided adequate protection for fittings or exposures.

3.5Internal inspections and readiness requirements (ITP)

• Pre-start: Checklist released 7 business days pre-start; site walk 2 business days pre-start.
• Pre-steel: QC and safe-loading or logistics review.
• Pre-pour: Final QC, safety and logistics gate.

Evidence and extra visits: If pre-start items are not complete, the client must supply clear photos with written confirmations.

Not ready: Wardle Construction may pause or reprogram until issues are rectified. Standby, re-mobilisation and supplier fees apply.

Notice: If the site will not be ready, the client agrees to advise in writing with 24 hours notice so dates can be adjusted.

Limitation: These inspections are for Wardle Construction's internal QA only and do not replace statutory, engineer or certifier inspections. The client retains responsibility for overall compliance, coordination and approvals.

3.6Plans information (client to supply)

Required documents: A single, coordinated Issue-for-Construction (IFC) package comprising the latest documents reflecting the works to be carried out. Outdated or non-conforming drawings will not be accepted or used. The most current set of documents shall be signed by both parties upon acceptance of the conforming tender quotation.

• Structural IFC (engineer-approved), and Architectural IFC matching the Structural;
• Relevant specs and schedules (rebates, openings, finishes, waterproofing interfaces).

Format: PDF (and DWG where available). Hand sketches, scribbles, marked-up emails or verbal directions are not acceptable for pricing or construction.

The client is responsible for proof reading plans to ensure structural and architectural details match. See the variations during works section.

Coordination and precedence: Structural governs; Architectural must match in RLs and FFLs, gridlines, dimensions, openings and rebates. Window and door rebates must appear on Structural and match Architectural; conflicts excluded or treated as variations.

3.7Pre-start plan changes (between agreement and start)

Notify in writing: Any change to Structural or Architectural drawings or specs made after the client agreement is signed and before mobilisation, the client agrees to notify Wardle Construction in writing with updated, clouded IFC drawings (rev and date), and a brief written instruction. Verbal changes on site will not be accepted; all changes must be documented via revised documents or sketches which are then subject to repricing.

Variation only: These changes are excluded from the contract sum and proceed only as an approved variation. No documents results in no pricing and no proceed. Variation only, with updated clouded IFC and written instruction.

Timing and program: Pricing and lead-time starts when the complete pack is received. Changes notified within 5 business days of the planned start may require reprogramming; EOT, standby, return-visit and remobilisation may apply per the Schedule of Rates.

4During the project

4.1Site management and supervision (client foreman required)

The client agrees to provide a full-time foreman or site manager on site whenever Wardle Construction and its suppliers are present; absence may pause works; EOT, standby and remobilisation apply.

The client agrees the foreman or site manager to be competent, inducted and authorised to: issue written instructions, coordinate trades, access, permits and traffic control, sign daily dockets, timesheets and deliveries, approve minor clarifications, and make immediate decisions during set-out, pour and strip.

Absence or unavailability (including phone-only supervision) may result in Wardle Construction pausing works until supervision is restored. Time lost will extend the program (EOT) and standby, return visit and remobilisation charges apply per the Schedule of Rates.

The client's foreman is responsible for client-controlled safety systems (scaffold, edge protection, platforms), public protection and traffic control, set out, and for verifying site readiness against Wardle Construction's pre-start and pour-day checklists.

4.2Set-out and levels, responsibilities and process

4.2.1 The client (primary control and top-side set-out). The client agrees to and accepts responsibility for providing and maintaining full set-out: gridlines, control points and benchmarks, RLs and FFLs, slab edges, rebates and set-downs, wet areas, wall lines, hobs and upstands, steps, stairs and risers, penetrations and openings, pour breaks and construction joints.

4.2.2 Documents and changes. The client agrees to ensure all set-out aligns to the coordinated IFC (Structural and Architectural). Any change requires updated, clouded drawings (rev and date). No documents results in no proceed.

4.2.3 Survey timing. Ground floor: the client agrees to provide gridlines and survey before commencement. Each subsequent level: the client agrees to provide updated gridlines and survey after the previous pour and before the next level starts.

4.2.4 Wardle Construction (formwork soffit control only). Wardle Construction agrees to set out formwork to slab soffits, beam sides and form folds only, built from the client's primary control. The client agrees to accept responsibility for all other set-out. Wardle Construction agrees to build to the client's marks; any request for top side or finishes set out by Wardle Construction is a variation.

4.2.5 Verification and consequences. The client agrees to, prior to steel fixing or pour, check and sign a set-out verification for items under the client's scope. The client agrees that errors, omissions or missing control that cause rework, delay or return visits are chargeable per the Schedule of Rates.

4.2.6 Payment. The client agrees to ensure payment of invoices within 14 days. Wardle Construction agrees to provide progress invoices from project start date until project completion. Any payments not made within 14 days of due date of invoice will incur a 5% surcharge. Any payments not made within 28 days of due date of invoice will incur an additional 5% surcharge. All payment claims are made under the Building and Construction Industry Security of Payment Act 1999 NSW.

4.3Variations during works (last-minute)

Definition: A last-minute variation is any change on the day, after set-out has started, including after steel placing.

4.3.1 Instruction (written only). Email or signed site instruction only. Verbal or onsite chats are not accepted.

4.3.2 Minimum requirements (attach to every request).

• Marked plan or sketch (PDF or DWG) with clouded changes and rev and date.
• Dimensions and levels: sizes, depths, RLs and FFLs, set-downs and rebates.
• Location and extent: gridlines, level, room or bay, quantities.
• Brief description of the change.

4.3.3 Pricing basis and proceed rules. Wardle Construction will price only from the minimum requirements. Response clock starts when complete minimum requirements are received. Incomplete minimum requirements will result in RFI and no proceeding. Approved last-minute variations may attract EOT, reprogramming, standby and return-visit costs as per the Schedule of Rates.

4.3.4 Rates and charges (urgent works). Charged at urgent, daywork or cost-plus per the Schedule of Rates, including supervision, plant, pump and cranage standby, overtime, re-set and re-mobilisation, restocking and waste. Minimum call-out and time blocks apply as per the Schedule of Rates. Delivery and lead-time constraints may apply.

4.3.5 Program and safety. Affected works may pause until written approval and complete documentation are received. Safety-critical measures may proceed immediately; pricing to follow.

4.3.6 Site differs from Structural IFC. If site conditions do not match the Structural IFC used for quoting, Wardle Construction agrees to notify the client in writing promptly and issue a variation price and time impact. If not approved, the client agrees to make the site compliant with the Structural IFC before works continue. Related standby, reprogramming and return costs will be charged as per the Schedule of Rates.

4.3.7 Wardle Construction agrees to. As soon as practicable, advise estimated cost and program impact for the requested change in writing. Notify if the variation is likely to affect the date for completion and provide an EOT assessment in writing.

4.4In-ground works

It is the responsibility of the client to ensure:

• Excavation to slab edges be a minimum of 300mm from slab edge to install edge boards, if not possible concrete will be poured up to the excavated area.
• Excavation to beam widths to be a minimum of the width dimensions shown on plans.
• Excavation to beam depths to be minimum of the depth dimensions shown on plans.
• Excavation to underside of the slab to be a minimum of the depth dimensions shown on plans.
• Vertical faces to excavation to have precautions taken, if needed, to prevent collapsing into the beams.
• Supply and installation of shoring or sacrificial (lost) formwork required for earth retention to detailed excavations, fill-as-form, compacted fill, or any area shown as fill on the Structural drawings is excluded from Wardle Construction's scope and is the client's responsibility.
• Any over excavation to depths of slabs and beams by more than 50mm will be the client's responsibility to supply and install blinding or ancillary items such as larger bar chairs to accommodate.
• Any extra concrete supply needed due to over excavation will be added on top of the given allowance for that section. Charged as per the Schedule of Rates.
• Excavation, piles and piers to be cleared of all debris and water.
• Excavation and blinding to be completed prior to Wardle Construction beginning works.
• Plumbing to ground slabs to be finished prior to Wardle Construction beginning works unless agreed to prior.

Once works have commenced, any required excavation or hand digging is the client's responsibility. The client agrees, if Wardle Construction is requested to excavate, it will constitute a variation charged as cost plus as per the Schedule of Rates. The client agrees to request this in writing.

4.5Concrete finishes

All finishes and measure tolerances per NSW Guide Section D and AS 3610.1.

4.5.1 Concrete finishing tolerance, slabs. Flatness: 4 mm or less in any 2 m length. Levelness (RL and FFL): 10 mm or less within any room or area; 20 mm or less overall footprint.

4.5.2 Concrete finishing tolerance, vertical. Finish class: as noted on drawings (AS 3610.1). If not noted, Class 3. Flatness (3 m straightedge): Class 1 3 mm or less; Class 2 5 mm or less; Class 3 10 mm or less. Out-of-plumb (3 m gauge): Class 2 5 mm or less; Class 3 10 mm or less. Deviation from RL at tops and soffits: plus or minus 10 mm at nominated control points. Finish concrete as per specifications prescribed within the documents listed within this proposal.

4.6Concrete pour days, client responsibilities and pumper dump

4.6.1 The client agrees to:

• Provide a clear, unobstructed area prior to the pour for the pump and supply trucks (staging, turning and lay-down as required).
• Provide traffic control and permits: obtain any traffic control and permits required by authorities and email proof to Wardle Construction.
• Nominate and maintain an area for concrete blow-out.
• Nominate a safe, clear area for surplus concrete.
• Dispose of surplus concrete.

4.6.2 Pumper dump allowance (per scheduled pour), if this option is included in tender. Included: one pumper dump is included with each scheduled concrete pour. Extra pours: every additional or return pour requires one additional pumper dump (charged per the Schedule of Rates). Credit (opt-out): if not needed or provided by others, a credit of the included allowance will be applied only if requested in writing before the pour. Opt-out consequences: if directed not to provide a pumper dump, the client accepts full responsibility for blow-out and waste, removal of surplus concrete, disposal fees, and site clean-up. Pumper dump is for washout and blow-out only, not general disposal. Regardless of pumper dump, the client is responsible for any surplus, spill or washout on site.

4.6.3 Concrete delivery vehicles, access and damage allocation. Wardle Construction is not liable for any damage, subsidence, cracking, spalling, rutting, broken pipes or services, or contamination caused by concrete delivery vehicles (agitators, pumps, auxiliary trucks) on or off site. The client agrees to plan and maintain access routes, obtain permits and traffic control, and provide surface protection suitable for vehicle loads. All make-good, clean-up, disposal and third-party claims from vehicle movements are at the client's cost. If Wardle Construction books at the client request, Wardle Construction acts as agent only. Where tight access, traffic control or permits prevent delivery, the client agrees to pay for returned concrete and associated cartage, disposal, abort, re-booking and standby. Charges are priced case-by-case at actual supplier rates plus Wardle Construction's costs, or per the Schedule of Rates where applicable. Hose ramp or bridge (public crossing): if required, the client agrees to provide, install, maintain, and remove or make good any hose ramp or bridge where the concrete pipeline or hose crosses public access. Permits and traffic control by the client.

4.6.4 Concrete strength testing (by request). Not included in the quote unless requested in writing. Testing by NATA lab on request with 2 or more business days notice; charged at supplier and lab rates and Wardle Construction's costs. Includes sample collection, cylinder making, and lab breaks (for example 7 and 28 days). If requested inside 2 business days, best efforts only; call-out and urgent fees may apply.

4.6.5 Concrete curing. Default: the client accepts responsibility for water-based curing of all concrete horizontal (slabs and flatwork) and vertical faces (walls, columns, edges) by continuous wetting or ponding or wet hessian under plastic, for the period required by the spec or engineer. Curing compound (by request): if requested in writing before the pour, Wardle Construction can apply an agreed curing compound as a priced variation. No written request: curing reverts to water curing as the responsibility of the client. Compatibility: where a curing compound is requested, the client is responsible for selecting a compatible curing compound with subsequent finishes, adhesives and coatings.

4.6.6 Structural repairs (Wardle Construction scope only). Where structural integrity is affected (for example honeycombing, blowouts, voids, exposed reinforcement), Wardle Construction agrees to repair to restore structural capacity using approved materials and methods and, where required, to the structural engineer's direction. Acceptance of repairs is based on structural integrity, not aesthetic appearance. Coil tie holes: patching or plugging of coil and through-tie holes is not included in Wardle Construction's fixed price. If requested, Wardle Construction can perform this on a cost-plus basis per the Schedule of Rates.

4.7Concrete pour cancellations

If a concrete pour is delayed or aborted due to insufficient space or access or missing permits or traffic control, the client agrees to pay wait fees, aborted-pour charges, return cartage, and re-booking fees, priced case-by-case at actual supplier charges and Wardle Construction costs.

4.7.1 Notice to cancel. Cancellations must be made in writing (email or SMS to the nominated contact) 24 or more hours before the booked start time (arrival of first truck or pump). No cancellation fee applies, however any non-recoverable third-party costs already incurred may be charged at cost. Priced case-by-case based on actual supplier charges and Wardle Construction's costs incurred.

4.7.2 Cancellations under 24 hours. If a pour is cancelled within 24 hours of the booked start time, the client is liable for charges as per the Schedule of Rates, including as applicable: concrete supplier cancellation and return fees (including minimums and special-order materials); pump, crane and plant call-out, stand-down and demobilisation; labour minimums and standby; redelivery and remobilisation.

4.7.3 Aborted pour or on-site cancellation. If cancellation occurs after dispatch or on site, charges apply for aborted pour, wait time (billed per the Schedule of Rates), return fees, wastage and disposal, and rebooking.

4.7.4 Extreme weather. In the rare circumstance where unpredictable extreme weather (for example heavy rain, high winds, lightning, excessive heat) directly affects safe placement or quality, Wardle Construction may postpone or abort the pour. In such cases the client is responsible for wait time, aborted pour and rebooking costs per the Schedule of Rates and any supplier charges prevailing at the time. Wardle Construction will act reasonably to minimise costs, including calling off prior to dispatch where practicable.

4.7.5 Authority to postpone or abort. Either Wardle Construction or the client's nominated representative may postpone or abort the pour where extreme weather is likely to affect safety or quality. If the client's nominated representative requests to continue pour in adverse weather then full responsibility for weather related defects is with the client.

4.7.6 Rebooking and availability. Rebooking is subject to availability. Any out-of-hours or accelerated rebooking requested by the client will be charged per the Schedule of Rates. Priced case-by-case based on actual supplier charges and Wardle Construction's costs incurred.

4.8Brickwork and blockwork

The client agrees to ensure that all brickwork and blockwork is correct heights as on plans. Supply and install of slip joints are not included in our pricing.

The client agrees that any brickwork or blockwork not at the correct RL that requires extra formwork (for example aprons or turndowns) will be charged on a cost plus basis. Block filling and block outs are not included unless requested at tender.

4.9Materials and logistics

Materials provided in quote may be subject to a price increase where the quote has been accepted more than 28 days past the issue date. The client may request written evidence of price increase from the supplier.

Materials unable to be retrieved from site due to the client or other trades will be payable by the client as per the Schedule of Rates.

Any material paid for by Wardle Construction that is not used due to default or cancellation is payable by the client including steel and concrete.

Supply of materials is calculated on Structural and Architectural drawings and SoW provided.

The client agrees there may be additional cost incurred by the client if services are delayed due to interrupted site access; this includes access to material lifts and lift shafts where applicable.

Wardle Construction is not liable for any damages or defects caused by other trades to any work Wardle Construction has completed.

The client agrees that if a project is delayed, Wardle Construction may need to demobilise to another project. The client will incur a $1,500 demobilisation fee and a $1,500 reestablishment fee.

Material handling and lifting, formwork: Wardle Construction has allowed for horizontal handling on the working level only. Any vertical movements to or from other levels (stairs, shafts, hoists, crane lifts) are the client's responsibility (provide labour, cranage or hoist).

Material handling and lifting, steel reinforcement: Wardle Construction has allowed for steel reinforcement lifting to ground level only. Any lifting to or from other levels is the client's responsibility (additional labour or cranage).

Cranage and traffic management: If required, cranage can be organised by Wardle Construction on a case-by-case basis, cranage at supplier rates and Wardle Construction costs. The client accepts responsibility for all permits, traffic control, road occupancy and like requirements.

4.9.1 Crane assumption, verification and upgrades. Assumption: cranage is not ordinarily allowed for unless requested at tender stage. Wardle Construction will deliver all materials and off load onto agreed materials of load zone and will only distribute materials horizontally. Any vertical movement shall be carried out by crane or hand labour at the client's expense. Where cranage is requested to be included in our price, the quotation will clearly state the cranage allowance, including the number of lifts (the lift allowance), and assumes a crane with nominal 24m reach. Final crane selection is subject to on-site verification by the crane supplier (access, set-up, load, radius, obstructions, ground conditions and load charts). If site conditions prevent use of a 24m reach crane (for example greater radius, heavier lifts, obstruction clearance, limited set-up area) and an alternative configuration is required (larger crane, fly jib, additional counterweights, different set-up location, extra crew or rigging, road occupancy or traffic control), the client accepts responsibility for all additional costs and will be charged separately per the supplier charges.

4.10Weather

4.10.1 Fixed-price works. The client agrees that in the case of extreme weather that directly impacts on the ability to work on site, these days will automatically be added to the services completion date at no additional charge to the client.

4.10.2 Cost-plus works. In the case of extreme weather that directly impacts on the ability to work on site, these days will automatically be added to the services completion date; all attendances arising from the event, including standby and wait time, securing and protection, demobilisation and remobilisation, are charged on a cost-plus basis per the Schedule of Rates. Minimum call-out and shift charges and any minimum labour and plant charges apply.

4.10.3 Formwork stripping. Formwork stripping schedules are as follows as a guide unless specified by engineer prior to the client agreement being signed:

• Vertical faces, walls, columns, edge boards: 1 day following concrete pour.
• Horizontal faces, suspended slabs: 7 days following concrete pour.
• The client is responsible for supplying any propping design prior to contract execution.
• Engineer-certified propping and back-propping design by the client pre-contract; if absent, it reverts to 2 to 3 m centres, max 28 days from pour (assumption only).
• Coil tie cones stripped on day of stripping or if requested to leave in, then they are the responsibility of the client to remove.

If the client requires specific time commitments to stripping, the client agrees to provide the request in writing.

4.11Off-form works, finish class, acceptance and responsibilities

4.11.1 Standard and finish class. Off-form concrete finishes are to AS 3610.1 (Formwork for concrete, specifications). Class 1 is not offered by Wardle Construction. Class 2 (architectural fair-faced) is the agreed finish for visible surfaces and will be delivered on a cost-plus basis. Boarded off form (board-marked) is the agreed finish for visible surfaces and will be delivered on a cost-plus basis.

4.11.2 Acceptance, inherent imperfections. The client accepts that off-form concrete will exhibit inherent imperfections permitted by the nominated class under AS 3610.1. For Class 2 surfaces, minor blemishes are acceptable, including small bug holes, slight honeycombing, colour and tonal variation, faint form and joint lines, minor grout loss at joints and corners, and other minor surface marks consistent with the standard. For boarded off-form surfaces, acceptable characteristics include small bug holes, minor grout loss at joints and corners, faint paste bleed at board joints, and slight tonal banding. All timber boards are to be supplied by the client, including species, grade, thickness, moisture content and clean, straight, and fit for purpose. Timber used for boarded off form needs to be approved by Wardle Construction prior to using if Wardle Construction is installing the boards. Any upgrading beyond the nominated class (for example skim or patch to achieve a higher aesthetic) is excluded and will be at the client's cost.

4.11.3 Mock-up and test panels, Class 2 OFC and boarded OFC. Use, retention and costs: where practicable, the mock-up will be incorporated into the permanent works to reduce cost. If incorporation is not feasible, the mock-up will be delivered as temporary works on a full cost-plus basis. Temporary mock-ups will be removed and disposed of at the client's cost on completion. Requirement and timing: before starting works, Wardle Construction agrees to construct one mock-up test panel representative of the final finish. Location to be agreed on site. Complete the mock-up 5 or more working days before the first stage to allow review. Scope of mock-up: includes formwork system, face and board module, tie-hole layout, panel and joint set-out, construction joint or shadow line rebate type, steel type (galvanised or black), release agents and wetting, concrete mix, placement and vibration method, curing method, and proposed weather protection. Submission and records: provide a short method statement (materials, mix, steel type, release, wetting, compaction, curing, protection, strip times) and photos of the completed mock-up. Inspection and acceptance: inspect at approximately 3 m viewing distance under diffuse daylight (no raking light); benchmark panel governs assessment. Acceptance covers overall colour and texture, joint and tie alignment, arrises and bug-hole frequency and size consistent with Class 2 or boarded. Reality check: exact colour and texture uniformity is not guaranteed; boarded patterns are not invisibly patchable, any future repairs remain perceptible. Benchmark status: once accepted, the mock-up becomes the benchmark. Subsequent work will be assessed by reasonable comparison to this benchmark plus the project tolerances and finish class. Change control: any change after approval (mix design, form face, release, curing, board species or grade, tie layout, protection) requires written re-approval and, if material, a new mock-up (variation on a cost-plus basis).

4.11.4 Galvanised steel supply and applications. Galvanised steel is supplied only where explicitly specified on the issued-for-construction drawings or specifications or requested in writing prior to contract signing. If not triggered, supply defaults to black or mill-finish steel in accordance with the relevant base standards. Lower maintenance and defect risk: utilising galvanised steel reduces early remedial cleaning and patching of off-form faces caused by rust leachate. Good use cases for galvanised steel: external and off-form walls, planters and garden beds, soffits with wind-driven rain, podium slabs, coastal projects, splash zones, or anywhere off-form finish quality is critical to the client.

4.11.5 Weather protection and risk allocation. The client agrees to supply, install and maintain effective weather protection from formwork erection until handover or application of subsequent finishes. The client is responsible for protection to prevent rain and run-off, direct sun and heat, wind-borne debris, staining and uneven curing. The client accepts that failure to maintain weather protection can materially and irreversibly affect final quality and appearance (for example colour variation, mottling or staining, efflorescence, crazing, surface dusting, visible pour lines or blowholes). Where protection is not maintained, all resultant defects, rework and delay costs are the client's responsibility. Wardle Construction is not liable for aesthetic non-conformance arising from exposure. If requested prior to formwork installation, Wardle Construction can provide temporary protection on a cost-plus basis on a case by case basis.

4.11.6 Repairs, patching and skimming (Class 2 off-form and boarded off-form). Acceptance within finish class: imperfections compliant with the nominated AS 3610.1 finish class are deemed acceptable. The client accepts responsibility for any cost associated with any patching or skimming to improve aesthetics beyond the nominated class. Concrete aftercare (sanding): if required, sanding or abrasion to remove rust or water staining and minor surface imperfections is the client's responsibility. Where black steel is used, early remedial cleaning or sanding of rust-leachate staining on off-form faces is expected and is the client's responsibility. The client accepts responsibility and cost for any aesthetic patching (third-party specialist, client scope). All off-form and aesthetic patching and finishing is to be carried out by a third-party specialist contractor engaged by the client. This includes, without limitation: tie-hole treatment, bug-hole filling, grout rubs, colour, tonal and texture matching, arris and joint line tidying, minor grout loss at joints and corners, skim and fairing coats and similar works. Boarded off-form: where a board pattern is specified or visible, the client agrees Wardle Construction is not responsible for reinstatement of board grain and joint lines. Weathering and site damage: repairs required due to weathering or other site-caused damage are by the client. If Wardle Construction is instructed to rectify, the works will be treated as a variation on a cost-plus basis. These works are not included in Wardle Construction's fixed price or scope. Tender contingency: the client must allow a contingency in their tender for the third-party off-form patching and finishing described above, including boarded off-form reinstatement and any aesthetic upgrades beyond the nominated class.

4.11.7 Changes to finish class. Any change to the nominated finish class (for example Class 3 to Class 2, or a bespoke higher aesthetic) must be requested in writing and will be priced as a variation, including any additional protection, methodology, mock-ups and inspection or hold points.

4.12Pricing and methodology (cost-plus)

4.12.1 Commercial basis. All off-form concrete works are performed strictly on a cost-plus basis under the Schedule of Rates. No cap or fixed sum applies unless expressly stated in the contract.

4.12.2 Items priced as lump sum (quantifiable inputs). Wardle Construction will provide a fixed price (lump sum) only for items that are readily quantifiable at tender stage, typically: formwork materials supply; reinforcement supply; concrete supply; concrete pump; concrete finishing; steel fixing labour (where measured). For boarded off-form, all timber boards are to be supplied by the client, including species, grade, thickness, moisture content and clean, straight, and fit for purpose.

4.12.3 Items priced as cost-plus (variable delivery and labour). The following are supplied cost-plus and charged at actuals per the Schedule of Rates: formwork labour (delivery and handling, installation and adjustments, stripping and demobilisation, removal from site); supervision and coordination of Wardle Construction works and interface with other trades; attendances (standby, waiting time, rebooking, make-safe, temporary protection).

4.12.4 Estimates, not fixed. For the cost-plus portion, Wardle Construction will provide an estimate of man-hours for planning purposes. This is an estimate only and is not a fixed price. Invoices will reflect actual hours.

4.12.5 Drivers that may vary actual hours or cost. Actual man-hours may vary due to factors outside Wardle Construction's control, including but not limited to: missing, late or changed details (updated drawings, unresolved RFIs, or absent specifications); rain or extreme weather and related safety or quality hold-offs; other trades (out-of-sequence works, rework, access conflicts, site damage); access and logistics (crane or lift availability, lift shafts, lay-down constraints, materials not staged); the client readiness (site not 100% ready to commence, inspection delays, hold points); program changes (re-sequencing, call-offs, partial pours).

4.12.6 Records and verification. Cost-plus charges will be supported by daywork dockets and timesheets. Wardle Construction will keep daywork dockets and timesheets for all cost-plus work, detailing labour start and finish times, location and brief description of works. Dockets will be signed on site by the client's representative. End-of-day sign-off: the client agrees that the client's site representative will review and sign the docket or timesheet at the end of each day (physical or electronic signature). A signed docket or timesheet is final and conclusive evidence of the hours, resources and charges for that day and is not subject to later dispute. No sign-off available: if the client's representative is unavailable or fails to sign on the day, Wardle Construction will issue the docket or timesheet for signature on the next working day. If no written query is received within 1 business day, the record is deemed accepted.

4.12.7 Minimum charges, same-day stop of cost-plus work. If cost-plus work is stopped or suspended on the day for any reason (for example weather, access, RFI or design hold, other trades, the client instruction), minimum shift charges apply. Shift start reference: standard shift start is 7:00am. Minimum charges (per worker and mobilised plant item): stop before 11:00am, 4 hours charge; stop between 11:00am and 1:00pm, 6 hours charge; stop at or after 1:00pm, 8 hours (full day) charge. Standby and wait time prior to a stop decision is chargeable per the Schedule of Rates. Minimums apply regardless of the cause of the stoppage, except where stoppage is solely due to Wardle Construction's default.

4.13Off-form concrete, design drawings, defaults and cost impact

The client-supplied design (pre-contract): The client agrees to provide coordinated off-form concrete design drawings before contract execution, showing at a minimum:

• Panel and joint set-out and dimensions.
• Formply sheet sizes and orientation.
• Coil and through-tie pattern and spacing.
• Corner, edges and any intricate design features.

Pricing basis and variations: If the above information is not provided prior to contract (or is later revised), the pricing will be adjusted: fixed-price items may be re-priced; and cost-plus labour will be charged at actual hours, which may differ from estimates.

Default assumptions for quoting (no drawings provided): Where no off-form drawings are provided at the time of quote, pricing assumes sheet pattern of 1.2 m by 1.8 m formply and tie pattern at 600 mm centres each way. Any departure from these defaults will be treated as a variation.

4.14Burnished or polished concrete slabs, finishes, tolerances and risk

Definition, polished concrete (mechanically polished): slab or topping mechanically ground, honed and polished, with densifier or hardener; gloss or matt and aggregate exposure to be nominated. All mechanical polishing (grind, hone, polish), densifier, hardener and guard, sealants and coatings, edge polishing, joint filler installation and edge dressing for polish, test panels and final clean are excluded from Wardle Construction's scope and will be performed by a third-party specialist engaged by the client.

Definition, burnished finish: steel-trowelled finish to achieve sheen with minimal grinding or honing. Wardle Construction's scope ends at placement and steel-trowel finish of the slab or topping to the tolerances specified elsewhere (flatness and levelness). Any remedial grinding, re-profiling or re-finishing to satisfy the polishing system is by the polisher; if Wardle Construction is directed to assist, it is a variation on a cost-plus basis.

Substrate requirement (topping vs structural slab): Where a polished or burnished finish is required as the final floor, a dedicated topping slab (nominally 75 to 100 mm unless engineered otherwise) is to be used as the wearing surface.

The client is responsible for the design, supply and installation of all construction, control and isolation joints in topping slabs, including layout, detailing and materials, to the structural engineer's, the architect's and where applicable the polisher's written requirements and relevant Australian Standards.

If no topping slab is provided and the structural slab is nominated as the finished surface, the client acknowledges the finish standard will reduce materially due to reduced control over level and flatness, joints, curl, reinforcement cover, and finishing conditions. Colour and tonal variation, trowel marks, differential sheen and telegraphing of construction joints are expected.

Structural slab as finished surface (no topping): Burnished or polished appearance will vary; uniform sheen and colour are not guaranteed. Any mechanical grinding, re-profiling or levelling required to remove high spots or achieve plane or levels suitable for finishing is by the client's third-party polisher and at the client's cost, including any consequential patching and sealing.

Protection and risk: From handover to the polisher, protection of the slab (traffic, staining, water ingress, trades damage) is the client's or polisher's responsibility. Damage or discolouration occurring after handover is not Wardle Construction's defect.

4.15Defects, notification, assessment and rectification

Flow: 1. Log. 2. Inspect and evidence. 3. Responsibility (RFI if needed). 4. Plan (ours) or variation (not ours). 5. Execute. 6. Sign-off. 7. Close-out. 8. Dispute: joint inspection. 9. Independent assessor (50/50).

4.15.1 Log the defect. Notice of defect: the client agrees to notify Wardle Construction in writing with location, photos, and spec or drawing references before any rectification is undertaken.

4.15.2 Inspect and evidence. A site inspection is required to verify the defect and gather evidence (photos, measurements, tests). If information is unclear, Wardle Construction will issue an RFI and assessment pauses until resolved.

4.15.3 Determine responsibility. Assessed against IFC Structural and Architectural, SoW, approved variations, and agreed tolerances and standards and all Wardle Construction ITP. If information is unclear, Wardle Construction issues an RFI; assessment pauses until resolved.

4.15.4 Rectification path or plan. Wardle Construction defect: Wardle Construction agrees to issue a defect-rectification plan (scope, method, program, access needs). Works proceed at Wardle Construction's cost. Not Wardle Construction's defect: Wardle Construction issues a variation offer (scope, time, price; no admission of liability). If declined, the client arranges others.

4.15.5 Execute rectification. Works completed per the agreed plan.

4.15.6 Third-party rectification (pre-approval required). Rectification by the client or others is at the client's risk and cost unless the subcontractor has approved in writing the scope and cost before commencement. Unapproved costs are not recoverable from Wardle Construction.

4.15.7 Acceptance and sign-off. Joint inspection on completion using Wardle Construction's defect close-out checklist. The client provides written acceptance (email or site sign-off). Acceptance is per the agreed rectification scope (structural vs cosmetic as applicable).

4.15.8 Close-out report. Issued by Wardle Construction: defect reference, cause assessment, method and materials used, before and after photos, test results and sign-off.

4.15.9 Dispute resolution. If disputed, joint inspection first. If unresolved, appoint an independent assessor mutually agreed; fees shared 50/50. The assessor's written recommendation informs responsibility and cost allocation for final resolution.

4.15.10 Aesthetic acceptance (off-form work). Visual acceptance is by reasonable comparison to the approved mock-up or benchmark and the nominated AS 3610.1 finish class. Cosmetic upgrades beyond the nominated class are excluded unless approved as a variation.

4.15.11 No cross-project set-off or retention. Amounts payable under this subcontract must not be withheld, set-off or retained to satisfy claims or alleged defects on any other project or contract, unless expressly agreed by deed.

4.16Delays, program of works and charges

Continuity assumption and short-notice rule: Wardle Construction prices assume continuous, uninterrupted work in line with the client's program. Any works cancelled, postponed or deferred with less than 1 week's notice may incur delay damages (see waiting and hold-up fees and stand-down and remobilisation).

4.16.1 Delays to start of project. When the start moves due to client-side causes (info or approvals, access or permits, preceding works), Wardle Construction will extend the program by the delay period and reprogram dates. If the start is pushed by 28 days or more, Wardle Construction will use best endeavours to lock in a new start window; however, the new date is not guaranteed and is subject to availability, external constraints, and clashes with other committed projects. If the original slot is reallocated, the project will be re-slotted to the next available window after intervening commitments are completed.

4.16.2 Delays between staged work. Where sequencing becomes stop-start, only partial areas are released, or extra return visits are required beyond the agreed program, Wardle Construction will extend and reprogram the works. Wardle Construction will use best endeavours to accommodate revised stage dates; however, revised windows are not guaranteed and remain subject to availability and clashes with other committed projects. Charges apply for return visits and remobilisation and additional set-out and supervision. Changes with less than 1 week's notice may attract delay charges.

4.16.3 Delays during works (once started). If, after commencement, issues arise, for example late or conflicting IFC or approvals, unresolved RFIs, non-compliant scaffold or edge protection, late services penetrations, or design changes and other trades after set-out, Wardle Construction may pause the affected area until resolved; the program will move accordingly. Supplier charges for pump, truck and crane standby, abort, return and re-booking are recoverable at actual supplier rates. Responsibility of the client.

4.16.4 Waiting and hold-up fees. Labour (per person, per hour): formworker, concrete finisher, steel fixer, leading hand, supervisor. Minimum if a shift is lost: 4 hours. Standard shift start 7:00 am. Minimum time bands (per worker and mobilised plant): stop before 11:00 am, charge 4 hours; stop 11:00 am to 1:00 pm, charge 6 hours; stop at or after 1:00 pm, charge 8 hours (full day). Notes: standby and wait time before a stop decision is chargeable at the Schedule of Rates. Minimums apply regardless of cause except where stoppage is solely due to Wardle Construction's default. Supplier plant and logistics (typical): concrete pump standby (per hour) line $276.75, boom $384.75 (supplier minimums apply); agitator waiting (per truck) $4.81 per minute (approximately $288.60 per hour) per supply dockets; Wardle Construction HIAB standby $200 per hour (minimums apply); items not in the Schedule of Rates are case-by-case at actual supplier rates and Wardle Construction costs (evidence provided).

4.16.5 Stand-down and remobilisation. Stand-down (when redeployment is not feasible): $1,500 per standard working day. Remobilisation and return-visit fees: crew re-establishment $650 per crew plus travel. New dates will be confirmed in writing; availability is not guaranteed and remains subject to calendar clashes and external constraints. Notice and mitigation (all sections): Wardle Construction will notify delay events with likely time and cost impacts and use best endeavours to mitigate. Where mitigation is not feasible, the program moves, and the fees above apply.

4.16.6 Suspension (non-payment). If any properly invoiced amount is not paid, Wardle Construction may suspend work by written notice and remain suspended until cleared funds are received. On payment, the suspension is lifted. The suspension period extends the program (EOT) and Wardle Construction may re-set dates without penalty.

4.16.7 Dispute resolution. If a dispute cannot be resolved within 2 business days, the parties will attend mediation in good faith. Mediation costs are shared 50/50. Any agreed outcome will be recorded in writing and is binding. Non-payment: if a client does not agree to mediation and withholds payment without Wardle Construction's approval, Wardle Construction will issue a letter of demand after 28 days. Following the letter of demand, any unpaid invoices will be referred to a debt collector, with all associated debt collection fees being the responsibility of the client.

4.16.8 Contract termination. The client termination for breach: the client may terminate by written notice if Wardle Construction commits a material breach and, where capable of remedy, fails to commence and diligently pursue remedy within 3 days of written request. Wardle Construction termination for breach or non-payment: Wardle Construction may terminate services if the client fails to pay within 3 days of the payment due date on a payment schedule or the client commits a material breach. Damages fee on termination: if the contract is terminated for any reason other than Wardle Construction's unremedied material breach, the client must pay the greater of 10% of the remaining balance or $2,000 as a damages fee, in addition to amounts due for work performed and committed costs.

4.18Client responsibilities

4.18.1 Program, documents and instructions. Program of works: issue a baseline program (start and finish, staging, milestones and hold points) before mobilisation and update promptly when dates change. Wardle Construction prices on continuous, uninterrupted access; changes with less than 1 week's notice may attract delay charges. Coordinated IFC set: provide engineer-approved Structural IFC and matching Architectural IFC (clouded changes with rev and date). Ensure RLs and FFLs, gridlines, dimensions, openings and rebates align. Window and door rebates must appear on Structural IFC and match Architectural. Set-out and surveys: provide gridlines and benchmarks, set-out, and surveys for each level; confirm structural slab and finished floor heights including steps, stairs and risers. Variations (written only): requests must include the minimum requirements: marked PDF or DWG (clouded), dimensions, RLs and FFLs, location and quantities, description, and updated clouded IFC. No documents means no proceed. Variations are accepted only in writing. Propping and back-propping design (the client): the client must provide an engineer-certified propping and back-propping design (drawings plus notes) pre-contract. If absent, Wardle Construction will price and program on the assumption only of back-propping to slabs at approximately 2.0 to 3.0 m centres each way, maintained for a maximum of 28 days from the pour date. This assumption is not an engineered design and is used solely for pricing and programming. Any requirement tighter than 2.0 to 3.0 m, longer than 28 days, or any certification or inspection is excluded and will be treated as a variation. Engineer directions, if issued later, supersede the assumption.

4.18.2 Access, safety and temporary works. Scaffold and edge protection: provide compliant scaffolding, handrail, safety-rail, platforms, access and egress. Edge protection beyond one slab level (approximately 3 m) is the client's responsibility. Wardle Construction will only provide handrails to formwork leading edges, to a maximum of 3 m in height. Wardle Construction will not erect handrails to perimeter brick or block walls or the like. Safe vertical access is to be provided to all suspended floors exceeding 3 m; permanent access is to be provided by the client once the formwork is completed. Wardle Construction will provide temporary access during the erection of formwork and is to only be used by Wardle Construction staff. No other personnel other than Wardle Construction staff shall access the formwork deck whilst under construction. Traffic control and permits: arrange TCP, ROLs and permits and email proof to Wardle Construction 2 or more business days pre-pour. No proof results in no proceed; reprogramming and costs may apply. Pump and crane setup and staging: provide clear, unobstructed areas for pump and supply trucks (staging, turning, lay-down) and notify any adverse site conditions that may hinder access or pumping. Hose ramps and bridges: where pump lines cross public, pedestrian or vehicle paths, supply, install and maintain a rated hose ramp or bridge with signage and controls.

4.18.3 Pour-day logistics, surplus, clarifications and pumper dump. Parking and standing: arrange parking and standing for concrete agitators and pump trucks prior to pour day. If no parking is available for the pump and agi and pour is cancelled the client is liable for all associated cancellation costs. Blow-out and surplus areas: nominate a safe blow-out or washout area and a separate surplus-concrete area on site. Surplus concrete: manage and dispose of all surplus concrete, regardless of pumper dump use. Pumper dump: one unit may be included per scheduled pour under the quote if stated. Extra or return pours require additional units. Written opt-out pre-pour means credit of the allowance; if opted out, the client assumes all waste, removal and clean-up. The client agrees to establish and confirm all required concrete levels and finishes with the Wardle Construction supervisor and shall be documented in Wardle Construction pre-pour checklist. The client and Wardle Construction agree to confirm that the correct concrete mix has been ordered and delivered prior to the dispatch of the first agi. The client agrees to confirm that all related trades have been advised of the concrete pour and that they are responsible for any of their in-slab services, and that Wardle Construction is not responsible for any damage that may occur to their in-slab services.

4.18.4 Curing, protection and concrete aftercare (by client). Curing (default): water curing by the client to all horizontal and vertical faces unless Wardle Construction is requested in writing to apply a curing compound (variation; the client is responsible for finish compatibility). Protection: protect existing finishes during works and concrete finishes after strip; weather-proof exposed ply, formwork and finishes (tarps or temporary roofing). Aftercare: perform light sanding or abrasion to remove staining and surface imperfections and sealing, polishing or coatings as required; product selection, compatibility and maintenance sit with the client. Expected outcomes: black steel, early rust-leachate cleaning or sanding to off-form faces is expected and by the client; flush construction joints (no rebate), visible line or minor leakage is expected, not a defect, the client to patch if desired.

4.18.5 Testing, inspections and readiness. Concrete testing: not included unless requested in writing; can be arranged per pour (charged at lab and supplier rates plus Wardle Construction costs where not in the Schedule of Rates). Pre-start and site inspections: comply with Wardle Construction's pre-start readiness checklist; provide photo evidence and ensure items are complete 2 or more days before start. If not ready, reprogramming, standby and return-visit fees may apply. Daywork dockets: ensure daily sign-off of timesheets and dockets; signed records are conclusive for that day, subject to fraud or manifest error notified within 1 business day.

4.18.6 Risk, damage and cost recovery. Concrete delivery and pumping, third-party and access liability: any damage to public or private property, roads, kerbs, footpaths, driveways, landscaping, services or structures arising from concrete delivery trucks, agitators, pump trucks, lines or washout is the sole responsibility of the concrete supplier or pump operator that caused it. However, where damage arises from or is aggravated by access issues under the client's control, including insufficient or unsafe access or staging, non-load-rated or unprotected surfaces, inadequate traffic control or permits, or directions on routing or positioning, liability rests with the client for that portion and any resultant costs. Returned concrete: if delivery or placement fails due to access, traffic control or permit issues, the client pays for returned concrete and related supplier charges (return cartage, disposal, abort, short-load and minimums, re-booking) plus Wardle Construction costs where applicable. Waste and environmental: provide and maintain environmental controls and manage all concrete waste on site.

4.18.7 Levels, masonry and excavation. Brick and block heights: ensure blockwork and brickwork matches plan heights before Wardle Construction works. Heights and levels: provide correct structural and finished floor heights including steps, stairs and risers; Wardle Construction is not liable for make-good if incorrect information is issued. Excavation: complete all excavation, including any required hand digging, and subgrade or working platform preparation unless expressly included in Wardle Construction's scope.
