The goal is simple: reduce surprises, protect cashflow, and make sure the scope they think they are buying is the scope they will actually get.
What exactly is included in this HPAS package, line by line?
They should get a full inclusions schedule, not a brochure summary. An HPAS specialist should be able to point to every item that is included, where it is specified, and what brand, model, rating, or allowance applies.
They should ask for a signed, version-controlled document that lists fixtures, finishes, engineering, energy compliance, certification, and any site works. If something is “standard,” it still needs to be written down.
What is excluded, and what will trigger a variation?
Exclusions are where budgets often blow out. An HPAS expert should state exclusions in plain language, then explain the exact events that cause a variation, plus how variations are priced and approved.
They should confirm whether the contract uses fixed rates, builder margin percentages, and admin fees on variations. They should also ask how long variation pricing remains valid, especially when trades are busy across Australia.
What assumptions have been made about the site conditions?
Most packages assume an “ideal” site. A good HPAS expert will list site assumptions such as soil classification, fall across the block, rock removal, access for machinery, stormwater connection points, and existing services.
They should ask what happens if the soil test returns reactive clay, deep fill, or unexpected rock. They should also confirm whether bushfire, flood overlays, coastal corrosion zones, or termite risk change the design and cost.
What reports and tests are needed before the price is truly fixed?
They should ask which investigations are required to convert estimates into firm costs. An HPAS expert should be clear on when they need a contour survey, geotechnical report, BAL assessment, and dial-before-you-dig checks.
They should also confirm whether service location, stormwater legal point of discharge, and driveway crossover approvals are needed before signing. In many councils, these details can materially change the scope.
Which Australian standards and NCC requirements does the design comply with?
They should not accept “it meets code” without specifics. An HPAS expert should confirm compliance with the National Construction Code (NCC), relevant Australian Standards, and local planning rules for the state or territory.
They should ask who is responsible for energy efficiency (NatHERS) targets, ventilation, waterproofing compliance, termite management, and smoke alarm placement. They should also ask how compliance evidence will be documented for handover.
Who owns the design, and can they change it later without penalties?
Design ownership affects flexibility. An HPAS expert should explain whether the buyer owns the plans, whether they can take them to another builder, and what fees apply for revisions.
They should ask what “free” design changes really means, including how many rounds are included and whether changes reset approvals. If they think they might adjust layouts later, they should clarify the cost and time impact now.
What is the build timeline, and what events extend it?
They should ask for a realistic programme, not an optimistic promise. An HPAS expert should provide estimated dates for approvals, site start, slab, frame, lock-up, and practical completion.
They should also ask what extends time under the contract, such as wet weather, supply shortages, industrial action, client selections delays, and variation approvals. They should confirm whether liquidated damages apply if the builder runs late.
What deposit and progress payment schedule applies, and is it compliant?
They should confirm the deposit cap and progress stages that apply in their state, because these vary across Australia. An HPAS expert should explain the payment triggers, including what evidence is provided at each stage.
They should ask whether progress claims are linked to actual completion milestones, independent inspections, or certificates. They should also ask how disputes over stage completion are handled, and whether they can withhold payment for incomplete work.
Which contract is being used, and can they review it before paying anything?
They should ask for the exact contract form early, not at the last minute. An HPAS expert should state whether it is an HIA or MBA contract, or a bespoke agreement, and what special conditions are added.
They should ask for time to get independent legal advice. They should also ask where key terms sit, including variation clauses, delay clauses, prime cost items, provisional sums, termination rights, and dispute resolution steps.
Are there prime cost items or provisional sums, and how risky are they?
Allowances create uncertainty. An HPAS expert should list every prime cost item and provisional sum, plus the allowance amount and what it is meant to cover.
They should ask whether the allowances match realistic retail pricing in their city or region. If a kitchen, tiles, or electrical is under-allowed, they should treat the base price as marketing, not a true cost.
What selections are included, and what happens if they miss deadlines?
Selections drive both cost and delays. An HPAS expert should provide a selections schedule with deadlines for colours, cabinetry, appliances, tapware, flooring, and lighting.
They should ask what happens if a product is discontinued or delayed, and whether substitutions require approval. They should also confirm whether late selections trigger extension of time claims or admin fees.
Who is responsible for permits, approvals, and inspections in their council area?
Responsibility gaps cause painful delays. An HPAS expert should confirm who lodges development applications, building permits, and any required engineering, and who pays each fee.
They should ask how the builder handles council requests for information, neighbour notifications, and conditions like stormwater detention. They should also ask who books mandatory inspections and who attends, especially if private certifiers are involved.
How will communication work, and who is their day-to-day contact?
They should know who answers questions when issues appear on site. An HPAS expert should outline the project team structure, including a supervisor, client liaison, and escalation path.
They should ask how often they will get updates, what channel is used, and how decisions are recorded. Email trails and variation portals matter, because verbal agreements rarely protect anyone.
What warranties, insurances, and protections apply in their state?
They should confirm what protection they actually have, not what they assume exists. An HPAS expert should explain builder insurance, public liability, and home warranty insurance where applicable.
They should ask about statutory warranties, defects liability periods, and what is required to make a warranty claim. They should also confirm how insolvency risk is managed and what documents they will receive at handover.
Can they see recent local projects and speak to past clients?
They should ask for proof, not promises. A credible HPAS expert should be able to provide addresses or case studies for recent builds in the same state, ideally in similar site conditions.
They should ask to speak with past clients about budget accuracy, variation frequency, communication quality, and defect rectification. If references are cherry-picked, they should request a broader sample.
What quality controls and independent checks are recommended?
They should ask how quality is verified beyond basic inspections. An HPAS expert should explain internal checklists, trade sign-offs, and how defects are tracked.
They should also ask whether independent inspections are welcomed at slab, frame, waterproofing, and pre-handover stages. If the builder discourages independent checks, that is useful information before signing.
What are the likely “gotchas” in this specific package?
They should ask the uncomfortable question directly. An HPAS expert should be able to name the common surprises for that product and location, such as site costs, driveway and landscaping exclusions, stormwater upgrades, or acoustic requirements for attached dwellings.
They should ask for a written “risk list” with dollar ranges. Even rough ranges help buyers plan contingencies, especially when construction markets tighten in Australia.
What should they do next before signing anything?
They should request a final, consolidated pack: inclusions, exclusions, allowances, site assumptions, timeline, and the exact contract version. An HPAS expert should encourage independent review, because good deals survive scrutiny.
They should also keep a short checklist: confirm approvals pathway, confirm fixed versus allowance items, confirm variation rules, and confirm who pays for what. If those are clear, signing becomes a decision, not a gamble.
Before they sign, the smartest move is to treat every promise as a document request. The right HPAS expert will not just answer questions quickly; they will make sure the answers are measurable, written, and enforceable.
FAQs (Frequently Asked Questions)
What exactly is included in an HPAS package and how can I get a detailed inclusions schedule?
An HPAS expert should provide a full inclusions schedule that lists every item included line by line, not just a brochure summary. This document should be signed, version-controlled, and specify fixtures, finishes, engineering details, energy compliance, certifications, and any site works. Every ‘standard’ item must be clearly documented with brand, model, rating, or allowance details.
What are common exclusions in HPAS packages and how do variations affect the budget?
Exclusions often lead to budget overruns. An HPAS expert will clearly state what is excluded in plain language and explain what events trigger variations. They should clarify how variations are priced and approved, including whether fixed rates, builder margin percentages, or admin fees apply. It’s also important to know how long variation pricing remains valid amid busy trade schedules across Australia.
How do site condition assumptions impact the HPAS package scope and cost?
Most HPAS packages assume ideal site conditions. A knowledgeable expert will list assumptions about soil classification, block fall, rock removal needs, machinery access, stormwater connection points, and existing services. They should explain what happens if tests reveal reactive clay, deep fill, or unexpected rock and confirm if bushfire zones, flood overlays, coastal corrosion areas, or termite risks alter design or costs.
Which reports and tests are necessary before finalizing the HPAS package price?
Before fixing the price firmly, investigations such as contour surveys, geotechnical reports, BAL assessments (for bushfire risk), and dial-before-you-dig checks are typically required. An HPAS expert should specify these requirements and confirm whether approvals for service locations, stormwater discharge points, and driveway crossovers are needed prior to contract signing since these can materially change the project scope.
How does the HPAS design comply with Australian standards and the National Construction Code (NCC)?
An HPAS expert will confirm specific compliance with the NCC relevant to your state or territory as well as applicable Australian Standards and local planning rules. They should clarify responsibilities for energy efficiency (NatHERS) targets, ventilation requirements, waterproofing compliance, termite management strategies, smoke alarm placement, and explain how compliance evidence will be documented at handover.
Who owns the design in an HPAS package and can changes be made later without penalties?
Design ownership affects flexibility; an HPAS expert will explain whether you own the plans outright and if you can take them to another builder. They will detail fees for revisions including what constitutes ‘free’ design changes—such as how many rounds are included—and whether changes reset approvals. If you anticipate adjusting layouts later on, clarifying potential cost and time impacts upfront is essential.
