| Critical | Livable Housing Design / AS 1428.1 - ramps (verify) | Flags ramps steeper than the configured maximum gradient of 1:14. | Entry ramp #700006 | Ground | 1:11 | ≤ 1:14 | Reads the ramp's own gradient. It does not check landings, handrails or the total rise across a series of ramps. |
| Critical | AS 1657 - guardrailing (verify) | Flags plant and walkway guardrails whose readable height is below the configured minimum of 900 mm. | Balustrade - stair #700003 | Level 1 | 840 mm | ≥ 900 mm | Reads the railing type's height parameter. It says nothing about openings between rails, or whether a guardrail exists where one is required but none is modelled. |

| Major | ABCB Housing Provisions 2022 NT 13.5.2(1), NT Table 13.5.2 | Flags habitable rooms in a climate zone 1 project whose total ventilation opening area, as a fraction of floor area, is below the minimum for a room without a ceiling fan or evaporative cooler. | Bed 3 #700008 | Level 1 | 3.1% of floor area | ≥ 5% of floor area | Assumes 50% of window glazed area is openable, since the model does not record actual window hardware; treat a Fail as needing verification against the window schedule. This threshold applies only where no ceiling fan or evaporative cooler serves the room and the project is in climate zone 1 - lower thresholds apply where a fan or cooler is fitted, which this check cannot detect. Also does not evaluate the alternative compliance path of ventilating via an adjoining room's opening. |
| Major | ABCB Housing Provisions 2022 NT 13.5.2(1), NT Table 13.5.2 | Flags habitable rooms in a climate zone 3 project whose total ventilation opening area, as a fraction of floor area, is below the minimum for a room without a ceiling fan or evaporative cooler. | Bed 3 #700010 | Level 1 | 3.1% of floor area | ≥ 5% of floor area | Assumes 50% of window glazed area is openable. Applies only where no ceiling fan or evaporative cooler serves the room and the project is in climate zone 3 - lower thresholds apply otherwise, which this check cannot detect. Does not evaluate the adjoining-room ventilation path. |
The model could not decide these. Most of the Code is about materials, ratings, certification and procedure that no geometry carries, so each one names what would settle it. They are work for a person, not defects.
| Area | Clause | Requirement | Element | Level | Observed | Required | What would settle it |
|---|---|---|---|---|---|---|---|
| acoustics | NCC 2022 Vol One Part F7 / Housing Provisions Part 10.7 | Raises sound insulation as a single item to confirm. | Whole building #700032 | - | needs confirmation | - | Confirm there is test evidence or an acoustic assessment for every wall and floor separating sole-occupancy units. Ratings come from tested assemblies where material, thickness and insulation act together, so a wall's modelled thickness cannot show compliance. |
| energy | NCC 2022 Vol One Section J / Housing Provisions Section 13 | Raises the building's energy efficiency obligation as a single item to confirm. | Whole building #700029 | - | needs confirmation | - | Confirm which compliance pathway this project uses - a NatHERS certificate, a JV3 or whole-of-home assessment, or the elemental provisions - and that it covers the design as currently modelled. Note that some inputs to it are specification decisions rather than assessment outputs: roof and wall solar absorptance comes from the finish selected and its data sheet, and it changes which insulation R-Value the tables require. |
| fire-resistance | NCC 2022 Vol One Sections C and Specifications | Raises fire-resisting construction as a single item to confirm. | Whole building #700030 | - | needs confirmation | - | Confirm the type of construction, and that every element required to have a fire resistance level has evidence of one. An FRL is a property of a tested system, so nothing in the model can show it. |
| fire-services | NCC 2022 Vol One Part E1 | Raises fire fighting services as a single item to confirm. | Whole building #700031 | - | needs confirmation | - | Confirm that sprinklers, hydrants, hose reels and extinguishers are provided where required, against the fire services design. These are usually in a linked services model, so their absence here does not mean they are absent from the building. |
| structure | NCC 2022 Vol One Section B / Housing Provisions Sections 2 to 6 | Raises structural adequacy as a single item to confirm. | Whole building #700033 | - | needs confirmation | - | Confirm the structural design and certification cover the building as modelled, including footings sized for the site classification and framing for the wind classification. Structural adequacy needs loads and materials, not shapes. |
| waterproofing | NCC 2022 ABCB Housing Provisions 10.2.2 | Raises NCC 2022 ABCB Housing Provisions 10.2.2 as an item to confirm, because the model cannot decide it. | Whole building #700039 | - | needs confirmation | - | Check the shower waterproofing detail and specification against Figure 10.2.2 to confirm floor, wall, junction and penetration treatment matches the shower type modelled (enclosed, unenclosed or preformed base). |
| waterproofing | NCC 2022 ABCB Housing Provisions 10.2.3 | Raises NCC 2022 ABCB Housing Provisions 10.2.3 as an item to confirm, because the model cannot decide it. | Whole building #700040 | - | needs confirmation | - | Check the wet area detail drawings and waterproofing specification for the area outside the shower to confirm floor and wall/floor junction treatment matches the flooring material used. |
| waterproofing | NCC 2022 ABCB Housing Provisions 10.2.4 | Raises NCC 2022 ABCB Housing Provisions 10.2.4 as an item to confirm, because the model cannot decide it. | Whole building #700041 | - | needs confirmation | - | Check the wet area detail drawings and waterproofing specification for the bath or spa recess to confirm floor, wall and junction treatment matches the vessel type (freestanding, non-freestanding or inserted) shown in Figure 10.2.4a/10.2.4b. |
| waterproofing | NCC 2022 ABCB Housing Provisions 10.2.5 | Raises NCC 2022 ABCB Housing Provisions 10.2.5 as an item to confirm, because the model cannot decide it. | Whole building #700042 | - | needs confirmation | - | Check the wet area detail drawings and waterproofing specification to confirm wall, floor and junction treatment around each vessel, and in laundries, WCs and WCs fitted with a handheld bidet spray, matches Figure 10.2.5 and the extents set for each case. |
| waterproofing | NCC 2022 ABCB Housing Provisions 10.2.6 | Raises NCC 2022 ABCB Housing Provisions 10.2.6 as an item to confirm, because the model cannot decide it. | Whole building #700043 | - | needs confirmation | - | Check the waterproofing specification to confirm the nominated waterproofing system is documented against either the waterproof materials in 10.2.8, or the water resistant substrate and surface materials in 10.2.9 and 10.2.10. |
| waterproofing | NCC 2022 ABCB Housing Provisions 10.2.7 | Raises NCC 2022 ABCB Housing Provisions 10.2.7 as an item to confirm, because the model cannot decide it. | Whole building #700044 | - | needs confirmation | - | Check the waterproofing specification to confirm every wet-area material is listed against the waterproof materials in 10.2.8 or the water resistant materials in 10.2.9. |
| waterproofing | NCC 2022 ABCB Housing Provisions SA 10.2.1 | Raises NCC 2022 ABCB Housing Provisions SA 10.2.1 as an item to confirm, because the model cannot decide it. | Whole building #700036 | - | needs confirmation | - | Check the wet area detail drawings and waterproofing specification to confirm treatment around washing machine tap outlets, inset kitchen or bar vessels, and floor wastes matches SA Figures 10.2.1a to 10.2.1c and AS 3740. |
| waterproofing | NCC 2022 Vol One Part F2 / Housing Provisions Part 10.2 | Raises wet area waterproofing as a single item to confirm. | Whole building #700034 | - | needs confirmation | - | Confirm the wet area details show membranes, falls and junctions to the required extents. These are finishes and detailing, which a model does not carry as measurable elements. |
| weatherproofing | NCC 2022 Vol Two NSW 4.2.8 | Raises one item asking whether the slab-on-ground damp-proofing membrane meets the specified material (thickness, impact resistance, branding) and installation detail (laps, service-penetration sealing, puncture repair). | Whole building #700035 | - | needs confirmation | - | Confirm against the slab damp-proofing membrane specification and the slab pour inspection/hold-point record. |
| weatherproofing | NCC 2022 Vol Two SA 4.2.8 | Raises one item asking whether the slab-on-ground damp-proofing membrane meets the specified material (thickness, impact resistance, branding) and installation detail (laps, service-penetration sealing, puncture repair). | Whole building #700037 | - | needs confirmation | - | Confirm against the slab damp-proofing membrane specification and the slab pour inspection/hold-point record. |
Every change the tool made or was told about, with the value it replaced and who was at the keyboard. The same record is written into the Revit file, so it travels with the model.
