📋 Compliance Summary
🚪 Findings by Category
Doorways & Openings
✅
Main entry — clear door width 960mm
Measured clear width of 960mm exceeds the minimum 850mm required for accessible entry. Door hardware appears operable from a closed fist position.
✅
Internal doors — clear width 860mm (Level 1 corridor)
All Level 1 internal doors meet the 850mm minimum clear width requirement. Approach clearances appear adequate based on plan dimensions.
❌
Service room door — clear width 720mm, below minimum
Service room on Ground Floor shows a clear door width of approximately 720mm. This does not meet the 850mm minimum required for accessible routes. Widening to minimum 850mm clear width is required.
Corridors & Circulation
✅
Ground floor corridor — width 1,500mm
Primary corridor exceeds 1,200mm minimum for continuous accessible path. Passing spaces appear adequate throughout.
⚠️
Level 1 east corridor — width narrows to 1,100mm at column
Plans indicate a narrowing at structural column location, reducing corridor to approximately 1,100mm. This may not provide adequate passing space. Review with structural drawings to confirm and consider widening or providing an accessible bypass route.
Ramps & Gradients
✅
Entry ramp — gradient 1:16
The external entry ramp shows a gradient of 1:16, compliant with the 1:14 maximum gradient for ramps. Handrails appear on both sides per specifications.
❌
Internal ramp (Level 1 connection) — gradient 1:10, exceeds maximum
The internal ramp connecting the north wing to the Level 1 gathering area shows a gradient of 1:10. This exceeds the maximum permissible gradient of 1:14. This ramp is on the accessible path of travel and must be redesigned to comply.
⚠️
Car park access ramp — gradient not dimensioned on plan
The accessible car park access ramp gradient is not noted on the submitted plans. If this forms part of the accessible path of travel, gradient confirmation is required. Provide dimensioned gradient on updated plans.
Accessible Toilet Facilities
✅
Ground floor accessible toilet — floor area and clearances appear compliant
The designated accessible toilet compartment dimensions of 1,900mm × 1,600mm meet minimum requirements. A 900mm clear space at the side of the pan appears indicated, and a 1,800mm turning circle appears achievable.
❌
Level 1 accessible toilet — door opens inward, blocking required floor clearance
The Level 1 accessible toilet door appears to swing inward on the plan. An inward-swinging door will obstruct the required 900mm side clearance and turning circle. The door must be respecified as outward-swinging or sliding to maintain required floor clearances.
⚠️
Grab rail positions not shown on toilet plans
Specifications do not include grab rail layout drawings for either accessible toilet. AS 1428.1 prescribes specific grab rail positions, heights, and load ratings. Provide grab rail layout plan for both facilities for review.
Tactile Ground Surface Indicators
✅
Main entry — tactile indicators shown at kerb ramp
Directional and warning TGSI appear to be indicated at the kerb ramp approach to the main building entry, consistent with AS 1428.4.1 requirements.
❌
Internal stair landings — no tactile indicators shown
Plans do not show tactile ground surface indicators at the top and bottom landings of the internal staircase. Warning TGSI are required at both stair approaches. Add warning TGSI as noted in AS 1428.4.1 Cl. 5.2.
Handrails
✅
External entry ramp handrails — both sides, height noted at 900mm
Handrails shown on both sides of the external ramp at a height of 900mm, within the required 865–1,000mm range. Top rail graspable profile appears appropriate.
⚠️
Handrail extensions at stair head and foot — not shown
Plans do not clearly indicate horizontal handrail extensions at the top and bottom of the internal staircase. AS 1428.1 requires a minimum 300mm horizontal extension past the last riser. Confirm and annotate on plans.
Accessible Parking
✅
3 accessible car spaces provided — compliant with NCC D3 ratio
For a public assembly building of this scale, 3 accessible bays from a total of 85 spaces satisfies the NCC D3.4 provision requirement. Shared access aisle of 2,400mm shown between bays.
✅
Accessible bays located within 50m of accessible building entry
Accessible parking bays appear within the required proximity to the accessible entry. The path of travel from bays to entry is on a level surface based on site plan dimensions.
Signage
✅
International Symbol of Access shown on accessible toilet doors
Plans indicate accessible toilet signage on both Ground and Level 1 facilities using the ISA symbol. Mounting height appears within required range.
✅
Accessible parking bay signage — ISA shown on plans
International Symbol of Access noted on all 3 accessible parking bays per plan legend. Raised-profile floor markings also indicated.
🔧 Required Actions (5 items)
1
Widen service room door to minimum 850mm clear width
Current 720mm clear width is non-compliant. Revise door and frame schedule to achieve minimum 850mm clear. Confirm approach clearances at the revised opening.
AS 1428.1 Cl. 5.3.2
2
Redesign internal Level 1 ramp to maximum 1:14 gradient
The 1:10 gradient exceeds the maximum permissible for ramps on an accessible path of travel. Revise the ramp geometry to achieve 1:14 or flatter. Confirm that all associated landing dimensions remain compliant after redesign.
AS 1428.1 Cl. 8.1 / NCC D3D10
3
Change Level 1 accessible toilet door to outward-swinging or sliding
An inward-swinging door obstructs required floor clearances within the accessible toilet. Specify an outward-swinging door or sliding door to maintain the 900mm side clearance and 1,800mm turning circle.
AS 1428.1 Cl. 15.1
4
Add tactile ground surface indicators at internal stair landings
Warning TGSI are required at the top and bottom approach of all internal staircases. Update plans to indicate TGSI strips at both stair approaches in accordance with AS 1428.4.1 Cl. 5.2.
AS 1428.4.1 Cl. 5.2
5
Provide grab rail layout drawings for both accessible toilets
Grab rail positioning, heights, and load ratings must be specified and shown in plan. Provide a detailed toilet fitout drawing for both facilities. Ensure all grab rails meet AS 1428.1 Cl. 15.4 requirements including 600N load rating and 32–50mm graspable diameter.
AS 1428.1 Cl. 15.4
🤖 AI Expert Analysis
Generated by AccessLens AI
Overall assessment: The Riverdale Community Centre plans demonstrate a reasonable intent toward accessible design, with several elements — notably the main entry, external ramp, parking provisions, and Ground Floor toilet — meeting compliance requirements. However, five non-compliant findings require design changes before the project can be considered fully compliant with the DDA Premises Standards and NCC Part D3.
Priority items: The two most critical issues are the Level 1 internal ramp gradient (1:10 vs. the required maximum 1:14) and the inward-swinging accessible toilet door on Level 1. Both are on primary accessible paths of travel and affect the usability of the building for wheelchair users. The ramp in particular may require a significant geometry change — the design team should assess whether an alternate layout can achieve the required gradient within the available floor area, or consider a platform lift as an alternative.
Documentation gaps: The absence of grab rail drawings and confirmation of the car park ramp gradient are documentation issues rather than likely design failures. These should be straightforward to resolve with supplementary drawings. Addressing the Level 1 corridor narrowing at the column will require confirmation from structural drawings and, if the 1,100mm dimension is confirmed, a design resolution — either a wider opening or an accessible bypass route.
Recommendation: Address the five required actions before DA lodgement. Items 3–5 can likely be resolved through specification updates and supplementary drawings. Items 1 and 2 require architectural redesign and should be resolved in consultation with the project architect and structural engineer before next plan submission.
