Size and plan airport sanitary facilities across terminal zones using applicable codes and occupancy-driven fixture counts.
A parametric airport sanitary planning tool for early-stage terminal planning, enabling architects, planners, and engineers to estimate sanitary fixture requirements, accessible facilities, and planning areas using internationally recognized codes and airport-specific methodologies.
{*Applicable Standards*}[D8431E]
• {*NBCS 2026 (India)*}[9BAB20] – Occupancy-based sanitary fixture calculations for Indian projects.
• {*International Codes (IBC + NFPA 101)*}[9BAB20] – Occupancy-based planning using internationally recognized building and life safety standards.
• {*ACRP Guidebook*}[9BAB20] – Airport-specific methodology using Peak Hour Passengers (PHP) and aircraft demand.
{*Calculation Methodology*}[D8431E]
1. {*Select*}[9BAB20] the applicable calculation standard.
2. {*Define*}[9BAB20] terminal zones and enter occupancy or passenger demand inputs.
3. {*Review*}[9BAB20] or modify occupancy factors where permitted.
4. {*Configure*}[9BAB20] planning parameters such as Gender Split, Accessible Toilet Ratio, and Male Fixture Distribution (ACRP only).
5. Click {*Update Model*}[2F47AC] to calculate occupant loads or peak hour passengers, sanitary fixture requirements, accessible facilities, and planning areas.
Results are generated as a {*read-only planning schedule*}[2F47AC], providing fixture counts, accessible facilities, and estimated toilet block areas for each terminal zone. The calculations are intended for {*conceptual planning*}[2F47AC] and {*capacity assessment*}[2F47AC] rather than detailed architectural design.
{*Key Assumptions*}[D8431E]
• Occupancy factors are derived from the selected standard unless manually overridden.
• ACRP calculations are based on {*Peak Hour Passenger (PHP)*}[9BAB20] methodology.
• {*Accessible Stalls*}[9BAB20] within toilet blocks and {*Accessible Toilets*}[9BAB20] are calculated independently.
• Fixture planning areas represent conceptual design modules and include circulation allowances.
• Final layouts, plumbing design, accessibility compliance, and statutory approvals should be verified during detailed design.
{*Scope Note*}[D8431E]
This tool is intended for {*feasibility studies*}[2F47AC], {*early design*}[2F47AC], and {*optioneering*}[2F47AC]. Results are based on the selected methodology, user-defined inputs, and planning assumptions, and should be validated against project-specific requirements before statutory submission.
