Defined focal point / activity area
LUTHVAR · SPECTATOR PLANNING CENTRE
Capacity is a geometry problem before it becomes a seat count.
Use this centre to test early row count, seat-centre, row-depth and footprint assumptions, then work through sightlines, accessibility, egress, structure, covers and operations before the exact spectator system is released.
CONCEPT CAPACITY CALCULATOR
Expose the assumptions behind the stand.

Not an egress, accessibility, sightline, guard, structural or code-compliance calculation. Final configured capacity is determined by the project layout and local professional review.
SIGHTLINE INPUT CHECK
Do not choose the rake before the focal point is known.
Good spectator geometry requires a project-specific section through the actual field/court/stage, barrier, first row and seating bowl. These are the inputs the project team should close.
First-row eye position
Row depth
Riser height
Seat/eye offset
Barrier / guard geometry
Standing spectators / front-row conditions
Accessible viewing positions
Canopy columns / roof edges
Displays / cameras / railings
SYSTEM-SPECIFIC CHECKS
Steel grandstand
Confirm the focal point and spectator eye line before selecting rake/riser geometry.
Coordinate aisles, vomitories, stairs, guards, handrails, accessible routes and companion seating with the destination code and appointed designer.
Capacity follows the configured seating layout; nominal seat count is not a substitute for an egress/accessibility review.
Foundations, reactions and structural design remain project-specific.
SPECTATOR WORKFLOW
Capacity → sightlines → access → structure → exact system.
That order is deliberate. Selecting a seat or grandstand family before the geometry is understood creates rework.
Venue + target capacity
Focal point + sightline section
Rows / aisles / accessible positions
Egress + circulation review
Structure / foundations / covers
Exact seat / stand / retractable system
Submittals, installation boundary + handover

Take the concept geometry into the Spectator Technical Centre.
Then close exact product evidence, local structural/access requirements, drawings, freight, installation responsibilities, maintenance and spares.
