Indoor Maps - Egress Check, Evacuation Plans, Areas and Camera Coverage

The Analyze tab of the Indoor Maps kit answers questions about the building itself, using the rooms, doors and walls of your venue.

These checks are estimates for planning from the drawn floor plan. They are not a code review or a certified measurement. Confirm them with your fire marshal, architect or measurement professional.

Before you start

On the Shapes tab, click Choose Shape, pick a shape and fill in Walls, Doors and Rooms:

• Rooms: what the room is used for (for example Offices or Assembly), and a fixed number of people if it has fixed seats.
• Doors: the clear width and whether it is an exit. Doors in outside walls count as exits unless you say otherwise.
• Walls: the material.
• Safety equipment: choose a marker and set it as a Fire extinguisher, Fire alarm, AED, First aid or Assembly point.

On the Analyze tab, set the Building: sprinklered or not, whether it has an emergency voice/alarm system, the main occupancy group, the default wall and floor materials, and the units. Automatic units show feet for buildings in the US and metres everywhere else.

Egress check

Click Check Egress. The kit walks from every spot in every room to the exits, around walls and through doors. On upper floors the stairs are the exits. It checks these sections of the 2021 International Building Code, the building code used in the United States. Codes from other countries are not checked yet.

1. Travel distance to an exit (1017.2)
2. Common path of travel (1006.2.1)
3. Dead-end corridors (1020.5)
4. Exits far enough apart (1007.1.1)
5. Enough exits for the number of people on the floor (1006.3.3)
6. Rooms with too many people for one door (Table 1006.2.1)
7. Exit width for the number of people, and what is left if one exit is blocked (1005.3, 1005.5)
8. Exit door clear width (1010.1.1)

Click a finding to see it on the map. Under Show on the map, pick Travel distance to an exit or Common path of travel to colour every spot by how close it is to the limit.

Evacuation plans

Pick a room and click Open Plan, or click Plan For A Shape to start from a door or a marker. You get a printable page with "You are here" at the room's door, the route to the nearest exit and a second route to a different exit, the fire equipment on the floor, a legend and short instructions. Click Download SVG to save it.

Areas and occupancy

Click Measure Areas. For every room you get its net area, its class (tenant, floor common, building common, vertical penetration or excluded) and its design occupant load from IBC Table 1004.5. For each floor and the whole building you get the gross area, rentable area and load factor by the BOMA load-factor method. Click Download CSV for a spreadsheet.

Cameras and line of sight

Put a marker where the camera is, give it a facing (0 is north), a field of view and a range, then click Choose Camera Marker and pick the marker. Click Check Coverage to see what your cameras see and where the blind spots are. Walls and closed doors block the view; glass does not.

Click Check Sight From A Point, then click the map, to see everything visible from that spot.

Cameras are shown only to people who can edit the map. Visitors to a shared or embedded map do not see them.

The heatmap goes away when you leave the Analyze tab. Your check results stay: come back and pick a layer under Show on the map to see it again.
