storefront door

[Nicole Brooks]

Do any of you all ever detail the storefront door/storefront sitting on sidewalk and not the interior slab? The contractor wants to run the sidewalk under the threshold and it on that and not the interior slab. Location: Jacksonville Florida, 30,000 sf single story concrete tilt building.

Isn’t the sidewalk city property?

no, it's a private industrial park.

Having the storefront framing installed on to the sidewalk may improve the
Accessibility of entering that particular space........It would improve the
Accessibility for persons with impairments, along with the correct slope
once inside the space.

Outside, hopefully the sidewalk would be sloped away from the building,
in an ADA compliant manner, that would also prevent flooding \
excessive rain events from entering the spaces.

If the sidewalk enters the building it's not the sidewalk anymore....

yes, my exterior concrete walks are typically haunched into my foundation wall with the seam between walk and interior concrete slab hidden under the door threshold. The walk also gets structurally tied into the foundation wall with rebar to prevent it from lifting. In cold climates if the walk isn't tied into the foundation there is a risk of front heaving causing the walkway to rise and prevent the door from opening easily.

If this is how they had proposed to do it, then I wouldn't have a problem, but the sidewalk is just floating and I worry that which such significant swings in temperature that we are seeing, the sidewalk slab could heave and the subgrades could get washed out and break or pop out the storefront.

Or get jammed closed.

this, or the creation of a tripping hazard would be my biggest concerns

Which is why we have this now:

1809.5.1 Frost Protection at Required Exits​

Frost protection shall be provided at exterior landings for all required exits with outward-swinging doors. Frost protection shall only be required to the extent necessary to ensure the unobstructed opening of the required exit doors.

South Floridian here; I don't understand what frost or heaving are , but I would check with structural. Maybe not an issue up there since wind loads are lower, but down here they are too great to attach storefront to a sidewalk (assuming your sidewalk is an unreinforced 4" slab).

What do the approved construction documents show? Call me old-fashioned, but I thought a building permit allowed contractors to build what's shown on the plans ...
