Design principles for decking take care of both a deck’s form and function but highlight safety as well. Keep in mind that deck building codes for properties differ between residential and business so it is a good idea to understand the building codes to ensure everything is in order.
Exits and Emergencies
One of the primary considerations of commercial deck design is providing occupants with a proper means of exit, especially in an emergency. Specifically, a continuous, unobstructed path to the exit must be provided from all parts of a deck as well as the building or structure leading to it.
First and foremost, this means that the installation of commercial decking cannot compromise any pre-existing exits from the establishment itself. When decks and exterior exit stairs are enclosed, they cannot be allowed to hamper occupant ability to reach exterior public areas. Security fences, gates, and areas with excessively uneven or sloping surfaces can all pose a hazard and so must be fixed to reflect proper construction.
To facilitate egress, outdoor walking surfaces need to be slip-resistant and securely attached to the establishment. Walkways and stairways will also need to be designed in such a way that water does not accumulate, which can lead to slippery surfaces.
Lighting
As part of their safety requirements, outdoor walkways and decking need to be sufficiently illuminated so that occupants can see their path clearly, especially in case of an emergency. Just how much lighting commercial decking will require will vary from business to business but, on top of sufficiently illuminating a deck, hooking up deck lighting to an emergency electrical backup system will be a good idea.
Occupancy, Expected Load, and Exits
The size and function of the spaces in the original building and the new deck will dictate the total occupant load for the new combined building and deck. This will, in turn, dictate the number of exits required from the building itself, as well as from the new deck. Each individual space will need to have its exit requirements considered separately; additionally, any area whose only means of exit is through another area will add its occupant load to that of the area it exits through.
Aside from incorporating the right design principles into it, decking will give you the most benefits when made of the right material. Head on over to Part 3 to learn more!
