| What are the Shed Footing Options? ... |
|
On the next page our Frame Optimiser calculates all the of the bay options
available and their approximate cost. It automatically selects the most cost effective
frame for your shed kit.
|
|
The embedded footing almost always gives the lowest cost frame, but for smaller structures,
the cost difference is usually too small to warrant the extra effort involved in construction.
|
|
Please note that the embedded footing requires a slab! Reo bar goes through the bottom of
the column, attaching to the slab reinforcement steel. (Engineers refer to this as "fixed base" column.)
|
|
For smaller structures we recommend you select "Only show me the above ground footing options".
|
|
For larger structures (12m span and greater) we recommend you consider selecting "Show me the all available footing options".
(Provided you plan to build the structure on a slab).
|
|
Standard above ground footing. (The column is fixed to a footing
bracket that is bolted to the slab).
|
|
Embedded footing - requires slab (or large pad around column).
|

| You decide |
 |
Embedded footings significantly increase the
capacity of the portal frame columns, thus reducing the shed kit
cost.
Embedded footings are not practical if you do not
intend to pour a concrete slab for your shed, or a large concrete pad around each column.

Construction of embedded footings
This involves
pouring an initial footing 350mm below the final
footing level (see Concrete Block in above diagram).
Reinforcing bars are added to the bottom of the column. The
portal frame is fixed to the initial footing. The shed frame is completed
and the remainder of the footing is poured.
