How to make a shed floor

The bearers and joists

Laying out the bearers

The two bearers were placed in position and made parallel (see the plan for dimensions).

Blocks of wood were packed under the bearers where necessary until the bearers were level.

The bearers were not anchored or fastened in any way to the ground, since the shed was intended as a temporary arrangement only.

Placing and fixing the end joists

The two end joists (one each end) were placed and fixed in position. (See the plan for dimensions).

The joists were checked for parallel, the bearers were checked again for parallel, and the joists and bearers were checked for square.

Placing and fixing the intermediate joists

The intermediate joists were positioned. (See the plan for dimensions).

A string line was fixed to the ends of the two end joists.

The intermediate joists were aligned to the string line and then fixed in place.
