A concrete footing is laid by a set of forms each with side walls forming an elongate area and transverse connecting elements with at least one lift element mounted for lifting by a fork lift system extending across the side walls. The forms include legs engaged into the ground and adjusted to a required height relative to the ground. After setting of the concrete the elongate frame members are lifted from the concrete using the fork lift system. Connecting members shaped to match the side walls are clamped on an inside surface so as to bridge between the frame members. The set is carried on a transport cradle which includes a pair of side walls on which a lowermost one of the set sits with a pair of transverse sleeves connected across the side walls by which the cradle is lifted by the forks of the fork lift system.
