A riser assembly for construction of riser apertures in concrete floors comprises a frame member with a channel forming a shutter. A joist spanning the riser aperture is connected to the channel with a fixing which can slide axially within the channel when connected to the joist. A method of constructing the riser aperture is also disclosed, permitting the adjustment of the position of the joist by sliding the joist axially along the channel after the riser aperture is formed. Upper and lower walls of the channel converge to form a dovetail, which anchors the channel along its length within the settable material forming the floor around the riser, and also helps to retain the fixing within the channel.
