The concrete forming (B) for the walls has vibrators (V) fixed to each forming section in a row of forming made up of multiple sections. The vibrators are electrically operated, and are controlled from a remote central control post. The vibrators can be individually activated, either manually or under a control program, to suit the phase of manufacture of the various sections of the wall. The control of the vibrators can be by the operator controlling the pouring of the concrete into the forming. Normally the vibrator closest to the pouring point is activated first, and those further away activated after various time delays. The vibrators can also be activated for controlled periods.
