The thickness of the bond beam is consistent with the column at 15cm. The wall thickness is 9cm. Therefore the 6cm caibro (wood member) will suffice in padding out for the void that is created. It is screwed to the bottom of the formwork on the interior side of the wall. 4/2 rebar is drilled through the formwork and bent over on each side to prevent a lateral blowout. Additional cross members are screwed to the top and wire is wrapped completely around the formwork. All formwork is flushed to the top and leveled from the top to ensure that the trusses and roof system plane out properly. Shown above is the bond beam and metal retention members being bent with a pipe found on site.
