• a series of tie members extending between the form members, the tie members comprising a pair of end parts, with a middle part between the end parts, the end parts and the middle part joined together in serial succession;
• each tie member having opposed ends with a web member between the ends extending along a web axis, a bearing member at each end of the tie member, extending generally transverse to the web axis and embedded in a respective form member and each end of the tie member having a stabilizing member extending generally transverse to the web axis, spaced from the bearing member and embedded in the a respective form member adjacent the interior form surface thereof;
• and
• the tie members at the ends of the series have smaller bearing plates than the remaining tie members.
