Concrete building construction

A building comprising

• a vertical corner post having a pair of first parallel sides and a pair of second parallel sides perpendicular to the first sides, the posts providing a first series of passages interconnecting the first sides and a second series of passages interconnecting the second sides;
• a plurality of generally planar vertical concrete wall panels interconnecting the corner posts and comprising
• a footer having a bottom supported on an underlying ground surface;
• a wall section extending upwardly from the footer having a pair of parallel sides, a web providing a generally planar exterior wall and an interior wall, first and second vertical ribs on the interior wall extending away from the web along the sizes of the wall panel;
• the footer bottom being of a first cross-sectional size in a first plane through the bottom parallel to the ground surface and the wall panel being of a second cross-sectional size in a second plane parallel to the first plane, the second cross-sectional size being substantially smaller than the first size;
• a first one of the wall panels having a first rib abutting one of the first sides of the corner post and providing a third series of linear passages aligned with the first passages of the corner post;
• a first series of elongate tensioned fasteners extending through the aligned first and third passages closing the first wall panel against the corner post and connecting the first panel to the corner post;
• a second one of the wall panels having a second rib abutting one of the second sides of the corner post and providing a fourth series of linear passages aligned with the second passages of the corner post;
• a second series of elongate fasteners extending through the aligned second and fourth passages closing the first wall panel against the corner post and connecting the second panel to the corner post to provide a corner of the building;
• and
• third and fourth ones of the wall panels, respectively coplanar with the first and second wall panels, having a rib connected to the second rib of the first and second wall panels respectively.
