When construction bids for St. Peter's Lutheran Church building in Columbus, Indiana, exceeded the 3.5-million-dollar original estimate by 70 percent, plans clearly had to be reworked. Eight months later modifications were completed and the cost had been reduced without compromising the original design. The church building floor slabs, footings, and walls are structural concrete, supporting a steel-framed roof. The curved concrete walls to the north are clad in brick, with a concrete base and copper fascia. To the south, the flat structural concrete fin walls remain exposed with horizontally banded brickwork inserts and a pattern of vertical and horizontal rusticated joints and exposed tie holes.
Exterior wall pours began in the fall and above-grade work proceeded during the winter. Forms were built up as flying gangs. For work at upper elevations, suspended scaffolds were attached to the forms. Use of insulated forms together with ready mix temperatures specified at a minimum for 65 degrees made it possible to continue concrete placement without heated enclosures or added protection. The concrete mix 28-day strength specified was 4500 psi, however most of the concrete tested at more than 5500 to 5700 psi at 28 days.
