N E T GENERAL & TECH INFO CHARTS Typical Form Tie Spacing For Wall Forms Note: The above table is based on the following conditions. Concrete - Made with type 1 cement weighing 150 pcf. contains no admixtures, slump of 4" or less and normal internal vibration to a depth of 4 ft. or less. Concrete Temperature - For practical purposes, 50 °F is used by many form designers as the temperature of fresh concrete during winter, with 70°F being used as the summer temperature. This "rule of thumb" appears to work satisfactory unless the concrete has been heated or cooled to a controlled temperature. Form Ties - Safe working loads are based on a factor of safety of approximately 2 to 1 (ultimate to SWL).
