3.1.5 Mounting holes : The Manufacturer must provide the location, size,
and angular displacement of required mounting holes.
3.1.6 Contact points : Information must be provided in regard to han-
dling, storage, and installation.

3.2 Order Specifi c Information

The Manufacturer may also provide the following information, on a
specifi c order basis, when required by the Purchaser:

3.2.1 Groundline reactions : These include required moment, shear, and
axial forces.
3.2.2 Defl ection information : This should be available for specifi c load
cases.
3.2.3 Variances : Any unusual variances encountered during the design
process (e.g., guy tensions exceeding the allowable for the sizes and
quantity specifi ed, etc.) should be available to the Purchaser.

factor stress to the statically cast 28-day f c value, deter-

mined by tests

The numerical square root of f c , in units of “psi”

used in evaluating the permissible level of cracking
stress in concrete. The maximum value of f
