Provide equal or better corrosion resistance to the originally designed bent cap and cap to column connection as shown in the project plans.

Limit initial tension stress to 0, “no tension” during release, lifting, and hauling. Precast, prestressed bent caps designed to “no tension” using uncoated strand and reinforcement provides the equal corrosion resistance to uncoated, epoxy coated, and galvanized reinforcement.

If the precast bent cap alternate reduces the number of columns, design the alternate bent cap and columns to meet the requirements for vehicular collision presented in Chapter 2, Section 2, and Chapter 4, Section 7.

Do no use the following without prior approval from TxDOT Bridge Division:

Hollow shells subsequently infilled
Hollow voids
Lightweight concrete
Separate pieces joined together in the field
