Make all modifications listed below. No re-design or analysis of beams or girders is needed.

Prestressed Concrete I-girder or X-beam Standard Bridge

1. Span Standard:
   • Change slab and slab overhang thickness dimension to 8 ½".
   • Change slab top clear cover to 2 ½".
   • Increase DL deflections 6 percent.
   • Add ½" to top of deck to top of girder dimension (or X dimension) and Y dimension.
   • Increase slab concrete CY volume by an amount equal to (0.00154 * Deck SF).
2. Abutment Standard:
   • Add 0.2 CY to abutment concrete volume.
3. PCP Standard:
   • Reduce the maximum allowed slab thickness increase in note 9 from 2" to 1 ½".
4. IGCS or XBCS Standard:
   • Change slab thickness in note 2 and Section A-A to 8 ½".

Steel Beam Standard Bridge

1. Span Standard:
   • Change slab and slab overhang thickness dimension to 8 ½".
   • Change slab top clear cover to 2 ½".
   • Add ½" to top of slab to top of beam dimension.
   • Increase slab concrete CY volume by an amount equal to (0.00154 * Deck SF)
2. Abutment Standard:
   • Add 0.2 CY to abutment concrete volume.
3. SBSD Standard:
   • Add ½" to Y dimension.
   • Increase DL deflections 6 percent.
4. SBCS Standard:
   • Change slab thickness in note 3 and Section A-A to 8 ½".
5. SBMD Standard:
   • Change clearance from top of deck to stud connector to 2 ½" in Stud Connector Detail.
6. PCP Standard:
   • Reduce the maximum allowed slab thickness increase in note 9 for steel beams from 1" to ½".
