5 X X Levels 1, 1A, 2, 2A, 3, 3A Strengthen DT floors where heavy traffic is occurring specifically at the lower levels at turn around area at the end of the ramp

High

6 X X Various Locations

Replace all joint sealants at each DT joints, repairing any deficient flange to flange connectors that were encountered during the replacement process. It is recommended that the first two top levels (Level 4A and Level 4) should be prioritized first as well as any DT joints at any level in the garage that require immediate repairs.

High

7 X X Various Locations Repair all spalled/scaling delaminated concrete, exposed rebars, in all areas specified in the report and in other areas found in the garage.

8 X X Various Locations Provide/replace the required connections at Shear Wall with DT floor slabs diaphragms where found to be missing, corroded, or inadequate

High

9 X X Various Locations Remove and replace joint sealants around all shear walls, columns, spandrel beams, and walls. This includes perimeter shear walls, columns, spandrel beams, cmu walls, and precast walls. It is recommended that the first two top levels (Level 4A and Level 4) should be prioritized first then work towards the lower level.

High

10 X X Various Locations Repair concrete toppings for proper elevation and re-routing of stormwater runoff towards the intended drain. High

11 X X Level 4 Increase joint inlet opening by cutting the DT flange at the beginning of the ramp from level 4 to 4A to allow for better drainage flow to the trench drain below.

High

12 X Level 4 Repair large column spalled at the southeast corner of stair tower at Level 4 at the landing. High
