July 7, 2011 - Isolation Pockets and Full Penetration Welding

With the majority of the two steel packages in place and the second floor slab poured, workers are now tending to smaller miscellaneous items.

Now that the second floor slab is placed and the steel columns are true,
the isolation pockets at the base of the East wall columns are being filled with concrete,

Looking south down central corridor in the clinic, sterilization is to the right.
These isolation pockets at the base of the short columns are round and still need to be filled with concrete.

Welder works on full penetration welds as Special Inspector stands by.
Each one of these special Full Penetration Welds takes about half a day.
There are at least 40 of these welds required on the project.

Welder works off special platform in a hard to reach spot.

July 5, 2011 - Second Floor Slab

Last Tuesday, June 28th, 2011, the second floor slab was poured.  This is a significant milestone in the project.  Now that the second floor slab is in place, the pace of construction should pick up. 

Concrete placement started at daybreak.

The concrete specifications call for a 5,000 psi mix.    It took several truckloads to complete the pour.

This is a floor drain in the utility room.
That tube connected to the drain is part of the trap primer.
Here is a typical trap primer schematic.
