OVERHANG FACING EAST:

The overhang (facing east) that was removed by AG contractor was approx. 3 feet in length.

The existing rebar appears to be located in the center of the slab instead of at the top of the slab where they would have been more effective in transferring the loads.

Trying to rebuild the overhang will require additional demolition so that the bars can be spliced.

Since the bars were not placed at the correct position to begin with, it may be that a larger area of concrete of the roof slab would need to be removed in order to recreate the structural support.

Shoring will be required in the interior space of the pool lounge to provide temporary support of the roof slab during the work,

In general cantilevered sections of the slab are a liability since there is no redundancies in the structural system.

In an outdoor application the maintenance becomes critical especially if the slab is prone to water infiltration.

Based on the above TT recommends to do NOT rebuild the demolished portion of the overhang facing west.

The exposed and rusted rebars at this area should be cut off and the area of exposed concrete should be patched and closed off.

TT will await direction from the board of director on whether the overhang should be rebuilt or not.

OVERHANG FACING SOUTH:

Based on the above Thornton Tomasetti does not recommend to rebuild the overhang facing east in kind.

The simplest and most inexpensive solution is to cut the expose rebars and close off the area of the slab that has been exposed by the demolition.

The overhang facing south is made of precast reinforced concrete outriggers running at approx.

48” on center. The outriggers on both east and west side exhibit concrete spalling and rusted rebars.

The contractor has already removed the loose concrete and exposed the rebars.

TT will instruct the contractor to scrape and paint the rusted rebars and patch the area of repair.

The overhang facing south appears to be structurally sound.

ROOFING AT POOL LOUNGE:

The roofing system is compromised. IT appears that a re-roofing job on top of the existing roofing membrane was performed in the recent past. This type of work is usually a quick way to restore water tightness, however it is NOT the recommended type of repair.

If there is water trapped under the old roofing system, placing a new layer of roofing on top of the existing roofing system will only worsen the situation. The water eventually will get absorbed by the concrete and will caused the reinforcing steel to delaminate and rust.

TT recommends to remove the existing roofing system, inspect the slab surface for potential damages such as spalls and cracks, repairs these conditions, and then install a new roofing system.
