As a coping material, brick is more water-resistant compared to sheet metal copings and works better to shed water away from the parapet wall.

Sheet metal copings are more water-resistant compared to brick copings, so their use is much more common.

In a typical roof parapet detail, metal cleats are used to secure roof flashing and to provide wind resistance.

The coping over a roof parapet is generally sloped away from the roof.

Stone copings over brick parapet walls are secured via steel dowels.

When through-the-wall or surface-mounted counter flashing options are not available, a reglet on the wall can be a solution to secure the counter flashing.

Counter flashings are typically installed under the base flashings to prevent water infiltration.

GFRC panels are much lighter, so they are more convenient, especially when complex facade design can bring total building loads to critical levels.

Although precast concrete panels are much more effective in creating complex designs, GFRC is preferred due to its low cost.

GFRC panels have higher resistance to impact compared to precast concrete panels.

Compared to precast panels, GFRC panels are more durable and have a higher tensile strength.

Installation of precast concrete panels is less labor intensive and faster however, GFRC panels are preferred due to their lower material cost.

Since sustainability is not a concern of this project, the architect selected GFRC panels rather than precast panels.
