As addressed in the lecture, the FOA's proposal for the New World Trade Center is interesting example in that it used the egress system as a key design concept. The simple and rational design approach for the exit-circulation system led to the unique high-rise building form: the four separate volumes wavy in vertical direction are designed to touch and connect to the neighboring one at different levels, while they go down from the top to the bottom. This design strategy enables occupants to transfer to the other stairways and have alternative exit paths in case one becomes unavailable.

We often underestimate the extent to which regulation defines the form, material and space of architecture and impact our environment. How successfully and smart we deal with those inevitable constraints determines our performance in practice.

Diagram 1. Mixed Occupancy

This diagram describes the fire rating requirement for the mixed occupancy(a building has more than two different occupancy types.) If you want to put an assembly space in the occupancy type-R building(with no sprinkler system), you need to separate the two spaces with a 2 hour fire-rated wall or enclosure.

Diagram 2. Accessory Occupancies

Diagram 3. Fire-Resistance Rating Requirements for Exterior Walls Based on Fire Separation Distance

This diagram illustrates the direct relation between fire-resistance rating requirements for exterior walls and fire separation distance. If your occupancy type is R1 with construction type IA and the fire separation distance (from the exterior wall to a lot line or imaginary line) is between 10 to 30 feet, then the exterior wall is required to have at least 1-hour rating.

Kelly Island - Quarry Site

There was a great hollow within the nature. It was created a hundred years ago for quarrying limestone, which was once the main industry of the island, but now left abandoned. It feels like a plateau, as John was saying, with sparse plants and weeds coming out of the rocky ground, even though the cause of the bizarre landscape is different from that of the nature. With the lapse of time, underground water has sprung out and covered a portion of the site and started to bring new ecology into the land.

The original size of this photo is much bigger(about 11000px X 1800px) than that I have posted above, so just let me know if anyone needs this.
