#### Fire Rated Feeders
|

## Execution
|

PDI estimating practice is to run all "emergency" feeds

(life-safety or just standby)

||||
in a 2-hour rated assembly.
|
||||
This usually requires no change to takeoff for high-rises
|

since electrical riser rooms are themselves fire-rated.

## Radio Repeater Systems
|
||||
|
||||
### Bi-Directional Amplifier (BDA)
|
||||
|
||||
Used to facilitate radio (usually cellular) communication
|
||||
where it is inhibited by the facility structure.
|
||||
|
||||
Consists of a donor antenna, bi-directional amplifier,
|
||||
and any number of remote units
|
||||
where hard-wired connections to the BDA can be made.
|
||||
|
||||
### Distributed Antenna System (DAS)
|
||||
|
||||
Used to extend wireless communication throughout a facility.
|
||||
|
||||
While active DAS can be said to _require_ a BDA system,
|
||||
in practice a "DAS System" almost always refers
|
||||
to all the equipment required for its operation.

### Structured Cabling:

Refers to a standardized architecture

of telecommunications cabling and equipment.
|

|

Architecture is star-shaped, paralleling building electrical distribution.

* Intermediate Distribution Frames (IDFs)
|

### Community Antenna Television (CATV)
|
||||
|
||||
Used to deliver radio frequency (RF) or digital television programming signals
|
||||
from a single antenna to multiple devices.
|
||||
A building CATV system may include the "picking antenna"
|
||||
or instead include connection to a local utility's.

Whether hotel rooms are dwelling units

and thus whether are hotels are multifamily dwellings per the NEC definition
|

is contingent on the AHJ's interpretation
|

of the requirement for permanent provisions for cooking.

## Strategy
|
||||
|
||||
### Expected Coin
|
||||
|
||||
Estimate expected value and volume for a randomly selected coin.
|
||||
|
||||
| Coin | | Frequency $F$ | Monetary Value $M$ | Radius $r$ | Thickness $h$ | Volume $V$ |
|
||||
| ------- | --- | ------------- | ------------------:| ---------- | ------------- | ---------- |
|
||||
| Quarter | | | 0.25 | | | |
|
||||
| Dime | | | 0.10 | | | |
|
||||
| Nickel | | | 0.05 | | | |
|
||||
| Penny | | | 0.01 | | | |
|
||||
|
||||
$$
|
||||
V = \pi r^2 \times h
|
||||
$$
|
||||
|
||||
### Expected Monetary Density
|
||||
|
||||
$$
|
||||
D = \frac{M_{E}}{V_{E}} \times E
|
||||
$$
|
||||
|
||||
where
|
||||
|
||||
* $M_{E}$ = Monetary value of the Expected Coin
|
||||
* $V_{E}$ = Cylindrical volume of the Expected Coin
|
||||
* $E$ = Packing efficiency
|
||||
|
||||
> [!note] Estimating Packing Efficiency
|
||||
> Estimating $E$ will be tricky.
|
||||
|
||||
### Volume of the "Bowl"
|
||||
|
||||
Let the "bowl" be a hemispherical volume with radius $r_{B}$ enclosing all coins.
|
||||
|
||||
The volume of the bowl $V_{B}$, the liquid volume occupied by the coins, is given by
|
||||
|
||||
$$
|
||||
V_{B} = \frac{2}{3} \pi r_{B}^3
|
||||
$$
|
||||
|
||||
### Total Monetary Value
|
||||
|
||||
The total monetary value of all coins in the bowl is given by
|
||||
|
||||
$$
|
||||
\begin{align*}
|
||||
M_{B} &= V_{B} \times D
|
||||
\end{align*}

### NM/SER Overhead
|

|

Nonmetallic-sheathed cables are combustible,
|

so not permissible in Non-Combustible (Type I, II) constructions.

See [[ibc-construction-types]] for more info.

#### Concealment
|

|

Cable type wiring methods (MC, NM, SE)
|

may only be used where they will be concealed from view.
|

|
||||
### PVC in Slab
|
||||
|

May require rigid stub-ups in certain cases,

which could make EMT more cost-effective.

Consult with the Senior Construction Estimator in this case.

#### Fire Rated Feeders
|
||||
|
||||
PDI estimating practice is to run all "emergency" feeds
|
||||
(life-safety or just standby)
|
||||
in a 2-hour rated assembly.
|
||||
This usually requires no change to takeoff for high-rises
|
||||
since electrical riser rooms are themselves fire-rated.
