Introduction

This zone is currently an amalgamation of existing parts of the space that now have a single point of contact. A result of this is that there is no picture of the zone that would not also include all the other zones as the power conduits themselves are managed by this zone even as they worm their way into every crack and crevice. Another aspect of this zone is that there is very little that needs to be centrally located here on the wiki, most of the items have their own page or subcategory and these will be cleaned up but generally left to themselves and links to them consolidated here.

One of the responsibilities of the Infrastructure Zone is maintaining the Security Cameras and approved reviewers thereof.

Legal limits

The question frequently comes up why we don't do certain things. The answer given is usually 'it's not allowed', 'fire marshall said', or 'against our certificate of occupancy'. All of these are bad answers. The real answers comes from code that is not cited in the terse answers that are used to shut down people trying to do cool things. This is where we can keep track of reasons why we can't do things with sources cited so we can know when we meet the requirements to do the cool things.


Fire code stuff

Fendale uses international fire code 2012 edition

https://library.municode.com/mi/ferndale/codes/code_of_ordinances?nodeId=PTIICOOR_CH9FIPRPR_ARTIIFIPRCO

The fire marshal can modify fire code "when there are practical difficulties in the way of carrying out the strict letter of the code; provided that the spirit of the code shall be observed, public safety secured, and substantial justice done."

The international fire code references the international building code, I assume that applies. I reference the same year.


Item Description Source Code
Wood shop If the woodshop area is 2500 square feet or larger it needs a sprinkler system. Sprinkler systems are expensive, you have to pull a permit to connect directly to the city water line and the permit alone is at least $15,000 depending on where you're connecting to and what other lines are around that you have to avoid. Quote is from Fire Marshall visit (July 9 2018)
Note that the code only says this matters if we're fire group F-1, which would mean a bunch of other issue for us in terms of sprinklers and stuff unless we build that wall.
2012 International Fire Code Section 903.2.4.1 https://codes.iccsafe.org/public/document/IFC2012/chapter-9-fire-protection-systems
Fire extinguishers 75 feet of travel distance
30 feet of anything flammable. Code says it can be higher in some cases, but someone else will need to go understand the code
- Flammables storage containers
- Welding
- Jewelry

Placement: Easily accessible and marked well etc.

Hangers: at least 4 inches off the floor, less than 5 feet. If over 40 pounds, less than 3.5 feet.


Copies of a downloadable fire extinguisher map have been posted at various locations throughout the space.

2012 International Fire Code Section 906 https://codes.iccsafe.org/public/document/IFC2012/chapter-9-fire-protection-systems
Ceiling level storage no storage within 24 inches of the ceiling (not the metal joist, but the corrugated metal) Fire Marshall visit (July 9 2018) Unknown
We cannot have open flames or do auto work Our COO says we can't do auto work.
We would like to be fire group F1-1
https://codes.iccsafe.org/public/document/IBC2012/chapter-3-use-and-occupancy-classification

According to the international fire code, fire group F1-1 needs:
https://codes.iccsafe.org/public/document/IFC2012/chapter-9-fire-protection-systems

automatic sprinklers if
- fire area exceeds 12,000 sq ft; 1115m^2
- woodworking in fire area over 2500 sq ft 232 m^2
- Combined fire areas in entire building, including mezzanines exceeds 24,000 sq ft 2230 m^2

smoke/heat removal
- fire area more than 50,000 sq ft 4645 m^2


definitions:
- fire wall: external wall
- fire barrier: internal wall

We need a fire barrier

Fire barrier definition: international building code 707
https://codes.iccsafe.org/public/document/IBC2012/chapter-7-fire-and-smoke-protection-features
Fire group f1-1 needs a 3 hour barrier, made of "materials permitted by the building type of construction"

Openings can be less than 25% of the width of the wall

Doors and stuff have code requirements
interior exit passageway IBC 1023.3, not sure this is what we need
- TODO: lookup the door in a fire barrier rules

air ducts: IBC section 717.5.2
- We need "approved" fire dampers in the ducts unless
- Penetrations are tested in accordance with ASTM E 119 or UL 263 as part of the fire-resistance-rated assembly.
- Ducts are used as part of an approved smoke control system in accordance with Section 909 and where the use of a fire damper would interfere with the operation of a smoke control system.

Eric Merrill talked to a previous fire marshal in 2011, who said that he would count the current wall as a fire barrier, but we would need to fire rate the windows up top and the doorways. The easiest way to do the top would be to build wood frames and put 2 layers of drywall over it.

TODO List

^^click the title to edit the todo^^

The following list is an attempt to offer up suggestions of tasks that could be accomplished throughout the space by people interested in helping out.

Feel free to take charge of one or more of these items as your time and expertise allow. If you have taken charge of a task, please put your name into the field next to the task.

Should you run out of time or ability to complete a task, make sure to post on the mailing list and "fail loudly". This ensures that task status is shared, and no task languishes in silent failure.

Task Name Description Priority Champion
Add plug and socket for TIG welder The TIG welder is wired in to the disconnect directly which makes it inconvenient to move around. Ideally, this will utilize a relay with auxiliary, allowing the TIG and chiller to operate from a single switch. 5
Building ground Tie all the breaker panels to the building beams for ground. Make sure the bus-bar is as well. 4
Conduit Labeling Designate all conduits with the circuits contained therein, and "downstream" (toward-end-device) "flow" arrows. 2
Sewer lines scope our lines, maybe snake them all the way to the street (rent one at pot lock) 2
shower to mop sink convert our shower to a mop sink, it can still be used as a shower in emergencies but it has a strainer so you can dump mop buckets in to it and a hose to fill with. 2
Repair big sink needs new seals, something to stop the hot water leak(someone replaced the seals inside the faucet at a potlock, and it didn't help), and new bits for the sprayer. 1
Roof vent Wood shop vent needs one of the motors on the motor shelf near the bike zone to be installed. 2
Front door replacement Find a replacement door, probably frame, and install it 1
power for injection molding chiller replace fuses with 40A ones, the cable running it is awg 8 1
Power Runs We need more circuit breakers, exactly where is to be determined, but here's a preliminary list
  • Label dust-collector disconnect on north wall
  • Label all outlets with the panel and breaker that serves them
1
Floor pour in cart storage needs real concrete north of the treehouse stairs. 2
floor smoothing in wood shop needs real concrete 1
floor smoothing by laser/vinyl needs leveling compound, acid, whole nine yards 1
hot water heater look at securing north side to the wall 2
Thermal Insulation The space leaks some energy in winter, let's find some major leaks and get some solutions in place. Luckily some of our members have FLIRs. 1
Storage rules Storage rules don't quite match the parking permit thing. Fix the rules and put it on the storage page. 1
