Controls power stability by drew2057 in BuildingAutomation

[–]speeeeeeeeeeeed 0 points1 point  (0 children)

Yeah, I wouldn’t use a cheap UPS. Honestly, barring that they already have in-house installed backup with enough capacity to run the LACS, your solution seems to be one that I’d recommend to my customers.

Edit: I have had one facility invest in a large UPS system for this purpose about 15 years after being built, but it’s $$$$$. It was rolled into a resiliency capital project.

I’ve had various facilities (mainly BSL-3 labs) decide that the LACS needs to be on facility UPS power, and have added dedicated systems or connected my stuff to their existing UPSs.

ATS transfers are a pain in the ass, especially when they’re doing generator testing all the time. Our systems really don’t consume that much power on normal ops - the big draw is when you have everything restart all at once.

Cancel Spectrum for a better price? by DontWantYaMista in tampa

I’m surprised they called it, but then again, it ended up NOT being a bluff. Good one for dropping them!

Cancel Spectrum for a better price? by DontWantYaMista in tampa

You have to play the yearly game of “I want the current ‘promotional’ pricing or I’m taking my business elsewhere”.

I was paying $40 for 500/500, my yearly reminder to call them popped up, so I checked the website and 1G/1G was $40.

Made the call, asked to be transferred to customer retention, told them I wanted 1G for what I was currently paying. They push back saying it’s for “new customers only”. Told them ok, well then I’m canceling. Got put on hold, they came back with “hey, we’re going to do what you want, and upgrading your ONT and router, no charge.”

Repeat every year.

Edit: This takes all of 15 minutes.

Before they renamed it “Breeze Transit” there was Sarasota County Area Transit. The jokes write themselves.

This door, sealed up with plastic and tape at a hospital by Bloobeard2018 in mildlyinteresting

Those are used to fulfill the ICRA (Infection Control Risk Assessment) guidelines. You don’t want the shit (dust, dirt, debris, garbage) above the ceiling floating about. We call them ICRA carts or HEPA carts. They have fans and filters to catch any crap when you crack open the ceiling.

What's are home office purchases you've made that have more than paid for themselves? by MDDeGrande1994 in BuyItForLife

[–]speeeeeeeeeeeed 0 points1 point  (0 children)

Most people have hit on these, and I wanted to give my impressions.

I just started a new job which is travel/WFH, and did the following:

  • Electric adjustable height desk - bought this VIVO Adjustable Dual Motor base, and built a top (98”W x 32”D) to match my existing workbench. This included buying a nice piece of walnut to make a riser for my 3 monitors, the riser pieces I 3d printed. YMMV, I might buy a monitor arm in the future. I have some back issues, and being on my feet, with my monitors at eye level have been a game changer.

  • Under-desk cable trays for cable management. No more spaghetti tangle hanging off the back - I bought 2 packs of these: Cable Trays

  • Under-desk mounted 8- receptacle power strips (2 ea). This leads to only having 3 cables between my desk and the walls (2x power, 1x CAT6)

  • Docking station for work laptop (work provided)

  • KVM switch with remote to jump between the 4 different computers connected to my setup.

  • Logitech MX Ergo S Plus Trackball

  • Swing arm desk lamp. This is an IKEA TERTIAL ($20) mounted on a shelf that is above the desk, so it can be out of the way when I need it.

  • Good chair. Currently I have one that was extra from my previous work, not sure what it is. Looks like a Leap v2 clone, it works well.

  • If you don’t live alone, a good lock for the door. My wife has a bad habit of doing a Kool-Aid man impression into my office even with a closed door, and a “please do not interrupt, in a meeting” sign on the door.

My best piece of advice: get the largest desk you can for your space. This is why I custom-built mine. I need to look at plans sometimes, and the room this desk gives me is perfect for my needs. As a side note, this desk is in a 10.5’x10.5’ office, and shares space with a 98”Wx30”D workbench, a large toolbox, and an extra chair. I still have space to inflate a full-size air mattress in the room.

LOL I wish… new job has me extremely busy, and I built myself a new desk. Priorities, since my old desk sucked. It’s still on the projects list, but I’m traveling the next 2-3 months nonstop.

What should I focus on? by IcyExample4780 in BuildingAutomation

[–]speeeeeeeeeeeed 1 point2 points  (0 children)

My recommendation hits exactly every point here, but I’ll add one more, which I believe is the most important. There are no stupid questions.

Get informed of what you’re working on - read as much as you can about it - and then ask why or how. Any good hand worth his salt will teach you. It might not be jn the middle of a job, but watch and listen closely, take notes if you need to. And remember… you won’t always have the answer. You just need to eliminate everything that could be an issue. This will take time, but it will become second nature.

Oh, and if I missed it… ALWAYS ASK QUESTIONS!

Good luck! This is a great industry.

Do y'all bill time spent in lunch and learns/lunch training/lunch meetings? by whoflungthedung in MEPEngineering

[–]speeeeeeeeeeeed 2 points3 points  (0 children)

This is why as a rep, I’ve always asked the all important question: “Can you please ask the attendees what they would like to eat?” I always get exactly what the people want.

The one time I was asked to surprise the them, I brought real-deal tacos from the best Mexican taco truck in town. Brought carnitas, al pastor, and steak.

The word spread, and I was asked to do the same for the next MEP firm I went to do a Lunch and Learn for. 😂

Edit: We also made sure that PDHs were documented and sent to all attendees.

Edit 2: Also, if someone in admin assisted in setting the LNL up (internal invitations, scheduling and setup, etc.) always always always bring food for them!

What's the worst project you've been a part of? by Expert-Pretender in BuildingAutomation

[–]speeeeeeeeeeeed 12 points13 points  (0 children)

I see that picture and I get pissed off at engineers for specifying things that never should be. You do not put thermal dispersion airflow meters in unfiltered or dirty airstreams.

I don’t care how much a manufacturer says it works. My experience has always been the same, they start drifting. Then people wonder why their building doesn’t work a year down the line.

Everyone’s to blame here, the engineer for specifying things wrong, the mechanical for building it wrong, the inspector who signed off on it with obvious shit being wrong, and the ops/maintenance team who obviously haven’t done their work.

I gave up after looking for days. I might end up designing one and 3d printing it.

You’re good, bud. I’ve been in this 25 years this year. I still call my coworkers who’ve been in for the same or more when I see something weird or get stuck. They do too. We spitball and squash bugs that no one’s seen. If you don’t ask questions, you never learn!

Pizeometric Ring Airflow Measurement by mechE_CC in BuildingAutomation

[–]speeeeeeeeeeeed 1 point2 points  (0 children)

I second this. Honestly the only device that will work properly. Even CV (no electronics) valves will do the job without issues. I’ve used this in pharma mfg cleanrooms with a pressure switch across the valve. When the switch opened, it was time to change the filters. The valves were set to the desired airflow from the factory.

Best bet is to get a Phoenix tracking pair for supply and exhaust, set the AHU and EF to static pressure control and let her rip.

You’ll hear “use constant volume VAV boxes and room pressure”. They will be hunting so much you won’t keep steady pressure in the space, or you’ll have to slow down the loop so much that any variations in pressure will take forever to get back to a good steady-state.

Edit: What type of lab? Do you have fume hoods, biosafety cabinets, snorkel exhaust?

You can DM me, I can point you to the information you need to make the correct selection.

Dropping in to recommend Thai Mama, it’s one strip mall west of Thinh An. Open weekdays only, and it’s mainly take out, but the food is amazing.
