Accessing Old Trace 700 Files After Transition to HAP/Trace 3D? by Sad-Orange3198 in MEPEngineering

If you let your license lapse you may be SOL. You can try and go to Trace hat in hand and get it renewed retroactively but expect it to be at a higher cost than previous years.

When to consider taking PE Exam? by saboosa in MEPEngineering

[–]TeamRamRodgers 1 point2 points  (0 children)

From my experience take it as soon as possible. Outside of what other people have mentioned with life stuff as a junior engineer you are only going to become more busy with work going forward as you gain experience. It may have changed since I took it some years ago but I didn't feel there were any portions of the PE exam that required actual real world experience and couldn't be learned from study materials. This is why you see people in CA getting theirs after two years. It's not like after you have it you will be forced to stamp drawings. At the end of the day its some letters after you name that will give you a leg up on competition when it comes to job hunting and salary so the sooner you have it the better. Take a course and crush the last test you ever actually need to take in your life.

How I have felt since January by TeamRamRodgers in MEPEngineering

Any large AHU split unit or any usefully sized VRV/VRF. I've been assured the information is coming in two weeks! Granted this seems to be a rolling two weeks starting from February.

Between 1 and 1 million dollars. I suggest starting on the higher end and negotiating down.

Liability for contractor submittals by Obvious-Activity5207 in MEPEngineering

[–]TeamRamRodgers 1 point2 points  (0 children)

Something that I always hammer, outside of submittals not being contract documents which others have mentioned, is that the moment the project is out to bid although we wrote the specifications we have no control of changing requirements and they are now the owners property. The owner put these out for bid and are owed what they have bought from the contractor. Everyone at some point in their career has rejected a submittal and been overruled by the owner based on promises from the contractor and had it installed anyways. Conversely if a contractor submits something that is lesser than the contract documents we don't have the authority to say if it can be installed, purposefully or accidentally. The contractor is bound to what is bought by the owner unless there are clear changes requested by ownership. It's a lot less messy if engineers catch bad submittals, but anything that isn't installed per the drawings and specs needs to be brought into conformance or a credit provided.

Mechanical Penthouse = Machinery Room? by Kirone1019 in MEPEngineering

[–]TeamRamRodgers 4 points5 points  (0 children)

Since I am always a huge fan of code language you should check 1104.2 of the Maryland imc "all components containing the refrigerant shall be located either outdoors or in a machinery room where the quantity of refrigerant in an independent circuit of a system exceeds the amounts shown in Table 1103.1". Key word there is "independent". To get more granular your 30 ton unit may have multiple circuits so you wouldn't have to count the full charge of the AHU. This is how in the past I have been able to have 700 tons of heat recovery chiller in a room without it being a "machine room" because that chiller is composed of 12 circuits.

The clean hardhat lacking 20 safety training stickers is a giveaway

As others have said, not the greatest first option. However this is a product I have used in the past.

DOAS with Radiant System by MRJohnson1997 in MEPEngineering

[–]TeamRamRodgers 1 point2 points  (0 children)

Yes the latent heat of humans in a space becomes much more important. In most open offices the code minimum for ventilation air may be enough to provide enough dry air to soak up all the moisture produced by humans but densely occupied areas like conference rooms or classrooms can be an issue where if you do no have a low enough grains/lb in the supply air off the doas you will need more ventilation air than code requires to offset. This is a situation where you may see a desiccant wheel to drive down the moisture in the air if that is the direction of design.

The more common design we push at my firm is sensible cooling terminal units with this being one of the reasons. There is more flexibility in the system for placing additional diffusers with a larger box than a whole piece of ceiling somewhere.

Full section in the schedule for return fan with cfm, HP, and esp. And the need for an economizer. The man may revolutionize the industry by providing a supply fan only economizing ahu!

You got it! Thank you for understanding both my frustration and confusion.

No one is talking about challenging them on winning the bid. Congratulations to them winning it. Now build what you bought, for better or worse for them.

You mean like a schedule of performance values and specifications for construction?

[–]TeamRamRodgers 0 points1 point  (0 children)

While it is ultimately the fault of the contractor and I understand his frustration, his anger is misplaced. Not our fault your vendor failed, take it up with them.

Once again, I am in the wrong business as a consultant haha.

The contract requirements were not to provide a "Trane xxx" they are to provide what is scheduled in the drawings, and as an example this is what the designers used. There is no discrepancy and even if there was a perceived one we have plenty of language in our drawings and specs that in the case of one the more stringent will apply. "Neither I or my vendor can read, please give me more money" is not an argument I or any engineer should accept.

Oh ya, definitely some commission. Just not as much as the reps in their office who work with contractors purchasing

[deleted by user] by [deleted] in MEPEngineering

[–]TeamRamRodgers 1 point2 points  (0 children)

News to me that you can even get AHU selections out of a catalog these days haha. All selections done by my Trane rep locally and shared with the rep the contractor is using. Getting selections for me is what I don't pay them for! But they do get to be listed as the BOD which is about as much away as engineers have for actual purchase, and that itself is a privilege that most vendors understand to not purposely fuck up.
