No electrical prints for 30x170 office/tire storage addittion...

[ctaylo360860]

I'm currently working on an addition for a building. the building is a tire shop/parts supply/gas station. There are absolutely no electrical prints, and I'm guessing that the building prints will be a vague drawing of what the finished product is to look like. The jobs that I have done before moving to the country always had a set of sealed prints that were turned into the state for inspection purposes.... The addition I'm told is around 30x170, around 30x20 is going to be additional office space, the remaining 20x 150 will be used for tire storage... I'm wondering what I'm going to need and where I need to start to make sure I meet requirements for article 220... I'm going to be meeting with an architecture firm tomorrow, and should have a better idea of what will actually be going into the addition. As I understand it will be lighting and receptacles for the office area, and for the tire storage... the only new equipment that has been talked about is possibly a larger furnace and air condition.... Am I overthinking this, or am I basically going to be doing the engineering for the electrical? Any and all help is always appreciated!

I think you answered your own question.
Just make sure you don't do their engineering work for free.

That’s one of the issue because I’m an in house electrician....I won’t be able to charge them anymore or less. I can only bring this to the table when I ask for more money as I’m doing much more than just the electrical contractor job....

to start I’m trying to get a demand load from poco of the existing service and building. from there I’ll need to get actual dimension of outside perimeter and specs of what’s going in on the addition so I can figure general lighting and receptacle load calculations to see if they need to upgrade existing service?
I have a master license, but have only had it for a couple years and am still learning. this seems over my head as I’m going to have to try to do engineering and the work and stay ahead of the other trades.... please any and all help is appreciated.

I don't think you're overthinking anything. It sounds like there's a lot of underthinking and underplanning going on.
One question that jumps out at me: Fire protection/fire suppression for a large tire-storage facility.

If your rate tariff includes a demand charge, your past electric bills can answer the existing-demand question.

I would agree i don’t think they understand the bigger picture... in the existing building I’ve seen the electrical is a mess... I’ve seen no type of emergency egress, fire protection/prevention. Concrete work is done and I have yet to get a single set of prints on the building. I was told about it a week ago, and have lots of other work for the other 5 or 10 agronomy and grain plants that I do the maintenance and work for.... really needing some help on this one guys like I said I’m a young buck and got no one to ask any questions except this forum....

Call around a few engineering firms and find a local EE,
then get your bosses to approve a budget for you to get them as an EE consultant.
Even a one hour visit could make a huge difference.

I’ll see what they say last time I asked to do this I was basically laughed at.... is there anything the ahj can enforce? I’ve never seen another trade have anything inspected....

I do quite a bit of design-build work.

A job like this in my area is going to cost around $27k and I’ll charge 5% design fee to markup a drawing. Shouldn’t take more than half a day to complete the design. On a job like this I’d kick it over to my lighting supplier, tell them the illumination level I want and let them send me a lighting layout and fixture specification. Or just tell them the fixture budget and design around that.

It doesn't seem to me like a tire storage area is going to have a really serious issue with design. Presumably there's just a lot of shelving in aisles and you put enough lights over the aisles that you can see well enough. I don't think you're talking about a whole lot as far as anything above bare minimum.

I think your best bet is to write up a short description of what you plan to do submit that as part of your bid and if they don't like it they can pay more to change it.

Tires are combustible, but its probably more of a problem for the architects when there is that much combustible storage.

Different States have different rules, but in a lot of some places, you can't do design without having a valid PE license.

If I’m reading this correctly and the info is accurate, looks like you need a PE to design in Colorado....
