Price of piping per foot?? 1

[rmw]

If someone popped into your cube/office/space and asked 'what is the installed price per foot for 500ft of 6" schedule 40 steel pipe insulated, lagged and heat traced, supported and anchored with ~10 elbows, welded construction' what would your response be knowing no more than that. This is just for a ball park number.

My response would be "get out of my cube", possibly followed by "never come back".

A 500 ft job is nearly impossible to estimate with rules of thumb. You need to know what this hour's steel price is, where the job is (mobilization can easily be 25% of the job cost), etc. Your "insulated, lagged and heat traced, supported and anchored" comment sounds like you're inside a plant fence so again, any rules of thumb would be absolutely plant specific.

I recently looked at the records on a job that one client built for $10k/inch-mile and the following week I looked at another clients records and saw a kind of similar job (a bit shorter) that was $85k/inch mile.

David,

Take time to glance up and see my backside leaving your cube. But thanks for the numbers anyway because it does define a range of "ball park" for me which is better than the "ball park" numbers I have in my head from way too many years ago to use now.

Regards,

I've never had much luck with Rules of Thumb estimates for projects less that 2 miles. 500 ft projects need to be costed with liberal Kentucky Windage. I always have to keep in mind that while management claims to want precision what the really want is not to overrun the budget. I've gotten into the habbit of doing my best estimate (including a contingency) and then adding my plus/minus to it (i.e., if I'm asked fot a +/- 10% number I'll add 10% to every line item before submitting it). That gives me a +0 -20% number, but I've never gotten in trouble for being under budget. None of the projects that I've been called in to do have been tight enough in their economics that this budget inflation has changed the decision.

I know I'll get flamed for this, but I'd guess about US$100/ft for 1" Sch. 40, scale it up based on weight/ft, and then round up to 1 sig. fig. That'd be:

100 x 18.97/1.68 x 500 ft. = US$600,000

This would be for new pipe in an existing chemical plant that has some existing pipe racks, so minimum support would be needed.

Good luck,

latexman - you're right - flame 1) you have scaled up both the material and installation cost by the same factor. As the material cost is only a fraction of the total installed price, and the labor cost to install pipe does not increase in a linear manner with the weight of the pipe, you have grossly overestimated the labor cost to install. Your estimated cost of $1,200 per LF is way high. However, management should be happy that the construction will come in under budget...

I would say that number is way to high. Assuming you piles are not included in the price, just a few feet of beam for supports.... I would say $60,000.

 

[MJCronin]

I tend to agree more with LOUDDOG...

The $600,000 figure seems too high

His approximate cost is $60,000/500 = $120/ft...and that seems low.

My guess is between $150 and $200 per foot (I also assume carbon steel piping and pipe supports by others)...so...

I say between $75,000 and $100,000...

Anybody else ??

The number I started with was for 316 SS uninsulated, but decided to call it equal to CS insulated. Right, wrong, or indifferent, there was no risk to me, so I used what I had. It did get the ball rolling though.

Good luck,
Latexman

$128,000 without contingencies.

This has been a good response and I appreciate it. First, it would be a greenfield project meaning that there are no existing supports and would have to be added (materials and engineering) to new construction or as an addition to an existing plant, power plant in this case, not chemical.

The number that my most astute client always threw out way back when (late '70's to early '80's) was $100.00/ft and that wasn't heat traced but would have included supports. Based on the material costs alone for other things, I would tend to double that now 30 years later.

Pennpiper where are you when I need you? I looked for something on your site as well.

Thanks for all the contributions and if anyone has anymore to add, jump in.

Where is it at? Downtown Baghdad might be a tad more expensive than rural Oklahoma.

Too many variables to give anything other than a +/- 100% number.

Just the pipe will run you are $35K - if I was forced at gun point, I'd peg it around $250K TIC. Wouldn't argue much with $100K; $600K might raise some "how come" questions.

I think its ony halfway accurate on projects involving 50 miles or more, not counting end tie-ins, crossings or valve stations. To include those, maybe you need 100 miles to get a reasonable average "estimator", but then you probably have a pump station somewhere.

pipes in plants, I estimate at $2,000,000/mile, doesn't matter much about size as mob and demob cost dictate it all, so, $190,000 US. Now you can decide, DO I REALLY NEED that 500 feet?
