21 Jan 09 20:55If 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.

21 Jan 09 23:38My 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.

22 Jan 09 08:13David,
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.

22 Jan 09 09:08I'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.(Chemical)
22 Jan 09 09:54I 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$600,000This would be for new pipe in an existing chemical plant that has some existing pipe racks, so minimum support would be needed.
Good luck,

22 Jan 09 10:29latexman - 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...
(Mechanical)
22 Jan 09 10:32I 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.
(Mechanical)
22 Jan 09 12:57I tend to agree more with LOUDDOG...The $600,000 figure seems too highHis 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 ??-MJC

insulated, 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.The number I started with was for 316 SSinsulated, 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.

22 Jan 09 18:56This 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.

26 Jan 09 11:55Where 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.

for pipeline companies)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.**********************"Pumping accounts for 20% of the world's energy used by electric motors and 25-50% of the total electrical energy usage in certain industrial facilities."-DOE statistic (Note: Make thatfor pipeline companies) http://virtualpipeline.spaces.live.com/

27 Jan 09 12:34pipes 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?

We tend to take for granted the plumbing pipes in our homes (until and unless they break, of course). But if you&#;re building, adding onto or renovating a home &#; especially an older one &#; the type of pipe is something you may well have to consider.
Not all pipes are created equally, and they certainly don&#;t have the same price tag. And that, of course, begs the question: how much do pipes cost? The price of pipes ranges from about $0.40 to $10.00 per linear foot, depending on the type of pipe material. Metal pipes cost more than plastic ones as a general rule.
The cost to replace plumbing will depend on which type of pipe material you choose and the rate for installation in your area. Some pipes are easier to install than others. Bear in mind that installation may require the removal and replacement of any drywall or flooring, too.
Still, the bulk of your costs are likely to come from the pipes themselves. Your primary choices are:
Before we look at the pros and cons of the different types, let&#;s talk about the costs to install them.
The right pipe for your project should consider the durability and longevity you require, plus the cost of materials and labor. Less flexible and heavier pipes can be more expensive to install because they require expertise and are more complex to work with, but they might last longer.
When you&#;re budgeting for your overall plumbing pipe cost, be ready to pay $1-2 per linear foot for labor. Installing metal pipes generally costs more than plastic.
Material Material Cost Per Linear Foot Material and Labor Cost Per Linear Foot Common Uses What You Should Know Copper $2&#;$8 $3-$10 High-end plumbing projects, all water temperatures The gold standard in plumbing pipes, can last up to 100 years PEX $0.40&#;$2 $1.50-$3 Any, including in-floor heating Leak resistant, designed to last long, affordable CPVC $0.50&#;$1 $1.40-$4 Most water temperatures, budget projects Can last 50&#;70 years, needs to be fitted precisely to avoid leaks Galvanized Steel ~$8 $9-$10 Older homes, high-pressure plumbing Shorter lifespan (~40 years) Cast Iron $2&#;$10 $3-$12 Sewage, drainage Likely to corrode ABS $1&#;$10 $3&#;$12 (for indoor plumbing costs, higher for sewage projects) Sewage, drainage, venting Dangerous for drinking water, degrades in sunlightWhat it is: Copper is sort of the gold standard in pipes. Known for its durability, it can last as long as 100 years. Copper pipes are naturally resistant to bacteria and are less likely to break down if exposed to UV rays. As a result, the cost of copper pipe per foot exceeds a lot of other piping options. Many brass pipes, which are not as common, are also composed primarily of copper with slightly less durability.
Cost: $2&#;8 per linear foot
What it is: Chlorinated polyvinyl chloride (CPVC) piping is one of the oldest types of modern pipes, in use since at least the s. It&#;s the cousin of PVC piping, made of very similar material but altered with chlorine to make it better able to withstand a wider range of temperatures, especially on the high end. This type of plastic pipe has thick walls that can be used for both cold and hot water lines (PVC only works well for unheated water), and it&#;s extremely well-priced. Unfortunately, there are some drawbacks in exchange for that low plumbing pipe cost. CPVC can be more likely to leak, especially if not fitted precisely at the time of installation. It also has a shorter lifespan &#; about 50-70 years.
Cost: $0.50&#;$1 per linear foot
What it is: Cross-linked polyethylene pipes (PEX) are highly flexible, both literally and figuratively. They can be used with other types of pipes, making them ideal for repairs or complex system replacements. Developed in the s, they are a relatively new type of piping material that is quite durable &#; theoretically about on a par with copper, though the exact lifespan is yet unknown &#; and unlikely to leak. In other words, if you&#;re looking for something with a long lifespan without the high cost of copper pipe per foot, PEX is a solid option.
Cost: $0.40&#;$2 per linear foot
What it is: Galvanized steel pipes, sometimes called just galvanized pipes, are most likely to be found in homes that are 40 years old or more. Made from steel dipped in a zinc coating, they used to be quite popular &#; a safer alternative to lead, it was once thought. While their zinc coating survives, the pipes can be quite durable; however, once their coating corrodes over time, the exposed steel is very likely to rust and become unstable. Add the fact that the price of pipes made from galvanized steel is fairly high and it&#;s no surprise these aren&#;t commonly used anymore.
Cost: About $8 per linear foot
What it is: Cast iron pipes were the standard until about the s, when steel and PCVC began to take over. Their walls are thicker than that of steel pipes, and they may also sport a protective lining. Unfortunately, while strong, cast iron pipes are not flexible and are susceptible to rust. While these pipes may still be an optimal choice for sewage and drainage, nowadays they are unlikely to be recommended for a residence because they are heavier and more likely to become corroded than the more malleable materials that are now available.
Cost: $2&#;10 per linear foot
What it is: Pipes made from acrylonitrile butadiene styrene &#; or ABS, for short &#; are known for their ability to withstand extreme hot or cold temperatures and pressure. Usually colored black, these plastic pipes work best for drainage, sewage and ventilation. They shouldn&#;t connect to your house&#;s drinking water supply, because they contain Bisphenol A (BPA), a chemical that enhances their durability, but can cause cancer when consumed. ABS pipes are typically installed underground to carry waste away from homes.
Cost: $1&#;$10

The bad boys
You might notice we left two types of pipes off this list: lead and polybutylene (PB). Lead &#; primarily used from &#; &#; is a toxic metal that can leach into your water, and PB pipes &#; mostly used from &#; &#; have a high risk of rupturing. If you encounter these types of pipes in your home, they need replacing, and fast.
Nothing lasts forever, including your home&#;s plumbing system. Whether you&#;re ready to replace outdated pipes with money from a home equity loan or you&#;re shopping your options because your homeowners insurance will pay to repair a burst pipe, you won&#;t be left wanting for choices. Beyond the price of pipes, you should also consider the use case, labor cost and lifespan.
It&#;s widely recommended that, because of corrosion issues, homeowners replace galvanized steel and cast iron pipes with either traditional copper (which costs the most, but also comes with a very long lifespan) or one of the newer plastic options (PEX and CPVC). Of those two, CPVC is cheaper and offers lots of bang for the plumbing buck, but PEX is widely praised for offering copper&#;s durability at close-to-CPVC prices &#; plus its own characteristic flexibility.
