I would think the first question you should reply with is Do you want a matchbox scale or a full scale model??
Your inquiry is meaningless!!!
Do you have 5 miles of 24 XX-stg pipe or do you have 300 feet of 2 in sch 40 pipe??
Are you replacing in kind?/
What obstacles are in the way to get rig in??
How 'brown' is the site??
Give us a CLUE!
thanks for your reply, I´ll tried to explain it better.
it`s just a power plant dismantling projet, but I don´t need the exact budget, I´d like just any ratios about the general cost of it because I just need a general budget to get a urbanistic licence according to the laws on the place where the plant will be built.
I don´t know if I gave a clue to you, I´ve tried it. By the way if you wanna build a car don´t forget that it have 4 wheel and these must spin.
ok since that is all you are going to give. I woud say it is going to cost you about 75% of the labor costs that it is going to cost you to put in the new pipe. WAG!
johnmam,
Demolition of plant is covered in a British Standard which outlines the requirements. The costs of producing documentation should not be forgotten as these can be exhaustive. In the UK you cannot just go in and "cut and carve out piping systems without providing the necessary paperwork to provide to the next contractor who is going to work on the site.
Also on the car - the wheels only need to spin when the car moves - spinning wheels when the car is stopped is not good practice - tyres wear out and it may mean the brakes don't work.
I don't know your jurisdiction but if the plant has any age you may have to deal with asbestos exposure. This will normally more than triple your cost.
In the US if you don't properly remove ever little shred of asbestos it can get very expensive in the form of fines from the environmental people.
Case in point:
We had properly removed all pipe and process components in process building and a crew was starting to demo the building when state and federal environmental people paid a call. As they stepped out of their car they spotted a 12" asbestos tubing sleeve and jumped back in their car and left. we had to bring back the asbestos abatement people to resurvey the building and at the same time received a nice fine ($50,000). Both the state and federal got piece of us.
- List as detailed as possible all cost factors (mainly rigging, work, transport,depsit cost or gain, environmental,local requirements, cost to overcome time limits, tool or equipment renting, power and light, cleaning, derigging etc. etc.)
- Use excel, and as detailed as possible guesstimate each post as 'cheapest, absolutely not under' and 'worst case, could cost as much as'. Detailling according to accuracy level required.
- Add sum of both columns, divide by two.
- Add 10-20% for unforeseen.
- Check if result seems reasonable.
This has been working well for me both in work situations for larger projects, and privately.
