I`m currently looking at the Electrical Cost Data 2012 - under 26 22 13.10 (line 5670) 15kV/480V Dry Transformer and the suggested cost is 79000$ compared to the Department of Energy recent study average of 40000$ for exactly the same type and size.
What was considered in that item that could explain that difference? My in-house estimators and I are interested in learning more about this.
The average number given in the latest technical support document published by US Department of Energy concerning transformers (dry and wet) was 46,484$ for a 1500 kVA Dry Transformer 15kV Primary 480Y/277V Secondary 95 kV BIL with low at 33,000$ and high at 78,859$.
The main factor is the winding material, at the top of the list are the copper-copper windings and at the bottom, mainly the Alu-Alu windings. The same thing for the 4.16 kV Primary at 1500 kVA.
Now a day, the aluminum windings are the norm and the copper windings are offered by some suppliers only as an option.read answer
I have an open carport on the side of my house and I want to enclose it into a garage.
This means I will have a wall built on the existing concrete slab.
What is the minimum footing for a concrete wall in Tennessee and do I need to get a local permit?read answer
We are currently in the process of designing a new 2 story, 9,000 square foot retail building. The previous building was damaged by a tornado, and subsequently torn down. The project will go out to bid to 8 general contractors.
My question is about "standard" general contractor rates. Obviously, their profit is going to be a percentage of the "cost of construction." What is a currently competitive percentage, as we begin to review bids?
Thank you!read answer
A twitter follower responded to RCD Chief Economist Bernard Markstein's recent article Construction Spending Inches up in March.
Compare March data to expected based on any year in last 8 not the Seasonally Adjusted Annual Rate (SAAR) and see that we just had the worst March in 8 years. Isn't it down not up?read answer
