For the estimation of the new construction of the civil structures, we need the Basic Rates, depending on the location, type of material required, and the availability of the material.
The basic rates are calculated by adding transportation cost, national and loacal taxes on the base rate inwhich the material is purchased from the original source.
Since the question is similar to another one asked about power plant construction, I thought it might be helpful to answer it here too. I hope it helps:
"The total cost of a project will be a combination of estimated costs from literature, mathematical formulas from reliable references (e.g. NREL), and information gathered from various companies that have built similar technology.
I give you an example on the cost of energy(COE) that you certainly can use it for other applications:
The COE is important in cost analysis for energy production since it is the cost seen by the consumers, given by:
COE=((DRFxICC)+O&M+LRC+Fees)/AEP
where ICC is the Initial Capital Cost, O&M is the operations and maintenance costs, LRC is the levelized replacement costs, AEP is the annual energy production, Fees are the annual insurance; warrantees; etc., and DRF is the discount rate factor. The DRF is given as:
DRF=d/(1-1⁄(1+d)^N )×(1-T*PVDEP)/(1-T)
where d is the discount rate, N is the analysis period, T is the marginal income tax rate, and PVDEP is the present value of deprecation.
Having this COE known, one can have a good estimation on the projected (total) cost. The projected revenue for this case would be how much money is saved if we for example replace a coal power plant with a renewable energy source; or how much it will be saved after having a new power plant that reduces importing energy form other countries or sources.
You can follow a similar concept to estimate the projected costs and projected revenue."
