The study of Engineering Economics in Civil Engineering, also known generally as engineering economics, or alternatively engineering economy, is a subset of economics, more specifically, microeconomics. It is defined as a "guide for the economic selection among technically feasible alternatives for the purpose of a rational allocation of scarce ...
where C is total cost, a b and k are constants, and x is the variable number of units produced. There are a great number of cost analysis formulas, each for particular situations and are warranted by the policies of the company in question, or the preferences of the engineer at hand. [7]
A Allocation of costs is the transfer of costs from one cost item to one or more other cost items. Allowance - a value in an estimate to cover the cost of known but not yet fully defined work. As-sold estimate - the estimate which matches the agreed items and price for the project scope. B Basis of estimate (BOE) - a document which describes the scope basis, pricing basis, methods ...

In earthmoving , cut and fill is the process of constructing a railway , road or canal whereby the amount of material from cuts roughly matches the amount of fill ...
If its economic base is concentrated in sectors that are growing, then it is in good shape. Methodologically, economic base analysis views the region as if it were a small nation and uses notions of relative and comparative advantage from international trade theory (Charles Tiebout 1963). In a sense, the activity is macroeconomics "written ...
Benefit–cost analysis – Cost–benefit analysis (CBA), sometimes called benefit costs analysis (BCA), is a systematic approach to estimating the strengths and weaknesses of alternatives used to determine options which provide the best approach to achieving benefits while preserving savings (for example, in transactions, activities, and ...
Section through railway track and foundation showing the sub-grade. Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, [1] for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage.
Depending on the slope of the hill, the parallel trenches can be closer or further from one another. Manually dug trenches are smaller. Machine dug trenches can be deeper. The dimensions, and the format of the trench should correspond to the local climate and soil conditions. The trench should be big enough to keep all the water; no water ...
