Answer:
c) site preparation
Explanation:
A construction process can be defined as a series of important physical events (processes) that must be accomplished during the execution of a construction project.
Generally, in the construction of any physical asset such as offices, hospitals, schools, stadiums etc, the first step of the construction process is site preparation. Site preparation refers to processes such as clearing, blasting, levelling, landfilling, surveying, cutting, excavating and demolition of all unwanted objects on a piece of land, so as to make it ready for use.
This ultimately implies that, site preparation should be the first task to be accomplished in the construction process.
Hence, the construction process typically begins with site preparation before other activities such as the laying of foundation can be done.
Additionally, construction costs can be defined as the overall costs associated with the development of a built asset, project or property. The construction costs is classified into two (2) main categories and these are; capital and operational costs.

Answer:
reservoir is 727°C, then low temperature
Explanation:
Efficiency for any Heat engine = Work done by engine / Heat provided to the engine
Also, for a carnot engine derived formula for Carnot Engine
= 1- T2/T1
Where, T2 = sink reservoir temperature
and T1 = source reservoir temperature
727° C = 1000 K
So, 0.75 = 1-T2 / 1000
So, T2 = 1000*0.25 = 250 K = -23 Kelvin
