What are the four different situations that may occur that would allow a contractor to not bear the risk of unforeseen subsurface conditions?
What will be an ideal response?
The contractor will bear the risk of unforeseen subsurface conditions unless
(1) it can establish that it has relied on information furnished by the owner,
(2) the contract itself provided protection, (3) the owner did not disclose
information it should have disclosed, or (4) the cost of performance was

Follow the steps of the Systematic Approach of Section 14.4—that is, (1) identify the system, (2) determine whether the process is batch or rate, (3) construct a schematic diagram with inputs and outputs, (4) Label known material quantities or rates of flow and so on. In a mechanical coal-washing process, a portion of the inorganic sulfur and ash material in the mined coal can be removed. A feed stream to the process consists of 73 percent coal, 11 percent ash, 11 percent sulfur, and 5.0 percent water (to suppress dust). The clean coal side of the process consists of 88 percent coal, 6.0 percent sulfur, 3.0 percent ash, and 3.0 percent water. The refuse side consists of 32 percent sulfur, with the remainder being ash, coal, and water. If 8.0(10¹) metric tons per hour of clean coal
is required, determine the feed rate required for the mined coal and the composition of the refuse material. What will be an ideal response?
