this is regarding a construction safety course under the civil engineering degree plan, thanks

2. You are a recent college graduate, and this is your first real job. You are the assistant director of safety for Rayster Construction, Inc. (RCI). Your job today is to conduct preoperation inspections of the company’s two cranes that are being used to construct a bridge across a small bay. As you begin your first inspection, the crane operator—who has worked for RCI for 25 years—brushes past you and starts the crane’s engine. He says, “Get out of the way, kid. This crane is just fine. It doesn’t need inspecting. You are holding up my work.” This crane operator has an excellent safety record, as does RCI in general. How should you handle this situation?

Le Corbusier was fascinated by certain engineering objects. This interest was well expressed in his book Towards a new Architecture (1923) and well captured by his definition of house as “a machine for living in”. In a similar vein, Walter Gropius outlined the new orientation of his school as “the Bauhaus believes the machine to be our modern medium of design and seeks to come to terms with it.”

What do these two statements mean? What is the relation between ‘architecture’ and ‘machine’ as stated by these two architects? Explain your answer by using at least one building by Le Corbusier and one building by Walter Gropius.

2. A wastewater treatment plant discharges an effluent containing 3 mg/L of dissolved oxygen to a river that has a dissolved-oxygen concentration of 6 mg/L upstream of the discharge. The saturation dissolved oxygen for the river is 8 mg/L. Assume that the WWTP discharge rate represents 80% of the river flow rate which travels 0.5 km in an hour. The CBOD5 of the river is 5 mg/L with a decay coefficient of 0.25/day. The reaeration coefficient of the river is 0.5/day. What is the location of the critical point: (a) in time; (b) in distance? (c) Why is critical dissolved oxygen a concern and (d) what are the ways to avoid it?
