The common problem related to mass concrete is thermal differential which may affect the structural integrity of concrete, With the aid of sketches, discuss this phenomenon,

Topic: Construction - Engineered Wood Products

(1 paragraph minimum please include reference if using one)

Discuss the significance and relevance in modern construction means and methods, of the use of "engineered wood products".

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?

4. Polymer concrete may be used for new construction or repairing of old concrete. What is the main advantage over ordinary concrete.

In designing and maintaining a long wastewater forcemain system or a water supply piping network, or another fluid system. what steps and activities can you think of that would save energy?

following your inspection of the off track environment, produce a short inspection report (min 400 words) which details your findings and explain the process for drainage inspections.
describe methods applied for the maintenance of track alignment

Describe the methods applied for the maintenance of track formation

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.

1.Under the lockout/tagout standard, what is the difference between an authorized employee and an affected employee? Include the citation for the OSHA standard where you found the answer to the question.

2.Other than the color, what is the difference between "Danger" signs and "Caution" signs? Include the citation for the OSHA standard where you found the answer to the question

Let's just say some random guy approaches you on the street asking what an "influence line" is. He claims to be a structural engineer but has never heard of such a thing. How would you explain it to him? Try to explain in laymen's terms while still appearing competent

produce and explain five types panel used for slab construction. Annotated sketches can be made to support the answers. EV,10

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?

Design a short square tied column to carry a factored axial load of 1300k and a factored moment of 550kft. Place the reinforcement uniformly around the column. Design the ties. Assume interior exposure, f’c = 4000psi, fy = 60,000psi.

If you needed to reduce deflection in a loaded aluminum rectangular box beam in your structural design, which of the following variables would you INCREASE? :

-Length

-Outer width

-Outer height

-Inner width

-Inner height

Which would be the MOST effective in reducing deflection?

What material could you substitute for aluminum in your design to decrease deflection? Why?

Please explain in detail the effects of different moisture conditions (saturated/dry) in soil to rainfall-runoff relationships? Expound on the concepts of rainfall volume, runoff volume, runoff coefficient, and interflow.
