Describe the types of projects that would be referred to as heavy construction. Explain what entities are usually responsible for such projects and why.

What will be an ideal response?


Heavy construction is the term used for larger infrastructure projects such as highways, bridges, canals, dams, subways, tunnels, utility piping systems, water control construction, and communications networks. Heavy construction projects are usually financed by governmental agencies and other institutions or are incorporated into master plans (such as universities) to serve the public good.

A building is losing heat to the surrounding air. The inside walls of the building are maintained at 22.0°C, and the walls have a thermal conductivity of 0.50 W/m-K. The wall thickness is 0.10 m, and the outside wall temperature is held at 2.0°C. The air temperature is -10.0°C. Consider the emissivity of the outside of the walls to be 0.85. Calculate the conductive heat flux and the radiative heat flux. Considering that the heat flux entering the outside of the wall from the inside must balance the heat flux leaving the outside of the wall via convection and radiation, determine the necessary convective heat transfer coefficient of the air passing over the outside wall.

Given: To = Ts = 2°C = 275 K; Tsurr = -10°C = 263 K; Ti = 22.0°C = 295 K; ?x = 0.10 m; ? = 0.85; ? = 0.50 W/m-K What will be an ideal response?
