A bridge over a fresh water river is in need of repair. It is located in a geographical area that is only accessible by foot, so a repair crew needs to carry out the repairs without the use of heavy machinery. The focus of the repair is a part of a footing. The footing is in still water and is 8 m below the surface of the river. One member of the repair team noticed that a boulder must have been dislodged from the river bank and is blocking the repair site. The diameter of the boulder was is about 30 cm. The geographical region is known to have granite rock formations. How many divers would it take to lift the boulder and move it away from the footing?

Question

A bridge over a fresh water river is in need of repair. It is located in a geographical area that is only accessible by
foot, so a repair crew needs to carry out the repairs without the use of heavy machinery. The focus of the repair is a
part of a footing. The footing is in still water and is 8 m below the surface of the river. One member of the repair
team noticed that a boulder must have been dislodged from the river bank and is blocking the repair site. The
diameter of the boulder was is about 30 cm. The geographical region is known to have granite rock formations. How
many divers would it take to lift the boulder and move it away from the footing?

A twenty-story hospital building with a 400 ft x 200 ft footprint is to be built on a site underlain by fill over glacial sands. The building will have a 25-ft deep basement and will probably be supported on either a mat foundation located 5 ft below the bottom of the basement, or a deep foundation extending about 100 ft below the bottom of the basement. The groundwater table is about 30 ft below the ground surface and bedrock is about 120 ft below the ground surface. There are no accessibility problems at this site. (a) How many exploratory borings will be required as per NYC Code, and to what depths should they be drilled? (b) How would you obtain groundwater data? Explain your answer.
