LOAN AND BOUNDARY SURVEYS

0

Theory

Describe the contents of a typical loan survey and a boundary survey.

 

 

 

 

Differentiate between a loan survey and a boundary survey.

 

 

 

 

Describe the legal aspects of a loan versus a boundary survey.

 

 

 

Application

Given field data, draw a loan survey.

 

 

 

 

Given a complete set of field notes and courthouse and archives records, plat a boundary survey according to the State plat law.

 

 

 

AS-BUILTS

0

Theory

Describe the functions of as-built drawings.

 

 

 

 

List the typical contents of as-built drawings.

 

 

 

Application

Given all necessary field data, draft an as-built drawing.

 

 

 

PLAN AND PROFILE DRAWINGS

2

0

Theory

Describe the functions of a plan and profile drawing.

 

 

 

 

Discuss the fieldwork required to obtain the data for a plan and profile drawing.

 

 

 

 

Identify all common symbols used on plan and profile drawings.

 

 

 

 

Define "grade" and compute the grades of roads given total rise and run.

 

 

 

Application

Given a complete set of field data, plot a plan and choose a profile for the project that appears to balance out in cuts and fills.

 

 

 

CROSS-SECTIONS

2

0

Theory

Describe the four uses for earthwork quantity data.

 

 

 

 

Describe typical scales to which cross sections are plotted.

 

 

 

 

Discuss the relationship between the plan and profile drawing to the cross-sections.

 

 

 

Application

Given a plan and profile drawing, draw cross-sections at 25-50' intervals.

 

 

 

EARTH-WORK DETERMINATION

2

15

0

Theory

Calculate cross-sectional areas of cut and fill by the "counting squares" method.

 

 

 

 

Calculate cross-sectional areas of cut and fill by the geometric figure method.

 

 

 

 

Calculate cross-sectional areas of cut and fill by the use of a planimeter.

 

 

 

 

Calculate total cut and fill between two stations.

 

 

 

Application

Given a complete set of cross-sections, compute total cut and/or fill for the project.

 

 

 

GRADE DETERMINATION

1

10

0

Grade determination

Use the data obtained above to adjust the plane and grade of the profile of the project so that the earthwork approximately balances out.
