ROUTE SURVEYS The  term  route  survey   refers  to  surveys necessary  for  the  location  and  construction  oflines  of  transportation  or  communication  that continue  across  country  for  some  distance,  such as   highways,   railroads,   open-conduit   systems, pipelines,  and  power  lines.  Generally,  the  pre- liminary  survey  for  this  work  takes  the  form  of a topographic survey. In the final stage, the work may  consist  of  the  following: 

  1.  Locating  the  center  line,  usually  marked  by stakes at 100-ft intervals called stations 
  2.  Determining  elevations  along  and  acrossthe   center   line   for   plotting   profile   and   cross sections
  3. Plotting the profile and cross sections and fixing the grades 
  4. Computing the volumes of earthwork andpreparing a mass diagram 
  5. Staking out the extremities for cuts and fills 
  6. Determining drainage areas to be used in the  design  of  ditches  and  culverts 
  7. Laying out structures, such as bridges and culverts 
  8.  Locating  right-of-way  boundaries,  as  well as  staking  out  fence  lines,  if  necessary.
