 1. Pipeline 



a. Upland areas (soils not waterlogged) 



1) Surveying (2-10 km/day) 



a) Survey crew entry to location 



b) Minor vegetation clearing 



c) Measuring and staking 



d) Survey crew exit 



2) Clearing (0.25-2 km/day) 



a) Equipment entry - bulldozer, trucks, crew 



b) Dozers clear vegetation along entire length, width 

 of right of way 



c) Vegetation stacked and burned 



d) Dozers fill and grade surface 



e) Surface prepared for vehicular traffic 

 (1) Additional fill 



(2) Compaction 



I 



(3) Temporary board crossings constructed 



(4) Surfacing material brought in and placed 

 where needed 



f) Build cattleguards, gates, and reroute fences 



g) Equipment exit 



3) Ditching (spread - Phases 3-10 - 0.25-3 km/day) 



a) Equipment entry - ditcher, dozer, ripperbackhoe, 

 dragline, trucks, compressed airdrills, roadboring 

 machine 



b) In areas with rocks in soil, ripper moves through 



c) Backhoe and/or dragline removes dirt and rock 

 and stacks in bank along one side of ditch 



d) Ditcher excavates ditch, costs spoil to one side 

 in bank 



e) Tunnel under road, railroad, obstruction 



(1) Boring machine transported to site 



(2) Hole casing transported 



(3) Boring machine supported by side-boom tractors 

 puts hole beneath obstruction 



f) Large rock or obstruction 



(1) Dragline removes rocks, or 



(2) Compressed air drill bores into rock or 

 obstruction 



(3) Explosive charge used to split rock, dragline, 

 or backhoe removes 



g) Ditch periodically pumped if water table is high 

 or have high rains - pump to adjacent land areas 



4) Pipe stringing 



a) Trucks bring pipe to area adjacent to ditch 



b) Unloaded by side boom tractors 



c) Trucks exit site 



5) Pipe bending 



a) Side-boom tractors, bending shoes, and bending 

 machines moved to spot where pipes will be bent 



b) After bending, pipes may be moved to proper site 

 by ditch by truck or side-boom tractor
