What is Preliminary Engineering?
Preliminary Engineering (PE) includes identifying additional project design detail, taking into consideration the physical needs of the passenger rail technology used, and the geometry of the terrain along the identified route. The plans will be developed to a 10 percent level of detail initially, to confirm the location and to provide the environmental team with a defined footprint for assessing the environmental impacts. At the end of this phase, pending approval from the Federal Transit Administration, plans will provide up to a 30 percent level of detail, which will help determine more precise cost estimates.
