  37. Pullbox/Splicebox/MH Req’s& Constraints

  38. Niche Req’s & Adjustment Constraints No Vertical Adjustments Permitted Conduit Stubups Must Match Niche Location

  39. Special Issues: SME

  40. Special Issues: SME

  41. Special Issues: SHO

  42. Sierra Lundy Tunnel • Design coordination

  43. HOW THIS AFFECTS YOU SSH

  44. Guideway At-Grade • Drainage coordination (w/ 34.5kV & cable trough) • Structures coordination (w/ 34.5kV & cable trough installation) • Be gentle (w/ stubups, trough & boxes) • When DC stubups go in, contact rail positioning is set

  45. Trench • Adjustments to crosswalks, niches, invert height, contact rail, and track forms will directly impact systems design & construction • Systems/Electrical conduit is everywhere, call before you pour. • We can adjust our routing, but end points are often fixed • High level of coordination required at trench limits, station ends, overcrossings, and SME & SHO • Niches and conduit must be properly aligned

  46. Aerial • Window cutouts are fixed • Sleeves in the structure have to be moved if contact rail design changes • Traction power, communications, and train control conduit will transfer from the aerial to the ground on the north and south aerial structure

  47. Wayside • Utility coordination • Precisely level, coordinated foundations are key

  48. Stations • We’re everywhere. • Guideway/Stations interfaces will be key

  49. Questions
