13  Bridge Staging Areas ◦ Space requirements ◦ Geotechnical investigation ◦ Level terrain for travel Path ◦ Positive drainage ◦ Environmental considerations 13 Rawson Bridge Staging – West Span Rawson Bridge Staging – East Span

14  Shoring Towers ◦ Two (2) span 45W girder bridge ◦ Timber crane pads ◦ Steel shore towers ◦ Steel header ◦ Anchorage for lateral loads and stability 14 Shoring Tower – West Span Shoring Tower – East Span

15  Self Propelled Modular Transporter (SPMT) ◦ Ground improvements on travel path ◦ Steel plates for turning radius ◦ Space for bracing and existing shore towers ◦ 138’ feet wide ◦ 95’ feet long 15

16  SPMT ◦ Heavy lift contractor ◦ Submittal reviews ◦ 35 semi-loads of equipment ◦ Site access ◦ Assembled in 48 hours  Public viewing area 16

17  Pre-Move Deck Crack Inspection ◦ Deflection monitoring during bridge Move ◦ Post move crack inspection ◦ Pier closure pours ◦ May 28 th to June 23 rd closure window 17

18  Pre-cast pier construction ◦ Driven pile and cast in place pile cap ◦ Detailed bar steel placement with template ◦ High early strength masonry 18

19  Pre-cast concrete columns  High strength bar steel couplers  Footing to column connection  Column to precast cap connection  8000 psi non shrink grout 19

20  Pre-cast pier construction ◦ Pre-cast concrete cap ◦ Sections up to 45 tons – Two (2) crane pick ◦ Grouted bar coupler Connection to columns ◦ Tight construction tolerances ◦ Survey control 20

21  Pre-cast pier construction  Lessons learned: ◦ Detail additional room for bar couplers ◦ Comprehensive survey control ◦ Steel templates for bar steel ◦ Match cast pre-cast elements 21

22  Keys to Project Success ◦ Public outreach and involvement ◦ Close coordination with prime and heavy lifter ◦ Travel path preparation and planning ◦ Project partnering with stakeholders 22
