SLC Runway 34 R-16 L Problem: Base cans in the way Existing Grade Elevation New Grade Challenge: • Can’t raise runway too much • Fix runway humps • Overlay as close to 4” as possible • Minimize disruption to operation or number of base cans removed Airfield Lighting Design and Construction R/W CTL #13 R/W CTL #12 R/W CTL #11 R/W CTL #10 R/W CTL #9 R/W CTL #8 R/W CTL #7 R/W CTL #6 R/W CTL #5 R/W CTL #4 R/W CTL #3 R/W CTL #2 Milled Surface R/W CTL #1 Base Can Height

SLC Runway 34 R-16 L Solution: Revise Profile Existing Grade Runway slightly raised in certain spots by no more than 1” New Grade Result: • Schedule impact significantly reduced • 350 fewer cans were removed, approximately $400 k savings • Efficient milling operation Airfield Lighting Design and Construction R/W CTL #13 R/W CTL #12 R/W CTL #11 R/W CTL #9 R/W CTL #8 R/W CTL #7 R/W CTL #6 R/W CTL #5 R/W CTL #4 R/W CTL #3 R/W CTL #2 R/W CTL #1 Base Can Height R/W CTL #10 Elevation Milled Surface
