1 New Challenges for Army Combat Engineers: Bomb Damage Assessment, Fire Damage Assessment, Evaluation of Diminished Capacity, and Developing New Strategies for Short, Medium and Long-term Mitigation/Repair J. David Rogers Natural Hazards Mitigation Center University of Missouri-Rolla

2 Tikrit Bridge Demolition by Iraqi Forces

3 Views From the Bridge

4 Bomb Damage Assessment Critical structures damaged by bombs and Improvised Explosive Devices must be evaluated for capacity. No clear cut methodologies or established protocol is presently included in combat engineering training syllabus to educate junior officers how to go about these tasks.

5 Bomb and fire-damaged bridge decks required immediate evaluation of diminished capacity. Then, decisions about what kinds of short, medium or long-term measures to effect repairs. At present, long-term repairs are generally turned over to civilian contractors.

6 Fire Damage Assessment

7 The traditional role of combat engineers has been Short-term term combat bridging only there long enough to win the battles

8 This view shows the longest floating river bridge assembled in a combat theater since World War II, across the Tigris River in Tikrit. A typical pontoon treadway bridge can be erected in just 6 hours, but would require two multi-role bridge companies, 36 Bridge Erection Boats, 80 Assault Float Bridge sections and 24/7 operability of the boats.

9 Tikrit Highway Bridge Assessment & Temporary Repairs

10 Temporary Bridge Solution

11 East Bound Traffic

12 Mabey Johnson Bridge end connections

13 Pier 8, east end Damaged Pier 7, west end

14 PIER 7 FRONT VIEW NORTH 1D MEASURE EXPANSION OF CRACKS 2D 3D 4D *Mostly surface damage cracks - do not require daily measurement

15 Bridge Pier Cap w/ Cantilever ends PIER 7 TOP VIEW Bridge Beam & MJ Bearing area MEASURE THE DEGREE OF DEFLECTION BETWEEN THE EAST AND WEST SIDE OF THE CANTILEVER (MAY REQUIRE SURVEY EQUIPMENT) 1E East bound traffic West bound traffic Using MJs 1F Bridge Pier 2F *Critical crack requires daily measurement MEASURE THE EXPANSION OF THE CRACK ALONG THE CAP OF THE CANTILEVER

16 PIER 7 SIDE VIEW Bridge super structure MEASURE DEFLECTION OF I-BEAM AT THE END OF THE CANTILEVER FOR INDICATION OF STRESS 1B 1A MEASURE THE EXPANSION OF THE CRACK ALONG THE END OF THE CANTILEVER 2A *Crack will not grow without crack on top of the pier cap growing Do not require daily measurement

17 Bridge Pier Cap w/ Cantilever ends PIER 7 BOTTOM VIEW Bridge Pier *Crack will not grow without crack on top of the pier cap growing Do not require daily measurement 1C MEASURE THE DISTANCE BETWEEN THE ENDS OR THE CRACKS UNDERNEATH THE CANTILEVER

18 Mabey Johnson spans placed on upstream side of tail span gaps on the Tikrit Bridge across the Tigris River. Note repair of Pier 7.
