  • 1. Philadelphia Museum of Art Art Handling FacilityCarl D. Freedman, AIA Aegis Property GroupSeptember 17, 2012

2. PRESENTATION OF FACILITY ISSUES WITH THE DEVELOPMENT OF THENEW ART HANDLING FACILITYPROJECT DEVELOPMENT TEAM: 3. New vs. Existing Loading Dock 4. Level C 5. Sections APPROXIMATE LINE OFAPPROXIMATE EXISTING ROCKGRADENEW UTILITY TRENCH 6. VIBRATIONS, DEMOLITION &BLASTING Vibration standards established in preliminarytesting and research Equipment testing completed to determineequipment that could be used Test blasting competed to determine chargesizes and distances 7. VIBRATION STANDARDS Vibrations at the art work were limited to0.15 ppv for sustained vibrations (over 5second in duration) Normally, ppv values for blasting would bedouble sustained levels, but, it was decided tokeep the 0.15 ppv for all standards Normal ppv values for blasting near a buildingwould be between 2.0 ppv and 3.0 ppv 8. Machine Used to Cut Interior Rock and TrenchesWire on the Ground is for Vibration Testing 9. Test Blast Results Chart for 0.15 PPV we could blast up to 73 from the building 10. BLAST LAYOUT PLANPlan created to locate blastingsites and identify where reliefwould be availableOrange a green locations atbottom where additionalincremental tests done withthe first production blasts 11. Work Plan with blasting area, rock anchor installation, rock removal, electrical trenching 12. Vibra-Tech response to Work Plans with a vibration sensor location plan 13. BLASTING 14. Vibration Warning LevelVibration Monitoring results from Blast #11 15. INTERIOR DEMOLITION DUST CONTROL Early selective demolition on B Level beforeGMP was established 3D model of existing conditions created totrace existing lines Vibration and Environmental Controls Temporary shoring conditions Removal of existing columns 16. Structural Model 17. HVAC Model 18. Removal of Overburden Test Pit in Northwest cornerThis location was used to access the B Level for Interior Excavation 19. Temporary Storm Line During Excavation Section B1 Hammering of Concrete Slab 20. Section B1 Lowering of Floor Elevation 21. Interior Electrical Trenching Through Rock 22. Saw-cutting of Foundations and Retaining WallsColumn to be Placed on New Foundation 23. Temporary Shoring Structure for Column Foundation Removal 24. EXTERIOR EXCAVATION & DEMOLITION Stone wall deconstruction Historic Preservation Issues / Laser Cleaning Stone condition and deterioration Stone testing Overburden removal Rock removal process Blasting Sawing Grinding 25. Laser Cleaning 26. Removing the First Stone from Terrace Wall 27. Sandy debris Precursor of a small issue with a few of the existing stone. 28. Saw Cutting Terrace Wall 29. End Results of Terrace Wall Cut 30. ROCK EXCAVATION HIGHER ELEVATIONS 31. Installation of First Dewey-Dag Bar Rock Anchors 32. ROCK EXCAVATION CLOSE TO EXISTING BUILDING 33. This opening is the original access toB Level in the earlier slide.Temporary shoring micropile.Line of original footing. 34. LOGISTICS, WATERPROOFING & CONCRETE Logistics on a very tight site Excavation efforts were not complete, but,concrete needed to start to keep schedule Utility trench ran continuously through hardrock under the entire building addition Unique conditions for waterproofing andbuilding close to rock walls 35. ADDITIONAL BEAMTO BE INSTALLEDTO CARRY NEEDLEBEAMSTHIS AREA TO BEREMOVED FORFUTURE ELEVATORPermanent Shoring for Future Corridor Penetration 36. TIGHT SITE LOGISTICS POURING CONCRETE, EXCAVATING UTILITYTRENCH, ROCK REMOVAL AGAINST BUILDING 37. 3D SURVEY & MODELING Scanning less invasive Less costly than hand architectural orengineering surveying Accuracy with 1/8 Have imaging of your entire facility Can tailor the modeling completed to needs 38.
