CONSTRUCTION SEQUENCING THE FOLLOWING CONSTRUCTION SEQUENCING IS SUGGESTED: 1. INSTALL A NEW 2x10 WALL ON A NEW CONCRETE FOOTING IN THE BASEMENT INSTALL A NEW 2x10 WALL ON A NEW CONCRETE FOOTING IN THE BASEMENT OF 143/147. 2. REINFORCE THE CONNECTION OF THE EXISTING TEMPORARY SHORING WALLS REINFORCE THE CONNECTION OF THE EXISTING TEMPORARY SHORING WALLS TO THE EXISTING MAIN FRAMING ELEMENTS OF 143/147. 3. FIELD LOCATE NEW SHEARWALL LOCATIONS AT 6'-0" O.C. MAXIMUM SPACING FIELD LOCATE NEW SHEARWALL LOCATIONS AT 6'-0" O.C. MAXIMUM SPACING TO ALLOW FOR VERTICAL ALIGNMENT OF THE SHEARWALLS FROM THE BASEMENT TO THE ATTIC. THIS MAY REQUIRE SELECTIVE DEMOLITION OF INTERIOR PARTITIONS. 4. INSTALL NEW STRUCTURAL STEEL SHORING/BRACING ON THE EXTERIOR, NEW INSTALL NEW STRUCTURAL STEEL SHORING/BRACING ON THE EXTERIOR, NEW TIE RODS THROUGH THE BUILDING, AND PRE-CAST CONCRETE THRUST BLOCKS. 5. INSTALL (2) 2x6 STUD WITHIN EXISTING TEMPORARY WALLS TO BE CENTERED ON NEW SHEARWALLS AND THEN INSTALL NEW HORIZONTAL BLOCKING BETWEEN ALL VERTICAL STUDS AND INSTALL SHEATHING OVER THE TEMPORARY WALLS. 6. INSTALL NEW SHEARWALLS, INCLUDING TENSION STRAP & HOLDOWNS AT THE INSTALL NEW SHEARWALLS, INCLUDING TENSION STRAP & HOLDOWNS AT THE ENDS OF THE SHEARWALLS. 7. SAW-CUT THE EXISTING EXTERIOR BRICK WALLS OF 139 AT THE LOCATIONS SAW-CUT THE EXISTING EXTERIOR BRICK WALLS OF 139 AT THE LOCATIONS SHOWN ON PLAN DETAIL "1" ON SHEET S4. 8. CAREFULLY DEMOLISH & REMOVE DEBRIS OF 139 STARTING AT THE EAST END OF 139 AND WORKING TOWARDS THE WEST (143 /147). IT IS RECOMMENDED IT IS RECOMMENDED THAT ALL DEMOLITION BE CONDUCTED FROM OUTSIDE OF 139. 9. IF DEMOLITION OF 139 PROGRESSES TO THE SAW-CUTS (ITEM 7., ABOVE) WITHOUT COMPLETE COLLAPSE OF THE BRICK PARTY WALL, THEN THIS REMAINING WALL SHALL BE CAREFULLY DISASSEMBLED FROM THE TOP DOWN AND WORKING FROM THE NORTH AND SOUTH ENDS. IT SHOULD BE ASSUMED THAT THIS IT SHOULD BE ASSUMED THAT THIS REMAINING BRICK WALL COULD COLLAPSE AT ANY TIME. IT IS THE DEMOLITION IT IS THE DEMOLITION CONTRACTOR'S OPTION TO DESIGN AND INSTALL ADDITIONAL TEMPORARY SHORING OF THIS WALL TO FACILITATE IT'S SAFE DEMOLITION. 10. UPON COMPLETE DEMOLITION OF 139, THE SITE SHALL BE CLEARED OF ALL DEMOLITION DEBRIS AND 139's BASEMENT HOLE FILLED TO WITHIN 8 FEET OF 143/147's EAST WALL. 11. CONSTRUCT THE NEW EAST WALL FOR 143/147. SEE DETAIL ON SHEET S6. 12. COMPLETE THE BACKFILLING OF THE NEW 143/147 FOUNDATION WALL. 13. REMOVE THE TEMPORARY SHORING & BRACING FROM 143 /147.

BASIS OF DESIGN & LOADING CRITERIA THE BASIS OF DESIGN IS PREDICATED UPON THE ASSUMPTION THAT THE EXISTING BRICK PARTY WALL BETWEEN 139 MAIN STREET AND 143/147 MAIN STREET IS UNSTABLE AND CAN/WILL COLLAPSE AT ANYTIME AFTER DEMOLITION OF 139 IS INITIATED. SUCH A COLLAPSE WILL RESULT IN DYNAMIC LOADING TO THE REMAINING 143/147 BUILDING FROM THE FALLING BRICK. THIS LOADING INCLUDES: A. HORIZONTAL LOADS FROM THE COLLAPSING BRICK HORIZONTAL LOADS FROM THE COLLAPSING BRICK PUSHING WEST INTO THE EAST WALLS OF 143/147. . THE REINFORCING & SHEATHING OF THE EXISTING TEMPORARY WALLS AND ADDITION OF THE SHEAR WALLS ARE DESIGNED FOR THIS LOADING. B. HORIZONTAL THRUST AT THE NORTHEAST AND HORIZONTAL THRUST AT THE NORTHEAST AND SOUTHEAST CORNERS OF THE REMAINING 143/174 BUILDING. THIS IS A RESULT OF THE COLLAPSE OF . THIS IS A RESULT OF THE COLLAPSE OF BRICK AT THE LOWER LEVELS (ASSUMED TO OCCUR FIRST) CREATING "ARCHING ACTION" IN THE REMAINING BRICK WALL ABOVE AND THAT CREATES A HORIZONTAL FORCE TO THE OUTSIDE EDGES OF THE WALL. THE STRUCTURAL STEEL AND TIE-ROD BRACING ARE DESIGNED TO RESIST THESE LOADS AND PREVENT THE BRICK WALL COLLAPSE FROM PROPAGATING TO THE WEST. C. GRAVITY DEAD LOADS FROM 143/147 WEIGHT OF GRAVITY DEAD LOADS FROM 143/147 WEIGHT OF EXISTING BUILDING MATERIAL AND NEW CONSTRUCTION MATERIALS. THE REINFORCEMENT OF THE CONNECTIONS THE REINFORCEMENT OF THE CONNECTIONS OF EXISTING TEMPORARY WALLS TO EXISTING FRAMING AND THE ADDITION OF THE NEW FOOTING & 2x10 WALL IN THE BASEMENT ARE DESIGNED FOR THESE LOADS. THE FOLLOWING LOADING CRITERIA WAS USED: WEIGHT OF 8" BRICK WALL = 80 psf WEIGHT OF 12" BRICK WALL = 120 psf UNIT WEIGHT OF BRICK RUBBLE = 80 pcf "AT-REST" PRESSURE COEFFICIENT = 0.50 IMPACT FACTOR (FOR DYNAMIC LOADING) = 1.3 CONSTRUCTION LIVE LOAD = 20 psf ROOF DEAD LOAD = 11 psf ATTIC FLOOR/CEILING DEAD LOAD = 18 psf 2ND & 3RD FLOOR DEAD LOADS = 17 psf 1ST FLOOR DEAD LOAD = 8 psf 6" CMU WALL = 37 psf DEAD LOAD FACTOR = 0.60 (WHEN DEAD LEADS USED TO RESIST TENSION LOADS IN THE SHEAR WALLS)
