Gt. SCOPE
THE NOTES ON THIS SHEET AND THE STANDARD STRUCTURAL DETAILS ARE GENERAL AND
APPLY TO THE ENTIRE PROJECT WHETHER SPECIFICALLY CALLED OUT OR NOT, EXCEPT
WHERE THERE ME SPECIFIC INDICATIONS TO THE CONTRARY ON STRUCTURAL SHEETS. IF
THERE ARE QUESTIONS, THEY SHALL BE SUBMITTED TO THE STRUCTURAL ENGINEER AND
ANSWERED IN WRING PRIOR TO CONSTRUCTION.
G2. APPLICABLE SPECIFICATIONS ANO CODES
A. IBC 2012 WITH APPUCABLE EDITIONS OF THE CODE REFERENCED STANDARDS.
B. LOCAL JURISDICTION AMENDMENTS
G3. DESIGN CRITERIA
1. APPLIES TO ALL STRUCTURES (UNO)

I. BASIC SEISMIC FORCE RESISTING SYSTEM:
j. SEISMIC RESPONSE COEFFICIENT. = 0.57
G4. ;;AF
SAFETY AND STRUCTURE STABIUTY DURING CONSTRUCTION ARE THE SOLE RESPONSIBILITY
OF THE CONTRACTOR. STRUCTURES HAVE BEEN DESIGNED TO RESIST THE DESIGN LIVE
LOADS ONLY AS A COMPLETED STRUCTURE.
G5. OPENINGS
OPENINGS FOR PIPES, DUCTS, CONDUITS, ETC. ARE NOT ALL SHOWN ON THE
STRUCTURAL DRAWINGS. COORDINATE AND PROVIDE OPENINGS AS REQUIRED TO
ACCOMMODATE ALL WORK SHOWN OR SPECIFIED IN THE CONTRACT DOCUMENTS AND
OTHERWISE REQUIRED FOR THE FURNISHING OF A FUNCTIONALLY COMPLETE PROJECT.
REINFORCE AROUND OPENINGS PER STANDARD STRUCTURAL DUALS UNLESS OTHERWISE
SHOWN.
06. SPECIAL INSPECTIONS
SPECIAL INSPECTIONS ME REQUIRED IN ACCORDANCE WITH CHAPTER 1 AND CHANTER 17
OF THE IBC. PAYMENT FOR THESE INSPECTIONS IS NOT THE RESPONSIBILTIY OF THE
CONTRACTOR. THE CONTRACTOR SHALL PROVIDE FOR FULL ACCESS TO THE WORK BY
THE SPECIAL INSPECTOR AND SHALL PROVIDE FOR THESE INSPECTIONS IN HIS
CONSTRUCTION SCHEDULE IN ACCORDANCE WITH THE SPECIFICATIONS.
G]. STANDARD DUALS
THE STANDARD DUALS DEPICT TYPICAL DETAILING TO BE USED ON THIS PROJECT. IF
CONDITIONS ME NOT EXPLICITLY SHOWN ON THE DRAWINGS THEY SHAT BE MADE
SIMILAR TO THE STANDARD DETAILS. OBTAN APPROVAL OF ENGINEER IN WRITING FOR
SIMILAR CONDITIONS PRIOR TO CONSTRUCTION.
GB. THE CONTACTOR SHAT FIELD VERIFY AL DIMENSIONS AND ELEVATIONS OF EXISTING
CONSTRUCTION AS REQUIRED TO COORDINATE NEW CONSTRUCTION. SUBMIT REQUIRED
CHANGES FOR APPROVAL.
G9. CONTRACTOR TO SUBMIT FOR REVIEW ALL EQUIPMENT SIZES, OPERATING WEIGHTS,
VIBRATION FORCES. SUPPORT LOCATIONS. ALONG WITH ANY FLOOR OPENINGS. NOTCHES.
AND RECESSES REQUIRED BY SUCH EQUIPMENT. CONCRETE SUPPORT PADS AND/OR
FRAMING REQUIRED TO SUPPORT SAID EQUIPMENT SHAT NOT BE FABRICATED AND
PLACED UNTIL THE CONCRETE SUPPORT PADS AND/OR FRAMING IS APPROVED TO
SUPPORT THE EQUIPMENT.
S1. DESIGN STRENGTHS:
WIDE FLANGE AND TEES: Fy=50 KSI
PIPES: Fy=35 KSI
STAINLESS STEEL Fy=33 KSI
HSS SECTIONS Fy=46 KSI
ALL OTHER PLATES AND SHARES: Fy=36 KSI
S2. DIMENSIONS:
TO CENTERLINES OF COLUMNS AND BEAMS, TOP SURFACES OF BEAMS AND TUBES AND
HACKS OF CHANNELS AND ANGLES UNO.
S3. ELEVATIONS:
TOP OF STEEL REFERS TO TOP SURFACE OF MEMBER OR FLANGE UNO.
S4. WHEN FILLET WELD SIZE IS NOT INDICATED, PROVIDE MAXIMUM WELD SIZE BASED ON
MATERIAL THICKNESS IN ACCORDANCE WITH AISC SPECIFICATIONS.
S5. ALL BOLTED STRUCTURAL CONNECTIONS ARE BEARING TYPE CONNECTIONS UNLESS
OTHERWISE SPECIFIED TO BE SLIP—CRITICAL. PROMDE LOAD INDICATING WASHERS AT
SUP—CRITICAL CONNECTIONS.
S6. CONFORM TO AISC 360, STEEL CONSTRUCTION MANUAL AND AISC 341. SEISMIC DESIGN
MANUAL.
S]. THE SEISMIC LOAD RESISTING SYSTEM (SLRS) IS DENOTED ON THE FRAMING PLANS AND
FRAME ELEVATIONS. THE SLRS DESIGNATION INCLUDES THE MEMBER AND CONNECTIONS
AT EACH END. FRAMES ARE DENOTED AS FOLLOWS:
A MOMENT FRAME: (SLRS)
B. CONCENTRICALLY BRACED FRAME: (SLRS)
FOR SLRS SYSTEMS OR PARTS OF SYSTEMS THAT ARE NOT INCLUDED IN FRAMES,
(SLRS) IS PLACED NEXT TO THE BEAM SIZE ON THE FRAMING PLAN (eg: ON A
COLLECTOR ELEMENT (DRAG STRUT):MEMBER DESIGNATION (SLRS)
SB. ALL STEEL BEAMS SHALL RECEIVE STANDARD CAMBER PER THE SPECIFICATIONS UNLESS
NOTED OTHERWISE ON THE PLANS. BEAMS REQUIRING SPECIAL CAMBER ME DENOTED
ON THE BEAMS SHOWN ON THE FRAMING PLANS. EXAMPLE: (+1/27 INDICATES X".
