1. Mezzanine Update

2. Outline: Review key questions from Mezzanine Analysis presentation
Analyze Lateral Loading Scenarios
Hand rails material
Reference Material
Mezzanine Build Plan Outline

3. Next Steps/Questions:
Can the mezzanine be anchored into the supporting structure? YES
Anchors would be placed into side walls (and potential back wall) to prevent lateral movement and offer stability
If the mezzanine needs to be free standing: DOES NOT NEED TO BE FREESTANDING
Knee Braces will need to be added to each post. This requires unique analysis.
Sheathing would need to be added to the columns/post to restrict lateral movement.
Although they are not very strong, an analysis needs to be conducted on Lateral Loads to our system. IN PROGRESS
Fireproofing the structure may be a requirement from the city. PROPERTY MANAGER WAS NOT CONCERNED, ACTION TBD
A permit may be required (city originally said no, but Subject Matter Experts think one will be needed). PROPERTY MANAGER WAS NOT CONCERNED, ACTION TBD
If a permit is required, there is a chance this mezzanine analysis will need to be signed/stamped by a Professional Engineer. TBD

4. Lateral Loading Analysis
Sourced from ASCE 1.4.3
1% DL + small % LL (eng. discretion)
LL = 125 lb/ft2
LL ≈ lb
DL = 2538 lb
(0.01*2538)+(0.01*23250)
Lateral Load = 258 lb

Material
Powers Fasteners Lok-Bolt AS Sleeve Anchor
Tapcon cement screw
Angle brackets
Method
Use product data sheets to check for allowable load and shear
Attach ledger board to back wall
Secure column at top and bottom with angle bracket

6. Hand Rails Requirements Material Method
200 lb point load in any direction
OSHA height requirements
Material
1-1/2" SCH 10 (1.90 OD X .109 wall)

9. Build Plan Outline Macro Level – “Bottom Up, Back to Front” Detailed:
Measure foundation and walls to determine whether methods, such as shimming or concrete leveling, are needed to “square” facility
Lay sill plate
Cut columns (near walls only) to appropriate heights and install. Place column anchors
Place supporting beam plate along columns
Cut and install “ledger board” on back wall (anchoring to the as appropriate)

10. Build Plan Outline Detailed Continued:
Cut and install remaining beams. After (or possibly during) the placement of Beam C, begin installing columns supporting elevator opening
Install joist hangers
Cut and install joists
Place any additional anchors that may be required
Sheath the top of the mezzanine with plywood
Install handrails (and possibly stairs)
