Project: McMahon Decks
Project Address: 831 Main Street
During review of the plans for the above noted project, it was found that the following information,
clarifications or changes are needed. Please provide written responses as to where the changes can
be found on the plans, and submit revised plans/documents to a Permit Coordinator.
1.Provide gravity engineering calculations for the following:
a.The roof converted to a deck. Roof loads are less than deck loads and we need to be
sure that the existing structure will support the additional floor loads.
b.Beam calculations. The proposed 4x12 beam is severely undersized
c.Joists sized for the 5 cantilever. The proposed 2x8s do not meet the prescriptive
requirements.
d.Column and footing design.
2.Lateral engineering calculations:
a.Nailing Schedule for replacement plywood.
b.Lateral requirements for deck
c.Ledger connection details.
3.Guard, handrail and tempered glass:
a.Provide details showing materials and connections
b.Justify the code load requirements:
i.200 lb at any location on the top rail of the guard, or along the handrail
ii.50 psf at the body of the guard (the tempered glass). If there is the product
literature available, it may be satisfactory to provide this information.
4.Stairs:
a.Call out rise, run, and nosing.
b.Identify stair stringer materials.
c.Show what materials are used for construction.
d.Identify landing materials at top, intermediate, and bottom landings.
e.Indicate on plans the light nearest the top landing to see if will comply with R303.6,
stairway illumination.
5.Identify existing deck materials that are proposed to remain- Joists, beams,posts, and footings.
Call out if pressure preservative treated or not. If not PT or wood naturally resistant to decay,
they will need to be replaced.
6.Not all hangers that are in contact with PT wood have been identified as hot dipped galvanized
or stainless steel. Provide a note that all fasteners and hardware in contact with PT wood to be
hot dipped galvanized or stainless steel, with the exception of ½ and larger bolts.
