GENERAL NOTES:
I. Chang Ahn, PE, is the Project Engineer of The Record. Any
structural engineering issues shad be directed to This Engineer.
2. Building Codes: All construction work performed for this project shall
comply with the 2018 IRC.
3. CONTRACTOR'S APPROVAL:
a. Contractor shall, prior to starting construction, coordinate all the
construction documents of the latest revision, verify all the dimensions,
check for conflicting requirements and report to This Engineer any
discrepancies and field conditions which are different from those
indicated on drawings.
b. Areas requiring special attention: variation caused by different
architectural elevations, e.g. location changes of holdowns and post
anchors due to different window sizes, location and porch layout, the
existence or nonexistence of interior bearing wall and footings,
planter shelves, box columns, brick ledge, isolated column pads in
3-Gar Garage option, etc.
4. STRUCTURAL ONLY:
a. Structural drawings are intended to cover the structural framing and
the foundation elements only. Non-structural elements including
decorative architectural elements, stair framing, guard rails, concrete
pads, driveway, etc. may not be covered in the structural drawings.
Contractors are advised to review all other plans and construction
documents for non-structural items which may be embedded in, attached
to or otherwise interfering the structural elements.
b. MARBLE/TILE: Where marble/tiles are installed, it is the contractor's
responsibility to consult with an expert for special framing advice to
avoid cracking which may include ups izIng the floor joists, reducing the
joist span $ spacing, increase the thickness of floor sheathing, etc.
c. Lee Engineers is not responsible for the ventilation, including under -floor,
joist and attic, nor concrete flat work including concrete driveway,
walkway, door pads and other similar items. Images and/or dimensions
the flat work are intended to be conceptual. Contractors shall follow
given for the Architectural Plans or Owner's specifications for final
location, geometry and dimensions.
5. NOT TO SCALE: Drawings are not to be scaled. Dimensions not specified,
when required by field condition, shall be determined by Engineer.
(b. TYPICAL DETAILS: Typical and similar details shall apply where no specific
details are given. Material notes and details on drawings shall take
precedence over the structural notes contained herein.
7. REVISIONS 4 MODIFICATIONS:
a. All drawings and subsequent revisions, if any, shall be approved prior
to starting construction. No structural members shall be substituted,
relocated or omitted, without prior written approval.
b. Field Modifications: When the installation of mechanical, plumbing,
electrical, landscaping and other similar elements requires changes or
modifications including boring, notching, or cutting made to the
structural elements, contractor shall submit such changes or
modification to Lee Engineers for approval prior to installation.
c. NOTCHING of Beams, Joists, and Rafters: Notching from the top edge or
the bottom edge is never permitted without approval. Boring is allowed
only if located within the middle 1/5 span and the hole size shall be
limited to 1/6 of member depth.
8. ADDITIONAL EQUIPMENT: Unless specified on the structural framing plans,
mechanical and plumbing equipments, e.g. spa tub, FAU, etc., to be placed
over or suspended off the structure members shall be submitted to This
Engineer for approval.
cl. CONSTRUCTION SAFETY: Contractor and the subcontractors are
responsible for the order and means of construction and all temporary
bracing 4 erection during construction.
10. 5heetrock Stacking Guidelines: When 5heetrock is stacked on a wood -framed
floor during construction, the following guidelines shall be followed:
a. The sheetrock shall be laid with the LONG DIRECTION PERPENDICULAR to
the joists below.
b. 5heetrock must not be stacked more than 2 feet high.
c. If sleepers are used beneath a stack of sheetrock, they shall be
placed at no more than 2'-O" o.c.
d. The floor joists directly beneath a stack of sheetrock shall be shored
from below with 4x4 temporary beams placed PERPENDICULAR to the joists.
These beams shall then be supported by min 2x4 posts over 4x4x24"
sleepers at a maximum spacing of 3'-0" o.c.
This shoring shall be done prior to stacking the sheetrock and shall
be repeated on every floor directly below the stacked sheetrock until
a concrete slab or foundation system is reached.
e. If contractor prefers not to provide shoring for the stacked sheetrock
as specified above, the maximum height of sheetrock allowed to be
placed on the floor is a inches.
FOUNDATION NOTES:
I. SOILS REPORT: Boils Report is not available for this project.
2. GRADING $ DRAINAGE:
a. Site grading, subgrode preparation, cutting slopes, excavation and
placement of engineered fill material shall be performed in accordance
with the Soils Report.
b. For slab -on -Grade construction the soils Report shall be referenced
regarding compaction, soaking, moisture barrier, sub -base, gravel,
sand, etc.
c. Site drainage requirements including final pad grades, roof drainage
downspouts shall be referred to Soils Report and Architectural Plans.
d. FINISH GRADING: Finish grading around the exterior of the foundation
shall be sloped to drain away from the building and be a minimum of 8"
below the sill plate. Contractor must follow the soils report for
grading details.
3. CONCRETE:
a. Concrete for foundations shall have a minimum compressive strength of
b. Owner/Builder shall consult with a geotechnical engineer to determine if
the underlying soil contains sulfate or if the building site is exposed
to salt Hater. If sulfate and/or salt water exposure exist, A1 515-05
shall be followed in concrete mix design.
c. Cold joints may be used only where shown. Jointing surface shall be clean,
free of foreign material and intentionally roughened.
4. REBAR:
a. Unless specified otherwise, reinforcing steel shall be deformed bars
of billet or axle steel per A5TM A615 Oracle 40. For #5 and bigger
Oracle 60 shall be used.
b. Reinforcing bars to be welded shall be A57M A706.
c. INSTALLATION: Rebor, dowels and other embedded elements shall be
secured in place before pouring concrete. Reinforcement shall be clean
and free of extraneous material.
cl. CLEARANCE:
* 3" clearance shall be provided where concrete is cast against earth,
* 2" clearance for concrete exposed to earth or weather but deposited
against forms, and
* 3/4" clearance for slabs and walls where concrete is not exposed to
earth or weather.
e. LAPPING: Lap all reinforcing splices a minimum 48 bar diameters but in
no cases less than 24".
