Some sample guidelines for
structural plans followed by Peyman Group
CONCRETE AND MASONRY STRUCTURES
Use a minimum concrete ultimate compressive
strength of 3000 psi at 28 days.
Specify size of aggregate and slump. Use
1-inch or ¾-inch minimum aggregate size, with
smaller sizes only in very special cases.
Avoid thin sections or projections that may
crack off when forms are removed. Chamfer column
corners, exposed corners and edges.
Provide typical construction joint locations
for concrete beams, joists and slabs.
Provide expansion joints, control joints and
seismic-movement joints as required by the
design, indicate their locations and details on
drawings and coordinate with architectural
enclosures and finishes.
Joints must be weather tight and provide
lateral stability across the joint.
Where a concrete beam is monolithic with a
concrete wall and negative beam reinforcing
steel is embedded in the wall, include a detail
that shows the preferred pour line and alerts
the contractor not to pour wall without negative
reinforcing in place.
depressions and curbs on structural floor and
Maintain a full depth of slab under
depressions for ceramic tile, electric ducts or
Provide a typical column drawing indicating
bar maximum slopes, locations of splices and reglets for shear-wall reinforcing.
When setting a rail post use non-shrink grout
or equivalent (“Por-Rok” but not sulfur).
Provide a #4 bar on each side of post in
If wood or steel studs are used in concrete
buildings, indicate clear relationship between
“face of concrete” and “face of studs”.
In masonry walls, base dimensions on modular
size of the unit.
In concrete masonry walls, fill all cells
except on free-standing site walls retaining no
earth. Avoid bars larger than Number 8.
Clearly show the minimum
concrete cover required for the intended fire
Provide top-of-steel elevations at each column
and change of level on structural
drawings for ease of reference by steel
detailers and erectors.
For exterior steel work specify sections with
a thickness of ¼” or greater.
Indicate required camber on all tapered steel
girders and steel trusses.
Keep steel floor beams to L/D equal to or less
Provide erection bracing
for tapered girders. Web thickness for
all built-up sections shall be at least
3/16". Provide flange to web welds to
comply with AISC specification. Use
stiffener plate welded to top flange and
to web where ridge occurs.
Comply with maximum width-to-thickness ratio
requirements of AISC for projecting elements
under compression. Apply requirements to railing
Field weld or use cadmium plated counter-sunk
flat head machine screws, to prevent warping in
Specify cost effective size, length and type
of welds. Use standard weld symbols and consider
fillet welds where adequate.
Make groove welds "full penetration" on
structural welds such as tapered girder flanges.
On welded assemblies to
be hot-dip galvanized, avoid shop
welding large areas, such as stair
platforms, to prevent warping in
galvanizing bath. Field weld and retouch
galvanizing, or use cadmium plated
counter-sunk flat head machine screws
for field assembly.
Provide means of leveling for base plates,
such as double nuts on anchor bolts.
No horizontal member depth to thickness ratio
shall exceed 7.
Bottoms of sills on exterior foundation walls
shall be not less than 12" above finished grade.
Design hold downs and
Provide special framing
elevations where large openings occur,
where columns pass through wall plates,
or where framing is otherwise complex.
Provide complete roof
framing plans showing walls. Clearly
indicate corner framing and slope of
Use nominal 6" wide
studs for walls with the exception of
non-bearing walls with no piping.
connection of vertical shear elements to
diaphragms. Be sure these shear elements
do not produce a high concentration of
stress over a small length.
Use minimum 1/2" thick
plywood for roof sheathing. Indicate
stagger of panels required for
