HIGHMAST LIGHTING NOTES:
DESIGN CRITERIA:
1.
1.
Designed in accordance with the FDOT Structures Manual.
2.
Poles are designed to support the following:
High Mast materials:
a. Pole: ASTM A1011 Grade 50, 55, 60 or 65 (Less than …") or ASTM A572 Grade 50,
55, 60, or 65 (…" and over) or ASTM A595 Grade A (55 ksi yield) or Grade B (60
ksi yield).
a.
(1) cylindrical head assembly with a maximum effective projected
b.
(8) cylindrical luminaires with a maximum effective projected area
area of 6 SF (Cd=1) and 340 lbs (Max).
b. Steel Plates: ASTM A709 Grade 36 or ASTM A36
of 3.0 SF (Cd=0.5) and 77 lbs. each.
c. Weld Metal: E70XX
3.
d. Anchor Bolts: ASTM F1554 Grade 55 with ASTM A563, Grade A heavy-hex nuts and
plate washer.
Foundation design based upon the following soil criteria:
Classification
= Cohesionless (Fine Sand)
Friction Angle
= 30 Degrees (30)
Unit Weight
=
50 pcf (assumed saturated)
e. Handhole: ASTM A709 Grade 36 or ASTM A36 Frame with ASTM A36 cover.
Only in cases where the Designer considers the soil types at the
f. Caps: ASTM A1011 Grade 50, 55, 60 or 65 or ASTM B209.
specific site location to be of lesser strength properties should an
analysis be required. Auger borings, SPT borings or CPT soundings may
g. Nut Covers: ASTM B26 (319-F)
be utilized as needed to verify the assumed soil properties, and at
relatively uniform sites, a single boring or sounding may cover several
h.
Stainless Steel Screws:AISI Type 316
foundations. Furthermore, borings in the area that were performed for
other purposes may be used to confirm the assumed soil properties.
2.
Reinforcing steel: ASTM A615, Grade 60.
3.
Concrete: Class IV (Drilled Shaft) with a minimum 4,000 psi compressive strength at
4.
Foundation applies only to slopes of 1:4 or flatter. Provide a minimum
5.
Poles are designed for 6 mil galvanization thickness.
24" shaft projection on the high side.
28 days for all environmental classifications.
4.
Welding: American Welding Society Structural Welding Code (Steel)
ANSI/AWS DI.1
Current edition).
5.
Galvanization:
a. Nuts, Bolts, Washers and Threaded Bars/Studs: ASTM F2329.
b. Other items (Including Pole): ASTM A123
6.
Hole diameters for anchor bolts: not greater than the bolt diameter plus ‰".
7.
Poles: Tapered with the diameter changing at a rate of 0.14 inch per foot with a
minimum 16-sided pole shaft and maximum of two longitudinal seam welds. Circumferentially
welded pole shaft butt splices and laminated pole shafts are not permitted.
Longitudinal seam welds within 6 inches of pole to base must be complete penetration
welds. Longitudinal seam welds at telescopic field joints must be complete penetration
welds for the splice length plus 6 inches.
C:
\d\projects\standards\roadway\17500-s\17502-01.
dgn
8.
One hundred percent of full-penetration groove welds and a random 25 percent of
partial penetration groove welds shall be inspected. Full-penetration groove weld
inspection shall be performed by nondestructive methods of radiography or
ultrasonics.
9.
Furnish each pole with a 2"x4" (Max.) aluminum identification tag. Submit details for
approval. Secure to pole with 0.124" stainless steel rivets or screws. Locate
identification tag on the inside of pole and visible from handhole. Include the
following information: Financial Project ID, Pole Mounting Height, Manufacturer’s Name, Fy of
Steel, and Base Wall Thickness.
10. Verify CSL access tubes will not interfere with anchor bolt installation before
excavating the shaft. When CSL access tube locations conflict with anchor bolt
locations, move the CSL access tube location – two inches along the inner
circumference of the reinforcing cage. Notify the Engineer before excavating the
shaft if the CSL access tube locations cannot be moved out of conflict with anchor bolt
