Deck Construction
1. Place shoring as shown in the certified prints. If using the optional Fairbanks
corrugate and shoring kit:
-- Shoring is pre-cut and primed L 2” x 2 3 /
16
” formed steel angle.
-- 11’ and 12’ scales each use 5 pieces of shoring per bay.
14’ scales use 6 pieces of shoring per bay.
-- Space shoring evenly in the bay starting 6 to 8” from main beam.
-- Maximum spacing for shoring is 3’0”.
-- Place each piece of shoring so that the extended flat edge is resting on top
of the cross beams’ bottom flange.
2. Cut the corrugated sheeting to fit between the main beams.
If using the optional Fairbanks corrugate and shoring kit:
-- Corrugate is precut in two sizes: 7’ x 2’6” and 3’6” x 2’6”.
-- Minimum sheeting thickness must be 24 gauge.
-- 11’ and 12’ wide scales use 4 pieces of the 7’ corrugate per bay. 14’ scales
use 4 pieces of 7’ corrugate, plus 2 pieces of 3’6” per bay.
-- Lay the corrugated steel sheeting between the crossbeams, on top of the
bottom flange and shoring bars.
-- Overlap at the seams at least one full pitch.
-- Ribs should run in the cross-traffic direction (along scale width). See Figure 2-6.
3. Install the deck rebar according to the certified setting plan supplied by
Fairbanks Scales. If using the optional Fairbanks rebar kit:
-- Rebar comes in 4’6” x 4’2” preassembled mats. These mats are not the
same as typical Welded Wire Fabric. They use heavy duty deformed bars
rather than thin wires.
-- 11’ and 12’ wide scales require 3 rebar mats per bay.
14’ wide scales require 4 rebar mats per bay.
-- Lay rebar mats on top the anchor studs that extend from the crossbeams.
-- Narrowly-spaced bars in mat (4” on center) should run across the width of the
scale. Bars with wider spacing (8” on center) should run in the direction of traffic.
See Figures 2-7 and 2-8.
4. Pour bays sequentially from one end to the other. Do not skip bays.
5. Hand trowel or broom to desired finish.
6. Allow deck to moist cure for seven (7) days, or coat with liquid curing compound
instead.
 Do not use or calibrate scale until the deck has cured and reached 4000psi
minimum compressive strength.
