Poles set on concrete foundations shall not be installed until a minimum 70% of the 28-day concrete compressive strength has been achieved. A minimum of two successful cylinder tests must be performed to verify minimum required strength and test results must be accepted by the Engineer. For poles installed on concrete foundations, the following procedure for installing nuts shall be followed:

1.Verify that the nuts can be turned onto the bolts past the elevation corresponding to the bottom of each in-place leveling nut and be backed off by the effort of one person on a 12-inch long wrench or equivalent, without employing a pipe extension on the wrench handle.

2.Clean and lubricate the exposed threads of all anchor bolts. Clean and lubricate the threads and bearing surfaces of all leveli ng nuts. Re-lubricate the exposed threads of the anchor bolts and the threads of the leveling nuts if more than 24 hours has elapsed since earlier lubrication, or if the anchor bolts and leveling nuts have become wet since they were first lubricated.

3.Turn the leveling nuts onto the anchor bolts and align the nuts to the same elevation.

4.Place structural plate washers on top of th e leveling nuts; one washer corresponding to each anchor bolt.

5.Install the base plate onto the leveling nut washers, place structural plate washers on top of the base plate; one (1) washer corresponding to each anchor bolt, and turn the top nuts onto the anchor bolts.

6.Tighten top nuts to a “snug-tight” condition in a star pattern. Snug-tight is defined as the maximum nut rotation resulting from the full effort of one person on a 12-inch long wrench or equivalent. A star tightening pattern is one in which the nuts on opposite or near opposite sides of the bolt circle are successively tightened in a pattern resembling a star.

7.Tighten leveling nuts to a “snug-tight” condition in a star pattern. The distance from the bottom of the leveling nuts to the top of the concre te must not exceed one (1) anchor bolt diameter.

8.Before final tightening of the top nuts, ma rk the reference position of each tip nut in a snug-tight condition with a suitable marking on one flat with a corresponding reference mark on the base plate at each bolt. Then incrementally turn the top nuts using a star pattern until achieving the required nut rotation specified in the following table. Turn the nuts in at leas t two (2) full tightening cycles (passes). After tightening, verify the nut rotation. Do not exceed the value specified in the following table by more than 20 degrees. Anchor Bolt Diameter (inch) Nut Rotation from Snug-Tight Condition Less than or equal to 1.5 inches 1/3 Turn Greater than 15 inches 1/6 Turn

9.Tighten each retainer or jam nut until it is in firm contact with the top surface of the anchor bolt nut then while preventing the anchor bolt nut from rotating, tighten the jam nut unit it is snug tight. After alignment of pole on the concrete foundation is completed and accepted by the Engineer, the entire area between the bottom of the pole base flange and the top of the concrete foundation shall be protected, using an acceptable method, to prevent foreign objects from entering the described area. Careful aligning of the poles shall be considered a most essential feature of the installation of th e assembly and shall be as nearly perfect as practicable.
