835.3Construction.
A.Construct cabinet base in accordance with the contract.
1.When excavating the area for the cabinet base, do not exceed the dimension of the base
foundation by more than 12 -inches in any direction.
2.When placing a base in existing concrete pavement or sidewalk, saw cut the concrete in a
square pattern or remove the concrete to the nearest joint.
3.Stockpile excavated material on the site until completion of backfilling.
4.Place the cabinet base stone to a depth of 6 -inches or as directed by the engineer.
5.Excavate additional space for the required concrete apron and place stone in the extended area
when placing the base in an unpaved area.
6.Set the ground rod as shown in accordance with the Standard Construction Details and in
accordance with Section 833. Drive the ground rod a minimum of 8 feet into soil through a 2 -inch PVC sleeve.
B.Set conduit sweeps as shown in the contract.
1.Drive the PVC sleeve for the ground rod into the ground so that the top of the sleeve is 2 -inches
above the base concrete when poured.
2.Place forms to the full depth for the base and install conduit sweeps in accordance with the
Standard Construction Details .
3.Use conduit 90 -degree sweeps with elbows having a 24 -inch radius.
4.Leave a minimum of 2-inches and a maximum of 4-inches of conduit exposed above finished pad
grade.
5.Connect conduit sweeps to the existing conduit in accordance with the contract. Cap unused
conduit sweeps with tape. Mark the direction of the conduit run the sweep is connected to on the base with arrows drawn in the wet concrete within 6 -inches of outer edge of the base. CABINET BASES SECTION 835

836.3Construction.
836.3.1 Installation.
A.Notify the engineer 2 working days in advance to obtain the materials from the Department. Pick
up the materials at the DelDOT Sign Shop.
B.Assemble steel poles and mast arms. Before erecting a pole, ensure that the anchor bolt is
revealed per the manufacturer’s specifications and Standard Construction Details. Notify the engineer if the existing anchor bolts do not meet this criteria and wait for instructions. Do not erect the pole until directed.
C.Identify aerial utilities within the area and coordinate the work with the owner of the utility.
Install poles at least 10 -feet below or 10 -feet away from primary electric cables.
D.Remove conduit caps or knockouts from the conduit that extend from the pole base.
E.Install insulated grounding bushings.
1.Install a #6 AWG copper ground wire between the 3/4 -inch ground rod clamp and the insulated
grounding bushing and attach to the lug or stud in the metal pole or pedestal.
2.Continue the #6 AWG copper ground wire, on multi -section steel camera poles, to the top of the
upper section of the pole from the insulated grounding bushing to a bonding lug attached to the camera mounting bolts.
3.Do not install or temporarily place the #6 AWG copper ground wire between the leveling nut
and the pole.
F.Raise steel pole or pedestal pole into position.
1.Place pole on the anchor bolts. Hold the pole in place until completing installation and
tightening of the anchor bolt the nuts.
2.Use a nut under the base of the pole and a nut above the base of the pole on all steel pole
