803.03 Equipment — Vacant
803.04 Construction Methods
Provide underground enclosures as shown on the Plans. Obtain the Resident Engineer’s approval to revise enclosure locations to fit field conditions or facilitate conduit system installation. Use pull boxes to distribute electrical service. Provide ground boxes for communication applications, such as Intelligent Transportation Systems.
A.Installation Install underground enclosures on a bed of crushed rock as shown on the Plans. For underground enclosures installed in surfaced areas, make the top of the enclosure flush with the finished surface. For underground enclosures located near curbs as required by the Contract, place adjacent to the back of the curb and flush with the top of the curb. For underground enclosures in ground, ensure the top of the enclosure is flush with the top of, or no greater than 1 in [25 mm] above, the ground surface. Unless otherwise approved by the Resident Engineer, provide underground enclosures wit h concrete aprons, at no additional cost to the Department. Install conduits entering underground enclosures as shown in the Plans and in accordance with Section 802, “Electrical Conduit.” Provide underground enclosure extensions of the same material as the enclosure if shown on the Plans. Attach extensions to the underground enclosure to maintain the depth shown on the Plans without causing assembly separation.

804.04 Construction Methods
A.Footings Construct level concrete footings on firm ground in accordance with Section 509, “Structural Concrete” to minimize shimming. Construct footings at the locations shown on the Plans and to the grade directed by the Resident Engineer. If an obstruction prevents the construction at the planned location, construct footings at the location directed by the Resident Engineer. Erect the pole, post or breakaway base after the foundation reaches 100 percent of the required 28 day compressive strength and ages at least 72 hr. The Resident Engineer may waive this restriction if the pole, post, or breakaway base is set directly in the footing. Modify footings shown on the Plans based on fiel d conditions and with the approval of the Resident Engineer. After completing the footing, restore the surrounding area as approved by the Resident Engineer.
B.Anchor Bolts Use anchor bolts of the size and quantity shown on the Plans. Use a template to l ocate and secure anchor bolts in the footing. Provide anchor bolts with the top exposed portion plus 6 in [150 mm] galvanized and threaded as shown on the Plans. Supply the anchor bolts with galvanized hex head nuts, flat washers, and lock washers as sho wn on the Plans. Do not weld any part of the anchor bolt.
