852.04 Overh Ead Sign Structures
SECTION 852 OVERHEAD SIGN STRUCTURES
852.01 Description
This work consists of providing and constructing overhead sign structures on prepared footings.
852.02 Materials
Provide materials for overhead sign structures in accordance with Section 720, “Overhead Sign Structures.” Provide materials for concrete footings in accordance with Section 804, “Concrete Footings.” Provide drilled shaft footings in accordance with Section 516, “Drilled Shaft Foundations.” CSL tubes will n ot be required.
852.03 Equipment — Vacant
852.04 Construction Methods
A.Design Use general data in accordance with the AASHTO Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals to design overhead sign structures. Submit shop drawings to the Resident Engineer for approval before construction.
B.Welding Qualify procedures, welders, and welding in accordance with Subsection 720.03, “Welding Requirement,” and AASHTO/ANSI/AWS D 1.1.
C.Fabrication Provide overhead sign structures free of sharp edges, irregularities, misfits, or structural deficiencies, as approved by the Resident Engineer. Complete overhead sign structures as shown on the Plans. Ensure that all anchor bolts, base plate s, and flange plates are properly aligned to prevent unacceptable distortion of the structure upon final installation. In the event that the drilled shaft and anchor bolts are installed before the fabrication of the structure, coordinate with the fabricat or to ensure that the base plates and flanges are fabricated so that proper alignment of all bolt holes is achieved. In the event that the structure is fabricated before the installation of the drilled shaft and anchor bolts, coordinate with the structure fabricator to ensure that the anchor bolt installation allows for proper alignment of all bolted connections.
