Junction Box Frames and Lid Sets

The City of Pittsburgh, through its Office of Management & Budget on behalf of the Department of Mobility & Infrastructure, is seeking quotes for junction box frames and lid sets. These components are essential for traffic signal infrastructure. The specifications detail requirements for the JB-1 City Standard junction box, including materials such as Class AA Cement Concrete, reinforcement bars, and specific aggregate types for backfill and stone drains. The hatch cover frame and hatch cover support must be made of 6061-T6 aluminum. Junction box lids are to match adjacent sidewalk materials in finish and color, with a penetrating concrete sealer for the concrete lid. Construction requirements include precise installation, backfilling with compacted aggregate, and setting the lid elevation flush with adjacent ground to prevent tripping hazards. Temporary lids must be sturdy, and shop drawings require electronic submission for approval by the Municipal Traffic Engineer.
