Design Criteria
Design Criteria See Instructions for Index 521-510 and/or Index 521-511.
Design Assumptions and Limitations
Design Assumptions and Limitations Use this Standard with Index 521-510 and/or 521-511 when the Concrete Barrier / Noise Wall (8'-0") and/or (14'-0") is installed on an L-Shaped spread footing. Footing stem wall may be widened at no additional cost, to accommodate slip forming. Project specific details are required for the use of 10'-0" and 12'-0" tall Concrete Barrier / Noise Walls.
