Inspection and Design of Light Pole Foundation on Vaulted Slab

Cook County, Illinois

DB Sterlin was responsible for work that included preparation of design plans, profiles, general notes and maintenance of traffic plans for the installation of electrical conduit to proposed cellular antennas. Scope of work also included collection of data, site visits, structural design and structural analysis. Collection of data work included review of existing plans/documents, including sidewalk framing, sidewalk slab details, light pole foundation, review proposed light pole dimensions, loads, and base plate connection. Site visits consisted of obtaining authorization to access vaulted space from building owner/rep, verifying configuration and elements of existing structural systems and assess current condition of systems. Furthermore, DB Sterlin performed structural analysis of existing light pole foundation and anchor bolts to determine current structural capacity of system and developed design details of repairs and/or retrofits to existing structural system to accommodate installation of new light pole.

The project consisted of the installation of mini macro antennas onto new light poles throughout the City of Chicago. The mini antennas provide additional cellular signal in low coverage areas. DB Sterlin was responsible for verifying electrical power source availability, pavement conditions and evaluating presence of potential conflicts (vaulted sidewalks, other utilities, etc.).
