A. Conduct a field verification of the existing illumination levels and deliver a report with the results to both the owner and the Engineer of Record (EOR). Existing illumination levels must be maintained during construction by providing temporary lighting as necessary. B. Conduct a survey to verify the grade elevation at each high mast location. C. Remove the existing high-mast lighting fixtures, collision avoidance lights, lowering devices, wiring harnesses, all electrical equipment inside the pole bases, lowering systems as well as the control panels and wiring connections on the exterior of the pole bases. D. Temporarily remove the High Mast to allow for retrofit work. Laydown areas for the poles in the cargo yard will vary based on location and will be determined by Seaboard/POMTOC. In some cases, the laydown area may be adjacent to the base, while in others, it may be within the yard. The contractor is responsible for moving the poles to these designated areas to perform the work. The contractor shall confirm the location of each pole laydown area prior to commencing the retrofit. E. Preserve the existing circuits and wiring from the underground handholes to each pole for connection to the new control panels. F. Repair the existing concrete base in compliance with the structural drawings and address the defective bollard installations to ensure they meet the required standards and functionality. G. Install the new equipment, including lights, wiring, control panels, and mounting brackets, as indicated in the plans. H. Provide a structural system to support the control panels at each high mast location. I. Upon completion of the installation, the contractor shall conduct a photometric study of the new cargo yard lighting and provide a signed and sealed photometric report reflecting the study results.
