The curved canopy tops were covered with standing seam metal roofing and the sides were covered with phenolic wall panels manufactured by Trespa in the Netherlands to provide a finished look matching the adjacent Southbay Expressway operations building.

General

• Provided engineering survey, steel fabrication, shop drawings, and installation of batter boards and sono tube forms for the drilling and placement of the reinforced concrete caissons.
  
  
• Provided the material and constructed the metal stud framing for the phenolic panel siding.
  
  
• Prepared structural shop drawings for underground concrete caissons, steel rebar cages, steel structures, stud frames for supporting Phenolic siding panels, and standing seam metal roofing.
  
  
• Coordinated with other contractors and Otay River Constructors.
