South Florida Water Management District G-716

The G-716 spillway is within the STA-1E Inflow Distribution Area, along the levee between the East Distribution Cell (EDC) and the West Distribution Cell (WDC). WGI’s Specialty Structures Division designed, detailed, and provided construction phase services to South Florida Water Management District (SFWMD) for a fully automated, electronically operated, three (12 foot by 16 foot) gated spillway to increase the capacity of flow between the EDC and WDC to 3600 cfs. WGI prepared construction documents and performed construction management for a reinforced cast-in-place concrete spillway with steel sheet piles wingwalls, seepage cutoff walls, concrete weir structure, embedments for automated roller gates, needle-beam supports for temporary dewatering panels, concrete guide towers for roller gates with raised control platform, prestressed concrete access bridge, precast concrete control building, and stilling well platforms. During construction, WGI provided on-site representatives to examine critical design components; review and assist SFWMD in responding to shop drawing submittals, requests for information, change orders, field orders, value engineering, and submittals; review of testing results; and provided record drawings based on contractor certified as built information and completion certification.
