Project Highlights

 
Oakland Park - Pompano 138kV - FPL

Existing wood pole structures replacement with new round spun concrete poles scope included developing PLS CADD Project model, selecting new route/poles locations, developing permit and construction drawings, cost estimates, construction packages, and ordering poles and materials.

Oakland Park - Sistrunk #2 138kV - FPL

Project initially started as a hardening project consisting of replacing existing wood pole structures with new round spun concrete poles. Due to the inaccessibility for construction and maintenance of existing wood structures to be replaced, it was decided to relocate the portion of line on existing road right of way with a portion of the line sharing an existing distribution easement. Project scope included developing PLS CADD model, selecting new route/poles locations, developing permit and construction drawings, cost estimates, construction packages, and ordering poles and materials.

Project consisted of the replacement of Three wood pole structures including two wood H-Frames structures inside FPL Lauderdale Plant right of way. Project scope included developing PLS CADD model, selecting new route/poles locations, developing permit and construction drawings, environmental permitting support, cost estimates, construction packages, and ordering poles and materials.

Lauderdale - Palm Aire 138kV - FPL
Airport-Dade 138kV Line - FPL 

Line Project consisted of the replacement of existing wood pole structures and relocation of a portion of line thru Dade County School Board property/park. Project scope included permitting support for a new easement thru Dade County School Board property/park, replacing/upgrade of existing 556 ACSR conductor to 954 ACSR conductor, evaluation of existing structures and insulators for new conductor size, developing PLS CADD model, developing permit and construction drawings, cost estimates, construction packages, and ordering poles and materials.

Project consisted of an ampacity upgrade study on a section of line to increase ampacity from 1015A @75C to 1320A @115C and the replacement of five existing double circuit concrete H-Frames with two new single circuit round spun concrete poles. Project scope includes developing PLS CADD model, performing survey point clearance evaluation, selecting poles locations for the double circuit concrete h-frames replacement, developing permit and construction drawings, environmental permitting support, cost estimates, construction packages, and ordering poles and materials.

Coast-Myakka 138kV line ampacity upgrade - FPL
Grounding and Shielding Study - Alcan, Canada

Performed an evaluation and testing of approximately 50kM of 345kV line counterpoise grounding and bonding system to determine the line risk exposure to lightning strikes and the effective grounding of the towers.
