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.
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.
Ampacity upgrade study on a section of line to increase ampacity from 1015A @75C to 1320A @115C. Rebuilt of a 2 mile section of line consisting of double circuit H-Frames with single pole double circuit structures. 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.
ECF was contracted to design a new 5.6 mile 69kV transmission line with distribution underbuilt that will be placed within the existing right-of-way. The new vertical framed pole line installation will be designed using steel monopoles. All dead-end steel monopoles will be guyed. All unguyed poles were designed as direct embed with concrete backfill. Scope of work included preparing permit drawings, detailed PLS CADD design modeling, bill of materials, structural analysis, Geotech, and coordination with local third-party municipalities.
ECF was contracted to perform the engineering to replace eight (8) 230kV concrete H-frame structures on the Andytown-Dade and Flagami-Sheridian 230kV lone with eight (8) total vertical framed single spun concrete poles. The score of work included preparing permit drawings, detailed PLS CADD design modeling, bill of materials, construction book, structural analysis, Geotech, and coordination with local third-party municipalities.
ECF was contracted to perform design analysis and review of transmission lines to access new and existing clearance violations. The proposed mitigation strategies for clearance violations included structure replacement, transmission structure reframes, distribution structure replacements, distribution structure reframes and third-party attachment relocation coordination. Scope of work included preparing permit drawings, PLS CADD design modeling, bill or materials, construction book, structural analysis, and coordination with distribution.
ECF was contracted to perform engineering for a temporary seven (7) pole transmission line to connect Chambers and Gracewood transmission lines for installation of a mobile switch at Tulip Substation. The scope of work included preparing permit drawings, PLS CADD design modeling, bill of materials, construction book, structural analysis, and coordination with vendor substation group.
ECF was contracted to perform engineering to replace the existing 954 ACSR/AZ conductor with new 1431 ACSR/AW conductor for an ampacity increase from 1475 amps to 1905 amps. The scope of work included structural analysis of dead end and tangent structures for new conductor size. ECF reviewed clearances with new conductor size and adjusted as necessary (structure replacements). ECF also prepared permit drawings, custom MOT drawings, environmental permitting support, and construction books. The scope of work included preparing permit drawings, custom MOT drawings, PLS CADD design modeling, bill of materials, and construction book.
