ASEC’s primary skillset is in detailed electric transmission engineering. ASEC performs complete line design and analysis using PLS-CADD and other support software. ASEC’s employees are experienced in new transmission line design, reconductoring and re-build projects, easement and clearance assessments/remediation packages, and designing new communication cables on existing transmission lines. ASEC has extensive knowledge of industry leading standards such as NESC, ASCE-74, and the G.O. 95 codes for line analysis and can offer solutions for unique line design problems. ASEC can provide standard or customized construction packages and provide support throughout the execution phase of the project including onsite support as needed.
In its over 30 years of experience, ASEC has provided Owner Engineer (OE) insight on transmission engineering design for utilities across the US. These OE roles have included on-site structural inspection and damage analysis, forensic engineering, and the implementation of quality control processes. Through leadership in the industry codes and standards activities, ASEC engineers are recognized as experts and valuable training resources. ASEC’s investment in the Power Delivery industry is proven by our willingness to train others (utility and consultants alike) and to present updated methods of analysis and design across the industry at conferences and conventions.
ASEC’s engineers have designed and detailed complete families of 138kV, 230kV, 345kV and 500kV lattice towers and tubular steel pole families as well as other unique and unusual structures. Many structures have been full-scale tested. ASEC can provide the needed supervIsIon and project management for any structure development project whether that be towers or poles.
SCOPE At the completion of construction for each project, ASEC performs as- built engineering analysis on the structures and lines design has been performed on. Additional LiDAR survey data is received and ASEC compares the proposed design to the final constructed...
SCOPE A new substation was added to provide better protection schemes to include protective relays and a breaker addition. This resulted in the existing line needing to deadend and cut-in into the new substation. OPGW was spliced at multiple locations for the...
SCOPE ASEC performed detailed design on a family of six tapered tubular engineered steel poles. The poles were designed for 345kV double circuit configurations with two shied wire positions. ASEC created load tree drawings, electrical clearance diagrams, steel weight...
SCOPE ASEC is supporting a client’s civil/structural team and transmission engineering team with integrating the latest LiDAR data into existing PLS CADD models in support of their PCS Addition program. PROJECT DESCRIPTION The finalized up-to-date PLS-CADD models are...
SCOPE ASEC supported a 26-mile project that consisted of 17 miles of overhaul-rebuild and an additional 9 miles of OPGW Fiber addition to the existing transmission line structures. The existing H-Frame line was converted to delta-monopoles. PROJECT DESCRIPTION The...
SCOPE The program consists of single pole replacements from wood to steel on structures from 69kV up to 230kV with distribution and communication underbuild. ASEC has completed design replacements on over four hundred and fifty wood poles and the work is on-going....
SCOPE The purpose of the Structural Modeling Program (SMP) is to give Transmission Asset Management a uniform and global view of the health of the transmission system as it relates to mean strength values derived from PLS-CADD’s finite element analysis software....
