This included a 138-kV switchyard and transmission tie line. Our scope of work included electrical testing and commissioning services. Sargent & Lundy was the engineering subcontractor to M. J. Electric of Iron Mountain, MI for this EPC contract. The project was completed in 2003.
City of Anaheim Public Utilities Department
Sargent & Lundy is supporting the City of Anaheim, CA in a major upgrade/expansion of its transmission and distribution system. Sargent & Lundy is serving as owners engineer and construction manager for a series of gas-insulated substation (GIS) projects located in both enclosed and outdoor facilities. These projects include the following:
Park Substation
69 kV/23.8 kV indoor/underground GIS, placed in-service in 2006. Project Profile: Park Substation Project
Lewis - Vermont Project
230kV/34kV GIS in an open-air substation and a 230-kV transmission line, scheduled to be completed Fall 2007.
Anaheim Substation
69 kV/13.8 kV indoor GIS located in downtown Anaheim, scheduled to be completed Spring 2008.
Colorado River Commission
The River Mountains Project consists of two 230-kV transmission lines in the vicinity of Boulder City, Nevada. The project was developed jointly by the Colorado River Commission (CRC), Nevada Power Company (NPC) and the Southern Nevada Water Authority (SNWA). The transmission lines, which extend approximately 30 miles from the Western Area Power Administration Mead Substation to CRC's Newport Substation and NPC's future Equestrian Substation, include rebuilds of two of NPC's existing 69-kV transmission lines as underbuilt circuits. The lines were constructed on lattice steel towers and tubular steel poles. Sargent & Lundy performed construction inspection services for this project. Completed in 2001.

Exelon
ComEd
Working together with Exelon's Contractor of Choice (COC) teams led by Kenny Construction Company and Infrasource, S&L is performing engineering for a number of 138-kV and 345-kV substations throughout northern Illinois. In addition to engineering, S&L coordinates the electrical testing and commissioning of each substation and performs construction quality control services. As Exelon's Engineer of Choice, S&L is coordinating nuclear plant switchyard modifications during refueling outages. In addition, S&L and the COC team has been working on a series of major, enclosed substation projects for the ComEd in Chicago's central business district.

Nevada Power Company
Our staff performed engineering, permitting support and other services for a number of 69-kV and 230-kV transmission lines in the Las Vegas area. This included the 13-mile Nellis-Apex and Apex Relocation 69-kV lines, which replaced deteriorated wood-pole structures with light-duty steel poles. The Del Webb 2000 project involved the relocation of three existing 230-kV lines for a major residential development. The Arden- Northwest project included 17 miles of quad-circuit line. The McCullough-Arden #2 transmission line consisted of 15 miles of 230/138-kV quad-circuit line and the Crystal-Harry Allen project included approximately 10 miles of double-circuit 230-kV lines. S&L has also provided construction quality control surveillance personnel for a number of Nevada Power transmission line projects.
Centennial Project
The 29-mile Harry Allen - Northwest 500-kV Transmission Line, which was a component of Nevada Power's Centennial Project, was designed by Sargent & Lundy. This line was constructed on single-circuit and double-circuit steel poles and lattice towers. This project was completed in 2003. Sargent & Lundy also performed structural analysis of 500-kV tower designs for use on the Northwest - Mead segment of this project. We evaluated existing tower designs for use with Nevada Power's conductors, loading criteria and tension limitations. This work was completed in 2004.
Harry Allen - Mead
Sargent & Lundy is performing construction management services for this 500-kV transmission line project, including monitoring of compliance with project permits and grants of easements from federal agencies and inspection of access road construction, foundation installation, tower assembly and erection, wire stringing. The route crosses rugged desert terrain, presenting challenges to structure access and foundation installation. Our construction management team is on-site throughout the project duration and includes personnel experienced in all aspects of transmission line projects. Project Profile: Harry Allen-Mead Project
