Construction Project Management
Our team of EHV project managers have extensive experience in the construction, maintenance and upgrade of transmission, distribution and fiber optic systems, including large-scale EHV projects throughout the mid-west and western United States involving all aspects of line work with extensive use of helicopters. Primavera P6 and Construction Manager are our primary tools used to provide all functional aspects of document control, communications, reports and data support. Our project controls, accounting, QA/QC and Safety programs are fully integrated to further support the rigors of third party audits that project financing require.
The following recent major EHV projects, which were completed within schedule and budget, were led by our project management team:
Bangor Hydro 345 kV Transmission Line PC: InfraSource Transmission Services (ITS) was responsible for environmental mitigation and compliance (EMS), procuring, and constructing a total of over 82 miles of new transmission line consisting of materials procurement, Q/A, access road construction, drilling over 1000 wood pole footings, pier foundations, processing concrete foundations, wood H-structure installation, and helicopter stringing of two bundle conductor. All of this high performance was accomplished ahead of schedule without a major incident.
The Hanford Area Transmission Project included the construction of 62 miles of the Schultz – Wautoma No.1 500 kV Transmission Line, re-routing of the Sickler – Schultz No. 1 500 kV transmission line near the Schultz Substation, construction of the Hanford – John Day No. 1 Loop into the Wautoma Substation, installation of the Wautoma – Columbia Fiber System, and the installation of the Wautoma Tie Fiber System. Maslonka was responsible for EMS, access road construction, ROW clearing, and foundation survey. Maslonka’s in house fleet accomplished over 1 million tons of excavation and placement of grillage foundations in material ranging from solid rock to wet river bottom, lattice steel assembly and helicopter erection, triple bundle conductor installation, and OPGW installation. All of this high performance was accomplished ahead of schedule without a major incident.
Los Banos to Gates 500 kV Transmission Line EPC: Maslonka was the EPC firm and responsible for engineering, procuring, and constructing a total of over 85 miles of new transmission line consisting of ROW procurement assistance, design, Q/A, EMS, ROW clearing, access road construction, drilling over 1100 pier foundations, processing concrete foundations, assembling lattice towers, helicopter erection and stringing bundle conductor in a total of 15 months. Fast track procurement methods enabled significant improvements to the critical path schedule. For example: the first 1 million pounds of lattice steel towers was designed, procured, and delivered within 90 days of notice to proceed. Maslonka crews constructed new access roads, tower pads, and improved existing access roads. Maslonka’s in house fleet of 5 production drills completed the over 1100 piers foundations in material ranging from solid rock to wet river bottom (up to 11’ diameter and 60’depth). The Firm’s assembly line foundation crews completed all stub angle and rebar bolt cage foundations ahead of a compressed schedule, including processing wet foundations. Maslonka crews assembled and erected over 246 steel lattice towers and 96 steel tubular poles. Maslonka strung the triple bundle 1590 ACSR and shield wire in less than 8 months. All of this high performance was accomplished without a major incident.
AEP’s largest project for FY2002, this EPC transmission line construction project was a joint effort with AEP, which transferred ownership to LCRA (Lower Colorado River Authority). The project consisted of approximately 70 miles of 345kV double circuit transmission line with one circuit of two bundle 1590 ACSR and shield wire from West Texas Utility’s Red Creek Substation to an interconnect with Oncor (TXU). This project encompassed all of Maslonka’s core competencies, including ROW procurement assistance, EMS, right of way clearing, access road construction, foundations, lattice tower assembly and erection, and conductor installation. The construction phase of this critical ERCOT project was delivered in a record 11 months with significant performance bonuses achieved without a major incident.
