Substation Engineering

SEL provides complete engineering, procurement, and construction management services for substations. From design through construction, our multidisciplinary engineering services help ensure your project’s optimum cost effectiveness, quality, and overall success.

Procurement and Construction Management

SEL provides comprehensive solutions for substation engineering projects. Whether we are procuring turnkey components like substation control buildings or helping clients to prepare, receive, and assess material procurement bids, we ensure that everything meets both industry standards and your own project-specific requirements.Having SEL act as your agent in acquiring and commissioning major equipment and materials helps you ensure quality and control costs while keeping your project on schedule.When it comes to construction management, SEL has prequalified partners who provide construction services under the supervision of our on-site construction managers. If you have a preferred contractor, we will prequalify them as part of our supplier qualification process, making sure the contractor can support the project’s requirements.Our project managers ensure that standards and requirements are met at every step and that construction proceeds on schedule and within budget.

How We Ensure Your Project’s Success

SEL is an engineering company with 35+ years of leadership in the electric power industry—which means you can count on us to lay the complete engineering groundwork necessary for your project’s success. Our engineers, project managers, designers, technicians, and support staff are located in offices across the United States and around the world.At every stage of the process, SEL is your single source of accountability. SEL project teams are carefully chosen to meet the project’s objectives and will work closely with you to ensure that every part of the project meets industry standards and your specific requirements.

Quality Assurance

SEL maintains a documented quality system that is certified to ISO 9001 requirements.Our licensed professional engineers will work closely with you through the budgeting, conceptualizing, design, permitting, procurement, and construction process, making sure your requirements are met at every step. Projects are typically divided into five phases: planning; definition; development; testing and validation; and commissioning and construction.In the planning and definition phases, the SEL project team works with you to develop quality assurance checklists, which will be used to verify that work in each phase of the project meets requirements. Any hold/witness points or approval requirements that you define will be included in the detailed project plans.These crucial beginning steps help ensure that project requirements and the design basis are correct, building quality in from the start and saving time and effort for everyone in later phases.At each subsequent phase, the SEL technical reviewers and your team must each verify that the agreed-upon quality assurance benchmarks have been met before moving on.Throughout the project, SEL will communicate project status and provide opportunities for you to define requirements, review deliverables, and provide feedback on our performance.
