Project Experience
What We Do
At ARC Engineering, LLC, we specialize in a diverse range of projects, with a strong focus on substation design. Our team of experienced engineers is dedicated to creating tailored solutions that meet the unique needs of our clients.
69kV – 25kV Substation Design
Certainly, substation design is a critical aspect of our work. We take immense pride in our unrivaled expertise in this field. Consequently, we understand the pivotal role it plays in advancing electrical infrastructure. Not only do we specialize in design, but we also offer comprehensive services covering every aspect of electrical substation projects. We also excel in designing and implementing state-of-the-art substations that adhere to the latest industry standards and regulations. Likewise, if your existing substation requires enhancements, our team is ready to meet the challenge. Furthermore, we provide ongoing maintenance and optimization solutions to ensure your substation consistently operates at peak performance levels. Therefore, you can rely on us for the entire lifecycle of your substation project.
Navigating the Design Process
The process of substation design is complex and multi-faceted. It typically involves initial feasibility studies and site selection. Consequently, the design phase encompasses electrical layout, equipment specifications, and protection system design. Subsequently, the construction phase includes site preparation, foundation work, and the installation of critical equipment. Post-construction, our team ensures that the substation operates efficiently, offering maintenance and optimization services to meet long-term operational goals.
Our Substation Design Services for 69kV Relay
Our substation services encompass:
VA Water Treatment Plant
This project involved the phased replacement of outdated PLC hardware at a municipal water treatment plant to improve operational reliability, data visibility, and regulatory compliance. The project was executed without interrupting daily operations, thanks to a carefully sequenced installation strategy and temporary wiring configurations. Deliverables included full system modeling, and hands-on training for plant staff. The upgrade enhanced reliability of the plant by eliminating hardware that was no longer available through the OEM and reprogrammed the software to the latest versions.
As Built Drawings
Our team provided comprehensive as-built drawing services for a combined-cycle power plant following major equipment upgrades and system retrofits. The project involved field verification of electrical, mechanical, and structural systems, including switchgear layouts, cable routing, and transformer placements. Using a combination of redline markups, and site surveys, we developed accurate CAD-based as-built drawings reflecting all modifications from the original design. Deliverables included updated single-line diagrams, conduit and cable schedules, and revised elevations for the electrical gear. These documents were formatted for integration into the facility’s asset management system and used to support future maintenance, safety audits, and regulatory compliance. The project improved operational transparency, reduced troubleshooting time, and ensured alignment with IEEE, NEC, and owner-specific standards.
