Watertown, SD
Sentry completed the construction of its Manufacturing & Operations Facility in Watertown, South Dakota using a Nucor pre-engineered metal building system designed to support long-term operational flexibility, manufacturing support, and future growth across multiple self-performing divisions.
Serving as both an operational headquarters and a showcase of Sentry’s design-build PEMB capabilities, the project highlights the flexibility, scalability, and durability of Nucor Building Systems across commercial, industrial, manufacturing, and operational environments.
The facility combines office space, fabrication support areas, operational staging, training space, electrical infrastructure, controls & automation support areas, fleet coordination, and large-scale open operational floor areas into one integrated facility designed around workflow, operational efficiency, and long-term functionality.
Constructed using a Nucor pre-engineered metal building system, the facility was intentionally designed to support large-scale operational flexibility, clear-span functionality, and long-term industrial durability.
The PEMB system provided:
The project serves as a real-world example of Sentry’s experience delivering Nucor PEMB solutions through design-build coordination, self-performed construction support, crane coordination, and integrated project delivery.
As a Nucor Building Systems partner, Sentry provides complete PEMB project coordination for commercial, industrial, manufacturing, service, and operational facilities across multiple markets.
The facility was designed around operational workflow, accessibility, and long-term functionality.
Site planning included:
Integrated workflow planning between departments
Large open-span operational areas combined with centralized support spaces allow the facility to adapt to changing operational demands while supporting continued growth across multiple divisions.
The completed facility reflects Sentry’s approach to self-performing construction, operational planning, and integrated project delivery while also serving as a showcase of the company’s Nucor PEMB capabilities, industrial construction expertise, and long-term operational vision.
Sentry served as the General Contractor and provided overall project management, design-build coordination, and self-performed construction support throughout the development of the facility.
The project required close coordination between multiple in-house divisions, operational teams, vendors, subcontractors, equipment logistics, fabrication support functions, and PEMB construction activities to create a facility designed around long-term operational performance and future growth.
Project management responsibilities included:
The project was intentionally designed to improve coordination between office personnel, field operations, fabrication support teams, electrical operations, manufacturing support, and service divisions while supporting future expansion and operational flexibility.
As a self-performing contractor, Sentry utilized internal divisions throughout the project wherever possible to support quality control, communication, scheduling efficiency, and overall project execution.
The project included coordination and support for:
The completed facility reflects Sentry’s integrated project delivery model and ability to coordinate multiple divisions under one operational structure while maintaining flexibility throughout the construction process.
Sentry’s South Dakota Service Division played a major role in supporting field execution, operational coordination, and PEMB construction activities throughout the project.
The SD Service team supports a wide range of field operations including PEMB erection, crane & trucking services, fabrication support, welding services, millwright work, preventative maintenance, and industrial field support operations.
The project included coordination of:
Dedicated operational areas were also incorporated into the facility layout to support ongoing field operations, material coordination, equipment storage, and long-term service capabilities.
Sentry’s Electrical Division self-performed the electrical scope associated with the facility and helped support the operational infrastructure required throughout the building.
The Electrical Division scope included support for:
The facility layout also includes dedicated electrical operational and storage areas designed to support field operations, equipment coordination, material organization, and long-term operational growth.
The completed facility reflects Sentry’s ability to integrate electrical operations directly into overall project planning and operational workflow.
Sentry’s Controls & Automation Division was also integrated into the facility planning and operational layout.
The facility includes dedicated space supporting controls & automation operations, training, electrical coordination, storage, and support for Sentry’s UL-certified panel shop capabilities.
Sentry’s Controls & Automation Division provides:
The integration of these operations within the facility helps improve collaboration between divisions while supporting operational efficiency, fabrication coordination, project execution, and long-term scalability.
The facility was intentionally designed to support Sentry’s manufacturing and fabrication operations through integrated operational planning, material handling coordination, fabrication support space, and long-material staging capabilities.
Open operational floor areas allow flexibility for:
The site layout also supports coordination between structural steel operations, fabrication support activities, field operations, and project execution teams while improving overall workflow between divisions.
In addition to large-scale operational and manufacturing support areas, the facility was also designed to support Sentry’s administrative, project management, engineering, and operational coordination teams under one centralized location.
The integrated office layout provides space for:
The combination of office, operational, and manufacturing support space within one coordinated PEMB facility allows for improved communication between departments while supporting long-term operational efficiency and future growth.
The completed facility demonstrates the flexibility of Nucor pre-engineered metal building systems to support both professional office environments and large-scale operational functionality within a single integrated structure.
Sentry delivers design-build PEMB solutions backed by self-performing experience, operational planning, and disciplined project execution across commercial, industrial, manufacturing, and service environments.
