Primary frame across seven zones
The 1,150-ton structural and miscellaneous steel package was organized into Erector Zones 1–7 for phased fabrication, delivery and erection.

Project overview
Structural and miscellaneous steel delivered as one coordinated package.
The Spartanburg City–County Administration Building project involved a comprehensive structural and miscellaneous steel package for a new public administrative facility in downtown Spartanburg, South Carolina.
Working for SteelFab, our team detailed approximately 1,150 tons of steel. The scope extended beyond the building’s primary structure to include stairs, railings, access systems, support framing, bollards and perimeter lintels.

Detailing scope
Seven erection zones supporting an efficient construction sequence.
Four stair systems and access steel
The scope included Stairs #1–#4, clock tower and maintenance stairs, and a ship’s ladder.
Interior and exterior railings
Railings were detailed for the lobby, council chamber, clock tower, plaza, exits, exterior areas and curbs.
Bollards and operable wall supports
Miscellaneous steel included removable and embedded bollards together with support framing for operable walls.
Galvanized perimeter lintels
Angle lintels around the building perimeter were coordinated with their architectural locations and adjacent construction.
Sequenced drawing and material releases
Deliverables followed fabrication priorities and planned erection progress, covering both structural steel and miscellaneous metals.
Technical complexity
Managing a broad steel scope across multiple building areas.
Consistency across seven erection zones
Model information, review packages and material releases needed alignment with phased fabrication, delivery and installation.
Distributed stairs and railing locations
Miscellaneous components were spread across public, service, exterior and clock tower areas, requiring location-specific coordination.
Architectural and perimeter interfaces
Operable wall supports, galvanized lintels, bollards and railings had to remain coordinated with the primary structure and adjacent construction.
Two detailing scopes progressing together
The estimate comprised 2,223 structural hours and 689 miscellaneous-metal hours, requiring disciplined information management between the packages.
Our approach
From the primary frame to the final railing connection.
Our detailing workflow treated the structural steel and miscellaneous metals as coordinated parts of a single building package.
The primary frame was developed according to the erection-zone sequence, while stairs, railings, access components and support framing were coordinated with their specific locations and adjacent systems.
This approach helped create clear, fabrication-ready information for SteelFab across the complete scope of work.
Seven erection zones supporting an efficient construction sequence.
The primary structure was organized into Erector Zones 1–7. This division allowed detailing information to be aligned with the project’s planned fabrication and erection sequence.
Organizing the building into defined zones supported:
- phased drawing and material releases,
- coordination of fabrication priorities,
- planned delivery sequences,
- alignment with erection progress,
- more manageable review and approval packages.
The zoned workflow provided a practical structure for managing the project’s 1,150-ton steel scope.
Project result
A coordinated package built around fabrication and erection priorities.
By organizing the main structure into seven defined erection zones, the detailing process supported an orderly progression from fabrication through delivery and field installation.
The combined scope represented an estimated 2,912 detailing hours:
- 2,223 hours for structural steel,
- 689 hours for miscellaneous metals.
The result was a comprehensive steel package covering both the building’s primary structure and the numerous secondary components required throughout the facility.
