Fully Integrated Construction

Pre-engineered metal buildings require precise coordination from foundation to finish. Sentry’s self-performed approach means our Structural Steel division handles erection, our FieldWorks team coordinates foundations and anchor bolts, our Crane Service manages heavy lifts, and our Electrical and Mechanical divisions complete the building systems.

Need a crane-ready structure? Our Engineering team designs the tie-ins and our crews install them. The result is a complete building delivered by a single team with accountability from day one.

Challenges We Solve

  • Coordinating foundation work, erection, and finish trades across multiple contractors
  • Ensuring anchor bolt accuracy and foundation tolerances for proper PEMB fit-up
  • Integrating crane systems, mezzanines, and process equipment into the building structure
  • Meeting fast-track schedules with reliable erection crews and predictable timelines
  • Finding qualified teams for future building expansions, modifications, and structural repairs
