Our expertise includes large-scale poured-in-place flatwork, including slab-on-grade and slab-on-metal-deck systems, as well as heavy civil construction, structural foundations, retaining wall systems, post-tension slabs, and complex structural concrete projects.

Safety remains at the core of our operations. Tri-State maintains a comprehensive safety program that meets or exceeds OSHA requirements and is continuously refined to adapt to evolving project demands and industry standards.
From large commercial developments to specialized structural work, Tri-State Construction is committed to executing every phase of construction with professionalism, attention to detail, and a focus on long-term client success.
From a small foundation to a high-rise core, every job we touch runs on the same fundamentals.
Foundations, walls, slabs, columns, and finishes — all in-house. No daisy-chained subs, no finger-pointing, no schedule gaps between scopes.
Our BIM team models pour plans, generates shop drawings, produces total-station layout files, and surfaces RFIs early so the field never waits on coordination.
An internal safety program that meets or exceeds OSHA, refined for every site we work on. Site-specific plans, daily JHAs, and ongoing training.
We bid and self-perform every scope below. Bringing them under one roof is what keeps our jobs predictable on schedule and clean at handoff.
Tri-State has been measured against the same standards by general contractors and developers for nearly four decades. Here's what holds true on every job.
Our finishing crews carry American Concrete Institute (ACI) Flatwork Finisher certifications — meaning every slab is placed and finished to documented industry standard.
Union carpenters, laborers, ironworkers, and finishers on every project. Trained, drug-tested, and held to a higher standard for both safety and craftsmanship.
Internal safety standards that meet or exceed OSHA, with site-specific plans, daily JHAs, and continual updates based on field experience. Multiple OSHA 30-trained team members across leadership and field supervision. Current EMR: 0.78 — well below the 1.0 industry baseline.
An in-house BIM team and a safety culture that gets us invited back. Both are baked into how we run every job.
3D models, takeoffs, shop drawings, pour plans, CAD layout files for total-station robots, and early-issue RFIs to keep your project moving.
