The company delivers interior finish and specialty trade services across nine core solution areas — architectural woodwork, ceilings, door/frame/hardware, general construction, glass and glazing, medical equipment, metals, science furniture and equipment, and specialties — serving aviation, healthcare, education, entertainment, government, hospitality, science and technology, and commercial end markets through 25+ regional offices in North America.

ISEC differentiates through a digital construction technology stack comprising Virtual Design and Construction (BIM on 300+ projects), laser-scanning reality capture (125+ projects), Trimble precision tooling (100+ projects), AR/VR visualization, 3D-printed prototypes, and 360-degree site documentation, combined with self-performed labor (700+ field craft professionals) and a global manufacturing partner network that supplies architectural woodwork, laboratory furniture, doors/frames/hardware, and specialty items. The firm operates 48 specialty contractor licenses in 29 states, holds $224M+ in assets, and maintains a 0.79 Total Recordable Incident Rate (60% below industry average), a 20-year ENR Top 100 ranking, and LEED credentials across 428 projects.

ISEC's commercial model is project-based specialty contracting delivered through two go-to-market motions: (i) subcontracting for general contractors on large-scale construction projects with active contracts exceeding $1.9B, and (ii) a fast-growing Direct-to-Owner segment covering life sciences, healthcare, and hospitality projects. The company reached a $500M revenue goal in 2023, completed more than $10B of contracts over its lifetime, and formalized its ESOP structure in 2024 to lock in employee ownership across 600+ employee owners under the Vision 2030 growth plan.
