FSI is a full service architecture firm, blending the scientific and artistic elements of building design. We specialize in interior and exterior building investigation, preservation, and restoration. All of our services can be tailored to specific client needs.
How can we help you?
Architecture
Architecture is more than building design—it’s about shaping spaces that perform, inspire, and endure. At FSI, we guide each project from initial concept through construction with a proven, results-driven process. Our work is anchored in four essential phases: Discovery, Design, Development, and Construction Drawings, ensuring clarity, precision, and control at every step. To further protect our clients’ investment, FSI also provides construction-phase project management oversight, keeping projects on track, aligned with the original vision, and free from costly missteps.
Engineering
Engineering transforms technical expertise into smart, reliable building solutions. At FSI, we apply scientific rigor and real-world experience to solve complex building challenges and achieve clearly defined project objectives. Our integrated engineering services cover every critical building system—including structural, mechanical, plumbing, electrical, and life safety design—ensuring performance, efficiency, and long-term reliability from concept through construction.
Building Forensics
Forensic Investigation reveals the hidden conditions that impact building performance, safety, and longevity. Using a rigorous scientific approach, FSI investigates both existing and historical conditions to uncover the root causes of building failures and deficiencies. Our building forensics services focus on the comprehensive evaluation of structures and systems through targeted probing, testing, and hands-on physical inspections. This thorough, evidence-based process allows our team to assess building integrity with confidence and deliver clear, actionable insights.
Preservation and Restoration
Building Preservation and Restoration balance technical expertise with respect for architectural heritage. Preservation focuses on sustaining a building’s historic fabric, while restoration accurately re-establishes original form, materials, and detailing. FSI has developed specialized expertise in both disciplines, allowing us to thoughtfully extend the life, character, and cultural value of historic structures while meeting modern performance standards.
Project Management
Project Management ensures vision becomes reality through disciplined planning, coordination, and execution. Whether a project involves architecture, engineering, or an integrated combination of both, FSI provides expert oversight to guide each phase with clarity and control. Our proactive approach improves efficiency, reduces risk, and significantly increases the likelihood of successful outcomes—helping clients stay on schedule, on budget, and free from costly surprises.
