Based in New York City, Khalil Structural Engineering, PLLC provides structural engineering services to architects, owners, developers, and contractors across residential, commercial, mixed-use, and industrial sectors.
Khalil Structural Engineering was founded by Saif Khalil, PE in 2026 to provide high-quality, safe, and efficient structural engineering for buildings across the New York metropolitan region.
The practice focuses on new construction, restoration, adaptive reuse, and forensic investigation. We collaborate closely with architects, owners, developers, and contractors throughout the project lifecycle, providing clear engineering guidance from early design through construction.
Our licensed Professional Engineers bring deep technical expertise in new construction, adaptive reuse, restoration, and forensic engineering, with an emphasis on constructability and code compliance.
Structural modifications, strengthening, and rehabilitation of existing buildings. We work closely with you to determine the current structural capacity and develop practical, economical solutions within the constraints of aging and occupied buildings.
Wall removals, extensions, vertical enlargements, and full-gut renovations.
Office, retail, hospitality, healthcare, and real estate developments.
Visual and non-destructive surveys of concrete and steel structures. Quantification of structural deficiencies (cracks, delaminations, spalls, steel section losses), followed by restoration design — patch repairs, epoxy injection, CFRP flexural strengthening, and other rehabilitation.
We specialize in the design and analysis of complex foundation systems where site constraints and soil conditions dictate the strategy. From deep pile foundations to underpinning, we develop precise, site-specific details for footings, pile caps, and retaining walls.
Mission-critical industrial facilities and high-voltage utility sites. Our expertise encompasses the design of structural steel and concrete foundations.
3D drafting and modeling using advanced Building Information Modeling to ensure seamless integration with architectural, structural, and MEP systems.
Advanced finite element modeling for complex steel, concrete, and masonry structures, plus foundation design including mats, combined footings, pile caps, grade beams, and slabs-on-grade.
We use ENERCALC to design beams, columns, and retaining walls.
We provide the structural drawings and the calculations to back them up.
Direct involvement from concept through construction.
We work as part of your team — not just a consultant.
We design in accordance with ASCE 7, ACI 318, AISC, NDS, TMS, and applicable state and local building codes.
We can transform aging structures into modern spaces by strengthening existing framing using the latest technology, including carbon fiber strengthening and near surface reinforcement.
Drawings detailed for clarity, simplicity, and constructability.
