Who we are

We take pride in providing the finest finished product in the structural engineering and steel detailing industry saving our clients money and most importantly, TIME!


Connected Structural Engineers [CSE], is the partnership of Raymond R. Khoury, P.E./S.E. and James C. Warner, P.E. joining together to provide clients unique and complex structural solutions for casino, commercial, high-rise hospitality and condominiums, and public building projects. Working with the design team and contractors, CSE delivers projects from inception through all phases of structural feasibility, design and construction contract administration.

Connected Structural Group [CSG], is owned by James C. Warner, P.E. specializing in structural engineering, structural steel detailing, steel connection design, steel erection engineering, BIM modeling development, LOD 400-500 coordination with steel fabrication, and related services. CSG produces production models, not design models. This commitment to detail is what sets us apart in the industry.

Both firms combined, offer clients depth of resources and the highest level of expertise for unique project types nationwide.


Meet the Team



Structural engineering

With licensed structural and professional engineers having years of experience in large to small scale projects, we can provide structural design for concrete, steel, masonry, and other types of structures. Whatever material is used, our structures are designed with fabrication, erection, and construction in mind to save the owner, fabricator, and contractor both money and time in the overall project schedule. Engineering services for erection procedures and temporary structures.


structural steel detailing

Detailed fabrication drawings using SDS/2 steel detailing software. The SDS/2 modeling system enables us to prepare 3D models of entire steel structures including all information required for ordering, fabricating, and erecting steel. Our steel detailing services also include assembly drawings, advanced bill of materials and anchor bolt layouts and templates. Our in house, licensed engineers are able to identify potential design problems in the detailing phase for projects engineered by other firms, adding another level of safety for the design team, fabricator, owner and contractor.


building information modeling

Building information modeling (BIM) is the move from analog to digital design and construction. It is a model-based technology linked with a database of project information. BIM has transformed the way that projects are created, communicated and built. Benefits of BIM include reduced risk, improved productivity, streamlined productions and improved quality control through better communication. BIM provides the client with initial cost savings that later extend to the operations and maintenance of the facility.
