for commercial & industrial structures


With in-house dedicated software development teams, we are continually investing in the improvement of our processes and software systems.


With all of our project management team based in the USA and production teams working multiple shifts, our clients receive timely and accurate communication.


From advanced modeling software to highly detailed drawings and tracking controls, our technological capabilities help us produce accurate and timely products.


We utilize Tekla Structures, Revit, 3DS Max, and other industry leading software in our processes while adhering to all licensing guidelines.


Since LTC's inception in 1985, our philosophy has remained simple. We aim to provide our clients with the absolute best virtual design & construction services available.

For steel fabricators, this is accomplished by providing fabrication files for our clients’ shop equipment along with accurate 3D models and clear, concise, shop drawings. We prepare those drawings to an individual fabricator’s shop standards or steel detailing style, and even coordinate your project from start to finish.

Our Services

Visualization Services

LTC has a dedicated team of 3D visualization and simulation specialists who can create everything from a basic 3D rendering to a video depicting the simulated construction of a complex structure.
connection modeling

Connection Modeling

We work closely with engineers of record and connection engineers to build, connect, and review (in the model) complex steel connections prior to shop drawing production.

Preconstruction Services

Whether referred to as IPD or another acronym, we are often hired directly by the structural engineer of record, architect, or general contractor to produce a 3D BIM model prior to subcontractor award. Our rendering and animation teams are capable of producing work that can help a contractor or owner to visualize the construction process or final product.

BIM Coordination

With our model serving as the virtual jobsite, we integrate and coordinate across a variety of trades to identify and resolve clashes early in the project timeline.
Building Info Modeling BIM

BIM Modeling

As part of the BIM team, we use our model to resolve conflicts and issues early in the detailing process. More often than not, our models serve as the virtual jobsites for each project.

Shop Drawings

We produce quality shop drawings to each individual fabricator’s standards and preferences. With knowledge of all common industry machinery, LTC not only creates individualized drawings, but also CNC files which read into our customers’ machinery seamlessly.

On the leading edge of technology and innovation since 1985. 


"LTC goes beyond computer generated drawings, and works as a bridge between the engineer and fabricator, providing solutions that make everyone successful."
"LTC continually challenges themselves by taking on projects beyond the magnitude of what they've typically done. They knew they could do it, and we knew it too."
"LTC has included within its systems the means to integrate drill lines, plate processors, and coping machines, which has helped stream line our processes."
LTC provides shop drawings and CNC files that are accurate and thorough. We know we can trust the work provided by LTC.

LTC is a leading virtual design & construction (VDC) firm, providing world class preconstruction through project turnover services to architects, engineers, contractors, and fabrication shops across North America. From its founding as a steel detailing company, to its evolution as a building information modeling (BIM) solutions provider, to its most recent expansion into project visualization and simulation, LTC has always put clients first. Never striving to be the largest firm in the marketplace, but with a continuous focus on providing the best product and service, the firm has grown steadily to over 200 employees since its founding in 1985. With continuous investment into software customization and development, LTC’s clients receive service and products that are specific to their individual needs, and efficiently produced in a timely manner.
