Engineering expertise,
shared and applied.
A dual-purpose engineering practice. Freelance structural work for contractors and engineering teams on one side, an open technical library on the other: articles, guides and calculation tools built from the same projects.
Bridging the gap between structural theory and job-site execution.
We do not just calculate concrete, we build resources. Tension One LLC exists to make post-tension engineering legible, through a mix of hands-on technical support and open material.
To engineer, consult and educate
The mission rests on four pillars:
- Design support. Tendon layouts, profiles, calculation notes and design documentation for post-tensioned slabs.
- Technical consulting. Third-party structural review and field problem solving.
- Industry resources. Books, calculation sheets and tools for fellow professionals.
- Open knowledge. A technical blog dedicated to real post-tension slab problems, 32 articles and counting.
Deliverables are issued as independent technical support. Sealing and approval remain with the licensed engineer of record on the project, as set out in our disclaimer.
The reference PT hub for Texas
The aim is for contractors to trust us with their structural calculations, and for engineers to reach for our guides and tools when they need to move their own work forward.
Our story and founder
Civil engineer specializing in structural design and post-tensioned slab systems. Works across design, field coordination and structural optimization on residential, commercial and industrial projects.
How the content here is produced
Articles are drafted with AI assistance, then reviewed and technically validated by a civil engineer before publication. Every technical claim is checked against the relevant ACI or PTI document with its edition named, every worked example is recomputed, and corrections are applied openly. The full process is written down in the editorial policy.
