At Tower Drafting Solutions (TDS), our Modification Drawings translate engineering‑determined structural actions into clear, ready‑to‑review documentation. Whether the project is driven by a structural analysis, a TIA‑mandated maintenance requirement, or a carrier‑initiated upgrade, we draft the exact steel and foundation modifications your engineers specify, consistently, and to your internal standards.

Our Process
TDS drafts directly from your engineering materials. No added interpretation only precise execution.
Once received, our team builds the full modification drawing package with accurate existing condition sheets, clear proposed condition overlays, dedicated modification detail sheets, and weld/hardware documentation.
Everything is formatted to your internal CAD standards, ensuring the drawings slot into your workflow without revision for formatting or structure.
SDDs, TIA‑MDDs, and analysis outputs are converted into unambiguous modification drawings that show exactly what must change—no clarification cycles required.
Capacity upgrades requiring reinforcement
Structural analysis reports
SDD/MDD templates and title block requirements
You handle the engineering. We deliver the drawings.
Used for engineering‑driven reinforcement or redesigns such as adding steel plates, modifying members, replacing bracing, or adjusting connection details. We ensure the drawings reflect the calculated solutions exactly as your engineer defines them, with zero interpretation or assumptions from our side.
Developed for TIA‑driven maintenance requirements—typically inspections or repair actions identified during compliance evaluations. All MDD packages follow your TIA maintenance template and annotation logic, ensuring seamless continuity with your deliverables.
Every modification package is drafted to support fast, efficient engineering review and ultimately, a smooth construction process. Our goal is simple: you handle the engineering; we deliver drawings that make your work easier, faster, and more consistent.
Clean, consistent sheet formatting across all markets
Accurate transcription of every engineering‑defined action
Logical sheet sequencing and detail placement
Readable and field‑friendly graphics
Efficient incorporation of revision cycles
Our drawings follow a strict internal standard to ensure clarity, accuracy, and zero formatting drift across all markets. Engineers get clean, ready‑to‑review plans every time.
We match our workflow to your schedule. With a scalable team and optimized CAD processes, we deliver predictable turnaround for both single‑site and multi‑market projects.
We speak your language. Technical redlines, structural notes, RFDS, and design intent are interpreted correctly the first time, reducing rework and back‑and‑forth.
