Reverse Engineering Process
The Problem with Standard Approaches
A typical wireless site is not a single, integrated product — it's a custom-built system assembled from 20–30 major components and hundreds of smaller parts, each combination engineered to meet a specific coverage and capacity objective. No two sites are identical.
General cost manuals and broad asset classifications were not designed for this level of complexity. Applying them to wireless infrastructure produces valuations that are, at best, imprecise — and, at worst, legally indefensible when challenged by well-resourced telecom companies. Think of it like trying to appraise a custom-built aircraft using a catalog price for a factory model — the parts might overlap, but the engineering and labor that makes it fly are entirely different.
CTS was built specifically to solve this problem. Our visual reverse-engineering process creates a true component-level inventory of each site, forming the factual backbone for every inventory and cost estimate project.
A Rigorous Two-Part Model
CTS's valuation model is structured to produce a legally defensible, fully auditable statement of value — grounded in engineering reality, not generalized assumptions. Part One: Accurate Component Inventory. By systematically reverse-engineering each site, CTS meticulously identifies and catalogs every major component. The result is the most accurate inventory possible, serving as the factual foundation for the build cost model . It's analogous to an engineer reconstructing a bill of materials for a complex machine that was built without a blueprint: methodical, precise, and traceable. PartTwo: Cost Estimation. Built from the detailed inventory, our value grid closely replicates the Original Cost of constructing the site from scratch. This is far more than a parts list — it incorporates complex labor modeling to capture design, installation, integration, and project management costs. Like estimating what it would cost to rebuild a bridge rather than simply buy its steel, the full economic reality of the asset is reflected in every figure.
The CTS Valuation Process: Step-by-Step
Step 1 — Initial Site Analysis: Review of available public records, site permits/engineering drawings, and other publicly available data to establish the location/access and anticipated site configuration before starting field work.
Step 2 — Information gathered during the site visit: The process starts with high resolution photos of the site and the critical components both at the base and on top of the tower. The systematic breakdown of the site's visible infrastructure into its core components includes—antennas, Remote Radio Units (RRUs), base station equipment, cabling, and structural elements.
Step 3 — Component-Level Cost Calculation: Detailed cost estimation for each identified component, drawing on proprietary data and deep knowledge of major wireless equipment manufacturers and vendors. Each line item is grounded in the most accurate and fair information available.
Step 4 — Complex Labor Modeling: Specialized labor costs — engineering, design, installation, systems integration, and project management — are individually accounted for. This is the step most valuators skip, and it's often where the largest cost gaps live.
Step 5 — Final Asset Cost & Depreciation: Labor costs are applied to the asset cost estimates, producing a total figure submitted to the county appraisal department. From there, proper useful life schedules or state-supplied depreciation factors are applied to arrive at the final assessed value.
