A&E drawings, equipment upgrade design, structural coordination, zoning drawings, and as-built records for macro cell site modifications — 5G overlays, C-band upgrades, antenna replacements, and new equipment installations. All 50 U.S. states. MBE-certified.
Macro cell sites — towers, monopoles, rooftops — require A&E engineering every time technology evolves. AT&T, Verizon, and T-Mobile run multi-market technology overlay programs at scale: 5G NR equipment additions, C-band spectrum additions, antenna swaps, remote radio head (RRH) additions, and equipment cabinet upgrades. Each modification requires updated permit drawings, structural coordination, utility notifications, and as-built documentation. Carriers don't maintain in-house A&E staff at the scale required for program rollouts — they use engineering firms to deliver the complete modification package.
Modifications at existing macro sites follow a different workflow than new small cell deployments. The permitting path is generally faster — colocation on an existing structure carries significant regulatory protections — but coordination complexity remains high across multiple stakeholders: the tower owner, the local authority having jurisdiction (AHJ), the utility, and the equipment OEM. Integration of structural analysis findings into the A&E package is a standard part of the workflow. A structural deficiency finding that arrives after A&E design is complete forces rework. Running both concurrently eliminates that schedule risk.
Draftech delivers complete A&E packages for macro cell modifications formatted to carrier program standards — from equipment upgrade design and permit drawings through structural coordination and post-installation as-built records.
Equipment layout drawings, antenna orientation and down-tilt documentation, cable routing diagrams, grounding plans, and mounting detail drawings formatted to carrier program standards.
Antenna replacement design, remote radio head (RRH) installation specifications, mounting configuration, and cable management for technology overlay programs.
TIA-222 structural analysis coordination, feasibility review integration, and modification recommendation documentation where structural deficiencies are identified.
Jurisdiction-specific zoning drawings, permit applications, and aesthetic documentation for modifications requiring local AHJ approval.
Complete bill of materials, construction document package for field crews, and traffic control plan coordination for ground-level modifications.
Post-modification as-built records — updated drawings, photographic documentation, and record submissions for tower owner and carrier inventory systems.
The primary volume driver for macro cell modification engineering is technology overlay programs. Carriers run these at multi-market scale — C-band spectrum additions required purchasing new spectrum licenses and upgrading equipment at tens of thousands of existing macro sites nationwide. 5G NR additions to existing 4G sites require antenna changes, mounting adjustments, and RRH installations that must be engineered to the site's specific structural and mounting configuration.
These programs run on tight carrier schedules and require engineering firms with multi-market concurrent delivery capability and standardized drawing formats that don't require revision cycles between markets. A carrier running a C-band overlay program across 12 states needs A&E deliverables that are consistent across every jurisdiction — same format, same detail level, same construction standards — regardless of which state or tower company manages the underlying structure. That consistency is what allows construction crews to work from the package without engineering support in the field.

Most macro cell modifications on existing structures fall under the FCC's Section 6409(a) collocation rights, which require state and local governments to approve antenna colocation modifications that don't substantially change the structure. Modifications that substantially change the structure — exceeding height limits, increasing ground equipment footprint, changing tower dimensions — are subject to standard zoning review. Draftech evaluates whether a modification qualifies for 6409(a) processing or requires full zoning review before preparing the permit package.
Yes. Multi-market concurrent delivery is the standard engagement model for carrier overlay programs. Draftech assigns dedicated program management and maintains standardized drawing formats and construction document templates across all active markets. Carriers receive consistent deliverables regardless of which state or jurisdiction a site is in.
The A&E package and the structural analysis run concurrently. If structural analysis identifies deficiencies that require modification before the equipment upgrade can proceed, Draftech incorporates the structural finding into the A&E design — adjusting mounting configurations, recommending load redistribution options, or flagging pole replacement requirements. The goal is a single coordinated package, not two separate deliverables that have to be reconciled.
Whether you're running a 5G overlay program across multiple markets or processing a single-site equipment upgrade, Draftech delivers complete A&E packages to carrier program standards. All 50 U.S. states. MBE-certified.
