Our engineers coordinate the proposed equipment with the site's recorded loading and mount capacity, then carry those findings into the drawings and application materials. You receive a package that describes the same installation throughout. A new-tenant application can stall when the carrier's RF and antenna package reaches review before anyone has checked whether the proposed mount can support it. A structural finding then changes the equipment arrangement after drawings have been submitted. The tower owner returns the package, review starts again, and the installation date slips while the documents are corrected. Draftech owns that coordination from the start. Our new-tenant tower engineering services connect the capacity decision to the equipment layout before the application moves forward. Your team has a single point of accountability for the engineering package. ## What our tower colocation engineering services include The deliverables focus on the installation the new tenant intends to add to the selected tower. Each part supports the next, so a capacity finding reaches the drawings and the application materials together. - **Mount and structural capacity checks for the proposed tenant load.** Draftech reviews the proposed addition against the tower's current loading of record and the intended mounting configuration. This work is coordinated with our [structural engineering discipline](https://draftech.com/services/wireless-engineering/tower-structural-analysis/) under ANSI/TIA-222. The resulting findings establish the structural basis for the tenant layout. - **Tenant equipment layout and mounting configuration drawings.** We translate the carrier's supplied equipment requirements into drawings that reflect the capacity findings. The drawings show the carrier's antennas, radios and cable runs at the proposed mounting elevation, the mount that carries them, and how that equipment sits beside the tenants already on the structure. - **Construction-ready drawing packages.** Draftech develops the installation drawings once the structural question is answered. These drawings carry the supported equipment arrangement and mounting configuration into the documents used to build the new tenant's installation. - **Tenant application preparation support.** We help assemble and coordinate the technical materials for the tower owner's and carrier's review. ## Resolve capacity before completing the layout This work starts once the carrier has selected the tower. The next engineering decision is whether its proposed equipment can be supported in the intended configuration, considering the equipment already recorded at the site. Draftech starts with the tower owner's existing structural and appurtenance records and the carrier's proposed RF and antenna package. Those inputs serve different purposes. The owner records establish the existing site information used for the capacity review. The carrier supplies the proposed equipment requirements. Our engineers bring them together to evaluate the intended addition before committing the construction drawings to that arrangement. If a capacity finding requires a different mounting configuration or equipment arrangement, it must reach the carrier while the layout is still being resolved. Draftech coordinates the engineering implications with the carrier and tower owner, then incorporates the resulting direction into the package. The carrier remains responsible for its RF requirements. Answering the structural question first means the drawings start from a supported arrangement and the application never shows one the engineering does not support. ## Keep review comments connected to the whole package The tower owner and carrier need to review a coherent proposal. An application can describe the intended installation clearly and still cause rework if its equipment information differs from the drawings or the capacity check. Draftech checks consistency across those materials before handoff. When a reviewer requests a change, our engineers consider its effect on the connected deliverables. A revised mounting arrangement can affect the layout and its structural basis. The technical information accompanying the application may also need revision. For your project team, one engineering team is responsible for carrying that change through. You do not have to reconcile separate responses from structural and drawing vendors. Application preparation is part of the same scope. Draftech brings the engineering answer back into the package your reviewers are assessing. Application support here concerns the tenant's materials for tower owner and carrier review. If the project also needs a separate permitting workstream, our [wireless site permitting service](https://draftech.com/services/wireless-engineering/wireless-site-permitting/) addresses that scope. ## Start with the records behind the proposed installation Send the available tower owner structural and appurtenance records, the carrier's proposed equipment package and the applicable owner and carrier submission requirements. Include any drawings or review comments already prepared for this tenant addition. If an application has already been returned, the review comments help us understand where the package stopped. A request to change the mount has a different engineering consequence from a request to clarify information already shown. We review the comments alongside the proposed installation so the correction addresses the underlying issue. Tell us whether engineering has started and whether the package has reached review. If drawings already exist, we check them against the capacity findings before any of that work is carried forward. ## Is this the right service for your tower project? This service is intended for a carrier that is becoming a new tenant on the selected tower, including regional and rural carriers using an existing structure for their next installation. Tower companies use the same package when a new tenant is coming onto one of their own structures. The capacity check, the layout showing the new equipment beside the existing tenants and the construction drawings arrive together, so your reviewers assess the whole addition at once instead of piece by piece. If the carrier already has equipment on the tower and needs an upgrade, use our [existing-tenant modification service](https://draftech.com/services/wireless-engineering/macro-cell-modification/). If the carrier is still deciding whether to commit to a candidate site, start with [engineering-only site feasibility](https://draftech.com/services/wireless-engineering/site-feasibility/). Separate indoor projects belong with [in-building DAS design](https://draftech.com/services/wireless-engineering/in-building-das-design/).

We will review what you have, define the engineering scope for the tenant addition and tell you what is still needed from the tower owner or the carrier before the package can move forward.

Engage Draftech after the carrier has selected the tower and can provide its proposed equipment requirements. Bringing the package to us before the layout and application are completed lets our engineers resolve the capacity question before it drives drawing rework. We can also review an existing package that has been returned with technical comments. ### How is this different from ordering a standalone structural analysis? A standalone analysis answers the structural question alone. This package carries the capacity finding into the tenant layout, construction drawings and application materials. Draftech's in-house engineers perform both the capacity check and the drawings, so the finding reaches the layout without a handoff to another firm. ### Can you use the carrier's existing RF and antenna package? Yes. The package as the carrier issued it is the starting point: its antenna, radio and cable details and the proposed mounting elevation set the load the capacity check evaluates. A missing cable count or mounting detail is raised with the carrier before the check is run. If the carrier revises the package after the check, the capacity check is updated for the change. ### Does the package include building the new installation? The colocation package is the engineering package. Draftech also offers full turnkey construction , with Draftech-managed crews building macro site modifications and new towers under Draftech's QA/QC and safety program. ### Does application support guarantee tower owner approval? No, the tower owner and carrier retain their review decisions. Draftech prepares and coordinates the technical materials for review. When a reviewer comments, we revise the capacity findings, drawings and application materials together and return them to you as one package for resubmission.
