You receive a circuit-level exposure and condition assessment, pole loading analysis, ranked selective-undergrounding recommendations, and hardening work packages ready for release. Engineering is 100% in-house, giving your utility a single point of accountability from the assessment through the issued drawings. A hardening program can replace poles with a class that still fails the next loading event. A segment may be committed to undergrounding before anyone compares it with overhead hardening options. The result is a hardening budget spent on work that does not change the circuit's exposure, or a work package that stalls on a decision that should have been resolved at the design table. Our engineers establish what each affected structure needs and document why the proposed treatment fits the circuit's exposure. Our grid hardening engineering services are part of Draftech's [electric utility engineering services](https://draftech.com/services/electric-utility-engineering/), so your utility's resilience investments rest on engineering completed before storm season. ## Assess exposure against the existing circuit The assessment connects your utility's circuit priorities and asset records to the structures within the proposed program. We review the available drawings, pole records, condition information, and hardening criteria, then verify the field conditions needed to support engineering decisions. Wind, ice, and flooding exposure inform the assessment without making every segment a candidate for the same treatment. We identify where the record supports a decision and where missing information could change it. An undocumented attachment can change the loading model. A guy arrangement shown in the records may differ from the arrangement in the field. The assessment records: - Circuit and segment boundaries tied to the utility's asset identifiers. - Exposure concerns and condition inputs supporting each segment's review. - Verified structure configurations and discrepancies in the source records. - Open assessment items tied to the affected structures. - Locations requiring overhead analysis, undergrounding screening, or both. This gives your engineering staff a defined starting point for review. A missing input remains tied to the decision it affects, so an uncertain pole class or attachment configuration cannot quietly become an accepted assumption across the program. ## Specify upgrades from the loading results Hardening requires a stated performance target. Draftech records the utility's hardening criteria, the wind and ice load cases the program designs to, alongside applicable National Electrical Safety Code (NESC) requirements so the reviewer can see where the criteria exceed code minimums and which load case governs each upgrade. The analysis then evaluates existing and proposed configurations against that basis. For each structure the program touches, we establish the proposed pole class, guying, and anchoring from the loading analysis. The recommendation identifies the governing load case and the configuration used to evaluate it. The guy direction and anchor lead assumed in the loading model are recorded against the structure identifier so the reviewer can confirm that the field-verified arrangement matches the analysis. We document the existing result, the proposed result, and the changes responsible for the difference. That comparison lets your reviewer see whether the recommendation addresses the identified loading limitation. It also distinguishes structures that need an upgrade from those the analysis supports retaining within the agreed hardening scope. For background on the underlying structural assessment, see our guide to [what a pole loading analysis evaluates](https://draftech.com/blog/what-is-a-pole-loading-analysis). This engagement applies that analysis to your utility's hardening targets and existing distribution assets. ## Rank undergrounding candidates against overhead options Selective-undergrounding screening answers a program decision: which segments warrant further conversion engineering after comparison with overhead hardening? Draftech evaluates candidates against the same exposure concerns used in the circuit assessment, then records the reason to advance, defer, or retain an overhead approach. For each candidate, we consider what the overhead upgrade can address, what exposure would remain, and what known site constraints could affect the value of moving the segment underground. Moving a segment underground removes its wind and ice exposure, but in a flood-prone area it puts pad-mounted equipment and below-grade connections at risk of water, so the screening weighs that against the overhead option. The screening gives your utility a ranked set of candidates with a documented rationale. Each entry names the overhead alternative considered and explains the exposure driving the preference. Open assessment items remain referenced in the ranking. Once your utility selects a segment, [overhead-to-underground conversion engineering](https://draftech.com/services/electric-utility-engineering/overhead-to-underground-conversion/) develops the complete conversion package as a separate engagement. The hardening program preserves the selection rationale so that subsequent engineering starts with a clear objective. ## Carry the decisions into hardening work packages Draftech translates accepted overhead recommendations into drawings that identify the affected structures and specify the proposed pole classes, guying, and anchoring. The hardening design package brings together: - The exposure assessment and design criteria governing the included segments. - Structure-specific loading results and the proposed upgrade configurations. - Drawings and details carrying the accepted overhead design decisions. - Undergrounding screening results, ranked candidates, and the utility's selection decisions. - Resolved review comments and any outstanding decisions affecting package release. An undergrounding recommendation remains identifiable as a recommendation for further engineering. The package distinguishes those candidates from completed overhead designs, preventing a planning selection from being mistaken for a finished design. Before issue, our engineers check that the proposed configurations agree across the analysis and drawings. If a review changes an anchor arrangement, the affected loading result and details receive corresponding revisions. Questions that could alter the design return to the utility before the affected package is released. Your utility can release completed hardening work packages to its own contractor or to Draftech's full turnkey construction, delivered by Draftech-managed crews. ## Define the boundaries with related utility programs Hazard-driven hardening can intersect other capital work on the same circuit. If you are designing a new line, see [overhead distribution design](https://draftech.com/services/electric-utility-engineering/overhead-distribution-design/). For a program driven by pole age or condition, [pole replacement engineering](https://draftech.com/services/electric-utility-engineering/pole-replacement-engineering/) addresses those replacement needs. This hardening scope evaluates an existing circuit against the exposure and performance targets your utility has identified. Where a hardening design touches shared poles, existing attachments become inputs to the affected structure models and design decisions. Pole owners can use [joint use engineering](https://draftech.com/services/electric-utility-engineering/joint-use-engineering/) for recurring attachment administration. Shared-pole work here is limited to the structures in the selected hardening segments. For procurement teams selecting a grid hardening engineering firm, our [electric distribution design firm selection guide](https://draftech.com/blog/electric-distribution-design-firm) provides a broader evaluation framework.

We can scope the assessment, loading analysis, and hardening design around selected segments within your utility's program. The scope identifies adjoining structure information needed to support the analysis and the boundaries of the delivered packages. ### How do you decide whether a stronger pole class is needed? We model the existing pole's class and setting, conductor sizes and span lengths, mounted equipment, and existing attachments. We check that model against the wind and ice loading cases in the utility's hardening criteria. The results establish whether the existing pole, a higher class, or added guying and anchoring carries that load. ### What happens when asset records conflict with field information? We identify the discrepancy and determine which engineering decision it affects. The input is resolved through field verification and utility review before it controls the final recommendation. ### What does the undergrounding ranking tell our capital planning team? It gives your capital planning team an order of priority for conversion engineering. A segment ranks higher when overhead hardening would leave more of its exposure in place and known site constraints do not weaken the case for moving it underground. Lower-ranked segments stay on the overhead hardening path unless your utility chooses to advance them. ### Can you work from hardening criteria our utility has already adopted? Yes. Your adopted criteria become the design basis for the loading analysis. If they do not define a load case for a structure type or exposure the program covers, we raise the gap with your engineering staff before that analysis runs.
