The marks might cover a different work area, an operator might require a meeting, or a private service might sit outside the one-call response. We treat those gaps as unresolved field conditions. This guide follows the decisions between planning an excavation and handing over a locatable installation. Our focus is telecom and utility work: what the excavator must verify, when work must stop and which records let a project owner reconstruct the decision afterward. ## Damage prevention starts with the 811 ticket lifecycle Underground damage prevention is the coordinated process of identifying buried facilities, confirming their locations and controlling excavation around them. It begins with an 811 request and continues through safe exposure and documented closeout. We require the crew to reconcile the ticket with actual field conditions before releasing the affected work area. ### Define and white-line the excavation area Access pits and equipment anchors need excavation space beyond the proposed conduit centerline, so include them when defining the footprint. Where state law requires white-lining, outline the proposed work before submitting the request; otherwise follow the state one-call center's accepted delineation procedure. Snow or inaccessible ground can require an approved alternative. On the ticket sketch, we look for the same limits shown in the field and on the current construction drawing. If the route moves beyond those limits after a conflict review, the supervisor must address the changed excavation area through the one-call process before digging there. The revised drawing still needs a ticket covering the expanded work area. The Common Ground Alliance Best Practices, particularly its excavation chapter, provide a consensus framework for this coordination. State one-call law supplies the binding notice requirements. Use 811 and the state one-call centers to identify the applicable procedure; a generic national checklist cannot calculate the legal start time for every job. ### Submit the ticket and respect the wait Before accepting the issued record, the requesting excavator should read it back and verify that its work description and location match the planned excavation. We want the named field contact to be reachable by the locator, with enough detail to distinguish the correct side of a road or the intended parcel boundary. Keep the issued ticket number accessible at the worksite. Normal notice periods commonly fall around 2 to 3 full working or business days, but state definitions and exceptions differ. Indiana 811's professional FAQs and Sunshine 811's ticket instructions illustrate that range. Confirm the legal start date and time with the applicable center, including its treatment of holidays and the submission day. Even if one operator marks early, the crew must wait for the legal start time and verify the remaining responses. Other notified operators may still have work to complete during that statutory waiting period. We also distinguish a design-information request from the excavation notice needed for the crew's actual work. ### Track ticket life and renewal A crew moving between states may encounter different expiration rules: the OKIE811 Excavator Guide and Sunshine 811 ticket instructions illustrate 14 to 30 calendar days, while other systems use different periods or working-day clocks. Those endpoints describe examples across states, not a selectable national window. Check your state's one-call law for the applicable expiration and renewal trigger. Record both the start of the validity clock and the deadline to begin excavation. Some rules distinguish the deadline to begin excavation from the period during which an active ticket remains valid. Our approach assigns renewal tracking to a named person who gives the field supervisor the actual expiration, so the crew can check it without inferring validity from visible paint. Schedule renewal requests far enough ahead of expiration to allow the required notice and marking process. A renewal request does not by itself authorize continued excavation after the current ticket expires. If marks disappear or work changes, follow the center's update or re-mark procedure even when the date printed on the old ticket has not passed. ## Read every positive response before release Positive response is the facility operator's report of its action on the locate request. Read the full code definition and any comments. We reconcile each notified operator against the response record, then compare that record with the worksite; an email saying responses are available is only a prompt to review them. When reading a response from an unfamiliar center, check its code definitions. The OKIE811 Positive Response guidance explains the operator-to-excavator communication function, while individual state centers define their own codes. The table below describes common response families and our recommended field decisions. It does not replace the applicable center's code list. | Response or condition | Meaning to verify | Excavator action | | --- | --- | --- | | Marked | Operator reports its facilities marked within the requested limits. | Find the marks, read comments and verify the covered area before exposure. | | Clear or no conflict | Responding operator reports no conflict within the stated scope. | Check scope and remaining operators; investigate contradictory field evidence. | | Meeting or standby required | Operator needs coordination before the affected work proceeds. | Arrange attendance and document the agreed protection conditions. | | Incomplete or delayed | Requested marking has not been completed. | Hold affected excavation and follow the center's escalation procedure. | | No response | No usable operator response is recorded. | Contact the center through its no-response procedure; do not treat silence as clearance. | | Marked, but marks missing | The electronic response conflicts with the visible site. | Stop affected work and request correction or re-marking. | ### Marked and clear responses need a field check A property owner's service may lie within the excavation even when a participating operator reports clear. That response covers the responding operator's facilities; it cannot establish that every buried object is absent. We ask the project owner to identify privately owned facilities and arrange qualified investigation when needed. The absence of a utility from the ticket distribution list deserves attention. For a marked response, walk the proposed excavation and compare the mark limits with the ticket. Cabinet entries and visible service connections can reveal a question that the response alone cannot answer. Do not extend a painted line by assumption or repaint an uncertain alignment as though the operator had confirmed it. The APWA uniform color code identifies facility categories; it does not certify depth or accuracy. Our [utility marking colors guide](/blog/utility-marking-colors) explains that vocabulary. Here, the decision is whether the markings and response together address the excavation being released. ### Resolve conditional and missing responses When an operator requires a meeting or standby, arrange it before releasing the affected work. We need the agreed limits and protection method recorded where the supervisor can retrieve them. Read the comments and every referenced attachment, then carry those instructions into the crew briefing so no condition goes unresolved because someone missed it. Under our release rule, affected excavation stays on hold for incomplete or missing responses until the applicable legal procedure and field protection requirements are satisfied. State laws differ on additional notices and nonresponse provisions. Do not improvise a deadline or interpret a delayed response as permission to dig through an unresolved facility corridor. ## Expose facilities inside the tolerance zone The tolerance zone accounts for uncertainty around a facility's marked position. Published state guidance commonly uses 18 to 24 inches beyond the facility's outside edges, but the definition and permitted excavation methods vary. The Mississippi 811 Excavation Manual and Kansas 811 guidance illustrate those endpoints. Verify your state's measurement rule before laying out the protected area. A duct bank occupies more width than a narrow cable, and the working envelope around its mark must account for that difference. We ask the operator to clarify unclear width or offset notation before the crew chooses an exposure location. Because marks generally indicate approximate horizontal position, the crew still has to verify depth. ### Use a controlled exposure method OSHA 29 CFR 1926.651(b) requires estimated underground utility locations to be established before excavation and exact locations to be determined by safe and acceptable means when work approaches them. Use careful hand excavation or an accepted vacuum method inside the tolerance zone, consistent with state law and the facility owner's requirements. Choosing hand tools or vacuum excavation still leaves the crew with damage risks to manage. Vacuum operators need training and facility-specific controls, particularly around vulnerable coatings or cable jackets. We require the selected method to account for the asset being exposed; the word vacuum on a work plan does not establish safe pressure or nozzle technique. Expose enough of the facility to confirm the conflict being evaluated. A single observation cannot prove an entire crossing or a long parallel alignment, particularly where the facility bends or changes elevation between visible structures without any indication on the surface. Record what was observed and leave unverified portions identified as uncertain. For a bore, carry the verified crossing information into the bore plan and the crew briefing before the drill advances through the conflict area. Our [HDD boring and fiber installation guide](/blog/hdd-boring-fiber-installation) covers the wider drilling sequence. A steering display cannot independently confirm an existing utility's position. ### Protect what the excavation reveals OSHA 29 CFR 1926.651(b)(4) addresses protecting, supporting or removing underground installations as necessary while an excavation is open. Obtain the facility owner's direction for protection and support; never move an exposed cable out of the way simply because the proposed trench needs room. For a project owner coordinating multiple crews, our [turnkey utility construction delivery](/services/utility-construction/) places construction under Draftech's QA/QC through Draftech-managed crews. We connect field conflict decisions to the construction package so a revised crossing instruction reaches the crew that will execute it. Damage prevention sits beside the excavation safety plan. It does not settle excavation-entry requirements; our [fiber construction safety and OSHA guide](/blog/fiber-optic-construction-safety-osha-requirements) addresses the separate worker-protection obligations. ## Stop for missing marks, conflicts or damage ### Missing or wrong marks Missing paint or an exposed facility that conflicts with the marks gives the supervisor a reason to stop the affected excavation. Keep equipment outside the unresolved area. Our next step is notification to the facility owner and one-call center through its prescribed incorrect-mark or re-mark request, retaining the new reference number for follow-up. The operator needs the affected station or work limit and a precise description of what the crew found, with ownership left uncertain if it has not been established. Request a field meeting when the operator and excavator cannot reconcile the condition remotely, especially if the exposed facility falls outside the marked corridor or has uncertain ownership. A moved stake or erased mark should never be repaired from memory. Before restart, we expect the supervisor to document how the condition was resolved, including the corrected information and any changed excavation method, then brief the crew again. Where the solution changes the route, confirm that the permit and construction drawing still cover the work being proposed. **Preserve the discrepancy:** Photograph the original marks and conflicting field evidence from a safe location before correction, so the record shows why work stopped. ### A strike, scrape or suspected contact If contact occurs or damage is suspected, stop immediately, keep people clear and follow the site's emergency procedure. For gas or electric hazards, call 911 from a safe location; do not approach the damage to obtain photographs or delay the emergency call while trying to determine liability. Notify the facility owner and the one-call center after immediate emergency actions are underway. PHMSA's excavation damage requirements in 49 CFR Part 196 require reporting pipeline damage to the operator, and a regulated gas or hazardous-liquid release requires a prompt 911 call. Follow the applicable state reporting requirements too. Even when service appears uninterrupted, report a coating scrape or damaged tracer wire and leave repairs to the facility owner's direction. The facility owner must evaluate the asset and direct the response; the excavator should not conceal it with backfill or assume that continued service proves the damage harmless. Keep bystanders away from potentially energized equipment and exposed conductors. Do not touch equipment and the ground simultaneously or attempt to free equipment from electrical contact. Follow emergency responder and utility instructions. We settle emergency roles before mobilization so the supervisor can act without searching for a contact chain. ## Build damage prevention into tracer wire and records ### Make the installed route locatable For the next excavator to locate the route, the installation needs a usable locating provision. PHMSA's Small Natural Gas Operator Guide explains how a conductive tracer allows a locator to identify the route of otherwise nonconductive plastic pipe. For nonmetallic telecom conduit, the design likewise needs an owner-approved locating provision suited to the installation. In our construction package review, tracer continuity and accessible connection points need defined requirements, inspection before backfill and acceptance testing under the owner's specification. A severed wire or inaccessible termination can defeat the intended locating method. Before backfill, photograph the connection point with enough surrounding context to identify it later. Our preferred record-based approach has a limitation: an accurate drawing cannot restore a broken tracer circuit or prove today's field position without verification. Keep the physical locating system and the documentation under separate acceptance checks, with the responsible inspector recording any defect that must be corrected before the owner accepts the installed route. Acceptance needs both results, since passing either check alone leaves the other question open. An owner reading the as-built needs explicit point labels to distinguish an observed facility position from a proposed alignment left on the drawing after a field change. Preserve the measurement reference and the method used to establish depth, especially where final grading will change the surface from which cover was measured. Our field records capture deviations as they happen, while the route is still visible and before restoration makes reconstruction harder. ### Keep records that support a damage claim Someone reviewing a damage claim needs to reconstruct what the crew knew when excavation occurred. Our recordkeeping advice is to retain original files and timestamps, then add corrections transparently so an investigator can distinguish a contemporaneous observation from a later explanation. That context makes evidence useful, though no claim file can guarantee a liability outcome. - **Ticket history:** Preserve ticket numbers, original work limits and each renewal with its response record. - **Mark photographs:** Take wide views tied to recognizable site features and close views showing the relevant markings before excavation. - **Pothole logs:** Record the exposed facility's identification, measured position and depth reference, including uncertainty or discrepancies. - **Daily reports:** Identify the crew and work area, with the excavation method and any stop-work or restart decision. - **Owner instructions:** Retain meeting notes and written protection directions, identifying who gave them and when. A photograph sitting anonymously in a phone gallery is hard to use during a claim review. We need to connect it to the ticket and the location it documents. Preserve the original file when adding labels, and avoid changing the apparent relationship between a mark and the exposure it documents. For [underground utility construction](/services/utility-construction/underground-construction/), carry the accepted field measurements into closeout so the owner receives a usable route record. Retention periods and claim procedures depend on the contract and applicable law. Agree on the required record format before work starts. ## Release decisions and the pre-excavation checklist **For crew supervisors:** Release only the defined work area whose ticket and field conditions have been reconciled. Hold a disputed crossing even if other portions of the route are ready. **For project owners:** Assign responsibility for private-facility investigation and for closing response gaps. Require a documented handoff when crews change, so the replacement supervisor receives the current conditions rather than an outdated ticket printout. Draftech International delivers turnkey telecom and power infrastructure, from field survey and planning through construction drawings, permits and agency coordination to construction, as-builts and closeout. Engineering is 100% in-house; construction uses Draftech-managed subcontract crews under Draftech's QA/QC. Our [partner leadership](/about) provides accountability across that work. Active in 24 states. Available across all 50 U.S. states. **Resolve the route handoff:** [Discuss utility conflicts and construction readiness with Draftech](/contact) before the work package reaches the crew. We coordinate unresolved utility conflicts and carry accepted field changes into the construction documents, addressing the gap between an issued ticket and a usable crew instruction. Draftech does not offer utility locating or subsurface utility engineering (SUE). For utility coordination on an upcoming route, reach us at [info@draftech.com](mailto:info@draftech.com). For owners planning a qualifying route, Draftech engineers the first 20,000 linear feet at no cost, from feasibility and field survey through permit approval. The [first-route engineering offer](/free-design) begins with the owner's review of each request before Draftech commits the package. ### Pre-excavation checklist - **Scope confirmed:** White-lining and ticket limits match the actual excavation. - **Ticket current:** The notice period has elapsed and validity covers the work. - **Responses reconciled:** Operator conditions and private-facility questions are resolved. - **Exposure planned:** The state tolerance zone and accepted exposure method are understood. - **Stop authority:** The crew knows when to stop and whom to notify. - **Records ready:** Preserve mark photos and maintain exposure logs and daily reports. ## Frequently Asked Questions ### What does damage prevention mean in utility construction? Damage prevention is the process of protecting buried facilities before and during excavation, then leaving records that support future work. An 811 request starts the notification process, but the crew must also reconcile responses and verify conflicts before digging. In our handoffs, a named person stays responsible for each work area, keeping unresolved conditions visible when supervisors or contractors change. ### How long should an excavator wait after contacting 811? Normal notice periods commonly fall around 2 to 3 full working or business days, but the applicable state law controls. Holidays and submission-day rules affect the legal start time, and an unresolved response can require further action. For our release decision, we use the state one-call center's stated start date and time and check every operator response before the affected work proceeds. ### How wide is the excavation tolerance zone? State guidance commonly uses 18 to 24 inches beyond a facility's outside edges, but the measurement rule and allowed methods differ. Confirm the applicable law and account for the facility width shown by the marks. When that width is uncertain, we ask for clarification before choosing an accepted exposure method and allowing equipment to approach the identified facility at the conflict. ### Does a clear 811 response mean every utility is absent? No. A clear 811 response describes the responding operator's finding for the requested work limits; other operators and privately owned facilities still need consideration. We compare that response with visible site evidence and the owner's records. If a service connection or an exposed object contradicts the response, hold the affected excavation and seek clarification before proceeding with that portion. ### What should a crew do after striking a buried facility? Stop the affected work immediately and keep people clear. For gas or electric hazards, call 911 from a safe location, then notify the facility owner and one-call center without delaying emergency response. Report suspected damage even when service continues, including coating or tracer damage; our evidence collection waits until it is safe, and the owner directs assessment and repair.
