# Texas Civil and Underground Utility Contractor Insurance and Surety URL: https://mycontractorsinsurancequote.com/texas/audiences/civil-infrastructure-contractors Updated: 2026-10-29 · Reviewed by the Principal, Gleason Insurance Brokers, LLC Publisher: My Contractors Insurance Quote, a website of Gleason Insurance Brokers, LLC In Texas, an excavator who fully complies with the one-call rules in Utilities Code chapter 251 is generally not liable for damage to a facility that was not marked as the chapter requires, which makes the locate ticket part of the liability defense. TxDOT work adds a second gate: prime bidders must be prequalified, and bidding capacity is tied to audited working capital. Those two rules shape a civil contractor's liability, pollution and surety program more than the policy forms do. ## Key Decision Points - Call the notification center no earlier than the 14th day and no later than the 48th hour before digging, excluding weekends and legal holidays. - Full compliance with chapter 251 can shield an excavator from liability for unmarked facilities under §251.157(c). - After a strike, report immediately, leave repairs to the operator and hold backfill until a repair schedule is agreed. - TxDOT prime bidders need prequalification, and capacity on construction work rests on an audited CPA statement. - Payment bond claimants on Texas public work must mail notice by the 15th day of the third month after the work. ## The Texas One-Call Window and Marking Deadlines Utilities Code §251.151 requires a person who intends to excavate to notify a notification center not earlier than the 14th day before excavation and not later than the 48th hour before it begins, excluding Saturdays, Sundays and legal holidays. A Saturday notification allows digging to begin at 11:59 a.m. the following Tuesday, or Wednesday if the Monday is a holiday. Section 251.157 then requires each Class A operator contacted to mark its facilities by the same 48-hour mark, using the American Public Works Association color code, or at a time the operator and excavator agree. The 14-day outer limit matters on long linear jobs. A utility crew that calls in an entire corridor at mobilization may find its earliest tickets stale before the trench reaches them, so ticket management is usually phased with the schedule. Insurers writing underground work often ask how tickets are requested, tracked and renewed. They also ask whether the field superintendent can show the ticket for the segment being dug. That question is about the defense of a future strike claim as much as about safety. Trade-by-trade exposures for utilities, HDD, excavation and paving are explained on the hub for [underground utility contractor insurance](https://mycontractorsinsurancequote.com/who-we-serve/civil-underground-utilities). ## Why Full Compliance Changes the Liability Answer Section 251.157(c) states that an excavator who has fully complied with chapter 251 may not be liable for damage to an underground facility that was not marked in accordance with the chapter. That is a statutory allocation of fault in the excavator's favor, but it only applies to full compliance: a late call, a dig outside the ticket area or a missing record can take it away. Facility owners and their insurers pursue strike damages actively, so the ticket, photos of the marks and the dig log are often the most valuable documents on the claim. For the insurance program, this means underground facility damage is rarely a pure coverage question. A general liability policy may respond to property damage to a third party's line, while some forms limit or exclude underground resources and equipment unless restored by endorsement, and a contractors pollution policy may be the policy that responds when a strike releases product. The contractor's documentation practices can affect whether a claim is defended on liability, which is why underwriters tend to ask about them before quoting. When a strike releases fuel, gas or sewage, the question turns to [project-specific pollution coverage for utility work](https://mycontractorsinsurancequote.com/contractors-pollution-liability-insurance/project-specific-pollution). ### Illustrative scenario: A TxDOT Drainage Job and a Fiber Line Strike A Texas underground contractor wins a $6 million TxDOT drainage and culvert contract after updating its Confidential Questionnaire with a new audited statement, because its prior capacity, tied to working capital, was nearly used up. Midway through, its crew strikes an unmarked fiber line. The superintendent produces a locate ticket called in 72 hours before the dig and inside the 14-day window, plus photos showing no fiber marks, then stops work and calls the operator under §251.159. Because the contractor fully complied with chapter 251, §251.157(c) gives it a strong defense to the fiber owner's damage claim. Meanwhile a pipe supplier to a subcontractor sends a §2253.041 notice to the surety for an unpaid month, and the surety asks the contractor to resolve it before supporting the next TxDOT bid. ## Duties After a Strike and the Penalty Exposure If an excavation damages an underground facility, Utilities Code §251.159 requires the excavator to contact the operator immediately, or a notification center if the operator is unknown. Only the operator or someone it authorizes may make repairs. The excavator must delay backfilling in the immediate area until the damage is reported and a repair schedule is agreed, and where flammable material is present it must keep ignition sources away. Backfilling over a nicked line to keep a crew moving is the kind of decision that can turn a small claim into a large one. Section 251.201 makes an excavator that violates the notice, ticket information or damage duties liable for a civil penalty of $500 to $1,000, with higher penalties for other violations, and the board may instead issue a warning letter and require safety training. Civil penalties are often uninsurable, but the facts behind them frequently feed third-party claims. A contractor's incident procedure for strikes typically names who calls the operator, who stops work and who documents the site before anything is backfilled. Stormwater, lien and repose rules that apply to every Texas project are summarized under [Texas state construction law summary](https://mycontractorsinsurancequote.com/texas). ## TxDOT Prequalification and Bidding Capacity TxDOT qualifies bidders before they can bid or receive a bid proposal; subcontractors do not need to be prequalified. For most construction projects the route is the Confidential Questionnaire, which requires an audited financial statement prepared by an independent CPA firm, with a balance sheet less than one year old and positive net working capital. TxDOT defines bidding capacity as the maximum dollar value a contractor may have under contract with TxDOT at any given time, and for questionnaire holders it is calculated from net working capital multiplied by a factor TxDOT sets. The Bidder's Questionnaire covers smaller construction, routine maintenance, emergency and specialty work. Contractors on it are limited to $1 million of capacity unless they submit a compiled or reviewed statement. TxDOT will not consider internally generated financials, and prequalification packets must arrive at least 10 days before the letting. The same audited statement usually anchors the contractor's surety line, so the timing of year-end, the CPA engagement and the work-in-progress schedule affect both TxDOT capacity and bond capacity. How sureties read the same financial statement is explained in the guide to [contract surety for highway and utility work](https://mycontractorsinsurancequote.com/construction-surety-bonds). ## Captives for Texas Civil and Utility Contractors Texas civil and utility contractors with steady liability losses sometimes study a captive for a retained general liability or excess layer. Required auto liability under permits typically stays with an authorized insurer under Insurance Code section 964.051, and public construction work calls for certified workers' compensation coverage under Labor Code section 406.096, which a Texas captive may not write. That leaves the captive question focused on liability layers the contractor can predict, and a feasibility study usually tests whether utility-strike and fleet severity make that layer too volatile. What chapter 964 allows is set out under [Texas captive limits for civil contractors](https://mycontractorsinsurancequote.com/construction-captive-insurance-programs/texas). ## Payment Bond Claims on Texas Public Work Civil subcontractors and suppliers on Texas public work are usually protected by the prime contractor's payment bond rather than a lien. Government Code §2253.041 requires a claimant to mail written notice of the claim to the prime contractor and the surety on or before the 15th day of the third month after each month in which the claimed labor was performed or material delivered, with a sworn statement of account. A second-tier supplier of pipe or aggregate that waits for the job to finish can lose its rights for the early months. For a prime contractor, those notices are an early warning. A surety that receives a notice of claim will typically contact the principal for a response, and unresolved claims weigh on future bonding. Civil contractors that run their own monthly payment reconciliation against subcontractor and supplier accounts tend to see fewer notices arrive at the surety. The bond protects the claimants, and the contractor and its indemnitors owe the surety for anything it pays. The surety's side of a claim is explained under [payment bond obligations and claims](https://mycontractorsinsurancequote.com/construction-surety-bonds/payment-bonds). ## Before You Ask for a Quote ### What to Gather - Locate ticket logs by segment, with call dates and marking confirmations - Written strike-response procedure and recent incident files - Audited CPA financial statement and the current TxDOT questionnaire and capacity - Work-in-progress schedule and backlog for the surety - Subcontractor and supplier payment reconciliation for bonded public jobs - Equipment schedule, including HDD rigs and vacuum excavation units ### What to Ask the Insurer or Surety - Does the liability policy limit underground resources and equipment, and can it be restored by endorsement? - Would a release from a struck line fall under the general liability policy or the contractors pollution policy? - Does the insurer want ticket and photo documentation in a particular form for strike claims? - How will the surety treat a new audited statement prepared mainly to raise TxDOT capacity? - What will the surety do when it receives a §2253.041 notice of claim on one of the contractor's bonds? - Are civil penalties under §251.201 excluded, and are defense costs for related third-party claims available? ## Broker Notes **Quick Answer:** Texas excavators must call a notification center no earlier than the 14th day and no later than the 48th hour before digging, excluding weekends and holidays. Full compliance with Utilities Code ch. 251 can bar liability for damage to facilities that were not properly marked. **Common Mistake:** Calling in a whole corridor at mobilization and digging later segments on stale tickets. That can cost the excavator the §251.157(c) compliance defense on a strike claim. **Broker Perspective:** A broker reviewing a Texas civil contractor asks how tickets are tracked by segment, whether underground damage is limited in the liability form and how the audited statement supports both TxDOT and surety capacity. **Coverage Impact:** Strike claims may fall under general liability, contractors pollution or neither, depending on the forms and endorsements. Statutory penalties are often uninsurable. Payment and performance bonds protect the obligee and claimants, and the contractor owes the surety indemnity. ## Questions Buyers Ask ### How far ahead can I call in a locate ticket in Texas? Utilities Code §251.151 sets both limits: notify a notification center not earlier than the 14th day before excavation begins and not later than the 48th hour before, excluding Saturdays, Sundays and legal holidays. A Saturday call lets you start the following Tuesday at 11:59 a.m., or Wednesday if Monday is a holiday. On long jobs, tickets are usually requested in phases. ### Who pays if I hit a line that was never marked in Texas? If you fully complied with chapter 251, §251.157(c) says you may not be liable for damage to a facility that was not marked as the chapter requires. The defense depends on proving compliance, so the ticket, the dig area and photos of the marks matter. Your liability insurer will typically ask for those records before responding to the facility owner. ### What does TxDOT need to set my bidding capacity? For most construction work, TxDOT's Confidential Questionnaire requires an audited financial statement from an independent CPA firm, with a balance sheet less than one year old and positive net working capital. Capacity is net working capital multiplied by a TxDOT factor. Contractors on the Bidder's Questionnaire are limited to $1 million unless they submit a compiled or reviewed statement. ### My supplier wasn't paid on a Texas county job. What deadline does it face on the bond? Under Government Code §2253.041, the supplier must mail written notice of the claim to the prime contractor and the surety by the 15th day of the third month after each month in which it delivered the unpaid material, with a sworn statement of account. Each month has its own deadline, so waiting until the job ends can forfeit the earlier months. ## Official Sources 1.
