"Best" is a claim. A general contractor or a developer choosing an earthwork subcontractor in North Texas is not choosing a claim; they are choosing a company whose paper can be checked before the iron arrives. This guide is written from the buyer's side of the table. It says which documents to ask for, what each one proves, what it cannot prove, and the Texas rule that makes each one matter. Most of them can be requested in one email, and a contractor worth hiring has them ready.
Start with workers' compensation, because Texas is different
In most states an employer must carry workers' compensation insurance. In Texas, except for public employers and as otherwise provided by law, an employer may elect to obtain it1, and the Texas Department of Insurance says plainly that private employers can choose to carry coverage but that it is not required in most cases2. An employer that does not carry it must notify the state's workers' compensation division in writing, must tell every new employee at hiring whether coverage exists, and must post a notice of whether the employer has coverage at its place of business1. A non-subscriber that is sued by an injured employee may not raise the defenses that the employee was contributorily negligent, assumed the risk, or was hurt by a fellow employee's negligence1. For public work the question is closed by statute: a governmental entity that enters a building or construction contract must require the contractor to certify in writing that it provides workers' compensation coverage for every employee on the project, and each subcontractor must provide the same certificate through the general contractor1. So the first document is the workers' compensation certificate, and the first question is whether the earthwork contractor is a subscriber at all.
Read the certificate for what it is
A certificate of insurance is the document everyone asks for and few read correctly. Under the Texas Insurance Code it is a statement or summary of property or casualty coverage issued to a third person who is not a party to the policy, and it may not alter, amend or extend the coverage or terms of the policy it references, nor convey a contractual right to the certificate holder3. Every certificate form used in Texas must be filed with and approved by the insurance commissioner and must carry the phrase "for information purposes only" or a statement that the policy controls3. What an approved, properly executed certificate does do is confirm that the referenced policy has been issued or that coverage has been bound3. It may not reference the requirements of any other contract, including your construction contract3. The consequence for a buyer is simple: the certificate proves a policy exists, and the additional insured and waiver endorsements you actually need have to be requested as the endorsements themselves, because the certificate cannot carry them.
The safety record is three OSHA forms
Employers record work-related injuries and illnesses on OSHA Forms 300, 300A and 301, and every employer covered by the Act must report a work-related death to OSHA within 8 hours and an in-patient hospitalization, amputation or loss of an eye within 24 hours5. The 300A, the annual summary, must be posted in each establishment from February 1 through April 30 of the following year6, and establishments of certain sizes and industries submit it electronically to OSHA each year between January 2 and March 257. A company that had 10 or fewer employees at all times in the previous calendar year is not required to keep the records at all, though it must still report fatalities and hospitalizations8. Ask for the last three years of 300A summaries. They carry the case counts a buyer can compare across bidders, and a contractor with 25 people who cannot produce one either did not keep the record or does not want to show it.
The experience modification factor, and what a 1.00 really means
The number that turns a safety record into a single figure is the experience rating modification factor, the mod. The National Council on Compensation Insurance computes it by analyzing an employer's actual payroll and loss data over a period of time, usually the latest available three years, against similarly grouped employers; an employer with better-than-average loss experience receives a credit mod below 1.00, and one with worse-than-average experience carries a debit mod above 1.009. The caution most buyers miss is in the same document: an employer receives a unity factor of 1.00 when it does not meet the eligibility or minimum data requirements, or when it is a new business with no data available9. A 1.00 on a company that has been in business for two years is not a clean record. It is no record yet. IRONWILL Earthworks was founded in July 2024, so we say this about ourselves before anyone asks: judge us on the logs and on the sites, and read the mod for what it is.
Competence is a person, not a card
OSHA 10-hour and 30-hour cards are the most common training proof in construction, and OSHA's own program page says the Outreach Training Program is voluntary, does not meet the training requirements of any OSHA standard, and is not a certification; cards are issued by authorized trainers, and OSHA keeps no record of the classes10. The cards are useful evidence of a company's habit. They are not the thing the standard requires. What the standard requires on an excavation site is a competent person, defined as one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them11. Ask who the competent person will be on your site, by name, and whether that person will be there every day. The equipment standard is checkable the same way: seat belts on the machines, a horn on every bidirectional machine, and a reverse alarm or a spotter for anything with an obstructed view to the rear12. A walk through a contractor's yard answers those in ten minutes.
Bonding is the financial statement you can actually see
For public work in Texas the bonding rules are statutory. A governmental entity must require a performance bond on any public work contract over one hundred thousand dollars and a payment bond on a contract over twenty-five thousand dollars, or over fifty thousand dollars where the entity is a municipality, each in the amount of the contract and executed by a corporate surety4. A payment bond beneficiary who wants to recover on the bond must mail notice to the prime contractor and the surety on or before the 15th day of the third month after each month in which the labor or material was furnished4. For a private buyer the value of those rules is indirect: a surety that will write a performance bond for an earthwork contractor has examined that contractor's financial statements, equipment, backlog and history far more closely than a buyer ever can. Ask for a letter from the surety stating the single-project and aggregate limits the contractor is bondable to. It is the one financial disclosure you will get without asking for a balance sheet.
The 811 record shows how a crew actually digs
Texas law requires anyone who intends to excavate with mechanized equipment to notify a notification center not earlier than the 14th day and not later than the 48th hour before the excavation begins, excluding Saturdays, Sundays and legal holidays, and the notice must carry the location, the excavator's contact information and the start date and time13. If an excavation damages an underground facility, the excavator must immediately contact the operator, or a notification center if the operator is unknown13. Violations carry a civil penalty, and the board may instead require the excavator to attend an approved safety training course13. A contractor's locate tickets are a record of discipline. Ask how tickets are managed, who confirms the marks before a machine moves, and how a strike would be reported. The answer tells you whether the 48 hours is a habit or an obstacle.
Federal readiness is a registration, not a promise
A contractor that says it pursues federal work should be registered in the System for Award Management, which is what allows an entity to bid on government contracts and assigns it a Unique Entity ID, and the registration must be renewed every 365 days to stay active14. The registration is public. IRONWILL Earthworks is registered and veteran-owned, and a buyer can confirm the first fact in SAM in a minute.
The fleet, and whether it reads the model
The last thing to evaluate is the iron, and the question has changed in the last decade. The Federal Highway Administration describes automated machine guidance as construction equipment with onboard computers that use 3D engineered models and GPS to guide the operator horizontally and vertically in real time, with the potential to reach designed grades on the first pass and to raise productivity by up to 50 percent on some operations15. Ask how the contractor checks grade against the engineer's model while the work is going on: machine control on the blades, GPS rovers, laser setups, or a combination. Any of them works when the model is right and the checking happens as the dirt moves rather than at the end. A contractor who cannot say how it checks grade is a schedule risk the bid does not show.
