The short answer

On a data center commissioning contract, your real pay is the hourly W2 rate plus overtime, per diem and travel reimbursement, minus any costs the contract leaves to you. Before you accept, get the rate, the overtime rule, the per diem amount and how it is paid, the travel policy and the conversion terms in writing, then compare offers on the full package rather than the headline rate.

What hourly rate actually means on W2 contract

A W2 hourly rate means you are an employee of the staffing firm or the employer, not a 1099 contractor. Taxes are withheld from your paycheck, the employer pays its share of payroll taxes, and you are typically covered by workers compensation and unemployment insurance.

Hourly W2 employees who are not exempt are generally owed overtime at one and a half times the regular rate for hours over 40 in a workweek under federal law, and some states add daily overtime rules. Commissioning schedules often run long weeks near turnover, so the overtime rule matters as much as the base rate.

Ask whether benefits such as health insurance, paid time off and a retirement plan are offered during the contract period, and when they start. A slightly lower rate with benefits from day one can be worth more than a higher rate without them.

  • Is the rate W2 or 1099?
  • How is overtime calculated, and is it approved in advance?
  • Which benefits are offered during the contract, and when do they start?

Per diem and travel reimbursement

Per diem is a daily allowance for lodging, meals and incidentals while you work away from home. When it is paid under an IRS accountable plan and you maintain a tax home away from the job site, it is generally not taxed as wages. That is why per diem is often quoted separately from the hourly rate.

Many employers set per diem with reference to the federal GSA rates for the project location. Ask whether per diem is paid for every day of the assignment or only for days worked, and whether it continues on weekends you stay on site.

Travel reimbursement is separate. Confirm who books and pays for flights at the start and end of the assignment, whether trips home are covered and how often, and whether mileage or a rental car is reimbursed. Your own tax situation is specific to you, so check the details with a tax professional.

  • What is the per diem amount, and is it paid daily or weekly?
  • Is it paid on weekends and days off?
  • Which travel costs are reimbursed, and how quickly?

What 95 percent travel looks like week to week

A 95 percent travel role means you live near the project, not at home. In practice you are on site most weeks for the length of the assignment, often in a hotel or extended stay rental, with trips home on a schedule the project allows.

Commissioning hours follow the project. Early phases can be steady, while integrated systems testing and turnover often bring longer days, weekend work and shift coverage. Ask what the current phase is and what the next few months are expected to look like.

Be honest with yourself about what this means for family, health and commitments at home. The right role is one you can sustain for the full contract, not just the first few weeks.

  • What is the typical weekly schedule on this project right now?
  • How often can I travel home, and who pays for those trips?
  • Is there a rotation, or is it continuous on site time?

Contract-to-hire conversion

Contract to hire means you start as a contract employee with the intent of being hired directly by the employer at the end of the contract period, if both sides want to continue. It is an intent, not a commitment, and conversion depends on the employer's needs and your performance.

When you convert, the pay structure usually changes. An hourly rate with overtime and per diem may become a salary with benefits, a bonus plan and a different travel policy. Ask what the converted package is expected to look like before you start, so you are not surprised later.

Ask who decides on conversion, when that conversation happens and what happens to your travel and per diem if you convert while still on the same project.

  • When is conversion typically discussed?
  • Is the converted role salaried, and what is the expected range?
  • Do travel and per diem change after conversion?

Questions to ask before you accept

Get the key terms in writing before you resign from a current role or book travel. A clear offer protects you and the employer, and any reputable recruiter or employer will provide one.

If you are comparing more than one offer, put the full package side by side: rate, expected overtime, per diem, travel, benefits and conversion terms. That comparison usually makes the decision clearer than the headline rate alone.

  • Who is my legal employer during the contract?
  • What is the hourly rate, and how is overtime paid?
  • What is the per diem, and how is it paid?
  • Which travel costs are covered, including trips home?
  • How long is the contract, and what happens if the project ends early?
  • What are the conversion terms and the expected converted package?
  • Who do I contact on site, and who handles payroll questions?
