Temp-to-perm staffing in construction puts a skilled tradesperson on your site as a W2 employee of the staffing agency, then moves them onto your payroll once both sides are confident it is a fit. Direct hire puts them on your payroll from day one. Temp-to-perm buys you proof before commitment; direct hire buys you speed of ownership. At Cruitfly, conversion happens on average at around 480 regular hours worked, and direct hire placements carry a 90-day guarantee.
The choice matters more now than it did a few years ago. In the AGC and NCCER 2026 Workforce Survey, 87 percent of the 1,830 responding firms had openings for hourly craft positions, and 88 percent of those said the positions were as hard or harder to fill than a year earlier. When good trade workers are that scarce, a wrong permanent hire costs you twice: once for the hire, and again for the search to replace them. This guide explains both models, compares them side by side, and shows how to combine them on a large industrial project.
Temp-to-perm staffing in construction is an arrangement where a worker starts on the staffing agency's payroll as a temporary placement and converts to your payroll as a permanent employee after an agreed threshold of hours. It is also called temp-to-hire or conversion staffing.
While the worker is on assignment, the agency is the employer of record. At Cruitfly, that means the worker is a W2 Cruitfly employee, and Cruitfly carries the payroll, the reporting, the workers' compensation and the employment administration. You direct the work on site. When the conversion threshold is reached and you want to keep the person, they move to your payroll.
Temp-to-perm puts the worker on the agency's payroll first and yours later, while direct hire puts them on your payroll immediately, so the real difference is who carries the risk of a bad fit during the first weeks on the job.
| Factor | Temporary staffing | Temp-to-perm (conversion) | Direct hire |
|---|---|---|---|
| Who employs the worker | Staffing agency (W2), for the whole project | Staffing agency (W2) until conversion, then you | You, from day one |
| Who runs payroll, workers' comp and reporting | Agency | Agency until conversion | You |
| Trial on your site before commitment | Yes, for the project | Yes, built into the model | No |
| Typical length before the worker is yours | Not intended to convert, though clients may hire after the negotiated threshold | Cruitfly average around 480 regular hours (about twelve full-time weeks) | Immediate |
| Protection if it does not work out | Cruitfly replaces the worker, typically within 12 to 24 hours | Replacement while the worker is on Cruitfly's payroll | Cruitfly's 90-day guarantee, terms in writing before you sign |
| Best for | Project work, surges, shutdowns | Roles you want to keep but cannot afford to get wrong | Permanent roles you already know how to define and supervise |
The table hides one nuance. Temp-to-perm is not slower to start than direct hire. The worker is productive on your site from day one either way. What differs is when they become your employee, and who absorbs the cost if the fit is wrong in week three.
Direct hire staffing for the construction industry is a permanent placement: the staffing agency searches, screens and places a candidate, and that person becomes your employee on your payroll from their first day.
On Cruitfly's direct hire service, Cruitfly handles the search, the screening and the placement, and can supply copies of the certifications for anyone it puts forward. Direct hire placements carry a 90-day guarantee. Ask how it applies to your specific role before you sign, so the terms are in writing rather than assumed.
Direct hire works best when:
Choose temp-to-perm when the cost of a wrong hire is high and the only reliable test is watching the person work, which describes most skilled field trades in construction.
A résumé tells you where someone has worked. It does not tell you how they build scaffold in a tight enclosure, whether they keep a clean containment, or how they handle a foreman who changes the plan at 6 a.m. As Cruitfly puts it on its conversion staffing page, on skilled trades where a bad hire is expensive and slow to unwind, the trial period is usually worth more than the speed of hiring directly.
Temp-to-perm is usually the better call when:
Direct hire is usually the better call when the role is a permanent leadership or office position, when you have strong internal screening, or when the candidate will only move for a permanent offer.
There is no fixed calendar period for a temp-to-perm conversion at Cruitfly; on average, conversion happens at around 480 regular hours worked, which is roughly twelve full-time weeks.
The threshold is negotiated with each client, and clients may hire a worker once they have worked the agreed threshold hours. Three points are worth settling before the first worker starts:
Staff a large industrial project by keeping a small permanent core on direct hire, putting the roles you want to keep but have not yet proven on temp-to-perm, and covering the peak with temporary crews that demobilize when the work ends.
Industrial work rarely holds a flat headcount. A shutdown or turnaround compresses a large amount of labor into a short window with a hard end date. Cruitfly supplied 30 scaffold carpenters, plus scaffold helpers, for a partial power plant shutdown in Wyoming, and scaled a demolition and abatement project in Georgia to 86 workers over four months on a job that ran more than ten months. Neither headcount would make sense as permanent payroll.
Use the Core, Convert, Flex crew plan:
One real example of how the convert layer surfaces on its own: a Northeast insulation contractor started with three mechanical insulators and scaled to six in about two weeks, then asked to keep the crew long-term, potentially a year or more. That is the point at which a temporary crew becomes a conversion conversation.
Safety responsibility does not change with the model. OSHA states that staffing agencies and host employers are jointly responsible for a safe workplace for temporary workers, with the agency typically providing general training and the host employer providing site-specific training.
Look for an agency that employs the workers as W2 employees with workers' compensation, specializes in your trades, can show certifications on named workers before they travel, and will put its conversion threshold and direct hire guarantee in writing.
Four questions separate a real construction partner from a general labor agency:
Cruitfly's buyer's vetting guide covers the full checklist. For context on the model itself: 90% of Cruitfly's contracts are temporary or supplemental labor, and clients are free to hire workers after the negotiated threshold. Cruitfly's motto is "finding talent and building teams," and seeing its employees reach long-term employment with reputable companies is the goal.
Temp-to-perm and direct hire are not rivals. They answer different questions. Direct hire answers "I know exactly who I need, give me them permanently." Temp-to-perm answers "I need this role filled well, and I want proof before I commit." On a large industrial project you will usually want both, plus a temporary layer for the peak. Decide which roles sit in which layer before you place the first order, and get the conversion threshold and guarantee in writing.
Temp-to-hire (conversion staffing): An arrangement where a worker is placed through the agency, works on the agency's payroll for an agreed period, and can then be hired directly by the client.
Direct hire: A permanent placement made by the agency, where the worker goes onto the client's payroll from day one.
W2 employee: A worker employed directly by a company, with payroll taxes withheld. In staffing, a W2 worker is an employee of the staffing agency, which carries payroll taxes, unemployment insurance and workers' compensation.
Conversion threshold: The number of regular hours a worker must work on the agency's payroll before the client may hire them directly, negotiated per client.
Shutdown (turnaround): A planned period when an industrial facility stops production for maintenance, repair or replacement work, compressing a large amount of labor into a short window.

Temp-to-perm staffing in construction means a worker starts on the staffing agency's payroll as a temporary placement and converts to your payroll as a permanent employee once both sides are confident it is a fit. It is also called temp-to-hire or conversion staffing.
With temp-to-perm, the worker is the agency's W2 employee until conversion, so you see them work on your site before committing. With direct hire, the worker is your employee from day one. Temp-to-perm reduces the risk of a bad fit; direct hire gives you immediate ownership of the role.
There is no fixed calendar period, because it varies by client. On average, conversion happens at around 480 regular hours worked, which is roughly twelve full-time weeks. The threshold is agreed with each client.
Direct hire staffing is a permanent placement. The agency searches, screens and places the candidate, and the worker goes on your payroll from day one. Cruitfly's direct hire placements carry a 90-day guarantee, with the terms confirmed in writing before you sign.
The staffing agency does. At Cruitfly, the worker is a W2 Cruitfly employee, and Cruitfly carries the payroll, the reporting, the workers' compensation and the employment administration until conversion. You direct the work on site.
Keep a small permanent core on direct hire, put the field roles you want to keep but have not yet proven on temp-to-perm, and cover the peak with temporary crews that demobilize when the work ends. Stage the ramp rather than mobilizing everyone at once.
Look for an agency that specializes in your trades, employs its workers as W2 employees with workers' compensation, can show certifications, physicals and fit tests on named workers before they travel, and puts its conversion threshold and any guarantee in writing.
Both of you. OSHA states that staffing agencies and host employers are jointly responsible for temporary workers' safety. The agency typically provides general safety training and the host employer provides training specific to its site and hazards.
