# [Construction Employee Time Tracking: The Complete Guide for GCs Managing Direct Employees and Subcontractors](https://blog.tasktag.com/construction-employee-time-tracking-new-2026)

 Written by [Olivia Reyes](https://blog.tasktag.com/author/olivia-reyes) | Oct 6, 2026, 12:46:27 AM

**A general contractor managing a mid-size commercial project has two distinct time tracking problems that most software treats as one.** Direct employees — the GC's own carpenters, laborers, and superintendents — need time tracked for payroll, overtime calculation, certified payroll compliance, and job cost reporting. Subcontractors — the MEP trades, specialty contractors, and material suppliers billing T&M — need time tracked for invoice verification, lien waiver alignment, and billing dispute prevention. Same job site. Same daily clock-in. Completely different downstream requirements.

**Treating both as "just track hours" produces records that serve neither purpose well.** Direct employee records processed through the wrong workflow miss certified payroll requirements. Subcontractor records accepted without GPS verification can't be defended when a T&M dispute surfaces at month four. The GC who understands the difference and sets up [construction employee time tracking](https://blog.tasktag.com/construction-time-tracking-software) correctly for both groups has the documentation to defend every labor decision from kickoff to closeout.

This guide covers the complete time tracking setup for GCs: what direct employee tracking requires, what subcontractor tracking requires, how GPS verification applies to both, and how to structure the conversation with subs before they mobilize.

## Part 1: Direct Employee Time Tracking

### What Direct Employee Time Tracking Must Capture

**Direct employees generate payroll obligations, workers' comp exposure, and EEOC record requirements.** The time record for a direct employee isn't just a billing document — it's a legal record that the Department of Labor can request, a workers' comp insurer can audit, and a plaintiff's attorney can subpoena. The standard for accuracy is correspondingly higher than for a sub's T&M invoice.

**Required data elements per clock event:**

- **Worker identity:** Name and employee ID — not "Worker A" or a foreman's memory
- **Date and day of week:** Required for daily overtime calculation in states with daily OT rules
- **Start time and end time:** With enough precision to calculate daily and weekly hours correctly
- **Location:** GPS coordinates confirming the worker was at the job site during those hours
- **Project:** Which job number the hours are being charged to
- **Classification (if prevailing wage):** Carpenter, laborer, equipment operator — the classification determines the required wage rate

**What happens without complete records:**

A Department of Labor audit on a prevailing wage project requests certified payroll records for an 8-week period. Records that are missing classifications, have reconstructed times rather than contemporaneous records, or show gaps in worker entries create compliance exposure. Penalties under Davis-Bacon range from contract termination to contractor debarment for willful violations.

A [construction employee time tracking app](https://blog.tasktag.com/construction-time-tracking-software) that captures all required elements at the moment of clock-in produces records that satisfy this audit — no reconstruction, no gaps, no disputes about contemporaneity.

### Direct Employee Time Tracking and Overtime

**Overtime calculation for construction direct employees has more variation than most contractors realize.** The federal FLSA baseline (1.5× over 40 hours per week) applies where no stricter state rule exists. Many states have stricter rules, and union agreements add additional thresholds.

**GC-specific overtime complications:**

**Multi-job weeks.** A worker who splits the week between Job 101 and Job 102 — 30 hours on one, 15 hours on the other — has worked 5 hours of overtime. The overtime is calculated on a blended rate of the two jobs' pay rates (if different), not just 1.5× the higher rate. [Construction employee time tracking](https://tasktag.com/features/gps-time-tracking/) that records job attribution at every clock-in makes this calculation automatic; paper timesheets make it a manual calculation that gets done wrong regularly.

**Union project requirements.** Collective bargaining agreements on union projects frequently specify overtime starts after 8 hours per day (not just 40 per week), double-time after 10 or 12 hours, and premium pay for shift work or holiday work. The time tracking system must be configured for the applicable agreement on each project.

**Prevailing wage shift differentials.** Some prevailing wage determinations include shift differentials — different wage rates for evening or overnight work. Time records that don't capture clock-in time precisely can't verify that the correct shift differential was applied.

### Certified Payroll for Direct Employees

**Certified payroll is the most documentation-intensive requirement in construction employee time tracking.** Weekly WH-347 reports (or state equivalents) must show each worker's name, Social Security Number (last 4 digits on public forms), work classification, hours by day, gross wages, deductions, and net wages — signed by an officer of the company under penalty of perjury.

**What** [**construction time keeping software**](https://blog.tasktag.com/construction-time-tracking-software) **must do for certified payroll:**

- Track classification per worker per project — the same person may be a carpenter on Job A and a laborer on Job B
- Record hours by day (not just weekly totals) — certified payroll requires a daily breakdown
- Export to WH-347 format or the state equivalent — not just a raw time export that someone has to manually format
- Support electronic submission for jurisdictions requiring LCPtracker, Elations, or similar systems

**Classification management:**  
Worker classification on prevailing wage projects isn't set once and forgotten. A worker who starts a project as a laborer and moves to form carpenter work mid-project changes classification — and the wage rate must change with it. GPS-verified time records tied to cost codes make this visible: the time record shows the worker switched from "02.100 Site Prep" (laborer) to "03.100 Concrete Formwork" (carpenter) on a specific date, supporting the classification change.

### GPS Verification for Direct Employees

**GPS verification for direct employees serves three functions:** it confirms workers are actually on site during the hours they're paid, it provides defensible documentation for workers' comp and prevailing wage audits, and it eliminates buddy punching at the source rather than discovering it later.

**Geofencing direct employee clock-ins:**

Set a geofence around each job site. Direct employees can only clock into that project when inside the boundary. The geofence:

- Prevents off-site clock-ins — workers who haven't arrived yet can't start accumulating paid hours
- Stops clock-ins from the job trailer on an adjacent lot, the parking structure, or the coffee shop across the street
- Creates a hard record of arrival time that can't be disputed — if the GPS shows a worker arrived at 7:58am, that's when they arrived

**Handling legitimate exceptions:**  
Workers whose job function requires them to be off-site (equipment pickup, material run, off-site fabrication shop) need the ability to clock in from off-site locations. Handle this with supervisor override — the superintendent manually approves off-site clock-ins with a notation. The exception is documented, not just allowed silently.

For [time tracking for construction workers](https://blog.tasktag.com/time-tracking-for-construction-workers) — the worker-level setup process including GPS permissions — the onboarding sequence ensures GPS is active before the first clock-in.

## Part 2: Subcontractor Time Tracking

### Why Subcontractor Time Tracking Is a Different Problem

**Subcontractor time tracking is a commercial problem, not a payroll problem.** The GC isn't processing the sub's payroll — the sub handles that themselves. What the GC needs is verification that the hours the sub bills were actually worked on the GC's project, by the sub's workers, at the times claimed.

Without verification, T&M billing is a trust transaction. The sub submits an invoice for 240 hours in March. The GC either trusts that number or disputes it — and without independent records, there's no basis for anything other than trust or conflict.

With GPS-verified subcontractor time tracking, the GC has independent records: who clocked in, from where, at what time, for how long. The 240-hour invoice either matches the GPS records or it doesn't. The conversation is specific: "Your invoice shows 240 hours but our records show 218 verified on-site hours — what accounts for the 22-hour difference?"

### Three Models for Subcontractor Time Tracking

**Model 1 — Trust (no tracking requirement):**  
GC accepts sub's time records as submitted. Sub provides T&M tickets or invoices with hours. GC reviews and pays without independent verification.

Use when: Fixed-price subcontracts only. Never on T&M scopes.

Risk: No recourse when invoice hours don't match actual site presence. Disputes escalate to "my records vs. your records" with no GPS evidence on either side.

**Model 2 — Sub uses their own GPS-verified system:**  
GC requires the sub to use a GPS-verified [contractor time tracking app](https://blog.tasktag.com/construction-time-tracking-software) and submit GPS-verified time records with every T&M invoice. GC reviews the sub's records and compares to their own site documentation.

Use when: T&M scopes where the GC has limited ability to require the sub's workers to use the GC's system. Common for specialty contractors with established systems.

Risk: The sub's GPS records are self-reported — the GC is trusting the sub's system rather than an independent record. Better than pure trust, but still one step removed.

**Model 3 — Sub workers use the GC's system:**  
Sub workers are added to the GC's [construction employee time tracking app](https://blog.tasktag.com/construction-time-tracking-software) for the duration of the project. Their clock-ins appear in the GC's dashboard alongside direct employees. GPS verification is identical for both groups.

Use when: Prevailing wage projects requiring certified payroll for all workers (not just direct employees). Large T&M scopes where billing accuracy is financially material. Subcontractors with a history of billing disputes.

This is the highest standard and provides the strongest protection. Sub workers may resist — "we don't use the GC's app." This is a contractual requirement negotiated before mobilization, not a request made after work has started.

### Putting Subcontractor Time Tracking in the Contract

**The time to establish subcontractor time tracking requirements is at contract execution, not when the first invoice arrives.** A sub who has already mobilized and has their own billing system in place will resist a new tracking requirement introduced mid-project. A sub who signed a contract with an explicit time tracking requirement has agreed to it before they started.

**Subcontract language to include:**

> Subcontractor shall maintain GPS-verified daily time records for all workers performing work under this subcontract. Time records shall be submitted with each invoice for time-and-material work. Records shall include the name of each worker, the date and times worked, and GPS-verified location at clock-in and clock-out. The GC reserves the right to dispute any T&M invoice where the submitted time records do not include GPS verification.

This language, reviewed during contract negotiation, sets the requirement clearly. For fixed-price subcontracts, the requirement is less critical but still valuable for documentation in dispute scenarios.

For subcontract negotiation context, see [how to negotiate a construction contract](https://claude.ai/blog/how-to-negotiate-a-construction-contract) and [construction bonds guide](https://claude.ai/blog/construction-bonds-guide) — both cover the documentation framework within which time records operate.

### What GCs Need from Subcontractor Time Records

**T&M invoice verification:**

When a sub submits a T&M invoice, the GC needs records that allow line-by-line verification:

| What to verify | What the record must show |
| --- | --- |
| Workers on site that day | Names of all workers with clock-in records for that date |
| Hours per worker | Clock-in and clock-out times for each worker |
| Location verification | GPS coordinates at clock-in — must match the project site |
| Work performed | Cost code or scope description for the hours billed |
| Overtime status | Whether any hours billed at OT or DT rates were actually worked |

**Lien waiver alignment:**

Subcontractor lien waivers are typically tied to invoiced and paid amounts. When sub time records feed the invoice, and the invoice drives the lien waiver amount, the entire chain is connected. Disputes about hours create disputes about lien waiver amounts — which affects the GC's ability to release clean title to the owner.

For how sub billing and lien exposure connect to the GC's financial position, see [construction retainage](https://claude.ai/blog/construction-retainage) and [construction cash flow management](https://claude.ai/blog/construction-cash-flow-management).

**Prevailing wage compliance for sub workers:**

On public projects with prevailing wage requirements, the obligation extends to subcontractors. The GC is responsible for certifying payroll compliance for all tiers of the project — not just direct employees. Sub workers' time records must support certified payroll documentation at the sub level, with the GC responsible for ensuring those records exist and are accurate.

### Managing Sub Time Tracking in Practice: The Pre-Construction Meeting

**Sub time tracking requirements that aren't communicated before mobilization don't get implemented.** The pre-construction meeting with each subcontractor is the right moment — before the sub's foreman has established their own routine, before any invoices have been submitted, and while the contractual requirement is fresh.

**Pre-construction agenda items for time tracking:**

1. **Requirement confirmed:** Show the sub the contract language. Confirm they understand GPS-verified time records are required for T&M work.
2. **System established:** Is the sub using their own GPS-verified system, or will their workers use the GC's app? Confirm the answer and set it up before the first day.
3. **Submission process:** How and when are sub time records submitted? With each invoice, weekly, or daily? Who at the sub's company is responsible for submitting?
4. **Invoice and record format:** What does a compliant T&M invoice from this sub look like? Walk through a sample if needed.
5. **Dispute process:** If the GC's records and the sub's records disagree, what's the process for resolution? Establish this before the first disagreement, not during it.

## Setting Up the GC's System for Both Groups

**The** [**construction employee time tracking app**](https://blog.tasktag.com/construction-time-tracking-software) **setup for a GC managing both direct employees and subs requires a clear organizational structure.** Workers from different companies on the same job site need to be distinguishable in the time records while being trackable through the same GPS verification system.

**Project structure:**

- One project per job number in the time tracking system
- All workers on the project — direct employees and sub workers in Model 3 — assigned to that project
- Cost codes loaded for the full project scope
- Geofence set for the physical site boundary

**Worker organization:**

- Direct employees: flagged as GC employees, linked to GC payroll
- Sub workers (Model 3): flagged as sub workers, linked to their employer's sub record
- Dashboard view: can filter by employment type — show only GC workers, only Sub A workers, or all workers

**Supervisor access:**

- GC superintendents: see all workers on the project
- Sub foremen (if given supervisor access): see only their own company's workers
- PM: cross-project view of all GC direct employees across all active jobs

**GPS settings:**

- Geofence applies identically to both groups — no worker can clock in from outside the site boundary without supervisor override
- GPS records stored for both groups in the same system — complete site attendance record

## Real-Time Dashboard: What the GC Sees

**At 7:30am on a typical project day, the GC superintendent's** [**construction time keeping software**](https://tasktag.com/features/gps-time-tracking/) **dashboard shows:**

- GC direct employees: 12 of 14 clocked in from GPS coordinates matching the site boundary
- Mechanical sub workers: 4 of 5 clocked in, 1 missing
- Electrical sub workers: 6 of 6 clocked in
- Framing sub workers: 8 of 8 clocked in, 1 GPS anomaly flagged (clocked in from the street adjacent to the site, not inside the building)

**Actions from the dashboard:**

- Two missing GC workers: call the foreman — are they running late or reassigned?
- Missing mechanical sub worker: notify the sub's foreman — expected on site today
- GPS anomaly on framing: ask the framing foreman to have the worker re-clock from inside the building perimeter

These are 7:30am conversations with specific information. Without real-time [construction employee time tracking](https://blog.tasktag.com/construction-time-tracking-software), they're Friday conversations during payroll reconciliation, after the week has already been paid and documented.

## Weekly Time Tracking Review: Direct Employees and Subs

**End-of-week review process covers both groups but produces different outputs:**

**Direct employees → Payroll export:**

- Review all hours by worker, verify against overtime thresholds
- Confirm cost code attribution matches work plan
- Export to payroll system in correct format
- Certified payroll export generated for prevailing wage projects
- Payroll admin reviews and approves

**Subcontractors (Model 2 or 3) → Invoice verification:**

- Pull GPS time records for each sub by week
- Compare against sub's submitted T&M invoice
- Flag any discrepancies — hours claimed vs. GPS-verified hours on site
- Approve the portion that matches verified records; dispute the remainder in writing

**Combined output for job cost:**

- All hours — direct and sub — attributed to cost codes
- Job cost report updated with actual labor by scope
- Budget vs. actual comparison current through last Friday
- PM reviews before the following Monday

## Common GC Time Tracking Mistakes

**Tracking direct employees but not subcontractors**

The biggest gap. Sub T&M billing is often the largest unverified cost on a project. "We track our own guys" and accept sub invoices on trust leaves 30–40% of project labor cost unverified.

**No GPS verification for sub workers**

Accepting sub time records without GPS verification means accepting the sub's word. On a project with $500,000 in T&M subcontract work, a 5% billing error is $25,000 — real money that GPS verification would catch.

**Not establishing requirements before mobilization**

A sub whose foreman has been texting time records for three weeks will fight any change. The contract language and the pre-construction meeting establish requirements before work begins.

**Missing classification tracking on prevailing wage projects**

Tracking hours but not worker classifications on prevailing wage projects creates certified payroll records that are incomplete. Incomplete certified payroll is a compliance violation with the same consequences as no certified payroll.

**Separate systems for direct employees and subs**

Two time tracking systems on one job site produces two sets of records that can't be compared. When a dispute arises about which workers were on site on a specific day, records in incompatible systems require manual comparison and are more easily disputed.
