Hourly Workforce Time Tracking & Scheduling3 min readUpdated September 2026

Time Tracking for Field Techs Who Aren't in the Office

Engineering firms should track field technician hours by job site, not just by time, because site hours are often billed to a specific project. Salaried engineers work in the office, while hourly technicians, surveyors and CAD drafters are tied to particular sites and project budgets, so where they clocked in matters almost as much as when.

Buddy Punch and Deputy both handle location-aware hourly tracking, but the choice usually comes down to whether the firm's bigger problem is verifying site time accurately or coordinating which tech goes to which site each week.

Why field hours carry more weight than office hours here

An hourly field technician's time is frequently the direct input into a project's labor budget, tracked against a specific job number the way a general contractor tracks a subcontractor's hours. A discrepancy in a technician's reported hours doesn't just affect their paycheck, it can throw off a project's cost tracking against the client contract, which makes accurate, verifiable site time a bigger deal here than at a typical office-based professional services firm.

Buddy Punch's fit: geofenced punches per job site

Buddy Punch's GPS geofencing can restrict a clock-in to a defined radius around a specific job site address, which confirms a technician was actually where their timesheet says they were. That matters for firms billing time-and-materials contracts where the client can request documentation of when and where field work happened, and it removes the ambiguity of a technician logging hours from memory at the end of a long site day.

Deputy's fit: assigning techs to sites across a project pipeline

A firm running several active projects at once needs to know which technician is assigned where this week and next, and Deputy's shift-based scheduling handles that assignment problem more directly than a punch-clock tool built mainly around verification. If a drafter needs to rotate between two active projects depending on deadline pressure, Deputy makes reassigning that coverage more visible to the whole team than a manager privately reshuffling a spreadsheet.

Splitting a single day across two job sites

Field work often means a technician visits more than one site in a day, a morning survey at one project and an afternoon inspection at another. Requiring a punch out and back in at each site, rather than one long shift manually split later, keeps each project's labor cost accurate instead of relying on the technician's memory of roughly how the day divided up. This is a small operational habit that has an outsized effect on project cost accuracy.

What happens when a job site has no cell coverage

Remote or rural project sites, common in civil and structural work, sometimes have no reliable signal for a GPS-based punch to sync in real time. Confirm directly with whichever vendor is chosen whether punches are cached locally and synced once a connection returns, and build a manual correction process for the rare case where a sync fails entirely, since a field crew working in a coverage dead zone shouldn't lose accurate time tracking just because the terrain doesn't cooperate.

Connecting field hours to project cost reporting

Neither Buddy Punch nor Deputy natively rolls hours up into a project's cost-to-budget report, that link usually has to go through whatever project-management or accounting system the firm already uses for job costing. Treat the time-tracking tool as the accurate source of when and where someone worked, and the project-costing system as the place where those hours become a budget number a project manager actually reviews against the contract.

Deciding whether to start with verification or scheduling

Firms new to formal time tracking sometimes try to solve both problems, verified hours and coordinated scheduling, in a single rollout, which tends to slow the whole effort down while the team gets trained on everything at once. A cleaner path is picking whichever problem has actually cost the firm money recently. If a client has questioned billed field hours, start with the verification piece and get Buddy Punch running well before layering on more scheduling complexity. If projects have stalled because no one knew which technician was free, start with Deputy's assignment view instead.

Either way, involve project managers early, since they're the ones who'll notice immediately whether the new hours match what they've historically seen for similar site work, and their early feedback is a better signal than waiting for a full quarter of data to accumulate before finding out the rollout missed something obvious to anyone running an active project.

Use these questions to decide where to start:

  • Ask whether a client has recently questioned billed field hours, and if so, start with verified, geofenced punches per job site.
  • Ask whether coordinating technicians across a project pipeline has been the costlier problem, and if so, start with scheduling.
  • Avoid rolling out verification and scheduling together, since training the team on everything at once tends to slow the whole effort down.
  • Test how the app behaves at a remote site without coverage before a broad rollout, rather than assuming punches will sync later.
Executive Capability Standard

What Good Looks Like

Good time tracking for an engineering firm's field staff means every job-site hour is verified and tied to the right project, technicians moving between sites in a day get an accurate split, and project managers can trust the labor hours behind their cost reports.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Pull recent project cost reports and check how often field labor hours had to be estimated or corrected after the fact.
2. Do Manually:Have field technicians log site visits and hours on a paper timesheet reviewed weekly by a project manager.
3. Delegate:Put a project manager in charge of the weekly field assignment schedule and reviewing hours before they roll into cost reports.
4. Automate:Move to a geofenced clock-in tool like Buddy Punch or a shift-assignment tool like Deputy so site hours are captured as they happen.
5. Buy:Connect verified field hours directly to project cost reporting so budgets are built from recorded time rather than end-of-week estimates.

Frequently Asked Questions

Can a technician's job-site hours feed directly into project cost reporting?

Not natively in most cases. Both tools capture accurate, verified hours, but rolling those hours up against a specific project's budget usually requires exporting into whatever job-costing or project-management system the firm already uses for that purpose.

What happens if a technician can't get a GPS lock at a remote job site?

Confirm with the vendor whether the app caches a punch locally and syncs once a connection returns. For firms regularly working rural or remote sites, this is worth testing directly before rolling the tool out broadly, rather than assuming it works from the product description alone.

How do we handle a drafter who splits time between office design work and field site visits?

Track hours by location or project tag rather than relying on a single daily total, so office design time and field site time can be reported separately if the client contract bills them at different rates.
