Free Mechanical Engineer Timesheet Template

Mechanical engineers working on a fee basis need to track time accurately across design, analysis, testing, and reporting activities, each of which involves different levels of expertise and complexity. A timesheet that links hours to specific systems or components helps clients understand where engineering effort is focused and supports monthly fee invoicing. It also provides essential data for project cost management and post-project profitability review.

Frequently asked questions

How should I describe engineering calculation work on a timesheet?

Reference the specific system, component, or standard being applied. 'Pressure drop calculations for cooling water circuit in accordance with EN 13480' is far more useful than 'calculations'. This level of detail also makes your timesheet a valuable technical record for the project.

Should I bill for time spent in design review meetings with the client's engineering team?

Yes. Design reviews are a critical part of the engineering process and require substantial preparation and active participation. Log the meeting time and any associated preparation or follow-up actions as separate entries.

How do I handle overtime or weekend work on a client project on my timesheet?

Log the hours on the day they were worked. If your contract includes a premium rate for overtime or weekend work, note this in the rate column or description. Clients on fixed-fee contracts may not pay a premium, but recording the hours still demonstrates the effort invested.
