Estimating the hours outsourcing BIM could free
A capacity estimate should describe how work changes inside the practice. Hours transferred to an external modeler are not automatically hours released: preparation, questions and acceptance still need attention. Use a simple comparison based on recent assignments to estimate the net effect, then check the result against what the team actually does after the first commission.
Measure a representative baseline
Choose several projects resembling the work you intend to outsource. Record time spent building the architectural base, organizing the file, resolving source questions and correcting modeling issues. Keep design development separate where possible. Note the condition of the original references and the included floors, because those factors affect the effort. Avoid using the fastest or most difficult project as the sole benchmark. A range based on comparable work is more useful than a precise-looking estimate built from an unusual example.
Estimate the remaining internal effort
Allow time to prepare current drawings, write the brief, answer questions and check the returned model. Include coordination with the provider and any work needed to fit the delivery into the practice's standards. The indicative net release is internal production effort avoided minus the new or remaining handoff effort. This is a planning method, not a guaranteed result. If the source package is incomplete or the review route is unclear, the estimate should reflect that uncertainty rather than assume an effortless handover.
Connect hours to actual use
Ask what the practice would do with the released attention. It might advance design decisions, handle a backlog or reduce pressure around an upcoming submission. Do not translate every estimated hour directly into revenue without evidence that suitable work and staff availability align. Consider when the hours become available, since scattered short periods may be less useful than a clear block. BIM12's capacity objective is something to assess for the practice, not a proven client outcome or an automatic fifty-percent improvement.
Build a defensible estimate
- Use comparable recent assignments to establish a baseline range, recording source condition and included floors instead of relying on one unusually easy or difficult example.
- Subtract preparation, questions and acceptance effort from internal production avoided, and keep uncertainty visible when references or review arrangements have not yet been tested.
- Identify how released time would actually be used, then compare the forecast with recorded effort after a first commission before extending the estimate across the practice.
Compare the estimate with recorded preparation, review and correction effort. Note which questions could be removed through a better template or standard. Update the forecast using the team's own result and repeat only when the workload changes materially. A credible capacity discussion uses transparent assumptions, a realistic range and a clear explanation of how the practice will use any time it actually releases.
General guidance: each project's scope is confirmed before commissioning.
