Note -- obsolete historical guidance. DRS marks this information "not current" and states that Announcement (AN) 94(3) obsoleted the ruling.

Plain-English summary

Hydrology and hydraulics, highway design, environmental engineering, soils engineering, and site engineering were not taxable. Presenting the work to government agencies for approvals, preparing cost estimates, project management, construction supervision, and project inspection were also not taxable.

Boundary surveys, topographic surveys, and construction staking were taxable land-surveying services.

What this means for you

The historical ruling separated the engineering and project-support work from surveying and staking. AN 94(3) later obsoleted the guidance.
