Pinnacle Engineering took our 38-lot subdivision from preliminary grading through county sign-off. Their drainage report and utility profiles matched what planning asked for — we cleared second review without a redesign cycle.

On our four-story apartment stack, their MEP sheets coordinated shaft routing with the structural grid before we poured. Title 24 documentation was complete the first time the city inspector walked the job.

Their stormwater report and BMP sizing for our arterial widening held up under public works review. Comment responses were technical, not boilerplate — that kept our council hearing on schedule.

We needed a hillside wood-frame addition stamped for snow and seismic loads. Pinnacle Engineering issued foundation and lateral calcs our architect could drop straight into the permit set — building department picked it up in one pass.
