Our Story

A Family Firm Built on Imperial Valley Roots.

Precision Engineering & Surveying, Inc. was founded in 1997 by Steve Preece — an Imperial Valley surveyor who had spent the prior 16 years in the field with Lyon Engineers and Pacific Land Surveying. From day one, the mission was simple: deliver honest, accurate, and reliable land surveying to the communities we call home.

Taylor Preece grew up in the Imperial Valley — Brawley born and raised. He worked summers and school breaks as a rodman starting in 2007, learning the land before he ever opened a textbook on it. He went on to earn a Bachelor of Science in Geomatics Engineering from California State University, Fresno in 2015, graduating Magna Cum Laude with a minor in Mathematics.

Taylor obtained his Professional Land Surveyor license in 2017 and has served as Survey Manager and Primary Land Surveyor since 2018. He is also a four-time elected President of the California Land Surveyors Association Desert Chapter (2020, 2021, 2023, 2025).

Together, the Precision team brings over 100 combined years of Imperial Valley experience — from county roads, canals, and farms to housing developments, industrial complexes, geothermal plants, solar farms, battery storage sites, and major utility corridors.
