Case Study: Wm. Winkler achieves 25% faster curb and gutter work and site positioning with Trimble machine control and SPS930 Universal Total Station

Wm. Winkler Speeds Curb and Gutter Work and Site Positioning by 25% with Trimble Machine Control and Universal Total Station

Wm. Winkler is a 100-year-old concrete and civil contractor based near Spokane, Washington, specializing in site concrete, pavements, curb and gutter, and civil works. Facing challenges of slow survey-dependent workflows, tight traffic windows, and unreliable GPS under heavy canopy, the company wanted to integrate accurate 3D site positioning and machine control so crews could perform stakeout, measurements and paving without waiting on surveyors.

Wm. Winkler deployed Trimble solutions — PCS900 paving, GCS900 grade control, SPS930 Universal Total Station, SCS900 site software and Business Center - HCE for 3D modeling — across its fleet and crews. The result: about a 25% reduction in survey, paving and earthwork time (typical 20‑day tasks cut to ~15 days), two weeks saved on an eight‑mile curb-and-gutter job, elimination of stringing and survey waits, faster pours and more accurate quantity tracking, all with lower labor and site costs.
