Case Study: Randle Construction achieves high accuracy, faster completion and major labor savings with Trimble GPS Grade Control and Site Positioning Systems

Randle Construction - Customer Case Study

Randle Construction, hired to put in foundations for about 610 privatized homes at Scott Air Force Base, faced a tight 20-month schedule and an unusually complex scope—35 foundation plans (72 layouts when flipped) across three phases. Traditional staking and grade-checking would have required heavy manpower and long setup times, threatening schedule and cost targets.

Randle turned to Trimble technology—installing a GCS900 GPS grade control system on a Cat 308C mini-excavator and using a Trimble SPS880 rover with a TSC2 controller for stakeout. The result: foundation digs that once took a full day now take about four hours, pad stakeout time fell from 3–3.5 hours to roughly 30–35 minutes, the need for an extra laborer in the trench was eliminated, and labor savings are expected to pay for the system before project completion while improving accuracy and future bidding competitiveness.
