Attachment 2 CPT Requirements.docx

This document outlines the Cone Penetration Test (CPT) equipment requirements for the Missouri Department of Transportation's FY26 Geotechnical Drill Rig procurement. The specifications detail a comprehensive equipment package including a Geoprobe 3135GT Tracked Geotechnical Drill Rig with a Geoprobe 105DP Drill Mast and GR10 Geotech Head Assembly. The required CPT system must feature a minimum cone capacity of 20 tons downforce and 30 tons pullback, with dual anchor points to provide symmetrical resistance against push forces. The equipment package includes a 10-ton digital seismic cone, friction reducers (both segmented and continuous configurations), 40 one-meter sounding rods, 45-meter EFCS Series sounding cable, and a 20-ton CPT rod auto clamp system. Additional requirements include an automatic seismic hammer, CPT data acquisition hardware and software capable of capturing seismic and dissipation data, auxiliary swing arm or swivel control area, an AC power unit inverter with multiple power outlets, and an engine design that allows easy accessibility for routine maintenance.

MoDOT has determined that Geoprobe Systems is the sole source capable of meeting all specified requirements, making this a one-time purchase through a single-source procurement. The specifications are restrictive by design, as Geoprobe Systems is identified as the only distributor meeting the comprehensive technical requirements outlined in the attachment. Interested parties or those seeking clarification regarding this solicitation should contact Ashten Lorts, the designated buyer, at ashten.lorts@modot.mo.gov.
