Project Overview

IET completed a 20-boring geotechnical program for HVJ Associates North TX under work order WO-DGT-18-10245.2. Borings ranged from a 10 ft piezometer-type boring (P1) to several 50 ft borings, for a total of 645 feet.

Of that footage, 455 feet were advanced by wet rotary drilling and sampling and 190 feet by NQ rock coring. Every borehole was plugged and abandoned on completion.

Scope of Work

  • Boring locations B3, B4, B5, B9, B10, B13, B15, B17, B21, B23, B26, B28, B29, B31, B33, B34 and P1 at depths from 10 to 50 ft
  • Wet rotary drilling and sampling, 0–50 ft (455 ft)
  • NQ rock coring (190 ft)
  • Borehole plugging and abandonment (645 ft)
  • Single round-trip mobilization
