Description
The Oregon Department of Transportation seeks a qualified contractor to perform seismic cone‑penetration testing (SCPTu) with pore‑water‑pressure dissipation and shear‑wave‑velocity measurements at the Wikiup Junction site. The work supports a joint research project with OSU and PSU and must adhere to strict technical specifications, environmental BMPs, and a mandated no‑work winter shutdown. The contractor must supply all equipment, supplies, and personnel, deliver detailed reports and electronic data, and comply with federal Buy‑America, Cargo Preference, and FHWA Form 1273 requirements.
• Perform 3‑6 SCPTu soundings to ~250 ft depth (total 750‑1500 ft) with variable‑rate and pore‑pressure‑dissipation tests.
• Conduct shear‑wave‑velocity measurements at 1‑m intervals and provide hard‑copy and electronic reports within 14 days of each sounding.
• Follow a 5‑day‑on / 2‑day‑off schedule, observe a no‑work period (Nov 18 2026 – Mar 15 2027), and finish all work by 17 Nov 2027.
