Case Study: Tutor Perini Building Corp achieves faster document control and major time savings with Oracle Aconex

Tunneling under Seattle Aconex energizes state route 99 project

Seattle Tunnel Partners (STP), a joint venture of Dragados USA and Tutor Perini, used Oracle Aconex on the $1.4 billion State Route 99 tunnel under downtown Seattle. The 2‑mile, 58‑foot‑diameter project involved a 330‑person multidisciplinary team plus more than 580 vendor contacts, and struggled with cross‑company coordination, limited transmittal/version control and poor search—creating a risk of incomplete or hard‑to‑find project information.

Aconex delivered a single platform for document management, bidding, correspondence and audit‑ready vendor communications, enabling complex document exchanges, RFP tracking and easy public RFI search. The team was up and running in 3–4 weeks, automated control of 100,000+ documents, cut weekly report time by 75%, created transmittals 90% faster, reduced upload time by 50% and saved about 20 staff hours per week.
