Case Study: Seattle Tunnel Partners achieves rapid, automated document control and major time savings with ORACLE Aconex

Tunneling under Seattle Aconex energizes state route 99 project

Seattle Tunnel Partners (a joint venture of Dragados USA and Tutor Perini) used Oracle Aconex to manage the US$1.4B State Route 99 tunnel project under downtown Seattle. The project involved a 330‑person team across multiple organizations, more than 580 external vendor contacts, and complex cross‑company document flows; the original document control system lacked robust transmittal management, version control and search, creating risk of incomplete or hard‑to‑find information.

Aconex provided a single platform for document management, viewing, transmittals, bidding/tendering and correspondence, enabling secure exchanges, tracked RFP invitations/responses, easy public RFI search and a full audit trail. The team was operational in 3–4 weeks, automated control of 100,000+ documents, cut weekly report generation time by 75%, sped transmittal creation by 90% and uploads by 50%, and saved about 20 staff hours per week.
