Case Study: OHL Construction Canada achieves 96% faster design review cycles with Oracle Aconex

OHL-FCC accelerates design review cycles by 96%

OHL‑FCC, the joint venture working on the Toronto‑York Spadina Subway Extension (the OHL‑FCC Toronto Subway Extension, a US$359M segment of the C$2.6B program), faced extreme technical and logistical challenges: tunnel boring in wet sand under high pressure, a project team of 350 people from 252 organizations, and a paper‑heavy process with more than 200,000 documents and nine separate contract books requiring multiple hard copies.

By deploying Oracle Aconex as a single online collaboration platform, OHL‑FCC centralized document control, tracked communications and revisions, and created a full audit trail. The result: design review cycles accelerated 96% (from 3–4 days to 3–4 hours), bidding time cut by 80% (30 days to 5–7), third‑party communications down ~88–90% (25–28 days to 3), change‑management time reduced 50–66% (21 to 5–7 days), paper savings of 8,900 kg and $13,350 in admin costs, and annual indirect savings of $396,000 with half the project coordinators.
