ACE San Gabriel Trench
San Gabriel, California, United States
For the $500 million ACE San Gabriel Trench project in San Gabriel, Calif., HDR
provided a concrete U-structure with double track to ensure uninterrupted
and safe rail operations. The primary challenges were the density of existing
urban infrastructure, limitations of the right of way, freight rail track geometry
constraints, the multidiscipline nature of the project, construction sequencing,
and the maintenance of uninterrupted rail operations.
HDR used InRoads, InRail (now Bentley Rail Track), MicroStation, and
Project Wise to integrate a skilled design team distributed over multiple
locations, facilitate rapid deployment of the project team, and accelerate
information sharing and communications across project teams. Interactive file
exchange and compatibility of various file formats provided compatibility with
third-party source files such as DWG.

Victoria Station Upgrade Project
London, United Kingdom
The Victoria Station Upgrade Project is a $925 million improvement and
expansion of one of London Underground’s busiest stations. Used by more than
80 million passengers each year, the station has been experiencing passenger
numbers that have outstripped its capacity, causing severe congestion and
delays. A significant construction challenge is the station’s central London
location, in the midst of historic buildings, other important structures, and
numerous utilities.
BIM ensured a fully coordinated, multidisciplined design that will reduce
ambiguity during construction. Project Wise ensured that all design team
members were developing their designs in tandem using a single source. The
contractor has committed to maintain BIM through the construction phase
so the client will ultimately receive an asset that can be used for lifecycle
maintenance and operational modeling.
