Bluebeam as BIM Substitute

The Building Information Model (BIM) process builds a project virtually to find problems before they happen in the field, and dramatically reduces time lost to conflicts of systems. While BIM is a very powerful and popular software, it requires a significant amount of time to properly coordinate before fabrication and installation. On smaller, more straight-forward interiors assignments, Bluebeam can be performed on an active project, takes much less time to execute than the traditional three-dimensional BIM process, and results in a smoother project with less risk for the client.

Challenge

As a tenant buildout began, it was discovered that architectural and MEP drawings did not indicate accurate existing ceiling conditions and were not coordinated with each other. There were multiple instances where existing overhead structural beams forced large-scale revisions to overhead MEP, as well as ceiling revisions.

Executive Action

Executive Construction used Bluebeam software to create combination of layered and overlaid drawings between overhead HVAC, electrical, fire protection, and RCP plans to display where large conflicts would occur. We sketched coordinated revisions on the two-dimensional PDF plans digitally—as a team in real-time—and distributed updates to the trades for fabrication and installation. These two-dimensional “paper BIM” coordination meetings eventually led to the creation of color-coded ceiling plans indicating where architectural ceiling conditions changed due to space constraints.

Results

Our client realized dramatic cost savings through improved installation efficiencies; elimination of potentially high-cost coordination to resolve conflicts; reduced re-work of installation; and reduced time lost to conflict resolution. Additionally, Executive Construction provided clients a highly detailed and accurate record of the as-built conditions that can be utilized for future expansions and modifications.
