San Francisco recently signed into law an ordinance making retrofitting of thousands of seismically unsafe buildings mandatory. This ordinance applies to wood-frame buildings built before 1978, which are at least three stories tall and have at least five residential units. These apartments are unsafe because an earthquake shakes the bottom floor that supports the weight of […]
When a basic 3D Revit® model is required, then during our survey we record the slab-to-slab elevations, as well as window/sill heights, door heights, plus exterior major architectural details including heights. We combine this information with interior and perimeter digital photos to create the model from the preliminary AutoCAD®drawings.
These models are typically described as Level of Detail (LOD) 200-300.
With all our projects, we take digital photos around the perimeter, as well as a few interior shots. However, when preparing 3D Revit models, we take many more interior and exterior photos. In combination with our laser-measured as-built drawings, the photos help our expert Revit team to create lifelike Revit models, without the added expense (and time) of having a 3D laser survey done.
Here’s an interesting article outlining the challenges of creating a BIM model on an existing building, for renovations.
The Building Owners and Managers Association International (BOMA) recently released: Office Buildings: Standard Methods of Measurement and Calculating Rentable Area (2010) (“BOMA 2010”). This publication is the latest in a succession of BOMA Standards, which have been widely used for the measurement of the rentable area of office premises since 1915.
The new publication contains many revisions and additions to the previous BOMA standard of 1996: Standard Method for Measuring Floor Area in Office Buildings (“BOMA 1996”). We are about to give you a glimpse into what’s new
