What is BIM? Building Information Modeling (BIM) is a digital, three plus dimensional representation of the physical and functional characteristics of a building. A BIM is a shared knowledge resource for information about a building forming a reliable basis for decisions during its life-cycle.

What is LOD? Level of development (LOD) is a set of specifications that gives professionals in the AEC industry the power to document, articulate and specify the content of BIM effectively and clearly. Serving as an industry standard, LOD defines the development stages of different systems in BIM.


AIA first formally published LOD Definitions in 2008 (AIA Document E201) centered around the design development process. BIMForum, in cooperation with AIA, has expanded the standard and generalized it to apply to the detail level of modeling, detaching it from a progression of design stages and making it suitable for specifying levels of detail to be captured when modeling existing conditions. BIMForum has been publishing and updating their LOD Specifications since 2011 with 2023 being the latest version.

As-Built Drawing

Many projects we work on need some as-built drawing work when an asset or portfolio of properties is acquired and record drawings are out of date or in need of updates. Basic floor plan as-built drawings are a great solution when you just need basic information for property management. Solid Tech is quick and accurate in measuring plans from scratch, or auditing existing plans and correcting errors and infilling missing tenant or building improvements.

Solid Tech Brings over 35 years of experience in architectural drafting existing building documentation.
