Version 4.0 / November 2017 Building Component Catalogue with LOD levels MT HØJGAARD A/S - BUILDING COMPONENT CATALOGUE 2 Preface The building component catalogue with the level of development specification is targeted at MT Højgaard's projects for internal use and for our partners. The catalogue has been used on many of our own construction and infrastructure projects, but also by external parties. The motivation for this catalogue is that it is often unclear what geometry needs to be provided at a given milestone. The catalogue is inspired by Level of Development (LOD) definitions developed by the American Institute of Architects (AIA). The purpose of the catalogue is: · to help participants in construction projects define the geometry of models; · to help project participants clarify and specify geometry and property deliverables for a given milestone; · to help project participants and partners communicate the geometry of the individual building component for a given milestone; · to provide a reference for contracts relating to building models. The catalogue may, however, be used by and be an inspiration to the construction industry as long as the source is acknowledged. Copying or reproduction of this catalogue (or any part thereof) is not permitted without prior written agreement with MT Højgaard, vdc@mth.dk. This Building Component Catalogue is also published in Danish, Norwegian, German and Icelandic and will be updated on a regular basis. We welcome comments and suggestions for improvements at vdc@mth.dk. MT HØJGAARD A/S - BUILDING COMPONENT CATALOGUE 3 Reading instructions This Building Component Catalogue describes how MT Højgaard defines the levels (LODs, Levels of Development) for the geometry of selected building components. For each building component, the levels of development LOD 100 - 400 are specified and described using an illustration showing the recommended geometry and a descriptive text. LODs are ascending, where LOD 100 represents the lowest level and LOD 400 represents the highest level. The Building Component Catalogue is a reference book that can be used together with deliverable specifications for geometry (LOD) and properties (LOI), which are both prepared and tailored to fit each project. · The Model Progression Specification for geometry (LOD) specifies the geometry of building components in relation to e.g. conceptual design, preliminary design and main project milestones. · The Model Progression Specification for properties (LOI) specifies the properties of building components in relation to e.g. conceptual design, preliminary design and main project milestones.
