<h1>IfcFM<a class="headerlink" href="#ifcfm" title="Link to this heading">¶</a></h1>
<p><strong>Facility managers</strong> (FM) need to know a lot of information about the building
in order to maintain the facility and its assets effectively. This includes
information about spaces, services, and key equipment, such as who to call when
things break, what the model number is, the warranty period, associated
certificates, what valve or circuit breaker must be shut off prior to
maintenance, and a punch list of periodic maintenance tasks.</p>
<p>Traditionally, this information is collected in numerous operations and
maintenance (O&amp;M) manuals. IFC can collect this information incrementally
throughout the design development, construction, and commissioning stages of a
project. IFC’s standardised and rich digital relationships can describe the
information that facility managers need. The most popular requirements
specification for IFC-based digital FM data is known as <strong>COBie 2.4</strong>.</p>
<p>Despite already requesting and receiving IFC deliverables, many clients still
request FM data in a spreadsheet format. Unfortunately, many of these
spreadsheet deliverables are not produced from IFC databases. This defeats the
purpose of BIM: asset data is no longer richly stored using international
standards and the BIM model may no longer be trusted.</p>
<p>IfcFM is a highly standards-compliant tool to convert FM data in IFC databases
to spreadsheets and other machine readable formats, such as ODS, XLSX, CSV,
Pandas, XML, and JSON. These formats may then be easily read, audited, or
imported into technologies that cannot work with IFC natively.</p>
