COMcheck Software

COMcheck automates the trade-off approach.

The COMcheck software is available in both a desktop and online version. The desktop version, simply called COMcheck, is available for both PC and Mac systems. The online version, COMcheck-Web, performs just like the desktop version but requires no download or installation.

What kind of reports does it produce?

In COMcheck, the user is given the option to generate any of four reports: Envelope Compliance Certificate, Lighting Compliance Certificate, Mechanical Compliance Certificate, and Mechanical Requirements Description. The certificates include information entered by the user on the components to be installed in the building, as well as a requirements section listing the additional basic requirements found in the code. The Mechanical Requirements Description gives a list of more detailed descriptions of the requirements in Section 4 of the Mechanical Compliance Certificate by component.

Note: Some states have their own versions of the Windows COMcheck software. These versions include specific example files and contact information. State specific versions are listed on the web page.

The COMcheck tools include an email feature which allows the user to email the compliance report to the local building department (provided that the local building department will accept email submittals).
