On a private funded Clubhouse project out of the blue the MEP is asking for a Letter of Conformance on Vibration Control for HVAC and Electrical Equipment. The last time I saw this requirement on a private funded project was for Marriott Hotel work 10 years ago, and back than I never did understand the purpose of these Submittal Docs. Anyone care to enlighten me? |

I've seen lenders require that the design team submit letters of conformance attesting that the Work was performed according to CDs (which is it's own special form of heartburn and liability) but a letter from the Contractor to the engineer? New one on me. Is it just for that one aspect of work? It's not like you have seismic; hurricane but not seismic, right? Sounds like a copy and paste from an unrelated project. |

The Letter of Conformance was conceived as an administrative time-saver with certain building elements on projects in which there is a trusted relationship between the developer and the constructor. In short, the constructor promises to provide the specified product/system/subsystem without having to make the usual submittals to gain approval. Everything is documented when record documents are turned in. You can't use it with everything, especially items that have to do with life-safety. But you can do it with a lot of other things. |

Ken, David after I voiced my concern the Engineer deleted the Letter of Conformance language without explanation, a few minutes ago, i am willing to bet it was a cut and paste error. |

The contractors contract is with the Owner. Thus any letter of conformance to the MEP would be inappropriate. If the MEP engineer intended for the letter of conformance to be addressed to the Owner the Owner should have final say.
I would assume that the Owner contractor agreement already has an implied obligation for the contractor to comply with the requirements. Thus I see no advantage for the letter of conformance.
A major reason for submittals is to verify that the contractor interpreted the documents correctly. Even if you have confidence in the intention of the contractor there is still the possibility that the documents could be misinterpreted. Thus the submittals are still appropriate. |
