Name That Penetration

The standard contract for a commercial construction project is between the Owner and the Architect.  Nowhere in that contract is there a relationship between the Owner and Mechanical Engineer.  What this does, in a sense, is make the Architect the face for everything design.  When the Owner sees how gigantic his roof-top unit is after it is installed, he doesn't call up the Mechanical Engineer, he calls the Architect. 

Therefore, it is the responsibility of the Architect to know enough about Mechanical, Electrical and Plumbing systems to identify those items that have impact visually and architecturally on the design...in a perfect world.  In reality, this rarely occurs and the design is tweaked up until the last minute and often into the construction phase and pretty soon the Architect is clueless.  We are not without weapons in this fight.  The wonderful specifications and general notes contain language such as, "submit shop drawings showing exact locations..." and, "notify Architect of discrepancies..." and my favorite, "contractor to coordinate." 

Principle on my list of pet peeves, are penetrations through the exterior envelope.  These are not only spots for moisture and air infiltration, but they have a direct impact on the aesthetics.  Without a solid understanding of MEP systems and what elements need to penetrate the envelope and where they occur and which code they follow; you end up with a swiss cheese facade. 

So to illustrate the difficulties in coordinating all of the various mechanical trades responsible for affecting the design, it is time to play:
