Crane Day Wednesday!

The much anticipated crane date has finally been set for Wednesday, March 19th between 7am and noon. Please tune in to see the cranes lift up the frame and roof that the we have been assembling for the last week and a half.

Rumor has it there may be a small gathering of people Wednesday morning to watch. If you are unable to be with us in person, please tune in and watch on the blog.

Jump In!

This site was set up for the use of the PPUMC community. Please feel free to start your own posts, ask questions, talk smack or just say hi.

Tomorrow will be a big day in the erection of the building. Tune in from the blog or stop by and check in at the site to watch some heavy lifting.

Word of the Week #3

MEP

MEP stands for mechanical, electrical and process piping (most think it stands for plumbing, but that is only part of it). As the building structure begins to take shape, start to think of your project as if it were a person. You will hopefully see the skeletal system (structural steel) begin to appear over the next week, followed by the skin (exterior sheeting, plaster, windows, doors). During the prior month, maybe you noticed a great deal of piping and conduit disappear under the building pad. Those were the underground portions of the MEP system. As the skin goes on the building, the MEP subcontractors will tie into the underground lines and begin to "rough-in" (rough-in is the portion of the MEP system hidden above the ceiling, in the walls or under the floor). The MEP finish is the trim- switches, light fixtures, toilets, sinks, etc. The trim is the easy part of the project. The rough-in takes the most time and is ultimately the most critical part of install due to the consequences of a mistake. If a light bulb needs changing, not a big deal, right? If the switch is flipped and no power hits the fixture, finding the problem could require opening walls, ceilings or concrete slabs (sometimes all of the above). Extra care must be taken to minimize mistakes during rough-in.

Think of the M (mechanical) as the heart and lungs of a building. The piping of a mechanical system is used to heat and cool a building and the ducting in a building inhales fresh air and exhales the return air, regulating both temperature and humidity in your building.

The E (electrical) operates much like the central nervous system, sending commands through a network of nerves (wires) and signaling the major systems to operate as required. The electrical system in your building also provides most of the power for those systems to function as opposed to the hydraulic system that the human body relies on. Shutting off the power to a building leaves you with an expensive tent. Power and data systems range in cost from 20% up to 45% of modern construction project budgets.

The P (process piping) includes the plumbing system which closely correlates to the digestive system in a human and the fire sprinkler system. Any good analogies for the fire sprinkler system? Maybe sweat glands? Get too hot and the sprinkler release fluids to cool the temperature? Feel free to chime in. Rumor has it we have at least one medical doctor in the audience, maybe he would be willing to work out the sprinkler/body correlation.
