Custom Home Construction (Electrical and Plumbing Rough In)

It’s a busy week at the site of the new home construction in Carrolltown, PA and this week some electrical and plumbing work began.

Electrical Rough In

The electricians are on-site and started the work on the electrical rough in.  Following the house plans, electrical wires are pulled and outlet and switch boxes are installed.

At this point, the house is still connected to temporary power.  The new meter box was attached to the house and a main disconnect was installed and inspected.  The new service wires will be run underground, through conduit, to the location of the new pole.  Penelec will be installing the new pole, transformer and underground feed wires this week.  The permanent new electric service can then be turned on to the house.

With our new home construction in Carrolltown, PA, the conduit was run under the driveway.  In this case, we used SCH80 conduit as it is a thicker and stronger pipe than SCH40.  From the pole, we are using 3” conduit for the electric into the house and 2” conduit for the phone and communication lines.

The wiring used throughout the house is a 12 gauge standard Romex wiring.  However, 14 gauge wire was used to connect the hard wired inter-connected smoke alarm system.

The electrical rough in needs to be completed and pass inspection prior to adding insulation or installing dry wall.

The plumbing rough in was also completed.  The plumber installed supply pipes that will deliver clean water into the house and to the plumbing fixtures like sinks, toilets, etc.  He also installed waste pipes that will drain the water and waste from the fixtures.  These pipes will later be

connected to the fixtures that you will see and use throughout the house.

Supply pipes can be iron, copper or numerous varieties of plastic.  Wilkins Contracting used PEX, or crosslinked polyethylene, pipe for this new home construction.  This pipe has several advantages over metal pipe or plastic pipe, like PVC.  PEX pipe is flexible and resistant to scale and chlorine so it won’t corrode or develop pinholes over time.  It also has a higher burst strength than copper pipe.

DWV, or Drain Waste Vent, pipe was also run.  This is a SCH40 pipe and is the system that removes sewage and greywater from the house.  It also regulates air pressure in the waste system pipes, which facilities flow.  Waste that is produced at fixtures, like toilets, sinks and showers, exit the fixture through a trap, which is a dipped section of pipe that always contains water.  The traps are necessary to prevent sewer gases from leaking into the house.  The traps are connected to waste lines which will take the waste gases to a soil stack, or soil vent pipe.  This vent pipe is attached and rises (usually inside a wall) to and out of the roof.  Waste is removed from the house through drains that take them to the sewage line or septic system.

As with the electrical rough in, the plumbing rough in needs to be completed and inspected prior to adding insulation or installing drywall.  The plumber will cap the system and pump compressed air into the pipes to assure there are no leaks.  If the air holds for 24 hours, there are no leaks and the inspection is complete.

A lot more work is happening this week.  The guys have started siding the house.  So, stay tuned for the next post and more photos!

Custom Home Construction (Foundation Walls)

100_0119We’re happy to say the weather has held up pretty well and the excavation went as planned.  Over the weekend the plumbing rough-in was completed and we are ready for foundation walls.

Tuesday morning was the day the foundation walls are delivered and put in place.  Wilkins Contracting used Superior Walls by Advanced Concrete for this project.  Their system is a process that begins with your custom design and ends with your pre-insulated basement.

Superior Walls by Advanced Concrete Systems are insulated precast concrete wall systems that are custom manufactured to each building’s specifications and have a minimum 5000+psi.  The product forms a concrete cavity wall panel with concrete studs reinforced with rebar and polypropylene fibers providing additional structural strength.  These walls are water-proof and energy efficient providing a built-in insulation with an R value of 21.  They include access holes that are built-in for wiring and can for plumbing as well so no additional framing is needed.

The walls are custom designed to virtually any architectural style to include window and door openings, beam pockets and brick ledges and are available in 4’, 8’2” and 10’ heights.  They are manufactured in a climate-controlled facility and delivered directly to the job site.  With the use of a crane and certified crews, the walls are installed in less than a day.

Now that the walls are in place, the basement floor will be poured and basement interior support walls will be built.
