One of the amazing things
about American homes is that the huge majority of them are built using
completely standardized building practices. One reason for this
consistency is a set of uniform building codes that apply across the
country. Another reason is cost -- the techniques used to build homes
produce reliable housing quickly at a low cost (relatively speaking). If
you ever watch any house being built, you will find that it goes through
the following steps:
Grading and site preparation
Foundation construction
Framing
Installation of windows and doors
Roofing
Siding
Rough electrical
Rough plumbing
Rough HVAC
Insulation
Drywall
Underlayment
Trim
Painting
Finish electrical
Bathroom and kitchen counters and cabinets
Finish plumbing
Carpet and flooring
Finish HVAC
Hookup to water main, or well drilling
Hookup to sewer or installation of a septic system
Punch list
Many of these steps are performed by independent crews known as
subcontractors. For example, the framing is generally done by one
subcontractor specializing in framing, while the roofing is done by a
completely different subcontractor specializing in roofing. Each
subcontractor is an independent business. All of the subcontractors are
coordinated by a contractor who oversees the job and is responsible for
completing the house on time and on budget.
We will walk through these
different stages so that you can see what is involved, understand all
the steps and learn about the different materials used in the
construction process. We will use a typical three-bedroom home as our
example.
