Conventional 2x
Framing:
This style of construction
utilizes 2x
studs, wood trusses or rafters, and wood floor joists. Wood
sheathing is used to stiffen the structure on the walls and the roof.
Most modern homes are constructed in this manner and most of
our
engineering expertise is in this method. |

Timber Frame /
Post
& Beam:
These related construction
methods, in
general, show off a heavy timber skeleton to the inside of a home.
Connections
rely on hardwood pegs in
traditional notched joinery for timber frames, or manufactured
steel
plates, brackets, etc. for post and beam. We have excellent
experience in these systems and have taught courses on the engineering
of these systems. |

Structural
Insulated Panels (SIPs):
Timber frames are usually covered
with rigid structural insulated
panels (or
SIPs)on
the walls and roof. These panels, though, are stiff enough to
be
used to form the walls and roof of homes by themselves without
significant internal framing. |

Insulated
Concrete Forms
(ICF):
This method uses foam
blocks that are
stacked on top of each other, reinforced with steel reinforcing bar
(rebar), and poured full of concrete. The foam functions as
the
concrete form and the reinforced concrete provides a very strong
structure. We've designed quite a few multi-story structures
using this system on all levels. |

Foundation
Systems:
We have a great deal of
expertise in
foundations covering a wide range of soil and loading conditions in a
variety of configurations, however, the vast majority of the
foundations have involved cast-in-place concrete. These
foundations normally
include retaining walls, pad footings, and strip or continuous footings. While
masonry
or CMU is normally adequate for perimeter walls, it is not typically
the system of choice
in the regions of the country where we've designed. |

Helical Piers:
These are screw-type
anchors that can be
installed in poor soils for new construction, or installed on the side
of or within existing foundations needing improvement. They
consist of one or more steel helices that are welded on the end of a
heavy steel shaft. This lead section is drilled into the
soil,
and extensions are added on until it reaches the proper depth.
We
recently finished a local foundation that used over one hundred of
these leads in poor soils.
