}µ"` •:Stt%i,qtural design of the footings was made by our office for
"CreE:.�ren" home which is to be constructed in the Thunderhird
Estates FiXth Subdivision, Fort Collins, Colorado. A design of the
footings has been made in accordance with criteria and recommenda-
tions as set forth in a soils report made of the area by this firm.
we recommend that the two-story and the one-story portions of
°the structure be supported by 8" x 12" continuous type footings.
Interior pads supporting the floor girder in the single -story
portion should be 1'-6" x P -6" x 10". It is further recommended
that the garage be supported by an 8-inch grade beam carried to at
least 30 inches below finished grade.
we`recommend that all foundation walls and grade beams he rein-
forced with two M5 bars both top and bottom. Pads supporting the
floor girder should have a4 bars at 12 inches on center both ways.
It is further recommended that slabs -on -grade be placed directly on
the undisturbed soil or compacted fill which has been slightly wetted
down prior to placing the concrete. All slabs should be reinfor:ed
with 6x6-10/10 mesh and should be structurally independent of all
bearing members.
It is important that all footings and grade beams be carried t,.
orikinal undisturbed soil. In no case should footings or grade beclms
be founded on fill material or loose soil. To verify this, we recom-
mend that a soils engineer inspect all excavations prior to placing
concrete. As per soils report, all backfill adjacent to foundation
should be mechanically tamped to 90% of standard proctor and no puddling
should be permitted. Additional precautions should be taken to prevent
wetting of foundation soils as discussed in the soils report. In our
opinion, full consideration has been given to the recommendations as'
`set forth in the soils and foundation investigation report.
