Reviewed
At the client's request, ESNW rep was onsite to observe or test cut slopes, test pH of stormwater, footing
excavations and earthwork activities.
Cut Slopes
While onsite, rep observed south slopes of the cut slopes to be near vertical and covered in plastic sheeting. Rep
observed that the east slopes of the excavation were near a 0.75:1 (H:V) slope. Although over-steepened, slopes
are stable in current configuration and stable to work within. The contractor is responsible for providing all safety
measures in accordance with state and federal regulation. Rep observed that contractor had sloped the southeast
corner of the footing excavation to a 1 :1 (H:V).
Test pH of Stormwater
Rep took pH tests to determine the pH of stormwater. In the filled baker tanks rep observed 12.23 in a baker tank.
Rep observed that contractor added dry ice to lower the pH level. Rep observed that pH level was contained
onsite at a 6.5 pH.
Footings Excavations
Rep observed contractor use a medium sized excavator to excavate and the building footings. Rep recommended
and observed that contractor was over-excavating footings ~4" from designed footing grade. Rep observed
contractor backfill the over-excavation with a 3"-4" lift of 1 ¼" minus crushed rock for the footing subgrade to
increase stability during wall construction. Along the base of the footings, rep observed contractor install miradrain,
6" perforated pipe along the footings, and embed the pipe in a 12" lift of 2" wash rock.
ESNW rep will return to observe earthwork activities when requested by client �t-
