CULVERT RE-WORKThe re-work of this under-penstock culvert was necessary due to previous installation not meeting specifications. To
meet this project’s critical design specs, the correct inlet/outlet elevation had to be exact to maintain slope ratios.
This allowed proper development of bowl sizes, culvert to penstock seperation, pipe coverage and finished road width.
Using a laser level from a 4 meter off-set stake, the crucial elevations for inlet/outlet were met within 1cm of specs
after the final check from our surveyor. With the water controlled, I was able to excavate and achieve ideal density
on our finished culvert invert grade. The bottom of the 48” HDPE (backfilled in the final pictures) had the required
20cm separation from the top of culvert. Finished pipe coverage called for 1.5 meters of structural fill, which after
our final spread of fine blast rock, fit the design perfectly.

LOT PREP
This lot prep began with the careful clearing, grubbing
and stripping between two existing residential lots. To
achieve proper bottom of footing elevations, 45 loads
of rock had to be hammered and removed from site.
Water and sani services were also hammered to depth
and installed. Once final grade for the footing base was
met and tested, the excavation was complete. This lot
prep surpassed clients expectations in both speed and
efficiency, as well as customer service.
