Dear Ryan,
Zlehler Engineering, LLC has reviewed the progress of conebLxtion for the maned p *d, The foliowinp
are our comments.
New Observatlons:
Reviewed the helical piles and W& To the !zest of my knowledge and belief, the helical PIN appeared to
be installed in conformance with the structural mitigation plan.
Site grading around the perimeter of the house did not appear to be modified.
• Vegetation around the perimeter of the horse did not appear to be moctfied.
• Exterior slabs did not appeev to be modified.
Vofatlle solls:
We believe that moisture around the foundation elements must be controlled for the useful ft of the Wilding. Time
has shown that Colorado soils can be unstable and struchm can experience damaging movements due to
expanding and shrinking soils, primerily when moisture changes occur. Maintaining went soil molt"
contents around all foundation elanneft is crucial to mfrdm=V tad undation movements, Even with properly
foundation systems these volatile sods can st it exert excessive pressures causing damage
to the residence. If the Owner would Idle fuller insight about the on -sae sow condones and preventative
measures, a Geotedmical Engineer should be hired.
oeotocivdeW Con Wdwauons
It is posabile that the piers may consolidate if the bowing location becomes wetted. Because of this, penochc
surveys of the supported structures should be conducted to assure pmjed success. The Owner should be
responsible for annual surveys cotfying project success. We would suggest that a baseline survey be oorduted
immedilaiely. The Owner should report all findings and reports to the Structural Engineer. If vertical movement of
the piers is discovered, the piers should be re -pressured. A Geotschincel Engineer should be present to obsemre
the re-press1 ring. A final report should be provided by the Geotechricai Engineer after observing the re -pressuring.
DWCWirrrer:
In as much as the site review of an existing structure for the purpose of observing the structural cond'dOns requires
that certain assumptions be made regarding existing conditions, and because some of these assumptions may not
be verffmde without exile k1h additional stuns or more" or destroying oBmrvise adegLmte or serviceable portions
of the bu8olng, the Client agrees that, except for negligence on the part of the Engineer, the client w3 hold
harmless, indemnify and defend the Engineer from and agaamt any and GO claims arising out of the professionel
services we have provided.
Sincerely,
Michael S. Z-ehler, P.E.
