Attn: Andy Schwaller
Re: Residence at 54 Silver Mountain Drive,
Ironbridge Suddivision, Garfield County, CO.
Our office has been retained by the general contractor (Michael Woelke of Mayan
Piering) to observe the repair and re -leveling of the foundation of the noted residence.
The foundation is a crawl space system with continuous cast -in-place concrete perimeter
foundation walls and an attached three car garage. The foundation system was previously
repaired and re -leveled in 2010. Our office has reviewed the construction documents for
that repair (Dated June 24, 2010 by Fuhrmann Engineering Services, LLC). Those
construction documents specified the installation of a total of twenty-nine (29) helical
piers with 3.112" diameter steel pipe shafts. Brian Kurtz, P.E. has observed the on-going
excavation and repairs on November 15, 2016 and November 18, 2016.
At this time Mayan Piering intends to convert the fixed pier system into a system
of adjustable piers. The adjustable pier system will utilize extension stabilizer brackets
manufactured by Grip-Tite Manufacturing. Note that Grip-Tite provided the original
helical piers and brackets. Upon completion of the repairs and installation the new
stabilizer brackets, the piers will, in the future, be adjustable from the surface: additional
excavation and structural modification will not be necessary to adjust the piers. Note that
the existing piers will be extended through the use of compression couplings supplied by
Grip-Tite Manufacturing.
Our office will, during excavation and construction, be providing specifications
and details as necessary for the repair of damaged concrete walls Our office will be
providing foundation details to support the lightly loaded entry porch posts on cast -in-
place concrete piers and footings_
Attached find a copy of the 2010 foundation repair plan and a copy of a level
survey of the subject residence performed in April 2016. As of April 2016 the residence
displayed a maximum differential settlement of 8"
Upon completion of the repairs our office will provide a final observation report
