Our offrce has been retained by the general contractor (Michael Woelke of Mayan
Piering) to observe the repair and releveling 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 gdrage. The foundation system was previously
repaired and re-leveled in 2010. Our office has reviewed the cónstruction 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 ãUr"-.¿ the on-going
excavation and repairs onNovember 15, 2016 and November lg, 2016.
At this time Mayan Piering intends to convert the fixed pier system into a sysrem
of adjustable piers. The adjustable pier system will utilize extension stabilizer brací<ets
manufactured by Grip-Tite Manufacturing. Note that Grip_Tite provided the original
helical piers and brackets. Upon completion of the repairs and installation the nelw
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 byGrip-Tite Manufacturing.
Our office will. during excavation and construction, be providing specificationsand details as necessary for the repair of damaged concrete walìs. our office will beproviding foundation details to support the ügñtly loaded entry porch posts o¡ casr-in-place concrete piers and footings.
Attached find a copy of the 20r 0 foundation repair plan and a copy of a levet

Upon completion of the repairs our office will provide a final observation report
