Project No. 19-7-180
Monolithic Structural Slab Foundation Alternative, Proposed Residence, Lot 9,
Sun Meadow Estates, North Meadow Drive, Garfield County, Colorado
As requested, we are providing additional recommendations for design of a frost protected
monolithic foundation alternative for support of the proposed residence at the subject site. We
previously conducted a subsoil study for design of foundations at the site and presented our
findings in a report dated April 2, 2019, Project No. 19-7-180.
The proposed construction is the same as described in the previous report. Based on our
findings, the residence can be supported by a frost protected, structural slab foundation with
thickened edges designed for an allowable bearing pressure of 1,500 psf. The subgrade should
be evaluated for bearing conditions and the need for sub -excavation and placement of compacted
structural fill prior to placing foundation forms. Other recommendations presented in our
previous report which are applicable should also be observed.
If you have any questions or need further assistance, please call our office.
Sincerely,
Kumar & Associates, Inc.
