The final results of tests and observations indiiate thiit the filled ground hos been compacted
to the densities OS prescribed in the project specifications.
- The imported fill moterial placed within the upper 2 feet on portions of Lok 39 to 42,
inclusiv~e, and Lots 44 tp 57, inclusive, contained clayey type soils in the expansive cate-
gory with respect to voIumetric‘.chonge with change in moisture content,. It is therefore - recommended that all footings ond slobs placed on these lots be specially designed so that
no structural domoge will occur due to the movements of these expansive soils.
- Respectfully sibmitted,
