Dear Mr. Klein:
Re: Segmental Retaining Wall Observations, Lakeville Health, Lakeville, MN
As you requested, Vickery Engineering & Consulting, LLC (VEC) has performed visual observations of
the Veteran Pro segmental retaining wall at the referenced site. The site observations were performed
after construction. In addition, VEC has reviewed photographs of the wall construction and the testing
reports, prepared by American Engineering Testing (AET).
Background Information
VEC prepared final design and construction drawings for the retaining walls on this project. The plans
prepared are titled “Proposed Segmental Retaining Lakeville Medical Office, Dodd Boulevard and Cedar
Avenue South, Lakeville, Minnesota", and were dated 7/20/2022 (Revision 1). The project number for
the plans was VEC 22-194
Site Observations
After construction of the wall, VEC performed observations of the Veteran Pro retaining wall constructed
at the site. VEC observed the following:
1) The SRW units were placed in general accordance with the manufacturer’s specification.
2) The walls have positive batter, within 1 to 2 degrees of the design batter.
3) The tops of the walls were generally level.
4) Draintile outlets were observed extending through the wall face.
5) Geogrid was observed in several areas extending slightly through the wall face. The geogrid
was orientated in the correct direction.
It should be noted that our observations were performed after construction, and did not include testing of
the soil placement or soil compaction. Therefore, we cannot comment on the soil placement and soil
compaction or any of the construction methods used to build the wall. However, the testing reports from
AET indicate the foundation soils were suitable for support of the wall system and the compaction testing
indicates proper compaction was achieved in the backfill zone.
Conclusions
Based on our on-site observations, it is our opinion that the segmental retaining wall is performing in
general accordance with the plans prepared by VEC.
