Subject: Change Order No. 18
Change Order No. 18 provides for:
The grouting of Gabion Wall baskets.
Supporting Information:
The double tier (multi -row) Gabion Wall section has a row of baskets approximately 130 linear feet in length
that rests a foot below the finish surface. The finish surface will be used as a future multi -use access path for
City emergency vehicles, City maintenance trucks and pedestrian traffic. This original detail would not allow
for the subgrade and finish surface to meet compaction requirements which can cause cracking and other
surface failures throughout time. To meet compaction requirements and minimize City maintenance of the
multi -use path, pouring slurry in the Gabion baskets was determined to be a proper solution to support the
base and surface of the access path.
