The attached resolution provides for the acceptance of the public improvement
construction contract for the Althauser St. Retaining Wall Repair Project.
BACKGROUND
This Althauser St. Retaining Wall Repair Project involved the reconstruction of an existing
concrete/stone retaining wall near 902 Althauser Street. The project included a new 80
cubic yard reinforced concrete retaining wall with a textured face, HMA street pavement
and PCC driveway pavement. There was a small wood fence to be removed and replaced
in the yard below the retaining wall. All disturbed turf was seeded.
DISCUSSION
The Althauser St. Retaining Wall Repair Project was completed by Tschiggfrie Excavating
Co. in the final contract amount of $181,329.39 which is a 25.9% increase from the
original contract amount of $144,004.50. The reason for the increase is due to the need
to replace a fire hydrant and repair the water main in the project limits. Additionally, there
were additional costs required for the new retaining wall tied into the existing adjacent
stone wall.
RECOMMENDATION
I recommend that the City Council accept the Public Improvements and authorized the
payment of $181,329.39 to Tschiggfrie Excavating Co. for the Althauser St. Retaining
Wall Repair Project.
