CR 91-276 Landfill Project Change Orders 9/10December 11, 1991
Proposed Action.
Overview.
Council Report: 91 -276
LANDFILL PROJECT - CHANGE ORDER NOS. 9 & 10
Staff recommends adoption of the following motion: Move that
Council authorize Change Order Nos. 9 and 10 as they concern the
7th Street South Landfill Gas Remediation Project 90 -18.
Upon completion of the methane barrier unacceptable levels of
methane were discovered near the Westbrooke Patio Homes. Field
tests indicated the likelihood of the gas migrating over the
liner on the landfill side of the anchor trench just beneath the
densely compacted topsoil. Consultant engineers met with the
MPCA and the consensus was to perform corrective repositioning of
the liner. That work is contained in Change Order No. 9.
Because post - monitoring indicated the presence of methane between
the newly installed barrier and the Westbrooke property, several
additional monitoring wells needed to be installed near the
homes. The Westbrooke Association requested some means of
mitigating the visual impact of the wells and their protective
bollards. The planting of evergreen shrubs was the most
effective means of camouflaging.
Primary Issues to Consider.
o What are the costs?
Change Order No. 9 will cost an additional $26,746.40.
Change Order No 10 will cost an additional $2,622.00.
o What are the specifics of these change orders?
See the attached supplements from RCM and Associates
for description of change and justification.

This section will ensure that all contractors have either a state
or City license.
2) Owners of commercial or industrial buildings would not need
