LANDFILL PROJECT - CHANGE ORDER NUMBERS 5 & 6
Proposed Action.
Staff recommends adoption of the following motion: Move that Council
authorize Change Order Numbers 5 & 6 as they concern the 7th Street S.
Landfill Gas Remediation, Project 90 -18.
overview.
Integral to the landfill project was trench dewatering and a measuring
system to gauge amount of discharge into the sanitary sewer system.
Now that the project is complete, this discharge flow rate measuring
system has had to be dismantled and the disturbed pavement and a
driveway in the area fully restored. The installation of the original
system was required by the MWCC and incorporated in Change Order No.
3.
The MPCA requested the placement of additional top soil material over
the landfill on an area of the site north of the refuse disposal area
and also requested seeding, mulch, and disc anchoring of the same
area. This is in keeping with the MPCA's requirements for
establishment of vegetation on all areas overlying refuse.
Primary Issues,to Consider.
o What are the costs?
Change Order No. 5 will cost an additional $1,870.00.
Change Order No. 6 will cost an additional $22,693.05.
o What are the specifics of these change orders?
See the attached supplements from RCM and Associates for
description of change and justification.
