council Report 92-255
LANDFILL PROJECT
CHANGE ORDER NO. 12
Proposed Action.
staff recommends adoption of the following motion: Move that
Council authorize Change Order No. 12 as it concerns the Seventh
Street South Landfill Gas Remediation Proiect.
overview
Staff approached Council in January of this year with what was
thought to be a final compensating change order concerning the
landfill project. An amount in excess of $30,000 was retained
until final inspection in the spring of 1992 as part of a
warranty on seeding operations. Upon inspection this spring it
was noted that special procedures would be required for turf
establishment on the slope overlooking Greenfield Apartments.
Those special procedures are encompassed in Change Order No. 12.
Primary Issues to Consider
o What are the costs?
The change order totals $7,437.50. This is payment for
additional regrading, seed, mulch, heavy duty silt fence,
and the use of wood fiber blanket.
o Staff recommendation:
The purpose of the change order work was to establish turf
in problem areas where vegetation would not take hold and
erosion of the Greenfield Apartment slope became critical.
Staff concurs with the consultant engineer that the net
increase in the contract price is justified and the change
order should be approved.
