Emergency Sewer Repair at Bighorn Drive - PW419
REQUESTED ACTION
Approve quote with Parrott Contracting, Inc.
BACKGROUND
EarlIer this year it was brought to the attention of the City that portions of the sanitary
sewer pipe in the Bighorn Drive utility easement adjacent to a drainage ditch has become
unearthed. At several locations along the alignment of the sanitary sewer pipe, the storm
water ditch has meandered over the pipe and eroded the soil cover over the pipe. The
City utility crew televised the pipe and it was found to be in good condition. No
infiltration of storm sewer water was found and the pipe does not appear to have heaved.
However, if the sanitary sewer pipe is left in its present condition, the sewer pipe could
heave and create a sewer spill or a backup could occur, or storm water could enter the
sewer pipe causing significant infiltration into the City sewer system which could
overwhelm the down stream lift station.
Staff does not have the expertise or equipment to fix the problem in-house, but has
solIcited quotes for the repair. The repairs involve reshaping the storm water ditch to its
original alignment, placing fill back over the sanitary sewer pipe, and placing rip rap to
help stabilized the ditch embankment. The storm sewer ditch at this time of the year has
little flow so access and workability of the site will be easier. A few small sapling trees
in the dramage easement will need to be removed for construction and access purposes.
Staff has contacted the adjacent property owners on the project and has informed them
about the potential improvement project. Access to the site will be from Carver Beach
Road through the trail easement.
Two quotes were received as follows:
Parrott Contracting, Inc.
Kusske Construction Company, Inc.
$30,855.00
$31,285.00
Parrott Contracting, Inc was low by $430.00. Parrott Contracting, Inc works with the
City on most watermain breaks and their work has been acceptable.
Funding is proposed from the emergency sewer repair budget.
Staff recommends awarding the contract to Parrott Contractmg, Inc.
