FROM: BRUNO RUMBELOW, CITY MANAGER
MEETING DATE: JULY 17, 2018
SUBJECT: APPROVAL OF CHANGE ORDER NO. 1 — INFLOW AND INFILTRATION
PHASE 3 PROJECT AND APPROPRIATION ORDINANCE
RECOMMENDATION: City Council to consider Change Order No. 1 to the Inflow and Infiltration
Phase 3 Project with Excel 4 Construction, LLC for sanitary sewer inflow
and infiltration improvements and an ordinance appropriating the funds.
FUNDING SOURCE: Upon approval, funds in the amount of $33,000 will be available in the
Utility Enterprise Capital Fund Account 201-48940-534-009-0044SW.
BACKGROUND: There is an existing six-inch sanitary sewer line running in the backyards
of homes along the north side of College Street between Church and
Scribner Streets. This existing sewer line was not built within a dedicated
easement several decades ago and bisects three relatively deep lots. The
existing home at 504 West College Street wished to add on to their home
over the existing sanitary sewer.
This change order will authorize Excel 4 Construction to oversee the
revision of the sewer lateral lines for three homes along College Street
(404, 416 and 504 West College Street) so that the public line in the rear
yards may be taken out of public service. These three homes will be tied
into the new sewer line in College Street with their own private sewer tap.
In 2011, the City installed a sanitary sewer within College Street with
stubbed out services in anticipation these houses would be tied into the
College Street sewer line and the line in the rear yard would be
abandoned. This will remove the encumbrance caused by the sewer line
in their rear yards. Change Order No. 1 is $23,000 with an overall project
contingency of $10,000 for a total cost of $33,000.
On January 16, 2018, Grapevine City Council approved the construction
contract with Excel 4 Construction, LLC in the amount of $1,488,847 for
the Inflow and Infiltration Phase 3 Project. Funds in that amount were
appropriated at that time. Construction is on schedule for completion by
December 3, 2018.
Staff recommends approval.
