AGENDA TITLE: Adopt Resolution Approving Contract Change Orders No. 1, No. 2 and No. 3 and
Appropriating Additional Funds for Lodi Grape Bowl All -Weather Surface Project
($134,400)
MEETING DATE: August 4,2010
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt a resolution approving Contract Change Orders No. 1, No. 2 and
No. 3 and appropriating additional funds for the Lodi Grape Bowl
All -Weather Surface Project in the amount of $134,400.
BACKGROUND INFORMATION: City Council at its meeting of April 7, 2010 awarded a contract to
Western Engineering Contractors, Inc., in the amount of $592,675 for
field preparation and awarded a contract to Fieldturf USA, Inc., for the
purchase and installation of the field. The appropriation for the
Western Engineering Contractors' contract included $87,325 for contingencies. This work involved the
preparation of the Grape Bowl, the clearing and grubbing of the existing field and the installation of new
irrigation and storm drain systems.
Three change orders are presented herein for the Council's consideration. Contract Change Order No. 1
addresses increased costs incurred by Western Engineering Contractors related to changed conditions at
the project site. Western Engineering Contractors encountered five locations where excessive moisture
in the subgrade required over -excavating and recompactingthe soil. The contractor also encountered
unsuitable sand material while trenching in the existing parking lot area. The cost for this additional work
is $21,800. The contractorwas also required to modify an existing 8 -inch water main and relocate and
rewire electrical conduits, the locations of which were previously unknown and conflicted with the new
construction. The cost for this additional work is $32,997.10.
Contract Change Order No. 1 addresses the above-mentioned items, as well as the cost to provide
maintenance equipmentto groom the all-weather field ($8,200) and a cost to modify the quick coupler
installation ($2,400.30). Estimates are also included in Contract Change Order No.1 to reconnect the
new irrigation system to the existing irrigation system and to furnish and install signage around the
perimeter of the field. The total cost for Contract Change Order No. 1 is $69,497.40 and is within the
contingency funds appropriatedfor the project.
Contract Change Order No. 2 addresses exit requirements of the Building Code and access
requirements of the Americans with DisabilitiesAct (ADA). The existing stairs from the bleacher areas to
the field level did not meet current ADA standards and needed to be replaced with new steps. In
addition, disabled parking stalls need to be added with concrete walkways to provide an ADA -compliant
path of travel to both north and south bleacher areas. ADA -compliant ramps will also be installed to
connect the new walkways with the bleachers. The locations of these improvements are noted on
Exhibit A. This condition was a design oversight and should have been included in the original contract.

This was discovered by the Building Division while discussing access requirements associated with
Contract Change Order No. 3, as presented below. Staff estimates the cost for the parking area,
walkways, ramps and steps to be $94,600.
Contract Change Order No. 3 covers optional additional work recommended by staff and approval is
requested of the Council. Staff recommends the installation of an 11-footwide concrete walkway along
the north and south sides of the field, from the edge of the field to the existing retaining wall fronting the
stands. The concrete walkways provide better access to the field, require less maintenancethan the
planned compacted aggregate base (ExhibitA), protectthe field and storm drain system from fouling by
dirt tracked from the perimeter and provide better access for equipment to the west end of the
Grape Bowl for maintenance and future development. These improvements complement the all-weather
use of the Grape Bowl and support the future addition of ADA seating at the foot of the stands (see
attached Exhibit B). Also recommended is a railing along the eastern side of the field designed to
prevent vehicles from driving onto the new field. Western Engineering Contractors provided a quote to
the City of $48,612 for this concrete walkway and an estimate of $9,000 for the protective railing work.
This is a reasonable investment considering the reduced maintenance, improved access, and field
protection afforded by these improvements, The locations of these improvements are noted on Exhibit A.

Staff is recommending the appropriation of $134,400 from the Park Impact Fees Fund to cover these
three contract change order costs and other costs associated with this project. The current Parks Impact
Fees Fund balance is $2,500,000 and by approving these change orders, the balance will be $2,365,600.
FISCAL IMPACT: Reduced maintenance cost of the areas surrounding the all-weather
surface and reduced exposure to ADA access claims at the Grape Bowl
facility. Use of impact fees will reduce funds available for future parks.
FUNDING AVAILABLE: Requested Appropriation:
Parks Impact Mitigation Fees (1217005): $134,400
