Change Order Item No. 1.04: Refuse Enclosure Changes
A. Reason for Change
i. Wall Extension: Given the emergency declaration, the 95% plan set was bid while routing through City plan check, assuming minor revisions during construction. Within the bid documents, a two-foot opening was depicted between the refuse enclosure roof and CMU wall. Due to the current fire code, the final permitted plan set required the west CMU wall (within five feet of combustible walls ) be extended to the roof to prevent potential fire spread.
ii. Screens: To deter illegal dumping, the City requested screening to be added at the remaining two-foot opening between the roof and CMU wall. iii. Light Fixture: To provide adequate lighting within the enclosure , an additional solar light was requested to match the light installed at the exterior.

5 B. Description of Change
i. Wall Extension: The 19-foot 4-inch west wall of the trash enclosure was heightened by two feet to the roof, and the footing was increased by approximately 4 cubic yards of concrete, inclusive of all additional wall reinforcement, hardware, and paint. This refuse enclosure wall extension work totaled $9,277.00.
ii. Screens: Approximately 94 square feet (2’x47’) of galvanized carbon steel screening was installed and painted with a protective coating for marine and trash enclosure environments. This refuse enclosure screen work totaled $12,052.80. iii. Light Fixture: A motion activated 5000 lumen solar light was supplied and installed within the enclosure. This refuse enclosure light fixture totaled $477.30.
C. Change in Contract Cost
Add $21,807.10
D. Change in Completion Date
Add 5 working days
Change Order Item No. 1.05: Electric Vehicle Charging Station (EVCS) Conduit
A. Reason for Change
Given the emergency declaration, the 95% plan set was bid while routing through City plan check, assuming minor revisions during construction. Building and Safety required the design and implementation of four EV charging stations for current use and 10 EV capable spaces for future development . The estimated timeline for Southern California Edison to create an electrical design for the four EV charging stations work extended beyond that of the emergency construction, therefore the bid set ultimately required the install of 2-inch minimum PVC conduit from the proposed metered pedestal location to the EV charger locations. Conduit from the electrical point of connection (POC) to the metered pedestal location as well as supply and install of EV chargers were to be provided by others under future separate contract. During construction, it was determined to be efficient to install typical EVCS sized conduit in an effort t o not have to excavate again after completion of Edison’s electrical design.
B. Description of Change
Approximately 50 linear feet of 3-inch schedule 40 PVC conduit with a polypropylene pull cord of 2000lbs tensile strength in each conduit was installed 42 inches deep from the proposed metered pedestal location to the existing electrical point of connection. Schedule 80 conduit was stubbed up and capped 2’ above grade at the proposed pedestal location for connection. Conduit was capped and terminated at the southside property line to avoid cutting into Center Place. Costs were agreed between the City and contractor not to exceed $9,000.
C. Change in Contract Cost
Add $9,000
D. Change in Completion Date
Add 2 working days

6 Change Order Item No. 1.06: Existing Lot 3 CMU Wall Improvements
A. Reason for Change
i. Existing CMU Wall Leveling and Cap: During the emergency demolition , the City requested the west CMU wall of the existing structure to be sawcut and shortened to four feet as a safe guard between the adjacent properties due to the changes in elevation and to not disturb adjacent foundation. During demolition a clean cut of the aged blocks was not capable of being maintained throughout the entire s pan, and inner reinforcement became exposed , causing the potential for future deterioration, littering, and safety issues.
ii. CMU Wall Paint and Aluminum Angle: The aged CMU wall was discolored and patched in multiple l ocations. Along Center Place, pedestrians were inserting trash (i.e., rubber gloves, cigarette butts, crushed aluminum cans, etc.) into a 2.5” crevice between the existing Lot 3 CMU wall and the adjacent private property building.
B. Description of Change
i. Existing CMU Wall Leveling and Cap: The existing Lot 3 CMU wall was heightened to a minimum of 42-inches from adjacent finish grade and capped. The CMU wall leveling and cap work totaled $2,809.00.
ii. CMU Wall Paint and Aluminum Angle: Approximately 400 SF of CMU wall was painted. Roughly 45 linear feet of 3”x4” aluminum angle was installed at the top of the existing CMU wall closing the gap along 1140 Highland Avenue. The CMU wall paint and aluminum angle work totaled $6,060.98.
C. Change in Contract Cost
Add $ 8,869.98
D. Change in Completion Date
Add 2 working days
Change Order Item No. 1.07: Sidewalk Improvements
A. Reason for Change
i. Radius Curb Replacement: The existing curb and gutter at the northeast corner of the site did not match the elevations needed for the new compliant ADA curb ramp and adjacent planter.
ii. Planter Curb: The new ADA compliant si dewalk elevations at 1131 N Morningside Drive created a sloped planter area. There was a need to retain the planter soil and provide a safe level area adjacent to the walk path.
iii. Detectable Warning Surface: The detectable warning surface located on the northwestern curb ramp of the driveway approach along 12th Street was installed, but due to the apron’s slope elevations in the field, the City’s ADA coordinator recommended the warning surface be extended across the apron to the curb for full length pedestrian detection.
B. Description of Change
i. Radius Curb: The contractor removed and replaced 40 linear feet of existing curb and gutter with the required 18 inches of asphalt slot patch removal and replacement. The radius curb work totaled $5,321.50.

7 iv. Planter Curb: A 7-foot long 1-foot 4-inch high curb was installed, 12 linear feet of the curb and adjacent step were painted yellow for safety precaution against trip hazard, and 20 CF of topsoil was compacted to 2” below adjacent finish surface within the planter area. The planter curb work totaled $4,551.82.
ii. Detectable Warning Surface: A 3’x5’ surface-mounted detectable warning surface was supplied and installed. The detectable warning surface was not to exceed $2,000, and matches recent bid costs.
C. Change in Contract Cost:
Add $11,873.32
D. Change in Completion Date:
Add 2 working days
Change Order Item No. 1.08: Signage and Striping
A. Reason for Change
Given the emergency declaration, the 95% plan set was bid while routing through City plan check, assuming minor revisions during construction. The lot’s layout was slightly revised during the bid to address requirements for ADA space and adjacent aisle dimensions which ultimately created the need for compact spaces to maximize parking space quantity.
Metered parking space number s and signage were then finalized and added to the lot’s layout for application at the pay kiosk. The bid plans required that most parking lot signage be installed on the city-furnished solar parking lot lights, unless otherwise noted. Because of the manufacturer’s import delays due to implemented tariffs and unknown hold timelines by customs, the lights were not capable of being assembled and installed for approximately 6 weeks beyond their originally estimated arrival. To continue with opening the parking lot for public use at the earliest convenience, the City Traffic Engineer approved installing temporary posts for parking lot signage until the solar lights were installed.
B. Description of Change
Additional signage and striping work included:
• Quantity (Qty) 6 – “compact” stencils
• Qty 66 – 12-inch painted stall numbers
• Qty 6 – Compact sign and posts
• Qty 1 – 2-3 Hour Metered Parking Sign And Post
• Qty 13 – 2-3 Hour Metered Parking Sign on Existing Post • Add 2 Permit Parking Only Signs And Posts
• 1 stop sign and post (installation only)
C. Change in Contract Cost:
Add $ 19,587.00
D. Change in Completion Date:
Add 2 working days

8 Change Order Item No. 1.09: Landscape irrigation and controller changes
A. Reason for Change
The layout of the lot and adjacent landscaping maximizes the amount of spaces possible for parking. With this, the solar irrigation controller specified in the plans was sized at approximately 25 x 38 x 19 inches. Given the 5’ planter area, there was concern about the strong box being hit by vehicle overhang. Park maintenance recommended the smaller DIG LEIT equipment be utilized instead and at a location less likely to be damaged by drivers.
Given the specified controller was programmed specifically for Lot 3, the supplier states that it is not non-refundable. Park maintenance has accepted the non-refundable controller for programming and use at a future location. The existing water meter box was broken and in need of replacement.
B. Description of Change
The contractor furnished and installed a DIG LEIT Controller Model X, RainBird compatible DIG LEMA 1700S Micropower DC Solenoids, and DIG LEMA 30-926 Rainbird 1700s/1600HE Adapter (PEB/PESB). A 17x30x12 inch composite box was purchased and installed.
C. Change in Contract Cost
Add $4,969.26
D. Change in Completion Date

Change Order Item No. 1.10: Additional Solar Parking Lot Lights
A. Reason for Change
The quantity listed in the bid documents for bid item 16, Assemble and Install City-Furnished Solar Parking Lot Lights, was written in error as six (6) lights. The true amount was ten (10) lights per the bid plan set drawings.
B. Description of Change
Given the mobilization and economies of scale, the contractor decreased the unit cost and performed the work required to assemble and install the four additional city-furnished solar parking lot lights.
C. Change in Contract Cost
Add $8,959
D. Change in Completion Date
Add 1 days
Change Order Item No. 1.11: Solar Light Tower Rental
A. Reason for Change
The solar parking lot lights manufacturer, Greenshine, experienced import and delivery delays due to implemented tariffs and unknown timelines by customs, and the lights were not capable of being assembled and installed. To continue with opening the parking lot for use at the earliest convenience, a temporary solar light tower was proposed to provide a
