RE:	19^th & Barker Roundabout Project No. 56-CP12-901(C) Change Orders #2 and #3

Project Status.  During the completion of the 19^th & Barker Roundabout Project, two change orders have been developed to encompass various changes in project scope and/or fulfilled agreements made during property acquisition.  Change Order #2 involves a net increase of $21,640.  Change order #3 includes a net increase of $32,561.20.  (Change Order #1 was voided)  In addition, various bid items were adjusted during completion of the contract, with a net result being an increase of $26,304.93.

Project Details.  The following summarizes the details associated with the increased costs to the above referenced project.  Detailed information is attached.

Change Order #2:

1. Changes in project scope:

• Barker Avenue – construct 12 each mountable island noses, pavement markings, and delineator signs.
• Johnson Drive – install/remove concrete barriers.
• Forrest & Johnson Avenue – additional traffic control.
• Adjust sanitary sewer manhole
• Construct paver blockouts.

Change Order #3:

1.  Agreements with the adjacent property owners for the additional right-of-way and easements needed for utility relocates and to accommodate the improvements include, but are not limited to:

• 1900 Barker - construct 6” asphalt parking lot with curb and gutter.
• 1901 Barker - construct handicap ramp; construct new driveway large enough to allow a vehicle to turn around at the back of the house.
• 1846 Barker – remove an existing chain-link fence and driveway apron along Barker.

· 1847 Barker – remove and replace chain-link fence; construct retaining wall to replace raised flowerbed as part of the final grading.

• 309 E. 19^th – construct additional concrete driveway and a retaining wall to save a large oak tree.
1. As part of the waterline project, the plans called for the removal of the existing 4’ wide sidewalk and replace with a 6’ wide sidewalk.  This greatly affected the grades to six of the existing driveways along E. 19^th Street.  These driveways needed to be reconstructed and regarded. 
2. Other miscellaneous changes include, but not limited to, adjustments to traffic control to address the concerns of the local residents, special water meter lids requested by the Water Department, joint sealant and dowels for the 9” concrete pavement, etc.

     Additional bid item quantities:

1.  The quantities for various bid items were exceeded from those provided in the bid documents for the following project sections:

• Section 1 – 19^th & Barker Roundabout.
• Section 2 – 17^th & New Hampshire Roundabout.
• Section 3 – Waterline Improvements.

Project Funding.   The source of funding for the project include general obligation bonds and cash financing from the Water and Sewer fund for the portion associated with the waterline work.  The original contract with RD Johnson for the project included $293,315.10 of bonded work and $184,378.00 for waterline work.  With the additional work encompassed by Change Orders #2 and #3 and bid item quantities, the original project amount needs to be increased by:

o Change Order #2 (#21,640.00),

o Change Order #3 ($32,561.20)

o additional bid item quantities ($26,304.93)

Action Request.  Staff recommends City Commission approval of Change Order #2 and Change Order #3.  Additionally, staff is asking the City Commission to authorize the City Manager to increase the construction contract with RD Johnson in the total amount of $80,506.13.
