SUBJECT:
Council Consideration for the Acceptance of Public Improvements for the Alley Pavement Management System 2016 Project, Installed by Powder River Construction, Inc., in the Amount of $337,971.48 (1% Project).
BACKGROUND:
The Alley Pavement Management System 2016 Project (16EN13) included rebuilding all or portions of three (3) alleys. The project included approximately 2,100 SY of 6.5" and 7" PCC Pavement, 2,500 SF of miscellaneous sidewalk, driveway, valley gutter and fillet, and removal and replacement of 403 LF of 8" sanitary sewer main and 12 services.

The Cloud Peak Alley portion was rebuilding two asphalt pavement sections of the alley running from 5th to 6th Street between Gillette Avenue and Kendrick Avenue (approximately 200 LF) and replacement with concrete pavement and inspecting three (3) saddle wye connections for the sanitary sewer services.

The Courthouse Alley included rebuilding West 5th Street running east from Warren Avenue to the end of  the alley running from West 5th Street to 4th Street between Gillette Avenue and Warren Avenue. The combined length of the alley and 5th Street is approximately 520 LF. This portion of the Project also included sidewalk, driveway, and curb and gutter adjacent to the Parking Garage. Also, eleven (11) new bollards were installed on the West side of the Courthouse. These items were requested by the County. The County paid for the components they requested of the project since they were outside the scope of the City's original scope of work.

The 3rd Street Alley included rebuilding the alley running from 3rd Street to 4th Street between 4-J Road and Rockpile Blvd (approximately 340 LF) including removing and replacing the existing 8" sanitary sewer line. After the project began, and additional 70 LF of 8" sanitary sewer was added to the project south of 4th Street.

The contract established 60 working days to Substantial Completion, and 70 working days for Final Completion. There were 9 days added by change order for additional work in the project. The project was finished on August 10, 2016, which was within the allotted contract time.
ACTUAL COST VS. BUDGET:
The original contract with Powder River Construction, Inc. was in the amount of $334,596.25. There were five (5) change orders. Change Order #1 was to clarify the duties of the City managing the project and Bruce Engineering Inc. limited duties. Change Order #2 was to add the 70 LF south of 4th Street at a cost of $15,953.25 and an additional 5 working days. Change Order #3 was to add an additional 80 LF of curb and gutter on 5th Street as requested by the Campbell County Public Works Department and an additional 2 working days for the additional work. Change Order #4 was for additional work incurred when and area of slurry 8'x10' by 8' deep was found on the north end of the Cloud Peak Alley just south of 5th Street and an additional 2 working days for the additional work. Change Order #5 was to decrease the contract amount by $12,578.02 for quantities not installed in the project. These five change orders resulted in a net increase of $3,375.23, resulting in a final contract price of $337,971.48.

Funding for this project was allocated from the 1% Optional Tax Account 201-10-05-419-40-44331.
