An Ordinance approving Change Order No. 4 to the agreement with Radmacher Brothers Excavating Company, Inc. for Project No. 422-C, 3^rd Street Improvements from Pryor Road to Murray Road, an increase of $344,354.66 for a revised agreement amount of $5,831,449.56, and authorizing the City Manager to execute the same.  (PWC 2-14-22)

Body

Issue/Request:

An Ordinance approving Change Order No. 4 to the agreement with Radmacher Brothers Excavating Company, Inc. for Project No. 422-C, 3^rd Street Improvements from Pryor Road to Murray Road, an increase of $344,354.66 for a revised agreement amount of $5,831,449.56, and authorizing the City Manager to execute the same.

Key Issues:

•                     Several contract quantities are being adjusted to match the actual quantities constructed.

•                     Integral retaining walls were added to flatten the final slopes of yards at several locations.

•                     Additional stamped concrete was added to eliminate small areas of grass.

•                     Several water meters were relocated during construction to accommodate relocated utilities.

Proposed Committee Motion:

I move to recommend to City Council approval of an Ordinance approving Change Order No. 4 to the agreement with Radmacher Brothers Excavating Company, Inc. for Project No. 422-C, 3^rd Street Improvements from Pryor Road to Murray Road, an increase of $344,354.66 for a revised agreement amount of $5,831,449.56, and authorizing the City Manager to execute the same.

Background:

This Change Order will adjust all contract quantities to match the actual quantities constructed and measured during construction. Much of the additional cost can be attributed to design changes associated with leaving property owners with maintainable yards following construction.  In an effort to eliminate excessively steep slopes, several integral sidewalk retaining walls were constructed.  In each of these locations, the planned 4-inch thick sidewalk had to be replaced with 6-inch thick, reinforced sidewalk.  In several locations, stamped concrete was used in lieu of a narrow strip of grass.  Experience has shown these narrow strips of grass rarely survive and result in future erosion control issues.  To further flatten slopes for property owners, additional grading work was performed, which lead to a significant increase of sod for the project.  Finally, several water meters were relocated in an effort to make room for several relocated utilities.

Perry Allen, Construction Manager
