City of Garden Grove
INTER-DEPARTMENT MEMORANDUM
| To: | Scott C. Stiles
| From: | John Montanchez
| | Dept.: | City Manager
| Dept.: | Community Services
| | Subject: | Approval of Change Order No. 1 to the McWil Sports Surfaces, Inc. contract for added secure moisture barrier protection to the new gymnasium floor. (Cost: $44,984) (Action Item) | Date: | 4/9/2019 |
|
| | | | | | | | OBJECTIVE
To request that the City Council approve Change Order No. 1, for the amount of $44,984, to the McWil Sports Surfaces, Inc. contract for the application of a 2-layered epoxy coating to the concrete slab flooring, to secure moisture intrusion at the Garden Grove Sports and Recreation Center. |
| | | | | | | | BACKGROUND
On February 26, 2019, City Council approved a contract with McWil Sports Surfaces, Inc. (Contractor), for the replacement of the gymnasium floor at the Garden Grove Sports and Recreation Center. The original composite gymnasium floor had warped due to moisture intrusion from the concrete slab flooring underneath. |
| | | | | | | | DISCUSSION
During the removal of the existing floor, the Contractor discovered that the level of moisture content under the floor was higher than anticipated because of cracking in the concrete slab flooring. The Contractor is willing to increase the thickness of the moisture barrier sheeting that was called out for the project. However, to further secure protection of the new gymnasium floor from any moisture intrusion, the Contractor highly recommends adding a 2-layered epoxy coating to the concrete slab flooring. Given the inability to foresee the true nature of the moisture intrusion without removing the existing floor, this was an unexpected project expense. In accordance with Garden Grove Municipal Code 2.52.030, change orders over 10% of the contract amount must be approved by City Council. |
| | | | | | | | FINANCIAL IMPACT
This request will not impact the City's General Fund. The change order total amount of $44,984 is available within the project budget, that is funded by the Park Fee fund. The change order will bring the project cost to $233,034. The total amount of funding approved for this project is $250,000. |
| | | | | | | | RECOMMENDATION
It is recommended that the City Council:
- Approve Change Order No. 1, for the amount of $44,984, for the application of a 2-layered epoxy coating to the concrete slab flooring; and
- Authorize the City Manager, or his designee, to sign and execute Change Order No. 1 on behalf of the City, including making minor modifications as appropriate and necessary.
