TITLE:

Consideration and Approval of Contract: Wildcat Hill WRP emergency crane repair 

STAFF RECOMMENDED ACTION:

  1. Approve the contract with Kone Cranes for the repair of the overhead Crane used to move Sulfur Dioxide chemical containers in the amount of $ 53,646
  2. Authorize the City Manager to execute the necessary documents.

Executive Summary:

This is a confirming approval of an emergency repair. During our annual inspection staff was informed by the contracted inspection company (Kone Cranes) that there is a recall on our Sulfur Dioxide Crane Rail. Overhead cranes require this inspection annually as part of the OSHA Standard 1910.179. Now that we know this is a potential danger, we must either repair it or quit using it. This equipment is utilized weekly to move 1-ton Sulfur Dioxide containers so that we can place them on scales so that we can track usage.  We have no way to unload the Sulfur Dioxide containers from delivery semi-trucks or move them inside the building. We will be utilizing emergency funds for this Project.

Financial Impact:

Water Services will be using a portion of the FY 2020-21 budget in account # 203-08-375-3235-0-4421 emergency reserve in the Wastewater Fund. This repair was not budgeted, however is critical for staff and public safety.

Has There Been Previous Council Decision on This:

No prior discussion

Options and Alternatives:

Approve the award as recommended. All work has been safely completed.

Background and History:

The Wildcat Hill WRP Sulfur Dioxide overhead crane was installed when the facility was built in 1982. During the annual inspection of plant crane equipment this year it was noted that this crane system has a recall, was tagged as unsafe and should be replaced as soon as possible.

Chemicals represent a large investment in the effective operation of wastewater treatment plants.  Wildcat Hill Water Reclamation Plant uses the chemical Sulfur Dioxide to remove chlorine from reclaim water that has been chlorinated for disinfection.

The procurement justification for this purchase is approved as an emergency purchase. Due to the critical need and nature of the equipment, procurement allowed this project to move forward on an emergency basis.

Key Considerations:

  • Overhead cranes used to safely move chemical containers and are a critical part of our WWTP operation.
  • Failure of crane assembly would result in a OSHA permit violation.
  • Sulfur Dioxide is utilized to reduce Chlorine residual within reclaim water at Wildcat to below permit level of 0.009 mg/l. Without this chemical reaction, COF would be in violation of the ADEQ allowable permit level.

Community Benefits and Considerations:

Community Involvement:

These repairs will ensure that this crane equipment will be functional for at the next 20 Years. It will ensure staff can safely transport chemical containers. It will also serve to ensure public safety.
