Addendum No. Four Side Loader 31-Yard Refuse Truck Bodies

RFB No. 22-0042

Acknowledgment of receipt of Addenda must be included with sealed Bid.

Initials: Company:

Vendors are informed that the above subject Request for Bid (RFB) is hereby modified, corrected, or supplemented as specified, described and set forth in this Addendum:

A. Changes to the Specifications

The Public Works Department determined the requirement for a chain lift due to the following factors:

Advantages of chain drive Disadvantages of a hydraulic side loader system The chain driven system is more versatile than the hydraulic system for short and long distances. The hydraulic system is limited with the cylinders it uses.

During operation, the hydraulic arm causes instability when dumping the trash cans at a high elevation.

A number of shafts can be driven from a single chain which is needed to grab and dump the trash cans.

Hydraulic operations allow the vehicle to shift excessively both during the initial movement toward the trash can and during the upward motion to dump the trash can.

They are compact and have small overall dimensions ideal for side loader daily mission.

Hydraulic systems require intensive and periodic maintenance.

They do not present a fire hazard. Systems frequently require costly repair parts.

Temperature and environmental conditions do not affect their working.

The risk of accidents increases due to operation failures mechanically.

They do not require initial tension or a certain PSI to operate.

Repair and maintenance are drastically lower than hydraulic systems.

Due to concerns raised regarding this requirement it has been determined that an equipment demonstration will be scheduled for all vendors submitting a bid for this solicitation. The purpose of the demonstrations is to confirm the equipment meets certain criteria and equipment will be scored accordingly. The City will provide exact dates and times for the demonstrations after receipt of bids.

Demonstrations will be conducted at the City’s sanitation yard located at 1400 Cusseta Road, COLUMBUS CONSOLIDATED GOVERNMENT

2) Functionality of the arm during operation;

3) Overall vehicle response when the arm is engaged.

Scoring will be based on the performance of the equipment with each criterion receiving a score between 1 and 5 per the following scale:

1) Omitted something essential;

2) Did not meet expectation;

3) Met expectation;
