Below are responses to questions received prior to publication of Q & A #1.

Bid Opening is extended to 08/15/2024

Specification Questions:

Q1 Would the state please consider alternate joystick configurations since the system as specified is proprietary to a singular body builder?

A1 Tollway - The joystick design was to meet the Tollway requirements for proper operation and safety, we are not looking for an off the shelf standard model. The Tollway will review and approve a joystick design that can be built to equal or exceed those features that are called for in the specification.

IDOT - The “control system” is made up of several components. The joystick design was to meet IDOT requirements with safety features included that were not an off the shelf standard model; to IDOT’s knowledge a joystick design can be built to equal or exceed those features called for in the specification, company examples below. The controller or CPU is a Force America and is available off the shelf to any entity. Multiple DOT’s use Force America products. See Specification requirement.

Q2 Would the state please consider other hydraulic control systems if they meet similar function as the Force controllers specified.

A2 The “control system” is made up of several components. The joystick design was to meet IDOT requirements with safety features included that were not an off the shelf standard model; to IDOT’s knowledge a joystick design can be built to equal or exceed those features called for in the specification, company examples below.

Q4.4 65.K Would a Henderson 35° Sloped side Muni Body be acceptable instead of a 43” radius? It would have the following spec changes:

• 86” inside width to the toprails, with an 85” width to the side sheets.

• Toprail sloped to inside (due to internal toprail)

• Conveyor width of 28.5” and pintle chain width of 25.125” center to center. Each link would be 1.25” x .375”

A4.4 Yes, Tollway will review alternative designs equal to or greater than the specification.

Q4.5 62. GG-QQ. The hoist specifications describe a discontinued cylder that has since been revised from this specification. Would the state consider revising this section with:

• Cylinder shall be bleederless and capable of operating at 2500 PSI.

• The cylinder shall be a trunion mounted telescopic. It shall be installed with the largest stage at the bottom for stability. An inverted telescopic hoist will not be accepted.

• All components of this cylinder except for the seal kit shall be processed through a liquid salt bath nitriding treatment to enhance the surface hardness and corrosion resistance. Hardness achieved will be Rockwell C scale 55 – 60, and corrosion resistance will be roughly three times that of hard chrome plating.

• The cylinder shall be a rod seal design, with seals and wipers installed at the top of each section. Tubes will be surrounded by oil when retracted.

• There will be an oscillating collar on the outer cover of the cylinder to allow the body to be offset 5º to 7º without transferring that side load to either the truck frame or the cylinder tubes, and therefore enhancing stability, and longevity.

• The cylinder shall be assembled from the bottom and have no threaded gland nuts.

There shall be no wear bands in this cylinder as the hardened steel tubes are designed to run adjacent to one another on a thin film of oil."

A4.5 Yes, Tollway will review alternative designs equal to or greater than the specification.

The Auger Drive Hydraulic Motor shall have an integral built in speed sensor. The speed sensor shall supply a minimum of 100 pulses per revolution. The speed sensor shall include a Brad Harrison type of connector to the unit.

The sensor when fastened in or on the hydraulic motor shall provide a sealed environment for the “pickup” end of sensor. Open shaft sensors that expose “pickup” to the elements are not acceptable.

Sensor below is sealed once electrical connection is made.
