Questions and Answers RFP No. 304T-26-072A1.1 Title:

Question No. Question Answer

In the Q&A, page 7 of 7, Question 28, it calls out “Required accuracy is +/- 1%, measure applied to line mil thickness and width.”

In the attached Special Provision discussing standards for material application in the State of Texas, starting on page one at the very bottom paragraph and continuing onto page two, it calls out a tolerance of +/- 10% for thermoplastic application. It states “These factors include variables such as the data logging system or method used, pump wear, specific gravity differences from batch to batch and manufacturer to manufacturer, and temperature differentials during material application, etc.” We have consulted with the main vendors of control systems and dataloggers for thermoplastic units and they are in agreement that +/-1% measurement of line thickness and width is not feasible. The aforementioned State guidelines of +/- 10% are much more realistic, though greater accuracy may be possible depending on the type of system used (material volume measurement

vs. laser measurement). Our opinion is that any manufacturer that claims to meet +/- 1% accuracy is making a claim that is not based in tested results.

10% is acceptable.

Also, following from the previous question, Question 28 seems to indicate that line thickness and width must both be measured. With some systems thermoplastic volume applied is measured, line width is input by operator, and material mil thickness is calculated. In this case, accuracy of thickness measurement will be dependent on accurate input of line width. Is this acceptable?

This is acceptable.

Question 27 on page 7 of 7 discusses the requirements of bead loading as 350 pounds per minute, per individual tank. Does this indicate loading both tanks simultaneously for 700 pounds per minute total? We expect the 185 cfm air compressor specified would limit flow to around 350 pounds per minute total and only one tank could be loaded at a time.

Only one tank is required to be loaded at a time.

Equipment Specification Attachment G, Option 9 specifies “Laptop or PC-based data loggers will not be accepted.” Is a touchscreen display with PLC & PC back-end system acceptable? Or must data system be an embedded system?

An embedded data system is not required.

#13: Page 8 of 13, PART II, Section 10: “PRIMARY DIGITAL DISPLAY: …The display must be easily visible to the operator, located between the handlebars, and showing the following functions:”

Q: Will the DOT explain what is meant by “located between the handlebars” in this section? The handlebars are to what?

See page 1 of this addendum.

Addendum No. 4

#15: Page 12 of 13, Part V, Section 7.: 7. “OPTION NO. 7:

COMPLETE SET OF OVERHAUL MANUALS: In addition to the manuals required in Para. 20 Part II, one complete set of specialized major overhaul/technical manuals for the engine, transmission, hydraulic system, paint system, electrical system, etc., must be provided at time of delivery.”

Q: We do not have nor do we offer overhaul manuals on the “paint system” and would not know what we could provide for this. Will the DOT consider removing the “paint system” overhaul manual requirement in option 7?

It is a requirement to provide a technical manual or schematics that show a layout of the hydraulic, paint, and electrical systems.
