Pre-Proposal Meeting on 05/14/2025: Bidders Questions/ FFDG Response

Please find the Bidders questions below asked during the Pre-bid Meeting and FFDG response in blue below:

Q1) Do all of the Subcontractors people who are underground need to have all of the ESH certifications?

A1) No, they require the certifications that are only necessary to do the job requirements. For example, if there is no electrical work to be done, then that certification is not required.

Q2) Is all of the testing required by the Subcontractor or will FFDG perform some of the testing?

A2) All of the testing equipment and testing is to be provided and performed by the subcontractor. FFDG will be present during testing to coordinate and observe.

Q3) The RFP requires a dedicated ESH Representative to be onsite for the work being performed. A resume was requested in the RFP. Is this correct?

A3) The resume requirement comes from document A-2. A foreman/competent person can represent for the ESH requirement if they are appropriately trained in ESH. 30-hour OSHA is a Fermilab/FFDG requirement for an ESH competent person to provide oversight for ESH.

Q4) How long does guide training take?

A4) Guide training will take 1 to 2 days. A guide will be provided for Task Order 1 testing program.

Q5) Will a person be required to be guide trained for Task Order 1?

A5) No, FFDG to be guide for the test program.

Q6) Will we provide participating attendees?

A6) Yes - See Attachment A.

Q7) Ross Cage specifications - Slide did not detail weight and height clearly.

A7) Please see document Attachment B for dimensions and weight limits.

Q8) What is the duration after application for testing requirement?

A8) The specifications indicated that the length of time was minimums. Offerors need to provide recommendations in their proposals as different materials take different lengths of time to cure prior to testing.

Q9) Will testing be required for Chloride?

A9) Offeror can propose alternative specifications that would achieve the requested performance requirements depending on the chemicals they propose to use.

Q10) What would typical working hours be after cage time/travel time etc.

A10) Cage travel time down is roughly 10 minutes. Cage travel time up is roughly 5 minutes. The maximum amount of people on a cage is 29. The cage down and up times for the Ross shaft are in the table below. Other shifts or night shifts may be available but will need to be discussed for possibility.

Q36) Is there a continuous concrete slab between the shaft and the work area? Is the travel way level or is there a grade to it? We can only find manual pallet jacks in your area for rent, and the electric scissor lifts that fit in your cage need a fairly level surface.

A36) There is a continuous concrete slab from the Ross cage to the 4850-40 spray chamber. Please see Attachment E for images of the track that are in the concrete slab.

Q37) What voltages are available at the site? Our equipment is designed for 600V, and a transformer may be necessary.

A37) Please see response to Question 17 above.

Q38) Are we to provide the adhesion and thickness testing and test equipment on site?
