In plain English
FAR 52.214-12, Preparation of Bids, is a solicitation provision prescribed at FAR 14.201-6(f), most recently dated Apr 1984. The complete official text is reproduced below, verbatim, from GSA's published FAR source files.
Its text contains no sentence requiring insertion into subcontracts; see the flowdown section below for what that does and does not mean.
Does it flow down to subcontracts?
No flowdown mandate found in the clause text
This is a solicitation provision — it applies to offerors when submitting an offer, not to contract performance, so subcontract flowdown is generally not the operative question for it.

The official text, verbatim
As prescribed in 14.201-6(f), insert the following provision:
Preparation of Bids (Apr 1984)
-
(a) Bidders are expected to examine the drawings, specifications, Schedule, and all instructions. Failure to do so will be at the bidder’s risk.
-
(b) Each bidder shall furnish the information required by the solicitation. The bidder shall sign the bid and print or type its name on the Schedule and each continuation sheet on which it makes an entry. Erasures or other changes must be initialed by the person signing the bid. Bids signed by an agent shall be accompanied by evidence of that agent’s authority, unless that evidence has been previously furnished to the issuing office.
-
(c) For each item offered, bidders shall (1) show the unit price, including, unless otherwise specified, packaging, packing, and preservation and (2) enter the extended price for the quantity of each item offered in the "Amount" column of the Schedule. In case of discrepancy between a unit price and an extended price, the unit price will be presumed to be correct, subject, however, to correction to the same extent and in the same manner as any other mistake.
-
(d) Bids for supplies or services other than those specified will not be considered unless authorized by the solicitation.
-
(e) Bidders must state a definite time for delivery of supplies or for performance of services, unless otherwise specified in the solicitation.
-
(f) Time, if stated as a number of days, will include Saturdays, Sundays, and holidays.
