DAU does not maintain solicitation templates.  However, if you have no in-house examples, I recommend going to SAM.gov and do a search on construction and/or reprocurement.  You should be able to use a lot of the language from the original contract, and add "that trade off will be part of the evaluation methodology".

Since you are Army, I recommend this site: https://www.usace.army.mil/Business-With-Us/Contracting/ . Check out the "Useful Links" for similar Army contracting opportunities, and use the "Resources" drop down tab for USACE specific contracting guidance.
