NOTICE NO. 2
7. Will a specification be provided for the polymer concrete listed on C3/E502? Or is the contractor to provide?
ANSWER: Contractor must provide polymer concrete handhole boxes meeting the requirements specified on detail C3/E502 of the Part A (D-B-B) provided in Attachment A of Part 6 of RFP.
Concrete ring around the box must meet the specifications provided in Attachment B of Part 6 of the RFP and the concrete strengths indicated. Additional specifications will not be provided.
8. Is the Quality Manager position identified in specification section 033000.1.6.6.1 intended to be a separate position from the QC Manager defined in 014500.1.4.1?
ANSWER: Yes.
9. Are Autocad files available? Will they be provided pre or post award?
ANSWER: Autocad files will be available to the DB Contractor post award.
10. Are Revit files available? Will they be provided pre or post award?
ANSWER: Revit files are not available.
11. Part 3 – Project Program Requirements, 6.0 Engineering System, 5, a. states “Completely backfill probe holes and any cavities detected with controlled low-strength material (CLSM) or a sand, cement, and water grout mixture using tremie methods with grout pipes”
For all of our previous probing and grouting activities at AAFB the following methodology has been utilized: Following probe drilling, completely backfill probe holes and any cavities detected
RFP N62742-20-R-1324
with grout consisting of Controlled Low Strength Material (CLSM) with a 28-day unconfined compressive strength of at least 1,450 psi. The slump of the grout shall be between 8” (203 mm) and 10” (254 mm), plus or minus 25 mm. Grout will be placed by gravity from one side of the probe holes to avoid air entrainment via a 2 inch hose set to within 1 foot below ground surface at 60 psi.
We believe that with the additional amount of time it takes to tremie grout into each probe hole that the grout will set up in the mixer and be unsuitable as the high slump “flowable fill” required to completely fill the cavities, voids & weak pockets etc. If water is added to the mix to increase slump there is no way to ensure the compressive strength. We request that the tremie method requirement be waived.
ANSWER: Bid as specified.
