RFI # Date Question Response Response By & Date

1 12/7/2020 Is there something other than peastone that existing net post foundations can be filled with after they are pulled?

Sand or gravel can be used as backfill, provided it meets the compaction requirements as noted in the specifications in terms of lifts and compaction proctor

Michael Sims, 12/10/20

2 12/7/2020 Can Laykold Qualipur 152 also be acceptable as the required Stain Blocker? Laykold Qualipur 152 is acceptable Michael Sims, 12/10/20

3 12/7/2020

There is no specification provided for necessary concrete prep pertaining to the post tension concrete. Can you please clarify how you would like the surface of the concrete prepped?

This will be clarified with Addendum. Michael Sims, 12/10/20

4 12/9/2020 Regarding the curb drops, are we to cut those out and replace them so new walk is flush with top of curb?

The curb drops are existing and you are to pave new concrete flush with edge of top of curb Michael Sims, 12/9/20

5 12/10/2020

Sheet LD1.03, Detail #5 shows fence fabric on the outside of the batting cage posts. Detail #4 does not show any chainlink. Please clarify

There is no new planned chainlink fence around the new batting cage. Michael Sims, 12/10/20

6 12/10/2020

I assume the new concrete walk will match the top of curb along the roadway when it dips down to meet the existing curb, it may not be in ADA spec.

You are correct, it may not meet ADA. Michael Sims, 12/10/20

7 12/10/2020

If we are to put in new curb, should we match what's there (looks like straight face curb) or install 18" curb and gutter and match the existing asphalt

We shouldn't need any new curb, but if new is needed for your work, plan on a straight face curb to match existing. Michael Sims, 12/10/20

8 12/10/2020 Are you looking for a tennis court mix below the synthetic turf in the baseball area?

No, we will clarify this with Addendum to be a general paving mix Michael Sims, 12/10/20

2. All cables shall be supported on chairs and loosely tied two inches (2”) high at all intersections (too tightly tied, tendon friction will increase when tensioning) to prevent vertical and horizontal movement during concrete placement. Strands shall be placed with no greater spacing that two feet (2’) six inches (6”) wide in both directions. See drawing details for cable spacing.

3. After the forms are removed and the concrete has set to a minimum of 2,000 psi, the tensioning procedure may be applied.

4. Each tendon may initially be tensioned to a maximum of eighty percent (80%) of ultimate breaking strength and anchored at a minimum of seventy percent (70%) of ultimate breaking strength.
