1. Michael Stanley with Mt. Lemmon Water

District was contacted and Nathan returned the call staƟng that Stage 3 Water restricƟons are in place and construcƟon water is not available. Will it be possible to pull construcƟon water from Rose

Canyon Lake?

Contractor responsible for idenƟfying construcƟon water source.

2. Item Number A0520 GABIONS is paid by the square foot. FP-14 253.10, " When measuring gabions by the cubic yard (cubic meter), measure in the structure. Measure foundaƟon fill under SecƟon 208." The bid schedule does not have a line item for 208

Structural excavaƟon and backfill. Please define the measurement for Gabions? Is it the front face of the wall excluding fooƟngs or including fooƟngs? If it excludes, are fooƟngs incidental or to be paid under another item?

A0520 Gabions is to be paid as stated in secƟon 253.10 of the FP-14. In situaƟons where there is lack of a pay item, all work associated with A0520 should be considered incidental with all aspects of inspecƟon and tesƟng requirements to be met.

In addiƟon, the pay item for gabions is by square foot intenƟonally as the width of foundaƟon grading and granular backfill is based on the boƩom gabion dimensions which will be up to the contractor and their design. The area provided excludes the fooƟngs.

3. Currently lead Ɵmes on CXT vault restrooms are 120 - 150 days. Assuming the contract is awarded September 18th and restrooms are submiƩed and approved by

October 18th. 150 days puts delivery on

March 17th. This only allows 34 working days to install the restrooms and all surrounding work. Can the contract compleƟon date be pushed into June.

To be coordinated with CO. Current restricƟons to Mexican SpoƩed Owl habit could conflict with contract compleƟon date extension.

4. Please confirm for concrete placements using a hydraƟon stabilizer admixture that FP-

14 552.03 (I) (3) "maximum allowable design discharge Ɵme is 3½ hours," will not apply.

Bid as adverƟsed. FP-14 552.03(I)(3) will apply on this contract. The project is not that remote. 1.5 hours from Tucson. The 3.5-hour discharge Ɵme should not be a problem.
