2. Q: Can a crane be set up on the east side of the site adjacent to the ramp that leads to the debris deck?

a. District Response (Aus�n): This can be found in Amendment 3 Item #9: Drawing Sheet S-

112 Structural Details 3 of 3.

7. Q: Regarding unloading the rake equipment, what is the single heaviest item? How heavy are the

HPUs?

a. Supplier Response (Lakeside): The heaviest part is the telescope, which weights 1,897 lbs. The HPUs weigh 75 lbs. each.

8. Q: How long can the shipping containers stay onsite?

a. District Response (Josh): For the delivery at PS#1, the freight company had an unloading window prior to charging addi�onal fees. The District’s opera�ons team had no issues unloading within the alloted �meframe.

a. District Response (Aus�n): This is for the piping and fi�ngs not supplied by Lakeside, related to Bid Item 17. The intent with this bid item is to capture any addi�onal piping and fi�ngs required to complete the project in the event the materials from Lakeside fall short.
