DAD003 ADDENDUM 8 ADD#8 - 2

QUESTIONS FROM BIDDERS The following questions were received from bidders. Answers to the questions are considered incorpo-rated into the Contract Documents & Specifications and Construction Plans for the project.

1. The specifications call for a 0.375 Wall 20” steel Surface Casing, and a 0.307 Wall 16” Primary Casing. They do not make a 0.307 wall, only a 0.312 wall. The Industry Standard is normally a 0.375 wall. A 2” minimum annular is required for all Community Public Supply Wells Constructed by Rotary Drilling. A 24” 0.375 wall is 23.25” ID, and a 16” is 16.00” OD and 15.25” ID. This annu-lar spacing also allows for The installation of tremie piping to complete the grouting without complications. Will Engineer accept 24” 0.375 Wall Steel Surface Casing, and a 16” 0.375 Wall Steel Primary Casing? Answer: The intermediate casing is changed to 24” diameter and the surface casing is

changed to 30” diameter. The casings shall have 0.375” wall thicknesses. The 0.307” wall thickness is for a 10” steel casing. Drawing M-01 is revised to reflect these changes.

2. Will the Engineer accept Installation of the surface casing, by driven method using Number-8

Bentonite grout, with drive shoe? This is an approved method by the Water Management Dis-trict. Answer: The bids shall be based on the methodologies listed in the specifications and actu-

al construction methods can be discussed and approved after award and prior to construction.

3. The specification’s call for specific capacity test using a submersible electric pump minimum of

250 GPM at depths of 370, 410, 450, and 490 feet. What is the expected Run time for each test for bidding purposes? Answer: Per the specs, the pump duration is based on the groundwater level stabilizing be-

fore termination of the test. For bidding purposes, Contractor shall use one hour as the basis for the test duration.

4. The specifications call for a video survey upon completion of the well construction, and Testing. Is

Static, and Dynamic Geophysical Logging Required? Answer: No additional logging is required.

5. How far will the Contractor be required to run discharge piping for well testing with pumping

equipment? Answer: The Contractor shall be required to provide temporary containment on site of the

well discharge during drawdown testing. This distance should be within 150 feet of the well but the actual location is at the discretion of the Contractor and ap-proved by the Engineer and/or City.

6. What is the anticipated NTP?

Answer: It is currently anticipated that the NTP shall be issued in the fall.
