12. Question: It is seems like not all documents were issued for our consideration. Different contractors were asking the same question all over again regarding water drawn test and other aspects related to geotechnical investigation, and the only answer that was received is that the contractor is solely responsible for estimating dewatering rates and hire a geotechnical firm for all geotechnical investigation; However, according to Geotechnical Reports 1 and 2, pages 11 and 14 respectively, a “…preliminary construction dewatering assessment…” has already been completed by PML and has been issued under separate cover (Technical Memorandum reference 14HF013, dated February 26, 2016). Both Geotechnical Reports also state that the “…technical memorandum should be read in conjunction with this report.”. Therefore, please could you issue a copy of PML’s Technical Memorandum reference 14HF013 to the interested parties to ensure that all investigation data is captured for the submission and reviewed appropriately. If Norfolk County is interested in getting a price of this project within a budget, this document better should be issued. Answer: See Clarification 1 in this Addendum.

13. Question: Q1: Section 13610 page 7 of 14 item 2.7.3 please clarify this statement. What are you looking for on the software.? Answer: Successful proponent will be required to have the software needed to build a working system and assist with troubleshooting. We know of no way to properly configure the system without the software. The client and programmer have their own software and do not need the successful proponent to turn over copies at the end of the project.

14. Question: Please confirm handholes are acceptable for long exterior conduit runs (fiber, lighting, etc), as it would be extremely costly to install manholes at each location. Specifications only mention manholes.

Rev. 06.17 FO-153

of 19


Answer: Handholes are acceptable.

15. Question:

Please request specifications for panelboards, transformers, distribution and pole mount. At this point, there is not enough information to provide an accurate quotation. Answer: See narrative in Clarification 2.

16. Question: The vendor/supplier does not have enough information regarding light fixture “A”: Specification 16500 Paragraph 2.6 requires furnishing of 1 spare occupancy sensor for “A” type luminaires. Type “A” luminaires do not come supplied with a built-in sensor and therefore must be supplied loose. a. How many sensors are required for this job? b. Please provide sensor requirements. Answer: This was left in in error. No occupancy sensors are required in Specification 16500.

17. Question: Please also provide more details on transformers, distribution and pole mount panelboards. There simply is not enough information to quote these equipment. Answer: See narrative in Clarification 2.

18. Question: There is a “refrigerated sampler system” shown on drawing P-3030. Please advise where this equipment is listed in the specifications. Also please advise if this unit will require a compressed air system.

Answer: The sampler is provided by facility operations and is not to be provided as part of this project.

19. Question: Would it be possible to show the locations, sizes, and elevations of all housekeeping pads, thickenings and slab built-ups under block walls on the structural plans? You can see them in the sections, but there are no dimensions, especially in the filtration room where there’s a fair bit of concrete. Answer: The location of pads are provided in both structural and process drawings. Pads which may be varied to accommodate the selected tanks, pumps or other small items have been shown on process drawings only. Elevations are based on floor slab elevations with pad thickness shown on either process or structural drawings. Details for pad construction are provided on structural drawings.

20. Question: i) Could you release the preliminary construction dewatering assessment (PML Technical Memorandum, Feb. 26, 2016) as referred to in PML Report 2 (December 2016) Section 4.6.1? ii) Since Addendum 2 stipulates that the general contractor is responsible to obtain all permits with respect to the groundwater taking, could you provide a revised schedule knowing that some time will be needed for hydrogeological testing, analysis and MOECC applications, and that the MOECC processing time for PTTW applications is up to 90 days if testing and analysis shows that an EASR is not applicable? iii) Alternatively, in order to expedite the PTTW application process, would the owner (Norfolk) consider either having their geotechnical / hydrogeological consultant begin the PTTW application process now using the information they have but is not available to the bidders, or provide an allowance for the PTTW application process? Answer: See narrative in Clarification 1.
