6. Question: Is it acceptable to dispose of the asphalt road surface to the City Yards? Answer: Yes.

7. Question: Is there a second access to James White Park?

Answer: Yes. There is a second access to the park at the North end.

8. Question: What is the valve actuator for at the North West Reservoir? Answer: The actuator will automatically operate an existing valve for the purpose of allowing a fill cycle in the tank from the well source.

9. Question: Which watermain is being tied into at HWY #3 (western end of river crossing)? Answer: The tie in is shown on Drawing C04.

10. Question: Are the restraints and thrust blocks required? Answer: The proposed pipe material is HDPE DR9 and DR7.3. At alignment deflection points 45 degrees and higher we require restraint against thrust. The anchor blocks shown on the drawings are intended to prevent undue stress on the pipe resulting from temperature changes and the Poisson effect.

11. Question: Will you consider approved alternates for the pumps? Answer: During the design phase, the City undertook a thorough competitive process to select the pumps. The successful bidder may propose alternates with their Bid.

12. Question: Who is the BC Hydro contact for the JWP Project? – Is the main transformer supplied

by BC Hydro? – Is the utility pull box going to be supplied by BC Hydro? – Who is the designer? Answer: Matt Johnston at BC Hydro in Cranbrook will be the contact. – The main PMT (pad mounted transformer) is provided by BC Hydro. – The utility pull box is to be provided by the Contractor. – BC Hydro will be providing a final design from the existing 25 kV power pole to the PMT and directing Contractors to their underground distribution standards as necessary. The following is an excerpt from the BC Hydro Secondary Metering Guide – “Contact BC Hydro and refer to the ES53 Series Underground Electrical standards and the ES54 Underground Civil standards for underground main service conduit, wireway and pull box requirements.” Another excerpt from a BC Hydro guide for reference – Item D. Installation of industrial services: - Responsibility for installation is divided in the following manner:

• Supply/installation of most civil materials and labour on both public/private property (subject to municipal requirements) is the customer’s responsibility.

• Supply/installation of all required electrical material (e.g., transformers, cable) will be by BC Hydro.

• Electrical cables/transformers, etc., will be installed by BC Hydro after completion of civil works and acceptance by BC Hydro.

• Pole installation on public property is done by BC Hydro and is subject to municipal approval.

• Customer’s contractor will install metering transformers and cabinet.

13. Question: I would like to get some clarification on drawing E004. Are we supplying conduit/wire from 300m away or is that part existing and we are doing the terminations only as shown on drawing E004?



Answer: Clarification on drawing E004. The conduit and wiring between the NW reservoir chamber and chlorine building are existing, approximately 300m in length. Wiring and connections to the Rotork valve and PLC shall be provided by the Contractor per the control block diagram.

14. Question: Who is responsible for compaction & proctors? Is it the owner or the GC? Answer: Refer to Section 01 43 00 – Quality Assurance.

15. Question: Would two 45 degree bends on the 500mm HDPE at station 0+268.31 be preferable to a 90 degree bend? Answer: A 90 degree bend or two 45 degree bends are acceptable.

16. Clarification: Note 2 on Drawing P03 applies to the buried watermain as well as process piping.

17. Question: There is an exposed aggregate finish on the well houses which not all suppliers do. This exposed aggregate finish will limit my ability to get competing quotations. Answer: The exposed aggregate finish is required, therefore, only suppliers able to provide this finish should be considered.
