RESPONSE TO QUESTIONS:

1. Will a staging area be designated for this project?

A staging area will be designated by Frederick Water in coordination with Carmeuse prior to construction.

2. Please confirm that a Geotechnical Report is unavailable for the project area.

Confirmed. Frederick Water has no geotechnical report for the Project area.

3. Is a Land Use Permit required for the project?

A VDOT Land Use Permit is required for Work within the VDOT right-of-way. In accordance with the Contract Documents, the Contractor is responsible for determining, obtaining, and paying for permits required for performance of the Work unless specifically stated otherwise in the Contract Documents.

4. Are there any minority or small and/or local business goals affiliated with the contract?

No specific minority-owned, small-business, or local-business participation percentage or goal has been established for this Contract.

5. Are there prevailing wages for this contract?

No project-specific prevailing wage requirement is included in the Contract Documents.

6. Who will be responsible for road/site repairs due to pre-existing conditions? For example, if a roadway is susceptible to potholes due to thin asphalt or unsuitable material, will the Contractor be compensated for repairs not due to construction?

Existing conditions shall be documented prior to construction. The Contractor shall comply with all VDOT Land Use Permit and restoration requirements, and no additional compensation will be provided for work required to satisfy those requirements.

7. Due to the complexity of the project, please consider extending the bid due date.

Frederick Water will not be extending the bid due date. The bid due date remains as stated in the Contract Documents.

8. Is the demolished shed to be restored afterwards?

No. The existing shed shall be demolished and removed from the site and shall not be replaced or reconstructed. Demolition, removal, and lawful disposal shall be included in the Contractor's Bid.

9. Will a shutdown need to be scheduled for quarry operations during the open-cut installation of casing?

A shutdown of quarry operations is not currently anticipated as part of the Work. The Contractor shall coordinate its construction activities with Frederick Water and quarry operations to minimize interference with ongoing operations. Any activity requiring interruption of or significant disruption to quarry operations shall be coordinated in advance and shall not proceed without prior written approval.

10. Addendum No. 1 specifies open-cut work for casing installation. Section 33 05 05, Paragraph 1.3.B states that VDOT regulations generally require installation by boring, pushing, or jacking and that inclusion of the Section does not constitute VDOT approval of open cut.

a. Has the VDOT Land Use Permit been applied for or issued, and does it expressly authorize the pavement cut as required by Paragraph 1.3.A?

VDOT has indicated approval of the proposed open-cut crossing; however, the formal VDOT Land Use Permit has not yet been issued. The awarded Contractor shall apply for and obtain the VDOT Land Use Permit, with Frederick Water providing any required Owner authorization. Open-cut pavement construction shall not begin until the issued permit expressly authorizes the pavement cut.

b. If VDOT does not authorize open cut, will trenchless installation of the casings be treated as a change to the Contract compensable under General Conditions Article 11, or does Frederick Water consider that scope to be included in the base bid?

The Base Bid shall be based on open-cut construction. VDOT has indicated approval of the proposed open-cut method. If the final VDOT Land Use Permit requires a materially different installation method, the matter will be addressed in accordance with the Contract modification provisions

11. Are there any railroad restrictions or requirements for the work areas nearby?

Frederick Water is not aware of any railroad restrictions or requirements applicable to the Work. If railroad requirements are subsequently imposed that constitute a change in the Work, they will be addressed in accordance with the Contract modification provisions.

12. Section 31 20 00, Paragraph 3.9.K requires VDOT 21A/21B select fill from 1 foot above pipe to within 6 inches of grade for trenches within VDOT right-of-way and on quarry property. Since the entire alignment is on quarry property, does select fill apply to the full 4,700 LF, or only within the VDOT right-of-way?

The VDOT No. 21A or No. 21B select-fill requirement applies only to trenches within the VDOT right-of-way.

13. Does any subsurface, rock-probe, or boring data exist for the alignment?

No. Frederick Water has no subsurface investigation, rock-probe, boring, or geotechnical data for the pipeline alignment. Bidders shall base their Bids on the information contained in the Contract Documents and their examination of the Project site.

14. Section 31 20 00, Paragraph 3.3.B.6 says remove rock to 6 inches below pipe;

Paragraph 3.9.F says 12 inches below pipe with 12 inches of aggregate. Which governs?

Section 31 20 00, Paragraph 3.3.B.6 is hereby revised to be consistent with Paragraph 3.9.F for utility trenches.

15. Section 33 12 43, Paragraph 1.1.B defers all meter electrical, conduit, power, grounding and SCADA work to the Drawings, but there is no Division 26 specification in the Project Manual. Please confirm the full electrical/SCADA scope.

Division 26 – Electrical is included with this Addendum and shall become part of the Contract Documents. The Contractor shall provide the electrical work required for the magnetic flow meter, including conduit, power wiring, signal wiring, grounding, terminations, and associated electrical components required for a complete installation, in accordance with Division 26, Section 33 12 43, and the Drawings.

Frederick Water will be responsible for SCADA programming and system integration.

16. Mag Meter Electrical / SCADA Requirements- We did not locate electrical drawings or specifications showing the electrical requirements for the mag meter. Sheet 4 of 5 indicates that two 2-inch conduits are required. Could the following information be provided?

Source panel/location? Chlorine Building Required voltage for the mag meter? 115 Voltage Single Phase SCADA termination points? – Chlorine Building to Manhole Party responsible for SCADA programming and system integration, if required?

Frederick Water is responsible for SCADA programming and system integration.

17. Berm / Imported Fill-The drawings contain several notes stating that the pipe may be installed at existing ground level and covered with a berm to obtain the required 48 inches of cover. Is suitable material for constructing these berms available onsite, or should bidders include importing suitable fill material in their bids?

Suitable material for construction of the berms is available onsite. Onsite material used for berm construction shall meet the applicable requirements of the Contract Documents.

18. VDOT PAVING REQUIREMENT-Please confirm the required paving section, including stone base, asphalt thickness, and whether milling and overlay will be required.

Pavement restoration shall be in accordance with the issued VDOT Land Use Permit and approved restoration detail. Aggregate base and asphalt types and thicknesses, including any required milling and overlay, shall be as required by VDOT.

19. Is an engineer’s estimate or estimated construction value available for the project?

No Engineer's Estimate or estimated construction value is available for this Project.

20. Who is responsible for providing and paying for the water required for filling, flushing, and pressure testing the new waterline?

Frederick Water will provide the water required for filling, flushing, and pressure testing the new waterline at no cost to the Contractor. The Contractor shall be responsible for coordinating the water source, connections, filling, flushing, testing, discharge, and disposal in accordance with the Contract Documents.
