COMMERCIAL QUESITONS AND GENERAL

1. What is the intended timetable from submittal of bids to Notice of Award (NOA); NOA to Notice to Proceed (NTP); NTP to Pre-Construction Meeting; and anticipated/required mobilization date? NOA will be a few days after proposal due date, notice to proceed with then be issued and must start work within 10 days.

7. Is there any analytical sewer discharge data available? No

8. Due to the materials of construction and age of the sewer system, jet cleaning may indirectly cause unintentional damage by exposing existing deficiencies to the existing pipe. In such cases, it would be in DANG’s best interest to perform repairs at the time of discovery. Does DANG have an allowance to cover this type of event(s)? Unknown at this present time.

2. Please clarify the DRBA limits and authorities required for discharge location and any notifications will be noted on the map

3. Can DANG provide any Lift Station Drawings, Maintenance Logs, Operational history, analytical data? If available, will be provided to the contractor awarded the job at the precon mtg

4. Will any work be performed in the Munitions area? NO

5. GIS Submittal – Will DANG supply a geo-referenced Base file of the DANG Facility of concern that shows the existing sewer systems (sanitary and storm) in a .DXF or .DWG format, which will be provided to the successful Bidder? Yes

6. What is the acceptable format to be assumed for the GIS file? What Coordinate system does DANG use? Delaware State Plane? ??

7. Base Access – Once an award is made, will badges be issued for the length of the project to streamline the entry process? Yes

8. Active Landing Areas - Please clarify what procedures may be required for potential access to restricted areas, such as; notice time requirements, permitting procedures, etc. None forseen

9. Radio or Cell phone Transmission Restrictions – Please indicate where these restrictions exist other than the Munitions area. NA for the realm of this project

10. Photo Documentation – Are cameras allowed on-site to document any site conditions or other project features? Yes, except around aircraft

11. Clean Up - Does DANG have a list of approved off-site facilities for disposal or a designated area for stockpiling of debris recovered from the sewer cleanings, if required? No onsite stockpiling will be allowed. Contractor to determine where materials can be appropriately disposed of

12. What quantity of waste debris should Bidders assume for bidding purposes? Assume an average amount based on experience

13. Sewer Jet Cleaning Decant Rinseate – Please indicate which manhole will be used to off-load/de-cant liquids from the sewer jet truck. Will be indicated on the map and discussed at the precon meeting

14. As already mentioned, please provide any quantity or quality limitation requirements before discharging to the designated manhole.

15. Work Schedule – Please indicate any long term “NO WORK” dates scheduled during the expected POP for this work. Every other Monday is a down day. Work can be scheduled with coordination. Any federal or state holiday observed during the course of the job

16. Confined Space (CS) Permitting – Please provide DANG procedures for CS Entry. Typically, this type of work requires two manholes to be open at one time to allow the camera and jet cleaning to run simultaneously. For the most part, breaking the plane is not required for investigation. However, please indicate if DANG procedures allow more than one entry at a time? Yes Also, Is there a limit on manholes open at one time, assuming they are adequately guarded? No

17. Line abandonment – Based on the SOW, this is not included in the solicitation. Please confirm. If line abandonment is required, please specify what method is to be priced and diameter(s) and length(s) of pipe need to be abandoned. If noted as abandoned, inspection is not required.

18. Are you interested in smoke testing the system and will it be part of this scope of work? Can be submitted as an option

19. Are you interested in doing manhole inspections to the NASSCO MACP standards? There are two levels, level 1, which grabs basic information about the asset.

20. Is flow monitoring part of the scope of this project? If so, do you have an estimated amount of meters as well as a montoring period (3 months, 6 months, etc.) NO

21. If flow monitoring is part of the scope is it safe to assume you just want a hydraulic analysis and not a model. Building a model is a bit more involved than just a hydraulic analysis. N/A
