AMENDMENT 0007

The following RFI questions have been submitted regarding this solicitation, representing most of the questions submitted to the Contracting Officer after the deadline established in Solicitation No. 36C252-19-B-0045. Bidders are instructed to submit their bids in response to the solicitation “as-is”, taking into consideration all Amendments issued to date. Any remaining issues will be addressed with the successful bidder. Questions and responses are provided for bidder’s information and use.

RFI QUESTIONS/ANSWERS:

1. QUESTION: Since the area is being converted from an in-patient mental health area to a outpatient and office area, do we still need to use institutional (anti ligature) sprinklers?

ANSWER: No, institutional (anti ligature) sprinklers are not required in office areas.

2. QUESTION: Please confirm that the facility maintenance will be responsible for isolating existing systems, draining, and positive means of isolation if an existing valve fails to function properly for planned shutdowns/outages.

ANSWER: The contractor is responsible to isolate and drain. If the valve does not function, Contractor will request an Additional Work Authorization.

3. QUESTION: Call for the removal and salvage of radiant heat panels. During the site walk we were not permitted to view typical rooms/installation/locations where radiant heat panels were located. Can the facility provide photographs of typical conditions or schedule another site visit to view typical scenarios?

ANSWER: Radiant heat panels were located in the rooms shown during the site visit, 3rd and 4th floor. See Attachment #2 for current condition photographs.

4. QUESTION: Note 4 calls states "RE-INSTALL RADIANT PANELS OF TYPE AND QUANITY INDICATED. COORDINATED WITH ARCHITECTURAL CEILING GRID DRAWINGS". To remove, salvage, and reinstall existing radiant heat panels poses significant risk on the contractor by taking responsibility of products that may be structurally compromised as we've seen at Lovell FHCC. The tradeoff of removing and installing new could offset the costs, minimize risks, and provide a new system that could be warrantied. Please advise if new radiant heat panels are desired under this project in-lieu of utilizing existing.

ANSWER: Contractor is responsible for removal, storage and re-install of existing panels.

5. QUESTION: Existing conditions above ceilings are largely unknown and routing is depicted as straight lines. Will the VA provide a Not To Exceed CLIN to cover costs of unknowable offsets necessary to install new plumbing around existing conditions? Off-sets on previous Legionella projects exceeded estimated quantities by 300-400%.

ANSWER: The project is bid as a lump sum. Any additional equipment and materials will require an Additional Work Request.

6. QUESTION: Plumbing Mat'l and Procedures notes; Note 11 calls for service valves at branches and at ALL APPLIANCES. Please confirm that all valves are depicted in P100 through P400 or if additional valves are required on Cold Water and Hot water lines at each fixture.

ANSWER: Service shut-off valves are not shown and are to be included for each appliance.

7. QUESTION: Plumbing Mat'l and Procedures notes; Note 10 calls for 1/2"x12" air chamber on the Cold Water and Hot water lines at each fixture. Please provide a detail of typical piping at fixtures with CW & HW as well as CW fixtures only.

ANSWER: See Attachment #3 for detail.

8. QUESTION: Confirm door frames do not need to be grout filled solid. If grout filled frames are required, please indicate locations of frames to be grout filled.

ANSWER: Doors do not need to be grout filled.

9. QUESTION: Please confirm that FEC located within hatched areas show as "AREA NOT IN CONTRACT" are in fact not part of the contract. The line weight leads bidders to believe that an additional 8 FEC's will need to be installed. This work will require additional infection control, off hours work, and additional carpentry work.

ANSWER: Confirmed FEC located in the AREA NOT IN CONTRACT are outside of the scope of this project.

10. QUESTION: Please provide typical detail for installation of handrails and locations where handrails are to be installed.

ANSWER: Provide handrails on north and south walls of corridor C3-7. See Attachment #1 for typical detail.

11. QUESTION: Please provide information on existing Radiant Heat Panels to be removed and salvaged.

ANSWER: See Attachment #2 for current photographs. Radiant panels were custom made and do not have a spec sheet.

12. QUESTION: Solid Surface material is shown on the Room Finish Legend. However, the Furniture Plan drawings state "All Furniture Provided and Installed by VA". Please confirm that all casework related material is furnished and installed by the VA.

ANSWER: Correct all casework related material is furnished and installed by the VA. Please note that contractor is required to provide backing/blocking for future installation.

13. QUESTION: Please confirm that the afterhours/off-hours of operation activities are all inclusive and that no other work activities must be at night per the section "CONSTRUCTION PERIOD STAGING OF WORK - GENERAL NOTES". Generally speaking is there a thought by the facilities as the percentage of work that will occur between 7am and 4pm vs, 2nd and 3rd shift 5:30pm to 6am?

ANSWER: After hours work to be coordinated with VA and may include activities not mentioned in "CONSTRUCTION PERIOD STAGING OF WORK - GENERAL NOTES". There are no estimates as to the amount of work required during normal work hours vs afterhours.

14. QUESTION: Please confirm that Note 17 under General Phasing Notes will limit the contractor to conducting and completing work in a single phase. All work must be completed in phase 1 before taking phase 2 etc.

ANSWER: All work in a single phase must be complete before proceeding to next phase.

15. QUESTION: Please confirm that the GC must directly subcontract the controls system integrator outside of the contract procuring the controls. So DIV 23 controls and DIV 25 BAS cannot be the same contractor

ANSWER: Div 23 and Div 25 are different controls contractors.

16. QUESTION: Please provide information on the existing Simplex Panel 4100U that is to be tied in to as well as the physical location.

ANSWER: Panel is located in Electrical Closet 4099; see Attachment #4. Verify feed location with fire alarm contractor.

17. QUESTION: Please provide floor plans with scale indicating runs of new CAT 6 cables. Detail 1 does not show scale or enough information to determine material needs.

ANSWER: Refer to drawings. Calculate based on distances shown.

18. QUESTION: On previous Legionella projects within GLAC the use of existing isolation valves at each of the risers/mains are a major concern. If the existing isolation valves do not hold at these locations is the VA/facility responsible for the means and methods to isolate branch lines? Would the VA like to place an allowance in the bid phase for freezing the lines or will there be a change order in order to replace existing valves and make them operable.

ANSWER: The contractor is responsible for isolating and draining. If the existing valve does not function, a change order should be submitted.

19. QUESTION: Please confirm the work hours for this project as some Legionella projects have been three shift capacity, while others are just day shift, plus night shift for shut-downs. Is there a general schedule depending on the phase or patient room type for this particular project?

ANSWER: No general schedule. Please see GI003, Construction Period Staging of Work - General Notes for typical after-hours work.

20. QUESTION: General Note 5. states that if awarded the contract, the contractor shall not be allowed any extra compensation by reason of any unforeseen difficulties or obstacles which eh bidder could have reasonably anticipated prior to bidding. Does the facility believe that the amount of piping off-sets installed throughout the project should be a condition that it should 'reasonably anticipate? Does the VA want the bidding SDVOSB to cover contingencies for inoperable valves and piping off-sets or will they consider that a change condition of the project? Did the A/E survey or estimate a number of off-sets that the construction team will encounter?

ANSWER: Add 50% for offset and contingencies and inoperable valves.

21. QUESTION: Note 10 states that demolition at exterior wall is limited to demolition necessary to perform patch and repair as specified elsewhere in the documents. Please confirm if the GC needs to paint just the portion of the wall approximately 12" around the cut and patched area or if the facility is expecting the GC to paint the entire wall affected by the patching.

ANSWER: Paint entire wall affected by the patching.

22. QUESTION: Per note 8 and 9 of the Protection Protocols please advise if EMS will provide the 'terminal cleaning' of the office in addition to the GC/Prime's commercially cleaned/construction cleaning prior to turn over to the end user.

ANSWER: EMS will provide terminal cleaning after each phase. Contractor is responsible for providing commercially clean environment prior to returning each space to the user.

23. QUESTION: Please confirm, as discussed in Protection Protocols note number 10 if the Prime's Infection Control enclosures, i.e. Edge Guard and other, are considered temporary protection and enclosures and are required to be taken down after each work day? There are phased areas of work per the ILSM where 'temporary construction' will need to take place in a particular area for 72-96 hours of continuous operations. It will take an additional two laborers to deconstruct the Infection Control Temporary enclosures on a project of this magnitude if required to be removed each night. Please offer expectations for the contractor.

ANSWER: The Infection Control enclosures (Edge Guard) are considered temporary construction barriers however, these barriers will not be taken down daily. Each phase of the project corresponds to a wing of the building and shall be isolated from occupied spaces using ICBs for the duration of each phase.

24. QUESTION: Where demo of gypsum ceiling is called per note #1, could access panels be installed as an alternative means and methods to patching and painting. GC would be at risk for fire rating of the panel per partition or ceiling location.

ANSWER: Patch and paint as required by construction documents.

25. QUESTION: Sprinkler head notes says to center the sprinkler heads. Please confirm that due to new ACT layout that the fire protection contractor shall modify the current system and reorganize the sprinkler heads for new ACT configuration.

ANSWER: Confirmed fire protection contractor to modify current system based on new ACT Configuration. Heads within same line of sight to line up within same detail.

26. QUESTION: The $2-5MM parameters do not seem to match the extent of this project. Does VA/GLAC have additional funding for this 3 year long project? Will there be a modification to change estimated value of construction?

ANSWER: No additional funding has been allocated. Parameters reflect entire cost of project as detailed in the design package.

27. QUESTION: Signage notes #1 states to remove all existing signs not removed during demolition salvage to VA. Please verify that the only signs going back in place as new, salvaged or otherwise are the are the 89 signs on the three signage schedules.

ANSWER: Confirmed only signs designated on Signage schedule are to be installed.

28. QUESTION: Per the Accessory and Equipment Schedule does the facility have a count of 'Typical Exam Room' vs. 'Typical Office Room' counts to verify our contractor installed requirements.

ANSWER: All rooms denoted as "exam room" will contain typical equipment for an exam room. All rooms denoted as "office" will contain typical equipment for an office. Location of equipment may vary, contractor refer to furniture plan for locations.

29. QUESTION: Does the VA have a cut sheet for the track, cubicle, with curtain A5180 JSN item in order to understand the labor necessary for installation. These are typical fairly elaborate tracking systems on ceilings. Does the VA have a quick sketch on whether the curtain track will be install as rounded or straight and the approximate LF of track per 'Exam Room' location. This installation has been done at other GLAC TJC correction projects typically sole sourced by the track manufacturer.

ANSWER: See detail 7/A502 for typical mounting detail. Curtain to be installed round. Approximately 8 LF per 'Exam Room'. Use InPro ClickEZE Optitrac or approved equal. VA to provide curtain.

30. QUESTION: In lieu of elevation details, will the GC provide the final ceiling at the same height prior to demo? This will help us deconflict interstitial/plenum space with our MEP contractors.

ANSWER: Refer to finish schedule for ceiling heights.

31. QUESTION: Per the 8-phase diagram; (a) will all typical office or space be vacated during the 120 days of construction? (b) Will employees be provided swing space or will the room occupants be provided off hour shift to accommodate construction. This answer helps us determine the detail of I.C. phase planning for this project.

ANSWER: All spaces within the construction area will be vacated for the duration of each phase. The construction area will be isolated from the adjacent spaces via ICB for the entire duration of each phase.

32. QUESTION: Please confirm the fire detection and fire alarm system manufacturer is for BLDG 228. This is for DIV 25 integration and for new construction.

ANSWER: Simplex is the fire alarm system manufacturer.

33. QUESTION: Is Chlorine Dioxide required for the crash cart system.

ANSWER: The emergency injection cart may use Chlorine or Chlorine Dioxide.

34. QUESTION (A/E AMENDMENT TO RFI RESPONSE): The city water entering the building is chlorinated and chlorine injection will be added to the hot and cold-water lines. As the water entering the building is chlorinated & chlorine injection is being used, the use of both free and total chlorine monitoring is redundant and not necessary. The RFI response states both are required which will add an unneeded expense as free and total chlorine measurements will be nearly equal. Are both required?

ANSWER: Only Free Chlorine is required to be monitored.

35. QUESTION: The specifications call for monthly service on the Water Quality Monitoring Equipment. Can you specify how many months of service should be included in the bids?

ANSWER: References to the monitoring of the equipment are for informational purposes only. The service portion of the design will be handled in a separate contract.

36. QUESTION: The city water entering the building is chlorinated and chlorine injection will be added to the hot and cold-water lines. As the water entering the building is chlorinated & chlorine injection is being used, the use of both free and total chlorine monitoring is redundant and not necessary. The RFI response states both are required which will add an unneeded expense as free and total chlorine measurements will be nearly equal. Are both required?

ANSWER: Free chlorine is gaseous chlorine and total chlorine includes free chlorine and hypochlorite. Both are required and are part of the engineered design.

37. QUESTION: Additionally, a UV treatment system is shown on the drawings but is not included in the specifications. With the planned chlorine injection systems, this is a unneeded expense. Is a UV treatment system required?

ANSWER: UV is a Hines VA requirement.

38. QUESTION: The specifications and design drawings are conflicting with respect to the emergency injection system. The specifications list an emergency chlorine dioxide injection cart and the drawings list a chlorine injection cart. As the building is chlorinated, a chlorine injection system would be recommended. Should an emergency chlorine dioxide or chlorine injection card be included in the bid?

ANSWER: The project includes an emergency chlorine injection cart and should be included in the bid.
