1. QUESTION: Please clarify the scope of work limitation which indicates that small portions (1400 sf max) of the hospital are to be affected at a time. Is the intent to setup temporary barriers to secure up to 1400sf of space, perform all demolition of mech systems, install new, provide power, and complete work in that 1400sf area, prior to moving on to the next area? If so, I want to confirm that based on the roughly 65,000sf of ACT ceilings to be removed for performance of the work, this will result in at least 47 phases of construction (if each area can be exactly

1400sf). Backing out 2 months for submittals and mobilization, the 540‐calendar day duration provides for about 2 weeks per phase. Please confirm that this understanding/analysis is correct.

ANSWER: Each phase will encompass VAVs associated with one air handler.

2. QUESTION: Please clarify if any new concrete pads are required for new mechanical equipment.

These do not appear to be called out or detailed in the drawings.

ANSWER: Existing pads are to be used for equipment being replaced. New pads are required for new equipment.

3. QUESTION: Please clarify where the spec sections for Structural Steel, Metal Stairs and Pipe

Rails apply on the project.

ANSWER: These spec sections apply to the boiler platform.

4. QUESTION: Electrical demo drawings call for many devices/lights to be “protect(ed) and secure in place during demolition”. The associated notes on the new work electrical drawings indicate to “install existing device in ceiling…”. Please clarify if the intent is to protect in place or remove and reinstall. Or, is this up to the contractor to decide/perform as needed?

ANSWER: The Contractor must clean all devices/fixtures and protect them during demolition as close to their original position in ceiling grid as possible. After ceiling is replaced, contractor must reinstall each device/fixture in its original position.

5. QUESTION: Electrical demolition notes numbers 5, 9, 12 & 13 indicate to “coordinate with contracting officer to remove”. Is the removal to be handled by the contracting officer/hospital staff, or by the electrical contractor?

ANSWER: The coordination requirement is for scheduling only. All removal of devices and supporting material must be performed by the contractor.

6. QUESTION: Please clarify where negative air machines are to be exhausted to in areas of work that are not near exterior openings?

ANSWER: All phases will required their own ICRA/PCRA. Per note 6 on ceiling plans, exhausted air is to pass through HEPA filters before being introduced into adjacent areas.

7. QUESTION: One of the crawl space entrances is located in mechanical room 134 which is identified as a Bio Hazard room and is not listed as one of the locations to be under construction. The access is through the floor and there wouldn’t be any way to get the piping into the crawl space without cutting it into 5 ft. pieces. Can holes be cut into the exterior crawl space wall to access the crawl space in multiple locations?

ANSWER: Access to crawl space from 134 does not access crawl space where work is occurring.

There is access to the crawl space in Elevator Equipment Room C012 in Area D1.

8. QUESTION: On plan sheet MP100‐A1 thru MP100‐G2 under key notes, NOTE 2 state to install drain pan under piping. Then there is an asterisk that states “notes above not indicated on all drawings”.

Answer: The new and existing ductwork is shown on the plans.

c. Will the insulation need to be removed from the existing duct prior to testing?

Answer: No.

10. QUESTION: SPEC SECTION 01 14 00 SPECIAL SECHEDULING, ITEM 4 states that 1400 SF is the maximum space that can be worked on at one time and that beneficial occupation must be performed prior to moving to the next location. When it comes to TAB of the water and air this will be an issue as the settings will continue to change as the work progresses. Is it the intent of the contract documents to TAB each section as we complete it?

ANSWER: The TAB will be completed at the end of the project.

11. QUESTION: Due to the amount of areas we will have to work in doing a maximum of 1400 sf, there will be 60+ mobilizations with walls that will need to be erected and removed. We request more time be added to the contract for phasing and believe that an additional 740 days will be required to complete the project on time.

a. Can the contract duration be extended?

Answer: No.

12. QUESTION: PLAN SHEET M‐504 shows three (3) different types of temporary wall details. The plans do not indicate which type of wall is to be used at what locations. Please review and advise.
