| RFI |
| Response |
| 1. In regards to drawing HA-01 the Project title on the drawing is Building 1 Halls and Walls. I do see it has in red on the top left for Reference Only. |
| This is for reference but as this project includes demolition of Vending room, the walls right outside that would be lead containing if it is a yellow glazed block. |
| 2. On Drawing G-003 Under Life Safety General Notes, Note A indicates referencing drawing GI002 which is not included with the contract documents. |
| This is assuming GI002 is a typo and that it was suppose to be G-002 in which G-002 does speak on ICRA and life safety. |
| 3. Drawing A-101 please clarify the building numbers on the drawings. Some Reference Bldg 1 some reference Bldg 18. Drawing FX101 References the switchgear Rm as Building One. |
| Building 1 is the hospital itself. Building 18 is the switchgear room. These two rooms are connected but separated by a wall. For this project, we will be taking down that wall and incorporate the vending room (in Building 1) as part of the switchgear room (building 18). |
| 4. Is Building One and Building 18 the same building? |
| See question # 3 for explanation. |
| Drawing MH101, Could you provide the approximate physical distance from the Cooling units in the Switchgear Room to the condensing units on the roof. |
| Bidders should make reasonable assumptions based on the documents provided and include sufficient allowance in their bid to accommodate typical conditions. |

| No equipment is being sole sourced. Approved equals are acceptable. |
| 1. Will all the work for this project take place during normal work hours? All work should take place during normal work hours. |
| Work that may need be outside of working hours will need to be coordinated with the COR. This is usually not an issue unless the GC wants to complete this project all at night. Outages will be done outside of working hours but coordination will still need to be completed. Section 01000 subsection 1.25 and Section 010000 subsection 1.6.2 |
| 2. Does the Superintendent have to be an employee of GC? |
| No, but all qualification must be met as seen in the specs. This superintendent will still be viewed as an extension of the GC by default an employee of the GC. This superintendent will be dedicated only to this project and no others. 010000 sub 1.30.B / 014500.10 sub1.5.1.2 / 014500.10 sub 1.6.1 |
| 3. Can Superintendent or SSHO have more than one duty? |
| Superintendent and SSHO are two different individuals with two different roles. We will usually allow QCM/superintendent to the the same person given qualifications are met for both. Section 013526 subsection 1.7/ Section 014500.10 subsection 1.5.1.2 |
| 1) Please clarify if a superintendent can be a dual hat to cover the requirements of SSHO? |
