Codes and Standards: The Contractor shall follow all applicable codes and standards to this type of work including but not limited to Health Care System Memorandums (HCSM), OSHA Guidelines, NFPA 101, NFPA 70, Lock-out-Tag-out, and Rules of Station. ADENDUM- Pre-Construction Request for Information (PRFI): There are areas of the hospital that have been updated/remodeled since the issued date on the Contract Documents. Were the changes shown accounted for in the other projects? Please confirm and provide the areas that do not need to be addressed. Response: 5 East, 7 East, B-mod and 7F will not be a part of the solicitation. We can go over the drawings on a call to further inform you on these areas. Replacing the mixing valves in the showers will require demolition of the tile if there is not access from the backside. If the tile is discontinued and cannot be matched, what is the direction? Response: The intent on replacing the shower valves was to access from the backside without need for tile demolition. There are multiple foot pedal operated faucets throughout the hospital with the hot and cold stops located at the base of the wall. Will these require to be relocated higher or remain in the existing location? Relocating them will be much more intrusive. Please advise. Response: Existing stop locations to remain. BF118 - In the basement, there is a 3"" Hot water and 4"" Cold water shown for us to tie into for a bypass. We were unable to find these lines. Please advise. Response: Locate nearest minimum 2"" DCW/DHW riser serving area outside emergency wing for bypass. There are several locations throughout the building that have mop sinks that are not marked to have their faucets replaced. Should they be changed? Response: No faucets to be changed out for mop basins or HAC closest unless specifically shown on plans. What is the required flow rate of the branch line balancing valves? Should there be any balancing valves on the main lines? Response: Minimum branch flow rates to be 0.5 gpm. Overlapping work. There are several locations throughout the building where some of the work listed on these prints has already been done or is updated, i.e., new construction areas, ball type SOVs already installed where new ones are called out. Is the intent to carry on with the scope of the prints or will this need to be assessed as discovered for the duration of the project? Response: Refer to question 1. There are a few locations where there are existing sinks that are not called out for any changes to be made that don t seem to have been updated recently or aren t shown on the prints at all. Do these need to have new faucets/mixing valves added? Some are mop/service sinks. Response: No faucets to be changed out for mop basins or HAC closest unless specifically shown on plans. BF144C sink is called out for new faucet and mixing valve with keyed note 2 on sheet M201. Sinks/Lav off hallway C4B4 callout out for new faucets and mixing valves with keyed note 1 on sheet M702. On the Dead Leg at this location, should the new shutoff valve for future use be installed in the hallway instead of in the electrical closet? This would leave the dead leg longer than six inches as noted in Note 6 this page but would be a better placement of the valve since the facility plumbers don t have access to the electrical closet on their own without calling another department to come and open the door, as witnessed during our walk through. Also, it just seems like bad practice to have a water valve in an electrical closet. Response: There is already existing piping and valves located above the electrical closet. Per the scope, the dead leg must remove back to 6"" or less in length. The dead leg is to be removed back above the electrical closet and valved for future. Throughout the facility there are some locations where the shutoff valves installed are Gate type and they re not called out on the print to add new SOVs, as these are prone to failure with age, if they haven't already, do we need to install new Ball Valves down stream of existing shutoffs? Some of these will probably end up having to be changed out during this project anyway out of necessity to facilitate our work due to valve failure. Would make progress timelier to have this planned for ahead of time. Response: Yes, install new ball valve s downstream of existing shutoffs. Non-Keyed note says ""Add Re-circulation to Hot Water"" but does not have lines drawn to where it is to go to. This is the only one in the whole print set labeled this way and wanted to clarify there wasn't a different intention than the others. Response: Add new 1/2"" DHWR to existing DHW serving sink in 8B101 and connect to new DHWR piping in hallway C8B4 outside room 8B105. In the Northwest corner of south end of the first floor, all the ""new hot water return lines"" are tying back into the hot water supply in this area. This doesn t provide a way for there to be constant circulation of the system. which means all the water in this section of piping will eventually cool down into the temperature range where legionella grows, defeating the purpose of the project at large. There are more locations like this throughout the project. Recommend running a new dedicated return line to tie into. Response: These return lines are intended to tie back the hot water supply mains that are constantly being circulated. 8th Floor North, psych ward. This wing appears to be an anti-ligature wing with all anti ligature fixtures. If the intent is to keep this wing anti ligature, none of the scheduled replacement parts meet an anti-ligature standard. Verify if this is to remain anti ligature or not. If so, we will need a different basis for design for faucets, shower valves, etc. Response: Yes, A/E to provide different basis of design. There are 16 locations where the under-sink mixing valve is called out that aren't traditional sinks. The faucets are wall mounted mop sink style faucets for floor wash down. Mixing valves for these would need to be piped in above ceiling. Are the mixing valves still required in these locations for this type of faucet? Response: Install new mixing valve above ceiling at piping serving wall mounted faucets. In Room GR106, the Heat exchangers are too tall for the room with all the other systems there that are to remain. Suggest moving the new heat exchangers to GR100. This would also allow the new pumps to be installed in GR106 instead of GR107, thus leaving the existing storage room intact and available. Response: A/E advises moving the heat exchangers to storage GR107 instead of GR100 to minimize re-piping length. The new pumps could then be installed in GR106. COR to provide insight as well. In room Bf 155, can we move the Glycol tank in this room to the back end of the mechanical room under the air separator and re pipe it, to help accommodate the larger footprint of the new heat exchanger and piping where the current heat exchanger is sitting. Response: A/E does not take exception to moving the existing glycol tank to help make room for heat exchanger in BF155. What are the ICRA requirements for this project, primarily associated with #5 on the SOW? Response: ICRA will vary based on how invasive the work in an area will be. Most will be class II or class III. Phasing - In reference to #5 on the SOW, how many rooms will we be given access to at a particular time? Response: OKC VAMC will provide as many rooms as the contractor can handle for a standard workday. Details 3 and 4 on M203 show the new equipment (HEX 2, HEX3, P5, P6, P7, S2) to be in the same location of the existing equipment, on the back wall behind the piping, not accessible for maintenance in the future. It is recommended to move the equipment to the front, more accessible for the end user. Response: A/E does not take exception to installing the heat exchangers in front of the piping for accessibility. There is a steam line and a condensate line that are dead ended above the lobby in front of the elevators on the ground floor. The lines will be cut off during a steam outage we need to do for HEX 2 & 3. Do the deadlines need to be reconnected or can they be completely abandoned and removed? Response: Leave lines dead and remove to help clean up space. The plumbing fixture schedule shows the specific model number for the shower valve but doesn't say anything about the shower head. Just want to clarify that we are to change out the shower heads and not keep the old ones in place. If we are to replace the old shower heads with new ones, please provide style wanted for regular and anti-ligature. Response: Shower heads not intended to be replaced, only the shower valve. The eyewash stations in building 19 are all already supplied by the mixing valves for the emergency showers in the same rooms. Was the intent to just add a mixing valve to these lines where it was thought that there wasn't one? Or was the intent to shorten up the piping length and available area for legionella to grow? Response: Intent was to add a mixing valve where it was thought there wasn't one. If eyewash is already served by tempered water, then another mixing valve is not required. Please provide an equipment schedule identifying the model # and quantity of Phigenics equipment to be installed. Schedule should reference room # and provide a list of water monitoring parameters to be measured at each location. It should identify if the equipment is connected to domestic cold water or hot water. Is sheet E1300, dated 6-15-2020 included in the bid documents? Response: This sheet indicates to have the information requested. Period of Performance: Anticipated length of Construction is 240 days with 1 month for solicitation of construction contractor.
