QUESTIONS WITH GOVERNMENT PROVIDED ANSWERSWe would need to know the downstream pressure with maximum gas flow – approximately 8200 CFH.? Normally we provide the filter and regulator on VA jobs.? We need to know the pressure in either case. We assume the vendor is talking about gas downstream pressure, but downstream of what? The existing regulators? The downstream pressure would need to match whatever is required by the burner manufacturer, it shouldn’t matter what we have today. Do they mean our upstream/supply pressure into the building? Gas pressure coming into the building appears to be 10 psi. ?Note 1A on the schedule indicated normal oil pressure to the Burner of 40 PSIG.? The Boilers require oil at 80-100 PSIG.? If we provided the oil pumps they would be rated at about 120 GPH each.? The burn rate is about half that but we need to allow for recirculation.? If the existing pumps can provide oil at this pressure and capacity (per Boiler), we do not need to provide oil pumps with the Boilers.? Otherwise, they are required, can you clarify?Please supply new oil pumps that meet the requirements of all boilers. The 80-100 PSIG plant air atomization pressure is adequate; however, the spec calls for an air compressor furnished with the Burner, and the oil schematic shows it as optional.? We can provide one or the other, or both, if desired.? Please include a new plant air compressor that meets the pressure and capacity requirements for all boilers. The solicitation says the due date/time is 31 May 19 @ 1400.? The pre-sol and the FBO posting indicate the due date is 12 Jul 19.? We believe the actual due date/time is as stated in the solicitation but would like your confirmation. It is due on the date the solicitation states.? The pre-solicitation notice is just a guess on when we may post the actual solicitation.Reference solicitation page 5 of 53, paragraph 6a. and 6.b., and page 7 of 53, Volume II - General Offer and Price Proposal, paragraphs i. and ii.:? These paragraphs in the first reference give very specific guidance on how to format the entire proposal.? The paragraphs in the second reference are very similar, but not the same.? Can you please indicate which reference takes precedence? The two sections should offer the same guidance.? Please indicate what you need clarification on specifically and we will clarify. We recommend giving everything that is requested, no matter what paragraph it is located in.Reference solicitation page 7 of 53, Volume II - General Offer and Price Proposal, paragraphs iii. and vi.:? Can you please clarify the difference for these two points of contact? They reference the same individual.Reference solicitation page 6/7 of 53, Volume I - Technical Proposal, paragraph b.iii. and pages 7 & 8, Volume I – Technical Evaluation Factors:? The first reference specifies we must submit “Past Performance of the Prime Contractor” and we are provided with a Past Performance Questionnaire, but the evaluation factors do not include an evaluation of past performance.? Can you please clarify if we are to provide PPQs? As stated on page 9 of 53 of the solicitation, past performance and EMR will be reviewed and ratings assigned to determine if a vendor is responsible prior to award.?This is not an evaluation factor. Reference solicitation page 8 of 53, Factor 2:? Project Schedule, 3rd bullet:? How do you want us to indicate on the schedule if work is being self-performed or subcontracted?? Further, knowing the particular subcontractor that will perform the subcontracted work is not typically known until the very last moment.? Inclusion of the specific subcontractors in both the hard copy and electronic copy will be very difficult, at best.? Can you eliminate both the requirement to identify the subcontracted work on the schedule and the requirement it identify specific subcontractors’ names? The Government does require to know in advance who the subcontractors are. ???Reference solicitation, page 1, SF 1442, Block 13.a and 36C26319R0078-004.docx (Past Performance Questionnaire), page 1, Instructions to Reference Contact:? The proposal due date in the first reference is established as 5/31/19 while the second reference states that the PPQs are to be returned by 6/26/19.? Can you please clarify the requirements for the PPQs? Questionnaires should have stated they are due by 5/31/19 (the same as when the proposal is due). However, amendment A0001 was posted that extended the due date to June 11, 2019 at 4pm CT. That is also when the questionnaires will be extended to.Can you tell me if there is a preferred burner control package for this project????? The existing burner control package on the new boiler (Boiler #1) is by ‘Preferred Utilities’ out of New Jersey.? The technician for this boiler must come from Connecticut to service it. ?Would prefer local technicians as much as possible or integrated burner packages direct from the boiler manufacturer. Also, what are we going to do about port-o-potties for this project?? Will the contractor be required to provide any? ?Typically so.? I did not see this language in the drawing reviews or the specs. ?The boiler plant only has one bathroom and I do not think the workers want to share it with ‘strangers.’Contractor to provide. 7M501 | Please advise on which manufacturer was used as the basis of design boiler.

Not knowing the existing structural constraints, can the government provide guidance for temp shoring.The Government isn’t sure what additional shoring is being referred to in the question. The Government personnel have no recollection of this conversation during the site visit. ?7A101 | Demolition of existing control and various devices. Typically there are additional monitoring points/alarms from the hospital (Medical Gas Alarm, O2 Tank, etc.) that come back to the boiler plant. These alarms are not listed on the drawing package. Can the government confirm if any additional alarms will have to be removed and re-installed other than the few shown on the drawings?No additional. Section 23 09 11, pg 1, pp1.1.D specifies “Provide new boiler plant control system to manage boiler lead/lag operations.”, but further section 2.2.A.4.c on page 10, specifies that “VA boiler Plants PROHIBIT any boiler to automatically or remotely started and lead lag control systems are prohibited within VA boiler plants….”.? Additionally VA Directive 1810 also prohibits the use of boiler lead/lag control in VA plants.? Please confirm intent on 23 09 11, pp 1.1.D and that Lead/Lag control is not required. No lead/lag control for work station; starting of boilers is manual at each boiler panel.Section 23 09 11 specifies new boilers 2 & 3, and existing boiler #1 controls are to be connected to the existing JCI Boiler Plant Control station using BACnet MS/TP via new computer workstation.? Can you provide information such as manufacturer, model, and communication protocols available of Existing boiler #1 controls that will need to be integrated?Please see updated Spec Section 23 09 11Computer workstation section of 23 09 11, pg 34, pp 2.5.B.2 specifies Intel Xeon processor.? The Xeon processor is a “Server” class processor and does not perform well in the graphics intensive environment of the SCADA workstation.? The Intel core i7 is better suited to this environment with higher clock speeds.? Most SCADA software packages such as Wonderware & GE Cimplicity only utilize 1-2 processor cores which makes the i7 a better choice.? Will a workstation utilizing the i7 processor be acceptable?Delete languageDevices/signals listed in spec 23 09 11, section 2.5.C.18.a, & b list signals from boiler mounted devices that are not listed on a drawing schedule or boiler points list.?

Is it the intent of this project to add a HMI touchscreen to an existing Mater Control panel, or will a new Mater Control Panel be required?NoDevices and signals listed in Spec 23 09 11, section 2.5.C.20.d.1-thru 21 contain alarms that typically would be wired a master control panel for monitoring and alarming, by the computer workstation, including but not limited to high and low Natural Gas header pressure, High and low steam header pressure.? Are these signals present in an existing Plant Master system, or will a new Plant Master System be required to be supplied?Revised in 23 09 11 re-issue. Section 2.15 “Boiler Plant Building Dangerous Gas Detection System” of specification 23 09 11, item A. states “Gas detection panel existing and does not have capability for remote alarm status to a computer workstation.? Interface is not required to computer workstation.”.? This statement is in conflict with item 2.5.C.20.d.17 which requires alarm points in computer workstation for Carbon Monoxide (CO) or combustible gas in building.? Which one takes precedence???? Clarified on addendum; no gas detection interface to work stationStatement of work item 1.1.6 states “Include steam meter, water meter, and natural gas meter for each new boiler. Meters shall interface with the existing Johnson Control Metasys EMCS. The capability to totalize and store data points for each of the meters is required.”? Specification section 23 09 11 pp2.7 “Flow Meters” only require the vortex meters (Steam Flow) to have BACnet communications for connection to Johnson Controls Metasys control system.? Water Flow Meters, Fuel Oil Meters, and Turbine are only specified to communication with the computer workstation (SCADA system).? Please clarify which takes precedence, Statement of work, or the written specification.Follow the specifications.Spec Section 23 09 11, paragraph 2.1.J, defines the spare parts requirements but lists master control pressure transmitter as spare.? Section 23 09 11-pg16, paragraph 2.1.K. also defines master control. Is master control a requirement and are master steam pressure transmitters required?Yes, it is required. On drawing 7M501 under Steam & Gas Flow Transmitter, Element Schedule, it is listed as Boiler 1 existing Gas flow meter is Thermal Mass flow technology, but new flow meters to be supplied for Boilers 2 & 3 gas flow are to be turbine type.? Mixing technologies does not allow for equal comparison between boilers and may causing efficiency readings using these comparisons to not be accurate.? Please Clarify if Thermal Mass Flow meters for Boilers 2 & 3 will be required in place of turbine meters. Clarified on the addendum; turbine meters per VA standardsSpecification section 23 09 11, pp 2.5.C.18.b. & pp 2.5.C.20.d lists signals and alarms to be displayed on SCADA workstation, but are not listed in project.? These signals include, DA Tank Level, Condensate Tank Level, Pumps in Operation, Chemical feeders in operation, feed water deaerator steam pressure, natural gas header pressure, & Boiler feed water header pressure.? Section 2.5.D further states to provide as necessary to satisfy programming requirements.? Do these transmitters exist and are they wired into an existing control that can be monitored by the SCADA, or will the transmitters and monitoring control be required to be supplied?Clarified on the addendum ................
