D4030

RFP Section D4030 indicates that a standpipe must be provided where required by UFC 3-600-

01. The wording in UFC 3-600-01 section 9-

10.2.2 is open to two different interpretations. We read that section to indicate that as long as every portion of the facility can be reached within 450 feet from an exterior door that a standpipe is not required. From a fire protection engineering standpoint this makes logical sense. This is consistent with interpretations on other projects (but can be read to have two opposite meanings).

Please confirm that this is the Government’s interpretation as well since this has significant cost implications.

Please confirm designs shall confirm to UFC 1-200-02 and no specific information in the replaced (“cancelled”) UFC needs to be considered.

See

205 380 ESR D30

ESR D30 – page 380 Ventilation Systems – this section required that each Room Plan be provided with a minimum of 40 CFM of ventilation air, and that ventilation (OA) to the building is to exceed exhaust air by a minimum of 15%.

Current UFC 3-410-01 (w/Change 4 dated 01- November 2017) required that DOAS air inlets and outlets must deliver airflow quantities equal to or greater than 50 cfm to allow for proper system balancing. If living quarter toilet/shower room exhaust is therefore required to be 50 cfm (per the UFC) and ventilation 15% greater (57.5 cfm) this is 44% greater ventilation rates that indicated in the RFP. ASHRAE Standard 62.1 – 2013 & 2016 would require only 32 cfm outside air (based on double occupancy, 355 sqft area) and 25 cfm exhaust (based on continuous exhaust). Thus to comply with ASHRAE for 127 guest rooms a total ventilation rate of 4,064 OA / 3175 exhaust. UFC compliance would require

57.5 x 127 = 7300 cfm OA / 6350 exhaust (180% of the ASHRAE requirement); RFP 40 cfm OA / 35 cfm exhaust = 5080 OA/4,445 exhaust (125% of ASHRAE requirement). With the treatment of outdoor air being a significant operational energy cost – please confirm if the RFP minimum 40 cfm ventilation per room will be permitted in lieu of the current UFC requirement.

ESR D30 – Page 377 1st Paragraph & Page 378 – 4th Paragraph. The paragraph on the first page says to “Consider” providing heat recovery from chiller to domestic hot water system, while the paragraph on page 378 states simply to “Provide heat energy recovery from the chiller to the domestic hot water system” – is this system required, or only an option to consider in order to achieve the energy goals if necessary and LCCA effective?

See Amendment

207 378 ESR D30 2 & 3

ESR D30 Page 378 paragraphs 2 & 3: These paragraphs appear to require an HVAC system consisting of Air Cooled Chiller, hydronic heating and VAV with Fan powered terminal units, however page 379 implies that other system options are acceptable pending LCCA (VAV, GSHP & WSHP). Please confirm that any of the 3 systems listed on page 379 are acceptable if supported by LCCA.

See

208 387 ESR D30 2nd

ESR D303001 Chilled Water Systems: This paragraph requires primary/secondary pumping of the chilled water system while the “VAV Systems” under D30 system description (LCC optional system choices) allows for either Primary / Secondary OR constant flow pumping.

Based on this system option only serving a very limited quantity of coils (AHU’s and DOAS) – it may be more economical and energy efficiency to use constant volume pumping with 3 way valves on the limited quantity of chilled water coils.

Please confirm constant flow pumping is an acceptable alternative as indicated in the LCCA systems option descriptions.

ESR D30 Page 378/79 requires the LCCA evaluation of “Three general HVAC system types and two heat distribution systems”. The three alternative general HVAC systems are described however section D3020 Heat Generating Systems requires boiler heating (hydronic heating) – please clarify what are the two types of heat distribution systems that are to be evaluated?

211 378 ESR D30 4th

This paragraph requires that the DOAS system be “designed to provide 100% design capacity in the event of a failure of the heat wheel” – if LCCA alternative #1 is chosen this may be feasible through sizing through oversizing/selection of the cooling coil to account for wheel failure. If using the GSHP or WSHP LCCA alternatives the DOAS will utilize a condenser water to air DX cooling coil as part of a packaged DOAS system from a manufacturer. Equipment with oversized cooling capacity to account for failure of the enthalpy wheel is not available, nor would it be efficient due to excessive oversizing when wheel is operating as the DOAS unit is intended. As alarms to the DDC system will be provided for failure of the DOAS unit – is this wheel failure requirement necessary, particularly if a GSHP or WSHP system is pursued?

See Amendment

212 379/80 ESR D30

The DOAS system requirements for both the GSHP and WSHP DOAS LCCA alternatives require that the DOAS systems supporting these design alternatives utilize “hot water heating, pre-heat and reheat using hot water”. As the DOAS units for these LCCA alternatives will be heat pump type is hot water heat still required? When the unit requires heating, the heat pump will operate in a heating mode, and when cooling/dehumidification is required – hot gas reheat from the refrigeration cycle should be used to reheat to room neutral delivery temperatures without having to energize boilers and expend energy.

213 389 ESR D30 4th

Paragraph states to “Provide all piping with cellular glass or polyisocyanurate insulation” ….

And then says “for closed condenser water piping provide fully insulated High Density Polyethylene Pipe (HDPE). PVC or CPVC must not be used. No deviations will be allowed.” Is the HDPE intended for outdoor and or geothermal well piping - or is this the requirement for indoor condenser water distribution piping also? Additionally UFGS 23 07 00 INSULATION SYSTEMS, editors notes allow for the omission of insulation on piping where there is no risk of condensation. If WSHP loop piping is maintained within temperature ranges such that condensation will not occur, is insulation on such piping required? It would be more energy advantageous to not insulate WSHP loop piping provided it is maintained such that condensation will not occur.

Chapter 6, Section G40 Site Electrical Utilities System

Descripti on

First paragraph of Amendment 5 states:“Naval Weapons Station Yorktown is supplied electrical power from Dominion Virginia Power by two overhead 13.2 KV, 3 phase, 4 wire feeders which enter the base and pass thru the worksite prior to looping thru the Naval Weapons Station. This project will require demolition and/or replacement of tap feeders from the west feeder.

The west feeder routes through the area of the Parade Ground and future BEQ’s as shown in Part 6 Attachments (General Site Information), Overall Site Concept Plan, therefore, will be relocated as indicated in Part 3A, G40 of this RFP. See Existing Electrical Site Plan in Part 6 Attachments (Electrical) of this RFP.”

See Amendment

1) The route described for the Dominion Virginia Power overhead 13.2kV line running through the new BEQ and parade site does not match what is shown in Google earth views. Google shows an overhead power line running along the east boundary of the site and connecting to overhead lines along Shupper Drive to the south of the site, which corresponds to what is shown on drawing CU103 Utility Plan – Parade Ground of Attachment 6C of the RFP.

See

2) Paragraph goes on to say that a drawing, part of Attachment 6C, Overall Site Concept Plan, shows additional info on this overhead line running through the site. Please indicate what drawing number this sheet has, as I cannot find it in the Attachment 6C drawings.

See Amendment

3) Paragraph also states to see Part 3A, G40 for additional info on relocated overhead 13.2kV line, and to see existing electrical site plan. First, G40 is in Part 6, not 3A, and amended G40 does not give any further direction on relocating this line. Second, the reference is made to the existing site electrical plan, I can find no site electrical plans in the attachment 6C drawings, they are all Civil drawings. Please provide this/these electrical drawings.

225 D503005

D503005 contains conflicting statements regarding the Electronic Security System. It states first to provide raceways and supporting structures for ESS provided and installed by the ESS supplier (like that is someone the base hires directly); then it states later to provide a complete ESS including all equipment, testing, etc. This includes ACS, IDS and CCTV so it will be a sizeable number. Please confirm if the contractor should be carrying the coat of the actual wiring, equipment, monitors, testing, etc. or just the raceways and power connections for the equipment.
