44. Q. Specification 23 50 1; Specification 23 50 11, page 26, 2.7 Fuel Oil Pumping

Equipment, A. ‘Oil pump and motor assembly shall be factory assembled in an epoxy-enamel coated carbon steel waterproof enclosure with external threaded connections for pump suction and discharge...’

Page 28. F. ‘Pumps, motors, valves, piping and accessories shall be furnished as a factory-built unit. All items of equipment shall be mounted.a steel drip pan base with an area sufficient to extend beyond the limits of all equipment…’. These are conflicting statements. Which is correct?

A. Article 2.7.A applies to the temporary pump skid serving portable boilers. Article

2.7.F. applies to permanent pumps 14-FOPS1. In article 2.7.A, revise “(for below grade installation)” to “(for temporary pump skid serving portable boilers)”. In article 2.7.F, add tag to read “Arrangement (14-FOPS1 Pump Set)”.

45. Q. Drawing MP7.03; Drawing MP7.03 shows the back-pressure regulator appropriately placed in the fuel oil system. There appears to be an additional pressure device with 3-valve bypass at the discharge of the pump set. Please provide clarification as to what this is and its purpose.

A. The indicated valve is a pressure relief bypass.

46. Q. Drawing MP403, D3; Specification 23 50 11; The flash tank detailed on MP403, D3 is not indicated on the Mechanical Schedules.

Additionally, Specification 23 50 11, page 26, 2.6 Flash Tank, C, 7. Condensate Pipe: Provided perforated schedule 80 steel pipe inside tank as shown. No condensate pipe is shown on detail D3, MP403. Does this exist?

A. Correct, there is no flash tank schedule. Provide flash tank in accordance with the dimensions on D3/MP403. Provide perforated condensate inside tank as specified. This pipe is typically available from tank manufacturers and extends approximately half way into the length of the tank.

47. Q. Page "10 of 181" & "Page 80 of 181"; The solicitation states that "Offers are required to submit an original and five (5) copies plus five (5) CDs of the technical evaluation factors/responses spiral bound (no 3 ring binders)…"

As the printing and assembly process of proposals usually comes down to the wire, we request that the VA please allow 3-ring binders for ease of assembly. Spiral binding our proposal will require us to outsource our printing/assembling needs.

A. Absolutely no 3-ring binders are allowed. You will be considered non-responsive.

48. Q. Page "91 of 181"; Factor 2 - Past Performance; In lieu of Past Performance

Questionnaires, we ask the VA to please allow the submission of CPARS evaluations. Main points of contact for several of relevant, recent projects (as outlined as acceptable in the solicitation requirements) have retired or are no longer employed by the VA; obtaining completed PPQs from these individuals will be a challenge.

A. No

49. Q. Project Duration; The solicitation indicates the Contractor shall complete the Project within (1200) calendar days after receiving notice to proceed.

Section 01 32 16.15 1.5.A “The Complete Project Schedule Submittal” states “…The final Project Schedule in its original form shall contain no contract changes or delays which may have been incurred during the final network diagram development period and shall reflect the entire contract duration as defined in the bid documents”.

The solicitation (page 94 of 181),“Short Schedules”, states the offeror must provide for completion within the time frame (number of days after receipt of the Notice to Proceed). The maximum anticipated days of completion for this project is indicated on the Standard Form 1442. This duration shall establish the contract completion date. Short schedules will not be accepted. Critical path activity durations shall total the number of days indicated on Standard Form 1442”.

Drawing Number GI702 indicates Phase 2 Duration of one (1) Year (365) calendar days. Since “short schedules” are not allowed and the Government owns all the float (i.e. Contractor has no chance for equitable adjustment based on potential Government delays), does the Contractor need to carry labor, travel, general conditions and indirect overhead costs for a period of (1200) calendar days? This will result in substantial costs. Based on the Phase 2 Duration (i.e. 365 calendar days) the (1200) calendar days is unrealistic (too long) and will result in inflated costs to the Government. Request duration is reduced to (730) calendar days.

A. Revised Period of Performance reduced to 1,095 days.

50. Q. Factor 1B "Project Personnel Experience" requires biographical data for seven (7) different personnel. The Specifications do not outline that a dedicated SSHO or QA/QC Specialist is required on this Project. Specifically, there is no QA/QC specification.

Please confirm the Project Superintendent can serve all three (3) roles on-site, and the Contractor is only required to have one (1) full-time person on-site (i.e. the Project Superintendent).

A. Yes. One person can serve as the SSHO& QA/QC roles as well as the Site Superintendent.

51. Q. Specification 23 50 11, Page 22, Section 2.3; The blowdown tank Specification 23

50 11 and the scheduled Blowdown Separator Schedule on Drawing MP601 are inconsistent.

The Specification calls for the, "blowdown tank volume to be twice the volume of a 4" blowoff from the largest boiler connected to the tank." Schedule depicts the blowdown separator to be 1'-8" diameter x 6'-5" length. The Specification calls for a 40 PSIG ASME Vessel, and the Schedule shows a 150 PSIG MAWP pressure rating. Please clarify which is correct.

A. Provide blowdown tank as scheduled. Disregard the last sentence of article

2.3.A: “Tank volume shall be twice the volume of a 100 mm (4 inch) blowoff (reduction in boiler water level) from the largest boiler connected to the tank.” In article 2.3.C.3., revise design tank working pressure from 40 psig to 150 psig.

52. Q. Drawing MP705, Detail D3; Indicates the requirement for Opacity Monitors, however 230911 2.8 states that Opacity Monitors are "not used". Please advise if Opacity Monitors are required and if so, please provide a spec. If Opacity Monitors are required to be outdoors based on installation requirements, please outline NEMA rating and outdoor requirements.

A. Disregard opacity monitor on detail D3/MP705.
