"Standard Form 1442" item 11, which states "The

Contractor shall begin performance within 15 calendar days and complete it within 1,700 dalendar days after receiving award." Please clarify which contract duration is correct.

Booth in Bldg. 96

14 9/25/2018 The Solicitation, Offer, and Award, Section 11 identifies the contract duration as 1700 days from award. Factor

2 (i) identifies the contract duration as 1700 calendar days and identifies an anticipated award date of

12/31/18. This would result in a CCD of 8/27/23. The phasing schedule provided in Additional Information (c) on page 31 of 67 of the Solicitation identifies an 8/2/23 start for Phase 7 with a 117 day duration. This would result in Phase 7 completion by 11/27/23. Please confirm the correct contract duration and phasing schedule.

The phasing schedule provided is an approximation - NAVFAC will evaluate non-price factors including "Factor 2 –

Management Approach and

Schedule"; "project schedule shall illustrate the offeror’s ability to achieve or improve on the contract completion date set out in the RFP

(1,765 calendar days)."

Specification Statement: “The paint booth will have a makeup air unit sized to dehumidify and heat the outside air to summer and winter environmental conditions list in Table 1. The make up air unit will be supplied with a dedicated chilled water system.” We assume this requires the equipment vendor to supply the chiller, pumps and associated controls. This will likely require approx. 700-ton chiller. This is larger than any packaged unit, and will require a water-cooled chiller and a cooling tower (air-cooled is doable, but would be very large).

The chiller system will feed MAU, but is a separate system specified in section 23 64 10. This is CLIN 0002B-

13 per section 00 22 13.00 20, Page 5.

However, Drawing M-102 and M-103 show the dust collectors outside the building. Please clarify.

Yes , Building 404 has Dust Collectors located outside. The foot print limitations inside (between booths) are for the media recovery equipment. Contractor will provide general arrangement submittals.

Seismic statements: "The paint booth shall stand by its own structural support and comply with ASCE 7-10 seismic design requirements". Also stated that this facility is a Risk Category IV, which is the most critical type of facility. There are generally two levels of seismic requirement - the first requires equipment to remain structurally sound in a seismic event but doesn't need to remain operational, the second requires equipment to remain structurally sound AND must be able to continue to operate. Risk category IV would indicate that we need to continue operation after a seismic event. We'll need to better understand these requirements, as this can mean very different values for engineering and equipment costs. We are expecting all booth structures and equipment must be engineered to meet this requirement. Especially with the MAUs and

Large Dust Collectors of the roof.

Seismic parameters in section 2.2 should be updated to:

Consolidating and upgrading blasting operations is an excellent opportunity to standardize on replacement components. It is encouraging to see amendments that define exactly what the customer wants. The

'Thompson valve" is a good start. Would more replacement components be considered, i.e. Screw augers - motor /gear boxes, stub shafts, end bearings, hanger bearings. Elevators - motor / gearboxes, head and boot pulleys, belts, buckets. Blast pots - donuts / pop up, combo valves, deadman, twinlines, helmets, lenses, cool air tubes. Dust Collectors - filters, solenoids, diaphragm valves, pulse boards. Control Panels - motor starters, fuses, transformers, disconnects?

For bidding purposes, replacement components are not to be considered.

Per NFPA 33, section 6.5.4.2(a), the interior of any recirculation path is

Class I, Division 2. The motor is not in the air stream. This is why a TEFC motor is scheduled. A direct drive fan with an explosion proof motor would meet and exceed the intent of the specifications. A plenum fan would be required to meet the scheduled flow rate, horsepower, and other values, while fitting in the allotted space.
