Specs

There appears to be very little mention of equipment and controls being Class 1 & 2, Div 1 rated or 'explosion proof' within the drawings and specs referenced, while there are many points of mention in the specs (especially plenum doors and lifts) that 'relate' to the hazardous locations noted on the electrical plans. We see the explosion proof motors noted in some mechanical schedules but only one sheet of controls plans for the paint booth indicating that everything in the AHU's will be explosion proof.

The plenum door spec indicates much more detail with switches and controls, etc. all being explosion proof methods and materials. Please clarify the extent of PMB, Wash, Mechanical, Plumbing, & Integrated Automation requirements within the hazardous locations as noted on the electrical plans.

The PMB Bay is Class II, Division 1, Group G for the explosive dust:

Motors and equipment required to be explosion-proof are noted on the drawings and equipment schedules.

Provide low voltage wiring and control devices in this space with explosion-proof, non-sparking devices. The Paint Bay and the Paint Mixing/Paint Storage/Cleaning spaces are Class I, Division 1, Group C with the same requirements as noted above for the PMB Bay. Electrical drawing EP-104 shows the Wash Rack Bay as being Class I, Division 1, Group C:

This classification applies only to the electrical services in this space, and not to the HVAC, plumbing or wastewater treatment systems.

The structural drawings call for up to 90-ft piles to be installed and specification 31 62 13 .20 Precast/Prestressed Concrete Piles

Pile splices are not permitted.

section 3.3.8 does not allow for splicing of piles. Typically, any moment concerns on the piles are alleviated the deeper the splice is located. The pile lengths on this project would require a splice 30- to 40-ft below cut-off elevation to allow for more options of equipment and material selection, if a splice were allowed. This could lead to a more cost effective piling price. Would the government please consider the use of splices for this project?

The Rotating Media Screw Metering System description search leads to a proprietary product. This metering system is not a common necessity for these types of blasting systems since augers will crush plastic media.

Would another means of metering media be allowed?

Alternate means of metering will be reviewed, but will need to be approved by the Government.

Will a dust collector design be allowed which utilizes recirculation of filtered air and 20% fresh air return that does not involve any equipment outdoors or conveying of any dust material?

Bid Per RFP.

The drawings and specification for the P1035 Project Paint Bay indicate misc. plenums and ducts along with incorporating a building into a paint

Bid Per RFP area. Our experience is it would be a much better design to utilize a booth insert within the allotted space, the advantages are:

1. Better Controlled Air-Flow

2. Control Air Cure Cycles

3. Reduces Stratification

4. Better Lighting

5. Smooth walls for ease of maintenance

6. Better filter loading for reduced operation cost

7. 80/20 or 90/10 Recirculation- Recirculation provides for much smaller Air Make Up Systems and provided extreme reduction in utilities including electric, gas and chilled water (lower operating cost)

8. Booth Design meets NFPA, OSHA, IBC and IFC Codes

9. Mitigates the need for tile ceiling

10. Plenum doors can be designed to mount on booth or building structure

We have included a concept drawing of a similar application as a reference

Please advise if the Government will accept this design in lieu of the specification as written

185 Geotech report 4.8

The Geotechnical Report from GET Solutions discusses a number of deep foundation types and provides detailed information regarding driven steel piles, driven precast concrete piles and auger cast in place piles.

The Report reads as if any of these three deep foundation systems are acceptable for the proposed work at the site. However, the drawings provided include only details for precast driven piles. In lieu of precast driven piles, would other drilled deep foundations be acceptable for this project due to desirable schedule and cost impacts?

Confirm the hook lift height is 20ft?

What kind of jib? What span? What height of crane? Is jib manual or powered rotation?

Bid per specifications, span is 14'.

Is there a particular color requirement for the concrete mix in precast concrete wall panels?

Refer to Exterior Materials Legend on sheet AE202. See also PPI round 2 response to item 123.

Project specifications, section 034500, Note 2.7.1 indicate an R-value of 15.2 or greater and also indicate a U-factor of 0.048. The drawings indicate that the insulated panels are shown as being 14" thick (5 1/2" exterior side, 3" insulation, and 5 1/2" interior side). This panel configuration may not be able to obtain the indicated U-factor rating given the number of openings in the panels, setback of insulation around edges of wall panels, solid areas of concrete in the wall panels, etc. Can we make adjustment to the panel configuration in order to meet the U-

Do the special coatings on the precast panels extend full height, or just up to the drop down ceiling?

High Performance Coatings are to extend to 6" above the ceiling, and extend to deck where there is no ceiling.
