Question 1 What is CLIN 0003 - External Track Assembly? I don't see any information on that.. We've installed robots on tracks to blast components on numerous past projects so that is why I am curious to know what "External Track Assembly" entails.

For the medium size cabinets:


3.2.1.2.2 Each cabinet (medium size) shall have a turntable with a diameter of 40'' that is rated for a minimum of 500 lb. on casters with sealed bearings.


3.2.1.2.2 Each cabinet (medium size) shall have a turntable with a diameter of 40'' that is rated for a minimum of 500 lb. on casters with sealed bearings.


3.2.1.2.3 The inside cabinets shall have a track system designed for the turntable to be secured in the booth with the capability to be moved out of the door with minimum force. The track system shall be designed with the capability to extend the tracks outside of the cabinet to allow operators to place aircraft components onto an external cart. A cart mounted turntable system with tracks shall be included for each of the four medium cabinets.


Question 2. CFM calculations yield 650-815 CFM.... Do you have static pressure required?


See para 3.1.1.4 in the solicitation statement of work, the details will impact your duct size and pressure which I assume will vary with each offeror:


3.1.1.4 The blast booths shall meet the American Conference of Governmental Industrial Hygienist (ACGIH) recommendations for ventilation and noise expo exposure (Figure VS-80-02). The data is listed in the ACGIH's "Industrial Ventilation, A Manual of Recommended Practice for Design, 26th Edition". ACGIH's Figure VS-80-02 is provided in the appendix of this SOW. The requirements detailed in Figure VS-80-02 are also listed below:
3.1.1.4.1 All duct velocities shall have minimum 4000 fpm (20m/s).
3.1.1.4.2 All openings shall have a minimum of 500 fpm (2.5m/s) inward velocity
3.1.1.4.3 All cabinets shall have a minimum of 20 air changes per minute.
3.1.1.5 All units must be capable of operating with 460 Volt, 3 Phase, and 60 Hz electrical supply.

Question 3. Type of filtration? Cartridge? Cyclone? Other?


3.1.1.2 The blast cabinets shall be complete, self-contained abrasive blasting cabinets, each with a dedicated reclamation and dust collection system. The blast cabinets shall recirculate clean air within the plant working environment without any exhaust to the outside using primary High Efficiency Particulate Air (HEPA) filters and secondary HEPA filters.


Question 4. Efficiency required?


460V-3-60 electric power is the best response I can provide to that question.


Question 5. What will be blasted in the cabinets? Steel? Aluminum? Other?


3.1.1.1 The blast cabinets shall be designed for constant duty production work in an industrial environment. The systems shall consist of a pressure blast cabinet set up for use with Aluminum Oxide media and Glass Bead media capable of blasting parts weighing up to 500 pounds.


3.2.2.1 Two of the four medium cabinets will use glass bead media. The other two of the four medium cabinets will use aluminum oxide media (220 grit).


3.3.2.1 One of the three small cabinets will use Glass Bead media. The other two of the three small cabinets will use aluminum oxide media (220 grit, 150grit).


Question 6. Voltage? 460V-3-60?


3.1.1.5 All units must be capable of operating with 460 Volt, 3 Phase, and 60 Hz electrical supply.


Question 7. Independent units or can we tie into one central collector?


3.1.1.2 The blast cabinets shall be complete, self-contained abrasive blasting cabinets, each with a dedicated reclamation and dust collection system.---------
Question 8. US Steel certificates required? No

This area shall include a 3ft safety clearance distance for all electrical panels, maintenance locations, waste removal path, and access points. All maintenance panels and chamber doors shall be able to be opened a full 90º once placed at final place of operation. A proposed layout of all four units operating in this footprint shall be included with the drawings submitted for para 3.1.1.14 as part of the bid proposal.


3.3.1.1 The work chamber shall have a minimum inside dimensions of 42" W x 42" D x 32" H. Due to space restrictions, the work chamber shall not exceed 48'' W x 48'' D x 40'' H accept for by a few inches but the cabinet will still need to fit in the area and get through the entrance door.

Questions and Answers:


Question 1:


It is stated that the equipment must be ISO-9001:2015 certified. Since
ISO-9001 is only one quality management system, this requirement severely
limits the contracting team's ability to receive competitive proposals because
it rules out any organizations that operate under other quality management
systems. Will the contracting team consider removing this requirement from the
solicitation?


Answer 1:


3.1.1.15.1 The Nationally Recognized Testing Laboratories (NRTLs)
certification shall be met for all blast systems provided in lieu of the
ISO9001:2015 certification, see para 3.4.4.


Question 2:


As a follow up question. If removing that requirement will not be
considered, will the contracting team consider allowing for an NRTL
certification on all provided machines in lieu of the ISO9001:2015
documentation? The 3rd party NRTL certification requirement would hold
manufacturers to a higher standard than the ISO-9001:2015 requirements and
would enable organizations with other quality management systems to bid on the
project. This would greatly increase the contracting team's ability to
receive competitive proposals.


Answer 2:


3.4.4 The United States Occupational Safety and Health Administration (OSHA)
requires that 38 different types of products, devices, assemblies, or systems
used in the workplace be "approved" (i.e., tested and certified) by
third-party organizations identified as Nationally Recognized Testing
Laboratories (NRTLs). The NRTLs certification shall be met for all blast
systems provided in lieu of the ISO9001:2015 certification. It is our
understanding that the 3rd party NRTL certification requirement would hold
manufacturers to a higher standard than the ISO-9001:2015 requirements while
also allowing organizations with other quality management systems to bid on
this solicitation.
