Answer: ** Design and certification of overhead rail system is responsibility of the contractors.

Engineering drawing for hangar 1 & 2 systems have previously been provided. Additionally as-built drawings for previous projects in the Fuel Cell and Hangar 3 will be provided post award. The overhead rail system must meet OSHA 29 CFR 1926.502 (d) (15), i.e. each rail must be rated for 15,000 lbs total support capacity (5,000 lbs/worker x 3 workers).

12. Do your systems need to be passable systems?

Answer: NO

13. Am I understanding your requirement correctly:

You are asking for a 60’ track system with one rail and 3 shuttles. This system will not be passable for any workers. Is this correct?

Answer: Refer to Scope of Work

14. Is it possible to get a waiver on:

The shuttle being made of extruded aluminum

You are asking for a class A SRL (stops within 24”) with a MAF of 1350. Can we get a waiver and to only provide a class B, with a MAF of 900

Answer: ** Design and certification of overhead rail system is responsibility of the contractors.
