10. 9.3 Drawings / 10.3 SOW Contractor shall replace windows with Hammered chicken wire glass that is reinforced by mat backing.

“Chicken Wire” glass windows are no longer made…not available at least by an USA manufacturer. That style may be available with a special order from China but that source does not fall under the Buy American requirements.

2 of 6 (Amendment 0001, 6 September 2019) areas plumbing. Will the scope of work be adjusted to eliminate the areas that we do not have access to?

Answer: The Scope of Work will not be adjusted. The areas in question will need to have the blocked off areas removed and have sashes installed.

There are numerous areas where sash windows have been removed and blocked up. The inside of the hanger has had offices built in those areas and are being utilized. The scope of work does not address this situation of removing drywall, framing and T-bar to access the window systems and we were not given access to those areas during the job walk.

Answer: See Response to question #5.

14. 9.7 Drawings 10.7 SOW

Remove paint from all windows (Lead Base Paint). We understand what the base would like to accomplish, however a majority of the windows have been painted on the inside of building some many years prior with lead base paint and are no longer accessible by any means other than removing the buildouts that have taken place over the years.

Synopsis:

Added: Jul 25, 2019 12:37 pm The 452 Operational Contracting Office at March Air Reserve Base intends to issue an Invitation for Bid (IFB) for a firm-fixed price construction contract for maintaining exterior paint for Building 300, (PDPG 17-0119) at March ARB CA. The statement of work requires an asbestos and lead base paint survey prior to start of construction; results will determine if abatement is necessary. In addition to paint, work will also consist of removing and replacing corrugated metal siding on the hangar doors, two exterior doors/frames, and broken window panes. This is a historical building and all work shall have the same appearance as the original.

Answer: If a window needs to be replaced or paint needs to be removed and don’t have access from the inside, possibly the entire sash will need to removed and re-installed.

15. It appears that this project which was painting of the hanger, replacing siding on the hanger doors , 2 exterior door replacements and replacing a few broken window panes have since morphed into a much larger project that has not been fully investigated as to the interior situation of the current conditions. The timeframe to accomplish this project is also not in line with prior projects in the past of a typical restoration of the exterior of a Hanger. 90 days is pretty much too short a time to complete a project of this magnitude, especially when the base is requiring custom made sash windows and doors that could take 90 days to manufacture after base approval let alone the time required for removal and installation.
