Window Replacement Update

After a series of in-depth conversations, site meetings, vendor meetings, and scenarios, we have received good direction to move forward. JLG and CDA along with our Historical Registration Consultant, Lesley Gilmore, assembled a series of options to address the window conditions:

1.       Remove, refurbish, and reinstall existing units on floors 2 to 5

2.       Remove and replace with new units floors 2 to 5

3.       Replace Glazing on 1st floor in existing frames

With Dick Anderson’s coordination, we developed initial budgets and timeframes for these options. This information was then assembled into a report for the State Historical Preservation Officer that reviewed and ultimately relayed his recommendation for replacement and the information to the Federal National Parks. The National Parks agent agreed the replacement was acceptable and has precedence of similar window units being replaced in compliance with NPS Guidelines and a qualified expense for tax credits. We received this notification on July 31.

Over the next two weeks, JLG and CDA are proceeding with drawings and specifications to identify this scope that will then be handed to DAC for pricing in August. If bids are in alignment, we anticipate final ordering no later than the end of September to keep on the original construction schedule.

Four concrete patches now fill the space where pipe bollards were removed. 

The soffit is being patched back in on the east side of the building. 

Most of the metal stud framing on the 5^th floor is almost complete, and the new duct work is moving right along. This floor is also getting ready for cable trays, so the crew began installing hangers on the east side. 

Two chilled water lines and a steam line in the 5th floor fan room were cut and capped without interrupting the 3rd floor, which is where several Yellowstone County offices are located. 

The layout of full-height wall and door openings began on the 4th floor. In order to get ready for ductwork on this floor, duct hanger installation began.
