Project progress timeline


5/7/2019 The statewide road restrictions have been lifted and the tower removal and replacement are scheduled for Wednesday, May 15th “Weather Permitting”. To complete this portion of the project, the use of a crane is required. The crane will arrive on site between 7:30-8:00 am and begin setting up. We are expecting the crane to be on site unit approximately 2:00 pm. During this time, access to, from and around the building will be heavily restricted. The public street will be shut down during this time. Please make arrangements to have your vehicles out of the parking garage and off of James Ave. 


4/5/2019 Flushing the system of any loose debris will take place on Monday, April 8th. After the system has been flushed the lines will be filled. At that time, brief access to all second-floor units will be required to bleed the lines of any air. This is very important to prevent the system from becoming air locked. Will Stein will be accompanying the techs and providing access to any home per approval of the owner. Thank you for your cooperation. 


3/15/2019 The chiller is in, the wall has been repaired and we received notice from the crane company that enough snow has melted for them to safely set the tower. Unfortunately, the City of Minneapolis issued the spring load road restrictions to take effect today. This means the crane will not be allowed on the road until after the restrictions have been lifted. I apologize for the inconvenience and will keep everyone informed of any updates. Please see the below link to the MNDOT notification.

2/21/2019 Today the block wall will be put back in place. All of the new equipment is in place and any remaining items can be brought in through the door. At this point, the work will need to wait until spring when the tower on the roof can be removed with the use of a crane and the new one installed. After that happens, the system will be filled and the process of removing air from the system will begin. During this time, access to all units may be needed to bleed the air from the line. Proper notice will be given before this take place. 


2/8/2019 The crew is working hard to connect the new with the old. The new equipment and piping is very sharp looking and will operate great. 



2/6/2019 The chiller was delivered on Friday, February 1st and placed into the mechanical room. The crew will be working to connect the new chiller to the existing lines that service the building. There will be periodic times of noise during the connection process. 



1/31/2019 Like everything this week, the weather has impacted the delivery of the new chiller. The truck scheduled to deliver the chiller broke down due to the dangerously cold weather. They are hoping to try again tomorrow Friday, February 1st, but may need to deliver it on Monday the 4th. 



1/28/2019 The new chiller is scheduled to arrive onsite Wednesday the 30th and will be placed into the mechanical room on Thursday, January 31st.

Monday 28th- The crew will be welding.

Tuesday 29th- Pouring new concrete pads and cleaning up the site. 



1/25/2019 the chiller has been removed successfully!

The pipefitters will be back on Monday, 1/28/2019 to begin working on the piping to connect the new chiller. An update will be posted when the new chiller will be delivered and the install will begin. 



1/22/2019 The crew is on site completing the dismantling of the chiller and installing the supports to remove the old and bring in the new equipment. During this process, there will be noise during the proposed times. In order to cut the metal, torches will be used. This will create a smell of something burning. Please note, extra caution is taken and fire extinguishers are on hand. 



1/17/2019 There were members of the crew that became sick and we’re now pushing the electrical and equipment dismantling to Monday, January 21st. We apologize for the change in plans. 



1/15/2019 With the wall open, the project has begun. We have the electricians scheduled for Thursday, January 17th. They will be disconnecting the power to the water tower and chiller so the dismantling of the components can begin on Friday, January 18th. During this process, there will be periodic noise and vibrations. The noise will be kept between 8 am to 3:30 pm. 


1/14/2019 The boiler room wall has been removed successfully. We apologize for the noise and appreciate your patience. Please see the below photos and videos of the work. 




The boiler room wall removal is scheduled to begin Monday, January 14th. The structural engineer changed the wall that will be opened. The wall parallel to 36th St. will be opened as this is a non-load bearing wall. The parking spot(s) in this area will be impacted.
