Investigating Limestone

CHICAGO, IL – Simpson Gumpertz & Heger (SGH) was out this week at the Shrine investigating the condition of the limestone on the interior face of the West Pediment Wall. The brick below the limestone needs to be removed to install steel plates for the new steel to tie back into the existing building structure. The brick condition at this location is poor due to being open to the weather for two season. More brick was removed than anticipated. The removal of the brick compromised the stability of the limestone. SGH was on site to make recommendations and construction continues to get ready for the steel delivery in January.

Truss No. 1 Mock Up

Late last week, Wiss, Janney, Elstner Associates (WJE) was on site at the fabrication shop for the mock up of Truss No. 1. The mock up is done to demonstrate the proposed range of aesthetic effects and workmanship of steel surfaces and welded and bolted conditions. Truss No. 1 is now ready to be primed and painted. Truss No. 2 and 3 are both half way done. Steel is on schedule for a late January delivery to the job site!

This Week’s Work…

Work done this week at the Shrine…

Scaffolding was removed from the east wall behind the altar and moved to the west wall and erected on the choir loft. This will allow for access to the high pediment for masonry repairs.

Workers used the Genie lift to remove the purlins that attach to Truss No. 1 and the west pediment wall. This will allow access for the masons to make masonry repairs.

Shop fabrication continues: Truss No. 1, 2 & 3 are being made. Miscellaneous smaller steel angles, plates, etc. are done and will be delivered to the site next week.

Temporary power has been set up. The electrical to the building was removed after the fire. Temporary power has been set up to use for this phase of construction for the use of heat and power tools.

Simpson Grumpertz & Heger (SGH) has provided details and specifications for the rebuild of the limestone at the southwest corner. These stones were removed immediately after the fire due to unsafe conditions.

Wiss, Janney, Elstner Associates (WJE) has provided direction for the tie in of the existing steel in the southwest corner. The heat of the fire badly damaged this area of the building, compromising the existing steel that will remain. WJE has provided the direction and details to tie the steel back into the building to be able to take future uplift wind loads.

Raffin Construction Co. provided an updated detailed schedule. January 26, 2018 is the delivery date for the steel to be on site.

Inspecting & Numbering Limestone

CHICAGO, IL – Engineers from Simpson Gumpertz & Heger (SGH) were on site at the Shrine inspecting and numbering the limestone pieces that were removed right after the fire. These pieces will go back on the building like larger puzzle pieces. The pieces were removed right after the fire due to the unsafe structure underneath the southwest corner of the building. Masonry work this Fall has been building back this corner and the stone will be put back into place.

Visit to & Blessing at Fabrication Shop

CHICAGO, IL – Canon Talarico visited the fabrication shop to see the progress of the steel connections and also to provide a blessing! The existing steel trusses and purlins were damaged during the heat of the fire and cannot hold the strength needed for the new roof. The labor intensive process of shop drawing review has led to the fabrication of the steel trusses. The fabrication shop has labeled each piece and with the use of the drawings will connect the pieces into what will become the trusses.

We all look forward to the erection of the new trusses in December!!

Prepping Steel before the Roof

CHICAGO, IL – This week work continues at the Shrine. The steel in the Southwest corner of the building, opposite the bell tower, is steel that is to remain. Prior to the roof replacement the steel is prepped and primed with a protective coat of paint. This area is accessed by scaffolding that is built from the ground up on the inside of the southwest corner of the building.

The Genie Lift has Arrived!

CHICAGO, IL – The use of Genie Lift is now on site at the Shrine helping the workers reach those high areas. Scaffolding will still be used at the far east and west walls but the lift will be able to reach almost everything else. Scaffolding has been installed on the far east wall for tuckpointing.

Tuckpointing is the method of repairing weathered joints in old masonry. The joints are cut or raked and then wet mortar is placed in the joint.
