As the weather helps construction crews make progress on the final layer of the Hagfors Center roof, crews prepare the steel structure on the stairwells and lobby for installation of the glass curtain wall in the coming weeks. Following is a summary of construction work expected on the Hagfors Center this week.

    Stairwell work. Crews will begin installing the glass curtainwall on the west stairway this week. (The photo above shows crews welding the frame on the west stair in preparation for this work). Crews are also staring work on the frames on the north stair this week.

  • Rooftop greenhouse. Construction of the base for the rooftop greenhouse (see photo, at right).
  • Lobby exterior. Work continues this week on the horizontal steel support for the three-story glass lobby enclosure. The concrete columns will be uncovered for this work, and then recovered after the horizontal steel support installation is complete in order to protect them during ongoing construction work in the lobby area.
  • Installation of the white, reflective roof is underway, weather permitting.

    Roof work. Weather has slowed installation of the final roofing layer, but some progress was made last week, The high roof (the roof of the fourth floor) should be done this week. The photo at right shows crews working on installation of the white roof layer, which reflects sunlight and heat and is part of the building’s LEED certification requirements.

  • Window frames and glass. Window installation on the north wing is complete except for areas around the stairway and the skip hoist. Installation work continues on the west wing.
  • Precast exterior. Crews will demobilize the mobile crane the mobile crane this week. It is no longer needed for installation of the precast exterior; the remaining remaining precast installation can be completed without the crane.
