Into the homestretch: Kendeda Building in photos

Living Building photos

The Kendeda Building for Innovative Design switched from temporary to permanent electricity in April — a milestone as the deep-green project on the campus of the Georgia Institute of Technology heads into its construction homestretch.

With heavy rains and materials challenges slowing things down a bit, construction is now expected to reach “substantial completion” in July, As the various subcontractors enter the homestretch, here’s a view in photos at construction highlights so far in 2019. For a closer look at the processes and materials, click the “in-depth” links where they appear. (For a photo essay on construction in 2018, click here).

ELECTRIFICATION: In early April, an electrician for Eckhardt Electric prepares the main switching room in the basement for the switch from temporary to permanent power.

 

SOLAR INSTALLATION: The building isn’t yet tied to its permanent power source: 915 solar panels are in the process of being installed on the canopy over the building’s roof by Hannah Solar. The solar array is projected to provide more than 105 percent of the power that will be used by the Kendeda Building — making it one of the first net positive buildings in the Southeast.

 

Living Building photosTHE CANOPY: The most dramatic change on the outside of the building since the start of the year has been the outsized steel canopy that will serve as the rack for the solar panels. Installed by Southeastern Steel, it also will shade the generously sized porch on the building’s west and south sides.

 

STEEL TRUSS COLUMNS: Where it overhangs the building, the canopy is supported by distinctive steel columns, designed by structural engineers at Uzun + Case. The canopies wide brim defines the large porch, some of which is considered programmable space. The steel trusses that protrude as triangles along the sides of the main post stiffen the column while requiring less steel to be used in construction.

 

ROOF: As with any construction project, completing the roof was vital before moving on to exterior finishes and much of the trade work. The Kendeda Building construction team had the misfortunate of near-record amounts of rain before “dry-in” was complete. Here, employees from Roof Management Inc. work around ducts to lay down material for a 60-millimeter thermoplastic polyolefin (TPO) membrane roof.

From right to left: gypsum-board sheathing painted with a moisture barrier, mineral wool insulation, a mortar guard and brick. Where metal cladding replaces brick as the exterior face, a vapor barrier replaces the mortar guard. Inside the envelope, an additional layer of un-faced fiberglass batts is being installed between the metal studs.

The mineral wool insulation is composed largely of slag (waste material from iron smelting) that has been melted, formed into fibers and then pressed into mats. IN-DEPTH

MASONRY: Masons from Cronos Construction complete brick work that wraps much of  the building. They’re North Carolina-made Green Leaf bricks, which are composed of 100 percent recycled material. IN-DEPTH

 

Living Building photos, waste reduction, Patterson ServicesWASTE: A goal to reduce landfill waste by more than 90 percent requires far more separation of recyclable materials than on most construction sites. Here’s a dumpster restricted to brick and mortar, which will find new life as aggregate material. IN-DEPTH

MOVING INSIDE: The focus of the project shifted to the interior as the building’s shell neared completion.

Rainwater will be collected on the roof and treated in the basement. In the photo at the top of this article, Patricia Powell, also of BKI, is welding a similar water pipe.

Living Building photos, waterLANDSCAPE: While the interior went into full swing, other subcontractors were able to begin work the infrastructure for the landscape’s intricate outdoor water cycle.  Here, Caleb Ogden, assistant site superintendent for Skanska USA, points to an underground greywater storage tank. Used greywater from the building will be pumped from here to a constructed wetland for treatment before returning to the natural environment. The building is scheduled for completion at the end of May, but don’t be surprised if completed finishes and landscapes bleed into June.

 

Living Building photosTAKING SHAPE: By mid-May, flowers were blooming, students had graduated and almost all the solar panels were installed on the Kendeda Building’s canopy, giving passerby a better sense of the dramatic look that the solar array provides for the building.
